According to them, this may cause a sharp rise in sea level in the coming decades due to the sliding of land glaciers into the ocean, reports Nature Communications.

"The glaciers of northern Greenland have enough volume and mass to increase the sea level by 2.1 m. So far, they remain stable due to the fact that ice shelves keep them from sliding into the sea,” said scientists from the University of Grenoble in France.

It is worth noting that they studied the conditions of the eight largest ice shelves that surround the northern part of Greenland. So far, these ice masses are considered relatively stable when compared with their southern neighbors, which have been actively decreasing in area and volume in recent decades and are losing twice or three times as much mass as the northern glaciers.
