Discover more about our planet with the Earth from Space video programme. In this special edition, Andrew Shepherd from the University of Leeds and Erik Ivins from NASA's Jet Propulsion Laboratory join the show to discuss our planet's polar ice sheets.

Their new research shows that melting of the Antarctic and Greenland ice sheets has contributed 11.1 millimetres to global sea levels since 1992.
