Better measurements unlock new ice sheet mass loss estimates

Abstract

Understanding the dynamics of the world's glaciers is integral to predicting global sea level rise in response to climate change. Greenland's rapidly shrinking ice sheet is a major factor of future sea level rise, but scientists are still unsure how much each component of the ice sheet's changes—surface accumulation, melting and runoff, and changes in ice discharged from the outlet of the glaciers draining into the ice sheet—is contributing to sea level rise.
