U.S. presses BP to stop gushing Gulf Coast oil leak

A huge oil slick caused by an underwater leak continued to creep toward the U.S. Gulf Coast on Monday as the Obama administration pressed energy giant BP Plc to stem the oil gushing from its ruptured offshore well. The direction of the slick has been pushed around by strong winds in the Gulf of Mexico while the likely economic and environmental costs of the accident mounted. President Barack Obama visited affected communities on Sunday, pledging a "relentless relief effort" but keeping the focus on the British oil giant BP. "Let me be clear: BP is responsible for this leak. BP will be paying the bill," Obama said. "We are dealing with a massive and potentially unprecedented environmental disaster."

Obama to visit Gulf Coast to see oil slick first hand

President Barack Obama will visit the U.S. Gulf Coast on Sunday as his administration aims to deflect criticism that it could have responded more quickly to a huge oil spill in the Gulf of Mexico that threatens to become an economic and ecological catastrophe. The incident could ultimately rival the 1989 Exxon Valdez disaster in Alaska, the worst U.S. oil spill ever. Efforts to contain the spill and protect the sensitive coastline continued on Saturday, but were limited due to rough seas kicked up by heavy winds, authorities said.

U.S. pressures BP as Gulf oil slick spreads

The U.S. government pressured energy giant BP to avert an environmental disaster as a huge, unchecked oil spill reached coastal Louisiana, imperiling fish and shrimp breeding grounds and vulnerable wetlands teeming with wildlife. With oil gushing unchecked from a ruptured deepwater well in the Gulf of Mexico off Louisiana, President Barack Obama's administration piled pressure on London-based BP Plc, the owner of the blown-out well, to do more to shut off the flow and contain the spreading slick.

Warmer Arctic needs new rules to limit environmental damage

A new, warmer Arctic cannot continue to operate under rules that assume it is ice-covered and essentially closed to fishing, resource exploration and development and shipping, WWF said as it launched a group of reports on protecting a newly accessible, highly vulnerable environment with profound significance for global climate, the global economy and global security. The International Governance and Regulation of the Marine Arctic reports were launched as Russian president Medvedev visits Norwegian capital Oslo for talks which include arctic issues and just before the Arctic Council meets in Greenland.

Soil Production of C02 May Decline As World Warms

Contradicting earlier studies showing that soil microbes will emit more carbon dioxide as global warming intensifies, new research suggests that these microbes become less efficient over time in a warmer environment and would actually emit less CO2. The research, published in the journal Nature Geoscience, could have important implications for calculating how much heat-trapping CO2 will accumulate in the atmosphere as temperatures rise. Researchers from the University of California, Irvine, as well as Colorado State and Yale universities, found that soil microbes, in the form of bacteria and fungi, rapidly exhale CO2 for a short period of time in a warmer environment.

Shell gets key Alaska permit

Royal Dutch Shell Plc has been granted a long-awaited federal air-quality permit the oil company needs to conduct exploratory drilling this year in Alaska's Beaufort Sea, government officials said late on Friday. The U.S. Environmental Protection Agency issued the permit to Shell to cover air pollutants emitted from the drill ship and fleet of support vessels that the company plans to mobilize to drill two exploratory wells on leases 16 to 22 miles offshore from Alaska's northern coast.

Forecast for Cape Wind, unsettled

A federal advisory panel urged the U.S. Interior Department on Friday to block a $1 billion wind project off Cape Cod opposed by local business leaders and politicians but seen as helpful to the Obama administration's energy strategy. Cape Wind Associates LLC has proposed building 130 wind towers that would soar 440 feet above the surface of Nantucket Sound near the popular Massachusetts tourist areas of Cape Cod, Martha's Vineyard and Nantucket Island.

Sea Lion Pups Starving in California

Starved and emaciated, sea lion pups are beaching themselves along the Pacific Coast. A strong El Nino tropical weather pattern is to blame. Unusually warm sea surface temperatures in the western Pacific are moving east, forcing the sea lions' natural food sources — squid, hake, herring and anchovies — to seek out cooler waters. Adult sea lions have enough fat stored up to survive the resulting food shortage, but their pups aren't so well-equipped. Richard Evans, medical director of the Pacific Marine Mammal Center in Laguna Beach, Calif., tells NPR's Guy Raz that by the time the animals get to his team, they're in the third stage of starvation.

Scotland gets serious about sea power

Scotland has approved ten marine energy projects that leaders predict could provide electricity for one-third of the nation’s homes by 2020 and make Scotland the world leader in wave energy. The government awarded leases to companies to construct six wave energy projects and four tidal projects off the Scottish coast in what experts say would be the first developments of their kind on a large commercial scale. Construction would cost £4 billion ($6.1 billion) and require another £1 billion ($1.53 billion) in government funding to upgrade the national electric grid. But First Minister Alex Salmond said tapping into the resources of Pentland Firth, a strait north of Scotland that is known for its strong tides, can make the country the "powerhouse of Europe."

Science justifies California water limits

Federal limits on water that can be pumped out of a major river delta for California farmers are scientifically justified, a much-anticipated report said on Friday, a finding hailed by environmentalists in the state's epic water wars. But the National Academy of Sciences stopped short of handing a decisive victory to environmental interests over agricultural interests. The academy said further study was required and that threats to Chinook salmon, delta smelt and other endangered fish were not entirely caused by the pumping.
