New York, March 19 (TIWN) During the exceptionally warm Arctic summer of 2019, Greenland lost 600 billion tonnes of ice, enough to raise global sea levels by 2.2 millimetres in two months, new research has found.

“We knew this past summer had been particularly warm in Greenland, melting every corner of the ice sheet," lead author Isabella Velicogna, senior project scientist at NASA’s JPL and a professor at University of California, Irvine, said in a release. "But the numbers really are enormous."
