that's a surprise
March 25, 2019

When glaciers are in the news, things are usually looking worse for the wear. But a new NASA study published on Monday in the journal Nature Geoscience brought some surprisingly good tidings.

The report shows that the Jakobshvan Isbrae glacier in Greenland, which was previously one of the Earth's fastest-shrinking glaciers, is actually growing thanks to cooling ocean waters off the western coast of Greenland.

Jason Box, a Greenland ice and climate scientists who was not part of the study, told The Associated Press that the discovery "was kind of a surprise" given that most glaciologists had gotten used to a "runaway system."

Box added that Jakobshvan Isbrae is one of the most important glaciers in Greenland because it discharges the most ice in the northern hemisphere.

Unfortunately, there is one caveat — the authors of the study said that the growth is most likely temporary. In fact, per The Hill, the discovery may ultimately be bad news because it means that the ocean temperatures play an even greater role in glacial retreats and advances than scientists previously thought.
