    California Adaptation Forum 2014  ASAP Aug 29 2014

     

    What do you get when you bring together local, state & federal government representatives; academics; nonprofit practitioners; and private sector adaptation specialists? A lot of conversations, sharing lessons learned, ideas for future collaboration, and new friends. Last week’s California Adaptation Forum (#CAF14) brought together about 800 people to talk about climate adaptation and resilience. With breakout sessions and presentations focusing on everything from technical guidance on developing sea level rise projections to discussions on community engagement to determining success (or progress) in adaptation, the conference touched on all facets of building resilience to climate change.  American Society of Adaptation Professionals (ASAP) was proud to sponsor this event and play a small part in making it a success. Having this much energy and excitement (more people attended CAF14 than last year’s National Adaptation Forum) at a regional adaptation event bodes very well for the progress of the field a whole. Congratulations to all the ASAP members (new and old), the Local Government Commission, and thanks to The Kresge Foundation and all the other sponsors [including Point Blue Conservation Science] who made this event a success.

    Record decline of ice sheets: Scientists map elevation changes of Greenlandic and Antarctic glaciers

    Posted: 20 Aug 2014 08:05 AM PDT

    Researchers have for the first time extensively mapped Greenland’s and Antarctica’s ice sheets with the help of the ESA satellite CryoSat-2 and have thus been able to prove that the ice crusts of both regions momentarily decline at an unprecedented rate. In total the ice sheets are losing around 500 cubic kilometers of ice per year….The areas where the researchers detected the largest elevation changes were Jakobshavn Isbrae (Jakobshavn Glacier) in West Greenland and Pine Island Glacier in West Antarctica.
    Since February 2014 scientists know that the Jakobshavn Isbrae is moving ice into the ocean at a record speed of up to 46 meters a day.
    The Pine Island Glacier hit the headlines in July 2013. Back then AWI scientists reported that a table iceberg as large as the area of Hamburg had broken off the tip of its ice shelf. But whereas both the West Antarctic Ice Sheet and the Antarctic Peninsula, on the far west of the continent, are rapidly losing volume, East Antarctica is gaining volume — though at a moderate rate that doesn’t compensate the losses on the other side of the continent….

    Winged Warnings: Built for survival, birds in trouble from pole to pole


    By Alanna Mitchell Environmental Health News August 25, 2014 Part 1 of Winged Warnings, published in conjunction with National Geographic

    The ice of Antarctica doesn’t faze birds. Nor does the heat of the tropics. They thrive in the desert, in swamps, on the open ocean, on sheer rock faces, on treeless tundra, atop airless mountaintops and burrowed into barren soil.

    Some fly nonstop for days on end. With just the feathers on their backs, they crisscross the hemisphere, dodging hurricanes and predators along the way, pinpointing scarce food, tracking down safe resting places, arriving unerringly at a precise spot, year after year.

    Sole descendents of the dinosaurs, birds have penetrated nearly every ecosystem on Earth and then tailored their own size, habits and colors to each one, pollinating, dispersing seeds, controlling bugs, cleaning up carrion and fertilizing plants, all the while singing notes so beguiling that hearing them makes even the urban dweller pause to listen.

    Birds are the planet’s superheroes, built for survival. But for all their superhuman powers, they are in trouble.

    Southwest U. S. may face ‘megadrought’ this century

    Posted: 27 Aug 2014 09:25 AM PDT

    Due to global warming, scientists say, the chances of the southwestern United States experiencing a decade long drought is at least 50 percent, and the chances of a “megadrought” – one that lasts over 30 years – ranges from 20 to 50 percent over the next century. Because of global warming, scientists say, the chances of the southwestern United States experiencing a decade long drought is at least 50 percent, and the chances of a “megadrought” — one that lasts over 30 years — ranges from 20 to 50 percent over the next century.

    The study by Cornell University, University of Arizona and U.S. Geological Survey researchers will be published in a forthcoming issue of the American Meteorological Society’s Journal of Climate.

    For the southwestern U.S., I’m not optimistic about avoiding real megadroughts,” said Toby Ault, Cornell assistant professor of earth and atmospheric sciences and lead author of the paper. “As we add greenhouse gases into the atmosphere — and we haven’t put the brakes on stopping this — we are weighting the dice for megadrought conditions.”
    As of mid-August, most of California sits in a D4 “exceptional drought,” which is in the most severe category.
    Oregon, Arizona, New Mexico, Oklahoma and Texas also loiter between moderate and exceptional drought. Ault says climatologists don’t know whether the severe western and southwestern drought will continue, but he said, “With ongoing climate change, this is a glimpse of things to come. It’s a preview of our future.” Ault said that the West and Southwest must look for mitigation strategies to cope with looming long-drought scenarios. “This will be worse than anything seen during the last 2,000 years and would pose unprecedented challenges to water resources in the region,” he said. In computer models, while California, Arizona and New Mexico will likely face drought, the researchers show the chances for drought in parts of Washington, Montana and Idaho may decrease. Beyond the United States, southern Africa, Australia and the Amazon basin are also vulnerable to the possibility of a megadrought. With increases in temperatures, drought severity will likely worsen, “implying that our results should be viewed as conservative,” the study reports. “These results help us take the long view of future drought risk in the Southwest — and the picture is not pretty. We hope this opens up new discussions about how to best use and conserve the precious water that we have,” said Julia Cole, UA professor of geosciences and of atmospheric sciences.

    Winged Warnings: Built for survival, birds in trouble from pole to pole


    By Alanna Mitchell Environmental Health News August 25, 2014 Part 1 of Winged Warnings, published in conjunction with National Geographic

    The ice of Antarctica doesn’t faze birds. Nor does the heat of the tropics. They thrive in the desert, in swamps, on the open ocean, on sheer rock faces, on treeless tundra, atop airless mountaintops and burrowed into barren soil.

    Some fly nonstop for days on end. With just the feathers on their backs, they crisscross the hemisphere, dodging hurricanes and predators along the way, pinpointing scarce food, tracking down safe resting places, arriving unerringly at a precise spot, year after year.

    Sole descendents of the dinosaurs, birds have penetrated nearly every ecosystem on Earth and then tailored their own size, habits and colors to each one, pollinating, dispersing seeds, controlling bugs, cleaning up carrion and fertilizing plants, all the while singing notes so beguiling that hearing them makes even the urban dweller pause to listen.

    Birds are the planet’s superheroes, built for survival. But for all their superhuman powers, they are in trouble.

    Globally, one in eight – more than 1,300 species – are threatened with extinction, and the status of most of those is deteriorating, according to BirdLife International. And many others are in worrying decline, from the tropics to the poles.

    “If birds are having issues, you have to think about whether humans are going to have issues too,” said Geoff LeBaron, an ornithologist with the National Audubon Society based in Massachusetts and international director of the Christmas Bird Count.

    Globally, one in eight – more than 1,300 species – are threatened with extinction, and the status of most of those is deteriorating, according to BirdLife International.In North America’s breadbasket, populations of grassland birds such as sweet-trilling meadowlarks are in a free-fall, along with those everywhere else on the planet. Graceful fliers like swifts and swallows that snap up insects on the wing are showing widespread declines in Europe and North America. Eagles, vultures and other raptors are on the wane throughout Africa. Colonies of sea birds such as murres and puffins on the North Atlantic are vanishing, and so are shorebirds, including red knots in the Western Hemisphere. Sandpipers, spoonbills, pelicans and storks, among the migratory birds dependent on the intertidal flats of Asia’s Yellow Sea, are under threat. Australian and South American parrots are struggling and some of the iconic penguins of Antarctica face starvation.

     

    While birds sing, they also speak. Many of their declines are driven by the loss of places to live and breed – their marshes, rivers, forests and plains – or by diminished food supply. But more and more these days the birds are telling us about new threats to the environment and potentially human health in the coded language of biochemistry. Through analysis of the inner workings of birds’ cells, scientists have been deciphering increasingly urgent signals from ecosystems around the world.

    Like the fabled canaries that miners once thrust into coal mines to check for poisonous gases, birds provide the starkest clues in the animal kingdom about whether humans, too, may be harmed by toxic substances. And they prophesy what might happen to us as the load of carbon-based, planet-warming gases in the atmosphere and oceans climbs ever higher.

    “And no birds sing”

    Rachel Carson was the earliest and best-known scientist to link the fate of birds to that of humans. Alerted by reports of sharp declines in birds of prey and songbirds, she began to examine the effects of the pesticide DDT. It was the first modern synthetic pesticide, in wide use after World War II to control mosquitoes and other insects.

    Her book Silent Spring, published in 1962 – the title echoes the poet John Keats’ celebrated line “And no birds sing” – explained that DDT moved up through food chains, from the insects it was designed to kill to the creatures that ate them. It accumulated inexorably in tissues, organs and fat in top predators such as peregrine falcons, ospreys, bald eagles and pelicans. “Over increasingly large areas of the United States, spring now comes unheralded by the return of the birds, and the early mornings are strangely silent where once they were filled with the beauty of bird song,” Carson wrote.

    But it wasn’t just the birds. Carson reasoned that if DDT could accumulate in birds, it would accumulate in humans, too. “We have subjected enormous numbers of people to contact with these poisons without their consent and often without their knowledge,” she wrote. By 1972, after public uproar, DDT was banned in the United States and eventually banned around the world except in malaria-prone countries, mostly in Africa.

     

    Yet DDT’s legacy remains. Traces of the persistent pesticide, classified as a “probable” carcinogen, are still found in most people around the world today and in the land and water they depend on. And, again, it’s birds that are telling us this tale: A recent study reported that birds of prey in South Carolina still carry as much DDT and other legacy pesticides in their bodies as they did before such chemicals were banned in the 1970s, “suggesting exposure has not declined substantially over the past 40 years.” And in the town of St. Louis, Mich., near an old chemical plant, robins are still dropping dead of DDT poisoning, registering some of the highest levels ever recorded in wild birds.

    The idea that birds tell us about our own health has gained even more scientific traction in the decades since Silent Spring as biochemical analysis has become more precise. Much of that work stemmed from studies conducted on the Great Lakes, the world’s first and biggest testing ground for contaminants and birds.

    The work of Canadian Wildlife Service toxicologist Glen Fox and others began with tales from terns and other fish-eating birds. He found high levels of polychlorinated biphenyls or PCBs, in the Great Lakes and their sediments, and enlarged thyroids that were producing little hormone in the birds. Thyroid hormones are critical for ensuring proper brain development, so altering them can impair intelligence, motor skills and behavior. Building up in food webs just like DDT, PCBs were banned in the United States in 1978, with the rest of the world to follow.

    “The birds really told the story, elegantly.” –Theo Colborn, scientist and co-author of Our Stolen Future By the late 1980s, zoologist Theo Colborn, then at the World Wildlife Fund, began examining the Great Lakes studies to see if she could discern a big picture. She recalls reading through stacks of academic papers and tracking the findings in a chart.

     

    The results were stunning: The Great Lakes’ top 16 or 17 bird predators were vanishing. The problem stemmed from assaults on the endocrine system, which controls hormones and reproduction. And that, in turn, was linked to manmade substances in the water and prey. So, birds’ ability to reproduce crashed in multiple ways: Young failed to hatch; babies were deformed; male young were feminized; female young were more masculine; chicks’ immune systems were impaired; parents forgot how to parent. The concept of the “endocrine disruptor” was born.

    “The birds really told the story, elegantly,” said Colborn, who co-authored the 1996 book Our Stolen Future, which chronicled the threats of hormone disruption.

    Proxies for people

    Once the chemicals’ effects on birds were established, scientists began looking more intensively at humans. Their studies have suggested that those same chemicals also may be altering human hormones. Part of a pregnant mother’s load of chemicals passes to her baby while it is still in the womb, with evidence mounting that suggests the chemicals can alter development of the baby’s brain and its reproductive and immune systems, leading to troubles later in life, such as lower intelligence, behavioral problems and reduced fertility. Some studies suggest a link between endocrine disruptors and a greater risk of prostate and breast cancers and other diseases. Some research even suggests chemicals can switch genes on and off, affecting grandchildren and great-grandchildren – all the unexposed generations, humanity’s future.

    When it comes to chemicals and broad planetary changes, birds have shown us that they are in a unique position to tip us off to health threats. That doesn’t mean that birds are more vulnerable than humans, said Pierre Mineau, an expert on pesticide ecotoxicology and its effects on birds who recently retired from Environment Canada. In fact, amphibians such as frogs are likely more vulnerable because their thin skins draw in the chemicals and because they are in constant contact with polluted water. But they are much harder to find, count and assess than birds.

    “Birds can tell us a lot about what’s going on around us that we might not be able to see.” –Christy Morrissey, University of Saskatchewan  Birds, on the other hand, are highly visible. People track them, notice them, care deeply about them. Of all the non-human creatures on Earth, birds are by far the most closely scrutinized, said Nicola Crockford, international species policy officer with BirdLife International in England. That translates into a robust body of knowledge about how and where birds live, a baseline for scientists seeking to monitor change.

    Looking at birds gives humans the unsurpassed ability to identify and quantify chemical threats across time and space around the globe, noted Christy Morrissey, an ecotoxicologist at the University of Saskatchewan. “Birds can tell us a lot about what’s going on around us that we might not be able to see,” she said.

    Perched atop many food webs, birds of prey such as eagles and falcons soak up chemicals from the things they eat. That means looking at birds is a proxy for looking at plants, insects, fish and small mammals, over time. Not only that, but about one in five birds migrates, so those birds are sampling pollutants in many parts of the world. Scientists can capture birds, test them, band them, let them go and then catch them years later to see what’s changed. Birds normally maintain relatively stable numbers, unlike small mammals, so when their populations take a dive, it means something noteworthy is going on.

    Many birds also live a long time – for eagles and owls, decades – meaning scientists can study a bird’s life cycle and then extrapolate what would happen to a human exposed to the same chemicals from birth to death, Morrissey said. Reading birds is a reasonable stand-in for a human epidemiological study, especially when it comes to the endocrine system, she added. “Vertebrates are vertebrates,” she said. “The endocrine system is so similar [in birds and mammals]. We all have circulating hormones and a thyroid that regulates the system.” Today, studies on how endocrine-disrupting chemicals affect birds is a main plank of future research that may also have implications for human health.

    Beyond DDT and PCBs

    On the prairies of Canada, Morrissey is trying to decipher where sanderlings, red knots and semipalmated sandpipers are picking up contaminants as they travel. Then she’s tracking those chemicals – which include PCBs and polycyclic aromatic hydrocarbons or PAHs – through a bird’s lifespan, examining whether they affect its ability to fatten up and sustain a long migration. She’s also looking at whether the chemicals have affected brain development, robbing them of the ability to navigate and learn when to molt. Early results of birds dosed in captivity in the first days of life say they do.

