CFCs are responsible for the ozone hole. There are no known significant natural sources of CFCs. The ozone hole was caused by humans and its course correction was due to the political will to phase out CFCs.

> Climate scientists can raise the alarm or whatever but have no credibility

Climate scientists have credibility.

There is a class of problems where "when things get really bad" is also the point when it's too late to implement a solution. Driving off a cliff, for example.

What would you do if you studied this matter for several years, and found overwhelming evidence that this is such a category of problem?

> Ozone hole? Not sure how much of that was cyclical vs in human control.

If you don't know, maybe you should look it up instead of touting your ignorance in a public discussion forum? Your ignorance is not noteworthy. And while you're at it, you can educate yourself on climate change and proposed solutions to it, too. You seem to be suffering from several significant misconceptions, likely because you're bought into a narrative spun out by political hacks with zero understanding of the relevant scientific principles/knowledge and a vested interest in never changing that.

> not when the proposed solution is some kind of global authoritarian communism

Please make an effort to engage more substantially with reality, especially on this forum.

> Things like this, it’s still hypothetical. Climate scientists can raise the alarm or whatever but have no credibility, certainly not when the proposed solution is some kind of global authoritarian communism, and it always is.

Absolutely ridiculous. Climate scientists have credibility; climate science denying cranks who blather about communism have none.

> When things get really bad

Things are really bad.

Muted via my HN front end ... I won't be responding further.
