And the current Supercomputer Climate Models....have no knowledge of clouds.....
Messed up title. Negative cooling would mean positive heating.
If the Earth gets warmer, then ocean evaporation increases, producing more clouds. Condensation of water vapor into rain releases heat into the upper atmosphere, where it is more easily radiated away into space.
As oceans get even warmer, they are more able to sustain hurricanes, which are POWERFUL mechanisms for transferring heat energy from ocean surfaces to the upper atmosphere.
If anything, global warming would have been beneficial. Warmer times equal more evaporation, more rain, and longer growing seasons for crops. Global cooling means shorter growing seasons, less rain (drought), and famine.
