On the way home from his Asia trip, George Bush should do a stop-over in Alaska. He needs to talk the people at the USGS Alaska Science Center about what global warming is doing to the state. Bush is averse to science, but maybe they could show him some pictures or some dead polar bear carcasses -- anything to get him to know global warming is real:
Polar bear cubs in Alaska's Beaufort Sea are much less likely to survive compared to about 20 years ago, probably due to melting sea ice caused by global warming, a study released on Wednesday said.
The study, published by the U.S. Geological Survey, estimated that only 43 percent of polar bear cubs in the southern Beaufort Sea survived their first year during the past five years, compared to a 65 percent survival rate in the late 1980s and early 1990s.
"The changes in survival of cubs are very dramatic," said the study's author Steven Amstrup, polar bear project leader for the USGS Alaska Science Center.
