"Interestingly, recent studies have shown that the size of the ozone hole affects the global temperature. Closing the ozone hole actually speeds up the melting of the polar ice caps, according to a 2009 study from Scientific Committee on Antarctic Research. "
So if we want to save the ice caps, we need to bring back ozone-depleting chemicals

Ah, but then we'd have more skin cancer

Anyway, I'm confused because the previous paragraph says the weather is affecting the North Pole ozone layer and the size of the holes vary from year to year.
