“The eruption of the Hunga Tonga volcano in January 2022 injected a lot of water vapour into the stratosphere which only reached the south polar regions after the end of the 2022 ozone hole.
“The water vapour could have led to the heightened formation of polar stratospheric clouds, where chlorofluorocarbons (CFCs) can react and accelerate ozone depletion. The presence of water vapour may also contribute to the cooling of the Antarctic stratosphere, further enhancing the formation of these polar stratospheric clouds and resulting in a more robust polar vortex.”
Sounds like more of a natural expansion of the human created phenomenon, hopefully temporary

Personally I suspect someone is cheating on their emissions, or using something that's a bit cheaper but is ozone damaging in some process.

The only reason I can think of is to avoid diplomatic problems. When scientific reporting doesn’t make sense it is either due to ignorance or politics, and I doubt the ESA has an issue with ignorance.

This will make skin cancers slightly more prevalent in southern latitudes but I can’t see any other changes that aren’t marginal. It isn’t great but we are not “fucked” by any means.

#10It is not just human-made, but of late, and unfortunately, our earth hasn't been very kind to itself.
