Going, Going … Gone: Greenland’s Melting Ice Sheet Passed a Point of No Return in the Early 2000s

For 150 years, the Greenland Ice Sheet withstood anthropogenic climate change—each winter, enough snow piled up to balance the ice lost to spring and summer melting. But that all changed 20 years ago, a new study warns, and the glacier’s melting has now hit a point of no return. Even if warming was halted today, the country’s ice would continue to disappear, researchers said.
