Polar bears at risk as warming thaws icy home - Yahoo! News: "Time may be running out for polar bears as global warming melts the ice beneath their paws.
Many scientific studies project that warming, widely blamed on emissions of greenhouse gases from burning fossil fuels, could melt the polar ice cap in summer, with estimates of the break-up ranging from decades to sometime beyond 2100.
Bears' favorite hunting ground is the edge of the ice where they use white fur as camouflage to catch seals.
'If there's no ice, there's no way they can catch the seal,' said Sarah James of the Gwich'in Council International who lives in Alaska. 'Gwich'in' means 'people of the caribou,' which is the main source of food for about 7,000 indigenous people in Alaska and Canada."
