The UN treaty to protect the ozone layer has prevented a likely surge in skin cancer in Australia, New Zealand and northern Europe, a study published on Tuesday said.
If the 1987 Montreal Protocol had never been signed, the ozone hole over Antarctica would have grown in size by 40 percent by 2013, it said.
Ultra-violet levels in Australia and New Zealand, which currently have the highest mortality rates from skin cancer, could have risen by between eight and 12 percent.
In northern Europe, depletion of the ozone layer over the Arctic could have boosted ultra-violet levels in Scandinavia and Britain by more than 14 percent, it said.

The authors purport to claim that they could [show] how the ozone layer WOULD have continued to deplete if CFCs hadn't been banned.
How do you know how accurate, or otherwise, their claims are?
This is like me showing you a graph of the amount of money I personally would have made if I had never joined the Army.
No, it's more like me showing you a graph of the amount of money I probably would have made if I'd stayed at my last job. I was on a certain wage, I had certain expenses, and I could project from those.
But hey, if you think you know better than Professor of Atmospheric Chemistry Martyn Chipperfield, why don't you call him up and tell him how stupid he is?

Sadly, I bet he gets his fair share of these kind of calls.
