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 oscillator has a spectrum of energy levels, separated by Planck's constant times the radiation frequency, so it follows that energy will be absorbed if this matches the oscillator frequency.
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).

It does seem at first glance that a warm troposphere would warm the stratosphere, but the explanation that more of the earth - sourced infrared radiation is absorbed lower in the the troposphere by higher levels of CO2 makes sense if one thinks about the thermodynamic losses involved in the CO2 re-radiation processes; some of the earth - sourced infrared is transformed into kinetic energy and only a fraction is reradiated as more infrared radiation (if I'm understanding correctly).

Yet on these sites (and in the media, and even by a few semi related scientists who kinda keep an eye on the issue or are semi involved) treat it as if it is some sort of both immediate, and linear, contemporaneous correlation between increased lower level atmospheric re radiation, and increased (or changed) global ambient air temperatures, which is absurd, and belies any real deep understanding of the actual issue.

If you bothered to read my book, you would see that I am saying that there is already enough CO2 in the atmosphere to absorb all the IR radiation that it can absorb, i.e., increasing the level of CO2 will have little effect.
The only way CO2 could absorb any more IR than it is already absorbing is if 1) the surface started re-emitting more IR, which could only happen if more sunlight reached the surface, or 2) atmospheric water vapor levels dropped, freeing up more IR to be absorbed by CO2, in which case, warming would not occur, because that radiation was already being absorbed by the water vapor that disappeared.
