BY many measurements, this summer’s drought is one for the record books. But so was last year’s drought in the South Central states. And it has been only a decade since an extreme five-year drought hit the American West. Widespread annual droughts, once a rare calamity, have become more frequent and are set to become the “new normal.”
Until recently, many scientists spoke of climate change mainly as a “threat,” sometime in the future. But it is increasingly clear that we already live in the era of human-induced climate change, with a growing frequency of weather and climate extremes like heat waves, droughts, floods and fires.
Future precipitation trends, based on climate model projections for the coming fifth assessment from the Intergovernmental Panel on Climate Change, indicate that droughts of this length and severity will be commonplace through the end of the century unless human-induced carbon emissions are significantly reduced. Indeed, assuming business as usual, each of the next 80 years in the American West is expected to see less rainfall than the average of the five years of the drought that hit the region from 2000 to 2004.
That extreme drought (which we have analyzed in a new study in the journal Nature-Geoscience) had profound consequences for carbon sequestration, agricultural productivity and water resources: plants, for example, took in only half the carbon dioxide they do normally, thanks to a drought-induced drop in photosynthesis.
In the drought’s worst year, Western crop yields were down by 13 percent, with many local cases of complete crop failure. Major river basins showed 5 percent to 50 percent reductions in flow. These reductions persisted up to three years after the drought ended, because the lakes and reservoirs that feed them needed several years of average rainfall to return to predrought levels.
In terms of severity and geographic extent, the 2000-4 drought in the West exceeded such legendary events as the Dust Bowl of the 1930s. While that drought saw intervening years of normal rainfall, the years of the turn-of-the-century drought were consecutive. More seriously still, long-term climate records from tree-ring chronologies show that this drought was the most severe event of its kind in the western United States in the past 800 years. Though there have been many extreme droughts over the last 1,200 years, only three other events have been of similar magnitude, all during periods of “megadroughts.”
Most frightening is that this extreme event could become the new normal: climate models point to a warmer planet, largely because of greenhouse gas emissions. Planetary warming, in turn, is expected to create drier conditions across western North America, because of the way global-wind and atmospheric-pressure patterns shift in response.
Indeed, scientists see signs of the relationship between warming and drought in western North America by analyzing trends over the last 100 years; evidence suggests that the more frequent drought and low precipitation events observed for the West during the 20th century are associated with increasing temperatures across the Northern Hemisphere……

