West Antarctic Ice Sheet collapse is under way

The collapse of the West Antarctic Ice Sheet has begun, according to computer models using detailed topographic maps. The fast-moving Thwaites Glacier will likely disappear in a matter of centuries, researchers say, raising sea level by nearly 2 feet.

Greenland melting due equally to global warming, natural variations

Up to half of the recent warming in Greenland and surrounding areas may be due to climate variations that originate in the tropical Pacific and are not connected with the overall warming of the planet. Still, at least half the warming remains attributable to global warming caused by rising carbon dioxide emissions.
