Here's another reason to use geoengineering to save the Arctic sea ice. The situation is far worse than they say, because the Arctic sea ice "decline by 40%" has already happened! We could even have "decline by 100%" in a few years. They have probably taken IPCC figures as gospel - figures based on modelling which didn't account for the sea ice record retreat in 2005, let alone 2007. And BTW, 2008 probably had a record low volume of sea ice, which could be more important than extent.
There is no way that CO2 emission cuts can save the Arctic sea ice, when the decline is so fast! The Center for Biological Diversity needs to look to us geoengineers to cool the region!! ------ Administration Hauled to Court for Sake of Pacific Walrus After almost 10 months with no response to our petition to protect the Pacific walrus under the Endangered Species Act, the Center for Biological Diversity this week filed suit against the U.S. Fish and Wildlife Service and Secretary of the Interior Dirk Kempthorne. The Arctic-dwelling walrus, whose scientific name entertainingly translates to "tooth-walking sea horse," is dependent on sea ice for mussel-foraging, resting, nursing, and other life activities -- but the rapid melting of that sea ice, caused by global warming, is forcing the species into a land-based existence it can't deal with. Making matters worse, the species' most important foraging grounds are being auctioned off to oil companies. The Pacific walrus's winter sea-ice habitat is projected to decline by 40 percent by mid-century if current greenhouse gas emissions continue. This magnificent pinniped needs federal protection if it's going to survive.

The Center for Biological Diversity sued the U.S. Fish and Wildlife Service and Interior Secretary Dirk Kempthorne on Wednesday for failing to act on a petition seeking protection for walruses under the Endangered Species Act. Walruses are threatened by global warming that melts Arctic sea ice, according to the group, one of the parties that successfully petitioned to list polar bears as threatened. The group also has filed petitions to protect Arctic seals. The walrus petition was filed in February. The Fish and Wildlife Service was required by law to decide by May 8 whether the petition had merit, which would trigger a more thorough review and a preliminary decision after 12 months. The agency missed the deadline. Rebecca Noblin, an attorney for the Center for Biological Diversity, said the delay would harm walruses. "Every day that goes by without protecting the walrus, we're emitting more greenhouse gases, accelerating the ice melt," Noblin said. "In addition to the climate change, the other main threat is oil and gas development that continues to go forward without any consultation regarding walrus," she said. Fish and Wildlife spokesman Bruce Woods said Wednesday the agency anticipates making a decision on the petition soon but has limited resources. Decisions on endangered species listings are driven by litigation, he said, forcing the agency to rank actions by court order rather than species need. Global warming is blamed for Arctic sea ice shrinking to record low levels. The National Snow and Ice Data Center said summer sea ice in 2008 reached the second lowest level, 1.74 million square miles, since satellite monitoring began in 1979. The loss was exceeded only by the 1.65 million square miles in 2007. Like polar bears, listed as a threatened species in May, walruses depend on sea ice to breed and forage. Walruses dive from ice over the shallow outer continental shelf in search of clams and other benthic creatures. Females and their young traditionally use ice as a moving diving platform, riding it north as it recedes in spring and summer, first in the northern Bering Sea, then into the Chukchi Sea off Alaska's northwest coast. Sea ice in the Chukchi Sea, shared with the Russian Far East, for the last two years receded well beyond the outer continental shelf over water too deep for walruses to dive to reach clams. In the fall of 2007, herds congregated on Alaska and Siberia shores until ice re-formed. According to the Center for Biological Diversity, warming sea temperatures and sea ice loss may also be reducing walrus prey at the bottom of the ocean. The group hopes a listing could slow plans for offshore petroleum development. Oil companies in February bid on 2.7 million acres in the Chukchi Sea. Other lease sales are planned. The Fish and Wildlife Service, along with its Russian counterparts, has nearly completed a comprehensive population count of walruses. The numbers are anticipated in the coming weeks, possibly by the end of the year, Woods said. On the Net: a.. Center for Biological Diversity: http://www.biologicaldiversity.org b..
