The ozone hole and the international legislation to eliminate the indicated cause - the Montreal Accords - were a landmark. It remains true that, absent the ozone layer, life on the surface of the earth would be impossible due to too much ionizing radiation. The Pre-Cambrian explosion, where life rapidly colonized the landmasses that were hitherto barren, only occurred after the great oxygenation event, where the atmosphere of the Earth was converted from C02/methane to N/O by cyanobacteria. Before that, all life on Earth lived in the sea, where water shielded from the harsh radiation.
Unfortunately, after the Montreal Accords, this international cooperation mechanism was hijacked for globohomo "climate change" - it's really global depopulatoin.

China is ignoring the Montreal Accords and has been for years.

A globohomo depopulation conspiracy. That's a new one on me 😛.
It's astounding what folks choose to believe.

The ozone layer started recovering before the Montreal protocol could take any effect. Also uvb radiaton hardly increased during the "hole" years. Doesn't make it a bad or useless thing, but things are far more complicated than this trite oversimplification. Plus there were ready replacements that didn't inflict any other harm on the industry so it was easy to implement.

The patent on that particular CFC was expiring at that time under DuPont. By eliminating that gas, they were able to patent a new one. What replaced it was just as bad, actually worse. I think it was X30. Some countries just ignore it, because, well, Freon is no longer under patent.
I remember stories of that time, that sheep in Argentina were going blind. Kind of like "country X is heating TWICE as fast as everybody else" - it always happens in another nation, where it's much more difficult to check the veracity of the claim.
I think it was nothing more than to force existing users of Freon to move to X30 in order to profit. Our atmosphere doesn't really mix that well. Anybody that flies and goes above the inversion layer knows this.
Remember the big scare over acid rain? We had this sort of science fiction writing competition, and this kid wrote a story where the world was devastated by acid rain, and that the remaining population lived underground, and everything was precious from cardboard to glass beakers. We have been brainwashed into accepting catastrophism for at least 40 years. My damned parents thought it was ridiculous but NEVER TOLD ME, and allowed me to believe the nonsense for 30 years. They couldn't explain WHY they thought it was bunk, just that it was. Years later I finally got them to tell me they thought that certain information sources were BS, but they never told me that either, but they could come up with examples of why they thought they were nonsense.
I would have vehemently disagree with them had they told me at the time, but they would have given me a headstart on understanding our media is garbage. Now I'm ahead of them, realizing it's all garbage. I've tried a few times to introduce them to what I consider truthful information, but it's all long form format, and in order to believe it, you have to actually spend some time checking out the claims until you find out that several of the episodes are well researched and have good support, and you also have to spend time checking past claims to verify they were indeed correct. People aren't willing to listen to news programs from 10 years ago to see if they were correct.
If Rowland and Molina had made their discovery today, in the current political climate where science is often doubted and looked upon with a conspiratorial bent, would swift action have been taken? Or would the science have been politicized and the R12 lobby have been able to prevent the banning?

This ^^. If you don't follow the money it's easy to get sucked into pseudo-science..

You mean where hypothesis are tested and verified? Where discoveries are questioned, and evidence must be properly collected and provided? You may not be aware, but you are sending a pretty heavy anti-science vibe here.
Or maybe we just need to better summarize your sentence? Trust the science!

Also, you are aware Hanks is a giant pedophile right? May want to reconsider that avatar...
Cl + O3 = ClO + O2 and ClO + O = Cl + O2
This reaction results in the destruction of ozone, converting 2 O3 molecules back into 3 O2 molecules. The reaction is catalytic in Cl, meaning that the Cl radical is recycled and can react continuously with many O3 molecules in an ongoing cycle. Furthermore, they noticed that chlorofluorocarbons such as dichlorodifluoromethane (CF2Cl2, or R12 refrigerant) released Cl radical when exposed to ultraviolet light.
They realized that the most common refrigerant at the time, manufactured by the metric ton, was also capable of interfering and potentially destroying the earth's ozone layer that protects us cooking from UV radiation.
At that time, there were no special precautions taken to control R12 refrigerant use or collect and process waste gas. Old household refrigerators and industrial units were simply allowed to vent to the atmosphere when disposed of.
This was around the same time that atmospheric scientists began to notice the appearance of an "ozone hole", an apparent depletion of ozone particularly over the south pole region, that had not been previously observed.
They quickly put 2+2 together and sounded the alarm. Swift action was taken by governments around the world banning the use of chlorofluorocarbon refrigerants, and some they that Rowland and Molina may have saved the world. R12 is a "forever chemical" meaning is lasts a very long time once released. The ozone hole is still there but has been steadily shrinking since the ban: https://www.nasa.gov/missions/aura/ozone-hole-continues-shrinking-in-2022-nasa-and-noaa-scientists-say/
Rowland and Molina won the Nobel Prize in Chemistry in 1995 for their discovery.
Here is my question:
If Rowland and Molina had made their discovery today, in the current political climate where science is often doubted and looked upon with a conspiratorial bent, would swift action have been taken? Or would the science have been politicized and the R12 lobby have been able to prevent the banning?
What do folks think?
As an aside, Sherry Rowland had also been a star varsity baseball player at University of Chicago and played semi-pro before leaving sports to go save the world.
