NOAA has issued a report on a small part of the recent brutal droughts that have hit the United States over the past few years. The report “An Interpretation of the Origins of the 2012 Central Great Plains Drought” is needlessly confusing, problematic scientifically, and already leading to misleading headlines.
Dr. Kevin Trenberth, head of the Climate Analysis Section at the National Center for Atmospheric Research, has sent to reporters a Commentary on the report, which I repost below. He concludes:
This report has some useful material in it describing aspects of the drought in 2012 in the central US. But it is quite incomplete in many respects, and it asks the wrong questions. Then it does not provide very useful answers to the questions that are asked.
Indeed, it seems odd to do a 44-page report on the drought in the Central Great Plains (in the spring and summer of 2012) when so much of the Great Plains — and Southwest — has also been in a brutal extended drought that continues to this day.
Measuring microbes makes wetland health monitoring more affordable, says researcher
(April 9, 2013) — Wetlands serve as Earth’s kidneys. They filter and clean people’s water supplies while serving as important habitat for many species, including iconic species like cattails, cranes and alligators. Conventional ecosystem health assessments have focused on populations of these larger species. However, the tiny, unseen creatures in the wetlands provided crucial indicators of the ecosystems’ health in a study by University of Missouri Associate Professor of Engineering Zhiqiang Hu and his team…..Tiny, unseen wetland creatures provided crucial indicators of the ecosystems’ health in a new study. Using analysis of the microbiological health of wetlands is cheaper and faster than traditional assessments, and could lead to improvements in harnessing natural processes to filter human’s wastewater. … “Microbes form the base of the wetland food chain and nutrient cycle, so the health of their populations reverberates through the ecosystem,” said Hu. “However, analyzing their populations was once too difficult. Now, advances in microbial analysis allow us to more easily and accurately identify the species present in soil or water samples. This could become a vital tool to complement other forms of wetland health evaluation.” Hu’s team, led by former MU doctoral student Atreyee Sims, found that a higher ratio of certain microbes, known as archaea, to bacteria was a good sign of a healthy ecosystem. When a few species of bacteria dominated the samples, the wetland was probably contaminated and unhealthy from the ground up, Sims concluded…. > full story
Environmental change triggers rapid evolution
(April 9, 2013) — Environmental change can drive hard-wired evolutionary changes in animal species in a matter of generations. A new study overturns the common assumption that evolution only occurs gradually over hundreds or thousands of years. Instead, researchers found significant genetically transmitted changes in laboratory populations of soil mites in just 15 generations, leading to a doubling of the age at which the mites reached adulthood and large changes in population size. The results have important implications in areas such as disease and pest control, conservation and fisheries management because they demonstrate that evolution can be a game-changer even in the short-term…Although previous research has implied a link between short-term changes in animal species’ physical characteristics and evolution, the Leeds-led study is the first to prove a causal relationship between rapid genetic evolution and animal population dynamics in a controlled experimental setting….Professor Benton said: “The traditional idea would be that if you put animals in a new environment they stay basically the same but the way they grow changes because of variables like the amount of food. However, our study proves that the evolutionary effect — the change in the underlying biology in response to the environment — can happen at the same time as the ecological response. Ecology and evolution are intertwined,” he said. … > full story

The fisher (Martes pennanti) is a cat-sized carnivore found in coniferous and mixed conifer and hardwood forests across Canada and in four regions of the United States, including New England, the Great Lakes, the northern Rockies, and the Pacific Northwest. Now a candidate species for listing under the Endangered Species Act, fishers in California are falling victim to rodenticides used on illegal marijuana crops scattered throughout the state’s public and tribal lands.

Silent Forests? Rodenticides on Illegal Marijuana Crops Harm Wildlife
2013 Spring — March 17, 2013 Wildlife Society News By Mourad W. Gabriel, Greta M. Wengert, J. Mark Higley, Shane Krogan, Warren Sargent, and Deana L. Clifford
Another mortality signal on the radio collar of a fisher (Martes pennanti) pulses on a wet spring morning, and fear of a repeat of the previous spring’s mortalities looms in the backs of our minds. Hoopa tribal biologists scramble to recover the fisher quickly so that a necropsy can be performed to determine cause of death. The field crew reports back that the fisher is not dead but lethargic and lurching on the ground when it attempts to seek cover from approaching biologists. A conference call among researchers, a wildlife pathologist, and a veterinary toxicologist follows to determine the next course of action. Unfortunately, the consensus is humane euthanization. Though testing is ongoing, this is likely the sixth monitored fisher in California that has died from second-generation anticoagulant rodenticide (SGAR) toxicosis since 2009. Linking SGARs to multiple deaths of a rare forest carnivore has been an alarming discovery. Even more unsettling: We’ve learned that these deaths appear to be linked to illegal marijuana cultivation on community and public lands — a finding that raises serious concerns for the health of many species of wildlife including fishers, an Endangered Species Act candidate…..

