I don't know that's it's comparable. The ozone required manufacturing changes, it didn't require an upheaval on how we live. Sure, it's "don't emit the bad gas", but the gases come from different sources.
The primary difference was that the ozone depletion didn't gain much traction as a political wedge and world leaders were able to take the threat seriously. 14 years after scientists published basic research warning of potential risk, the Montreal Protocol was signed. 25 years later there was a 98% reduction in release of ozone depleting substances and the ozone layer has begun to heal. Throughout all of that, DuPont…
Things like CFCs were taken seriously. Things like radiation were taken seriously (for better or worse, yielding our insane regulatory landscape around building new nuclear power plants).
The last major thing that scientists warned about that was really taken seriously (in the sense that something was done about it before it had/would have had massive negative effects) was world overpopulation, with the publication of things like "The Population Bomb" and China's one-child policy, etc.
Unfortunately, that one was gotten wrong; we now know that without any intervention, world population will tend to moderate itself and we won't actually see mass starvation due purely to too many people. I think that error was the first major blow resulting in people no longer really trusting catastrophic predictions.
I wonder what the world would be like if instead climate change was put forth as a catastrophic issue with the same fervor back then.