    Barn owls are dying from massive stomach bleeds caused by eating rats laced with rodenticides.In other words, she’s investigating not just whether the chemicals impair the birds’ ability to reproduce, but also their ability to thrive. “If they’re not able to fatten, they won’t make it,” she said, as grackles, orioles and yellow warblers sang in the background.

     

    Morrissey and Mineau also are at the forefront of research globally on the newest class of pesticide, the neonicotinoids or neonics for short. Mineau helped unlock the puzzle in the mid-1990s of how the organophosphate pesticide monocrotophos, which replaced DDT-like insecticides, killed off masses of endangered Swainson’s hawks in Argentina. He said he was originally relieved that neonics replaced organophosphates, which are ferocious bird-killers, but now his research on neonics, including a report for the American Bird Conservancy, has him worried. They are extremely persistent in the environment and water soluble, which means they move around, he said. They take down nearly any insect or crustacean that comes along. “The real issue is the ecosystem-wide effects,” Mineau said.

    Sanderlings, Pete Myers 

    Contaminants may affect shorebirds’ ability to fatten up before migrating.

    Rat-killing poisons also are causing agonizing deaths of not just rodents, but the birds that eat them. Barn owls in Canada, for example, are dying from massive stomach bleeds caused by an extra-strong class of rodenticide.

    And in Southeast Asia, tens of millions of vultures have perished from feasting on carcasses of livestock treated with diclofenac, an anti-inflammatory drug. Three vulture species now are teetering on the edge of extinction. In a victory, hopefully not too late, the drug is no longer used for livestock in Asia. Its use is on the rise in Europe, however, particularly in Spain, where it has killed thousands of vultures, eagles and other carrion-eaters in recent years.

    Traces of people’s prescription drugs, washed into sewers, also are collecting in fish, which means ospreys and other birds of prey are sometimes exposed to therapeutic doses of heart medications, antidepressants and other drugs.

    Perched atop many food webs, birds of prey such as eagles and falcons soak up chemicals from the things they eat. That means looking at birds is a proxy for looking at plants, insects, fish and small mammals, over time. Adding to their burden, birds are contaminated with a whole new spate of pollutants, such as perfluorinated compounds or PFCs, used to manufacture such substances as Teflon and stain-resistant coatings. Brominated chemicals used as flame retardants in furniture foam and electronics also are collecting in bird tissues, just like PCBs. Kestrels exposed in laboratories have fewer chicks, smaller eggs and some behavior issues, such as bad parenting skills and more aggressive males. Some flame retardants seem to mimic estrogen, others mimic or block testosterone. It all adds up to a load of dozens of chemicals, many with consequences still unknown.

     

    In Sweden, for example, ornithologists are racing to figure out why white-tailed sea eagles on the coast of the Baltic Sea, devastated by DDT and PCBs in the 1970s, are again experiencing thin shells and deformed embryos, said Cynthia de Wit, a professor of environmental science at Stockholm University who specializes in human and wildlife exposure to synthetic chemicals. “It’s very alarming; we really don’t know why,” she said, adding that it’s possible that old chemicals are being “remobilized” or that new ones are having effects not yet assessed.

    Scientists are closely examining the effects of heavy metals such as mercury and lead. A recent study of Antarctic skuas showed those contaminated with mercury, a byproduct of coal-burning power plants, have more trouble reproducing. Mercury even seems to alter the singing of songbirds. Lead, sometimes lethal to birds of prey that eat it in gut piles left by hunters, also seems to have subtle effects, perhaps interfering with their ability to navigate around obstacles.

    Why do people care about birds?

    Pragmatically, humans have relied on birds’ superpowers for millennia to let us in on their secrets. Imagine forest-dwellers of ancient times, anxious to avoid snakes and jaguars, listening for the alarm calls of sharp-sighted, high-flying, omnipresent birds. Think of medieval sailors, following fish-eating birds to find out where they should throw their nets, or rejoicing that shore was near when they caught sight of a land-loving cormorant instead of the albatrosses that favor the open ocean. Sailors of old may have even followed the paths of migratory birds to colonize new lands, said Garry Donaldson, a conservation biologist with the Canadian Wildlife Service.

    Birds signal the presence of dangerous pathogens such as West Nile virus.

    And throughout history, humans have considered birds to be our protectors, the vigilant sentinels, writes the Nobel laureate immunologist Peter Doherty in his 2012 book Their Fate is our Fate: How Birds Foretell Threats to our Health and Our World. “Way back to mythological times, guard duty has been part of the avian job description. Gods with the body of a man and the head of a bird, like the ibis, falcon, hawk or heron, watched over the ancient Egyptians…Sacred geese in the temple of the Goddess Juno alerted the exhausted defenders of ancient Rome to a nocturnal attack by marauding Gauls,” Doherty wrote.

    And to many Native American and other indigenous cultures, birds are messengers sent by the creator, or symbols of change, or protectors and healers. Today they play that role in a non-spiritual sense: They send warnings to tribes about the health risks of eating fish tainted with industrial pollutants.

    Birds also herald the presence of pathogens, such as avian influenza and West Nile virus, noted Nicholas Komar, a biologist who specializes in vector-borne diseases with the Centers for Disease Control and Prevention in Fort Collins, Colo. When birds are found dead of West Nile, it’s proof humans also are at risk. Infected birds don’t transmit the virus to humans – mosquitoes do – but they are a sign that it is present in the environment. He is pressing for more testing of dead birds as a swift means of detecting flashpoints for potential transmission to humans.

    Apart from data points, birds also provide us with sheer joy – in their songs and striking colors, and from the spectacle of watching them swoop through the air. “Which of us has not wished we could do that?” asked John Fitzpatrick, director of the Cornell Lab of Ornithology in Ithaca, New York. He said humans intuitively respond to birds’ colors and varied voices, which signal that the year is marching on. “They move with the seasons. It’s a major annual heartbeat we feel.”

    “Thou wast not born for death, immortal Bird!
    No hungry generations tread thee down;
    The voice I hear this passing night was heard
    In ancient days by emperor and clown.” 
    John Keats  

     

    In his “Ode to a Nightingale,” Keats declares steadfastly that birds must prevail despite us, just as they always have.

     

    But will Keats’s prophecy stand the test of time? In the past five centuries, about 150 bird species have gone extinct at the hand of humanity, including the passenger pigeon and the dodo, according to research by Duke University biologist Stuart Pimm. But that rate is speeding up and will be 10 times higher by the end of this century if trends persist, his study calculates. BirdLife’s most recent survey shows that 197 species are critically endangered, which means they are just one disease outbreak or a couple of bad breeding seasons away from extinction. Hotspots of risk are hot parts of the world: The Atlantic forests of Brazil and the islands of Indonesia are a particular worry because so many birds live there, so much of the land is being cleared and few protections are in place.

    Omens of a dangerous future

    The wild card for birds, with the potential to magnify all past and future threats, is the high-carbon world humans have created through the burning of fossil fuels for energy. Scientists are struggling to chronicle the intricate layers of fallout from climate change — and to glimpse once again what birds foretell about humanity’s fate. Frank Gill, who wrote the textbook Ornithology and was president of the National Audubon Society, said the scientific effort has shifted dramatically from the time when Carson’s work on chemicals set the standard. Today, biologists are examining complex, continental effects of climate change on birds’ abundance and distribution.

    For instance, brown pelicans, taken off California’s endangered species list in 2009, are in the throes of a catastrophic breeding failure this year, said Dan Anderson, professor emeritus of ecotoxicology and marine ornithology at University of California, Davis, who recently completed his 46th annual census of the birds. The cause appears to be an El Niño event with its strongly warmer ocean currents and high winds. While El Niños are natural and periodic phenomena, they are expected to intensify and become more common. Anderson and others are assessing what effect that could have on pelicans, noting that it would take two or three terrible breeding seasons in a row to seriously affect the population.

    Birds have many superpowers that humans can only envy.  Yet we also have the power to make sure birds continue to sing. Already, Audubon’s Christmas Bird Count has found that the “center of abundance” of more than half of North American species that stay through the winter has shifted as much as 200 miles north over the past 60 years, a response to warmer average temperatures, LeBaron said. And a study of 40 western North American songbird species found that those inhabiting the highest elevations on mountaintops are moving farther up, rather than farther north, to flee the heat, said David King, a research wildlife biologist at the U.S. Forest Service’s Northern Research Station in Massachusetts. Inevitably, they will run out of places to go.

     

     Omens from the birds are not easy to read. So far, they are telling us that this world is shifting where they can live, forcing them to change the timing of their migrations and nesting, making their food harder to find and perhaps fostering diseases such as the West Nile virus.

    Pete Myers

    Brown pelican populations in California are crashing this year, likely due to warmer ocean currents.

     

    Birds, people share superpowers

    Birds have many superpowers that humans can only envy. But we have extraordinary powers, too: The ability to alter the chemistry of the air and the sea, and to create synthetic substances that live longer than we do. Yet we also have the power to make sure birds continue to sing.

    Fitzpatrick pointed to the data from around the world that impassioned birdwatchers are feeding to scientists at websites such as eBird.org – which is growing by 40 percent a year – so they can map birds in real time. Citizen science is part of the reason, for instance, that waterfowl numbers have been bouncing back in North America as people band together to protect and restore wetlands.

    “Birds do recover,” Fitzpatrick said, “if we pay attention to what they’re saying.”

    In “A Fable for Tomorrow,” the opening chapter of Silent Spring that describes a fictional, nightmarish, poisoned town, Carson wrote, “It was a spring without voices. On the mornings that had once throbbed with the dawn chorus of robins, catbirds, doves, jays, wrens, and scores of other bird voices there was now no sound; only silence lay over the fields and woods and marsh.”

    Muted, perhaps, but not silenced, birds keep sending us winged warnings.

    NOAA analysis reveals significant land cover changes in U.S. coastal regions

    Posted: 18 Aug 2014 05:41 PM PDT

    A new NOAA nationwide analysis shows that between 1996 and 2011, 64,975 square miles in coastal regions–an area larger than the state of Wisconsin–experienced changes in land cover, including a decline in wetlands and forest cover with development a major contributing factor.
    Overall, 8.2 percent of the nation’s ocean and Great Lakes coastal regions experienced these changes. In analysis of the five year period between 2001-2006, coastal areas accounted for 43 percent of all land cover change in the continental U.S.
    This report identifies a wide variety of land cover changes that can intensify climate change risks, such as loss of coastal barriers to sea level rise and storm surge, and includes environmental data that can help coastal managers improve community resilience. “Land cover maps document what’s happening on the ground. By showing how that land cover has changed over time, scientists can determine how these changes impact our plant’s environmental health,” said Nate Herold, a NOAA physical scientist who directs the mapping effort at NOAA’s Coastal Services Center in Charleston, S.C. Selected Regional Findings — 1996 to 2011:

    • The Northeast region added more than 1,170 square miles of development, an area larger than Boston, New York City, Philadelphia, Baltimore, and the District of Columbia combined
    • The West Coast region experienced a net loss of 3,200 square miles of forest (4,900 square miles of forests were cut while 1,700 square miles were regrown)
    • The Great Lakes was the only region to experience a net wetlands gain (69 square miles), chiefly because drought and lower lake levels changed water features into marsh or sandy beach.
    • The Southeast region lost 510 square miles of wetlands, with more than half this number replaced by development
    • Many factors led to the Gulf Coast region’s loss of 996 square miles of wetlands, due to land subsidence and erosion, storms, human-made changes, sea level rise, and other factors
    • On a positive note, local restoration activities, such as in Florida’s Everglades, and lake-level changes enabled some Gulf Coast and Southeast region communities to gain modest-sized wetland areas, although such gains did not make up for the larger regional wetland losses
    • C-CAP moderate-resolution data on the Land Cover Atlas encompasses the intertidal areas, wetlands, and adjacent uplands of 29 states fronting the oceans and Great Lakes. High-resolution data are available for select locations.

    All C-CAP data sets are featured on the Digital Coast.

    Trees, shrubs invading critical grasslands, diminish cattle production

    Posted: 18 Aug 2014 01:13 PM PDT

    Half of Earth’s land mass is made up of rangelands, which include grasslands and savannas, yet they are being transformed at an alarming rate. Woody plants, such as trees and shrubs, are taking over, leading to a loss of critical habitat and causing a drastic change in the ability of ecosystems to produce food — specifically meat. Researchers have now quantified this loss.

    While the phenomenon of woody plant invasion has been occurring for decades, for the first time, we have quantified the losses in ecosystem services,” said Osvaldo Sala, Julie A. Wrigley Chair and Foundation Professor with ASU’s School of Life Sciences and School of Sustainability. “We found that an increase in tree and shrub cover of one percent leads to a two percent loss in livestock production.” And, woody-plant cover in North America increases at a rate between 0.5 and two percent per year…. In recent years, the U.S. government shelled out millions of dollars in an effort to stop the advance of trees and shrubs. The U.S. Natural Resources Conservation Service spent $127 million from 2005-2009 on herbicides and brush management, without a clear understanding of its economic benefit….While ranchers clearly depend on grasslands to support healthy livestock, ecosystems also provide a range of other services to humans. Stakeholders such as conservationists, farmers, builders, government entities and private landowners, depend on the land for a variety of reasons and each has different values and land use needs….

    Earth can sustain more terrestrial plant growth than previously thought, analysis shows

    August 26, 2014

    A new analysis suggests the planet can produce much more land-plant biomass — the total material in leaves, stems, roots, fruits, grains and other terrestrial plant parts — than previously thought. The study, reported in Environmental Science and Technology, recalculates the theoretical limit of terrestrial plant productivity, and finds that it is much higher than many current estimates allow.  “When you try to estimate something over the whole planet, you have to make some simplifying assumptions,” said University of Illinois plant biology professor Evan DeLucia, who led the new analysis. “And most previous research assumes that the maximum productivity you could get out of a landscape is what the natural ecosystem would have produced. But it turns out that in nature very few plants have evolved to maximize their growth rates.”

