| America’s Ten Most Imperiled Wildlife Refuges | |
| 5/23 |
National Wildlife Refuges are supposed to shelter countless migratory waterfowl, native mammals, reptiles and amphibians but many refuges themselves are under siege, according to a new report by Public Employees for Environmental Responsibility (PEER). Destructive intrusion onto refuges ranges from industrial activities, such as mining and drilling, to recreational abuse, such as off-road vehicle traffic, but the common thread linking all these threats is political pressure to put the interests of wildlife second. The National Wildlife Refuge System was commissioned by President Theodore Roosevelt in 1903 when he designated Florida’s Pelican Island as America’s first wildlife refuge. Today the system encompasses more than 540 refuges in all 50 states. Based upon interviews with refuge staff, PEER identified the Ten Most Imperiled Refuges in the U.S. The threatened refuges span the nation from Alaska’s Yukon to the Florida Keys:

| Humpback whales make a dramatic comeback | |
| 5/23 |
Once hunted to the brink of extinction, humpback whales have made a dramatic comeback in the North Pacific Ocean over the past four decades, a new study says. The study released Thursday by SPLASH, an international organization of more than 400 whale watchers, estimates there were between 18,000 and 20,000 of the majestic mammals in the North Pacific in 2004-2006. Their population had dwindled to less than 1,500 before hunting of humpbacks was banned worldwide in 1966. Grist link |
| Amazon deforestation on the rise, says Brazil's new environment minister | |
| 5/24 |
The destruction of the Amazon is once again on the rise despite a recent government crackdown on illegal logging, Brazil's new environment minister said on Wednesday. Carlos Minc said official calculations of how much rainforest has been cut down would be released on Monday by the National Space Research Institute. "It will be bad news. It will be data showing an increase in deforestation," Minc said in an interview on Brazilian national channel, Globo TV. Minc took his post last week after veteran rainforest defender Marina Silva surprised the nation by resigning, citing "stagnation" in the fight to preserve the world's largest remaining tropical wilderness. Deforestation in the Amazon declined for three consecutive years until earlier this year, when preliminary satellite data detected a sharp increase. In response, the government sent environmental agents and federal police units to tackle illegal logging in the jungle region. This policy has been met with violent protests as officials shut down dozens of illegal sawmills, leading to seizures of 15,500 tons of illegally logged wood. Earlier this month, the country's ministry of justice said the operation had reduced deforestation by 80% between February and March. link |
| House passes clean-energy tax credits, Calif. waiver | |

| Bay Area initiates first-of-its-kind fee on biz greenhouse-gas emissions | |
| 5/22 | Businesses in nine San Francisco Bay Area counties will pay 4.4 cents for every ton of greenhouse gases they spew, after the district air-quality board voted 15-1 Wednesday to approve the fee. Set to take effect July 1, the fee will affect more than 2,500 businesses; the district estimates that perhaps seven power plants and oil refineries will have to pay more than $50,000 a year, but most businesses will pay less than $1. The fee is modest enough that dramatic emissions reductions are unlikely to occur, but proponents laud the precedent. Businesses were, unsurprisingly, less enthusiastic, expressing concerns about the cost of tracking and reporting emissions, duplication of state efforts to address warming, and the authority of an air-pollution board to regulate greenhouse-gas emissions. The fee is expected to generate $1.1 million in the first year, which will help pay for projects aimed at reducing the region's emissions. |
| The USDA Is Eliminating a Program That Many Groups Rely on to Track Pesticide Use | |
| 5/21 |
Every year the USDA's National Agricultural Statistics Service (NASS) conducts research on pesticide use and risk associated with various crops, such as corn, soybeans, cotton, and wheat, and the body then releases its data files. That data is used by chemical groups, trade groups, public interest groups and government agencies to track pesticide use and safety, and several advocates say it is the only reliable, publicly searchable database of its kind. In 2007, however, the USDA scaled back its data collection, and only gathered information on cotton, apples and organic apples. Now, the USDA has announced it will completely eliminate the program in 2008, due to budget cuts, and won't be collecting any data. This has many people concerned. Letters to the secretary of agriculture have been signed by the various groups who rely on the USDA's information, including public interest groups such as Greenpeace, NRDC, the Organic Center and the World Wildlife Fund, and industry groups such as Syngenta Crop Protection, Inc., Del Monte Foods and the American Soybean Association.

