(CNN) Greenland's ice sheet melted more last year than any year previously recorded, according to a new study, in another sign of the devastating impacts of a warming planet. To put that in comparison, between 2003 and 2016 the ice sheet lost about 255 billion tons of ice on average -- per year. Greenland's ice sheet is the second biggest in the world behind Antarctica's, and its annual ice melt during summer contributes more than a millimeter rise to sea levels every year. In 2019, Greenland's ice sheet lost 15% more ice than the previous record set in 2012, the study found. The report found that the ice sheet will continue to lose mass in response to Arctic warming.