     

    Study Shows Where on the Planet New Roads Should and Should Not Go

    Aug. 28, 2014 — Researchers have created a ‘large-scale zoning plan’ that aims to limit the environmental costs of road expansion while maximizing its benefits for human development. More than 25 million kilometres of new roads will be built worldwide by 2050. Many of these roads will slice into Earth’s last wildernesses, where they bring an influx of destructive loggers, hunters and illegal miners. Now, an ambitious study has created a ‘global roadmap’ for prioritising road building across the planet, to try to balance the competing demands of development and environmental protection. The map has two components: an ‘environmental-values’ layer that estimates that natural importance of ecosystems and a ‘road-benefits’ layer that estimates the potential for increased agriculture production via new or improved roads. The authors of the new study, recently published in the journal Nature, write that by combining these layers they have identified areas where new roads have most potential benefit, areas where road building should be avoided, and conflict areas “where potential costs and benefits are both sizable.” “It’s challenging but we think we’ve identified where in the world new roads would be most environmentally damaging,” said co-author Professor Andrew Balmford from the University of Cambridge’s Department of Zoology…..Areas with carbon-rich ecosystems with key wilderness habitats, such as tropical forests, were identified as those where new roads would cause the most environmental damage with the lease human benefit, particularly areas where few roads currently exist. “Our study also shows that in large parts of the world, such as the Amazon, Southeast Asia, and Madagascar, the environmental costs of road expansion are massive,” said Christine O’Connell from the University of Minnesota, USA. The authors emphasise that there will be serious conflicts in the coming decades….Given that the total length of new roads anticipated by mid-century would encircle the Earth more than 600 times, the authors point out that there is “little time to lose.”… full story

    Marine Protected Areas Inadequate for Protecting Fish and Ocean Ecology, Study Finds

    Aug. 28, 2014 — A new study reports that an expansion of marine protected areas is needed to protect fish species that perform key ecological functions. According to investigators from the Wildlife Conservation Society and other organizations, previous efforts at protecting fish have focused on saving the largest numbers of species, often at the expense of those species that provide key and difficult-to-replace ecological functions. Many vital ecological functions of ocean ecology are performed by fish species that also are food for millions of people. This study uncovers a significant problem: the world’s most ecologically valuable fish communities are currently vulnerable and are being missed by the world’s current network of marine protected areas. If these tropical fish populations and the ecological services that they provide are to be ensured, say the authors, then the world’s existing marine protected area network must be expanded. The paper appears in the current online edition of Ecology Letters. “The recognition that all species are not the same and that some play more important and different roles in ocean ecology prompted this new investigation. The study was expected to identify regions with vulnerable fish populations, something that has been sidetracked by the past species richness focus,” said Dr. Tim McClanahan, WCS Senior Conservationist and a co-author of the study. “If you lose species with key functions, then you undermine the ability of the ocean to provide food and other ecological services, which is a wake up call to protect these vulnerable species and locations. Our analysis identifies these gaps and should provide the basis to accelerate the protection of ocean functions.” The authors of the study compiled a global database on tropical coastal fish populations from 169 locations around the world, focusing on species occurring in 50 meters of water or less. The team compared these data with distribution maps for 6,316 tropical reef fish species. Human threats such as fishing, pollution, and climate change were also included in the analyses…..full story

     

    Fish and coral smell a bad neighborhood: Marine protected areas might not be enough to help overfished reefs recover

    Posted: 21 Aug 2014 11:13 AM PDT

    Pacific corals and fish can both smell a bad neighborhood, and use that ability to avoid settling in damaged reefs. Damaged coral reefs emit chemical cues that repulse young coral and fish, discouraging them from settling in the degraded habitat, according to new research. The study shows for the first time that coral larvae can smell the difference between healthy and damaged reefs when they decide where to settle.

     

    Salmon recolonizing newly reconnected zones in rivers of Adour basin

    The impact of constructing passes that allow salmon to cross hydroelectric dams and recoloniae newly reconnected zones in the Adour basin has been the focus of recent study. Using population genetics tools, researchers have shown that the sources of this recolonization are very probably the sectors downstream of these passes and that little genetic diversity is lost during recolonization of the newly available zones.  These results suggest a strong potential for the evolution of these newly formed populations.

    More wolf spiders feasting on American toads due to invasive grass, study shows

    Posted: 27 Aug 2014 10:18 AM PDT

    An invasive grass species frequently found in forests has created a thriving habitat for wolf spiders, who then feed on American toads, a new University of Georgia study has found. Japanese stiltgrass, which was accidentally introduced to the U.S. in the early 1900s, is one of the most pervasive invasive species and has spread to more than a dozen states in the past century, particularly in the Southeast. Typically found along roads and in forests, it can survive in widely diverse ecosystems and has been found to impact native plant species, invertebrate populations and soil nutrients. In a new study recently published in the journal Ecology, UGA researchers found that Japanese stiltgrass also is affecting arachnid predators: Lycosid spiders, commonly known as wolf spiders, thrive in the grass. As their numbers grow, more spiders then feed on young American toads, ultimately reducing the amphibian’s survival wherever this grass grows. John Maerz, an associate professor in UGA’s Warnell School of Forestry and Natural Resources and one of the paper’s authors, said they found the grass had the greatest negative impact on toad survival in forests where toad survival was naturally high.

    “In other words, the grass is degrading the best forests for young toad survival,” Maerz said. “Another important finding was that the invasive grass affects toads by changing interactions among native species rather than the grass having a direct effect on the native toads.”

    Jayna DeVore, who led the project while earning her doctorate in the Warnell School, said people often don’t fully realize how much structural changes in an environment can affect how animals interact. “Ecosystems are so incredibly complex that it can be surprisingly difficult to foresee just how environmental changes, such as an invasion, will affect organisms living in affected areas,” said DeVore, who is now a postdoctoral fellow with the University of Sydney in Australia. “I think that one of the unique things about this study is that it not only documents the fact that this plant invasion reduces the survival of a native species, but also determines the mechanism through which that occurs.”…

    Birds Bursting Into Flames over State-of-the-Art Solar Plant

    By ELLEN KNICKMEYER and JOHN LOCHER PublishedAugust 18, 2014

    IVANPAH DRY LAKE, Calif. (AP) — Workers at a state-of-the-art solar plant in the Mojave Desert have a name for birds that fly through the plant’s concentrated sun rays — “streamers,” for the smoke plume that comes from birds that ignite in midair.  Federal wildlife investigators who visited the BrightSource Energy plant last year and watched as birds burned and fell, reporting an average of one “streamer” every two minutes, are urging California officials to halt the operator’s application to build a still-bigger version.  The investigators want the halt until the full extent of the deaths can be assessed. Estimates per year now range from a low of about a thousand by BrightSource to 28,000 by an expert for the Center for Biological Diversity environmental group.  The deaths are “alarming. It’s hard to say whether that’s the location or the technology,” said Garry George, renewable-energy director for the California chapter of the Audubon Society. “There needs to be some caution.”…

    Our shorelines are filling up again with the rustling of wings, quiet “kew-ing” calls and sudden bursts of hundreds of shorebirds in flight. Fall migration is bringing about a million of them back to our beaches, mudflats and rocky shores from the far north where they raised their broods on the tundra and prairies under the midnight sun. For the first time ever, they have a day set aside in their honor: World Shorebirds Day. It’s set to start this September 6 with a worldwide count to assess their populations and celebrations around the globe.

    Gyorgy Szimuly, a Hungarian ornithologist with 35 years of birding and conservation experience, initiated the day as an international celebration and focus on shorebirds. An annual shorebird count of Bay Area shorebirds already occurs and Point Reyes Bird Observatory/Point Blue has been keeping local data on Bay Area shorebirds since the 1970s. (You can find the results on their website.) According to the 2011 “State of the Birds of San Francisco Bay” report, our local shorebirds are doing well, for the most part, with the majority at stable population numbers….

    Greenhouse Gas Emissions Are Growing, and Growing More Dangerous, Draft of U.N. Report Says

    Runaway growth in the emission of greenhouse gases is swamping all political efforts to deal with the problem, raising the risk of “severe, pervasive and irreversible impacts” over the coming decades, according to a draft of a major new United Nations report. Global warming is already cutting grain production by several percentage points, the report found, and that could grow much worse if emissions continue unchecked. Higher seas, devastating heat waves, torrential rain and other climate extremes are also being felt around the world as a result of human emissions, the draft report said, and those problems are likely to intensify unless the gases are brought under control. The world may already be nearing a temperature at which the loss of the vast ice sheet covering Greenland would become inevitable, the report said. The actual melting would then take centuries, but it would be unstoppable and could result in a sea level rise of 23 feet, with additional increases from other sources like melting Antarctic ice, potentially flooding the world’s major cities…..

     

    Why global warming is taking a break

    Posted: 19 Aug 2014 08:30 AM PDT

    The average temperature on Earth has barely risen over the past 16 years. ETH researchers have now found out why. And they believe that global warming is likely to continue again soon. Global warming is currently taking a break: whereas global temperatures rose drastically into the late 1990s, the global average temperature has risen only slightly since 1998 — surprising, considering scientific climate models predicted considerable warming due to rising greenhouse gas emissions. Climate sceptics used this apparent contradiction to question climate change per se — or at least the harm potential caused by greenhouse gases — as well as the validity of the climate models. Meanwhile, the majority of climate researchers continued to emphasise that the short-term ‘warming hiatus’ could largely be explained on the basis of current scientific understanding and did not contradict longer term warming. … In a study published in the latest issue of the journal Nature Geoscience, the researchers conclude that two important factors are equally responsible for the hiatus.

    El Niño warmed Earth

    One of the important reasons is natural climate fluctuations, of which the weather phenomena El Niño and La Niña in the Pacific are the most important and well known. “1998 was a strong El Niño year, which is why it was so warm that year,” says Knutti. In contrast, the counter-phenomenon La Niña has made the past few years cooler than they would otherwise have been.

    Although climate models generally take such fluctuations into account, it is impossible to predict the year in which these phenomena will emerge, says the climate physicist. To clarify, he uses the stock market as an analogy: “When pension funds invest the pension capital in shares, they expect to generate a profit in the long term.” At the same time, they are aware that their investments are exposed to price fluctuations and that performance can also be negative in the short term. However, what finance specialists and climate scientists and their models are not able to predict is when exactly a short-term economic downturn or a La Niña year will occur.

    Longer solar cycles

    According to the study, the second important reason for the warming hiatus is that solar irradiance has been weaker than predicted in the past few years. This is because the identified fluctuations in the intensity of solar irradiance are unusual at present: whereas the so-called sunspot cycles each lasted eleven years in the past, for unknown reasons the last period of weak solar irradiance lasted 13 years. Furthermore, several volcanic eruptions, such as Eyjafjallajökull in Iceland in 2010, have increased the concentration of floating particles (aerosol) in the atmosphere, which has further weakened the solar irradiance arriving at Earth’s surface….

     

    Cause of global warming hiatus found deep in the Atlantic Ocean

    Posted: 21 Aug 2014 11:14 AM PDT

    Observations show that the heat absent from the Earth’s surface for more than a decade is plunging deep in the north and south Atlantic Ocean, and is part of a naturally occurring cycle. Subsurface warming in the ocean explains why global average air temperatures have flatlined since 1999, despite greenhouse gases trapping more solar heat at Earth’s surface.

     

    Record decline of ice sheets: Scientists map elevation changes of Greenlandic and Antarctic glaciers

    Posted: 20 Aug 2014 08:05 AM PDT

    Researchers have for the first time extensively mapped Greenland’s and Antarctica’s ice sheets with the help of the ESA satellite CryoSat-2 and have thus been able to prove that the ice crusts of both regions momentarily decline at an unprecedented rate. In total the ice sheets are losing around 500 cubic kilometers of ice per year….The areas where the researchers detected the largest elevation changes were Jakobshavn Isbrae (Jakobshavn Glacier) in West Greenland and Pine Island Glacier in West Antarctica.
    Since February 2014 scientists know that the Jakobshavn Isbrae is moving ice into the ocean at a record speed of up to 46 meters a day.
    The Pine Island Glacier hit the headlines in July 2013. Back then AWI scientists reported that a table iceberg as large as the area of Hamburg had broken off the tip of its ice shelf. But whereas both the West Antarctic Ice Sheet and the Antarctic Peninsula, on the far west of the continent, are rapidly losing volume, East Antarctica is gaining volume — though at a moderate rate that doesn’t compensate the losses on the other side of the continent….

    Ocean warming could drive heavy rain bands toward poles

    Posted: 18 Aug 2014 08:32 AM PDT

    In a world warmed by rising atmospheric greenhouse gas concentrations, precipitation patterns are going to change because of two factors: one, warmer air can hold more water; and two, changing atmospheric circulation patterns will shift where rain falls. According to previous model research, mid- to high-latitude precipitation is expected to increase by as much as 50 percent. Yet the reasons why models predict this are hard to tease out….Using a series of highly idealized model runs, Lu et al. found that ocean warming should cause atmospheric precipitation bands to shift toward the poles. The changes in atmospheric circulation brought on by a warming ocean should cause an increase in the intensity and frequency of extreme precipitation events at mid- and high-latitudes, and a reduction in the same near the equator. The changes would mean that, for high-latitude regions, now-rare storms would become much more common. The authors tested the effect of ocean warming on atmospheric circulation and precipitation using a highly idealized “aquaplanet” model, a representation of the Earth that was just sea and sky, but no land. They ran the model at a range of spatial resolutions and found that the changes in precipitation that stem from changing circulation patterns may possibly outweigh changes that derive from other factors.

    The vast reservoir of carbon stored in Arctic permafrost is gradually being converted to carbon dioxide after entering the freshwater system in a process thought to be controlled largely by microbial activity. However, researchers say that sunlight and not bacteria is the key to triggering the production of CO2 from material released by Arctic soils.

     

    Butterflies’ evolutionary responses to warmer temperatures may compromise their ability to adapt to future climate change

    Posted: 18 Aug 2014 08:32 AM PDT

    Members of the brown argus butterfly species that moved north in response to recent climate change have evolved a narrower diet dependent on wild Geranium plants, researchers report. However, butterflies that did not move north have more diverse diets, including plants such as Rockrose that are abundant in southern parts of the UK…So although rapid evolutionary changes have allowed the brown argus to move north and track the warming climate, they have led to a more restricted diet. This increased specialization may limit this butterfly’s continued spread north, into areas where Rockrose is common. “Our data confirm that rapid evolutionary change in a species’ diet is important for responding to recent climate change, but as a consequence, variation in this ecologically-important trait may be lost,” said Dr. Jon Bridle, co-author of the Ecology Letters study. “In addition, unlike the brown argus, many butterflies already have restricted diets, so they may be unable to rapidly evolve changes in their diets to survive ongoing climate change,” said co-author Dr. James Buckley.

    Lifeguards reopen [San Diego] beaches after lightning strikes; at least 1 home damaged

    A lightning strike over the ocean during Wednesday’s storm.

