[1] Working at the Institute of Environmental Geosciences (CNRS/Université Grenoble Alpes/IRD/Grenoble INP) and Laboratory for Sciences of Climate and Environment (CNRS/CEA/UVSQ). These labs are members of the Observatoire des sciences de l’Univers de Grenoble and Institut Pierre Simon Laplace, respectively.
[2] These estimates are higher than previous ones: the 2019 IPCC Special Report on the Ocean and Cryosphere in a Changing Climate posited that melting of the Antarctic Ice Sheet would account for 3 to 28 cm of sea level rise between 2000 and 2100. However, not only have an insufficient number of studies been conducted, but those available based their findings on simpler models of the interactions between ice, the ocean, and the atmosphere.
