The melting of Greenland is accelerating, with an estimated loss of between 964 and 1735 gigatons of ice per year by 2100 in a scenario of high greenhouse gas emissions (SSP585), according to three regional climate models. This melting will lead to a rise in sea levels of up to one meter, threatening millions of people in coastal areas. New research conducted by the University of Liège and supported in particular by its NIC5 supercomputer will contribute to future IPCC assessments.