    By Derek Staahl Story Published: Aug 20, 2014 at 8:48 AM PDT

    SAN DIEGO — A summer storm brought heavy rain and hail to parts of San Diego County Wednesday, generating flash-flood warnings and unusual coastal lightning that prompted a temporary closure of beaches from Del Mar to Point Loma. As of 1 p.m., there were 93 lightning strikes tallied over land in San Diego County and 127 over water, said National Weather Service forecaster Tina Stall….A line of thunderstorms began moving over south and central San Diego County around 7:30 a.m., upping the risk for ground and ocean lightning strikes, according to the National Weather Service.

    As the unsettled atmospheric conditions continued to intensify, the city of San Diego closed all of its beaches to the public at 9:30 a.m., said Lee Swanson, spokesman for the San Diego Fire-Rescue Department. The closure was lifted an hour later, after the NWS advised that the imminent lightning hazards had abated. Such conditions along the local [San Diego] coastline are rare, Swanson said….

    Southwest U. S. may face ‘megadrought’ this century

    Posted: 27 Aug 2014 09:25 AM PDT

    Due to global warming, scientists say, the chances of the southwestern United States experiencing a decade long drought is at least 50 percent, and the chances of a “megadrought” – one that lasts over 30 years – ranges from 20 to 50 percent over the next century. Because of global warming, scientists say, the chances of the southwestern United States experiencing a decade long drought is at least 50 percent, and the chances of a “megadrought” — one that lasts over 30 years — ranges from 20 to 50 percent over the next century.

    The study by Cornell University, University of Arizona and U.S. Geological Survey researchers will be published in a forthcoming issue of the American Meteorological Society’s Journal of Climate.

    For the southwestern U.S., I’m not optimistic about avoiding real megadroughts,” said Toby Ault, Cornell assistant professor of earth and atmospheric sciences and lead author of the paper. “As we add greenhouse gases into the atmosphere — and we haven’t put the brakes on stopping this — we are weighting the dice for megadrought conditions.”
    As of mid-August, most of California sits in a D4 “exceptional drought,” which is in the most severe category.
    Oregon, Arizona, New Mexico, Oklahoma and Texas also loiter between moderate and exceptional drought. Ault says climatologists don’t know whether the severe western and southwestern drought will continue, but he said, “With ongoing climate change, this is a glimpse of things to come. It’s a preview of our future.” Ault said that the West and Southwest must look for mitigation strategies to cope with looming long-drought scenarios. “This will be worse than anything seen during the last 2,000 years and would pose unprecedented challenges to water resources in the region,” he said. In computer models, while California, Arizona and New Mexico will likely face drought, the researchers show the chances for drought in parts of Washington, Montana and Idaho may decrease. Beyond the United States, southern Africa, Australia and the Amazon basin are also vulnerable to the possibility of a megadrought. With increases in temperatures, drought severity will likely worsen, “implying that our results should be viewed as conservative,” the study reports. “These results help us take the long view of future drought risk in the Southwest — and the picture is not pretty. We hope this opens up new discussions about how to best use and conserve the precious water that we have,” said Julia Cole, UA professor of geosciences and of atmospheric sciences.

    Severe drought is causing the western US to rise like a spring uncoiling

    Posted: 21 Aug 2014 11:15 AM PDT


    The severe drought gripping the western United States in recent years is changing the landscape well beyond localized effects of water restrictions and browning lawns. Scientists have used GPS data to discover that the growing, broad-scale loss of water is causing the entire western US to rise up like an uncoiled spring. Investigating ground positioning data from GPS stations throughout the west, Scripps researchers Adrian Borsa, Duncan Agnew, and Dan Cayan found that the water shortage is causing an “uplift” effect up to 15 millimeters (more than half an inch) in California’s mountains and on average four millimeters (0.15 of an inch) across the west. From the GPS data, they estimate the water deficit at nearly 240 gigatons (62 trillion gallons of water), equivalent to a six-inch layer of water spread out over the entire western U.S….Results of the study, which was supported by the U.S. Geological Survey (USGS), appear in the August 21 online edition of the journal Science….For Cayan, a research meteorologist with Scripps and USGS, the results paint a new picture of the dire hydrological state of the west. “These results quantify the amount of water mass lost in the past few years,” said Cayan. “It also represents a powerful new way to track water resources over a very large landscape. We can home in on the Sierra Nevada mountains and critical California snowpack. These results demonstrate that this technique can be used to study changes in fresh water stocks in other regions around the world, if they have a network of GPS sensors.”

    West’s historic drought stokes fears of water crisis

    Dust blows around a farmer as he discs a dry, fallowed field in Maxwell, Calif., on Aug. 12, 2014. Max Whittaker/Prime for The Washington Post

    By Joby Warrick, The Washington Post Posted: 08/18/14

    WILLOWS, Calif. When the winter rains failed to arrive in this Sacramento Valley town for the third straight year, farmers tightened their belts and looked to the reservoirs in the nearby hills to keep them in water through the growing season. When those faltered, some switched on their well pumps, drawing up thousands of gallons from underground aquifers to prevent their walnut trees and alfalfa crops from drying up. Until the wells, too, began to fail. Now, across California’s vital agricultural belt, nervousness over the state’s epic drought has given way to alarm. Streams and lakes have long since shriveled up in many parts of the state, and now the aquifers — always a backup source during the region’s periodic droughts — are being pumped away at rates that scientists say are both historic and unsustainable. One state-owned well near Sacramento registered an astonishing 100-foot drop in three months as the water table, strained by new demand from farmers, homeowners and municipalities, sank to a record low. Other wells have simply dried up, in such numbers that local drilling companies are reporting backlogs of six to eight months to dig a new one.

    In still other areas, aquifers are emptying so quickly that the land itself is subsiding, like cereal in a bowl after the milk has drained out….

    Hardest hit is California. As of last month, nearly 60 percent of the state is officially in an “exceptional” drought — the highest level, above “severe” — and meteorologists are seeing no immediate change in a relentlessly dry forecast. Indeed, scientists are warning that the state’s cyclical droughts could become longer and more frequent as the climate warms. If that happens, the elaborate infrastructure built to deliver water to the state’s 38 million residents and 27 million cultivated acres may not survive the challenge, new research suggests. Already the drought has led to the “greatest water loss ever seen in California agriculture,” said a study last month by researchers at the University of California at Davis.
    A massive shift to groundwater helped farmers survive this year, but if pumping continues at current rates, some of the state’s aquifers could soon be depleted, the study warned. One of the authors, Richard Howitt, a professor emeritus of resource economics, likened the problem to a “slow-moving train wreck.” “A well-managed basin is used like a reserve bank account,” Howitt said. “We’re acting like the super rich who have so much money they don’t need to balance their checkbook.”…

    Damage to aquifers is viewed as more serious because, once depleted, an aquifer takes far longer to replenish — often decades or more, compared with a few years for an empty reservoir, said Thomas Harter, a groundwater specialist from the university’s Land, Air and Water Resources Department. “It’s a downward path,” he said. “We cannot do what we did this year on a permanent basis.”…

    But environmentalists and many scientists argue that any long-term solution would have to balance competing interests, including the need for clean water for growing cities as well as thriving habitats for fish and wildlife. A recent modeling study by researchers at UC Davis’s Center for Watershed Sciences suggested that California’s economy could weather far more severe water shortages — and even a decades-long drought similar to the ones that occurred millennia ago. But doing so would require not only more storage for water but also a general willingness by all sides to make do with less. “Keeping the balance may mean reducing the number of irrigated acres, but if you manage the system well you can still do amazing things with it,” said Jay Lund, a professor of civil and environmental engineering who participated in the exercise. Lund said he believes Californians are more capable of adjusting, compared with people in other water-challenged parts of the world, because they already possess experience and expertise and “because we happen to be rich, which helps.”

    Despite his engineer’s optimism, Lund keeps a prayer of sorts taped to his office door. It is a two-word play on the University of California’s motto, “Fiat Lux,” or, in Latin, “let there be light.”

    “Fiat Pluvia,” Lund’s sign reads. Let there be rain.

     

    Climate change will threaten fish by drying out southwest U.S. streams, study predicts

    Posted: 18 Aug 2014 01:12 PM PDT

    Fish species native to a major Arizona watershed may lose access to important segments of their habitat by 2050 as surface water flow is reduced by the effects of climate warming, new research suggests. Most of these fish species, found in the Verde River Basin, are already threatened or endangered. Their survival relies on easy access to various resources throughout the river and its tributary streams. Their survival relies on easy access to various resources throughout the river and its tributary streams. The species include the speckled dace (Rhinichthys osculus), roundtail chub (Gila robusta) and Sonora sucker (Catostomus insignis). A key component of these streams is hydrologic connectivity — a steady flow of surface water throughout the system that enables fish to make use of the entire watershed as needed for eating, spawning and raising offspring. Models that researchers produced to gauge the effects of climate change on the watershed suggest that by the mid 21st century, the network will experience a 17 percent increase in the frequency of stream drying events and a 27 percent increase in the frequency of zero-flow days….

    California allocates vastly more water than supplies allow, study shows

    By Matt Weiser The Sacramento Bee Published: Tuesday, Aug. 19, 2014 – 12:16 pm

    The state of California has handed out five times more water rights than nature can deliver, a new study by University of California researchers shows. California’s total freshwater runoff in an average year is about 70 million acre-feet, according to the study. But the state has handed out junior water rights totaling 370 million acre-feet. One acre-foot is enough to meet the needs of two average households for a year. The rivers under the most strain, the research indicates, are virtually all that drain into the Central Valley, including the Sacramento, Feather, Yuba, American, Mokelumne, Stanislaus, Tuolumne, Merced, Kings and San Joaquin rivers. Others near the top include the Salinas, Santa Clara, Santa Ana and Santa Ynez rivers. “It seems clear that in a lot of these cases, we’ve promised a lot more water than what’s available,” said Ted Grantham, the study’s lead author, who conducted the research as part of postdoctoral studies at UC Davis. “There’s never going to be enough water to meet all of these demands.”

    World’s Largest Dam Removal Unleashes U.S. River After Century of Electric Production

    As Washington State’s Elwha River runs free, a habitat for fish and wildlife is restored.

    Today, on a remote stretch of the Elwha River in northwestern Washington state, a demolition crew hired by the National Park Service plans to detonate a battery of explosives within the remaining section of the Glines Canyon Dam. If all goes well, the blasts will destroy the last 30 feet of the 210-foot-high dam and will signal the culmination of the largest dam-removal project in the world.  In Asia, Africa, and South America, large hydroelectric dams are still being built, as they once were in the United States, to power economic development, with the added argument now that the electricity they provide is free of greenhouse gas emissions. But while the U.S. still benefits from the large dams it built in the 20th century, there’s a growing recognition that in some cases, at least, dam building went too far—and the Elwha River is a symbol of that….

     

    California Adaptation Forum 2014

    What do you get when you bring together local, state & federal government representatives; academics; nonprofit practitioners; and private sector adaptation specialists? A lot of conversations, sharing lessons learned, ideas for future collaboration, and new friends. Last week’s California Adaptation Forum (#CAF14) brought together about 800 people to talk about climate adaptation and resilience. With breakout sessions and presentations focusing on everything from technical guidance on developing sea level rise projections to discussions on community engagement to determining success (or progress) in adaptation, the conference touched on all facets of building resilience to climate change. ASAP (American Society of Adaptation Professionals) was proud to sponsor this event and play a small part in making it a success. Having this much energy and excitement (more people attended CAF14 than last year’s National Adaptation Forum) at a regional adaptation event bodes very well for the progress of the field a whole. Congratulations to all the ASAP members (new and old), the Local Government Commission, and thanks to The Kresge Foundation and all the other sponsors who made this event a success.

    Scientists Invent a Way to Generate Electricity From Your Home’s Windows

    August 20, 2014 By Todd Woody

    Forget putting solar panels on your roof—in the near future, you may be generating electricity from windows, skylights, or even your iPhone. Researchers at Michigan State University have created a transparent photovoltaic material that can be placed over glass or any other clear surface. It’s not a new idea. Captivated by the notion of transforming glass-walled skyscrapers into giant solar power stations, scientists have spent years tinkering with solar films that can generate electricity. The problem? Most of those materials carry a colored tint, which would make working in a building with such solar windows “like working in a disco,” in the words of Richard Lunt, an assistant professor of chemical engineering and materials science at Michigan State. The breakthrough made by researchers led by Lunt was to create a material that is truly see-through. How? The luminescent solar concentrator they developed is composed of organic molecules that absorb wavelengths of sunshine invisible to human eyes, so the device could be made completely transparent. That collected sunlight is then shuttled to the edges of the plastic-like material, where it strikes thin strips of photovoltaic cells to generate electricity….

    California Is ‘Woefully Unprepared’ For Sea Level Rise, Says A New Report

    by Jeff Spross Posted on August 21, 2014

    California likely faces three feet of sea level rise by the end of the century, along with billions in damage to its economy, according to a report from the state’s legislature. The report, picked up by the San Francisco Examiner, was recently released by the Assembly Select Committee on Sea Level Rise and the California Economy. This committee held a string of hearings around the state to collect testimony from scientists and industry leaders on just what the state can expect from sea level rise, and what the consequences could be for its economy and infrastructure In particular, the report highlighted data from the United States’ oldest operating sea level gauge, which sits at Fort Point in the San Francisco Bay. It shows a seven-inch rise in the local sea level over the last one hunted years. The report then pointed to a 2012 analysis by the National Research Council, which said California should prepare for another three feet of sea level rise by 2100 — and that low-lying areas such as the San Francisco International Airport could start flooding within decades. Sea level rise can in fact occur at different speeds from region to region, and California in particular faces a faster pace than surrounding states. That’s because of likely higher local sea levels driven by El Niño climate patterns, and because portions of the state south of Cape Mendocino are subsiding thanks to tectonic plate movement. The Select Committee’s report pointed to storms and king tides that have flooded the Bay Area in recent years as the kind of events that can be exacerbated by sea level rise, and which herald the “new norm” for the state. Flooding could also bring salt water from the ocean into coastal aquifers, contaminating the state’s supply of drinking water, and coastal erosion could do away with some of the natural buffers that protect coastal communities…..

