According to this report in the BBC, the ozone layer is getting better. Well, sort of:
1) It's not being fucked over as much as it used to be.
2) The upper ozone layer will therefore probably be back to normal within 50 years, assuming we don't do more damage to it.
3) No idea what's going to happen to the lower atmosphere. We just don't know yet.
Marvelous.
