So it’s not CO2, it’s H2O?

From what I've read CO2 isn't even a green house gas. If it goes up it lags behind temp increases. Increased water vapor on the other hand has a vastly greater effect on temp increases and can be considered a green house gas. If I'm off on this I stand to be corrected.
Suffice it to say that when the earth decides to "do something" ain't nothun we can do about it.

H2O in the form of water vapor accounts for something like 95% of the Greenhouse gas effect. And 99% of water vapor is from natural causes. The Greenhouse effect of CO2 is about 0.25%.
