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).
Dr Zalasiewicz said: «Like any geological boundary, it is not a perfect marker — levels of global radiation really rose in the early 1950s, as salvoes of bomb tests took place.
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.

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.
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.
