"A federal judge has thrown out a key section of an Interior Department rule that declared global warming is threatening the survival of the polar bear."

"U.S. District Judge Emmet Sullivan ruled Monday that the Bush administration did not complete a required environmental review when it said the bear's designation as threatened in 2008 could not be used as a backdoor way to control greenhouse gases blamed for global warming.

The Obama administration agreed a year later, saying that activities outside of the bear's habitat such as emissions from a power plant could not be controlled using the Endangered Species Act.

The Center for Biological Diversity, an environmental group that filed a lawsuit over the 2008 rule, said the decision puts the fate of the polar bear back in the hands of the Obama administration and Interior Secretary Ken Salazar."
