Short summary
Our study evaluates models' ability to simulate Antarctic regional climate features by comparing available Paleoclimate Modelling Intercomparison Project models to sets of Last Millennium Antarctic proxy-based reconstructions most relevant to the surface mass balance. We later look at their implications for 21st-century sea level rise. The best-scoring model predicts a higher surface mass balance by 2100, which implies stronger mitigation of the ice sheet contribution to sea level rise.
