You're just repeating the exact same fallacious nonsense that I just pointed out. Again: you don't need to have an accurate measurement of absolutely everything to have a reasonably accurate model.

Negligible, as the distance is several orders of magnitude smaller than even the difference between perihelion and aphelion (~5 million km difference between the latter vs. just ~9000 km of difference between the latter). The difference between perihelion and aphelion does have some effect though (makes Northern Hemisphere winters and summer noticeably milder and cooler respectively, and conversely Southern Hemisphere winters and summer even colder and even hotter respectively), but that's of course unrelated to exactly what you're asking. Somewhat more related is the gravitational effects of all the other bodies that cause slight changes in the parameters I mentioned previously over time, which causes the Milankovitch cycles that play a larger role over long periods of time, having various periods ranging from tens of thousands to hundreds of thousands of years long, pic related.

some americans were denying it, one thing at a time, I will come back to you later...

Orbital mechanics certainly affect climate but not in the timescale we're observing warming in. Additionally both Milankovich and solar forcings are towards cooling, not warming.
