High CO2 levels, as it turns out, make us dumb. Those in urban areas (where higher CO2 levels are typical) and those spending a lot of time indoors get it the worst. At 1,000ppm, human cognitive ability drops by 21%. We're on track to have 1,000ppm globally, by 2100. Indoor air often exceeds 2,000ppm. Check it out.

One thing this study did not address is how far down this road we already are, since we've gone from 280 to 410ppm. There's ample evidence to me that the change in cognitive abilities from a century ago has already been quite negative. Idiocracy is *fantastic*, btw.
