So, global warming might actually have led to the evolution of polar bears. And, apparently:
…polar bears have already survived a global warming that affected the northern hemisphere from 130,000 to 115,000 years ago, when the Greenland ice sheet and the Arctic ice cap were smaller than now.
Global warming zombies, however, had to spin the story:
Professor Chris Stringer, of the Natural History Museum in London, said: ‘Living through a warm period back then does not mean polar bears are resilient to climate change now.’
Right.
