Now that is a silly statement. What is being discussed is the rapid increase in GHGs. Without any GHGs, there would be glaciers at sea level at the equator.However, too fast of an increase in GHGs, and the climate changes too fast for the biosphere to adjust. And that equals periods of extinction.CO2 is a greenhouse gas and thus a harmful addition to our atmosphere. A "pollutant" is "any substance, as certain chemicals or waste products, that renders the air, soil, water, or other natural resource harmful or unsuitable for a specific purpose".
CO2 above 280 ppm fits that description. Excess CO2 is a pollutant.
CO2 is a greenhouse gas and thus a harmful addition to our atmosphere.
Yup, because an atmosphere without greenhouse gasses would be better........DERP!
