The Greenland Ice Sheet, located in the Arctic Circle, is experiencing the most serious ice melting. The melting of ice on the 27th alone was enough to make the entire state of Florida accumulate about 5.08 cm of water.
CNN reported that this is the third major extreme ice melting of the Greenland Ice Sheet in the past 10 years.
According to the Danish Meteorological Agency, on the 27th alone, the Greenland Ice Sheet lost 8.5 billion tons of surface melting ice, which has accumulated 18.4 billion tons since the 25th.
Ted Scambus, a scientist at the National Snow and Ice Data Center in Colorado, said: "This is a very serious melting. On July 27, a large part of the eastern half of the Greenland Ice Sheet melted all the way from the northern end to the southern end, which is very unusual."
Behind this phenomenon is the global warming caused by human-induced climate change, which makes ice melting faster and faster.
According to the Cryosphere journal, the Earth has lost 28 megatons of ice since the mid-1990s, mostly in the Arctic, including the ice sheet of the Greenland Ice Sheet.
According to Lianhe Zaobao, in 2019, about 532 billion tons of ice from Greenland had melted into the sea.
The unusually hot spring that year, coupled with the heat wave in July, caused almost the entire surface of the Greenland Ice Sheet to melt, and the global sea level also rose by 1.5 millimeters permanently.
Experts warn that if the surface of the Greenland ice sheet continues to melt, coastal cities around the world may face storm surge flooding when the extreme climate encounters a large tide.
It is currently estimated that the global sea level may rise by 2 to 10 centimeters before the end of this century.