Birds: Time to accept conservation triage (NATURE – subs. required-contact firstname.lastname@example.org) John A. Wiens, Dale D. Goble & J. Michael Scott Nature 488, 281 (16 August 2012) doi:10.1038/488281c Published online 15 August 2012
Like the troubled California condors Gymnogyps californianus (Nature 486, 451; 2012), more than 80% of endangered US species are imperilled by threats that cannot be eliminated, only managed. These species are “conservation reliant” (J.M. Scott et al. Conserv. Lett. 3, 91–97; 2010). For example, the endangered Kirtland’s warbler (Setophaga kirtlandii) has exceeded…
These green cowboys try to marry good stewardship of the land with making money.
By Todd Wilkinson, Correspondent / July 29, 2012 ….”Being a smart rancher – one who’s still going to be here in another 50 years – isn’t based on how you dress,” says Jones. “It comes down to how you treat the land and build resilience over time that matters. In particular, it’s about how well you manage grass and water.” Normally, listening to a cattleman talk with reverence about managing grass and water, using terms like “holistic” and “sustainable,” would be akin to hearing an environmentalist marvel about the horsepower in an all-terrain vehicle. It seldom happens. But a new breed of cowboy, like Jones, is changing how ranching is being done in the American West and might – just might – alter the dynamic in the “range wars” that have engulfed the region for more than a half century. Make no mistake: These are not new arrivals carrying out green techniques for the feel-good sake of being green. They are ranchers managing the land in benevolent and environmentally sensitive ways because they think it will help them survive – and make money….
…. intensive management of a ranch’s grasslands. Traditionally, cows are turned out to graze largely unattended on vast open expanses, where they eat the vegetation until it is virtually denuded. This, in turn, can lead to greater dependence on costly hay, as well as antibiotics and pesticides. The Joneses herd cows into more confined areas cordoned off by portable electric fences. Once the grass is chewed down to a certain height, they shift the cattle to another area. The consumed acreage is allowed to rest and replenish, sometimes for a year or more. On a sun-kissed day, Jones pulls out a flowchart showing exactly where Twodot cattle will be grazing over the next seven months….
….Today, after employing Savory’s and other land-management techniques, the Twodot has tripled the abundance of its grasses. The healthier brome has helped the ranch better cope with a chronic lack of rainfall. Plant diversity has flourished, wetlands have improved, and wildlife is thriving. As if on cue, an eagle settles into a nest on a nearby marsh, and two fawns bound through underbrush by a river once trammeled by cattle. “In essence, it’s like having three ranches available to us of comparable size to what we had raising our cows the old way,” says Jones….
Not everyone is so enamored with sustainable ranching. Many old-guard cattlemen believe that worrying about things like wildlife preservation and reviving grasslands detracts from the main objective – to raise cattle in a way that turns a profit. They see the movement as too touchy-feely in philosophy and too dogmatic in practice. They’ll take their risks with controlling predators, raising hay, and using antibiotics and feedlots. Many of them also remain dubious that in the end holistic management can work – that consistent money can be made raising cattle while playing groundskeeper to rangeland. Much of the skepticism may be cultural – a deep-seated resistance to throwing off the way things have been done, and often successfully done, for generations.
Some environmentalists balk at sustainable ranching, too, even though, in theory, it would seem to dovetail with their interests. Part of it is an almost visceral rejection of anything practiced by cattle ranchers. They have spent decades trying to remove cows from public lands because of the harm they believe that private livestock do to the environment. They don’t see a few holistic management techniques reversing years of deleterious practices…..

Earnest, well-meaning environmental messages are supposed to be ineffective relics of a bygone age, when bumper stickers still worked and treehuggers hadn’t realised that self-interest speaks louder than Mother Earth ever could. But don’t put that Save the Whales t-shirt on eBay just yet. In experiments published 12 August in Nature Climate Change, psychologists found that telling people about carpooling’s money-saving benefits seemingly makes them less likely to recycle. In short, appeals to self-interest backfired, accidentally encouraging people to behave selfishly in other areas. …This tension isn’t unique to environmentalism, write Evans and Hahn, but may reflect human nature: Studies show that when people are encouraged to be self-interested, they become less helpful, even if there’s no reason why they can’t be both….
Populations survive despite many deleterious mutations: Evolutionary model of Muller’s ratchet explored (August 10, 2012) — From protozoans to mammals, evolution has created more and more complex structures and better-adapted organisms. This is all the more astonishing as most genetic mutations are deleterious. Especially in small asexual populations that do not recombine their genes, unfavourable mutations can accumulate. This process is known as Muller’s ratchet in evolutionary biology. The ratchet, proposed by the American geneticist Hermann Joseph Muller, predicts that the genome deteriorates irreversibly, leaving populations on a one-way street to extinction. … > full story

Residents in a Cumberland County, N.J., community were left wondering what caused dozens of birds to drop dead from the sky earlier this week.
Residents along Peach Drive in Millville found at least 80 dead birds — mostly red-winged blackbirds — on the ground, having fallen from trees and the sky.
“Crazy — something out of a movie,” said resident Michelle Cavalieri, who saw the birds fall.
The birds caused a bloody mess on roadways in the residential neighborhood.
“They’d get up and try and fly and they were out of control so they’d crash and fall again,” said resident Jim Sinclair. “It was just strange.”

