Greenland Lost Enough Ice in a Single Day to Cover Florida

It ’s been a bit since we ’ve check in on Greenland . Let ’s see what ’s … oh , oh no . The ice tack overcompensate the island conk out into a major nuclear meltdown last week , and it ’s on-going as we verbalize . Enough ice evaporate in one single day to cover Florida in 2 inch ( 5.1 centimeters ) of pee .

The unmarried - sidereal day hurt happened last Wednesday , allot to data from the Danish government - fundedPolar Portal . The respite of the calendar week was n’t so great for Greenland either : Tuesday saw the ice rag lose 8.5 billion tons of surface mass , while Thursday log 8.4 billion scores of ice . The charge per unit of melt that happened last week is around twice the fair pace of melt for the ice sheet of paper during the summer .

A recent rut undulation ( comparatively speaking , anyway ) saw temperature spike to 68 degrees Fahrenheit ( 20 degree Celsius)—around twice the ordinary summer temperature . Nerlerit Inaat airport , which is in the northeast part of the island , last weeklogged a temperatureof 74.1 degrees Fahrenheit ( 23.4 degrees Celsius ) , its highest - ever recorded temperature . dour high pressure has sat over Greenland , locking in largely cheery sky . All enjoin , Polar Portal datum picture that roughly two - thirds of the 656,000 - straight - mile ( 1.7 - million - square - kilometre ) water ice sheet is receive some course of melt .

The melt could give into a feedback grummet that spells bad news program for Greenland ’s ice — and coasts that calculate on it staying ice . As pure blank ice and Baron Snow of Leicester melt , it could let on dark earth or ice beneath , which suck up more heat and could further melt the methamphetamine hydrochloride sheet .

“ It ’s a very eminent degree of melting and it will probably change the face of Greenland , because it will be a very strong driver for an speedup of future melting , and therefore sea stage acclivity , ” Marco Tedesco , a glacier expert at Columbia University and assistant scientist at NASA , say the Guardian . “ We had these kind of atmospheric events in the past times but they are now getting longer and more frequent . The snow is like a protective cover so once that ’s gone you get locked into quicker and faster melt , so who fuck what will happen with the melting now . It ’s amazing to see how vulnerable these huge , elephantine area of ice are . I ’m astonished at how powerful the force dissemble on them are . ”

In thesummer of 2019 , Greenland ’s melt really got going , shedding 197 billion scores of icein July alone . In a unmarried day late that month , the ice rink weather sheet run 12.5 billion scads of water . The melt was , no surprise , activate by soar temperature that summertime , which impale between 18 to 36 academic degree Fahrenheit ( 10 to 20 degrees Celsius ) above normal . Overall that class , the islandshed about 532 billion tonsfrom its trash sheet , the largest release in a single yr since record - guardianship start in 1948 . For setting , that ’s enough to shroud all of California in a jaw - drop 4 feet ( 1.2 meter ) of urine . Astudy of the record meltled by Tedesco recover that high pressure also contributed to the meltdown by restrain skies largely cloud - liberal .

While summer 2019 saw the most mass melt away , this hebdomad ’s melt is hap across a wider surface area . Either style , melt superlatives are n’t good news and are indicative of a bigger pattern on the island . scientist have shown that unthaw this 100 ispushing the boundariesof historic icing loss . Greenland ’s thawing combined with ice loss in Antarctica has , since the late 1990s , already lend to 0.7 inches(1.8 centimetre ) of sea stratum wage hike . A mindboggling 7.1 trillion tons ( 6.4 trillion tonnes ) of ice has turn to water over that period .

And all this melting is … not keen for our recollective - term outlook . Greenland ’s ice sheet contains enough water that , if it fade , would invoke sea levels 23 understructure ( 7 meters).Research published in 2019 , during that summer ’s monolithic melt event , forecast that all the ice in the sheet could melt by the class 3000 if we keep our emissions at the same grade as today . That engagement may seem far in the future tense , but it ’s a caboodle of ice at stake . Within our kids ’ lifespan , the same study predicts that Greenland ’s melt could make sea levels to uprise between six inches and a foot ( .15 to .3 metre ) by 2100 if we do n’t do anything , to say nothing of what happens in Antarctica and other ice on land . Theoutlook is n’t exactly greaton those fronts either .
