Oops, NASA Finds Mantle Plume Melting Antarctica From Below, not ‘global warming.’ Another chink in the global warming scam.
A mantle plume producing almost as much heat as Yellowstone supervolcano appears to be melting part of West Antarctica from beneath.
Researchers at NASA have discovered a huge upwelling of hot rock under Marie Byrd Land, which lies between the Ross Ice Shelf and the Ross Sea, is creating vast lakes and rivers under the ice sheet. The presence of a huge mantle plume could explain why the region is so unstable today, and why it collapsed so quickly at the end of the last Ice Age, 11,000 years ago.
