    I thought the hole is naturally occurring, but that CFCs were causing it to grow more than the normal seasonal variation.

      It’s ‘naturally’ occurring in that (simplistically) air currents in the upper atmosphere tend to concentrate ozone depleting compounds produced in the northern hemisphere (more or less) in the southern.

      CFC’s are not the only ozone depleting compounds.
