Global Warming

Subject: Greenhouse effect

I have read your book (The Skeptical Environmentalist) with great interest. I have one question:

According to Tony Scott at,

"Water vapour is the most important greenhouse gas: it absorbs about five times more terrestrial radiation than all the other gases combined." (p.4)

If this is so, can you be sure about the relatively small effect of that part of carbon dioxide which is due to human activity?
