Apr 17, 2017 at 13:41 comment added user7733 Spencer - the image you posted is a partial extract from a Trenberth radiative flux diagram. Not sure where you got it like that or whether you have modified it yourself but it has had removed the very important figures for radiative flux (measured in W/m^2) apart from the one of 340 for incoming solar. This bastardisation of a diagram is abhorrent because it is likely to mislead and confuse. Can you get the correct full version posted instead please and make clear that radiative flux figures and directions are NOT heat transfer or energy transfer quantities/directions figures/directions .

Apr 15, 2017 at 19:10 comment added jamesqf @bmende: No, I'm saying that if you do the experiment in a vacuum, and make the ball out of a good thermal insulator, you will eliminate the effects of convection & conduction, and so see just the radiation effects. As for your claim that Earth doesn't curve, sorry, but I've been high enough to see it for myself.
Apr 15, 2017 at 14:42 comment added bmende @jamesqf Are you saying I will see the appropriate results with a vaccuum chamber? Unfortunately many answers to questions like these involve the invisible space vacuum, that's how they dodge questions like these. But they still won't be able to deal with the reality that the earth doesn't curve.
Apr 14, 2017 at 18:24 comment added jamesqf @bmende: If you placed the ball in a vacuum, so that it wasn't warmed by convection, and made it of an insulating material, it would be obvious. Why not try it? Or just compare common things - say a lawn chair with the back laid flat, vs with the back tilted perpendicular to the sun.

Apr 14, 2017 at 8:20 comment added user2821 @bmende Depends on the size of the ball and its internal energy budget. The heat we are talking about in this context is transferred by radiation and everything is well explained in the answer and follows the most basic geometric rules.

Gah; another typo
Apr 11, 2017 at 20:10 comment added bmende So does this mean that if I were to place a ball outside in the sun, that the equator line would be significantly warmer than the polar regions? Surely this would never happen.
