I wonder what your threshold is for a specific gas to have an effect on the climate. If .04% is not enough, how much would it take? You seem to know all about it, so please explain this.
Compared with water vapour, i.e. clouds, CO2 pales into insignificance as a greenhouse gas.
"water vapor, which contributes 36–70%"

Note how shaky the data is: 36–70%, 9–26%, etc.
