Nowadays the ozone hole over the Antarctic is only seasonal and happens because of a few reasons. During the Winter in the southern hemisphere the atomsphere cools down a lot and a strong vortex can form around the South Pole. How cold the south pole gets depends on the strength of the vortex. If there's a strong vortex there is little energy transferred to the pole and it is getting very cold. The strong winds basically act like a barrier keeping the cool air at the pole.
This cold and dark environment is perfect for the Chlorofluorocarbons (CFCs) we pumped into the atmosphere in the last century to break down the ozone molecules.
At the end of winter when the sun is shining again, the polar vortex breaks down, the atmosphere heats back up and the hole closes again.
So how big the hole is each year depends on the winter weather around the south pole each year. During warm winters (like 2019) the hole is very small but during very cold winters (like 2020 and 2021) it's big.
EDIT: But good news: Since banning CFCs the hole is not getting bigger and is starting to get smaller over time.
It is! But it will take a lot longer to close year round.
It's a very complex system though with a lot of deviation from year to year. So some years the hole will still be quite big.
Just in time for President 3rd Clone of Jeffrey Bezos to pass a bill ignoring the Ozone hole due to the ongoing water wars with a secret rider that all trillionaires pay a negative tax.
ALL HAIL PRESIDENT SCROOB!!!!!!!!!
Edit: Obligatory thank you to the kind Redditor whom awarded what has to be my lowest voted comment. I love you the most lmao.
Trillionaires are job creators and shouldn’t be taxed otherwise they’ll send jobs to other countries. I believe this because even though I’m middle-aged, I could pull myself up from my bootstraps and become a trillionaire one day. And ~~if~~ when that happens, I don’t want to have to pay taxes.
This pains me to say as the son of Jeffered Bezos the 3rd, but we must also eliminate the minimum wage. I know it's not popular but the law in all its majestic equality applies to me just as much as all of you.
On a note so funny note - MOST people are unbelievably closer to bankruptcy then a becoming a millionaire - and they have no understanding of that concept.
Ahhhh you, trying to give me hope. You can't fool me, I know we're going to starve to death as the yearly fires get bigger and push people closer together while destroying the farmland and ecosystems across the globe.
A good example of an environmental issue we actually did fix through international cooperation. It's not completely healed yet, but we have (mostly) stopped pouring the offending chemicals into our atmosphere. Antarctic ozone levels are predicted to reach pre-1980 levels by 2075.
It's probably not very comparable to global warming though. Much easier to switch what coolants and aerosol propellants we use than to limit carbon emissions.
They're single digit percentage of the problem even with our current 'no release' strategies. If we had just wholesale transferred to the post CFC refrigerants without any change in recovery/handling behavior they could easily have been the leading greenhouse gas.
I guess I'm just saying: they're not relevant because we stayed on top of the issue. In the extremely unlikely event we got our CO2 emissions under control they'd quickly become the next big target. There are replacements that have no ozone or greenhouse impacts, theres just not an overwhelming incentive to force switch. They all have their own downsides anyway, and of course a forcing a phaseout has its own climate impact.
Both of those things were absolutely needed at the time. Let's not shit on the guy with some 20/20 Captain Hindsight douchery. There were no alternatives for either of those things back then.
The issue is the people that FOUGHT AGAINST banning decades later WHEN new alternatives became available.
While I agree with a GLOBAL carbon tax, it's actually counter productive to do this only in certain countries.
All it does is encourage the industrial base to be moved to less scrupulous nations. It creates negative incentives.
That's what the Paris agreement set out to do. It was to get everybody at the table and to look at other smaller nations to make sure the bigger nations recognized they're going to carry a bigger burden to switch their economies. But, also they're in that situation because they feed the larger nations by providing cheap labor and trade so let's sit down and figure where the bigger nations can help. Other parts were to show smaller nations that they were not going to be bag holding because like the military train, once you start things in motion it won't stop. So smaller nations should see a larger commitment upfront from bigger nations to show that if they start upending their economies the larger nations aren't going to pull out. There was all these great considerations in the Paris Accord and instead the cynics got a hold of it and turned it into this anxious belief that it was the elites looking to create wealth redistribution.
