very nice! Svalbard melts, NASA shared photos

Nation World News, kilat.com- in the summer of 2022, as a result of unusually warm air temperatures melting record across Svalbard. On the ice-covered Norwegian archipelago, abundant meltwater, much of which flows into the ocean, is the latest manifestation of a rapidly changing climate.

Svalbard is located halfway between mainland Norway and the North Pole. About 6% of the planet’s surface is covered by glaciers beyond Greenland and Antarctica, covering more than half of its geographic area.

Before the record thaw, the atmosphere was changed by heating. The glacier has retreated, and the “fern”, a compressed, porous surface layer of ice, has lost its ability to hold large amounts of meltwater. This summer is due to the continuous hot winds coming from the south.

Parts of the archipelago had average temperatures of 1.8 °C (3.2 °F) above normal from May 1 to July 25, 2022. On 17 July, Svalbard experienced the highest ever melt volume due to a warming trend beginning on 15 July. ,

Additional elements also play a role in the record-breaking event. The archipelago’s sea ice is beginning to disappear faster than usual, and in late 2022, open ocean waters are visible. (Sea ice can sometimes persist into late summer.) This allows warm southerly winds to blow directly inland without first cooling by blowing off sea ice.

In addition, there is only little snow in the winter of 2021-2022. As the weather warms, a thin layer of new snow melts quickly, revealing vast expanses of old, darker snow, spruce, and bare snow. This dark surface absorbs more solar radiation than bright, fresh snow, which speeds up melting on long, sunny days. Arctic,

In the past, most of the meltwater would have accumulated in the fir layers, where it would eventually freeze back. This process could help preserve glacier ice by preventing meltwater from entering the ocean. Snowpack Svalbard retained 34% of summer meltwater between 1981 and 2010. Only 8% of the workforce was retained this summer. (NDA)
