The good news and the bad news about polar bears:

Polar bears are a potentially endangered species living in the circumpolar north. They are animals which know no boundaries. They pad across the ice from Russia to Alaska, from Canada to Greenland and onto Norway's Svalbard archipelago. Biologists estimate that there are 20,000 to 25,000 bears with about sixty percent of those living in Canada.

The main threat to polar bears today is the loss of their icy habitat due to climate change. Polar bears depend on the sea ice for hunting, breeding, and in some cases to den. The summer ice loss in the Arctic is now equal to an area the size of Alaska, Texas, and the state of Washington combined.

At the most recent meeting of the IUCN Polar Bear Specialist Group(Copenhagen, 2009), scientists reported that of the 19 subpopulations of polar bears, eight are declining, three are stable, one is increasing, and seven have insufficient data on which to base a decision—this is a change from five that were declining in 2005, five that were stable, and two that were increasing. During the meeting, delegates renewed their conclusion from previous meetings that the greatest conservation challenge to the polar bear is ecological change in the Arctic related to climate warming.

On May 14, 2008, the U.S. Department of the Interior reclassified the polar bear as a Threatened Species under the Endangered Species Act, citing concerns about sea ice loss. Russia lists the polar bear as a species of concern.
