Just to be clear, are we sure that the ozone holes are still shrinking?
As far as im aware the hole in the ozone layer is basically gone
Actually there are signs it's been growing again. Because we forget history so quick.
Sorry I left my ozone vacuum running overnight.
I never realised how much MegaMaid reminds me of Unreal Tournament.
I see articles up to 2022 talking about it shrinking, healing on the predicted timeframe. 2023 is a huge outlier, possibly caused by a volcano, but there’s variability every year. That doesn’t mean it’s growing again
I need to look into it again, but they had found favtories in china emiting a ton of it.
Really? Damn, didn't know that
The ozone hole size is influenced by the strength of the polar vortex, the Antarctic temperature, and other things in addition to the concentration of CFC molecules. It's barely shrunk, but CFCs are so long-lived that was expected - the critical point is it stopped growing over 20 years ago. I believe they expect to start seeing shrinking within the next decade.

Looks like it had been expected to heal by 2040, but might also be affected by by climate change - reminder that even when we fix climate change, CO2 stays in the atmosphere over a century. We can only stop making things worse, but it’s your great grand children who stand to really benefit
I was thinking of this paper from 2018:
and this paper from 2023:
Unfortunately there can still be emissions:
