PD, I’m a bit confused. Are you saying that we cannot add CO2 to the atmosphere without first removing water vapor? Why not?
Regarding ozone: Fertilizer makes the world go round, but it doesn’t mean you should eat it. Just because it has a beneficial function does not mean it’s useful everywhere. Just because it’s not useful in one situation doesn’t mean it lacks value in every situation.
Accepting that ozone is a harmful pollutant does not require you to join the global warming cult. Same goes for the water vapor and CO2 percentages.
