They do tend to “thin rapidly” when they are sitting on top of an underwater volcano. Believe it or not, that lava is hot even when it comes out under the water. Ask yer college perfesser! LOL!
Due to the thermal activity in Yellowstone, a snowmobiler occasionally encounters spaces in the trail where the ground is bare and warm while all around it the snow is 10 ft deep.
Do these eggheads ever leave their ivory towers and actually experience the real world?
Dollars to donuts, while the snow and ice are melting in that one area of Antarctica due to thermal activity directly beneath it, they have been increasing on most of the rest of the continent, and the rest of the globe pretty much.
