CO2 isn't the only thing given off by burning fossil fuels. And "pollutant" is like "weed" - plants that are native to an area can still be weeds when introduced to the wrong place, or when they appear in excessive numbers. Even water can be a pollutant in some contexts. |
Not in the sense most global warming/climate change discussions mention it. It's the same when media outlets use refrigeration towers expelling water vapour (another pollutant by your definition) to show the "pollution", because CO2 is transparent and they can't alarm people with it.