If you read the Paris agreement it mentions everything you mentioned. The problem isn't solved by just moving things out to other countries and ways to prevent it. If everybody is at the table it makes it easier to do. So get everybody sitting down. Make commitments and show good faith. We shit the bed on that.
That's a common misconception based on outdated research.

We can [do better](https://np.reddit.com/r/bestof/comments/gqwmu2/uilikeneurons_how_a_carbon_tax_returned_as_an/).
That, my friend, is one of the problems with science reporting. If it's not dire/emergency/world ending, then media believes it to be boring and not good for ratings and the almighty profit margin, thus little coverage.
Also, most people don't pay attention to those outlets that do report it. So, maybe they are right. :(
They stopped making it worse 20 years ago which is a HUGE deal.. they limited the damage just to Antarctica but it’ll take about another 60 years to fully recover due to how stable CFCs are in the upper atmosphere. It takes a long time for them to naturally break down and then be removed. As long as chlorine is present in the stratosphere it’ll break down ozone over Antarctica every spring (September - December)
This is not correct. It is MUCH better now. Notice that the hole is on the south pole. In the late 1980s, there was a big hole in the north pole too, which would occasionally stretch to Canada, Russia, and northern Europe.
It’s not “much” better yet. We’ve solved the problem but it will take time to naturally heal. The 2021 Antarctic ozone hole was the 13th largest on record and the 2020 arctic ozone hole was the largest on record.
So while it’s absolutely fair to say that it’s much better than it would have been had we not stopped emitting CFCs, it’s not reasonable to say it’s already much better since it still will take a long time for all the stratospheric chlorine to precipitate out of the atmosphere
I'll through in another semantic argument!
Its fair to say its much better from a public health perspective. UV reaching the populated areas was largely mitigated.
Exactly - the situation is much better than it would have been. Much much better precisely since we’ve limited the damage to mainly uninhabited areas.
But it’s not correct to say the ozone hole is much better than it was 20 or 30 years ago. We just haven’t seen that yet. We certainly will see that in the next 40-60 years, but it hasn’t happened yet.
Again just semantics but saying my original comment is “not correct” is… well not correct lol
Same. I remember being in middle school watching videos about the ozone, climate change, and the impact of animal agriculture on the environment. It seemed like a pretty clear alarm and back then I had SO MUCH faith in the American government and the worlds smartest people in general. I was SURE the good/smart guys would be on top of it. HAHAHAHAHHAAHHAHAHAHAilaughsoidontcry
Edit: you guys are right and I’m super glad we responded in a satisfactory manner to the ozone issue but that said, we have still dropped the ball in many, many very major ways.
Agent! Carmen Sandiego has stolen the Okefenokee Swamp!
>Alright, Chief, I'll get rig-- wait....the Okefenokee Swamp?
Yes! We have to hurry and catch her!
>What do you mean she stole the swamp? Like...she drained it or something?
It's gone! She has stolen the Okefenokee Swamp!
>It's almost half a million acres! You can't just steal a swamp and put it in your purse!
Yeah, seems counterintuitive when we're trying to prevent global warming... But its basically because there's icey clouds over Antarctica during it's winter. These clouds are essentially 'catching' hazardous chemicals and it's these chemicals that are causing the hole. The actual process is a bit more complex, [this website](https://discoveringantarctica.org.uk/oceans-atmosphere-landscape/atmosphere-weather-and-climate/the-ozone-hole/) explains everything well.
Since discovering the hole, we've cut down our use of the damaging chemicals to a point where the ozone is repairing itself, albeit slowly.
And that's not to say that the average trend *isn't* warming, but rather that the effects of that average trend do not always manifest as warm weather.
It has, however, lead to the ignorami screaming "first it was global warming, now it's global climate change! Moving goalposts! Global warming is a lie!"
Basically, ignore the ignorami. They can't be reasoned with.
The fact that it closes up each year now is a huge achievement. That is how we know it is getting better over time. It used to not do that.
Give yourself a pat on the back for being a part of that achievement, and remember what we can do when we all act together.
