Abstract Numerical experiments are performed for the Antarctic ice sheet to study the sensitivity of the ice volume to variations in the area of grounded ice and to changes in the climate during the most recent deglaciation. The effect of the variations in the grounded area is found to be the major source of changes in the ice volume, while the effect of climate change was minor. The maximum possible contribution of the ice- volume change to sea-level rise during the deglaciation is estimated to be 36 m, which covers most values estimated in previous studies. The effect of the advance of the ice- sheet margin over those regions not connected to the major ice shelves contributes one- third of the total ice-volume change, which is comparable to the effect of the grounding of the Filchner-Ronne Ice Shelf and the contribution of the Ross and Amery Ice Shelves together.