| One in eight bird species may go extinct | |
| 5/19 |
One in eight bird species is threatened with extinction, according to the International Union for the Conservation of Nature. In the latest update of the IUCN's Red List of threatened species, 190 birds are designated "critically endangered"; eight of those were added this year. Sixteen other bird species were also moved to a higher level of threat on the list, while only two found their prospects improved. "Species are being hit by the double whammy of habitat loss and climate change," says Stuart Butchart of BirdLife International, which helped compile the list. The most endangered feathered fauna include the Mallee emuwren, of which only about 100 are left in the wild, and the Floreana mockingbird, which is hanging on with a population of 60. To save them, says Butchart, we need "broad-scale climate-change mitigation measures" and a change in "society's values and lifestyles." Grist link |
| Nanowires may boost solar cell efficiency, UC San Diego engineers say | |
| 5/12 | University of California, San Diego electrical engineers have created experimental solar cells spiked with nanowires that could lead to highly efficient thin-film solar cells of the future. Indium phosphide (InP) nanowires can serve as electron superhighways that carry electrons kicked loose by photons of light directly to the device’s electron-attracting electrode — and this scenario could boost thin-film solar cell efficiency, according to research recently published in NanoLetters. |
| McCain Outlines His Plan to Confront Climate Change | |
| 5/12 |
Republican presidential nominee-in-waiting Senator John McCain of Arizona today offered his plan to combat global warming. Speaking at the Vestas wind turbine factory in Portland, McCain said what America needs is market-based cap and trade system to curb greenhouse gas emissions, mobilize innovative technologies, and strengthen the economy. McCain envisions a cap and trade system that would encompass electric power, transportation fuels, commercial business, and industrial business -- sectors responsible for just below 90 percent of all emissions. Small businesses would be exempt. By 2012, McCain says his plan would return greenhouse gas emissions to 2005 levels, which were 18 percent above 1990 levels. |
| Oxygen-poor ocean zones are growing | |
| 5/2 | By Kenneth R. Weiss.
Oxygen-starved waters are expanding in the Pacific and Atlantic as ocean temperatures increase with global warming, threatening fisheries and other marine life, a study published today concludes. Most of these zones remain hundreds of feet below the surface, but they are beginning to spill onto the relatively shallow continental shelf off the coast of California and are nearing the surface off Peru, driving away fish from commercially important fishing grounds, researchers have found. The low-oxygen, or hypoxic, zones may also be connected to the Pacific coast invasion of the Humboldt, or jumbo, squid. These voracious predators, which can grow 6 feet long, appear to be taking advantage of their tolerance for oxygen-poor waters to escape predators and devour local fish, another team of scientists theorizes. |
| Small cars gaining popularity in U.S. amid high fuel costs | |
| 5/2 |
High gasoline prices and other economic woes have driven car-buyers in the U.S. to purchase smaller, more fuel-efficient vehicles lately. Last month, sales of compact and subcompact cars made up about 20 percent of total sales; in the mid 1990s, small cars accounted for only about one in eight cars sold in the country. Sales of vehicles with four-cylinder engines also outpaced sales of six-cylinder cars. "It’s easily the most dramatic segment shift I have witnessed in the market in my 31 years here," said a Ford sales analyst. Meanwhile, sales of SUVs and trucks are seeing a sharp downward trend this year, with SUV sales plummeting 25 percent so far. Some market watchers are forecasting a continued shift away from big vehicles since gasoline prices are expected to remain high for a long while. "The era of the truck-based large SUVs is over," said the CEO of the biggest auto retailer in the U.S. |
| Pittsburgh beats out L.A. for sootiest U.S. city | |
| 5/1 |
Pittsburgh, Pa., has received the dubious honor of being the U.S. city most well-sooted for short-term particle pollution, topping an annual list put out by the American Lung Association. Los Angeles came in at a surprise second as Pittsburgh became the first non-California city to top an ALA list. "It's not that Pittsburgh has gotten worse," says the association's Janice Nolen. "It's that Los Angeles has gotten better." A little better, anyway: L.A. was still deemed the worst city for ground-level ozone and for year-round particle pollution (Pittsburgh was the runner-up on that list). Overall, some 42 percent of the American population has unhealthy exposure to ozone and/or soot, according to the report. Want to breathe clean air? Fargo, N.D., beckons. |
| Bats in Trouble in Northeast | |
| 4/28 | By Mollie Matteson. Bats have been dying by the thousands recently in the Northeastern United States. No one knows why, and it may be months, perhaps years, before the cause is determined.
