Between 1992 and 2017, Greenland lost 3.8 trillion tonnes of ice. This corresponds to a 10.6 mm contribution to global sea-level rise – about seven times faster than expected. The video shows the cumulative change in ice sheet thickness from 1993 to 2019. It also presents the global sea-level contribution from Greenland ice sheet mass change according to the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) study and the IPCC AR5 projections between 1992 and 2100.
These results combine data from multiple satellite missions including ESA’s ERS-1, ERS-2, Envisat and CryoSat missions and the EU’s Copernicus Sentinel-1 and Sentinel-2 missions with regional climate models to provide an up-to-date assessment of changes across the Greenland ice sheet.