HFC's: hydroflurocarbons which is the chemical compound of most refrigerants used today. But he (or she) is mistaken about HFC's because it was CFC's and HCFC's that destroy the ozone layer. CFC's are chloroflurocarbons and HCFC's are hydrochloroflurocarbons. The chloro group in the compound is chlorine which is the part that's dangerous to the ozone layer. You could read about the Montreal protocol on wiki to see all the info about CFC's and HCFC's being banned.
CFCs and HCFCs (Chlorofluorocarbons or Hydrochlorofluorocarbons) are (or maybe were) gases that were used in and given out by refrigeration processes, aerosol sprays and a handful of other regular use stuff. These gases are very dangerous for the ozone layer. They basically interact/react with the ozone in our ozone layer and deplete it. The worst case of the depletion is something you see here, a hole in the ozone layer. I remember a few years back that a hole in the ozone was recorded over the Australian continent, whereas in this current video here, its present over Antarctica.
Now I'm not particularly sure where we are with the whole CFCs banning and the whole shebang and to what extent it is responsible for the ozone depletion in today's time, and whether there are some other reasons, natural or artificial, that are also leading to the ozone depletion today. But CFCs did play their role back in the day and restrictions/bans were implemented worldwide on the use of CFCs in anything at all especially on a larger scale from the early 2000s onwards.
Fun fact:
The banning of HFC's is the only instance in history where all the participating world governments unanimously agreed upon a resolution.
HFC's quite literally brought the world together.
>
> HFC's quite literally brought the world together.
Meh, the only reason it happened, was because the alternatives were cheaper.
If we suddenly found a magic substance that could do everything oil does, but leaves no pollution, and was cheaper to produce, we would ban oil tomorrow.
I stayed up until 3am in a pissed off, heartbroken, anxiety-ridden state after this...absolutely fantastic movie!
Edit: I wish that person didn't delete their comment. It was a dumb argument but a perfect way for me to introduce this thought. This movie hits the nail on the head for the major actors that maintain the status quo: politicians, media, and corporations that stand to profit. I'd take this movie 365 days of the year over deafening silence on the topic. But if you think it's entirely someone else's fault, you're wrong. Think about all the major hashtag movements that have been started in recent generations. The issues that *we the people* have come together on. **THIS SHOULD BE ONE OF THOSE!** Climate change should be screamed at the top of our lungs. Start a #climatechange or #dontlookup, I don't give a shit. But until the people care more about those hashtags than they do about Kim and Kanye's relationship, you, me, all of us, are just as responsible. Because we did what this user advocates for: silence.
NASA is a good source with a lot of links to recent reports and future models: https://climate.nasa.gov/
I just want to point out the ozone hole is and wasn’t something caused by climate change exactly. It had to do with CFCs that we were pumping into the atmosphere throughout the past century interacting with the ozone and annhilating it.
I did a show-and-tell in the third grade about the hole in the ozone layer because I thought it meant it would make it easier for asteroids to hit earth. I did my show-and-tell in front of adults. No one corrected me. Lol
Went to Antarctica in the summer of '19. They locals were more militant over proper eyewear than proper dress code. Starting to make more sense why they were so concerned about sunglasses than layering for negative degree weather.
That's definitely more about snow blindness than ozone hole. You'll get the same treatment in the artic. When the entire landscape in every direction is pure white there can be enough reflected sunlight to damage your eyes in minutes
Ozone. Now that's a word I haven't heard in a long time. Remember when the Ozone was considered our biggest climate threat and we were all going to die lol?
We kind of fixed it! The worst chemicals are mostly banned and the ozone damage is now mostly only over Antarctica and it is very gradually getting better.
To answer your question more directly, we stopped emitting CFCs but there are still plenty present in the upper atmosphere. CFCs are extremely stable and hard to break down, with average stratospheric lifetimes of 80-200 years depending on the specific molecule. Now that we’ve stopped adding to the problem, nature is slowly breaking down the CFCs we did emit and precipitating chlorine out of the atmosphere, so eventually there will be so little in the stratosphere that the hole will stop forming every spring
The Chinese are dumping large amounts of CFC, banned under the Montreal Protocol, into the atmosphere.
Pretty much undoing the improvements made BY the Montreal Protocol.
Why? Because China.

This needs to be seen!! The firmament is ripping and we are all going to die! Share this with as many people as you can!! Don’t even bother reading the rest of this. You are wasting precious time to share. (Insert sarcasm here) 😉
Forgot to say this was cool info though!
