Trouble is, this isn't new.

Lead author Andrew Fisher, professor of Earth and planetary sciences at UC Santa Cruz, emphasized that the geothermal heating reported in this study does not explain the alarming loss of ice from West Antarctica that has been documented by other researchers. "The ice sheet developed and evolved with the geothermal heat flux coming up from below--it's part of the system. But this could help explain why the ice sheet is so unstable. When you add the effects of global warming, things can start to change quickly," he said.

They compared the theoretical model with data brought back from Nasa’s missions over the Antarctic, to ensure it was realistic. It led them to believe there was a mantle plume, packed with huge amounts of pressure and heat, beneath the surface. It would have formed 50 million to 110 million years ago, long before the ice sheet itself came into being.
