How do you cope with the state of the world today? (lemmy.world)

Everything just seems so out of control. The US seems to be tearing itself apart. The world is on fire. We seem to be going backwards when it comes to freedom and human rights. We've turned our backs on each other. How do you cope with all this without just giving up?

As a result of the scientific findings and the possible severe impacts of ozone depletion, governments around the world began passing laws reducing or banning the production of CFCs and other ODSs. This culminated in the Montreal Protocol, agreed in 1987, which has now been signed by every member state of the United Nations. Signatories to the Montreal Protocol have agreed to phase out ODSs and replace them with less-damaging substances.

Since the passing of the Montreal Protocol, the emissions of ODSs have fallen to a fraction of their levels in the early 1980s and the ozone layer has begun to recover. The hole in the ozone layer over Antarctica still exists, but it has been slowly shrinking over the past two decades thanks to concerted international action.

So not completely back to how it was before we fucked it, but the problem has been fixed

"By taking a holistic look at the yearly progression of the Antarctic ozone hole over the last two decades, we find that:

The addition of recent years to the Antarctic (60°S–90°S) total column ozone time series results in insignificant long-term change since the early 2000’s, even where significant recovery has previously been reported. During this time, we find a delay in both the deep ozone hole onset date as well as the breakup date."

Tl:dr if all you're doing is looking at the peak/minimum times of year it can seem better. The hole "breathes" and they're getting delayed.

I work on diesel trucks, they create a lot of N0x. This article talks about how N0x being bad. It's a niche thing but I at least understand why I tend to see these things first.
