This Hauntingly Beautiful Image Shows Greenland’s Massive Melt

This image, acquired by one of the Copernicus Sentinel-2 satellites on Aug. 21, 2021, shows meltwaters flowing above the ice cap near Kangerlussuaq in southwest Greenland.

The picture above is gorgeous, however seems could be misleading. It reveals there’s approach an excessive amount of ice is melting in Greenland, and we should always all be involved.

The tranquil, surreal scene was captured by a European Space Agency satellite tv for pc over the weekend. It reveals meltwater swirling over the ice cap within the southwestern a part of the nation. But whereas every part seems calm, the picture is an indication of a future that’s something however.

The melting on the ice cap was triggered by an Arctic warmth wave—the area’s second main one of many summer season. It introduced temperatures in some areas to 32 levels Fahrenheit (18 levels Celsius) hotter than the seasonal common, and likewise brought on raindrops to fall on the National Science Foundation’s Summit Station, a climate observatory roughly 2 miles (3 kilometers) above sea stage, for the primary time in recorded historical past.

The ice soften extent peaked at 337,000 sq. miles (872,000 sq. kilometers) on Sunday, according to the National Snow and Ice Data Center. That’s an space of about half of the ginormous sheet. That’s main, particularly so late within the season. But this meltdown was really barely smaller than the massive soften occasion that occurred in late July, which unfold throughout 340,000 sq. miles (880,595 sq. kilometers). Due to this 12 months’s warmth, the Greenland ice sheet reached its highest most day by day melting charge recorded since 1950, dropping seven occasions extra ice than regular, according to an analysis by University of Liège local weather scientists.

There’s just one different 12 months when a number of soften occasions coated greater than 309,000 sq. miles (800,306 sq. kilometers). That 12 months is 2012 in case you ever should reply a Jeopardy! clue about it. During that summer season, winds lofted massive quantities of soot from wildfires in other parts of the Arctic to Greenland, which drove a meltdown throughout nearly the entire ice sheet surface.

Though the meltwater left behind these occasions is portray stunning footage throughout the ice, the warming is a local weather warning. The Arctic is heating up quicker than another location on Earth. Dark-colored meltwater absorbs extra warmth than ice or snow, so when water swimming pools on the ice, it could possibly create a suggestions loop, spurring extra ice to soften and widening the deep blue ponds. The blue soften ponds seen within the picture are basically dreamy swimming pools of scorching fudge that spell the ice sheet’s break. Rainwater also can quicken the melting, and the pockmarks the rain leaves behind can additional destabilize the sheet. Soot has additionally proven up on the ice sheet with extra alarming regularity, including one other means to soften. Even sunny skies are working towards Greenland’s ice, and all these elements are resulting in long-term harm.

That’s driving sea stage stand up. According to the latest United Nations local weather report, seas are rising quicker than at any level within the final 3,000 years, and ice soften from Greenland and Antarctica’s ice sheets is the primary purpose why. So sure, meltwater ponds over ice caps are beautiful, however the scenes they might create all over the world are grotesque.
