Polar Bears Can't Adapt to Melting Arctic, Will Waste Away

Study finds that polar bears' metabolism will not slow enough to survive the increasing scarcity of their food resources.

Polar bears have been one of the species hit hardest by climate change over the last decade, experiencing population declines up to 40 percent in some areas. Even so, scientists have long held out hope the mammals might adapt in some way to their melting Arctic habitat and rebound––or at least stabilize in numbers––as the world continues to warm.

But new research published Thursday in the peer-reviewed journal Science deals a blow to that optimism.

The Deadlier Scourge of Wildfires in an Age of Climate Change

A Q&A with author Kyle Dickman, whose book, On the Burning Edge, explains why wildfire seasons are so bad and getting worse.

Jul 2, 2015

The 19 firefighters who died battling a wildfire in southwest Arizona captured the nation’s attention in 2013, but aside from being the largest loss of firefighters since the Sept. 11, 2001, terrorist attacks and the worst in a wildfire since 1933, it served as a vivid reminder of climate change’s deadly force.
