The difference between Apoapsis and Periapsis is 5 million km - just under 1.8 times the diameter of the sun. Based on the to-scale illustration above, do you really think that this will result in all of the stuff you are suggesting occuring because of the "offset" distance mentioned above? And, over a distance of 107 versus 108 sun-diameters? (Or, something close to that.)
Answering your in-bold-text question: No, I don't. Just like I said in the post you're quoting. Um, what's going here? I wrote this is one of two (actually three) reasons why the lower southern hemisphere latitudes are cooler than their northern corresponding counterparts. That's what this discussion is all about.
Is your current post reply the first of a multi-post reply, or are you blatantly strawmaning this? If it's the former, you didn't mention that's what you're doing.
You wrote, "The video in post #630 has such strong Flat Earth 'proof' in it that nothing else really compares to it or can stand up against it." and "It is irrefutable that - if the Ball Earth model were true - the climate would in fact be identical-or-very-similar in each of these comparisons. There are no two ways about it."
I took what you said very seriously. Is he right? Can it be reasonably refuted?
My post's 'Part 2' layouts: in-your-house experimentation demonstrates soil heats much more than water. In this one specific
video, with soil and water under heatlamp, over 20 mins the soil heated to 2.8 times the temperature of the water. The northern hemisphere has 2.4 times the land area that the southern hemisphere does. (Land Mass: Northern 78%, Southern 32%.)
Do you really think this will have no measurable effect on the temperatures and climate between the corresponding 45-90 degree latitude hemispheres? If you don't, I really have to doubt your sincerity, cause I don't doubt your capacity.
My honest opinion is one doesn't need to add to this very significant 'soil heating' and 'total land mass' differences portion. But we also have that while the earth is 5 million km farther away from the sun, aprx 3% more than the avg, the southern hemisphere is in its winter tilt-away season. The total amount of extra heat to northern hemisphere is not zero. But you can erase this part if you want as I agree it's surely much less significant than the soil-heat/land mass differences reason.
Adding a third thing that is 'not zero', we've seen that Antartica is cooler than the Arctic due to much higher elevation (the highest avg elevation of all continents), mostly a 1-to-3-miles-thick layer of ice on top and the most arid continent. Antarctica is: summer 50*F/winter 36*F cooler than the Arctic. The Artic accumulates more heat than Antartica and that's less heat to distribute around the southern hemisphere. Again, surely not as much as the soil-heat/land mass differences reason.
The conclusion is very simple. There are significant and testable reasons why the temperature and climate are cooler at the 45-90 latitudes. You wouldn't want to stand on that for irrefutable proof of FE.
