Melting of the Greenland ice sheet mapped

16 September 2009

Melting of the Greenland ice sheet mappedWill all of the ice on Greenland melt and flow out into the sea, bringing about a colossal rise in ocean levels on Earth, as the global temperature rises? The key concern is how stable the ice cap actually is and new Danish...
