Didn't they figure out a while ago that the ozone hole was being caused by solar wind?

There was some research in the 00s about solar winds depleting the ozone layer. But that was a separate thing from the human/CFC caused ozone issues. Solar winds can deplete the upper levels of the ozone, but the main part of the ozone layer are the lower levels (making up 80%+ of it), which are the ones damaged by us, and aren't affected by solar winds.

The solar winds research was interesting for explaining why some measurements didn't match predictions, but they weren't particularly related to the harmful effects of ozone damage.
