The Greenland ice sheet () is a vast body of ice covering , roughly 80% of the surface of Greenland. It is the second largest ice body in the world, after the Antarctic Ice Sheet. The ice sheet is almost long in a north-south direction, and its greatest width is at a latitude of 77°N, near its northern margin. The mean altitude of the ice is . The thickness is generally more than and over at its thickest point. It is not the only ice mass of Greenland – isolated glaciers and small ice caps cover between around the periphery. 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 of ice were to melt, it would lead to a global sea level rise of .
