Climate changes, but the unusually stable climate Earth has had for the past 10K years allowed our species to rise. Now we are destabalising the system.
The system has been destabilized many times already. It will adapt.
BTW no ine with half a brain can conclude that huge masses of biological carbon could have been burried under a thick strata layer over million of years.
Umm, what? Are you saying coal and oil are conspiracies that dont exist? Are you saying God put it there to be used? I'm not sure which idea you are hinting at, and which to refute.
No, I'm saying that something major happened which destroyed the ancient civilizations and burred whole ecological systems into the ground in an extremely short period of time.
