Did we sign our cosmic death certificates when we put a hole in the ozone layer? (page 2)

bohm

sab, i wouldnt worry about it, the substances which cause the depletion is largely being phased out, and the ozone layer will rebound.

A lot of what caused the ozone hole is speculative theory. What is going on that high in the atmosphere cannot even be duplicated in lab to be put to the test. Clorine was suppose to be the main culprit in cloroflorocarbons, especially refrigerant 12 and 11, but when Mt. St. Helens blew, it put more clorine into the upper atmosphere than all of the refrigerants ever produced (since the early 1930's). This topic could be debated and probably will be for a long time.
