Is it more likely to get a sunburn under the ozone hole in the South Pole?

Maybe, but who’s going to lay out in a bikini just to find out?

I guess it depends on what IT you’re laying out to burn!!! :0

All other factors being equal, yes.

When the seasonal ozone hole extended over Australia in the 1990’s, there was an increase in sun exposure related medical conditions.

In New Zealand, because of the lack of Ozone, there is a nasty skin burn rate as well as a disease that kills sheep. You can look it up.
