You must share an amazing ability with these scientists.

You can find data where there is none. IIRC it was the late 80s before they had good ways to measure statospheric ozone (good enough to see the south polar 'hole' anyhow).

Actually, I recall a National Geographic story (perhaps the cover?) in 1957, for the International Geophysical Year, that discussed the increasing size of the Antarctic ozone hole.

Back then, we had no envirowackos and it got no hysterical press attention.
