Topographic map of Greenland without its ice sheet

The Greenland ice sheet is the second largest ice body globally, after the Antarctic ice sheet, embracing 1.71 million square kilometers (660 thousand sq mi), approximately 79 percent of the cover of Greenland for the last 18 million years. 

The mean elevation of the ice is 2.1 kilometers or 1,3 miles (over 3 km or 1.9 mi at its thickest point). Nowadays, Greenland is losing approximately 260 billion tonnes of ice to the ocean each year. If the whole 2.85 million cubic kilometers (684 thousand cubic mi) of ice were to melt, it would increase the global sea level by 7.42 meters (24.34 feet).

The map below shows a topographic map of Greenland without its ice sheet.
