The Greenland ice sheet is adversely affected by climate change. In addition to the large ice sheet, smaller ice caps (such as Maniitsoq and Flade Isblink) as well as glaciers, cover between 76,000 and 100,000 square kilometres (29,000 and 39,000 sq mi) around the periphery. The average thickness is about 1.5 km (0.9 mi) and over 3 km (1.9 mi) at its thickest point. The ice sheet is almost 2,900 kilometres (1,800 mi) long in a north–south direction, and its greatest width is 1,100 kilometres (680 mi) at a latitude of 77°N, near its northern margin. It is the second largest ice body in the world, after the Antarctic ice sheet. An acronym, GIS, is frequently used in the scientific literature. It is sometimes referred to as an ice cap, or under the term inland ice, or its Danish equivalent, indlandsis.
The Greenland ice sheet ( Danish: Grønlands indlandsis, Greenlandic: Sermersuaq) is a vast body of ice covering 1,710,000 square kilometres (660,000 sq mi), roughly near 80% of the surface of Greenland.