KittyCam” Reveals High Levels of Wildlife Being Killed by Outdoor Cats Washington, D.C., August 6, 2012 A new study of house cats allowed to roam outdoors finds that nearly one-third succeeded in capturing and killing animals. The cats, which wore special video cameras around their necks that recorded their outdoor activities, killed an average of 2.1 animals every week they were outside, but brought less than one of every four of their kills home. Of particular interest, bird kills constituted about 13 percent of the total wildlife kills. Based on these results, American Bird Conservancy and The Wildlife Society estimate that house cats kill far more than the previous estimate of a billion birds and other animals each year…. “If we extrapolate the results of this study across the country and include feral cats, we find that cats are likely killing more than 4 billion animals per year, including at least 500 million birds. Cat predation is one of the reasons why one in three American bird species are in decline,” said Dr. George Fenwick, President of American Bird Conservancy, the only organization exclusively conserving birds throughout the Americas….

III, Peter Kareiva, Mary Ruckelshaus, Bruce A. Stein. 2012. Impacts of Climate Change on
Biodiversity, Ecosystems, and Ecosystem Services: Technical Input to the 2013 National Climate
Assessment. Cooperative Report to the 2013 National Climate Assessment. 296 p.
- Biodiversity and ecosystems are already more stressed than at any comparable period of human history. Climate change almost always exacerbates the problems caused by other environmental stressors including: land use change and the consequent habitat fragmentation and degradation; extraction of timber, fish, water, and other resources; biological disturbance such as the introduction of non-native invasive species, disease, and pests; and chemical, heavy metal, and nutrient pollution. As a corollary, one mechanism for reducing the negative impacts of climate change is a reduction in other stressors.
- Climate change is causing many species to shift their geographical ranges, distributions, and phenologies at faster rates than previously thought. Changes in terrestrial plant and animal species ranges are shifting the location and extent of biomes, and altering ecosystem structure and functioning. These rates vary considerably among species. Terrestrial species are moving up in elevation at rates 2 to 3 times greater than initial estimates. Despite faster rates of warming in terrestrial systems compared to ocean environments, the velocity of range shifts for marine taxa exceeds those reported for terrestrial species. Species and populations that are unable to shift their geographic distributions or have narrow environmental tolerances are at an increased risk of extinction.
- There is increasing evidence of population declines and localized extinctions that can be directly attributed to climate change. Ecological specialists and species that live at high altitudes and latitudes are particularly vulnerable to climate change. Overall, the impacts of climate change are projected to result in a net loss of global biodiversity and major shifts in the provision of ecosystem services. For example, the range and abundance of economically important marine fish are already changing due to climate change and are projected to continue changing such that some local fisheries are very likely to cease to be viable, whereas others may become more valuable if the fishing community can adapt.
- Range shifts will result in new community assemblages, new associations among species, and promote interactions among species that have not existed in the past. Changes in the spatial distribution and seasonal timing of flora and fauna within marine, aquatic, and terrestrial environments can result in trophic mismatches and asynchronies. Novel species assemblages can also substantially alter ecosystem structure and function and the distribution of ecosystem services.
- Changes in precipitation regimes and extreme events can cause ecosystem transitions, increase transport of nutrients and pollutants to downstream ecosystems, and overwhelm the ability of natural systems to mitigate harm to people from these events. Changes in extreme events affect systems differentially, because different thresholds are crossed. For example, more intense storms and increased drought coupled with warming can shift grasslands into shrublands, or facilitate domination by other grass types (for example, mixed grass to C-4 tallgrass). More heavy rainfall also increases movement of nutrients and pollutants to downstream ecosystems, restructuring processes, biota, and habitats. As a consequence, regulation of drinking water quality is very likely to be strained as high rainfall and river discharge lead to higher levels of nitrogen in rivers and greater risk of waterborne disease outbreaks.
- Changes in winter have big and surprising effects on ecosystems and their services. Changes in soil freezing, snow cover, and air temperature have affected carbon sequestration, decomposition, and carbon export, which influence agricultural and forest production. Seasonally snow-covered regions are especially susceptible to climate change as small changes in temperature or precipitation may result in large changes in ecosystem structure and function. Longer growing seasons and warmer winters are enhancing pest outbreaks, leading to tree mortality and more intense and extensive fires. For winter sports and recreation, future economic losses are projected to be high because of decreased or unreliable snowfall.
- The ecosystem services provided by coastal habitats are especially vulnerable to sea-level rise and more severe storms. The Atlantic and Gulf of Mexico coasts are most vulnerable to the loss of coastal protection services provided by wetlands and coral reefs. Along the Pacific coast long-term erosion of dunes due to increasing wave heights is projected to be an increasing problem for coastal communities. Beach recreation is also projected to suffer due to coastal erosion. Other forms of recreation are very likely to improve due to better weather, and the net effect is likely a redistribution of the industry and its economic impact, with visitors and tourism dollars shifting away from some communities in favor of others.
- Climate adaptation has experienced a dramatic increase in attention since the last National Climate Assessment and become a major emphasis in biodiversity conservation and natural resource policy and management. Federal and State agencies are planning for and integrating climate change research into resource management and actions to address impacts of climate change based on historical impacts, future vulnerabilities, and observations on the ground. Land managers have realized that static protected areas will not be sufficient to conserve biodiversity in a changing climate, requiring an emphasis on landscape-scale conservation, connectivity among protected habitats, and sustaining ecological functioning of working lands and water. Agile and adaptive management approaches are increasingly under development, including monitoring, experimentation, and a capacity to evaluate and modify management actions. Risk-based framing and stakeholder-driven scenario planning will be essential in enhancing our ability to respond to the impacts of climate change.
- Climate change responses employed by other sectors (for example, energy, agriculture, transportation) are creating new ecosystem stresses, but also can incorporate ecosystem-based approaches to improve their efficacy. Ecosystem-based adaptation has emerged as a framework for understanding the role of ecosystem services in moderating climate impacts on people, although this concept is currently being used more on an international scale than within the United States.
- Ecological monitoring efforts need to be improved and better coordinated among Federal and State agencies to ensure that the impacts of climate change are adequately observed as well as to support ecological research, management, assessment, and policy. As species and ecosystem boundaries shift to keep pace with climate change, improved and better-integrated research, monitoring, and assessment efforts will be needed at national and global scales. Existing monitoring networks in the United States are not well suited for detecting and attributing the impacts of climate change to the wide range of affected species at the appropriate spatio-temporal scales.