Smart solutions to a worsening water crisis
(April 10, 2013) — Innovative policies and new technologies that reduce water waste are helping countries across the Middle East and North Africa deal with chronic water shortages. … Those advances spring from the simple idea that preventing water loss is effectively the same as giving parched countries new sources of water. This view gained widespread credibility in the wake of an IDRC-supported research program designed to assess how the so-called “water demand management” approach could ease the region’s water crisis…. arlier, governments had seen big, costly projects such as dams, canals, and salt-water desalination plants as the solution to water scarcity. By the mid-1990s, the megaproject approach was widely viewed as a poor response to a water crisis worsened by population growth and climate change. However, the “demand management” alternative to developing new supplies of water — for example, reducing the amount of water used, wasted, or even needed — remained unproven….> full story

The story of the decade is the collapse of Arctic sea ice and its impact on our extreme weather (see “CryoSat-2 Confirms Sea Ice Volume Has Collapsed“).
Many experts now say that if recent volume trends continue we will see a “near ice-free Arctic in summer” within a decade. And that may well usher in a permanent change toward extreme, prolonged weather events “such as drought, flooding, cold spells and heat waves.”
It will also accelerate global warming in the region, which in turn will likely accelerate both the disintegration of the Greenland ice sheet as well as the release of the vast amounts of carbon currently locked in the permafrost, which in turn will likely add 0.4°F – 1.5°F to total global warming by 2100.
For more on the death spiral, here’s Peter Sinclair’s latest video, featuring an interview with Walt Meier of the National Snow and Ice Data Center:

Both images: Lonnie G. Thompson/Ohio State University The Qori Kalis glacier in Peru, a tongue of ice extending down a valley from the mighty Quelccaya ice cap, has been melting rapidly. Pull the slider with your mouse to compare a picture taken in 1978, left, with one taken in 2011.
Glacial ice in the Peruvian Andes that took at least 1,600 years to form has melted in just 25 years, scientists reported Thursday, the latest indication that the recent spike in global temperatures has thrown the natural world out of balance. .. The evidence comes from a remarkable find at the margins of the Quelccaya ice cap in Peru, the world’s largest tropical ice sheet. Rapid melting there in the modern era is uncovering plants that were locked in a deep freeze when the glacier advanced many thousands of years ago. Dating of those plants, using a radioactive form of carbon in the plant tissues that decays at a known rate, has given scientists an unusually precise method of determining the history of the ice sheet’s margins. Lonnie G. Thompson, the Ohio State University glaciologist whose team has worked intermittently on the Quelccaya ice cap for decades, reported the findings in a paper released online Thursday by the journal Science. The paper includes a long-awaited analysis of chemical tracers in ice cylinders the team recovered by drilling deep into Quelccaya, a record that will aid scientists worldwide in reconstructing past climatic variations.
Such analyses will take time, but Dr. Thompson said preliminary evidence shows, for example, that the earth probably went through a period of anomalous weather at around the time of the French Revolution, which began in 1789. The weather presumably contributed to the food shortages that exacerbated that upheaval. “When there’s a disruption of food, this is bad news for any government,” Dr. Thompson said in an interview. Of greater immediate interest, Dr. Thompson and his team have expanded on previous research involving long-dead plants emerging from the melting ice at the edge of Quelccaya, a huge, flat ice cap sitting on a volcanic plain 18,000 feet above sea level. …
Throughout the Andes, glaciers are now melting so rapidly that scientists have grown deeply concerned about water supplies for the people living there. Glacial meltwater is essential for helping Andean communities get through the dry season. In the short run, the melting is producing an increase of water supplies and feeding population growth in major cities of the Andes, the experts said. But as the glaciers continue shrinking, trouble almost certainly looms. Douglas R. Hardy, a University of Massachusetts researcher who works in the region, said, “How much time do we have before 50 percent of Lima’s or La Paz’s water resources are gone?”

