Bozeman, Montana – August 31, 2023 – In a new paper, scientists with Polar Bears International, the University of Washington, and the University of Wyoming have, for the first time, quantified a direct link between greenhouse gas (GHG) emissions and polar bear survival. Published today in Science, the report, “Unlock the Endangered Species Act to address GHG emissions,” provides a template for estimating the demographic impact of proposed GHG-emitting actions on polar bears—overcoming a loophole in the Endangered Species Act (ESA) that has historically blocked climate considerations.