Meanwhile, scientists predict that this summer there will be a population explosion of insects, which bats normally eat in large quantities. Greater numbers of beetles and moths could mean severe and costly losses for farmers and timber producers. There could also be bigger swarms of mosquitoes and other biting bugs, which will mean more discomfort for all of us. |
| Mountain pine beetles fueling climate change via tree deaths | |
| 4/24 | Ravenous populations of mountain pine beetles in Canada's forests are contributing significantly to climate change through killing off large numbers of trees, according to a study in the journal Nature. So far, the beetles have killed trees in over 50,000 square miles of forests in western Canada, and hundreds of thousands of square miles in the western United States. "When trees are killed, they no longer are able to take carbon from the atmosphere. Then when dead trees start to decompose, that releases carbon dioxide into the atmosphere," said study coauthor Werner Kurz. The study estimates that by 2020, beetle-killed trees in Canada could release some 270 megatons of carbon dioxide into the atmosphere. "This is the kind of feedback we're all very worried about in the carbon cycle -- a warming planet leading to, in this case, an insect outbreak that increases carbon dioxide into the atmosphere, which can increase warming," said Andy Jacobson of the National Oceanic and Atmospheric Administration. |
| Northwest sea lions granted stay of execution | |
| 4/24 |
Sea lions all set to gobble their last salmon supper at a Northwest dam have been granted a stay of execution by a U.S. appeals court. Judges granted an injunction, requested by the Humane Society, that a lower court had denied last week. It's only a partial victory for the Humane Society, however, as the court did OK the transfer of the whiskery rascals to zoos and aquariums; state officials planned to nab and relocate eight sea lions on Thursday. |
| Over 800 EPA scientists report political interference in their work | |
| 4/24 | More than 800 U.S. EPA scientists reported some form of political interference in their work in the last five years, according to a survey of EPA staff by the Union of Concerned Scientists. UCS sent out some 5,500 questionnaires to EPA scientists and received some 1,580 responses; over half the respondents asserted they had experienced political meddling of one kind or another in their work. Those most likely to report interference worked in offices involved in writing regulations or conducting risk assessments. Industry groups and the White House Office of Management and Budget were cited repeatedly by the EPA scientists as sources of pressure. Rep. Henry Waxman, chair of the House Oversight and Government Reform Committee, sent a letter to EPA head Stephen Johnson yesterday warning of a hearing on the UCS survey results next month. "These survey results suggest a pattern of ignoring and manipulating science in EPA's decision making," Waxman wrote. |
| Panel says link between smog and premature death is clear | |
| 4/22 | By H. JOSEF HEBERT, Associated Press
WASHINGTON - Short-term exposure to smog, or ozone, is clearly linked to premature deaths that should be taken into account when measuring the health benefits of reducing air pollution, a National Academy of Sciences report concluded Tuesday. The findings contradict arguments made by some White House officials that the connection between smog and premature death has not been shown sufficiently, and that the number of saved lives should not be calculated in determining clean air benefits. The report by a panel of the Academy's National Research Council says government agencies "should give little or no weight" to such arguments. AP link |
| All-electric car coming to the U.S. next year | |
| 4/22 | Reasonably priced, all-electric cars are coming soon to a California near you. (And then to the rest of the U.S. before too long.) Think Global, which was sold by Ford Motor Co. to Norwegian investors in 2003, will partner with two venture capital firms to mass-produce the battery-powered Think City in the U.S., starting next year. About the size of a Mini Cooper, the Think City is a two-seater but has room for two more seats for children. It can drive up to 110 miles on a single charge and has a top speed of around 65 miles per hour. It'll be priced under $25,000, meets European safety standards, and is adorable. Oh, and the Think City is 95 percent recyclable and emission-free, natch. |
| Cats and dogs contaminated with chemicals, says study | |
| 4/21 |
