Good news on polar bear critical habitat proposal

We're pleased that US Fish and Wildlife Services proposed designating 128 million acres of critical habitat for the imperiled polar bear. And really, we want to just be happy, and pretend like it's all going to be OK. But, let's face it: Unless we stop carbon emissions, 200,000 square miles of habitat won't be enough- it will be mostly underwater. 93 percent of the designated area is (currently) sea ice.
