Now, here's the interesting thing IMO... (besides how convenient this all was to certain corporate entities)... The reason this 'ozone hole' had never been seen previously was because we'd not had instrumentation in space capable of detecting it previously. So, we have no idea if this was a normal cycle (I recall there being correlation to sunspot cycles) or if this was something that was actually abnormal. The fact that it seems to be self-repairing during a time of historic low sunspot activity is interesting.
And now the whackoes are claiming that mankind saved the planet from the ozone hole, thus we must do the same with AGW*. Just listened to some idiot “scientist” spout this on John Bachelor’s show.
(* or is that AGC ?)
