Polar bears and climate change

The US government made a rare acknowledgment of the existence of climate change yesterday when it called for greater protection for polar bears. The proposal was to classify polar bears as officially 'endangered', thereby limiting any actions by the US which would harm polar bears or their habitat.

The US proposal came as a result of concerns that the Arctic ice cap is shrinking due to global warming. As US Interior Minister Dirk Kempthorne pointed out;

Polar bears are one of nature's ultimate survivors, able to live and thrive in one of the world's harshest environments. But we are concerned the polar bear's habitat may literally be melting.

But they still won't agree to CO2 emissions reductions...
