“Whatever happened with the ozone layer panic, if scientists are so smart?”
We listened to the scientists, and the problem went away.
Didn’t go away, just stopped getting worse at an alarming rate.
It’s the same as people using the example of the Y2K bug being a non event. Yeah, because globally trillions of dollars were spent fixing it before it became an event.
thanks for the tldr
No
Get that marble brain Reddit-style bs outta here. If you wanna deny, you’re gonna have to come up with a reason that you could be right. Otherwise, we’re just gonna point al laugh at your dumbassery.

Did you even bother to read it?
Among other things it says: “Based on the Montreal Protocol and the decrease of anthropogenic ozone-depleting substances, scientists currently predict that the global ozone layer will reach its normal state again by around 2050.”
The reason it isn’t discussed as much is because it’s on the mend and the only things newsworthy are the larger than normal cyclical hole that forms. Another thing mentioned was a volcanic eruption in 2022 that is believed to contribute to that “larger than normal” hole.
Nothing there disputes the fact that we took action. I worked as a refrigeration tech and we even had to learn about this before we could be EPA certified to handle refrigerants.
Yes. Thank you, cheese stick.
When you do things right, people won’t be sure you’ve done anything at all.
I wonder how many people will see this and not know its a quote from Futurama
I literally had this exact exchange with someone last year, when they tried to cast doubt on global warming by comparing it to the ozone. Another person did the same , using acid rain, and I pointed out that the northeast sued the shit out of the Midwest until they cut that shit with the coal fire power plants.
The Conservative Party led Canadian Government and the Regan-era Republican US Government started working on the US-Canada Air Quality Agreement, which was signed by the George H.W. Bush administration into law in the US (and the Brian Mulroney led Government of Canada).
That’s right — two Conservative governments identified a problem, listened to their scientists, and enacted a solution to acid rain. And now the problem has virtually disappeared.
Oh how low Conservatives have fallen on both sides of the border since those days.
Imagine if we did this with climate change. Imagine if we tried to switch to renewable energy en masse 20 years ago.
like as if we wanted to live
Tell me you don’t live in NZ without telling me you don’t live in NZ
There were goddamn Nickelodeon phone-a-thons where you pledged to not use cfc products. This shit was serious.
Edit: I just remembered ,they talked about how bad the sun was for kids in Australia, or something.
Australia and New Zealand do not fuck about with sun safety. Even with the improvements in the ozone layer, our skin cancer rates are still way higher than the rest of the world
I’d argue that while we are much more diligent than other countries, and regulations are much stronger. The average person doesn’t pay nearly enough attention, and the fact the UV index isn’t required to be mentioned on weather reports, or as prominently or more prominently than the temperature, is a big oversight in my opinion.
I check the UV every time I go outside (other than when it’s died down over winter), just as you’d check the temperature, and I think it’s wild barely anyone else does.
New Zealand do not fuck about with sun safety.
Except we were kicking the can with sun screen regulation until 2022.

Until this law, sun screen lotion didn’t have to prove that they actually provided the SPF that they claimed.
The sun is still awful here, the ozone hole is still a thing.
But thanks world, at least I can go out for a solid 4.5 months of the year without worrying about the sun at all, and 6 of only needing to be somewhat careful. Not too shabby :)
Just to be clear, are we sure that the ozone holes are still shrinking?
Looks like it had been expected to heal by 2040, but might also be affected by by climate change - reminder that even when we fix climate change, CO2 stays in the atmosphere over a century. We can only stop making things worse, but it’s your great grand children who stand to really benefit
I was thinking of this paper from 2018:
ACP - Evidence for a continuous decline in lower stratospheric ozone offsetting ozone layer recovery
Abstract. Ozone forms in the Earth’s atmosphere from the photodissociation of molecular oxygen, primarily in the tropical stratosphere. It is then transported to the extratropics by the Brewer–Dobson circulation (BDC), forming a protective ozone layer around the globe. Human emissions of halogen-containing ozone-depleting substances (hODSs) led to a decline in stratospheric ozone until they were banned by the Montreal Protocol, and since 1998 ozone in the upper stratosphere is rising again, likely the recovery from halogen-induced losses. Total column measurements of ozone between the Earth’s surface and the top of the atmosphere indicate that the ozone layer has stopped declining across the globe, but no clear increase has been observed at latitudes between 60° S and 60° N outside the polar regions (60–90°). Here we report evidence from multiple satellite measurements that ozone in the lower stratosphere between 60° S and 60° N has indeed continued to decline since 1998. We find that, even though upper stratospheric ozone is recovering, the continuing downward trend in the lower stratosphere prevails, resulting in a downward trend in stratospheric column ozone between 60° S and 60° N. We find that total column ozone between 60° S and 60° N appears not to have decreased only because of increases in tropospheric column ozone that compensate for the stratospheric decreases. The reasons for the continued reduction of lower stratospheric ozone are not clear; models do not reproduce these trends, and thus the causes now urgently need to be established.
and this paper from 2023:
Potential drivers of the recent large Antarctic ozone holes | Nature Communications
The past three years (2020–2022) have witnessed the re-emergence of large, long-lived ozone holes over Antarctica. Understanding ozone variability remains of high importance due to the major role Antarctic stratospheric ozone plays in climate variability across the Southern Hemisphere. Climate change has already incited new sources of ozone depletion, and the atmospheric abundance of several chlorofluorocarbons has recently been on the rise. In this work, we take a comprehensive look at the monthly and daily ozone changes at different altitudes and latitudes within the Antarctic ozone hole. Following indications of early-spring recovery, the October middle stratosphere is dominated by continued, significant ozone reduction since 2004, amounting to 26% loss in the core of the ozone hole. We link the declines in mid-spring Antarctic ozone to dynamical changes in mesospheric descent within the polar vortex, highlighting the importance of continued monitoring of the state of the ozone layer.
As far as im aware the hole in the ozone layer is basically gone
Remember when cavemen unga bunga’d about dinosaurs? Whatever happened to those dinosaurs! It’s like the Flintstones wasn’t actually the ground breaking documentary it was or something!
Like he even read the response
Woow it’s impressive how you all follow the narrative. Here is your bone. Good doggie. My god
You don’t think that listening to subject matter experts is a wise way to determine truth? By all means, enlighten us with a more consistent strategy.
Dunning Kruger
Matt Walsh, Nazi moron and overall creep, fuck that guy.
TBH “The whole world agreed on something” narrative doesn’t really reflect what happened.
Actually, The Industry dropped using CFC after a cheaper and luckily safer alternative has been discovered right around that time.
There was a necessary round of nearly all governments on Earth agreeing to fine and extinguish business or even throwing executives on jail if they insisted on using the more expensive alternative.
Only after that people stopped using CFCs.
Honestly, some times I wonder if we live in an episode of Captain Planet. Some people look like plain childish cartoon villains.
Okay why the fuck has this been top of my front page for two days
Because Lemmy is still 1/100th the size of Reddit.
Lack of new content on lemmy. Go post.
Lemmy auto sorts by “active” so my responding to you will now keep it at the top of your page for day 3 lol
Wtf was that dumbest posting about? He never learned about CFCs in 8th grade high school? Embarrassing
I’ve always hated this comparison because the two problems are just not the same, at all. CFCs were nowhere near as ubiquitous as fossil hydrocarbons, and CFCs had an essentially drop-in replacement, which fossil fuels do not. There’s no non-hydrocarbon fuel that we can just replace for coal, natural gas, gasoline, diesel fuel, jet fuel, etc. None that I’m aware of, anyway.
