How do we know that it was the Vienna convention that fixed the hole in the Ozone layer? Maybe it just repaired itself? I think there are getting on for 200 countries in the world so who knows how many of them actually bothered applying agreement? How can you tell what China and other totalitarian states did? In any case, changing the power source for spray cans was never going to cost much anyway. Not like the $trillions for more renewables.
A bit like Coral reefs seem to have at least partly done their own repairs? Article from the Times, August 4th 2022:
"Live coral has recovered across large parts of Australia’s Great Barrier Reef, according to researchers.
Two thirds of the reef showed the largest amount of coral coverage in 36 years, but the conservation area remains vulnerable to increasingly frequent “mass bleaching”, a long-term monitoring programme by the Australian Institute of Marine Science (AIMS) reported."

Compare this to George Monbiot in the Guardian, 26th June, 1999, the underlining is my emphasis:
"
Nothing can save the world's coral unless we begin,
immediately, to keep our environmental promises and consume far less fossil fuel. And one of the things this means is that, if we truly value coral reefs, we must stop travelling around the world to see them, for long-haul flights are rapidly becoming one of the major sources of global warming."
"The
imminent total destruction of the world's coral reefs is not a scare story but a
fact" says George Monbiot.

Very helpfully, the Guardian has a function where it flags the article as being 23 years old. Which is very useful in this case as it exposes how ridiculous the prophecy was.
