Runoff from Greenland’s melting snow is one of the biggest potential contributors to sea level rise. Scientists usually gauge meltwater runoff by using regional climate models to compare calculations of melting at the surface with estimates of how much water refreezes — whatever water that doesn’t refreeze is considered runoff. But recent research shows that supraglacial rivers flowing over the ice sheet could swell oceans even more than massive icebergs or the drainage from Gr...
