Is the 2nd law of thermodynamics generally valid? Looking at the temperature distribution in the atmosphere, I always had difficulties to explain how this goes together with that law. As always, if something is difficult, you have to do it on your own. When I investigated further, the surprising outcome for me was, that the 2nd law of thermodynamics is not that generally true as it is used.
Since I cannot find anyone in my surroundings who can point out a
mistake in my thinking, I wrote a blog article about the contradiction to the second law of thermodynamics found at:

This goes into the detail of where the issue is. So, if you find some spare time, I would very much welcome if you proof me wrong.
