Danish researchers found out that Greenland’s ice shield was exposed to a large-scale melting during the next heat wave when the air temperature rose to ten degrees above seasonal norms. Starting from Wednesday Last week, the shield lost about 8 billion tons of ice per day, which is twice the normal level in the summer. This is reported in a press release on Phys.org.
According to the Meteorological Institute in Denmark, in the north of Greenland, the temperature exceeded 20 degrees Celsius, which is more than twice the normal average summer temperature. The airport is Nerletrite Inaat, located in the commune of serversocos in the east of Greenland, the thermometer columns reached a mark of 23.4 degrees, which became the highest in the period of temperature records. Then the melted volume of ice would have enough to cover the entire state of the water layer of water with a thickness of five centimeters.
At the same time, the beginning of summer in Greenland was relatively cool with snowfall and rains, as a result of which the melting of the glacial cover remains within the historical norm.
Greenland’s ice shield is the second largest over the Antarctica mass of freshwater ice on the planet with an area of almost 1.8 million square kilometers. The melting of ice shields began in 1990 and accelerated since 2000. Mass loss in recent years is about four times more than it was up to 2000. By 2100, the ocean level will rise by 10-18 centimeters, which is 60 percent faster than previously supposed, due to the melting of the Greenland shield. If the ice shield of Greenland completely melts, the ocean level will rise to six to seven meters.
