A seminal moment came 1984 when three papers were published by Christopher Essex on thermal radiative transfer and thermodynamic equilibrium. This year, 2014, Essex joined the GWPF advistory council.
Given the ongoing heated discussions on the Talkshop on broadly this subject, perhaps this adds light. Fat chance!
Here is one of the papers (another can be found, third is paywalled)
Minimum entropy production in the steady state and radiative transfer
AA(Department of the Environment, Canadian Climate Centre, Ontario)
Astrophysical Journal, Part 1 (ISSN 0004-637X), vol. 285, Oct. 1, 1984, p. 279-293. (ApJ Homepage) 10/1984
An extremum principle is developed for radiative transfer in a gray atmosphere by using a purely thermal example from Planck’s (1913) work on heat radiation. Entropy is accounted for, as is Prigogine’s (1947, 1967) theorem describing equilibrium as a thermodynamic state of minimal entropy.
