25 years of observations have shown that a quarter of the glaciers of Western Antarctica are unstable

The researchers studied data collected from 1992 to 2017 by several generations of satellites, including

ERS-1, ERS-2, Envisat and CryoSat, which use radar altimeters to measure the height of the ice cover.

Then the researchers compared the data on the change in height from the ice cover of glaciers with the amount of snow that fell in the region during this time, and put the results in the RACMO climate model.

A wave of thinning ice cover spread rapidly across some of the most vulnerable glaciers of the Antarctic, and their loss leads to a gradual rise in the level of the World Ocean.

It was previously reported that the melting of the largestthe Ross Ice Shelf Ice Shelf in Antarctica accelerated due to the heating of the surface layers of sea water in its vicinity. Until now, it was believed that the greatest contribution to the melting of glaciers makes warm water at great depths.
