At present, the effect of CO2 is or is close to saturated at the tropopause (small or zero net flux at the tropopause), and because parts of the lower stratosphere are nearly isothermal while the upper stratosphere has a negative lapse rate, the effect CO2 at TOA is saturated in a sense (OLR reaches a minimum, beyond which, farther increases in optical thickness result in increasing OLR).
