Scientists have sought to understand Antarctica's contribution to sea level for over 50 years. During this lecture, Professor Matt A King, University of Tasmania, Australia, explains how recent advances in data analysis and computer modelling could show that Antarctica is increasingly contributing to sea-level rise. He also highlights the fascinating things we can learn about our planet from Antarctica from hundreds of miles above Earth's surface to hundreds of miles below.
