Earth’s atmosphere allows the sun’s heat in but resists its re-radiation back into space. The atmosphere is comprised of nitrogen 78%, oxygen 21%, argon 0.93% and CO2 0.04%. Many other gases are present in trace amounts. The lower atmosphere also contains varying amounts of water vapour, up to 4% by volume.

Here's a graph of the CO2 concentration in the Earth's atmosphere since 1960:
MacSwain's point is that water vapor is a greenhouse gas, and the amount of water vapor in the atmosphere totally dwarfs the amount of CO2 - so even if the amount of CO2 was to double, triple, or quadruple, it would seem to have very little effect on the total amount of greenhouse gas in the atmosphere.
Originally posted by KazetNagorra Is the report in the OP relevant for any of the points that I was making?
My only point is that you have conceeded to the global warming rhetoric. Have you read the report that investigates those who have convinced you of your stance?
