The rate at which ice discharges from the great ice sheetsinto the oceans is presently the greatest source of uncertaintyin projections of global mean sea level rise. Reducing theuncertainty of ice sheet behaviour is important since the twogreat parts of Antarctica the East and West Antarctic icesheets hold around 70 per cent of the worlds fresh waterand more than 90 per cent of its ice. If the ice sheet meltedcompletely, global mean sea level would rise by about60 metres, although the likelihood of this occurring over thenext two centuries is low.
