Now how smart is that? Genius? Maybe not quite, but pretty intelligent, right? 😏
Well, I'm glad YOU think so. You seem to be forgetting about that minor 4000 miles of solid and liquid rock below all that ice. How come the core underneath the Antarctic has not started freezing? According to your theory, ice on top, freezing below. The truth is, under all that ice, 2 miles deep, there is no sunlight anyway but ten feet below that rock it starts heating up from whatever the freezing point of water is under that much pressure of 2 miles of solid ice but below that you get 50 degree F rock, right underneath that ice. In fact, homes use that effect to get close to free heating, turning 50 or 60 degree or the hotter the better, 1 mile down it is close to 180 degrees F, stick pipes in the ground and pump some heat bearing fluid, like water or oil, and it gets warm and you can use that to energize a heat pump, get something like 3 to 1 heat, say 5000 watts of energy use gives you 15,000 watts of heat.
If you were just using an electrical heater, 5000 watts of energy gets you 5000 watts of heat, not a btu more.
So that fact is pretty useful and it has NOTHING to do with the sun heating the surface. Eventually it would get cold but that eventually runs into MANY millions of years, close enough to infinity for humans.
