With hot gasses and lava escaping through fissures in the earths crust, over millions of years, what is the outcome?
The earths MANTLE (the hot, molten part under the CRUST) will cool and shrink. The crust then is (somewhere) suspended over a void and when the void gets large enough, the crust COLLAPSES in what we recall as earthquake. As the crust gets thicker what happens? The earthquakes get less frequent but more powerful.
So the mantle is cooling while we have created pollution that traps heat. By the way, if we would have retained our horses over furthering our technology with the internal combustion engine, we would have created about 20 times the amount of greenhouse gasses (with the same labor output involved)
