Not to diminish your point, which I completely agree with, but the current discussion about climate change is not related to the ozone layer, but is primarily about greenhouse gasses and associated global warming. The former was down to pervasive use of CFCs, which have now mostly been regulated away; the latter is down to (in particular) carbon emissions.
