Melting glaciers in Greenland will lead to a 160 cm rise in sea level in 200 years. This is twice the prediction.

Over the past 55 years - from 1961 to 2016 - glaciers around the world have lost more than 9 trillion tons of ice. The most serious blow

came to Alaska - the region lost 3 trillion tons of ice. In second place is Greenland (1.237 trillion tons), followed by the Andes (1.208 trillion tons). The Arctic regions of Russia and Canada lost more than 1 trillion tons of ice each over the same period.

Computer simulations have shown that meltingGreenland's ice cover will lead to an increase in sea level over the next 200 years by 160 cm - whereas earlier climatologists predicted an increase of 88.9 cm.

Having access to satellite observations, weable to fix the surface speed of the entire Greenland ice sheet and see how this ice is melting. We realized that the surface of some large glaciers is melting very quickly - several orders of magnitude faster than their interior.

Earlier, scientists from the University of California found that the ice sheet of Greenland has decreased six times since the 1980s - the rate of ice loss increased from 50 to 286 billion tons per year.
