The question you are asking is why does it get colder as you go higher, is just a property of gases, as the pressure decreases it gets colder.
not even close. the sun's apparently providing heat, not gas. why would less gas mean less heat?! you are insisting the opposite is the case for behavior at the poles.
Firstly, you need to know that JRS is one of the more irrational flat earthers here, and he has invented a lot of flat earth "data" and "facts" that he's simply made up on an ad hoc basis.
completely false. educate yourself before you make such patenttly bs claims. dual earth theory is well defined, and there is no ad hoc behavior whatsoever, everything is explained by well-defined and simple rules which are themselves logical deductions. you cannot just lie about a theory and act like you've made a point.
you'll agree that it is warmer at the equator and colder at the poles. Surely if the earth was heated from inside the heating would be even...?
educate yourself on the interior of a dual earth. there is less space between the center of the earth and the equator, than between the sun and the poles.
The sun quite clearly heats the planet as demonstrated by a day with clouds in the sky. When the sun goes behind a cloud, you will feel noticeably cooler as you will receive less radiant heat. When it comes back out you feel warmer.
really, so a scattering of water molecules is single-handedly capable of noticably reducing heat that's travelled millions of miles?
clouds are just reflections of behavior at the core of the earth.
amazing how you resort to fictional air and still can't come up with an answer.
