WASHINGTON (AP) — A major Greenland glacier that was one of the fastest shrinking ice and snow masses on Earth is growing again, a new NASA study finds.
The Jakobshavn glacier around 2012 was retreating about 1.8 miles and thinning nearly 130 feet annually. But it started growing again at about the same rate in the past two years, according to a study in Monday's Nature Geoscience . Study authors and outside scientists think this is temporary.
Box, who wasn't part of the study, said Jakobshavn is"arguably the most important Greenland glacier because it discharges the most ice in the northern hemisphere. For all of Greenland, it is king." The water in Disko Bay, where Jakobshavn hits the ocean, is about 3.6 degrees cooler than a few years ago, study authors said.
