Copenhagen Feb 2 (BUS): Melting Greenland’s ice sheet by 1.2 cm has contributed to global sea level rise in less than 20 years, according to the monitor.
The Greenland ice sheet has lost about 4,700 gigatons since measurements began in April 2002, enough to inundate the entire United States by half a meter, satellite data from Grace and Grace-FO programs through August 2021 show.
The data indicates that the ice is melting, especially on the west coast of Greenland, the Danish portal Polar Portal tweeted this week. One gigaton is equivalent to 1 billion tons.
The Greenland ice sheet covers four-fifths of the total area of the largest island on Earth. The German news agency (dpa) said that the ice sheet in Antarctica is the only one larger.
Polar Portal is a platform where Danish Arctic research institutions present their findings on the state of Greenland’s ice sheet and sea ice.
Greenland is largely self-governing, but officially belongs to Denmark. The island is particularly affected by climate change, as the Arctic has already warmed more than any other region on Earth.
