The ozone hole boils down to two things, the lack of sunlight for six months at a time, and the stratospheric air currents preventing ozone rich air from reaching the south pole. So yeah, it might be related to changes in stratospheric circulation. Duh.
The “ozone hole” was never a hole, to start with. The whole hysteria is a huge scam in preparation of the even bigger Goebels warming scam.
If there is any remaining doubt, look up who is the guy who propped up this scam, he was called “Ozone man” by Bush Sr.
