People look on as water from the rising Mississippi River is released through the Bonnet Carre Spillway while washing out a road May 9, 2011 in Norco, Louisiana. The Army Corps of Engineers began redirecting part of the Mississippi River through the spillway today to lower river levels and reduce pressure on levees in order to avoid a catastrophic failure. The water will flow nearly 6 miles north before emptying into Lake Pontchartrain as the Mississippi rises close to the highest level ever upriver in Memphis. (Photo by Mario Tama/Getty Images)

The Greenland ice sheet is a vast body of ice covering 660,235 sq miles, roughly 80% of the surface of Greenland. It is the second largest ice body in the world, after the Antarctic Ice Sheet. Some scientists predict that climate change may be near a "tipping point" where the entire ice sheet will melt in about 2000 years. If the entire 2,850,000 cubic kilometres (683,751 cu mi) of ice were to melt, it would lead to a global sea level rise of 7.2 m (23.6 ft).
