"and just what does water vapor do in the atmosphere since there is hundreds of times the amount of it versus co2"

Depends, it can block light and reflect it back into space resulting in the opposite effect. We commonly refer to them as clouds.

"my braintrust tells me water vapor is 100 times the global warming cause than co2 is."

Well your brain trust appears to be smoking crack. Walk outside on a cloudy (high water vapor)day and say that with a straight face. May I ask who these brainy ones are?

I find your “matter of fact” answers naive and phony.
