There will be less cloud cover over the oceans and thus more radiation to warm the earth, but at the same time, more water vapor in the air to trap heat? How do you get more humidity and less clouds? Why do they expect less cloud cover over the oceans with a warmer earth? (I’m not challenging anybody’s authoritay, just trying to understand the system. No, not the LGF system, the sun/earth, radiation, absorption system.)

And why does having the distribution of CO2 over more than just the troposphere magnify the greenhouse effect? I have no doubt that it does, just trying to picture the mechanism.

He needs to match the level of his explanations to the level of his audience. Dummies like me actually try to follow what he’s saying and find a lot of information missing. Grrr… pisses me off, now I must google. :-P
