[Crutzen's] Nobel for ozone likely should be withdrawn because there was never any proof that CFCs were affecting the ozone. Variations were due primarily to variations in ultraviolet radiation combined with natural atmospheric circulation. I don't think Crutzen ever said that. CFCs were the equivalent of human produced CO2 because you always have to blame humans for every change and evil. Besides, Crutzen was also the one who suggested, in another ill-informed attempt at geo-engineering, that we must add sulfates to the atmosphere to offset global warming.
Of course, the causes and effects of CFCs in the atmosphere has been well established, and not by any stupid scientists either. Here is Oderus Urungus, describing how he and the other interstellar chaos warriors known collectively as GWAR were released from their icy Antarctic Prison:
Because of the brief dominance of hair-metal bands in the late 80’s, and their overuse of hair spray, a huge hole was burned into the ozone above the GWAR temple, and the member’s of GWAR began to de-thaw.