Climate change will bring more and more extreme precipitation events this century. A new study from NOAA’s National Climatic Data Center confirms what climate scientists have long been saying about climate change’s effect on the hydrological cycle. If you are not familiar with this term, you are certainly familiar with what it describes. As the sun warms the earth, water evaporates from oceans, lakes, and rivers, which then form clouds that produce rain and snow. More evaporation happens when the ocean
the air is warmer, which has been happening steadily for some time. The NOAA study, published in Geophysical Research Letters, found that extreme precipitation events will become more intense this century as the globe continues to warm. Extra moisture expected from that warming will be the dominant factor fueling this increase in extreme precipitation, with a 20 to 30 percent more precipitation in the Northern Hemisphere by 2099.
The paper looked at three factors that go into the maximum precipitation value possible in any given location: moisture in the atmosphere, upward motion of air in the atmosphere, and horizontal winds. The team examined climate model data to understand how a continued course of high greenhouse gas emissions would influence the potential maximum precipitation. While greenhouse gas increases did not substantially change the maximum upward motion of the atmosphere or horizontal winds, the models did show a 20-30 percent increase in maximum moisture in the atmosphere, which led to a corresponding increase in the maximum precipitation value.

They looked at possible changes in winds that could offset increased water vapor, but found that those changes would be too small. We already know that specific events cannot be said to be directly caused by climate change, but as Kevin Trenberth puts it, “All weather events are affected by climate change because the environment in which they occur is warmer and moister than it used to be.” And we know that NOAA’s projections have already started to become the reality: a study in Nature
found that several of the last decade’s extreme weather events would not have occurred without climate change. The study’s authors hope that this will allow water managers, engineers, and infrastructure planners to better identify risks and mitigate potential disasters. National reports like this are valuable not only because funds for flood risk prevention studies are often attacked in Congress, but because climate impacts are often ignored, forcibly, at the state level. South Carolina buried an important report on climate impacts. North Carolina made it illegal to consider the latest climate science when preparing coastal regions for sea level rise.

Since the late 1990s, climate change has driven a massive expansion of forest-destroying Mountain Pine Beetles in Canada, delivering the country one of the worst ecological disasters in its history. The insects are not technically invasive, and until recently they existed in a natural balance with their environment; killing off older trees and making room for new growth. But as a new documentary chronicles, climate change eliminated many of the natural limits on the beetles’ geographic spread and their rate of reproduction.