Protected areas allow wildlife to spread in response to climate change, citizen scientists reveal (August 13, 2012) — A new study has shown how birds, butterflies, other insects and spiders have colonized nature reserves and areas protected for wildlife, as they move north in response to climate change and other environmental changes. he study of over 250 species, led by researchers in the Department of Biology at York, is published online by the Proceedings of the National Academy of Sciences (PNAS). The conclusions were based on the analysis of millions of records of wildlife species sent in predominantly by members of the public. The work represents a major new discovery involving collaborators in universities, research institutes, conservation charities, and regional and national government but — crucially –fuelled by ‘citizen science’. Many species need to spread towards the poles where conditions remain cool enough for them to survive climate warming. But doing this is complicated because many landscapes across the world are dominated by human agriculture and development, which form barriers to the movement of species. The mainstay of traditional conservation has been to establish protected areas and nature reserves to provide refuges against the loss of habitats and other threats in the surrounding countryside…. > full story

Most areas of the world experienced higher-than-average monthly temperatures, including most of the United States and Canada. Meanwhile, Australia, northern and western Europe, eastern Russia, Alaska, and southern South America were notably cooler than average. In the Arctic, sea ice extent averaged 3.1 million square miles, resulting in the second lowest July sea ice extent on record.
The equatorial Pacific Ocean continued to reflect neutral El Niño-Southern Ocean (ENSO) conditions in July. However, according to NOAA’s Climate Prediction Center, the El Niño warm ocean phase will likely develop between now and September.

