Some greenhouse gases are pollutants, some are not. Water vapor H2O, and CO2, are not pollutants. The climate models do not take into account the affects of water vapor, since it is not understood in a way that can be mathematically described in those computer programs and there is no way currently to collect or collate the cloud cover over the whole planet. They are both requirements for life on this third rock from the sun. Human activity creates very little of either compared to what old Mother Nature puts out on a daily basis. Plants inhale CO2 and exhale oxygen, which is a requirement for our existence. You really want to cut down on your own carbon footprint? Stop breathing.
