Even the EPA says that shortly afterwards, the amount of chlorine in the atmosphere increased by 10%, (of the short term variety, it dissipates within a year). Keep in mind that 99.9978% of all chlorine in the atmosphere is naturally occurring. It is the Chlorine component of CFC's that they say are destroying the ozone layer. We were told that just a 1% increase in CFC's would have catastrophic consequences, which is why we had to act, yet here was an eruption, that increase chlorine by TEN PERCENT? Why did the world not end? |
You wrote that Mt Pinatubo
"spewed Billions on tons of CFC's into the Atmosphere"
That is complete and utter nonsense.
Very large volcanic eruptions may throw sulfate aerosols and HCL into the upper atmosphere - where in the presence on man-made CFCs, they will increase ozone depletion.
Volcanoes do not emit CFCs to the ozone layer.

The researchers from NASA, San Jose State University and the University of Colorado predict the hole will appear if volcanic activity coincides with cold Arctic winters, during a time when there are still high levels of ozone-depleting CFCs in the atmosphere....
While reduction in the use of CFCs has been successful, ozone recovery is not guaranteed because it can be jeopardised by volcanic eruption.
"We can predict with confidence that there will be enough CFCs around for the next 30 years that a major eruption will enhance ozone depletion," Dr Fraser said.
