Glaciers disappeared off the coast of Greenland


Glaciers and ice ridges scattered across the highest points of the Greenland coastline will not be able to withstand the current situation and are melting at present, a study released this week showed. Researchers also point out that melting on the island has passed the point of no return for about 20 years, and smaller glaciers are no longer able to reverse ice loss, according to information from Ohio State University.

This study, published in Nature Communications, also suggests that the melting of ice off the coast of Greenland will result in sea level rise by about 1.5 inches by the year 2100 “This investigation revealed the exact reason why the Green Zone’s most vulnerable areas are melting so fast. “The deep layer of snow that normally captures the melted water on the coast filled its capacity in 1997”, the researchers explained.

Information from the University of Utrecht, which also participated in the research, said that in a “healthy” ice ridge, tens of meters of well-compacted snow can absorb water from melted ice in the summer. In winter, this water will freeze again, and the total ice mass will remain more or less stable from year to year.

Still, the rise in temperatures affected the balance of the cycles and the amount of ice that melts is so high that the compacted snow becomes saturated and the new incoming water can no longer be absorbed, heading for the sea.

Glacier expert and Ohio State University scientist, Ian Howat, is “bad news, but there’s no reason to panic” right away.

“The results of the work concern a small part of the ice that is along the coast of Greenland and not the entire region, which represents the second largest amount of ice hidden in the world”, he added.

In addition to the Ohio State University in the USA, scientists from universities in Utrecht and Delft, the Netherlands, Zurich and Friborg, Switzerland, as well as the Geological Survey of Denmark, the Greenland GUS, and the Norwegian Polar Institute
