As Greenland Melts, Where’s the Water Going?

"In the summer of 2015, two New York Times journalists joined a team of researchers in Greenland that was conducting a unique experiment: directly measuring a river of meltwater runoff on the top of the ice. Now, the scientists have published the results of that work. A key finding — that not as much meltwater flows immediately through the ice sheet and drains to the ocean as previously estimated — may have implications for sea-level rise, one of the major effects of climate change. The scientists say it appears that some of the meltwater is retained in porous ice instead of flowing to the bottom of the ice sheet and out to sea. ..."
