Abstract: At present the Pine Island Glacier in West Antarctica is thinning and its grounding line has retreated. This work uses three ice-flow models to investigate the stability of the glacier and finds that the grounding line could retreat a further 40 km, which is equivalent to a rise in sea level of 3.5–10 mm over a 20 year period.
