If we eventually look back and wonder why we got into all this carbon mess, the villain has to be NASA (n). N had the best atmospheric physics in the whole, probably the only. They did all sorts of great things right until about 1980.
Then n went all pansy, and decided that philosophising was real neat. This article shows what they consider 'proof' of correlation. The ozone hole went down, and chlorine went down as well. They cite a huge number of chemistry equations that never have done under those conditions. Well, they actually have been done, but that's buried in obscure papers, and I have no intention of exposing them to the sun.
They only measure hydrochloric acid and they assume a whole chain before that. I am amazed.
