CO2 concentrations seem to be increasing at 4 ppm, at least according to recent measurements:

Some, of course, doubt that significant global warming will be an issue, but regardless of that, what happens if CO2 levels rise above 2,000 ppm:

Quote:What are safe levels of CO and CO2 in rooms?
250-350ppm: Normal background concentration in outdoor ambient air
350-1,000ppm: Concentrations typical of occupied indoor spaces with good air exchange
1,000-2,000ppm: Complaints of drowsiness and poor air.
2,000-5,000 ppm: Headaches, sleepiness and stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate and slight nausea may also be present.
5,000 ppm: Workplace exposure limit (as 8-hour TWA) in most jurisdictions.
>40,000 ppm: Exposure may lead to serious oxygen deprivation resulting in permanent brain damage, coma, even death.
