Under these conditions, low - level cloud cover and its reflection of solar radiation increase, despite an increase in global mean surface temperature.
Second even if we ignore convection (and assume all warming of the atmosphere is from below, ie no incoming solar radiation is absorbed in the atmosphere) it is not the case that the atmosphere temperatures will «pivot» around some fixed level (increasing below it and falling above it).
What happens at the «top of atmosphere» — the level where outgoing radiation leaves for space, not itself a very easy concept — is the restoration of equilibrium, the increase in temperature that, through Helmholtz - Boltzmann at the Earth's brightness temperature 255K, restores the balance between incoming and outgoing energies.
The whole issue is that any level above what is often called the «effective radiating level» (say, at ~ 255 K on Earth) should start to cool as atmospheric CO2 increases, since the layers above this height are being shielded more strongly from upwelling radiation... except not quite, because convection distributes heating higher than this level, the stratosphere marks the point where convection gives out and there is high static stability.
As the atmospheric opacity is increased (e.g., 2xCO2), the physical location of the TAU = 1 level will rise to a higher altitude, but the outgoing flux will still come from the TAU = 1 level since radiation doesn't care about the geometric scale), and the TAU = 1 level will still correspond to the same temperature (since the solar input energy is unchanged).
Adding CO2 increases the height distribution from where radiation can escape to space, so the Earth looks colder to space at wavelengths where the effect is not already saturated at the tropopause level.
I got mixed up and made it sound as if the increase in downward radiation subtracted from the effect of decreased upward radiation, but the opposite is of course true — both effects contribute to a decrease in the net upward radiation at the tropopause level.
The imbalance is not between IR absorbed and IR emitted by a layer of atmosphere, but between the incoming shortwave solar energy from space and the outgoing longwave energy emitted to space, due to the increasing difference between the ground temperature and the temperature of the level from which re-emitted radiation can escape to space.
The downward radiation to the surface increases mainly because the low level air temperature increases, not because of the direct effect of increased CO2 in the air.
Trends as a function of CSD, Saturation: If the temperature varies monotonically over the distance from which most of the radiation reaching that level is emitted, then increasing the CSD will bring the upward and downward fluxes and intensities (at a given angle) toward the same value, reducing the net intensities and fluxes, until eventually they approach zero (or a nonzero saturation value at TOA).
The reduction in CO2 - cooling (of a layer between TOA and some other level) assumes the increased downward emission at the base of the layer from the non-CO2 absorber within the layer is greater than the decreased OLR at TOA, which is the absorption of radiation from below the layer minus the emission from the layer reaching TOA (refering to the «baseline effects» that would remain if the preexisting CO2 were removed).
The increase / decrease of net upward LW flux going from one level to a higher level equals the net cooling / heating of that layer by LW radiation — in equilibrium this must be balanaced by solar heating / cooling + convective / conductive heating / cooling, and those are related to flux variation in height in the same way.
The equilibrium response to an addition of RF at a level is an increase in net upward flux consisting of LW radiation (the Planck response, PR) plus a convective flux response CR; CR is approximately zero at and above the tropopause in the global time average.
The effect where, adding a «new» absorption band and increasing the absorption, there may initially be warming of the colder layers, etc, followed by a stage of upper level or near - TOA cooling — this includes the warming from absorption from increased radiation from the surface + troposphere — which will be greater when more of the spectrum, especially near wavelengths where the emitted spectral flux change is greatest, has a greater amount of absorption.
Increased CO2 in the stratosphere at higher levels increases upwelling radiation to space which appears to have been greater than absorption from below resulting in cooling at higher levels.
What I meant was that Planck radiation increases with body or amb ient temperature, but higher temperature, per the Boltzmann distribution, makes it more probable that rotation, vibration, and / or electronic levels will be excited, and therefore less likely to emit relaxation energy, though as you point out this may not be exactly what happens physically — emission radiation is more flat than anything with increasing temperatures.

This is also consistent with the bonchardi mechanism mode, which fairly consistently indicates we can expect a reversal of ambient air temperature increase with the next day, as the dual modality of reverse recapture recombination functions as an equalizer, and the increase in low level re radiation acts as a «heat shield» keeping more air from reaching and warming the ground, allowing ice to reformulate, while most of the temporary heat, which will largely be offset by the Atlantic shift paradigm anyway, given the lower absolute percentage of (so called?)