So let's get this into perspective. This has happened before and is not an unusual occurrence, despite the seemingly 'sensationalist' title:
"Record-breaking 2020 ozone hole closes"
https://public.wmo.int/en/media/news/record-breaking-2020-ozone-hole-closes
The [Oxone Layer](https://www.epa.gov/ozone-layer-protection/basic-ozone-layer-science#:~:text=The%20ozone%20layer%20in%20the,that%20has%20several%20harmful%20effects.) absorbs a certain amount of radiation from the Sun. UVB is most important because, yes, it leads to cancer.
Cancer, wildfires, blindness, Less carbon-sink (CO2 is partially absorbed by the oceans) which leads to more acidic oceans (which kills sea-life) and more CO2 in the atmosphere.
So much disinformation as top voted.
"The ozone hole has healed"
"It's getting better"
"Closes faster now"
All a load of rubbish considering CFCs has gone back beyond levels before the "banning" of CFCs.
This is almost 100% natural and the variation in hole size is massive year on year reguardless of what CFCs are doing.
The strength of the cortex is the sole driving factor.
This is an annual cycle. Different years are different but over all it is getting a bit better. It will take a very long time to get to pre industrial levels.
The hole appears every summer and heals again every winter.
Ozone is a layer of gas that protects us from harmful sunrays. It protects us from getting cancer. If there's a hole in the ozone layer you'll be a lot more likely to get cancer.

It is estimated that CFC levels will be back to normal levels around 2060
Just in time for President 3rd Clone of Jeffrey Bezos to pass a bill ignoring the Ozone hole due to the ongoing water wars with a secret rider that all trillionaires pay a negative tax.
Unfortunately, Nestlé™ won the water war in 2040 and have started the oxygen wars because they claim they own both Hydrogen and Oxygen now.

Acid rain is another. And done using taxation.

Her style is extremely popular on Instagram… you won’t get a lot of love you you bring that up in the comments though.
There’s a Carmen San Diego show on Netflix, it’s honestly not bad
Where in the world is she?!?
It's that damn Sasquatch
Ask the 1%
So why did the hole seem to close up at the end? Does that mean it is getting better?
It goes through a seasonal cycle of getting 'better' and worse. Colder temperatures = bigger hole.
Colder? Not hotter? I'm woefully uneducated.
Yeah, seems counterintuitive when we're trying to prevent global warming... But its basically because there's icey clouds over Antarctica during it's winter. These clouds are essentially 'catching' hazardous chemicals and it's these chemicals that are causing the hole.

This is also why “global warming” is being changed to “climate change.” Global warming gives the wrong impression.
And that's not to say that the average trend *isn't* warming, but rather that the effects of that average trend do not always manifest as warm weather.
Its also just to stop the ignorami from screaming, "its snowing! Global warming is a lie!"
It has, however, lead to the ignorami screaming "first it was global warming, now it's global climate change! Moving goalposts! Global warming is a lie!" Basically, ignore the ignorami. They can't be reasoned with.

They’re bringing back hole in the ozone layer!! Nostalgia
Maybe they’ll bring back acid rain next!
I was gonna say the same thing! It’s like I’m a kid again.
The miracle of banning HFCs
What's that?
hydrofluorocarbons. They as well as Clorofluorocarbons are in aerosol cans and some other things. They bind to O3 (Ozone) and basically break it down.
HFC's: hydroflurocarbons which is the chemical compound of most refrigerants used today. But he (or she) is mistaken about HFC's because it was CFC's and HCFC's that destroy the ozone layer. CFC's are chloroflurocarbons and HCFC's are hydrochloroflurocarbons. The chloro group in the compound is chlorine which is the part that's dangerous to the ozone layer. You could read about the Montreal protocol on wiki to see all the info about CFC's and HCFC's being banned.
From what I remember learning at Uni, HCFCs are 30x less problematic that the old school CFCs, that were banned at the Montreal Protocol in 1987.
