Several days of unusually warm weather in northern Greenland have triggered (引起)rapid melting.Temperatures have been running around 10 degrees warmer than normal for this time of year,scientists said.

The amount of ice that melted in Greenland between July 15 and July 17 alone—6 billion tons of water per day—would be enough to fill 7.2 million Olympic-sized swimming pools,according to data from the US National Snow and Ice Data Center.Put another way,it was enough to cover the entire state of West Virginia with a foot of water.

For the scientists out on the ice sheet,the warmth has been alarming.“It definitely worries me,”said Kutalmis Saylam,a research scientist at the University of Texas who is currently stationed in Greenland.“Yesterday we could wander around in our T-shirts—that was not really expected.”Greenland holds enough ice—if it all melted—to lift sea level by 7.5 meters around the world.

In 2020,scientists found that Greenland's ice sheet had melted beyond the point of no return.“No efforts to stave off global warming can stop it from eventually breaking down,”said researchers at The Ohio State University.

Aslak Grinsted,a climate scientist,said that they have been trying to get flights into the camp so they can ship out the ice cores they have recently collected.But the warmth is destabilizing the landing site.

“The temperatures we are seeing right now are simply too hot for the ski-equipped planes to land,”Grinsted said.“So we store the ice cores in large artificial caves we have made into the snow to protect it from the heat of the summer.”Scientists took advantage of the abnormal warmth while they were waiting,playing volleyball in their shorts on an ice sheet at the top of the world.

Grinsted referred to the temperatures as a“heat wave”,and noted that the chance of temperatures getting this hot was clearly linked to global warming.
