It makes huge leaps in the assumption that it actually knows the concentration of CO2 in our atmoshere. Distribution of CO2 varies greatly from the upper atmospheres down and mixes differently as well.
CO2's radiative forcing is logarithmic.It's because of rising CO2 and other atmospheric gasses rising that our stratosphere is cooling.
Having a role in the greenhouse effect is not the only thing that CO2 does. Not all effects of green gasses are the greenhouse gass efffect.
Its not rererred to as the greenhouse effect but rather a parallel effect.
