Geothermal heating from within the Earth’s core – as opposed to the possibly warming air or sea – has been measured beneath the West Antarctic Ice Sheet for the first time ever. And, we are told, it is “surprisingly high.”
Exactly what the new geothermal heating figures mean for the forecasts remains to be seen, but it is clear that the amount of geothermal heating is a good bit more than scientists had thought. Some of them are still hoping that it’s a fluke result.
It’s all a very confusing picture, then, and to make it worse nobody until now has had any idea how much heat might be reaching the possibly-troubled West Antarctic sheet not from the somewhat warmer seas and atmosphere, but from the rock beneath it. — Lewis Page, The Register, 13 July 2015
