We use the cliched term “glacial pace” to describe something that moves really slowly. But new research shows that Greenland’s glaciers may actually be moving more rapidly than we thought thanks to rushing rivers on their surface.

In 2015, a group of scientists took a NASA-funded expedition to the Russell Glacier in western Greenland to camp out on the melting ice. There, they observed the surface of the ice as well the complicated processes taking place under the Greenland ice sheet, which dictate how quickly glaciers slip into the ocean. Getting handle on what’s happening is vital because more ice falling into the ocean raises sea levels, threatening coasts everywhere. In a study published in Geophysical Research Letters on Monday, two of the expedition’s researchers explain their findings.
