Cancun climate change summit: global warming killing polar bears

Cancun climate change summit: global warming killing polar bears --Polar bear cubs are starving as a result of climate change, according to experts, because global warming is causing the sea ice to melt. 09 Dec 2010  New video footage shows a mother bear and two cubs in Hudson Bay, Canada, desperately searching for food. One of the cubs experiences seizures in the video, and both cubs died within two days of the filming. Kassie Siegel, director of US research group Center for Biological Diversity, said the bears are dying as a result of climate change. "Although it’s difficult to watch, this video is an important document of the terrible cost of climate change denial and inaction," she said. "Global warming isn’t a crisis that’s decades away. It’s here now. The sad truth is that polar bears are already starving as global warming melts the Arctic."
