A new study out this week (
via smalldeadanimals) questions the old CFC (chlorofluorocarbons) being the causeof ozone depletion. Now it seems that maybe it has more to do with the 11 year solar cycle and the cosmic rays reacting with chlorine in polar clouds.
The fact is, as with so many other things in the Earth sciences, we are still learning, and this just proves once again that scientific testing and proof must trump scientific selling of theory.
