The sensitivity of the Antarctic ice sheet to a changing climate: Past, present, and future
Abstract The Antarctic Ice Sheet (AIS) is out of equilibrium with the current anthropogenic‐
enhanced climate forcing. Paleoenvironmental records and ice sheet models reveal that the …

Global environmental consequences of twenty-first-century ice-sheet melt
Government policies currently commit us to surface warming of three to four degrees Celsius
above pre-industrial levels by 2100, which will lead to enhanced ice-sheet melt. Ice-sheet …
