Is that photon radiation in all directions the only thing you disagree with SSDD and Bob?Gladly. This is an easy one:
Can photons travel from cooler matter toward warmer matter?
Are they repelled somehow? Is emission prevented?
Of course they can, but what happens after that is a highly controversial topic amongst serious scientists that work in spectro analysis. And that is: what exactly is the molar extinction coefficient for CO2 at the R,Q and P branch:

Dr.Heinz Hug investigated this and concluded:
We integrated from a value E = 3 (above which absorption deems negligible, related to the way through the whole troposphere) until the ends (E = 0) of the R- and P-branch. So the edges are fully considered. They start at 14.00 µm for the P-branch and at 15.80 µm for the R-branch, going down to the base line E=0. IPCC starts with 13.7 and 16 µm [13]
The radiative forcing for doubling can be calculated by using this figure. If we allocate an absorption of 32 W/m2 [14] over 180º steradiant to the total integral (area) of the n3 band as observed from satellite measurements (Hanel et al., 1971) and applied to a standard atmosphere, and take an increment of 0.17%, the absorption is 0.054 W/m2 - and not 4.3 W/m2.
This is roughly 80 times less than IPCC's radiative forcing.
Can photons travel from cooler matter toward warmer matter?
Of course they can
Excellent!
SSDD and Bob are sad.
Thanks.
If it is, it`s as pointless feuding over it as this "barrier"

Because the bulk of the heat transfer in the lower altitudes happens by convection.
A BIC lighter flame also radiates heat in all directions but a bulb thermometer held a few inches beside it will barely register the heat, but could bust quickly if you hold it above the flame.
The StB equation clearly does not account for the bulk of the heat transfer from below to above, so why use it?
You could apply it if you were pointing an IR thermometer at the lighter measuring the heat radiation it would register pretty well the same from all angles...but now you did not have to heat the glass and the liquid you had to heat when you used a bulb thermometer, and actually transfered heat .
Then again if you would do this with a bulb thermometer on the ISS in a zero g environment it would not matter if the thermometer is above or beside the lighter.
But it would not take long for the flame to get snuffed out due to the lack of oxygen because convection needs gravity.
Anyway on earth we do have it and once the bulk of the heat is near the stratosphere it matters little what effect the CO2 had at the lower altitudes.
There you encounter a layer which has been warmed to 270K by UV absorption.
That is a stable inversion layer, meaning there is no more vertical mixing & convection.
The only way out is to radiate through it and at this point the StB equation does apply and fully accounts for the energy transfer.
So the CO2 is not the elephant in the room, it`s the sun and the (high energy) UV + the ozone concentration. That`s the radiation which is powerful enough to peel your skin like it happens to a boiled potato. It wasn`t the CO2 back radiation that cooked it if you did not use a sun screen.
Is that photon radiation in all directions the only thing you disagree with SSDD and Bob?
No. I just think that's one of their larger physics errors.
It leads them to invent "smart photons" and "covailent (sic) bonds" that create fields that deflect cooler photons.
Because the bulk of the heat transfer in the lower altitudes happens by convection.
Awesome.

Who uses it to "account for the bulk of the heat transfer from below to above"?
