Carbon Dioxide: Pollutant? At a high enough concentration, any chemical can be considered a pollutant We are increasing the concentration of CO2 in our atmosphere The troposphere is warming and there is evidence that the additional CO2 is contributing to the warming.

Sulfur Oxides What do sulfur oxides become once they are released into the atmosphere? What effects can it have on the environment? What do you think is the trend for this polluted has been over the last 20 years?
