After 50 years of disagreement about whether the Antarctic ice sheet is growing or shrinking, advances in computer modelling and data analysis have allowed international climate expert Professor Matt King to estimate Antarctica’s increasing contribution to sea-level rise. Based at the University of Tasmania, as Professor of Polar Geodesy, Professor King’s research includes observing and modelling the Antarctic ice sheet, estimating resulting sea-level change and the changing shape of Earth. Professor King is visiting Victoria University’s Antarctic Research Centre, and the University of Otago.
