The thinning of the Greenland ice sheet turned out to be more dangerous than previously thought

Parts of Greenland's ice sheet are thinning inland, according to a new study.

much more active than previously thought. This means that sea levels will reach a higher level by the end of this century.

Previously, scientists mainly studied the edges of the iceGreenland Shield using satellite data. However, the authors of the new study looked further - more than 100 km from the coast. It turned out that the thinning of the Greenland coast extends 200–300 km deep into the ice sheet.

It is noteworthy that scientists have studiedthe northeastern part of the giant ice sheet. However, experts believe that similar processes are observed in other regions of Greenland and another ice sheet of the Earth, in Antarctica.

The data is causing concern among scientists. Rising sea levels are already threatening millions of people who live along the coast. In the coming decades and centuries, they may find themselves under water.
