CO2 is a trace gas comprising 0.039% of the atmosphere
As of April 2010[update], carbon dioxide in the Earth's atmosphere is at a concentration of 391 ppm by volume.[1]
http://en.wikipedia.org/wiki/Carbon_dioxide
Mans contribution to that is estimated to be around 3.5% of that...
Total CO2 put out by humans every year:
27 gigatonnes.
Total CO2 put out by all other sources every year:
220 gigatonnes -- Consumption of vegetation by animals & microbes
220 gigatonnes -- Respiration by vegetation
332 gigatonnes -- The oceans
772 gigatonnes -- TOTAL from all other sources.
27/772 = 3.5%
What happens if we GAS IT UP? How about 1000x current?
In human subjects exposed to low concentrations (less than 4 percent) of carbon dioxide for up to 30 minutes, dilation of cerebral blood vessels, increased pulmonary ventilation, and increased oxygen delivery to the tissues were observed (Gibbs et al. 1943, Patterson et al. 1955). These data suggest that carbon dioxide exposure can aid in counteracting effects (i.e., impaired brain function) of exposure to an oxygen-deficient atmosphere

Whats happening to most of the CO2?
Oceans Absorbed Missing CO2
"The ocean has removed 48 percent of the CO2 we have released to the atmosphere from burning fossil fuels and cement manufacturing," Sabine said after reviewing data gathered between 1989 and 1998 from three major studies of the Atlantic, Pacific and Indian oceans. The studies collected more than 72,000 ocean samples.

Why does CO2 rise?
CO2 rises always follow the warming up of the earth
Why is it rising?
Because the Earth is starved for it. Nature is correcting itself.. Man's contribution is only helping..
Co2 is the magic gas that makes plants grow

Now if you were someone who wanted less life (humans) on Earth you would sell them on this myth that they are killing themselves by producing what naturally exudes from them in an attemt to cut back on carbon emissions in turn kill off the food which feeds them. Along with other means such as vaccines/eugenics, geneticly modifying their food, etc
