The Greenland Ice Sheet covers 80 percent of the island and has developed over many thousands of years, with layers of snow compressed into ice.
The dome of ice rises to a height of 3,000 meters and the total volume of the ice sheet is approximately 2,900,000 cubic kilometres, which would raise global sea levels by 7 meters if it melted entirely, according to the Polar Portal website.
