Antarctica's warm underbelly revealed

from BBC News

Thank you Bill Pearson, P.Geo. for submitting the following article. This is the best map yet produced of the warmth coming up from the rocks underneath the Antarctic ice sheet. This "geothermal heat flux" is key data required by scientists in order to model how the White Continent is going to react to climate change. If the rock bed's temperature is raised, it makes it easier for the ice above to move. And if global warming is already forcing change on the ice sheet, a higher flux could accelerate matters. more
