For a poster who is sure this is all about science -- you seem overly zealous to discuss the socio-economic-political aspects of the AGWarming campaign.. That's what it's REALLY about --- is it not?
That's why there is a campaign to confuse pollution with AGWarming and confuse carbon with carbon dioxide.. Not very rigid is it? But it works for people who can't or won't LEARN anything about the science debate.. Fact is -- folks are being "confused" on purpose..
Is something that exists in your lungs at concentrations 3 to 5 times greater than in clean air --- a pollutant??
Is it the word "pollutant" that has you confused? How about if we change that to " too much shit in the atmosphere to sustain life on Earth."
Would that work better for you?
That's a bit too scientific and specific for me..

And it's deceptive to enroll the public in that campaign of misinformation to make the "ends justify the means"..
What description would meet with your approval and satisfy the conditions of your exacting standards of specificity?
What I'd like is ALMOST what you would like -- I'll wagerr.
I'd like to drop this farce of blaming 0.5deg of Global Warming for EVERY environmental issue that we face. Seriously, the warmers have stretched this meme so thin, no one is buying...
And I'd like to go after REAL CARBON POLLUTION, just like we used to without all the lying and deception. I'd like to clean up the miles wide garbage pits in the ocean and work for conservation.
But this AGW farce just SUCKS THE AIR out of every other enviro issue...
