• Al Gore did a great film on Global warming. Part of the film at the end explains how the world reacted to the holes in the ozone layer and the holes are now repairing.... Unfortuantely it will not be so easy to fix global warming but it was given as an example of what we can do if we all work together. So they can be fixed.
  • The truth of the matter is that there is not nor have there ever been any holes in the ozone layer. What people call an ozone hole is actually a thinning of the ozone layer that occurs over the poles in the winter. Ozone is both created and destroyed by ultraviolet radiation from the Sun. During the winter there is no sunlight in the polar regions. Therefore, there is no new ozone created. When the sunlight returns in the spring, then the ozone levels return to normal. It does not take 50 years. It just takes a few weeks.
  • Where I live is the skin cancer capital of the world, this is due to harmful U.V. radiation caused by thinning of the Ozone layer. The Ultra Violet Index today is 14(Extreme) we have the same in winter, the U.V still gets through. The Ozone layer can repair itself. but only if we stop releasing Ozone depleting chemicals in to the atmosphere.
  • 1-8-2017 I studied atmospheric chemistry in uni. It is a terrifically complicated process, but for the most part it is chloro-fluro compunds that break up ozone. Of course the ozone can regenerate, the same way it was generated the first time.
