The Ozone layer is healing
A new paper in Nature says that the decreased use of chloroflurocarbons (CFCs) has helped to shrink the Ozone hole.
This also will affect the jet stream which has been shifting towards the South Pole because of the depletion of ozone. The jet stream has a major role in weather patterns.
There is a jet stream tug of war between ozone levels and carbon dioxide levels. We still need to reduce the amount of CO2 which tends to pull the jet stream to the south.
