So it snows, and Eli digs into the drafts pile to dig this one out.
Eli understands that the old guy is trying to trash him. Eli would be quite happy to talk it over with him, if the old guy wanted to have a discussion, but he appears to want to talk to others without others talking to him and the Rabett is not interested in that. OTOH, we have been hopping about the net and came across the figures from Mark Jacobson's books on Atmosphereic Modeling (link since disappeared) and came across this interesting figure. Looking at it we see that the difference in absorbed incoming solar energy is about a factor of two higher at the equator than at the poles (100% difference) but the emitted outgoing IR radiation above the atmosphere is only about 25% higher at the equator than at the poles.
As near as the team at Rabett Run can make out the large units on the ordinate are 100 W/m^2, which agrees with these measurements of average solar insolation.
What first caught Eli's eye was the implication that radiation and convection move enthalpy from the tropics to the poles. No surprise there. It's called weather. This, of course, is averaged over the year, different cloud conditions and more.
So the bottom line is that even though the temperature difference between the poles and the equator is ~ 50 K, the solar insolation at the surface is a factor of two higher at the equator and the same is true of the emission from the surface as predicted by the Stefan-Boltzmann relation, the amount of energy emitted by the earth in the polar region is only about 25% less than at the equator.
