Scientists are finding bodies of dead polar bears in the sea near Alaska and in the Arctic. Apparently, the bears are being overcome with exhaustion and starvation as they are forced to swim hundreds of miles in search of food.
"As the ice gets farther out from the shore because of warming, it's a longer swim that costs [the bears] more energy and makes them more vulnerable," said Dr Ian Stirling of the Canadian Wildlife Service.
A comprehensive report published today by a United Nations panel says there is a 90 per cent probability that mankind is to blame for climate change.
The study also projects a 'best estimate' that temperatures will rise by 3°C (5.4°F) above pre-industrial levels by 2100 - the biggest change in one century for thousands of years.

GrrlScientist is an evolutionary biologist, ornithologist, aviculturist, birder and freelance science and nature writer. A native of the Pacific Northwest, she relocated from Seattle to NYC with her parrots after earning a BS in Microbiology (emphasis in Virology) and PhD in Zoology (Ornithology) from the University of Washington. In NYC, she was the Chapman Postdoctoral Fellow at the American Museum of Natural History for two years, pursuing part of her "dream" research project by reconstructing a molecular phylogeny of the parrots of the South Pacific islands. GrrlScientist and her five parrots are currently relocating to Germany, where she will continue writing her blog while also writing a book and learning German. (Meanwhile, her parrots will continue to nibble on her extensive personal library.)

Wow, how did those bears get up there?
It's really sad what's happening to them though.