LONDON—Tourists, exchange students, masters of the financial universe and other business travelers: It’s time to buckle up. More pollution is likely to mean bumpier flights for trans-Atlantic travelers, researchers say, predicting increased turbulence over the North Atlantic as carbon dioxide levels rise. University of East Anglia climate expert Manoj Joshi said scientists have long studied the impact of the carbon-heavy aviation industry on climate change but he took a new tack. “We looked at the effect of climate change on aviation,” he said. In a paper published Monday in the journal Nature Climate Change, Joshi and colleague Paul Williams ran a climate simulation that cranked up the level of carbon dioxide in the atmosphere to twice its pre-industrial level—roughly 50 percent more than now. Williams said they ran a series of turbulence-predicting algorithms for the North Atlantic winter period and compared the results to pre-industrial rates.
Queasy fliers need read no further.
Williams said the results showed a 10-to-40 percent increase in the median strength of turbulence and a 40-to-170 percent increase in the frequency of moderate-or-greater turbulence. He described the latter as shaking that is “strong enough to force the pilot to switch on the seat-belt sign, knock over drinks, and make it difficult to walk.”
The explanation is that some models predict that global warming will draw the jet stream further north,
creating more of the vertical wind shear that causes turbulence.
Joshi said choppier skies might prompt pilots to reroute their flights. But the North Atlantic is a busy place for air travel, with an average of 960 flights a day last week, according to aviation data companies masFlight and OAG. Pilots interviewed by The Associated Press said—in such a crowded air corridor—planes were just as likely to simply power through.
“You just got to grin and bear it,” said Steven Draper, a retired airline pilot and a spokesman for the British Airline Pilots Association. Although there’s no clear evidence of rougher skies just yet, Draper did say he’d seen worse weather—like storms—near the end of his career.
“My experience was that they were increasing in intensity and frequency,” he said. ….
Top regions may be too hot by 2050 – but coast, mountains could thrive
By David Perlman SF Chronicle April 11, 2013
Winegrowers in California and around the world will be forced to move their vineyards to cooler environments within the next few decades as climate change causes temperatures to rise, conservation biologists say in a study to be published this week. Think Yellowstone Pinot Noir or Chateau Yukon Cabernet.
Not that those are likely new venues for high-end premium grapes, but a new analysis warns that the world’s warming climate will put new strains on water supplies for vineyard irrigation. And without adequate planning, the scientists warned, any movement to the north by grape growers into critical habitat will pose new threats to wildlife.
The analysis by a team of international researchers, to be published online in the Proceedings of the National Academy of Sciences, indicates that California’s coastal vineyards are least likely to be at risk because of their proximity to the Pacific Ocean, which moderates California’s coastal climate.
But in the Central Valley, as well as in the world’s warmer grape-growing regions, water supplies will be heavily stressed as growers are forced to compete for irrigation water with other crop growers, said Lee Hannah, a biologist and climate specialist with Conservation International who led the study.
At the current rate of climate change, by 2050 vineyard owners could be pushing into California regions that are now considered unsuitable for wine growing, like the higher slopes of the Sierra and the northern redwood forests, Hannah said.
Only careful planning will ward off conflicts between winegrowers and wildlife defenders, said Rebecca Shaw, a climate policy analyst with the Environmental Defense Fund.
The “Yellowstone-Yukon corridor” is a typical region that is currently “unsuitable” for wine growing, but where vineyards could become widespread in the next 40 years, according to the scientists’ analysis.
Wine is made in the Yellowstone area now, and some farmers grow grapes there, but Montana’s eight licensed wineries specialize in making wines mostly from cherries, rhubarb, blueberries, pears and other fruits, according to the Montana Commerce Department.
Matthiasson in the barrel room at Silenus Vintners, where he produces his wine.
In Australia, Hannah said, many grape growers are already expanding their vineyards southward into Tasmania, where cooler climates previously have inhibited full ripening, but where global warming is making the region a better fit for wine.
And in South Africa, winegrowers are planning moves to higher altitudes for their expanded vineyards, Hannah said.
In Napa, noted wine consultant Steve Matthiasson, who produces wine from his family vineyard, called the new analysis “a great report.”
“I agree with it. It’s right on,” he said. “It’s time we think hard about it so we growers can move out of the abstract. Remember, grapes are very adaptable. Even now they’re growing grapes in the Coachella Valley, where it’s really hot.” One way growers can adapt to global warming, Matthiasson said, is to start planning now to use less water for irrigation by planting drought-tolerant rootstocks and by irrigating longer but less frequently so “root zones” go deeper. Vineyard rows can also be shifted to allow leaves to give more protection to ripening grapes, he said.