Pets are contaminated with higher levels of toxic chemicals than humans are, according to a report from the Environmental Working Group. In a test of the blood and urine of dozens of cats and dogs, researchers found 48 industrial chemicals. The contamination likely comes from such actions as gnawing on plastic toys, sleeping on fire-retardant-covered furniture, frolicking on pesticide-laden lawns, eating potentially mercury-laden pet food, and, of course, all that licking. Researchers point to a recent uptick in animal cancers and hyperthyroidism. "Our animals are trying to tell us something here," says EWG's Bill Walker. Grist link |
| Senate passes one-year extension of renewable-energy tax credit | |
| 4/10 | The U.S. Senate passed an extension of the renewable-energy production tax credit Thursday as part of a bill intended to address the ailing U.S. housing market. The renewable-energy credit provides a per-kilowatt-hour incentive for the first 10 years a renewable-energy project is in operation -- a credit considered to be a vital driver of clean-energy expansion. The credit is worth an estimated $6 billion and will be extended for another year, through 2009, if the legislation makes it past the House of Representatives and President Bush. Homeowners and businesses will also be able to offset up to 30 percent of the cost of solar and fuel-cell equipment under the bill, and homeowners who install efficient insulation, furnaces, and windows will get additional credits. "It would be difficult for taxpayers to find an investment that offers a better return," said Melinda Pierce of the Sierra Club. "This package of incentives will pay us environmental and economic dividends for years to come." |
| Pesticide Spraying in Santa Cruz | |
| 4/13 | State environmental health authorities said Thursday they are unable to determine whether respiratory problems reported by hundreds of citizens in Santa Cruz and Monterey counties in autumn were linked to an aerial spraying against the light brown apple moth.
A 32-page report released by the Office of Environmental Health Hazard Assessment found that the 487 complaints gathered after the spray campaigns were not detailed or consistent. As a result, the analysis was inconclusive. |
| New Forest Rules Inadequate | |
| 4/11 | The U.S. Forest Service has released new regulations for forest management that are remarkably similar to regulations that a federal judge struck down last year. Under the new rules, species' sustainability will not be evaluated individually; instead, the focus will be on overall habitat. A coalition of green groups have sued, saying the rules loosen protections for wildlife. |
| Salmon Season Canceled in CA | |
| 4/11 | For the first time ever, the Pacific Fisheries Management Council has voted to cancel the salmon fishing season off the coast of California and much of Oregon due to exceedingly low populations of chinook salmon in the Sacramento River area. The restrictions apply to commercial as well as recreational fishers; only a catch of 9,000 hatchery-raised coho salmon will be allowed this season by sport fishers off central Oregon. |
| Sonar will kill some marine life but safeguards are adequate, says Navy | |
| 4/04 | Navy training exercises could expose 94,370 marine mammals to behavior-altering sonar frequencies each year, potentially injuring or killing as many as 30, according to an environmental impact statement released Friday by the Navy. But in its 1,796-page report, the Navy sticks with current safeguards for protecting marine animals, not adopting stricter standards imposed by a federal judge earlier this year. Green groups are likely to challenge the EIS in court, continuing a seemingly neverending cycle of litigation and appeals. |

| Two proposed solar projects to boost California's solar capacity by half | |
| 3/27 |
Two large solar-power projects were proposed in Southern California this week that together could provide up to 500 megawatts of power, just over half the state's current solar capacity and enough to provide electricity to about 300,000 homes. One of the projects, proposed by utility Southern California Edison, aims to put solar panels on 65 million square feet of commercial buildings across Southern California. It's expected to cost $875 million and could be completed in five years, pending approval by the state's utility regulators. The other project, to be sited in the Mojave Desert, is a solar thermal power plant proposed by utility Florida Power and Light; Grist link |
| Fewer zero-emission vehicles will be required on California roads by 2014 | |
