Nelson: How do we know these feedbacks exist?

Denning: We know there must be negative feedbacks because Earth has almost always had liquid water throughout geologic time (oceans never froze solid or boiled away).


Very good.

We know there must be positive feedbacks because climate has changed in the past even with very small changes to the radiation balance.

Whoa. There's a logic problem there. You can't assume the only affects on climate are GHG's.

------------------------------

Denning: In my opinion many of the problems of rapid global warming are probably avoidable if we adopt ambitious measures to develop non-carbon energy before China, India, and Africa emerge as major energy users in coming decades.

What is he talking about? China is already THE major energy user. Doesn't he know that?
