It's special because there is no convective or latent heat transport at all within it and so
radiative fluxes through the tropopause must exactly match the TOA flux after the troposphere has adjusted to the instantaneous forcing.

Something specific has to happen in order to change a photon's frequency, and that isn't a big player in
radiative fluxes through the Earth's climate system.
Not exact matches
But the troposphere can still warm with an increased
radiative cooling term because it is also balanced by heating
through latent heat release, subsidence, solar absorption, increased IR
flux from the surface, etc..
A comparison of CO2 and CH4
fluxes from eutrophic reservoirs suggests that eutrophication does little to change the net carbon balance of reservoirs, but greatly increases the atmospheric
radiative forcing caused by these systems
through the stimulation of CH4 production (figure 3).
But in a given model you can often find ways of altering the model's climate sensitivity
through the sub-grid convection and cloud schemes that affect cloud feedback, but you have to tread carefully because the cloud simulation exerts a powerful control on the atmospheric circulation, top - of - atmosphere (TOA) and surface
radiative flux patterns, the tropical precipitation distribution, etc..
This is achieved
through the study of three independent records, the net heat
flux into the oceans over 5 decades, the sea - level change rate based on tide gauge records over the 20th century, and the sea - surface temperature variations... We find that the total
radiative forcing associated with solar cycles variations is about 5 to 7 times larger than just those associated with the TSI variations, thus implying the necessary existence of an amplification mechanism, although without pointing to which one.
I went
through that link in that statement and don't see anywhere Shaviv agreeing that Cook et al. correctly classified his abstract of his paper «On climate response to changes in the cosmic ray
flux and
radiative budget».
For example, Chase et al. (2000a) found that regional land - use change can cause significant climate effects in other regions
through teleconnections, even with a near - zero change in global averaged
radiative flux.
In other words, the reduced
radiative energy
flux must be compensated
through increased temperatures or altered latent / sensible heat
fluxes.
