Before leaving this little diversion I found this

Antarctica's warm underbelly revealed

"
The map was made by researchers at the British Antarctic survey and is published in the journal Geophysical Research Letters.
"The heat coming from the Earth's interior is important to understand the overall conditions that control the dynamics at the base of the ice sheet and hence the ice flow,” explained Yasmina Martos, currently affiliated to the US space agency.
"If this heat flux is elevated, the ice base can melt and produce water that acts as a sliding film.
"One result of our study is that the heat flux is higher underneath West Antarctica, where more ice is currently melting, than underneath East Antarctica.
"Even a little melting at the base helps the ice sheet to slide faster. We also identified areas of low heat flux, which will help stabilise the ice sheet," she told BBC News.
I knew I'd seen this somewhere before, the question is of course how significant the warming effect is, whether it is increasing or decreasing, expanding or contracting, or even on the move.
