Antarctica Is Melting 3 Ways. 1. Global Warming of the atmosphere is melting the ice with higher summertime temperatures. 2. Warming ocean temperatures are melting the ice below the waterline. And 3. Now a huge volcanic plume of hot magma has been discovered below the bedrock of the Antarctic continent.
Antarctica is being rapidly melted from below say NASA.
There is something mysterious and hot lurking beneath the surface of the Antarctic ice.

Now Nasa says that it might have found the source of that strange heating – a “mantle plume” – or upwelling of abnormally hot rock, that lies deep beneath the surface.

The heat is causing the surface of the ice to melt and crack, resulting in rivers and other disruption to Antarctic ice sheet.