| 3/27 | California's Air Resources Board has voted to reduce the number of zero-emissions vehicles required to be sold in the state by 2014 from 25,000 to 7,500. It's a hefty reduction, though less dramatic than the recommendation by CARB staff that the requirement be cut to 2,500 vehicles. Not-quite-zero-but-still-relatively-less-emissions vehicles, like plug-in hybrids, will make up the rest of the quotient, the board decided. |
| Protests in Tibet Partially Spurred by Environmental Concerns | |
| 3/18 | Violent protests that rose this week against Chinese rule in Tibet were spurred in part by anger about environmental destruction in the Himalayas, an area that Tibetans consider sacred. A Beijing-to-Lhasa railway opened by the Chinese in 2006 has provided easy access for Chinese miners to the pristine Tibetan highlands, where they've begun digging up copper, iron, lead, and other minerals. Tibetans are also none too happy about a Chinese plan to divert water from melting Tibetan glaciers and funnel it through canals to feed China's Yellow River. Whether China will be able to quell unrest and put on a happy face in time for the already controversy-riddled Summer Olympics remains to be seen. |
| Industry Launches Campaign Against Lieberman-Warner Climate Bill | |
| 3/20 | Energy industry and business trade groups have launched a concerted campaign against the Lieberman-Warner climate bill. The bill, which would establish a cap-and-trade system to reduce U.S. greenhouse-gas emissions, is much less stringent than some other climate bills in Congress, but Lieberman-Warner is so far the only one to pass out of committee; it's scheduled for a Senate vote in June. Industry and business groups are sponsoring a 17-state anti-climate-bill tour to head off the legislation. The centerpiece of the roadshow is an industry-funded study stressing huge job losses and energy price hikes due to the bill. Also this week, some 70 conservative and religious leaders wrote a letter to senators urging them not to support the Lieberman-Warner bill, describing it as "a vain attempt to change global average temperatures." The letter also characterized the bill as economically catastrophic and questioned the reality of climate change, declaring that even if climate change is real, the warming so far is negligible and "may be beneficial" to humans.

| S.F. Oil Spill Updates | |
| 11/30 Update | The Presidio national park has welcomed a group of eco-volunteers to compost a huge pile of human hair mats they used to clean oily San Francisco beaches in the wake of the fuel oil spill earlier this month.
Lisa Gautier, along with a group of surfers, neighbors and guerrilla activists, used the hair mats to soak up oil that had washed ashore when the Cosco Busan container ship sideswiped a tower of the Bay Bridge. They plan to harvest oyster mushrooms on the mats to turn the pile into compost - a process that takes about three months. Now Gautier just needs to wade through some red tape. She needs permission from the owner of the wayward ship to take the collected waste from a storage facility in Oakland and compost some of it in one of the nation's most picturesque parks.

| Ozone case shows Bush meddling in science: watchdogs | |
| 3/14 | President George W. Bush's decision to intervene in setting air pollution standards is part of a longstanding administration pattern of meddling in environmental science, watchdog groups said on Friday.
In cases this week dealing with polar bears, ozone smog and environmental research, groups that monitor these decisions faulted the Bush administration for slighting science in favor of politics. Bush overruled officials of the Environmental Protection Agency to weaken U.S. standards for smog-forming ozone meant to protect parks, crops and wildlife. On Wednesday, the agency tightened a different ozone standard aimed at protecting human health, but not as much as its own scientists unanimously recommended. ENN link |
| World's first aircraft powered by bio-fuel takes off | |
| 3/15 | The world's first commercial aircraft powered partly by biofuel took to the skies today. The Virgin Atlantic 747 took off on route from London Heathrow to Amsterdam using a 20 per cent biofuel mix of coconut and babassu oil in one of its four main fuel tanks. Virgin boss Sir Richard Branson said the "historic" flight was the first step towards using biofuels on commercial flights. But he said fully commercial biofuel flights were likely to use feedstocks such as algae rather than the mix used on today's passenger-less test run.
