"echoing earlier arguments by the Bush Administration, Kempthorne repeatedly pointed out that even though the polar bear had become the first animal listed as threatened due to global warming, and despite a clear scientific consensus connecting the rise in man-made greenhouse gas emissions to rapid warming in the Arctic, in no way would the listing open the door to requiring reductions in U.S. emissions as a way to protect the bear."

Crills is at the base of the food chain over there, and the nutrients feeding them dropped significantly due to the main ocean currents slowing down, the consequence is that the population of crills dropped by a hefty 80%! All subsequent form of life in that region is affected by this, polar bears included.

And to not help even more, cold water and the ice covering is the best way to retain Co2 soluble, so the warm up is a really bad news, as it will amplify the emission problem.

The days of the current evolution chain were counted from the first day when man started to use fossil fuels, and I'm just a tad pessimist here.
