In particular, the authors find fault with IPCC's conclusions relating to human activities being the primary cause of recent global warming, claiming, contrary to significant evidence that they tend to ignore, that the comparatively small influences of natural changes in solar radiation are dominating the influences of the much larger effects of changes in the atmospheric greenhouse gas concentrations on the global energy balance.

You could help clairify things by answering the following question: If atmospheric layers A and B each contain greenhouse gases, under what conditions will we find that the rate of absorption by layer B of layer A's thermal emission equal the rate of absorption by layer A of layer B's emission?

We use a one - dimensional radiative - convective model for the atmospheric thermal structure to compute the change in the surface temperature of the earth for large assumed increases in the trace gas concentrations; doubling the N2O, CH4, and NH3 concentrations is found to cause additive increases in the surface temperature of 0.7 °, 0.3 °, and 0.1 ° K, respectively.
