And as NPR's John Nielsen reports, today's listing comes with a caveat.
JOHN NIELSEN: Interior secretaries don't often hold press conferences to announce endangered species listings, but that's what Dirk Kempthorne did today when he officially declared the polar bear a threatened species. Kempthorne said he made the call for three main reasons. First, he said, Arctic sea ice is essential to the polar bears' survival.
DIRK KEMPTHORNE: Second, the polar bears sea ice habitat has dramatically melted in recent decades. Third, computer models suggest sea ice is likely to further recede in the future.
NIELSEN: Kempthorne said he'd been convinced that melting sea ice forecast issued by computer models were both accurate and scary. But, he didn't seem to have much faith in the idea that global warming was behind the melting trend, and he said environmentalists shouldn't plan to use the Endangered Species Act or ESA to force government action on climate change.
KEMPTHORNE: Listing the polar bear as threatened can reduce avoidable losses of polar bears, but it should not open the door to use the ESA to regulate green house gas emissions from automobiles, power plants and other sources. That would be a wholly inappropriate use of the Endangered Species Act. ESA is not the right tool to set U.S. climate policy.
NIELSEN: Kempthorne says that's why he added some unprecedented language to the polar bear listing; it essentially tries to limit the listing's impact on the energy industry. John Kostyack, a climate change expert at the National Wildlife Federation, called it an attempt to run away from the obvious implications of the listing.
JOHN KOSTYACK: If you are a coal plant dodging global warming pollution, you are contributing to the extinction of the polar bear. He's not willing to say that. And so he said, we're going to put out a rule that details every contributor to global warming pollution that we can't make any causal connection to your activity in the loss of sea ice, which is scientifically incorrect. We will never stand the test of time.
