  • The ozone layer/"hole" is caused by fluct?

    CFC's are very heavy, they stay close to the ground and do not affect the stratosphere. That is a little bit strange...Volcano's put out approx 10X more times chlorine than man produces. Ozone Center of WA states: "The 1991 volcanic eruption of Mount Pinatubo led to temporary severe ozone depletion but recent observations have shown that ozone concentrations have returned to pre-Pinatubo levels." The change in the ozone layer is related to seasonal changes. (Cambridge University Professor Dr. Glenn Carver)I think this was a very good example!
