Ahh, c'mon - seriously? Seriously? You really don't know that climate scientists have been taking water vapour into account from the outset?
This is the heart of the problem: you seem to seriously believe that you're asking real, probing questions - but you're not. Not really. If you were really asking from an honest position, you would have looked to see if your question (or in this case naked assertion) actually had a basis.
it doesn't. Water vapour has been known as a greenhouse gas for as long as CO2 has.