Think the Planet Isn’t Warming? Check the Ocean
Apr 11, 2013 05:11 AM ET // by Kieran Mulvaney
A recent article in The Economist stated that “over the past 15 years air temperatures at the Earth’s surface have been flat while greenhouse-gas emissions have continued to soar.” The Economist went to great lengths to point out that “the mismatch between rising greenhouse-gas emissions and not-rising temperatures … does not mean global warming is a delusion.” But the piece was predictably lauded by climate skeptics as “further evidence” of the case against climate change.
Except that … it wasn’t. As The Economist piece itself pointed out, this wasn’t an argument that “global warming has ‘stopped.‘” The past two decades have been the hottest in recorded history; of the nine hottest years on record, eight have come since 2000. The question, though, is why the year-on-year/decade-on-decade increase appears to have been somewhat less in the past 10 to 15 years, given the ongoing increase in atmospheric greenhouse gas concentrations.
To which there are several answers.
First, the smaller the temporal time scale, the more the short-term fluctuations, forcings and feedbacks — from aerosol emissions to La Niña events — can distort the bigger picture. Over a longer scale, the evidence is increasing that the rate of warming is probably unprecedented in over 11,000 years.
Second, The Economist article, and the skeptic narrative that has absorbed it, focuses on what is known as “climate sensitivity,” which is how much surface warming the planet will experience in response to a doubling of atmospheric carbon dioxide concentrations relative to pre-Industrial Revolution levels. (Those pre-industrial levels were approximately 280 ppm; a doubling therefore would be roughly 560 ppm. Present levels are closing in on 397 ppm.)
But, as climate blogger Joe Romm points out, climate sensitivity is but one factor in determining how much the planet will warm in the future; another hugely important one is the extent to which CO2 concentrations will actually increase, and present trends suggest they will blow past 560 ppm and wind up closer to 1,000 ppm. Additionally, while climate sensitivity estimates are greatly influenced by short-term feedbacks such as sea ice extent and water vapor, they do not factor in “slow” feedbacks, such as the release of methane as a result of tundra melt. Nor do they consider the non-linearity of such feedbacks – i.e. the fact that they may become significant relatively suddenly.
Third, the data referred to by The Economist suggest that climate sensitivity may be at the very low end of projected estimates of between 2 degrees Celsius and 4.5 degrees Celsius. If that indeed does prove to be the case, then that’s obviously good news. But, as Zeke Hausfather pointed out in a post at the Yale Forum on Climate Change and the Media: “A world with a relatively low climate sensitivity — say in the range of 2 °C — but with high emissions and with atmospheric concentrations three to four times those of pre-industrial levels is still probably a far different planet than the one we humans have become accustomed to. And it’s likely not one we would find nearly so hospitable.”
Finally, and most importantly, there is plenty of reason to suspect that climate sensitivity isn’t lower than expected; because, critically, discussions of climate sensitivity tend to focus on surface warming of the planet; but several recent studies have shown that in fact an increasing amount of warming is taking place beneath the surface, in the ocean depths.
Ninety percent of warming goes into heating, not the land or the atmosphere, but the ocean; two recent papers, in 2012 and earlier this year, showed that approximately 30 percent of recent ocean warming has been taken up by waters below depths of 700 meters (about 2,300 feet), where few measurements had previously taken place. That was reinforced by a European study, published earlier this week, which, according to Reuters, found “that the oceans took up more warmth from the air around 2000. That would help explain the slowdown in surface warming but would also suggest that the pause may be only temporary and brief … Lead author Virginie Guemas of the Catalan Institute of Climate Sciences in Barcelona said the hidden heat may return to the atmosphere in the next decade, stoking warming again.”
April 9, 2013 SAN FRANCISCO -– A federal judge struck a major blow against fracking in California this week, ruling that the government was wrong to allow energy companies to drill for oil on 2,700 acres of public land without first considering environmental impacts. The Bureau of Land Management’s assessment of the land “did not adequately consider the development impact of hydraulic fracturing techniques,” wrote U.S. Magistrate Judge Paul Grewal in a decision made public on Monday that sided with environmental groups that sued the BLM.
The land in question sits atop the Monterey Shale, a formation of sedimentary rock stretching beneath much of Central California, which the U.S. Energy Information Administration estimates contains more than 15 billion barrels of oil. But the oil can only be reached through hydraulic fracturing, or fracking, an invasive process that injects vast amounts of water, sand and chemicals to create cracks in the rock and force the oil to the surface.Before auctioning off mineral rights to the land in 2011, BLM was required to analyze potential environmental consequences. The agency’s 125-page report, however, characterized fracking as “not relevant to the analysis of impacts … because the reasonable foreseeable development scenario anticipates very little (if any) disturbance to the human environment.” Based on this, BLM declared that drilling into federal lands would create “no significant environmental impact” and signed off on the leases.
A coalition of environmental groups, including the Center for Biological Diversity and the Sierra Club, sued BLM over the auction, arguing that fracking threatened significant detrimental effects on water quality and on endangered species. Judge Grewal sided with the plaintiffs, charging that the government didn’t take fracking sufficiently into account. “Rather than engaging in this reality by at least considering what impact might result from fracking on the leased lands, whatever its ultimate conclusion, BLM chose simply to ignore it, asserting that ‘these issues are outside the scope of this … [environmental analysis] because they are not under the authority or within the jurisdiction of the BLM,” the judge wrote. “If not within BLM’s jurisdiction, then whose?”….
California Senate Panel Approves Bill to Regulate Fracking
The Sacramento Bee, 4/10/13
A bill to more tightly regulate the drilling process called hydraulic fracturing cleared a Senate committee Tuesday. Fracking, as the extraction technique is commonly called, has become a flash point for environmental advocates as the process has become more commonplace in recent years. California is in the incipient stages of regulating fracking, which involves shooting a mix of chemicals, sand and water deep underground.
….Two years ago I wrote an article entitled ‘Americans Characteristically Uninformed About Climate Change‘ in the wake of that years’ Environmental poll. When asked “How much do you personally worry about global warming?” those who worried “a great deal” and “fair amount” had reached an almost all-time low of 51% of respondents. The lowest had been a response of only 50% in 1998, compared with 72% two years later.This year, respondents in the 2013 Environmental poll were asked the same question, and the continuing growth in concern has continued. 2012 showed 55% were worrying “a great deal” and “a fair amount” while this year that number has jumped up to 58%. They aren’t great numbers, but they are growing numbers.
More specifically, 33% of Americans worry about global warming “a great deal,” 25% worry “a fair amount,” 20% “only a little,” and 23% “not at all.” That last number is somewhat terrifying, and somewhat representative of a continuing segment of the American population’s attitudes towards global warming, and the environment as a whole…..