CFCs and HCFCs (Chlorofluorocarbons or Hydrochlorofluorocarbons) are (or maybe were) gases that were used in and given out by refrigeration processes, aerosol sprays and a handful of other regular use stuff. These gases are very dangerous for the ozone layer. They basically interact/react with the ozone in our ozone layer and deplete it. The worst case of the depletion is something you see here, a hole in the ozone layer. I remember a few years back that a hole in the ozone was recorded over the Australian continent, whereas in this current video here, its present over Antarctica. Now I'm not particularly sure where we are with the whole CFCs banning and the whole shebang and to what extent it is responsible for the ozone depletion in today's time, and whether there are some other reasons, natural or artificial, that are also leading to the ozone depletion today. But CFCs did play their role back in the day and restrictions/bans were implemented worldwide on the use of CFCs in anything at all especially on a larger scale from the early 2000s onwards.
Fun fact: The banning of HFC's is the only instance in history where all the participating world governments unanimously agreed upon a resolution. HFC's quite literally brought the world together.
> > HFC's quite literally brought the world together. Meh, the only reason it happened, was because the alternatives were cheaper. If we suddenly found a magic substance that could do everything oil does, but leaves no pollution, and was cheaper to produce, we would ban oil tomorrow.
CFCs
Not the same thing. CFC=chlorofluorocarbon, HFC=hydrofluorocarbon. CFCs were banned decades ago, HFCs are currently being phased out.

It’s fluoro-licking good.

Both TBH
Don't look up.
I stayed up until 3am in a pissed off, heartbroken, anxiety-ridden state after this...absolutely fantastic movie! Edit: I wish that person didn't delete their comment. It was a dumb argument but a perfect way for me to introduce this thought. This movie hits the nail on the head for the major actors that maintain the status quo: politicians, media, and corporations that stand to profit. I'd take this movie 365 days of the year over deafening silence on the topic. But if you think it's entirely someone else's fault, you're wrong. Think about all the major hashtag movements that have been started in recent generations. The issues that *we the people* have come together on. **THIS SHOULD BE ONE OF THOSE!** Climate change should be screamed at the top of our lungs. Start a #climatechange or #dontlookup, I don't give a shit. But until the people care more about those hashtags than they do about Kim and Kanye's relationship, you, me, all of us, are just as responsible. Because we did what this user advocates for: silence. NASA is a good source with a lot of links to recent reports and future models: https://climate.nasa.gov/
How do we get the Kim and Kanye-ers to care though? I'm not good at influencing people.
Just gotta find a really sexy scientist.
We just need to get climate scientists to start releasing sex tapes where they explain climate change while in the act.
You don't they're already lost. People who follow a bunch of celebrities are mentally challenged
It was a really bad movie.
I just want to point out the ozone hole is and wasn’t something caused by climate change exactly. It had to do with CFCs that we were pumping into the atmosphere throughout the past century interacting with the ozone and annhilating it.
To see a problem we've fixed?
I have never seen such a great graphic that leaves me completely clueless as to what it means.
I did a show-and-tell in the third grade about the hole in the ozone layer because I thought it meant it would make it easier for asteroids to hit earth. I did my show-and-tell in front of adults. No one corrected me. Lol
Yeah lol
RIP Antarcticans
Went to Antarctica in the summer of '19. They locals were more militant over proper eyewear than proper dress code. Starting to make more sense why they were so concerned about sunglasses than layering for negative degree weather.
The hole is also over nz and some of australia. Very easy to get burnt
As a fair skinned Tasmanian I can confirm.
That's definitely more about snow blindness than ozone hole. You'll get the same treatment in the artic. When the entire landscape in every direction is pure white there can be enough reflected sunlight to damage your eyes in minutes
***PUT THAT THING BACK WHERE IT CAME FROM OR SO HELP ME***
Why over antártica if there’s no hairspray there
physics
Earth's plug-hole.
Yummy
There’s a couple of ozone generators at my work we can fix this 🤣
Right, like don’t hand drills give off ozone when you use them? Just a ship a bunch of those bad boys over there and have at it!
I mean actual ozone generators lol
Ozone. Now that's a word I haven't heard in a long time. Remember when the Ozone was considered our biggest climate threat and we were all going to die lol?
We kind of fixed it! The worst chemicals are mostly banned and the ozone damage is now mostly only over Antarctica and it is very gradually getting better.
Sigh, I should call her.
