When I said "if anything, it's the opposite," I was just referring to the specific shading pattern in one particular figure on the NASA webpage. I really don't think either northern or southern latitudes receive more or less sunshine than the other.
Thanks for your answer. I will wait for a few days and see other answers before I comment. I do request that all hold on to your "rational" for a day or so before you print/justify it here. I am just curious that what one things "obvious" is also "obvious" to others. Thanks again.
I may have posted here but one book you may like to read (if you have not seen it already) is Muller (yes the "Physics for the future presidents" fame) book "Energy for future presidents". His site also has the largest (virtually every important data or link to that data) data if you like to play with your own model.
