Excellent summary. Not to invalidate any of the points you have made (all great and precise observations by the way), I do believe that climate change is man-made. This article explains it from an insider view: https://dothemath.ucsd.edu/2021/12/my-brainwashing/
However, as you have pointed out, it doesn't matter if it's man-made or not: elites are giving the worst possible response to problem: more growth. Maybe, if we had stopped polluting in the 1970's it would be less of a problem... As they say though, that ship is now gone.
