Lapdog;

The poster I was replying to was talking about the 'pollution' over the city that one could SEE

Now as much as you like to classify CO2 as a 'pollutant', in this particular case it wouldn't matter how much CO2 was in the air over the city you still couldn't 'see' it.

The 'pollution' he was talking about was particulate pollution (soot etc)that you can see; smog!

Perhaps you should have read his post before you replied to mine.

I would suggest to you that if you want to stretch the point a call CO2 a 'pollutant' it would have to exist in such quantity that it hampered breathing, since no one is suggesting it will ever get to that point, so CO2 in our atmosphere is nothing more than a green house gas!

Sure, if you use the term loosly enough, anything can be called a 'pollutant' but your really stretching the point to call CO2 a pollutant in present or predicted quantities!
