Understanding Antarctica’s impact on sea level rise
Antarctic bedrock landforms and drainage basins and their estimated potential for global mean sea level rise (in metres). Areas considered particularly vulnerable are highlighted in blue. Source: Australian Antarctic Data Centre, 2024. DOI: 10.26179/q3fx-8p19 Will melting of the Antarctic Ice Sheet (AIS), Earth’s largest ice mass, cause global sea levels to rise by 5 metres, 2 metres or even less…
