The sooner we completely phase out CFCs and other stratospheric ozone depleting gases, the sooner we can go back to the good old days where you could enjoy that sunshine.
The prediction is 2050-2070 we will be back to the 1980 level of ozone thickness.
Scientists have been trying to combat the perception that it is to blame for the high prevalence of skin cancer in Australia for a couple of decades now - it will never be a good idea to 'enjoy that sunshine' the way people used to.
(2001 paper - https://pdfs.semanticscholar.org/6944/503469e4f779e99884e144...
" Sufferers of skin cancer today should more likely blame their affliction on skin type and sun exposure during their youth than any changes in ozone distributions over the last twenty years. Therefore it is safe to say that even without ozone
depletion, Australia would still have a very high rate of skin cancer.")
Can't agree more. It was pretty crazy in the 70s/80s.
You had people literally baking themselves in the sun with tanning oils. Even after "Slip Slop Slap" was first promoted in the early 80s everyone was still trying to get a tan.
Over Antarctica, yes. But in some conditions (right winds? I forget) thinner patches of ozone do blow over the south coast of Australia, and does increase UV exposure.
"It's so lovely and sunny here, why aren't you tan?"
"Because the sun is a terrifying ray of pain and death here."