Crop losses. Floods. Wildfires. Climate change and extreme weather are fundamentally changing the United States, and American taxpayers are paying a huge, and growing, cost. The U.S. Government Accountability Office warned in February that climate change is a “significant financial risk to the federal government.” It threatens everything — not just federal lands and buildings, but food, flood and crop insurance, and disaster relief. And who pays for all of this? We do, the American taxpayers — a threat to the government’s wallet is a threat to our own bottom line. Here are several examples of the escalating costs Americans are already bearing.
Food Taxpayers subsidize the federal crop insurance program that was created during the 1930s Dust Bowl to protect farmers against crop losses. Today, we’re experiencing another devastating drought, and federal crop insurance losses have tripled in the past three years to $16 billion in payouts for 2012. That’s a cost of $51 a year for every man, woman and child in America.
And these costs are likely to continue — the latest numbers from the U.S. Drought Monitor show nearly 67 percent of the contiguous U.S. is now experiencing some level of drought.
Floods The National Flood Insurance Program (NFIP) is staggering under massive losses after Superstorm Sandy, which triggered more than 115,000 new claims in just the first two weeks after the storm.
Although NFIP collects about $3.5 billion a year in premiums, the amount of claims the agency has paid out has exceeded the amount collected in four of the past eight years, leading to increased borrowing by the federal government (in other words, taxpayers) to fill the gap. Last year’s losses in Sandy’s wake are expected to approach $8 billion. That’s $25 for every American. [How Sandy Compares to the Worst US Natural Disasters] Keep in mind, that figure doesn’t even include the $50 billion of disaster relief that Congress approved in January for Sandy-impacted states. And with sea levels rising and storm surges reaching further inland because of climate change, risks to coastal communities and costs to taxpayers will continue to rise….
Senate OKs Sally Jewell as New Interior Secretary
Los Angeles Times, 4/10/13 The Senate approved REI Chief Executive Sally Jewell Wednesday as the new secretary of the Interior by a vote of 87 to 11. Jewell, 58, had faced tough questioning by some Senate Republicans during her confirmation hearing in early March. But in comparison to some Obama Cabinet nominees, she sailed through the committee and full Senate votes.
NWRA Welcomes Sally Jewell as the Next Secretary the Interior
Washington, D.C.–The National Wildlife Refuge Association today expressed its strong support for Sally Jewell as the next Secretary of the U.S. Department of the Interior following the Senate’s confirmation of her nomination last night. Jewell’s appreciation for the outdoors and wildlife as well as her extensive knowledge of the economic benefits of our natural resources will bring a unique perspective in the President’s cabinet.
“We are extremely pleased by the Senate’s confirmation of Sally Jewell to be the 51st Secretary of the Interior and look forward to working closely with her to grow our nation’s commitment to wildlife conservation at a landscape level, in places such as the Everglades Headwaters National Wildlife Refuge and Conservation Area in Florida, the Silvio Conte National Fish and Wildlife Refuge in the Connecticut River watershed and Cache River National Wildlife Refuge in Arkansas.” said David Houghton, President of the National Wildlife Refuge Association. “She will undoubtedly be an excellent spokesperson for the President’s America’s Great Outdoors initiative and will continue to bring attention to our nation’s great public lands.”
Jewell has earned national recognition for her management skills of the nearly $2 billion outdoor equipment company, REI. This expertise makes her uniquely qualified to lead an agency with hundreds of millions of acres of lands where Americans go to enjoy outdoor recreation.
The U.S. Fish and Wildlife Service’s National Wildlife Refuge System is a haven for outdoor enthusiasts. The sun literally never sets on its 150 million acres spanning 560 units from Guam to Puerto Rico. Over 40 million annual visitors contribute over $4.2 billion in economic output and over 34,000 jobs from recreation-related spending. National wildlife refuges and their recreational opportunities is part of a growing industry in the United States. Jewell’s leadership at the helm of the Department of Interior comes at a crucial time.
“Sally Jewell has been a leader in the outdoor recreation industry using innovative strategies to protect and restore wildlife habitat throughout the Pacific Northwest and across the country; as Secretary of the Interior, she will have an opportunity to articulate and implement a larger conservation vision for the nation.” said Houghton. “We look forward to working with her to further the goals and mission of the U.S. Fish and Wildlife Service and National Wildlife Refuge System.”

