Book excerpt: The margins of the greenland ice sheet are the leading contribution to global sea level rise, and changes have been noted at many of its marine terminating outlet glaciers. Here we present changes in the rates of surface elevation change along the entire margin of the Greenland ice sheet at 205 marine terminating glaciers between 1978 and 2015. We analyzed an assemblage of multiple surface elevation data sets to assess how rates of surface elevation change are changing at these glaciers. We find that the change in rates of surface elevation loss have increased by 150% to 300% since pre-2000 rates into the 2000’s, following by a 10% to 20% slowdown in current times. We find that these modern rates are significantly different from historic rates, suggesting that current forcings are changing the ice loss mechanics of the GrIS in the 21st century.
