Antarctica may appear remote but its ice sheet is deeply connected to the global climate
system. It stores enough ice to raise global mean sea level (GMSL) by several tens of
metres, influences ocean circulation worldwide, and plays a central role in the energy
balance of the Earth. Changes occurring around Antarctica therefore have consequences
far beyond the polar region, affecting ecosystems, coastlines, and societies across the
globe. By way of comparison, the other Earth’s current ice sheet, that of Greenland,
contains a quantity of water that is capable of raising global sea level by several metres.
