Scientists have said that Greenland’s melting ice sheet has passed the point of no return.

A new study suggests that even if global warming were to stop today, the glaciers on the island have shrunk so much that the ice sheet would continue shrinking.

“Glacier retreat has knocked the dynamics of the whole ice sheet into a constant state of loss,” study co-author Ian Howat, an earth scientist from Ohio State University, said in a statement. “Even if the climate were to stay the same or even get a little colder, the ice sheet would still be losing mass.”

“The ice that’s discharging into the ocean is far surpassing the snow that’s accumulating on the surface of the ice sheet,” said study lead author Michalea King, a researcher at Ohio State University, according to USA Today.

According to the NOAA, ice loss from the Greenland ice sheet increased sevenfold from 34 billion tons a year from 1992 to 2001 to 247 billion tons a year from 2012 to 2016, reports the website.
