Yes.
But as Eric said "there's the notion the the lapse rate between
the surface and the tropopause will remain the same, mol." (What
does "mol." mean?)
However, that does not answer your objections. It is yet
another "constant".
What everyone is missing is that the model being used is wrong.
It is not the radiation which changes. It is the albedo!
Increasing the CO2 concentration results in raising the altitude and
latitude of the snow line. This is one reason why the Arctic sea ice
(low altitude) is melting.
No more clues :-)
