Secondly, are there any thermal images on the heated area in the Antarctic ?
I have no information about thermal images.
The several thousand feet of ice over the surface makes for a darn good insulator.
Even in the most geothermally-active locations like Iceland and Yellowstone, heat from below has a negligible effect on climate. So as interesting as an antarctic hot spot is, I am highly skeptical of any effect on surface temps.
Thanks, I agree.
I was thinking about some possible "leakage" along the following line.
If there was an "anomaly" on Earth's crust where the magma was directly in contact with the atmosphere, there *would be* large local effects on climate, at least locally, because the magma is a virtually infinite source of large amounts of heat (also, due to the composition of the magma, I think there would be global effects from this imaginary situation.)
Then, if we made a "thought experiment" of burying the magma of this "anomaly", layer by layer, under larger amounts of crustal rock and ice and positioned at the correct point in the Antarctic continent this we'd have a more and more realistic correspondence to the actually observed situation.
Now, if the amount of rock and ice over our "anomaly" is very large, as the observations indicate, then the amount of heat and any other residual gases or material escaping to the atmosphere would be negligible or zero, *unless* there was a connection of this anomaly with some relatively thin crustal region in the neighborhood (probably under the sea, somewhere).
But, until such "shallow region" is found there could be no influence on climate, even locally.
On the other hand, the fact that the hot blob has been found exactly at the only region of Antarctica that is not systematically cooling in the recent decades, seems suspicious.
