According to the associated press, scientists have found that in the past 2019, the melting of the ice sheet in Greenland, which is under the jurisdiction of Denmark, has reached a record high. < / P > < p > a new study shows that, affected by global warming and other factors, in 2019, there will be 586 billion tons of ice sheet melting in Greenland, which is 1.25 meters higher than California, the third largest state in the United States, which is the highest since relevant records. The previous record was 511 billion tons in 2012. INGO Sassen, a geoscientist at Helmholtz Center for polar and ocean research, Helmholtz: This is the largest melting of the Greenland ice sheet since the record was in 2012, which led to a large-scale melting of the ice sheet in summer. Now, this number has reached a new high in 2019. According to a press release issued by the Danish Meteorological Institute on the 18th, an international research team participated by the Danish Meteorological Institute analyzed the melting data of ice sheet in Greenland in the past 30 years, and found that if the current rate of climate warming is maintained, the Greenland ice sheet will continue to melt, and the global sea level will rise by at least 10 cm around 2100. The researchers believe that if Greenland ice sheet melts completely, it will cause global sea level to rise by 7 meters. The melting ice sheet in Greenland reflects the vulnerability of polar regions to climate change, and human beings must do something to limit global warming, according to researchers at the Danish Meteorological Institute.
