Remember my "Things I Know #'s 3 & 4, and things we don't know" post?
I just ran across one of Richard Lindzen's papers from 1994:
What we know and what we don't know about global warming.
Granted, it's a 13 year old paper. Wonder how much we didn't know then that we still don't know now -- and how much we know now that we didn't then? I'll have to read it.
I've heard it said that if we knew then what we know now, there would never have been a Kyoto.
