Greenland's Importance to the World

Jim Folger, National Geographic, June 2010:

Greenland is warming twice as fast as most of the world. Satellite measurements show that its vast ice sheet, which holds nearly 7 percent of the world's fresh water, is shrinking by about 50 cubic miles each year. The melting ice accelerates the warming—newly exposed ocean and land absorb sunlight that the ice used to reflect into space. If all of Greenland's ice melts in the centuries ahead, sea level will rise by 24 feet, inundating coastlines around the planet.
