FWS (Fish and Wildlife Service) Director Rowan Gould said the 2008 "threatened" listing was made "following careful analysis of the best scientific information, as required by the ESA."

At the time, the service determined the bears weren't danger of extinction, so did not warrant the “endangered” status. The bears were listed as "threatened" because they face serious threats from projected decline in its sea ice habitat due to global warming would result in them likely being in danger of extinction in the foreseeable future.

FWS is "confident it was and is the appropriate status," Gould said.

Listing the polar bear as “endangered” as a result of global warming could open the door to using the Endangered Species Act to regulate greenhouse gases, an outcome the Obama administration has opposed.
