Greenland is known for glaciers, but the island has been melting at unprecedented speeds and fires have been reported over the past month.
Scientists did not expect Greenland to melt at this pace for another 50 years. By the last week of July, melting has reached the level predicted by climate models for 2070 under the most pessimistic scenario, reported Science Alert.
Greenland's ice sheet lost 12.5 billion tonnes of ice on August 1, the most a day since researchers began measuring melting ice in 1950, the Washington Post reported.
Dramatic melting suggests that Greenland's ice cover is approaching a turnaround that could irreversibly lead to complete extinction.
If that happens, the catastrophic rise in sea level will devour coastal cities around the world.
Arctic ice melting season begins each year in June and ends in August, with the melting peak recorded in July.
However, the speed of melting ice in Greenland this year has surpassed the records.
From July 30 to August 3, melting has been recorded on 90 percent of the surface of Greenland with 55 billion tonnes of water discharged over five days.
Similarly, above-average melting has been registered in Switzerland, glaciers have lost 800 million tonnes of ice there during heat waves in June and July.
Alaska also saw record melting ice in July.
