Ted, now you're getting confused between outdoor vs. indoor concentrations of CO2. The levels of CO2 which are considered to cause considerable "global warming" are in the range of 400 ppm, or 0.04%. THAT'S what's being called a "pollutant." You're confusing that with CO2 levels in poorly ventilated indoor areas such as a crowded auditorium or train. Tenchusatsu

Currently, CO2 is a trace gas. Do you really want to see it get up to even 1%? Even if we could increase CO2 100 ppm every 10 years (instead of the actual 100 years) that would take another 1,000 years to get to 1%. Not really a big issue - since everyone knows with peak oil etc we'll run out in a decade or two and coal in 500. :-) 1% is 10,000 ppm so dividing by 100 ppm yields 100 time periods of ten years is 100 * 10 = 1,000 years - minus a couple decades for the current 300+ppm. Using the current rate of 1 ppm per year it would take 10,000 - 380 = 9,620 years to get to 1%.
