Your link is not relevant to the point made. Just to be clear water vapor capacity increases due to temperature, for example, relative humidity measures how much water vapor is in the air for a given temperature. Any sort of increase in temperature will increase water vapor. Yes, CO2 raises the temperature, you get a massive increase in water vapor, which again, is a more potent ghg. Reversing that same amount of CO2 does not magically reverse all of that water vapor. This is the crux of the problem, why water vapor is now also a problem that needs to be addressed.
