Greenland is some of the world ’s most - distressed substantial land . In late years , it ’s been subject tobizarre fires , and its ice canvass has beencracking upandmelting downdue to rising temperatures . Now , new enquiry adds to the growing list of calamity the secondly - biggest hoard of ice on the satellite faces : cheery skies .
The finding , issue Thursday inThe Cryosphere , show that last summertime ’s record melt was n’t just the result of uttermost heat that turn the ice sheet liquid . Instead , bizarrely cheery skies actually locked in over the island , and the resulting watery fix evince the path that climate change can overlap with other threats , putting the world at risk .

The summer of 2019 was one for the record script . There was the said weird fire on an island largely cover by ice rink . In June , say Methedrine witness ahuge melt spikethat was a predecessor to aneven expectant spikein late July and former August . The latter meltdown saw the island shed an stupefying 12.5 billion slews of crank in the brace of a unmarried day . Here ’s where I could make a comparison , but even that would n’t help you make sensation of how much trash that is . ( in earnest , can you picture 2.5 billion African elephant ? Because I certain ca n’t . )
All tell , the new findings show that Greenland surface mass equalizer — a system of measurement that factors in snow come in and fade ice run low out — dropped a phonograph recording 320 billion metric tons in 2019 equate to the 1981 - to-2010 average . That ’s even worse news when you study the island prior to was already losingsix times more icethan it was in 1980 . All told , 96 pct of the ice canvass ’s surface saw melt in 2019 . And while heat certainly played a part , the fresh research shows that freaky absolved sky amplify the impacts .
The independent gadget driver for the clear sky was a ridgeline of eminent pressure that park itself over the island . While weather patterns commonly move from west to east in the northern hemisphere , the summer 2019 high - air pressure system that helped melt Greenland was tied to the same pattern thatbaked Europe with record - set up heat .
The strong orbit of high pressure fundamentally shunt storms around Greenland , but not over it . Meanwhile , the clear skies avail heat thing up on the primer coat , which in turn helped sustain the high - pressure system and lack of clouds . Of the 92 days last summer , 63 were dominated by high pressure over the ice sheet . It ’s a vicious feedback grummet that we ’ve watch play out in other location , like California during its multiyear drouth .
The press system was essentially like a kid with a magnifying glass — but instead of killing ants , it cooked the ice . The situation was compounded by low snowfall prior to dethaw season , which ordinarily supply a layer of protection . White , fresh snow reflects incoming sunlight , keeping the ice under it from melting . Without that , blow sullied by detritus , wildfire carbon black , and other crud absorb that rut and worsens the whole situation .
While the Modern research does n’t link the persistent cheery sky to clime change , previous research has found that these type of stuck conditions pattern are becomingmore common due to climate change . Regardless of whether climate change play a role in locking in the weirdly clear circumstance over Greenland , it ’s not a phenomenon that climate modeling include . The new newspaper publisher makes the shell that models require to well incorporate these types of weather shape to truly understand just how scupper the ice is .
For me , though , the takeout is the world needs to get off fossil fuels now rather than waiting to find out how bad things could get .
