The ozone issue was an early misuse of science for a political agenda. It was a practice run for global warming with several of the same people involved.
Attempts to ratify the Kyoto Protocol included claims that the Montreal Protocol, designed to save the ozone layer, was a success. It wasn’t, because there was no problem in the first place.
Chlorofluorocarbons then, like CO2 today, were never a problem.
Environmentalists used a natural change of ozone and CO2 to blame human activity. With ozone, the "urgent problem" was a slight decline in atmospheric levels over Antarctica; with CO2, a slight increase at Mauna Loa.
Both times, they then found and funded scientists to produce the "scientific" evidence.
I explained the problem to the Canadian Parliamentary Committee Hearing on Ozone. I didn’t want to attend, but it was a legal order. It was the fiasco I expected.
