Polar Bears To Be On Threatened List?

The Bush administration wants Polar Bears listed as threatened. Here is the interesting part.

(WaPo) The administration's proposal -- which was described by an Interior Department official who spoke on the condition of anonymity -- stems from the fact that rising temperatures in the Arctic are shrinking the sea ice that polar bears need for hunting. The official insisted on anonymity because the department will submit the proposal today for publication in the Federal Register, after which it will be subject to public comment for 90 days.

Does this mean that the Bush administration finally believes in global warming? After dismissing global warming as some lefty conspiracy against business, this proposal seems to be an admission by the government that global warming IS changing the environment.
