The designation was granted because the species is threatened with extinction because of shrinking sea ice. This makes it the first creature added to the endangered species list primarily because of global warming.
But the department also issued special rules designed to exempt from the law offshore oil and gas drilling in prime polar bear habitat off Alaska's north coast, and cast doubt on whether far-flung conditions, such as emissions from tailpipes, feedlots and smokestacks around the globe, could be directly linked to the shrinking sea ice.
Conservation groups, however, are gearing up to test that premise in court, citing a Supreme Court ruling last year that defined carbon dioxide as a pollutant.
