Large magma plume in Antarctica

Imagine drifting over Antarctica's icy expanse. A white continent extends below you, and it's smothered in enough frozen water to drown every coastline in the world in a 216-foot (66 meters) wave if it were to melt. But scientists now believe that, deep beneath almost 1.2 miles (2 kilometers) of ice and a relatively thin slice of rocky crust, one region of the frozen continent hides a column of red-hot magma, straining toward the surface, according to a new study.

Usually, magma nears the surface only at the edges of tectonic plates. And West Antarctica's Marie Byrd Land, where the plume is suspected to exist, is far from any such border regions. However, there are places in the world where magma reaches toward the surface far from any tectonic border regions, NASA scientists said in a Nov. 7 statement. Yellowstone National Park is one. Hawaii is another. All that magma pushes against the crust in those parts of the world, causing it to bulge and pumping heat up through the ground.

That heat offered scientists the first clues that the Antarctic plume exists.

could this be the reason for Antarctica's melting glaciers ? / sea temperatures a rising < so claimed ... or is it (man made) global warming ?

The Siberian Traps incident happened when the Siberian Craton was parked over the rift that is now Iceland. Since the crust floats and drags cratons and whole continents with it  magma plumes wind up in strange places. It could be a old crust fault.

 

Global warming is man made. PERIOD!