    Mideast Water Wars: In Iraq, A Battle for Control of Water

    Conflicts over water have long haunted the Middle East. Yet in the current fighting in Iraq, the major dams on the Tigris and Euphrates rivers are seen not just as strategic targets but as powerful weapons of war.

    by fred pearce 25 Aug 2014 e369Yale
    There is a water war going on in the Middle East this summer. Behind the headline stories of brutal slaughter as Sunni militants carve out a religious state covering Iraq and Syria, there lies a battle for the water supplies that sustain these desert nations.Blood is being spilled to capture the giant dams that control the region’s two great rivers, the Tigris and Euphrates. These structures hold back vast volumes of water. With their engineers fleeing as the Islamic State (ISIS) advances, the danger is that the result could be catastrophe — either deliberate or accidental. “Managing water works along the Tigris and Euphrates requires a highly specialized skill set, but there is no indication that the Islamic State possesses it,” says Russell Sticklor, a water researcher for the CGIAR, a global agricultural research partnership, who has followed events closely. The stakes are especially high since the Islamic State’s capture earlier this month of the structurally unstable Mosul Dam on the Tigris, which Iraqi and Kurdish forces, supported by U.S. airstrikes, succeeded in retaking last week. Without constant repair work, say engineers, the Mosul Dam could collapse and send a wall of water downstream, killing tens of thousands of people. Fights over water have pervaded the Middle East for a long time now. Water matters at least as much as land. It is at the heart of the siege of Gaza – the River Jordan is the big prize for Israel and the Palestinians. And over the years, water has brought Iraq, Syria and Turkey close to war over their shared rivers, the Euphrates and Tigris….

     

     

    6 Ways The Washington Post Could Show It’s Serious About Climate Change

    by Joe Romm Posted on August 27, 2014 at 9:10 am

    Cheers to the Washington Post for (finally) taking human-caused climate change seriously enough to launch a series of editorials demanding a change in both dialogue and action. Jeers for suggesting the paper will now be “more inclined to take op-eds that challenge” their view that climate science is real and that the threat posed by it is “existential.”  The Post’s first editorial in the series this week was about “The country’s sinking debate over global warming.” It begins by stating “the national debate on climate change has devolved.” As the paper’s editorial board explains, it’s devolved from serious talk by both parties before Obama’s election into inaction because “a faction that rejects the science of global warming dragged the GOP into irresponsible head-in-the-sand-ism.”

    Editorial page editor Fred Hiatt explained to Media Matters why the Post took the unusual step of committing to a week of editorials on climate change: “Over the long run it is an existential threat to the planet, I believe that, so you don’t get much bigger than that.” Precisely.

    In the spirit of these statements by the paper, here are six ways the Washington Post could show that it truly gets that climate change is an “existential threat.”

     

    1. Fact-check op-eds on climate
    2. Stop printing comments and letters from climate science deniers
    3. End false balance
    4. Restore coverage on climate change
    5. Put Juliet Eilperin (and/or another top climate reporter) back on the climate beat
    6. Bring on a full-time science blogger

     

     

     

     

     

    CHART: How Many Birds Are Killed By Wind, Solar, Oil, And Coal?

    by Emily Atkin Posted on August 25, 2014 at 4:01 pm

    In response to growing accusations from both conservationists and conservatives that renewable energy sources like solar and wind kill too many birds, U.S. News and World Report has compiled data on which energy industries are responsible for the most bird deaths every year.

    For each power source — wind, solar, oil and gas, nuclear, and coal — the data on bird deaths is gathered from different advocacy and industry groups, academic institutions, and government sources. Because estimates vary so widely on solar, wind, and oil, U.S. News included both low-range and high-range estimates for how many birds are killed by those electricity sources. Either way, the results show that even with high-range estimates for renewables compared to low-range estimates for fossil fuels, fossil fuels are responsible for far more bird fatalities than solar or wind. Note the chart below:

    A U.S. News and World Report chart shows estimates of how many birds are killed each year by different fuel sources. CREDIT: U.S. News & World Report

    The results should be taken with a grain of salt. As U.S. News noted, each study used a different methodology to come up with their numbers. “There’s no standardized way of doing it that everyone can agree to,” Garry George, the renewable energy director for Audubon California, told the magazine.

    In addition, some of the research used is outdated, and does not take into account that renewable power stands to increase in the United States. For example, the study used to estimate bird deaths from United States wind power was from 2009, and wind power has increased substantially in the United States since then. According to the American Wind Energy Association, total installed wind capacity in the U.S. was approximately 35,000 megawatts — a number that has increased to about 61,000 for 2014. Those numbers stand to increase as well, as more than 12,000 megawatts of wind capacity were currently under construction at the end of 2013, according to AWEA. The research also varies by source. Both the low and high estimates of wind power bird deaths came from a peer-reviewed study in the journal Biological Conservation, and was essentially a round-up of all available data peer-reviewed studies on the matter done by other scientists. For oil and gas, both the low and high estimates came from a Bureau of Land Management memo from 2012. The low estimate for bird deaths from solar power comes from the solar company BrightSource, which was recently accused by the Center for Biological Diversity of operating a solar farm that kills as many as 28,000 birds a year. The high estimate comes from the Center for Biological Diversity, whose estimate is just from that one solar farm in California. Bird deaths from solar farms have been estimated to be relatively low, though — a U.S. Fish and Wildlife study earlier this year found only 233 bird deaths at three different solar farms in California over the course of two years. As for coal, those bird death numbers came from a peer-reviewed study in the journal Renewable Energy. That estimate had a more sweeping methodology, though, with the study’s author including everything from coal mining to production — and bird deaths from climate change that coal emissions produce. Together, that amounted to about five birds per gigawatt-hour of energy produced by coal, almost 8 million per year. Either way, U.S. News notes that none of these numbers hold a candle to cats, which are estimated to kill 1.4 to 3.7 billion birds every year.

    UN seeks ‘Malala’ on climate change

    29 August 2014 Last updated at 01:06 ET

    Five hundred people are to learn if they have won the chance to vent their frustration at world leaders over the stalemate on climate policy. They applied to address more than 100 heads of state and government at next month’s UN climate summit in New York. Many of the candidates are established climate campaigners; they span 115 countries and include victims of natural disasters like Typhoon Haiyan. Just one winner will be chosen to speak at the plenary session. The rules stipulate that it must be a woman under 30 – which the organisers say will give a voice to the next generation. They maintain that the majority of the poorest in society are women, so they are most likely to suffer worst from climate change.
    The UN describes this as its first open competition to select members of the public to address world leaders. It attracted 544 applicants to email mini-videos urging elected leaders to cut the emissions of CO2 that are driving climate change and ocean acidification. The organisers are hoping the chosen one will electrify the conference as Pakistani schoolgirl Malala Yousafzai did when addressing the UN in 2013 as part of her campaign to ensure free compulsory education for every child.

    Malala had survived being shot in the head the previous year by Taliban gunmen because of her campaign for girls’ rights….

     

    Using the Genes of Israeli Wheat To Fight Climate Change

    A New Technology Extracts Useful Features of Wild Plants

    Searching For Good Genes: Tamar Krugman, the curator of the Wild Cereal Gene Bank in Haifa, is using the genes of wild wheat to breed a variety that is resistant to drought. courtesy of Tamar Krugman

    By Richard Blaustein Published August 20, 2014.

    Climate change and population growth have agricultural experts throughout the world increasingly worried. In addition to the usual battles against pests and diseases, poor countries now face threats of food shortages, price spikes and the political instability those conditions can cause. Since the amount of land set aside for agriculture is limited, researchers are therefore eager to find new ways to boost yield, keeping prices down. And as part of that quest, scientists are increasingly turning to wild, non-domesticated wheat to search for useful genes that can be bred into commercial grain. Israel is a center for this new technology. Despite its small size, Israel is home to many genetically diverse populations of wild plants. Wild relatives of crop plants are especially important because they contain genes that make them particularly well-suited to differing ecological settings; they are also more resistant to some diseases and grow in a variety of soil types. The genes that allow this flexibility were often lost during domestication, when genetic diversity was sacrificed so that plants cultivated for farming could take on standardized forms. Of the Israeli wild crops, wild emmer wheat, the progenitor of all domesticated wheat, is of particular interest because Israel is thought to be a secondary site (after Turkey) of wheat domestication: This is where wild emmer populations once mixed with domesticated strains. In addition, Israel is a hotspot of genetic diversity because four large regional botanic zones — the Mediterranean, the Great Rift Valley, the Saharo-Arabian desert and the Irano-Turanian ecoregions — converge here. These tracts support wild wheat populations that have adapted genetically to various ecological conditions, such as different soils and rainfall levels. By obtaining samples from various wild populations, plant scientists can access these wild plant genes and transfer them to crops of the same or even different species.

    Today, Israel has repositories for preserving this wild wheat, such as the Israeli Department of Agriculture-funded Israel Plant Gene Bank, which stores wild relatives of crop along with thousands of non-wild samples. Another major repository for wild wheat is the Wild Cereal Gene Bank, which is housed at the University of Haifa’s Institute of Evolution and contains more than 3000 wild wheat samples collected mostly in Israel. Jorge Dubcovsky, a plant geneticist at the University of California, Davis, and the Institute of Evolution recently collaborated in the discovery of a high protein content gene. Dubcovsky used wild wheat from Israel to search for the gene, which can be bred into commercial wheat, producing a nutrient-enhanced cereal that could address serious protein deficiencies and improve infant nutrition in the developing world….

    Are environmental and social problems such as global warming and poverty the result of inadequate governmental regulations or does the burden fall on our failure as consumers to make better consumption choices? According to a new study, responsible consumption shifts the burden for solving global problems from governments to consumers and ultimately benefits corporations more than society.

    Why major cow milk allergen is actually allergenic

    Posted: 22 Aug 2014 05:39 AM PDT

    Cow milk allergy occurs in children and in adults. Scientists have investigated what actually makes the milk allergenic. A specific protein in milk known as beta-lactoglobulin is able to initiate an allergy only when being devoid of iron. Loaded with iron, the protein is harmless. The scientists discovered the same mechanism recently with regard to birch pollen allergy.

    What species is this famous bird and why was she famous?


    ANSWER: Martha was a Passenger pigeon. She was the last of her species and a motivation for the U.S. to pass the first federal law protecting wildlife and much later the Endangered Species Act.


    SOURCE: Lone Passenger Pigeon Escapes Pie Pan, Lands In Smithsonian (NPR, 06/27/14) Why the obsession with this one bird? James says a lot of animals have gone extinct, but it’s rare to be able to go to the zoo and look the last one in the eyes. http://ow.ly/AN4Iv


    RELATED: The Passenger Pigeon’s Everlasting Mark: America’s Most Infamous Extinction (Huffington Post, 08/25/14) We rarely know the exact date and time an entire species goes extinct, but in the case of the passenger pigeon, we do. Martha, the very last of her species, took her final breath at the Cincinnati Zoo on September 1st 1914, marking the end of a species that was once the most abundant in North America. This was America’s first infamous extinction. http://ow.ly/AN81l

    Human contribution to glacier mass loss increasing

    August 14, 2014  University of Innsbruck

    By combining climate and glacier models, scientists headed by Ben Marzeion from the University of Innsbruck have found unambiguous evidence for anthropogenic glacier mass loss in recent decades. In a paper published in Science, the researchers report that about one quarter of the global glacier mass loss during the period of 1851 to 2010 is attributable to anthropogenic causes. The fraction of human contribution increased steadily and accelerated to almost two thirds between 1991 and 2010. The ongoing global glacier retreat causes rising sea-levels, changing seasonal water availability and increasing geo-hazards. While melting glaciers have become emblematic of anthropogenic climate change, glacier extent responds very slowly to climate changes. “Typically, it takes glaciers decades or centuries to adjust to climate changes,” says climate researcher Ben Marzeion from the Institute of Meteorology and Geophysics of the University of Innsbruck. The global retreat of glaciers observed today started around the middle of the 19th century at the end of the Little Ice Age. Glaciers respond both to naturally caused climate change of past centuries, for example solar variability, and to anthropogenic changes. The real extent of human contribution to glacier mass loss has been unclear until now….

    Helping farmers adapt to changing growing conditions

    August 11, 2014 South Dakota State University

    Two new online decision-making tools are available to farmers through the U.S. Department of Agriculture’s Useful to Usable, or U2U, research project, according to state climatologist and South Dakota State University associate professor Dennis Todey. The project is funded through the Agriculture and Foods Research Initiative. Corn Growing Degree Days, or GDDs, will show producers how their crops are developing in lieu of this year’s planting delays and a cool summer, explained Todey, who is the South Dakota U2U project director. GDDs are a measure of heat accumulation used to predict plant development rates. Farmers can choose their location, when the corn was planted and the number of days it takes to reach maturity. The program then assesses current development compared to a 30-year average and projects tasseling and maturity dates, according to Todey. The farmer can then compare that with when the first freeze has occurred during any of the last 30 years. A second tool, the Climate Patterns Viewer, allows farmers to examine the impact global climate patterns, such as El Niño Southern Oscillation and the Arctic Oscillation, have had on the Corn Belt.

    “This is very timely, since we’re looking at a pending El Niño,” he added. Farmers can track month by month how these oscillations have influenced temperatures, precipitation and subsequently crop yields.These and other online tools can be found by going to the U2U website at http://www.agclimate4u.org and clicking on the “Decision Dashboard” tab. Farmers are producing crops under more variable conditions, so these tools can be critical to both food safety and the farmers’ economic survival, Todey explained. Two additional tools are under development — one looking at the impact of inseason nitrogen application and another to help farmers decide whether to invest in an irrigation system. “The goal of U2U is to develop a dashboard of tools people can use for decision-making not only within the season but also when looking ahead at multiple seasons,” said Todey. The project, which is headed by Purdue University, involves researchers from 10 land-grant universities in the Corn Belt. “U2U capitalizes on the work scientists have been doing on longer-term practices that are better for sustainable corn production,” Todey said. Teams of agronomists, sociologists, climatologists and environmental and soil scientists are examining all aspects of the corn production system.

    California Takes Action on Climate Resiliency

    August 14, 2014 Alex Leumer, The Nature Conservancy, Policy Associate, California Climate Change Program

    California is taking action on climate resiliency and nature is playing a key role.  The California Natural Resources Agency recently released the 2014 Safeguarding California Plan (SCP). This plan provides policy guidance for state decision makers, to reduce impacts and prepare for climate risks. The SCP, which updates the 2009 California Climate Adaptation Strategy, highlights climate risks in nine sectors in California, discusses progress to date, and makes sector-specific recommendations. The Nature Conservancy along with nineteen other environmental and public health organizations submitted comments to the Resources Agency and are pleased to see that many of our recommendations have been incorporated in the final plan. Overall, the Plan acknowledges the important role nature plays in reducing climate risks and enhancing resilience. Highlights from the Plan that reflect our comments include:

    • “State agencies should identify climate risks to existing and new infrastructure projects. For new projects, climate risks should be considered in the planning, siting, design, construction, and maintenance of infrastructure projects.
    • The 2009 CAS recommended that all new development “consider project alternatives that avoid significant new development in areas that cannot be adequately protected (planning, permitting, development, and building) from flooding, wildfire and erosion due to climate change.” To see this implemented, the state needs to require that climate risk considerations be incorporated into state infrastructure planning.
    • “The state should develop guidelines for state agencies to follow as they incorporate climate considerations into all policies, planning, and investments.
    • “Achieve Multiple Benefits from Efforts to Reduce Climate Risks and Prioritize Green Infrastructure Solutions: actions that reduce climate risks across multiple sectors and actions that address multiple climate risks should be prioritized. …One opportunity to achieve broad environmental benefits is through the use of natural infrastructure solutions to mitigate climate risk. Restoration and conservation of natural systems such as forests, grasslands and shrublands, agricultural lands, and wetlands can provide more resilient natural systems that also offer protection from climate impacts.
    • “Develop Metrics and Indicators to Track Progress on Efforts to Reduce Climate Risk
      The Governor’s Office of Planning and Research is also leading an effort develop an integrated set of indicators to help track progress on the state’s efforts to reduce GHG emissions and build climate resilience.”

