Greenland glaciers melt five times faster than 20 years ago

By Johannes Birkebaek

Global warming has increased the speed at which glaciers in Greenland are melting by fivefold over the last 20 years, scientists from the University of Copenhagen said on Friday.

Greenland’s ice melt is of particular concern, as the ancient ice sheet holds enough water to raise sea levels by at least 20 feet (6 meters) if it were to melt away entirely.
