Like a lot of climate sized issues, the ozone hole was a rate based issue, In that our rate of “hole growing” was the real problem that needed addressing immediately. And the rates have MASSIVELY improved thanks to the global CFC actions.

Current direction of rate change show that we reach zero depletion (rate of 0.0 ozone loss) by late 203x, with zero hole in late 20xx (rate of -x.x as it heals).

That’s a very considerable turnaround for damage we did over the course of 30 years.
