Ok, so you argument boils down to, “ You’re wrong but I am not going to bother refuting what you say”? Lol.
There is sixty times as much water vapor as carbon dioxide and water vapor has three times the heat capacity. It is also massively more available to affect climate. Raise the temperature and you readily get a lot more of it. CO2 not so much.
It is also worth noting that trapping heat and raising temperature are not the same thing. It gets a lot hotter in dryer areas because there is nowhere for the energy to go. The simplistic CO2 arguments being made by global warming advocates are compounded errors in support of a doomsday fantasy.

Because of its short average time in the atmosphere, a molecule water vapor has a Greenhouse Warming Potential (GWP) of -0.001 to +0.005, (where CO2 is 1.0 by definition).
[G]reenhouse-gas warming [by watervapor] is outweighed by increases in reflectance from humidity-induced low cloud cover, leading to a near-zero or small cooling effect.Yet your analysis appears to give equal weight to a molecule of natural water vapor and anthropogenic CO2.
