It's not a pollutant, it's a greenhouse gas

It's a HIGHLY FRINGE greenhouse gas that only absorbs a miniscule portion of the light spectrum, meaning its effect tops out quickly and has huge diminishing returns.

You simply have no idea of what you are talking about. The whole global warming scam is based on a 'TIPPING POINT' where CO2 causing a little rise in temp creates more water vapor, which is an ACTUAL major greenhouse gas.

Co2 contributes up to 26% of the total greenhouse effect despite having a concentration of only 400 ppm in the atmosphere. It's concentration is so small there's plenty of returns left for it to give. It will easily increase the temp of the earth's surface a few degrees over the coming years which is a major problem. Every degree melts the ice caps a little more which releases even more CO2 plus methane which is an even worse greenhouse gas in addition to a whole other host of issues.

You are correct that water vapor accounts for the majority of the greenhouse effect, but the balance is delicate enough that atmospheric carbon can easily tip the scales toward disaster. Not in 20 years or whatever the fearmongering shitlibs are saying, but it'll be a problem eventually. And as I said, this will all happen eventually anyway, but we can stop accelerating it. We need to buy time for our descendents to figure out a more permanent solution.
