The ozone layer is self-repairing. CFCs were causing the ozone layer to deplete. Banning them has allowed that healing to happen.
The CFC ban was a good example of straightforward, science-based environmental science. Experiments were done, experiments were replicated in other locations to verify the original research.
A solution was proposed and adopted. No problem. No ‘belief’ involved.
Read the article. CFCs are 4x heavier than the atmosphere. How to they rise? Why was the ozone hole observed in 1957-58 before CFCs?
You didn’t read the article, did you?
Exactly this headline is BS..
You can’t say “CFC’s are one of MANY factors”, but the claim Banning CFC’s had nothing to do with it...
There is NO doubt CFC’s reached the upper atmospheres, and were broken down by sunlight, the chlorine molecules would then steal an O from the O3, creating ClO... which would then lose its O to another stray O molecule, creating Cl again and O2 and the CL would then steal an O from another O3 molecule and the process would continue to repeat...
CFCs were bad, are bad, and the worldwide ban has been a good thing... sadly some countries still manufacture them, but the vast reduction in their production and release into the atmosphere is a good thing.
Everything about the CFC ban was fraud. The author raises the very obvious question, how does a molecule 4x the weight of the primary atmospheric components rise into the stratosphere? It’s like trying to float a concrete block in your bathtub.
During the same time period women used less perfume... so I’m going with that as the reason... it’s just as likely.
I suspect this is one more example of the earth being a self correcting closed system. And some day we’ll understand the cycles and not fear them.
For now this is one more liberal ‘the world is ending scare story’ that just bit the dust.
the ozone hole is like a chimney, allowing atmosphiric pollutants to excape into space..... it opens during large pollution cycles and closes during weak cycles..
