Refering to bands where optical thickness is constant over the interval of each band, if the atmospheric LW absorption is limited to some band (that doesn't cover all LW radiation), than increases in OLR in response to surface warming will occur outside that band, so OLR will drop within the band — there will still be some portion of stratospheric or near - TOA cooling that will be transient, but some will remain at full equilibrium.

The answer, Izen, is of course that when Obama held his «5 to 10 years global warming acceleration» speech, he had not the faintest idea that 5 years is a totally irrelevant interval when talking about decades long climate trends; and he doesn't have the faintest idea about that because he wouldn't know a physical unit if it crawled up his nose and died there.A trend over 5 years is not much better than noise, and detecting an ACCELERATION with such a noisy trend is entirely impossible.
