Global warming brings bad news for polar bears

Global warming brings bad news for polar bears 24 Nov 2010 Polar bears aren't suited for southern diets and their numbers are likely to dwindle as climate change forces them south, a new study has found. Researchers at the University of California, Los Angeles (UCLA) compared polar bears and grizzly bears because, as global warming shrinks the polar bear habitat, polar bears will be forced southward for alternative food sources, where they will be forced to compete with grizzlies. The researchers studied the skulls of polar bears to see how they compare to grizzlies and found that the northern bears aren't suited for the southern lifestyle.