California utilities to get a third of their power from renewable sources, the country’s most aggressive clean energy standard (AP Photo)
By Jorge Madrid via EDF
California has a thriving clean economy. In fact, the Golden State boasted more green jobs in clean energy and transportation last year than the other top 4 states combined, according to a new report by Environmental Entrepreneurs. Here are some more highlights:
Innovation: The state is a hub for clean energy innovation. Clean technology patents grew by 26 percent in the past 2 years, outpacing the country and the rest of the world. It is the “undisputed leader in solar technology patents” according to Next10.org, with totals greater than the cumulative solar patents of the next eight highest states.
Energy Generation: Total renewable energy generation has grown 28 percent between 2007 and 2011 and wind energy has doubled during this same period. Earlier this month, the state broke its own record for solar power — over 15,394 megawatt-hours of power to the grid, enough for every Californian to keep a 100-watt bulb lit for four hours. Not to be outdone, the state also surpassed 4-gigawatts of wind power — similar to what California’s two nuclear plants can churn out at full power, or enough to momentarily supply over 2.5 million homes……

Modeling potential range shifts under a changing climate: A case study
Wednesday, April 17, 1:00-2:30 PM Eastern
- Scott D. Klopfer, Director, Conservation Management Institute, Virginia Tech
- David Kramar, Conservation Management Institute, Virginia Tech
- Chris Burkett, Wildlife Action Plan Coordinator, VA Dept. of Game & Inland Fisheries
- Austin Kane, Science and Policy Manager, National Wildlife Federation
Description: Climate change, and its potential impact on species distributions, has moved to the forefront of concerns among wildlife managers. Current speculation in Virginia centers on how species will respond to changing climate in the coming century. We used dynamically downscaled climate models to generate change scenarios in the mid and late 21st century. We used that information, along with available species occurrence information, to build predictive spatial models for a select group of species. Our results suggested that the impact of climate change will vary across the landscape. The resulting species distribution models provide information for wildlife managers on how climate changes may result in shifting distributions in Virginia. We also provide some basic suggestions to managers in using the information produced and in incorporating climate change into their decision making.

Apr. 10, 2013 — Scientists today answered a question that worries millions of owners and potential owners of electric and hybrid vehicles using lithium-ion batteries: How long before the battery pack dies, leaving a sticker-shock bill for a fresh pack or a car ready for the junk heap? Their answer, presented here at the 245th National Meeting & Exposition of the American Chemical Society (ACS), being held in New Orleans this week, may surprise skeptics. “The battery pack could be used during a quite reasonable period of time ranging from 5 to 20 years depending on many factors,” said Mikael G. Cugnet, Ph.D., who spoke on the topic. “That’s good news when you consider that some estimates put the average life expectancy of a new car at about eight years.”
Cugnet explained that the lifespan depends mainly on the battery’s temperature, state of charge and charge protocol. Battery performance begins to suffer as soon as the temperature climbs above 86 degrees Fahrenheit. “The higher the temperature, the lower the battery service life,” he said. “A temperature above 86 degrees F affects the battery pack performance instantly and even permanently if it lasts many months like in Middle East countries.” Cugnet also recommended that electric vehicle (EV) owners pay attention to how much their battery is charged, another factor in a battery’s longevity. He reported that a fully-charged battery is more vulnerable to losing power at temperatures above 86 degrees F.
