"Melting of the world’s biggest ice sheet would cause catastrophic sea level rise, but can be avoided with fast climate action".

"The fate of the world’s biggest ice sheet rests in the hands of humanity, a new analysis has shown. If global heating is limited to 2C, the vast East Antarctic ice sheet should remain stable, but if the climate crisis drives temperatures higher, melting could drive up sea level by many metres.

The East Antarctic ice sheet (EAIS) holds the vast majority of Earth’s glacier ice. Sea levels would rise by 52 metres if it all melted. It was thought to be stable, but is now showing signs of vulnerability, the scientists said.

The EAIS is far larger than the West Antarctic ice sheet (WAIS), which hosts the so-called “doomsday” Thwaites glacier, which has lost significant stability. Total loss of the WAIS would cause 5 metres of sea level rise."
