Scientists hope new research linking polar bear deaths and climate change will help protect arctic wildlife

For 15 years, a federal standard has prevented regulators from considering planet-warming emissions when enforcing the Endangered Species Act, a federal law aimed at protecting species at risk of extinction. But now, researchers at the University of Washington and Polar Bears International believe they’ve found a way to close that loophole. It's a finding that they hope will actually protect polar bears — the poster children for climate change — for real this time.
