Greenland ice sheet contribution to 21st century sea level rise as simulated by the coupled CESM2.1‐CISM2.1
The Greenland Ice Sheet (GrIS) mass balance is examined with an Earth system/ice sheet model that interactively couples the GrIS to the broader Earth system. The simulation runs from 1850 to 2100, with historical and SSP5-8.5 forcing. By the mid-21st century, the cumulative GrIS contribution to glob...
