hanrahan,
A pollutant is a waste material that pollutes air, water or soil, and is the cause of pollution.

Three factors determine the severity of a pollutant: its chemical nature, its concentration and its persistence


so by definition anything can potentially be a pollutant.

"CO2 isn't a pollutant." just saying something over and over again doens't make it fact.

What source told you that CO2 isn't a pollutant?
What about other GHG are they not pollutants?

What evidence and what source would it have to come from to acknowledge AGW is real and CO2 is a contributing factor?

If this source provided the evidence you require, and you acknowledge AGW what action/s would you support the governments doing?