The percentage of the earth’s land surface covered by extreme heat in the summer has soared in recent decades, from less than 1 percent in the years before 1980 to as much as 13 percent in recent years, according to a new scientific paper. The change is so drastic, the paper says, that scientists can claim with near certainty that events like the Texas heat wave last year, the Russian heat wave of 2010 and the European heat wave of 2003 would not have happened without the planetary warming caused by the human release of greenhouse gases. Those claims, which go beyond the established scientific consensus about the role of climate change in causing weather extremes, were advanced by James E. Hansen, a prominent NASA climate scientist, and two co-authors in a scientific paper published online on Monday in the Proceedings of the National Academy of Sciences. “The main thing is just to look at the statistics and see that the change is too large to be natural,” Dr. Hansen said in an interview. The findings provoked an immediate split among his scientific colleagues, however. Some experts said he had come up with a smart new way of understanding the magnitude of the heat extremes that people around the world are noticing. Others suggested that he had presented a weak statistical case for his boldest claims and that the rest of the paper contained little that had not been observed in the scientific literature for years. The divide is characteristic of the strong reactions that Dr. Hansen has elicited playing dual roles in the debate over climate change and how to combat it…

CSIRO oceanographer Dr. Wenju Cai led an international group of researchers in the first definition of the impact of greenhouse gases and resultant climate change on weather patterns produced by the South Pacific rain band. The research was reported in the journal Nature and reviewed at the Eureka Alert web site on August 16, 2012. Cai and colleagues predict more extreme floods and droughts in South Pacific countries as climate change produces more frequent and more severe fluctuations in the South Pacific rain band. The South Pacific rain band is largest and most persistent rain pattern marker in the region, stretching from the equator to Polynesia. The Pacific rain band has been documented to move northward toward the equator as much as 1,000 kilometers (600 miles) producing extreme weather events. The scientists based their predictions on an extensive analysis of the archives of data from the general circulation models submitted for the fourth and fifth IPCC Assessments.
El Nino events have been documented to shift the South Pacific rain band northward producing drought and forest fires in areas of Polynesia and the South Pacific that have never experienced such events before….
Climate and Culture: Abrupt Change and Rapid Response
Continuous, modern day observations of change suggest the Earth System may already be edging towards abrupt climate change, demanding thorough revisions to climate science, models, and action. The global nature of climate change requires that adaptive measures be pursued and shared throughout all world cultures. Although the task of managing the Earth System’s carbon balance appears unapproachable through conventional politics, a wide range of scientific collaborations and community-level ecological restoration efforts are already well underway. In many instances localized environmental renewal initiatives may provide immediate benefits to impoverished regions as well as provide long-term frameworks for climate change adaptation and mitigation.

Restoring Mangroves May Prove Cheap Way to Cool Climate
Found along the edges of much of the world’s tropical coastlines, mangroves are absorbing carbon dioxide from the atmosphere at an impressive rate. Protecting them, a recent study says, could yield climate benefits, biodiversity conservation and protection for local economies for a nominal cost — between $4 and $10 per ton of CO2. These environments, along with other forms of coastal ecosystems such as tidal marshes and sea grasses, have been given the name “blue carbon” to differentiate them from the “green” carbon of other forests, where carbon is absorbed above ground in trees.

Arctic sea ice coverage has been declining for decades, and 2011 set a record for the lowest amount of coverage ever recorded—a record we’re currently threatening to break. Less ice and more open water means the region will soon be available for additional human activity. Shipping companies and cruise lines are already utilizing new routes, taking advantage of the long-sought northwest passage from Europe and North America to Asia. And as soon as next week, Shell Oil could receive the green light to begin drilling up to five new exploratory oil-and-gas wells off the north slope of Alaska. As Big Oil prepares to exploit the emerging resources and access, the fishing industry has chosen to take a very different approach—one the oil companies should heed.
In August 2009 the National Oceanic and Atmospheric Administration formally approved a proposal by the North Pacific Fishery Management Council to ban all fishing activity in the U.S. Arctic except subsistence fishing by Alaska Natives. Members of the council—the majority of which is comprised of fishing industry representatives—voted unanimously to recommend the prohibition. In a remarkably forward-looking move, the body also opted to close the nearly 150,000-square-mile Arctic Management Area (see Figure 1) until adequate scientific fish stock assessments and other data could be collected that would ensure this virgin resource could be managed sustainably.
This move gained the support of environmental organizations such as Oceana, The Ocean Conservancy, and the Pew Environment Group, as well as Alaska’s biggest coalition of fishing industry interests—the Marine Conservation Alliance, which represents more than two-thirds of the state’s groundfishermen and crabbers.
The fishing industry’s approach to management stands in direct contrast to that taken by the oil-and-gas industry and its federal regulators. Shell has led Big Oil’s charge into the Arctic Ocean and is on the cusp of receiving final permits that could allow them to begin drilling operations there as soon as next week. Logic would dictate this means we know more about the science of oil in the Arctic than we do about the science of fish. Not so.
The same lack of knowledge about baseline environmental conditions in the region that has caused fishermen and their regulators to hit the pause button have not slowed the oil industry. While Shell and other oil companies have committed resources to research projects such as the Chukchi Sea Environmental Studies Program, they are not waiting to see data from these efforts before plowing forward with drilling operations…..