    This is an important step to making California more resilient to climate change. However, currently there is no law mandating implementation of any of the recommendations.  We look forward to working with the state and the legislature to implement the strategies laid out in the SCP.

    Ecosystems can have their fish, and we can eat them too

    Phys.Org Aug 1, 2014

    Tighter bag limits for fishermen have been identified as an important key to ocean ecosystem conservation Researchers at The University of Queensland’s Global Change Institute have found that marine reserves can protect small areas, but it is often more effective to limit fishing across the seascape. Dr Christopher Brown said the research, published today in Frontiers in Ecology and the Environment, found more emphasis was needed on a mixed management approach. “Marine ecosystems are intrinsically interlinked so protecting a small area of the ocean can actually lead to over-fishing in another place,” he said. …

     

    Effect of habitat fragmentation on forest carbon cycle revealed by study

    Posted: 12 Aug 2014 09:24 AM PDT

    Drier conditions at the edges of forest patches slow down the decay of dead wood and significantly alter the cycling of carbon and nutrients in woodland ecosystems, according to a new study. It has long been known that so-called ‘edge effects’ influence temperature and moisture (the ‘microclimate’) in woodlands, but the influence on the carbon cycle is largely unknown.

     

    Could urbanization, biodiversity be compatible?

    Posted: 14 Aug 2014 09:38 AM PDT

    More than 900 species of wild bees are found in France, but many of them – such as bumblebees – are in decline. Researchers have carried out the first exhaustive study in Europe to evaluate the impact of urbanization on the wild bee community.. They studied 24 more or less urbanized sites in and around Lyon and recorded 291 different bee species. Although bee abundance decreased with an increasing level of urbanization, the number of species present was at its peak in periurban areas, and 60 species — a considerable number — were found at the most urban site. These findings are published in the open-access journal PLOS ONE on 13 August 2014.

     

     

    Taking Up Arms Where Birds Feast on Buffet of Salmon

    By FELICITY BARRINGER AUG. 15, 2014 NYTIMES

    Scientists studying the cormorant colony in Oregon are looking for the best way to remove most of the birds.

    ASTORIA, Ore. — The salmon here in the Columbia River, nearly driven to extinction by hydroelectric dams a quarter century ago, have been increasing in number — a fact not lost on the birds that like to eat them. These now flock by the thousands each spring to the river’s mouth, where the salmon have their young, and gorge at leisure. As a result, those charged with nursing the salmon back to robust health have a new plan to protect them: shoot the birds. Joyce Casey, chief of the environmental resources branch at the Army Corps of Engineers office in Portland, said that for young salmon headed seaward, the hungry horde of about 30,000 double-crested cormorants on East Sand Island has posed a risk no less serious than that posed by some of the dams her agency built.

    Butch Smith, a fisherman, said that killing thousands of the birds “is the one thing out of anything else we can do to recover salmon fastest.” But Stan Senner of the National Audubon Society argues that to kill off some of the cormorant colony here, which makes up one-quarter of the birds’ western population, “is an extreme measure, totally inappropriate.” …

    Humpback Whales Return To New York As Atlantic Offshore Drilling Moves Forward

    August 12, 2014

    The Guardian is reporting a summer “wildlife bonanza” in the waters surrounding New York City, brought on in part by an increasingly successful cleanup of the Hudson River, which flows into New York harbor. The surge in whale and other marine life populations comes less than a month after the Obama administration approved the use of seismic airguns in the waters of New Jersey down to Florida to explore the seabed for oil and gas. The airguns use dynamite-like blasts to produce sound waves 100,000 times louder than a jet engine underwater, sometimes killing and injuring marine mammals.

    Though the seismic testing is not happening in New York, the sound waves from the cannons are known to travel hundreds of miles, potentially affecting those humpbacks and other marine life in the area. For now though, populations are surging. Former New York Aquarium Curator Paul Sieswerda, who now heads up the marine wildlife tracking and research group Gotham Whale, told the Guardian that he’s already seen 29 humpback whales in New York waters from the spring to July. That’s compared to 43 whale sightings for the entire 2013 feeding season — which lasts from spring until winter — 25 sightings in the 2010 season and just five sightings in 2011, the report said.

     

     

    Rare baby bird found in Petaluma is no bigger than a cottonball

    Posted on Tuesday, August 12


    Petaluma resident Dione Rochelle snapped a picture of the baby bird in her hand

    The International Bird Rescue is caring for an orphaned baby bird that’s so tiny it’s no bigger than a cotton-ball. This baby black rail, a threatened shorebird that’s rarely seen, was found Wednesday evening by a Petaluma couple on a stroll near Shollenberger Park. “He was just walking down the middle of the path like he owned the place. He looked like a pom-pom,” said Dione Rochelle. “He was going pretty fast. We stepped back thinking there was a mother or other babies. ” A hiker walking by told Dione and her husband Peter that he had seen the same little bird running around an hour before.

    Kurtis Alexander, Wednesday, August 13, 2014

    Foster City is the latest community to deal with a stinky, somewhat unwieldy die-off of thousands of anchovies. Public works crews in the Peninsula city spent the past few days cleaning offshore waters and beaches of dead fish, officials said Wednesday. Reports of the lifeless anchovies at and around Gull and Marlin beaches on San Francisco Bay began coming in over the weekend. “We’ve got as many as we could off the beach,” said Mike McElligott, public works maintenance superintendent, who noted Wednesday that a fishy stench remains. The mess is believed to be caused by the same thing that prompted other recent die-offs along the coast: too many anchovies using too much oxygen in the water and suffocating themselves.

     

     

     

     

    Helping farmers adapt to changing growing conditions

    August 11, 2014 South Dakota State University

    Two new online decision-making tools are available to farmers through the U.S. Department of Agriculture’s Useful to Usable, or U2U, research project, according to state climatologist and South Dakota State University associate professor Dennis Todey. The project is funded through the Agriculture and Foods Research Initiative. Corn Growing Degree Days, or GDDs, will show producers how their crops are developing in lieu of this year’s planting delays and a cool summer, explained Todey, who is the South Dakota U2U project director. GDDs are a measure of heat accumulation used to predict plant development rates. Farmers can choose their location, when the corn was planted and the number of days it takes to reach maturity. The program then assesses current development compared to a 30-year average and projects tasseling and maturity dates, according to Todey. The farmer can then compare that with when the first freeze has occurred during any of the last 30 years. A second tool, the Climate Patterns Viewer, allows farmers to examine the impact global climate patterns, such as El Niño Southern Oscillation and the Arctic Oscillation, have had on the Corn Belt.

    “This is very timely, since we’re looking at a pending El Niño,” he added. Farmers can track month by month how these oscillations have influenced temperatures, precipitation and subsequently crop yields.These and other online tools can be found by going to the U2U website at http://www.agclimate4u.org and clicking on the “Decision Dashboard” tab. Farmers are producing crops under more variable conditions, so these tools can be critical to both food safety and the farmers’ economic survival, Todey explained. Two additional tools are under development — one looking at the impact of inseason nitrogen application and another to help farmers decide whether to invest in an irrigation system. “The goal of U2U is to develop a dashboard of tools people can use for decision-making not only within the season but also when looking ahead at multiple seasons,” said Todey. The project, which is headed by Purdue University, involves researchers from 10 land-grant universities in the Corn Belt. “U2U capitalizes on the work scientists have been doing on longer-term practices that are better for sustainable corn production,” Todey said. Teams of agronomists, sociologists, climatologists and environmental and soil scientists are examining all aspects of the corn production system.

     

    Climate change, predators, and trickle down effects on ecosystems

    Posted: 11 Aug 2014 03:03 PM PDT

    Predators play important roles in maintaining diverse and stable ecosystems. Climate change can push species to move in order to stay in their climatic comfort zones, potentially altering where species live and how they interact, which could fundamentally transform current ecosystems. A symposium focusing on climate’s effects on predators — causing cascading effects on whole ecosystems — will take place on Tuesday, August 12th during the Ecological Society of America’s 99th Annual Meeting, held this year in Sacramento, California. There will be “winners” and “losers” as species adapt to a changing climate. Ecologists are just beginning to understand why different competitors may be favored by climate change and how consumer-resource interactions are modified. Impacts on one species can affect many organisms in an ecosystem. Because predator species are animals that survive by preying on other organisms, they send ripples throughout the food web, regulating the effects other animals have on that ecosystem. This cause and effect process is called a “trophic cascade,” or the progression of direct and indirect effects predators have across lower levels in a food chain. Sea otter populations provide a historical example of this phenomenon. The fur trade spanning the late 1700s to early 1900s decimated their numbers across their range, from Alaska to Baja California, Mexico. Populations went from an estimated several hundred-thousand to more than a million …. Today, there are estimated to be just over 106,000 worldwide, with just under 3,000 in California. Now sea otters and other important predator species face the challenges of a changing climate….

    Without sea otters, the undersea sea urchins they prey on would devour the kelp forests, resulting in dense areas called sea urchin barrens that have lower biodiversity due to the loss of kelp that provide 3-dimensional habitat and a food source for many species. Researchers found that when sea otters arrive in an area from which they have been absent, they begin feasting on urchins. As a result, the kelp forest begins to grow back, changing the structure of kelp forest communities. Many fish, marine mammals and birds are also found in kelp forest communities, including rockfish, seals, sea lions, whales, gulls, terns, snowy egrets as well as some shore birds. Otters might also offer a defense against climate change because healthy kelp forests can grow rapidly and store large amounts of carbon. Dr. Martone’s analyses of the effects of sea otters on kelp forest ecosystems can help shape predictions of how climate change and trophic cascades, in concert with other drivers, affect coastal ecosystems. The ecological impacts of a changing climate are evident, from terrestrial polar regions to tropical marine environments. Ecologists’ research into the tropic cascading effects of predators will assist decision makers by providing important scientific findings to prepare for the impacts of climate change occurring now and into the future. Speakers for the symposia include marine, freshwater and terrestrial experimental ecologists who will present their research and offer insights from different approaches used to studying consumer-resource interactions….

     

    Antarctica may lift sea level faster in threat to megacities

    Antarctica glaciers melting because of global warming may push up sea levels faster than previously believed, potentially threatening megacities including New York and Shanghai, researchers in Germany said. Antarctica’s ice discharge may raise sea levels as much as 37 centimeters (14.6 inches) this century if the output of greenhouse gases continues to grow, according to a study led by the Potsdam Institute for Climate Impact Research. The increase may be as little as 1 centimeter, they said. “This is a big range, which is exactly why we call it a risk,” Anders Levermann, the study’s lead author, said in a statement. “Science needs to be clear about the uncertainty so that decision-makers at the coast and in coastal megacities can consider the implications in their planning processes.”

    Heavy rain and floods: The ‘new normal’ with climate change?

    As people clean up after torrential rains and heavy flooding in cities in the Midwest and along the Atlantic Coast, the events highlight what many climate researchers say is a new “normal” for severe rainfall in the US.  Quite apart from what long-term changes in precipitation say about global warming, these events also provide a reality check on the ability of urban areas to cope with flooding from intense downpours in a warming climate. They “definitely can tell us a lot about where our vulnerabilities are and what types of things might be on the checklist for fixing,” says Joe Casola, staff scientist with the Center for Climate and Energy Solutions in Arlington, Va.

    Human contribution to glacier mass loss increasing

    August 14, 2014 University of Innsbruck

    By combining climate and glacier models, scientists headed by Ben Marzeion from the University of Innsbruck have found unambiguous evidence for anthropogenic glacier mass loss in recent decades. In a paper published in Science, the researchers report that about one quarter of the global glacier mass loss during the period of 1851 to 2010 is attributable to anthropogenic causes. The fraction of human contribution increased steadily and accelerated to almost two thirds between 1991 and 2010. The ongoing global glacier retreat causes rising sea-levels, changing seasonal water availability and increasing geo-hazards. While melting glaciers have become emblematic of anthropogenic climate change, glacier extent responds very slowly to climate changes. “Typically, it takes glaciers decades or centuries to adjust to climate changes,” says climate researcher Ben Marzeion from the Institute of Meteorology and Geophysics of the University of Innsbruck. The global retreat of glaciers observed today started around the middle of the 19th century at the end of the Little Ice Age. Glaciers respond both to naturally caused climate change of past centuries, for example solar variability, and to anthropogenic changes. The real extent of human contribution to glacier mass loss has been unclear until now….

    Ocean Acidification: Tailpipes, smokestacks outproduce volcanoes

    Ken Caldeira SF Chronicle Opinion Updated 7:51 pm, Friday, August 15, 2014

    The sun sets over the Pacific as powerful waves crash on the rocky shore. We are witnessing a scene that could have been seen billions of years ago. Except now, emissions from our tailpipes and smokestacks are making it more and more likely that those waves crashing against the rocks will be corrosive, dissolving seashells. This process is known as “ocean acidification.”

    Dick Feely and his colleagues at Pacific Marine Environmental Laboratory in Seattle have been observing waters along the West Coast, and have seen corrosive water along the shore in Northern California. My friend Tessa Hill, working at the Bodega Marine Laboratory of UC Davis, has been looking into the effects ocean acidification might have on the oyster farms in Tomales Bay – and the news is not good. It looks as if ocean acidification can harm oysters, especially in their larval stages. My research group has been looking into effects of ocean acidification in Australia’s Great Barrier Reef. One reef we studied is growing 40 percent more slowly than it was just a few decades ago. We project that all of the coral reefs of the world may be dissolving within several decades, if current patterns of carbon dioxide emissions continue.
    Carbon dioxide in the atmosphere acts as a greenhouse gas, causing the Earth to warm. But most of the carbon dioxide we emit to the atmosphere eventually will be absorbed by the ocean. And once in the oceans, that carbon dioxide becomes carbonic acid, where it can attack the shells and skeletons of marine organisms. Even if this carbonic acid is not in high enough concentrations to dissolve a seashell, it can make it harder for that clam or sea urchin or oyster to build its shell. And if it is working harder to build its shell, it will have less energy left over to look for food, reproduce or defend itself from predators….

