Take a look at this paper: http://www.met.hu/idojaras/IDOJARAS_vol111_No1_01.pdf There are energy considerations that lock the planetary average flux optical depth to a value of 1.841. Add as much CO2 as you want, the system will not reach a tipping point. The only thing that can change this is a change in the amount of insolation entering the top of the atmosphere or the amount of heat coming up out of the ground. --Mike Jr. []

Finally, someone understands what Miskolszi is saying. Thanks for the post, Mike Jr. You made my day.
