Skip to comments.The Ozone Hole is Shrinking: The CFC ban Has Nothing to do with the closing of the ozone hole

On October 24, AT published the article Ozone Hole Shrinking, NASA Announces. The author, Howard J. Warner, correctly wrote that there are many factors that cause the Earth’s ozone layer to grow or shrink, and that chlorofluorocarbons (CFC’s) are merely one factor of many. Mr. Warner cited volcanoes as one of these factors, for example. He provided a link to an article, which stated that although the Antarctic ozone hole is now shrinking overall, it actually grew in 2016, owing to the recent one-time eruption of the Chilean volcano Mount Calbuco. This eruption injected sulphur into the atmosphere, which formed the compound sulfuric acid (H2SO4) -- which ate away at the ozone layer.

One of the commenters to Mr. Howard’s article was kind enough to include the entire chemical reaction by which every CFC molecule is alleged to eat away at some 100,000 ozone molecules, in a catalytic chemical reaction, before the CFC molecules themselves are “washed out of the upper atmosphere.” This reaction was discovered by F. Sherwood Rowland and Mario Molina, for which discovery they won the Nobel Prize in Chemistry for 1995, and it led to the ban on CFC’s. One wonders why it wasn’t the Nobel Peace Prize instead.
According to the news reports, now that CFC’s have been banned, the Antarctic ozone hole is on track to heal itself by 2050. The reduction of the Antarctic ozone hole is being touted as a vindication of the theory that banning CFC’s was needed to accomplish this. Environmental activists across the world have seized upon the news of the closing of the ozone hole as proof that the world was right to ban CFC’s during the 1980s.

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.
CFC ban was a huge scam. Patents were running out on old refrigerants so manufacturers created new ones with new patents in order to maintain their huge profit margins.
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?
The next thing you know... Acid rain will be back on the social media map... I don’t recall ever getting high off that stuff.
...AND, NASA wanted a budget increase...that would include “studying” the “CFC-created” ozone hole...
You didnt read the article, did you?
That hole has been there since wild poodles roamed the earth. It takes sunlight to produce ozone and areas that get little to no sunlight for a period of time have less ozone. The cfc hypothesis is/was a scam. Possibly a test case for the whole climate change scam. Tyrants never rest.
I wish I could find it now. I once read an article that penguins were found to have evolved to deal with high levels of UV radiation, which implies Antarctic ozone holes have been a thing for 1000s of years.
ABSOLUTELY. The automotive industry was the worst of fraud. They actually spread the lie that older systems could not also use the newer freon. Absolute outright criminal fraud, they do just fine loaded with 134. Billions of dollars were made because folks bought new cars they didn’t need or retrofitted older systems they didn’t need to retrofit because of this scam.
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? Its like trying to float a concrete block in your bathtub.
Thanks for adding that.
This scam is right up there with Y2K.
Uh, not sure what world you live on, but CFC’s were around LONG before 1957-58....
Secondly, the atmosphere isn’t segregated by atomic weight, if it were, you’d see a haze near the ground of the heavier gases.
You really need to read up a bit on things, your arguments are ones of ignorance.
Yup. CFCs breakdown in sunlight and the lighter chemicals were floating upward.
I remember my dad talking about it when it happened. There wasn’t much of a fuss about it because the experimental evidence was so clear and replicable (unlike AGW).
A friend once told me about something in the eye of penguins or some creature in the Antarctic. In essence the creatures had an eye behavior or structure that was a defense against ultraviolet rays (the value of the ozone layer is that it absorbs ultraviolet rays).
He said this behavior was something that would have evolved over thousands of years, proving that the ozone hole phenomenon has been around for thousands of years.
Evidence is absolutely clear on this, this isn’t some debate.
They believed, (incorrectly) that CFC’s would not break down... however, evidence showed that they did indeed break down from sunlight in the upper atmosphere.
This isn’t some conspiracy theory, or fudged hockey stick data, this is proven and repeated and observed science, there is no debate that CFC’s caused OZONE depletion.
Anyone arguing otherwise is just wholesale ignorant.
The ozone hole is a cheap graphic fraud. All they did was designate some low value of Dobson units the color black and presto, it looks like a hole. It would be like if USA Today replaced the color purple with black on their winter weather maps. It would look like there was a black death sweeping across Minnesota and the Dakotas. A hole is physically impossible due to Fick’s law of diffusion. Rather, there is a lower concentration of ozone over a pole during the winter (surprise, because ozone is made by the sun), but on the opposite pole, there is a higher concentration. 6 months later, those stats reverse.
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.
