In 2019, Greenland lost twice as much ice as in a normal year

In 2019, the icy island of Greenland broke all previous records for melting ice, leaching 530 billion tons into the sea, The New York Times reports. That loss is nearly double Greenland’s annual average since 2003, and it shatters the previous record of about 460 billion tons from 2012, researchers report this week in Communications Earth & Environment. What’s more, nearly half of the 2019 melting took place in a single month, July, during an unprecedented heat wave. Ice loss can fluctuate from year to year, and this year’s loss so far has been below average. But even cooler temperatures cannot make up for the massive amount of ice lost in warmer years, scientists say.
