An ensemble of ice sheet model simulations, performed under three main parameter variations, produces a range of glacial behavior across glacial/interglacial cycles. a–c Simulated Pliocene Antarctic esl (equivalent global mean sea-level contribution relative to modern, calculated from the total ice amount in the domain divided by global ocean area). The full model ensemble is shown in (a–c), but model runs are colored by different parameter values: a sensitivity to ocean temperature, b method of scaling the climate forcing methodology, and c hydrofracturing (see the text for parameter descriptions). d Grounded ice sheet configurations for representative interglacial (IG) and glacial (G) time slices for select model members demonstrate the wide range in spatial variability that can be simulated under different sets of parameter values.
