The ozone hole seems under control, after 20 years of regulation

The ozone hole peaks in September. While it was not the largest it has been it remains above average. The linked article discusses the science behind the destruction of this protective layer of earth’s upper atmosphere. Scientists don’t expect the hole to significantly shrink for about another decade because of the long lifetimes (40-100 years) of CFCs already in the atmosphere. Full recovery is expected by about 2070 (if we don’t release another wave of pollutants that destroy the upper atmosphere).