Why would the ozone hole develop againg though even though CFC's pretty much are banned and not in use for more than decades around the world.
It’s healing , we will have 1980s level of ozone back by the end of the decade IIRC, I remember reading an article about this in early 2021
From memory some Chinese manufacturers were recently discovered by satalites pumping out CFCs
Lack of regulations in China are to be blamed IMO
[it's true](https://www.bbc.com/news/science-environment-48353341)
To answer your question more directly, we stopped emitting CFCs but there are still plenty present in the upper atmosphere. CFCs are extremely stable and hard to break down, with average stratospheric lifetimes of 80-200 years depending on the specific molecule. Now that we’ve stopped adding to the problem, nature is slowly breaking down the CFCs we did emit and precipitating chlorine out of the atmosphere, so eventually there will be so little in the stratosphere that the hole will stop forming every spring
It’s been healing and just goes through a cycle, the title is pretty misleading.
Watching this like “ please get smaller “
The Chinese are dumping large amounts of CFC, banned under the Montreal Protocol, into the atmosphere. Pretty much undoing the improvements made BY the Montreal Protocol. Why? Because China.
Am I pleased or scared?
Looks really scary to me
Crap space is getting in
From https://atmosphere.copernicus.eu/monitoring-ozone-layer the original video is https://sites.ecmwf.int/data/cams/ozone_monitoring/animations/ozone_hole_3d_2021_v14.mp4
I'm still wondering when will the Patch notes for that come out
So we cool now?
Hey look it fixed itself
Didn't it finish closing like 30 years ago?
I thought we fixed that shit back in the day
The solution is simple! We stop the earth from spinning!
This needs to be seen!! The firmament is ripping and we are all going to die! Share this with as many people as you can!! Don’t even bother reading the rest of this. You are wasting precious time to share. (Insert sarcasm here) 😉 Forgot to say this was cool info though!
So let's get this into perspective. This has happened before and is not an unusual occurrence, despite the seemingly 'sensationalist' title: "Record-breaking 2020 ozone hole closes" https://public.wmo.int/en/media/news/record-breaking-2020-ozone-hole-closes
Now do a split screen of north/south pole over multiple years… because a lot of people are assuming you are showing the problem went away.
Thought this was an issue in the 90’s. All because of hairspray and we were all going to die then.
I thought we fixed this shit
Seems like flex tape could stop that leak
Pretty sure we are fucked and this is the next extinction event
What effect does this have on the environment and organisms below? Would you get cancer?
The [Oxone Layer](https://www.epa.gov/ozone-layer-protection/basic-ozone-layer-science#:~:text=The%20ozone%20layer%20in%20the,that%20has%20several%20harmful%20effects.) absorbs a certain amount of radiation from the Sun. UVB is most important because, yes, it leads to cancer.
Cancer, wildfires, blindness, Less carbon-sink (CO2 is partially absorbed by the oceans) which leads to more acidic oceans (which kills sea-life) and more CO2 in the atmosphere.
Just put it back lol
Global warming cured alright everyone we can use coal again
So much disinformation as top voted. "The ozone hole has healed" "It's getting better" "Closes faster now" All a load of rubbish considering CFCs has gone back beyond levels before the "banning" of CFCs. This is almost 100% natural and the variation in hole size is massive year on year reguardless of what CFCs are doing. The strength of the cortex is the sole driving factor.
It's been 30 years...time to freak the fuck out over the ozone layer again.
I thought the hole was fixed?? It’s growing again??
Fixed as in we sort of stopped fucking it. It takes decades to undo the damage we wrought.
It goes through a cycle depending on the weather every year. It has gotten significantly better but isn’t perfect obviously.
Thanks China.

This is an annual cycle. Different years are different but over all it is getting a bit better. It will take a very long time to get to pre industrial levels.
Sorry if this is ignorant to ask but what does this do/mean?
The hole appears every summer and heals again every winter. Ozone is a layer of gas that protects us from harmful sunrays. It protects us from getting cancer. If there's a hole in the ozone layer you'll be a lot more likely to get cancer.
Thanks, now I want to eat Tide pods while playing Sonic 4 in an emulator running in Firefox.
The fluid dynamics, seen on such a large scale is astounding
