The hole and the ozone layer, and climate change are two different issues. The UN and World leaders made an agreement in the late 80s to stop industries using the harmful chemicals that were damaging the ozone and leading to more people getting cancer.

After 30 years of not using them, we've started to see the hole repair itself, and in another 40 years it could be back to normal. So, if current governments were to come together and take action on climate change we could see a positive difference. But yeah, because of how big a deal the whole "climate" is, some of thowe changes will be irreversible. Once ice caps melt, they're not coming back, until there's another ice age!

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.

The ozone layer protects us from UV radiation (and thus skin cancer, etc), its basically sunscreen for Earth. The changing climate is caused by 'greenhouse gassess' (such as carbon dioxide, methane) filling the upper atmosphere. Like how an oveecast cloudy night in winter will be warmer than a clear sky, the gasses trap the heat on the surface, and that builds up over time.
