Landmark study quantifies the impact of green
Scientists have, for the first time, quantified a direct link between greenhouse gas (GHG) emissions and polar bear survival. 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. The approach outlined in the paper connects the dots between greenhouse gas emissions, the number of ice-free days caused by specific amounts of emissions, and polar bear surviva...
