I was curious to see what the popluation of the bears has done over the last 30 years or so that global warmingists use to support global warming theory, I didn't find a good worldwide summary with a quick google search. I did however find the following article. If popluation trends in other areas follow those in eastern Canada it would seem to indicate that GW is a good thing for polar bear populations, since they have increased by nearly 3 times over the period in question.

Despite global warming, an ongoing study says polar bear populations are rising in the country’s eastern Arctic region.
Polar bears are the poster animals of global warming. The image of a polar bear floating on an ice floe is one of the most dramatic visual statements in the fight against rising temperatures in the Arctic.
But global warming is not killing the polar bears of Canada’s eastern Arctic, according to one ongoing study. Scheduled for release next year, it says the number of polar bears in the Davis Strait area of Canada’s eastern Arctic – one of 19 polar bear populations worldwide – has grown to 2,100, up from 850 in the mid-1980s.
“There aren’t just a few more bears. There are a … lot more bears,” biologist Mitchell Taylor told the Nunatsiaq News of Iqaluit in the Arctic territory of Nunavut. Earlier, in a long telephone conversation, Dr. Taylor explained his conviction that threats to polar bears from global warming are exaggerated and that their numbers are increasing. He has studied the animals for the Nunavut government for two decades. -
