A total lack of physics education appears to be a prerequisite among the pro-AGW demagogues. Thanks Explorer89 for that excellent comment and the ping.

My old friend, PV = nRT begs to differ, and tells me that the temperature was higher when the pressure was higher.
Catastrophism ping?
LOL, it's as if they can't help themselves.
After all, there's gold in them thar hills of climate change. Something to consider is how much this new Gold Rush will cost us taxpayers.
In this particular case, the ideal gas law doesn’t hold, and rocks can indeed melt on decompression due to changes in the chemical potential of stable phases becoming unstable with subsequent dissolution back into the melt. That said, the theory this scientist is pushing is preposterous on the face of it, due to energy budget considerations, and known tectonic mechanisms.
Due to thermal expansion most materials become less dense with increasing temperature. That aside, I have often wondered if quakes or vocanic eruptions could be,in part, caused or facilitated by land tides.
