Derek, thanks for the reminder. I did need to reread that thread. Ferdinand's comment confirms ALL energy absorbed by CO2 is redistributed.

This means CO2 does NOT re-radiate any energy received from a higher termperature source, it will radiate at it's local environment temperature as a cooling function but I don't see how this can provide any "forcing" to the much warmer surface.

This will slightly simplify my question to: "How much heat energy is transfered to the 3 tons plus of air by the contained mass of 1,860.86 grams of CO2 that can only "see" 8% of the total upwelling radiation? I must assume there will be a steady rise in temperature over time, but what timescale/temperature riserate are we looking at?

Have you seen the latest Guest post by Willis Eschenbach over at WUWT?

I see there is a comment by Monckton of Brenchley (15:30:32) :

In my struggles to understand the GHE I was fooling with "layers", hoping I could find an "Ah-Haaa!!" moment. My 1 meter layer of CO2 at 2,500 meters produced such big numbers that my confusion rate went logarithmic so I reduced my layer (shell ?) to 2 millimeters of CO2 at 5 meters.

Your comment answered my question about how much absorbed energy will go to heating the air. Answer: all of it! And how much is re-radiated. Answer: Non of it!

Progress, of sorts.