Sir Richard Branson's Virgin Atlantic 747 was the first commerical aircraft to take to the skies using biofuel. The flight was made in partnership with Boeing, engine maker General Electric, and Imperium Renewables, with the aim of reducing carbon emissions. Environmental groups immediately dismissed the test flight as a "publicity stunt". Campaigners said carbon savings from biofuels, often made from organic materials such as wheat, sugarcane and palm oil, are negligible. And there is rising concern biofuel crops could be competing with food production, damaging the environment and displacing local indigenous populations. Sir Richard insisted his fuel was "completely environmentally and socially sustainable" and does not compete with food and fresh water resources. |
| Alaska Senators Introduce Legislation to Open Arctic Refuge to Drilling | |
| 3/13 | The push to drill in the Arctic National Wildlife Refuge is back on. Alaska Sens. Lisa Murkowski and Ted Stevens have introduced legislation that would allow drilling in the Refuge if oil should hit $125 a barrel for five straight days. (For those keeping track at home, oil prices Thursday hit a record high of $111 a barrel.) "I can't believe that they would do this again; that dog won't mush," says Cindy Shogan of the Alaska Wilderness League, with an admirably Alaskan cliché. A Sierra Club spokesperson postulates that the legislation has neither much support outside Alaska nor enough votes to overcome a filibuster in the Senate. |
| World's Tiger Population Unwell, WWF says | |
| 3/13 | The world's tiger population is doing poorly and may have been halved in the last 25 years, according to the World Wildlife Fund. The group estimates that the global tiger population has plummeted to about 3,500 today from as many as 7,500 in 1982. Habitat destruction and poaching to feed the thriving market in tiger body parts are thought to be the main drivers of the population decline. If China goes ahead with plans to legalize trafficking in tiger parts, the wild tiger population is expected to take an even bigger hit. Conservationists stressed that, while dire, the tigers' situation could improve if governments work to preserve necessary habitat, step up anti-poaching efforts, and work to curb the tiger-parts market. "Tigers are indicators of ecosystem health; they are indicators of forest health," said Sarah Christie, of the Zoological Society of London. "Saving the tiger is a test. If we pass, we get to keep the planet Earth." |
| Southern Baptist leaders urge action on climate change | |
| 3/12 | Over 40 prominent Southern Baptist leaders released a statement Monday urging action against climate change, asserting that "the time for timidity regarding God's creation is no more." The declaration is a notable departure from a statement released after the denomination's 2007 annual meeting that questioned human impacts on climate change. "We believe our current denominational engagement with these issues have often been too timid, failing to produce a unified moral voice," the new declaration says. "Our cautious response to these issues in the face of mounting evidence may be seen by the world as uncaring, reckless, and ill-informed. We can do better." The signatories also urged action on other environmental ills and called on churches to preach about caring for the environment. One of the signatories, Jonathan Merritt, stressed why environmental protection is so important. "[W]hen we destroy God's creation, it's similar to ripping pages from the Bible," he said. |

| Startup Company Makes Thin-Film Solar Cells Via New Process | |
| 3/7 | Solar company Konarka has announced that it successfully developed a new process to manufacture solar cells that could lead to a range of new solar-powered products and applications. The solar cells are made without silicon and are manufactured into a thin, light film via an inkjet printer, which means they don't need to be born in a clean room like traditional silicon cells. One drawback to the new cells is their efficiency: while regular silicon solar cells achieve efficiencies of up to 20 percent, the new cells are only 5 percent efficient, but Konarka says they're likely to be less expensive and much more dynamic. They can be incorporated into plastics and come in a range of different colors, including transparent. |