    Loss of eastern hemlock affects peak flows after extreme storm events

    Posted: 12 Aug 2014 09:23 AM PDT

    The loss of eastern hemlock could affect water yield and storm flow from forest watersheds in the southern Appalachians, according to a new study. Because of its dense evergreen foliage, eastern hemlock plays an important role in the water cycle of southern Appalachian forests, regulating stream flow year round. Although eastern hemlock rarely dominates the region’s forests, the tree is considered a foundation species in the streamside areas called riparian zones….

     

    Climate change reflected in altered Missouri River flow, USGS report says

    By Maya Srikrishnan Los Angeles Times August 17, 2018

    • The Missouri River’s altered flow causes water shortages in Montana and Wyoming and flooding in the Dakotas.
    • Climate change is altering the Missouri River stream flow, wreaking havoc on farmland, new report says Montana farmer Rocky Norby has worked the land along the Missouri River for more than 20 years, coaxing sugar beets and malted barley out of the arid ground.

    “Every year it gets worse,” he said. “There’s not enough water to get through our pumps.” Last month, he said, he spent more than $10,000 trying to remove the sand from his clogged irrigation system.

    The Missouri River’s stream flow has changed significantly over the last 50 years, leading to serious water shortages in Montana and Wyoming and flooding in the Dakotas, according to a U.S. Geological Survey report released last month. “We’ve all had to make some adjustments,” said Buzz Mattelin, another Montana farmer who irrigates with water from the Missouri. “We’ve had to spend more money and learn how to adapt.”

    In the Dakotas, flooding is more common, leaving fields too muddy to plant or harvest crops.This dichotomy isn’t necessarily a surprise. “Climate change models predict that where it is wet, it will get wetter, and where it is dry, it will get drier,” said Matt Rice, a program director at American Rivers, a nonprofit conservation organization. The mighty Missouri River begins in the Rocky Mountains of western Montana, flowing east and south for more than 2,300 miles before entering the Mississippi River north of St. Louis. The Missouri and its tributaries provide hydropower as well as water for agriculture, energy, recreation and municipalities in several states, including Montana, Nebraska, Wyoming and the Dakotas. Climate shifts may be causing the disparate changes in the Missouri River Basin, the USGS report says. The scientists noted that higher stream flow in the Dakotas had occurred even as water use increased. In addition, they said, lower stream flow in some areas could be related in part to groundwater pumping. “Understanding stream flow throughout the watershed can help guide management of these critical water resources,” said USGS hydrologist Parker Norton, lead author of the report that focuses on stream flow. The study is part of his doctoral research, which will analyze precipitation patterns, temperatures and their effects…

     

     

    New analysis links tree height to climate

    August 14, 2014 University of Wisconsin-Madison

    What limits the height of trees? Is it the fraction of their photosynthetic energy they devote to productive new leaves? Or is it their ability to hoist water hundreds of feet into the air, supplying the green, solar-powered sugar factories in those leaves? A new paper attempts to resolve a debate as to which factors actually set maximum tree height, and how their relative importance varies in different parts of the world….One of the species under study, Eucalyptus regnans — called mountain ash in Australia, but distinct from the smaller and unrelated mountain ash found in the U.S. — is the tallest flowering tree in the world. In Tasmania, an especially rainy part of southern Australia, the tallest living E. regnans is 330 feet tall. (The tallest tree in the world is a coastal redwood in northern California that soars 380 feet above the ground.)

    Southern Victoria, Tasmania and northern California all share high rainfall, high humidity and low evaporation rates, underlining the importance of moisture supply to ultra-tall trees. But the new study by Givnish, Graham Farquhar of the Australian National University and others shows that rainfall alone cannot explain maximum tree height.

    A second factor, evaporative demand, helps determine how far a given amount of rainfall will go toward meeting a tree’s demands. Warm, dry and sunny conditions cause faster evaporation from leaves, and Givnish and his colleagues found a tight relationship between maximum tree height in old stands in Australia and the ratio of annual rainfall to evaporation. As that ratio increased, so did maximum tree height.

    Other factors — like soil fertility, the frequency of wildfires and length of the growing season — also affect tree height. Tall, fast-growing trees access more sunlight and can capture more energy through photosynthesis. They are more obvious to pollinators, and have potential to outcompete other species.

    “Infrastructure” — things like wood and roots that are essential to growth but do not contribute to the production of energy through photosynthesis — affect resource allocation, and can explain the importance of the ratio of moisture supply to evaporative demand.

    “In moist areas, trees can allocate less to building roots,” Givnish says. “Other things being equal, having lower overhead should allow them to achieve greater height.

    “And plants in moist areas can achieve higher rates of photosynthesis, because they can open the stomata on their leaves that exchange gases with the atmosphere. When these trees intake more carbon dioxide, they can achieve greater height before their overhead exceeds their photosynthetic income.”…

    Higher Pacific temperatures bring monsoons to Southern California.

    August 4, 2014, 9:14 PM

    Flash floods, wilting heat and lightning on the beach. It’s monsoon season in a place that’s not supposed to have one. Changes in ocean temperature thousands of miles away have delivered Arizona-style summer weather to Southern California, driving up humidity and causing sporadic destruction. Warm equatorial water in the Pacific, from mainland Mexico to Peru, normally pumps monsoonal air up the Sea of Cortez into the Southwest, with mountains blocking it from the coastal plains of Southern California. But this year, the ocean temperatures are higher than normal, climatologists say, producing a more powerful “tropical wave” that made it all the way to the coast….

     

    Global warming woes? Tiny ants might save Earth

    Researchers say that tiny ants may save the world from global warming woes by cooling the Earth. Ronald Dorn, a geologist at Arizona State University in Tempe, who is also the lead author of the study, says that ants are altering the Earth’s environment. The researchers say that an average ant does not live even for over a year but they help to reduce tiny bits of carbon dioxide gas from the Earth’s atmosphere. An increase in ant population on the planet may help reduce global warming to a certain extent. The scientists explain that some species of ant “weather” minerals to secrete calcium carbonate, which is also known as limestone. When these tiny creatures produce limestone, the process also removes and traps small particles of carbon dioxide gas from Earth’s atmosphere. Dorn compares the process to carbon sequestration, which occurs in the planet’s oceans. The researchers say that the huge deposits of limestone in Earth’s ocean bear more carbon, than what is present in the current atmosphere.

    Over the weekend, 400,000 people in northwest Ohio were told that their tap water was no longer safe to drink, cook with or bathe in. Water at a treatment plant had tested positive for dangerously high levels of toxins. Residents were warned that microcystis, the bacteria behind the chaos, can cause skin rashes and burns, along with vomiting, diarrhea and liver problems. It’s been known to kill pets and livestock. And boiling water, officials added, only makes the problem worse. Life came, temporarily, to something of a standstill until 9 a.m. Monday when, after extra, precautionary delays, Toledo Mayor D. Michael Collins finally declared the water safe again…

     

    Farming practices and climate change at root of Toledo water pollution

    The toxins that contaminated the water supply of the city of Toledo – leaving 400,000 people without access to safe drinking water for two days – were produced by a massive algae boom. But this is not a natural disaster. Water problems in the Great Lakes – the world’s largest freshwater system – have spiked in the last three years, largely because of agricultural pollution. Toledo draws its drinking water from Lake Erie. Residents were warned not to drink the water on Saturday, after inspectors at the city’s water treatment plant detected the toxin known as microcystin. The toxin is produced by microcystis, a harmful blue-green algae; it causes skin rashes and may result in vomiting and liver damage if ingested. It has been known to kill dogs and other animals and boiling the water does not fix the problem; it only concentrates the toxin….

     

    The Threats to Our Drinking Water

    August 6, 2014 By DAVID S. BECKMAN

    Two cities now know what it’s like when the taps are shut off.

    SAN FRANCISCO — THOSE of us who live in the United States are fortunate; generally we don’t have to give a lot of thought to the safety of our tap water. This makes our collective experience with water very different from that of hundreds of millions of people across the globe who lack access to clean water. But twice this year the water supply for a major American city was interrupted for days by water pollution. In January, a chemical used in the processing of coal leaked from a ruptured storage tank into the Elk River, contaminating the water supply for about 300,000 people in and around Charleston, W.Va., the state’s capital and largest city. Then, last weekend, the water supply for over 400,000 people in Toledo, Ohio, was declared unsafe because of the presence of microcystin, a toxin released by algae blooms in nearby Lake Erie, the source of the city’s water….

     

    California Wildfires Kill More Than Trees, And That May Help Us Prevent Them In The Future


    5 August 2014 | The Hetch Hetchy watershed is 160 miles from the San Francisco Bay area, but the people of the Bay rely on this granite-surrounded water supply as their drinking source. Located in the Yosemite National Park, the Hetch Hetchy is situated along the Tuolumne River in California’s Sierra Nevada and acts as a reservoir collecting the mountain range’s melting snow. Its water travels to San Francisco through miles of pipelines and tunnels called the Hetch Hetchy Regional Water System, which supplies over 2 million people in four counties with water. Last year, the now-infamous Rim Fire burned 250,000 acres of Sierra Nevada forestland from August 17, 2013 to October 24. But something stunning happened when it moved out of Stanislaus National Forest and into Yosemite: its intensity was immediately waned. That helped save the Hetch Hetchy and San Francisco’s water supply, but the fires still cost the San Francisco Public Utilities Commission (SFPUC) $55 million in infrastructure costs. These damages – and the fact that the fire came so close to threatening its water – got the SFPUC thinking about natural losses. They wondered what the real costs of the fire were in terms of muddied water, lost pollination, dirty air, and a general loss of quality in the region – and how high could those costs could go if the winds went against them. To answer that question, they hired Earth Economics (EE), a nonprofit specializing in the economic valuation of ecosystem services to look at the cost of the Rim Fire itself – not just in terms of infrastructure, but in terms of ecosystem services….

     

    Japanese red cedars to replace Britain’s traditional oaks in fight against climate change. 

    The Telegraph, United Kingdom August 5, 2014

    Trees from America, Japan and southern Europe will be planted in Britain’s forests to avoid them shrinking by 40 per cent by 2080 because of climate change. Japanese red cedar, giant redwoods and trees from the continent will replace oaks and pines in Britain’s forests as woodlands must adapt to climate change to survive, a study suggests. Species of trees grown in the UK in the Victorian era are also set to return as foresters work to ensure Britain’s woods can survive rising temperatures, frequent droughts and diseases. Experts have warned if nothing is done to change the composition of Britain’s woodlands by 2080, forest production could decrease by more than 40 per cent as current trees struggle to survive.

    Climate change is here, it’s happening now, and for the last few decades it has been demonstrably bad news for many of Europe’s forests. An international team of researchers say in a report from the European Forest Institute that climate change is altering the environment, and it is long-lived ecosystems like forests that are particularly vulnerable to the comparatively rapid changes occurring in the climate system. The report, published in the journal Nature Climate Change, shows that damage from wind, bark beetles, and wildfires has increased significantly in Europe’s forests in recent years. Windthrow − the wind’s effect in damaging or uprooting trees − is an increasing problem….

    Drought-busting El Niño looking less likely

    Friday, August 8, 2014


    Hope of an El Niño rescuing California from its devastating drought this year appears to be just about gone. Not only have climate scientists downgraded the strength of a potential El Niño, but a report released Thursday by the U.S. Climate Prediction Center indicates that the odds of an El Niño happening at all have decreased. El Niño is a warming of the Pacific Ocean that tends to influence worldwide weather. Strong El Niños have often been associated with wet winters in Northern California, something the state could use after three straight years of below-average rainfall. Although Thursday’s climate report suggests that an El Niño is still likely this fall or winter, scientists said the chances had dropped from 80 percent in earlier assessments to 65 percent. The reason for the more pessimistic outlook, said climate scientist Michelle L’Heureux, is that warmer-than-usual surface temperatures in the equatorial Pacific measured this spring have since cooled….

    Climate change and drought in ancient times

    Posted: 11 Aug 2014 12:15 PM PDT

    The influence of climate on agriculture is believed to be a key factor in the rise and fall of societies in the Ancient Near East. Dr. Simone Riehl of Tübingen University’s Institute for Archaeological Science and the Senckenberg Center for Human Evolution and Palaeo-environment has headed an investigation into archaeological finds of grain in order to find out what influence climate had on agriculture in early farming societies. Her findings are published in this week’s PNAS — Proceedings of the National Academy of Sciences. She and her team analyzed grains of barley up to 12,000 years old from 33 locations across the Fertile Crescent to ascertain if they had had enough water while growing and ripening. Riehl found that periods of drought had had noticeable and widely differing effects on agriculture and societies in the Ancient Near East, with settlements finding a variety of ways to deal with the problem.…. They found that many settlements were affected by drought linked to major climate fluctuations. “Geographic factors and technologies introduced by humans played a big role and influenced societies’ options for development as well as their particular ways of dealing with drought,” says Riehl. Her findings indicate that harvests in coastal regions of the northern Levant were little affected by drought; but further inland, drought lead to the need for irrigation or, in extreme cases, abandonment of the settlement. The findings give archaeologists clues as to how early agricultural societies dealt with climate fluctuations and differing local environments. “They can also help evaluate current conditions in regions with a high risk of crop failures,” Riehl adds. The study is part of a German Research Foundation-backed project looking into the conditions under which Ancient Near Eastern societies rose and fell.

     

     

     

     

     

     

     

    New York: Community Risk Reduction and Resiliency Act

    Summary: The New York bill (Senate Bill 6617), called the “Community Risk Reduction and Resiliency Act” and sponsored by Democratic state Sen. Diane and Assemblyman Robert Sweeney, amends the state’s existing environmental conservation, agriculture and market, and public health laws to require consideration of the effects of climate change and extreme weather events before issuing state permits and allocating infrastructure funds (including grants to NGOs for conservation work). The purpose of the bill is to amend certain New York legislation to reflect greater awareness and preparedness for climate change associated risks such as sea level rise and flooding. The bill represents one of the first state efforts in the country to incorporate climate change preparedness into official legislation and is an optimistic indicator of growing climate change awareness. Importantly, it requires the Department of State (DOS) to work with the Department of Environmental Conservation (DEC) to develop resiliency guidance that utilizes
    natural resources and natural processes to reduce risk.

