The Greenland deoxyephedrine sail lost 22 gigatonnes of meth in a individual daytime on July 28 as a Northern Hemisphere heatwave find temperatures reach more than double their seasonal average , Reutersreports . The quantity of water released by the melt was sufficient to submerse the entire state of Florida by 5 centimetre ( 2 inches ) .
As the heatwave persist in , the Danish Meteorological Institute report a record high-pitched temperature of 23.4 ° hundred ( 74.12 ° F ) the watch over Clarence Shepard Day Jr. at Nerlerit Inaat airport , consort toAFP . Considering the average summer temperature in Greenland is only 10 ° C ( 50 ° F ) , such utmost heat has deepen fears about the stability of the Greenland ice sheet .
Second in intensity only to the Antarctic ice sheet , the mass of rooted piss that covers Greenland is currentlymelting faster than at any time in the past 12,000 years , and researchers think it may have alreadycrossed its tipping item , have in mind there is now nothing we can do to bring through it .
According to a recent subject field , the melting of the Greenland ice sheet hascaused sea level to riseby 10.6 millimeters since 1990 . Should it melt completely , worst - case scenarios could see sea levels increase by a astounding 7 meters ( 23 feet ) around the universe .
In direct contrast , the Antarctic ice sheet has so far only contributed 7.2 millimetre to the globose upgrade in sea level , but has the potential to grow an increase of 58 meter ( 190 pes ) should it melt completely .
Two age ago , extreme summertime temperature run across the Greenland trash sheet shrink to its lowest volume since observation start in 1981 , with the expectant single - day thawing case also take place in tardy July 2019 . While last week ’s monolithic thawing did n’t release quite as much piddle as the heatwave of two summers ago , it did affect a large arena , and the on-going effects of the soaring temperature have resulted in an mediocre daily melt of around 8 metric piles per day .
apart from producing a important rise in sea stage , the melt of the ice sheet may also result in large amounts ofmercurybeing pumped into the sea . late enquiry has show that the pee being released by dethaw ice in Greenland is astonishingly full-bodied in the toxic metal . scientist are unsure why this is the cause , with no obvious source of mercury present in Greenland , although they mistrust that it may stanch from lifelike geochemical process .
