"About 85 percent of Greenland is covered by a massive ice sheet with an area of about 1,736,000 square kilometers and an average thickness of about 1,500 meters. The volume of ice in the Greenland sheet is estimated to be about 2,600,000 cubic kilometers -- | enough ice to raise sea levels by 6.4 meters if it all were to melt. The Greenland ice cap is only about one-seventh the size of the Antarctic ice sheet." Imagine how much sea level would rise if that ice sheet were to melt! PHOTO AND TEXT CREDIT: NASA SCIENCE NEWS |
