This manuscript investigates the Amundsen Sea region in West Antarctica. The region has been the focus of numerous studies in recent years since the glaciers of the Amundsen Sea are a major source of uncertainty for global sea level rise projections. In this study, the authors use ice-sheet model simulations to investigate the region's response to climate change (specifically, scenarios RCP8.5 and Paris2C). Their results indicate that the region will have contributed approximately 19 mm of sea-level rise by 2100. The authors do not find any indication of rapid retreat or an unstable calving front. Although the ice shelf area significantly decreases in their model simulations, this has little effect on the ice dynamic mass loss. Thus, the manuscript results indicate that by the year 2100, the sea-level contribution from the Amundsen Sea area is almost an order of magnitude less than those estimated by previous studies.

The study presents a highly relevant, large new data set and a related analysis on ground temperatures in the central Andes.
