Biologists affiliated with the American Museum of Natural History and City College of the City University of New York have found that grizzly bears are roaming into what was traditionally thought of as polar bear habitat -- and into the Canadian province of Manitoba, where they are officially listed as extirpated. The preliminary data was recently published in Canadian Field Naturalist and shows that sightings of Ursus arctos horribilis in Canada's Wapusk National Park are recent and appear to be increasing in frequency.
Looks like someone forgot to tell the bears that climate change is just a conspiracy. Stupid bears!

Maybe Nigel Lawson should go up there and inform them face to face that it's all just a hoax.......

I think grizzly and polar bears are quite closely related, diverging during the Pleistocene. They can produce fertile hybrids and their status as separate species is more a matter of morphology, behaviour and adaptation to different ecological niches rather than much genetic difference.

As the Arctic sea ice goes so will the polar bears' niche.