The battle against runaway climate change is being lost. The green movement and the energy industry — while engaged in a furious debate on issues from nuclear power to oil sands — are missing the bigger picture. There is little recognition by either side that current policies to reduce carbon dioxide emissions are inadequate for dealing with the threat that they pose. It is the coal-fueled growth of countries like China and India that generates much of these emissions. Unless a cheap, rapidly deployable substitute fuel is found for coal, then it will be next to impossible to safely rein in rising carbon dioxide levels around the world.
Although the green movement might at first see shale gas as an enemy in this fight, it may in fact turn out to be a friend. Broad development of shale gas resources — with proper ecological safeguards — could be the best way to achieve the quick cuts in carbon dioxide emissions that we need to maintain a habitable environment on Earth. The International Energy Agency has made it clear that, under current energy policies, the door is closing on our attempts to contain the carbon-driven rise in global temperatures to within 2 degrees Celsius (3.6 Fahrenheit) by the middle of the century. In fact, worldwide carbon dioxide emissions from burning fossil fuels reached a record high of 31.6 gigatons in 2011. With emissions rising by one gigaton per year, it appears the temperature-increase target will most likely be missed. The shale gas revolution could be the means of blunting the rise of carbon dioxide emissions and give new hope for staying within the 2 degrees Celsius scenario….

California fish hatcheries assailed
The Associated Press via San Jose Mercury News Share
California needs to dramatically reform its fish hatcheries in order to maintain healthy salmon and steelhead populations, according to a major new study. The $2 million study, released by state and federal wildlife agencies, concludes nearly two years of work by a panel of fishery experts. It found, among other things, that the state lacks standard protocols to manage the 40 million salmon it produces each year at eight hatcheries. It also does not do enough field monitoring to fully understand the fate of all those fish. More

The endangered Pacific leatherback sea turtle, large numbers of which are currently feeding on jellyfish along the Pacific coast, is in line to be honored just like the now-extinct California grizzly bear – but hopefully, environmentalists say, with different results.The state Senate voted Monday to designate the giant turtle as the official marine reptile of California. Gov. Jerry Brown now has 12 days to sign into law the enabling legislation, AB1776 sponsored by Assemblyman Paul Fong, D-Cupertino, and most believe that is a virtual certainty. The legislation would declare Oct. 15 Leatherback Conservation Day in California and, it is hoped, publicize the plight of the turtles, which swim 6,000 miles every year to eat jellyfish outside the Golden Gate. “Naming the leatherback sea turtle as our official state marine reptile will demonstrate California’s commitment to protecting leatherback sea turtles, our ocean’s ecosystem, and recognize the education and awareness this official designation… more »

Energy efficient light bulbs continue to be a target of conservatives in Congress. This summer, multiple amendments were approved by House lawmakers trying to prohibit the government from enforcing federal light bulb standards. Republicans falsely claim those standards “ban” incandescent bulbs.
Now, conservative media outlets are seizing on another opportunity to rail on energy efficient bulbs, saying that compact fluorescents are capable of “frying your skin with UVA radiation.” National Public Radio also featured a story last week perpetuating the myth. Where is this claim coming from? A recent study conducted by researchers at Stony Brook University concluded that the response from healthy skin cells to UV emitted from compact fluorescent lamps (CFLs) is consistent with damage from ultraviolet radiation. However, the report’s findings are not new – and there is no cause for alarm….
