Monster heat wave reaches Greenland, bringing rain and melting its ice sheet

It’s been unusually warm in the United States in recent days, with records being set across the country. But it’s been scorching in Greenland, with temperatures as much as 54° above normal, which means above freezing in many places.

And this comes on the heels of new research from NASA’s aptly-named Oceans Melting Greenland (OMG) mission, which finds that the enormous ice sheet is far more unstable than we realized. That’s bad news because the Greenland ice sheet contains enough land-locked ice to raise sea levels by over 20 feet.
