Rising temperatures continue to rage: a massive 110-square-kilometer iceberg has broken off the largest ice shelf in the Arctic.
In northeast Greenland is the largest ice shelf in the Arctic, known as 79N. There climate change is making itself felt strongly: Satellite images have allowed scientists to see that a huge iceberg with an area of 110 square kilometers has broken away.
Experts expected this detachment to occur sooner rather than later. In recent years, average air and water temperatures have been rising due to global warming, and everything indicates that the 79N platform is going to gradually disintegrate.
As explained by the Geological Survey of Denmark and Greenland (GEUS for its acronym in English), the annual changes of this ice shelf are measured from satellite images, where losses of ice mass can be observed. In the last two years, these losses exceeded 50 square kilometers, and since scientists began studying it in total, 160 square kilometers of ice have been shed.
“We should be very concerned about what appears to be a progressive disintegration of the largest remaining ice shelf in the Arctic, because upstream is the only main stream of ice from Greenland, draining 16% of the inland ice reservoir.” says Jason Box of GEUS.
While it is normal for chunks of ice to break off glaciers, only such large areas break off in exceptional circumstances. The problem is that, Since 1980, the air temperature in the area has risen by around 3 degrees, and in the summers of 2019 and 2020 there have been record peaks.
Climate change is going to severely affect the Mediterranean. According to a study, in 100 years the sea level will rise one meter and the temperature will be 5 degrees higher.
Scientists are concerned about the dire consequences of a progressive thaw of Greenland. Research published in Nature last December revealed that Greenland’s thaw has contributed to sea level rise by 1.1 centimeters. According to a study by the University of Lincoln (Great Britain), this phenomenon it could raise sea level by 10 to 12 centimeters by 2100. [Vía: Science Alert]