    It also reaches the local level by requiring DOS to prepare model local zoning laws that include climate risk analysis and make these laws available to municipalities. …

    Highlights:

    • Purpose: require consideration of "future physical climate risk due to sea level rise, storm surges, and flooding, based on available data predicting the likelihood of future extreme weather events , including hazard risk analysis", before issuing state permits (for design and construction of future projects) and allocating infrastructure funds.
      
    • More specifically, climate risk analysis requirement is added in the following sections:
      
      • Smart Growth Infrastructure Policy Act: criteria for financing (including grants) for construction of new or expanded  public infrastructure
      • Citing of hazard waste facilities;
      • Clean Water State Revolving Fund (a climate risk analysis must be included to be eligible for funding and is a criteria for priority ranking of projects);
      • Standards for design and construction of hazardous substance storage facilities
      • State land acquisition policy;
      • Closure of landfills;
      • Establishing standards for existing and new petroleum bulk storage facilities;
      • Applications municipalities and NGOs seeking state funds:
        • For coastal rehabilitation projects;
        • To operate and maintain public open space land conservation projects;
        • For agriculture and farmland protection (under the Agriculture and Markets Law).  

    Importantly, it would also:

    • direct the Department of State to prepare model local laws that include consideration of future physical climate risk and to make such laws available to municipalities;
    • direct the Department of Environmental Conservation to prepare guidance on the implementation of the act, including data and risk analysis tools;
    • require the Department of Environmental Conservation to adopt regulations establishing science-based state sea level rise projections.

    Status: Both houses of the New York State legislature have passed the Community Risk Reduction and Resiliency Act, but Governor Cuomo has yet to sign the bill into law. Full text is available here.

    Agreement boosts urban sustainability

    A new five-year agreement between the United Nations Global Compact and an Australian university will strengthen efforts to tackle the world’s urban challenges. Under the new agreement, the Cities Programme will aim to expand into the Asia-Pacific and double the number of signatory cities: the 86 currently participating cities range from large metropolitan capitals (Barcelona, Melbourne, Berlin, Quito) to states (Sao Paulo and Parana in Brazil, Queretaro in Mexico) and municipalities (Besiktas in Turkey, San Isidro in Argentina)….

     

     

     

     

     

    President Carter calls for carbon tax at Aspen renewable energy conference

    August 12, 2014 ASPEN, Colo. — President Jimmy Carter called a tax on carbon emissions “the only reasonable approach” to combating climate change during an appearance here Tuesday, but lamented that even piecemeal actions are unlikely to get through a divided Congress. Carter, 89, who received a lifetime achievement award on the final day of the American Renewable Energy Day summit, spoke during a luncheon attended by a number of conservationists as well as Ted Turner, T. Boone Pickens and Tom Steyer, the California billionaire pledging to devote his personal finances to political candidates willing to take action on climate change.

     

     

    $11 Billion Later, High-Speed Rail Is Inching Along

    By RON NIXON August 6, 2014 WASHINGTON — High-speed rail was supposed to be President Obama’s signature transportation project, but despite the administration spending nearly $11 billion since 2009 to develop faster passenger trains, the projects have gone mostly nowhere and the United States still lags far behind Europe and China. While Republican opposition and community protests have slowed the projects here, transportation policy experts and members of both parties also place blame for the failures on missteps by the Obama administration — which in July asked Congress for nearly $10 billion more for high-speed initiatives. Instead of putting the $11 billion directly into those projects, critics say, the administration made the mistake of parceling out the money to upgrade existing Amtrak service, which will allow trains to go no faster than 110 miles per hour. None of the money originally went to service in the Northeast Corridor, the most likely place for high-speed rail.

    Airport tests new way to avoid deadly bird strikes

    NEW YORK (AP) — When birds and planes collide, the results can be deadly. That’s why airports around the world work hard to keep birds away, even resorting to shooting or poisoning large flocks. One Ohio airport is now experimenting with a new, gentler way to avoid bird strikes: planting tall prairie grass. Heavy birds like geese — which cause the most damage to planes — are believed to avoid long grasses because they fear predators might be hiding within. So officials at Dayton International Airport are converting up to 300 acres of the airfield’s 2,200 non-aeronautical acres into prairie grass. The goal is, by the end of this year, to plant the tall grass under the takeoff and landing paths. There are more than 10,000 airplane bird strikes a year in the U.S. Most do little or no damage to the plane. The most frequent problem is damage to the engines. The FAA estimates that such damage costs the industry $950 million a year.

     

     

    Fools at the Fire

    By TIMOTHY EGAN NY Times August 7th, 2014

    In the heat, in the still gloaming, we set up camp near a snowbank across from a glacier and a symphony of waterfalls. North Cascades National Park, a few hours’ drive from Seattle, can always be counted on as a compress to the rest of the country’s fever. Then, out of the park a few days later, down the valley to the arid east, it seems as if half of Washington State is on fire. Smoke, devastation, ashen orchards of charred fruit, standing dead pines. More than 250,000 acres have burned in the largest fire in the state’s history, the Carlton Complex. About 300 homes have been destroyed. A small army of firefighters, at a cost of $50 million so far, is trying to hold the beast in the perimeter, between days when the mercury tops 100 degrees. With this kind of loss comes blame. It’s President Obama’s fault. Why? Because everything is his fault in the inland West, where ignorance rides the airwaves of talk radio. Amid the conservative cant, a great irony: People who hate government most are the loudest voices demanding government action to save their homes….

     

    Shattering Myths to Help the Climate

    Robert H. Frank AUG. 2, 2014 New York Times

    Each
    new climate-change study seems more pessimistic than the last. This May and June, for example, were the hottest ones on record for the planet. Storms and droughts occur with increasing frequency. Glaciers are rapidly retreating, portending rising seas that could eventually displace hundreds of millions of people. Effective countermeasures now could actually ward off many of these threats at relatively modest cost. Yet despite a robust scientific consensus that greenhouse gas emissions are at the root of the problem, legislation to curb them has gone nowhere in Congress. In response, President Obama has proposed stricter regulations on electric utilities, which some scientists warn may be too little, too late.

    A road map to the future of state parks

    SFGate August 3, 2014


     

    California now has a road map to the future of the state’s troubled park system. It just needs a driver.

    Parks Forward – a state-appointed blue-ribbon commission with deep talent, knowledge and connections – issued detailed draft recommendations last week for a “series of sweeping changes to ensure the long-term sustainability of California’s State Parks.” Now it’s up to Gov. Jerry Brown to find a leader who will use this new road map to guide reform in the state Department of Parks and Recreation. The former Marine major general whom the governor appointed to turn around the scandal-plagued agency in late 2012 retired in May after only 18 months on the job. An acting director from within the department is holding down the fort while waiting for the governor to make his move….

    OLYMPIA, Wash. — Billions of baby oysters in the Pacific inlets here are dying and Gov. Jay Inslee of Washington is busy spreading the bad news. “It used to be the canary in the coal mine,” Mr. Inslee said in a recent interview. “Now it’s the oyster in the half shell. You can’t overstate what this means to Washington.” Or to Mr. Inslee’s ambitions. The Democratic governor, aided by what is expected to be millions of dollars from his billionaire friend Tom Steyer, is using the story of Washington’s oysters — scientists say a rise in carbon levels has spiked the acidity of the Pacific and is killing off shellfish — to make the case for passing the most far-reaching climate change policies in the nation.

     

    California Wildfires Kill More Than Trees, And That May Help Us Prevent Them In The Future
    Kelli Barrett
    One year ago this month, the infamous Rim Fire started burning in northern California’s Sierra Nevada mountains. It raged for two full months and destroyed hundreds of homes, but the real cost came in the form of muddier water, reduced pollination, and dirty air. Then something peculiar happened: the fire slowed when it hit the more naturally-managed Yosemite forest, offering one more key to help us manage forests in a changing climate….

     

     

     

     

    Stinky gases emanating from landfills could transform into clean energy

    Posted: 12 Aug 2014 09:16 AM PDT

    A new technique transforming stinky, air-polluting landfill gas could produce the sweet smell of success as it leads to development of a fuel cell generating clean electricity for homes, offices and hospitals, researchers say. The advance would convert methane gas into hydrogen, an efficient, clean form of energy.

     

     

    Wind Comes To The Rescue When Four Aging Nuclear Plants Shut Down In The U.K.

    August 12, 2014

    A standard criticism of wind and solar power is that they are intermittent energy sources and depend on blowing wind or shining sun in order to produce energy. Because of this, traditional power plants like coal, gas, and nuclear are still required as baseload sources that can be relied on to generate 24 hours a day. This relationship is changing as renewable energy storage improves, baseload renewable sources like geothermal and hydropower are further incorporated, and smart grid technology enhances deployment. In the U.K. this week the tables have temporarily turned as wind power is replacing an unanticipated lack of nuclear generation from the nation’s grid. On Monday, EDF Energy announced it was shutting down four of its U.K. reactors, or around a quarter of its total nuclear generating capacity, after a defect had been found on the boiler spine of a reactor. The company decided to take the “conservative decision” to shut down three other reactors, though no radioactive release or injuries were reported. The reactors are expected to remain closed for about two months. EDF, a French state-owned utility, said the current closures should not effect the U.K.’s energy supply thanks to the low-demand summer season and “a lot of wind power that is being generated right now.”…

     

    Wind Farm Powering A Million Homes Nears Approval Deep In Coal Country

    August 11, 2014

    Pronghorn antelope graze on the prairie at Duke Energy’s Campbell Hill Windpower Project near Casper, Wyoming.

    A massive wind farm in Wyoming is getting closer to reality. Last week Wyoming’s Industrial Siting Council voted unanimously to approve a permit to construct and operate the Chokecherry and Sierra Madre Wind Energy Project, which could eventually generate 3,000 megawatts of energy — enough to power nearly one million households. The $5 billion project, which could include up to 1,000 wind turbines, is being undertaken by Power Company of Wyoming. The Power Company is a wholly-owned affiliate of Denver billionaire Phil Anschutz’s The Anschutz Corp, which also has holdings in oil and gas infrastructure and electricity transmission. The permit is the last major non-federal permit needed to move the project forward, however the U.S. Bureau of Land Management is still working on two environmental assessments to be released in the near future. This includes the issuance of rights-of-way grants. The company has also applied for an eagle take permit from the U.S. Fish and Wildlife Service which would allow the project to kill a certain number of raptors in exchange for implementing conservation measures…

     

    Keystone XL’s Climate Impact Could Be Four Times Greater Than State Department Claimed

    by Emily Atkin Posted on August 11, 2014

    If the controversial northern leg of the Keystone XL pipeline is approved and built, the resulting amount of carbon emitted into earth’s atmosphere could be up to four times greater than the U.S. State Department estimated, a new scientific paper shows. Researchers Peter Erickson and Michael Lazarus of the Stockholm Environmental Institute say the State Department’s assessment of the pipeline’s potential carbon emissions failed to consider whether consumer demand for Canadian tar sands oil — the type that would be transported in Keystone XL — would increase worldwide if the pipeline is built. If it is built, it could cause a rush of new Canadian tar sands crude oil to come on to the global market. If that happens, global prices of oil will decrease, and demand for it will increase. If demand increases, more oil will be burned, causing increased carbon emissions. Depending on how much the pipeline increases oil production, its climate impact could amount to anywhere from zero to 110 million tons of carbon dioxide emissions per year, the study showed. That’s a margin that’s four times wider than what the State Department forecasted — an emissions range of 1 million and 27 million tons of carbon dioxide per year….

     

     

    Methane leaks add to greenhouse effect.
    Sacramento Bee, California

    The natural gas pipelines snaking under the Sacramento region likely leak a significant amount of methane, a potent greenhouse gas, scientists say. The amount of methane that leaks out is relatively small, but scientists say it has a big impact, since methane traps about 25 times more heat than CO2.

     

     


    Group Earns Oil Income Despite Pledge on Drilling

    The nation’s largest environmental group is earning money from an oil well on land it controls in Texas, despite pledging a decade ago not to permit new oil and gas drilling on land supposedly set aside for conservation. That revelation is contained in a forthcoming book about climate change by the writer and activist Naomi Klein, and the essential facts of the case were confirmed last week by the Nature Conservancy, the environmental group in question. The Nature Conservancy — which says it helps protect about 20 million acres in the United States — argues that it has had no choice in the case of the well. Under the terms of a lease it signed years ago with an oil and gas company and later came to regret, the group says it had to permit the drilling of the well in 2007….

    The Perils of Aging: A Problem for Citizen Science?

    Errors creep into bird population surveys as volunteers get older, new study says.

    Katie Langin National Geographic Published August 6, 2014

    Each spring, thousands of binocular-clad volunteers scour natural areas across North America to count birds in the name of science. This gargantuan effort helps scientists take the pulse of bird populations and make important management decisions—but errors creep into the data as volunteers age, according to a new study. Bird-watchers over 50 weren’t as proficient as younger volunteers—those under 40—at detecting 13 (of 43 examined) songbird species during surveys for the Atlas of the Breeding Birds of Ontario in Canada. (Check out National Geographic’s photo gallery of songbirds.)

    In some respects, this doesn’t come as a huge surprise: The aging process tends to knock out our ability to hear high-pitched sounds, and most songbirds are detected by hearing their song rather than seeing them flit through the trees. But—contrary to expectations—the songs produced by the 13 problematic species did not cluster at the higher-pitched end of the spectrum. Some of the species, like the yellow-bellied flycatcher, sing relatively low-pitched songs. “I was surprised that the results were not as strong for hearing loss as we might have expected,” said Robert Farmer, the lead author of the study, published in the June issue of the journal

    False Balance Lives: Media Biased Toward Fringe Climate Scientists Who Reject Global Consensus



    by Joe Romm Posted on August 11, 2014

    CREDIT: Shutterstock

    A new study finds that the media disproportionately favors scientists who reject the basic scientific consensus on climate change. By consensus, I mean the latest findings of the Intergovernmental Panel On Climate Change (IPCC), which are already overly cautious and watered down. Some — though not most — analysts have declared the media’s era of false balance in climate coverage is over. But the truth is that the media continue to present the public a misleading picture on climate science, giving fringe scientists more attention (disproportionate to their actual number) than the leading climate scientists. Reporters need to learn that, if they wish to discuss “both sides” of the climate issue, the scientifically legitimate “other side” is that, if anything, global climate disruption is likely to be significantly worse than has been suggested in scientific consensus estimates to date….

    Size matters when convincing your brain to eat healthier foods

    Posted: 11 Aug 2014 03:02 PM PDT

    Playing with the portions of good and not-so-good-for-you foods is better than trying to eliminate bad foods, according to a study. The idea is to not give up entirely foods that provide pleasure but aren’t nutritious. Instead, the focus should be on lowering the portion of the “vice” foods and correspondingly raising the portion of a healthy food to replace it, researchers report.
