Due to climate change, which caused high temperatures in the Arctic, Greenland lost a huge amount of ice, the melting of which would be enough to cover the US state of Florida by 5.1 cm of water, scientists say.

It was the third-largest loss of ice in Greenland in one day after 1950. Two other records, also made over the past decade, date from 2012 and 2019.
According to scientists, the warm air froze over the Arctic island due to a change in the pattern of atmospheric circulation, noting that even more ice may have been lost.
About 22 gigatons of ice melted on Wednesday alone, of which 12 gigatons flow into the ocean and 10 gigatons are absorbed by the snow, where it could freeze again, said Xavier Fettweiss, a climatologist at the University of Liege in Belgium.
A group of Danish Arctic research institutes, Polar Portal, described it on Twitter as “mass melting”.
Such events can create feedback loops that lead to additional heating and melting in Greenland, said Marco Tedeschi, a climatologist at Columbia University. When the snow melts, it exposes ice or earth, which absorbs more sunlight rather than reflecting it from the atmosphere.
Scientists have estimated that the melting of Greenland’s ice sheet, the second largest on Earth after Antarctica’s ice sheet, has caused global sea levels to rise by 25 percent in recent decades.
Tedeschi and other scientists have warned that the models used to predict future ice loss do not reflect the impact of changes in ice structure on the atmosphere, meaning they may underestimate the future melting of Greenland, which lies between the Arctic and Atlantic Oceans.
At this time, the Arctic is warming faster than other continents of the planet, due to factors such as the disappearance of ice in the Arctic Ocean, which opens the surface of the water, which absorbs solar radiation.
On Wednesday, according to the EU, the air temperature over Greenland caused “concern” when the temperature in the east of the island reached 23.2 ° C.
