As you point out, the IPCC does not explicitly state that the SRES scenarios all are of equal likelihood, but, given what they do tell us (as you indicated) 1) we should not rely on the frequency distribution to develop probability of occurrence, and 2) «No judgment is offered in this report as to the preference for any of the scenarios and they are not assigned probabilities of occurrence,» it seem to me that the best we can do is to make the
simple assumption that they are equally likely (with departures
from equal probability randomly distributed).

I think this could be another reason why the derivation of the IPCC's formula for radiative forcing
from CO2 offered by Bindidon is not valid, since that derivation involves the

simple application of the Stefan - Boltzman formula, which you have pointed out is not necessarily true.
