I was born in Hobart Tasmania in early 80s. I think it knew about the ozone hole before I hit high school in mid 90s as it engulfed all of Tasmania and a bit of southern Australia. It’s one of the big reasons the Green Party in Australia started, that and due to a dam. It tended to insill a pragmatic view of the environment to that generation of Tasmanian’s I think. Understood environment conservation was important but also having a job Was too
More people need to watch this channel. I stumbled on it when I was looking for info on the Aztecs. I study history and realized I've got a severe lack of knowledge when it comes to Meso-America. Been bouncing all over the place on these videos since.
Ok I’m not claiming to be an expert but I have enough scientific knowledge to say that UV B would not wipe out all life or even all terrestrial life. Life is resilient and there are lots of ways to avoid damage from UVB
@@cimachu Okay, let's rephrase that then. Companies would rather wipe out a large chunk of life on earth, greatly increase cancer rates for everyone, and completely cripple basically all economies. Is that better?
Hi there! I just started watching your videos recently and I honestly do enjoy them. I would, however, like to make a suggestion: include your sources in the description below. I love that your videos make things easy to understand but I would wholeheartedly appreciate if it came with a sense credibility and a chance to read more in depth about the topics. Anyway, kudos for the good videos! Thanks!
Because it was the big scary of the late 90s, you could just be to young. Don't worry in the 80s and early 90s it was the world was going to freeze. And another ice age was starting. Now we have a hole in the ozone and global warming
Which is why I think the environmental problem of global climate changeis not so much in the heads of the people as previous ones. Earlier problems were easily visible. Foams and chemicals in rivers? Easily visible. Smog poluting the air? Visible, you could even taste and smell them. And as shown here in the video, you showed them a map, and they easily saw the affected areas. But with global climage change, it is not as easy, as there is a lot more things with graphs and numbers to show to people. Possibly we need a new marketing campaign to make it more easily understandable for people to realize how threatening it all can be.
Do keep in mind that things like melting ice caps are very easily visible. What it is lacking is a sense of urgency and proximity. Dying is very close to one's person. The artic isn't all that relatable. But realizing that a deadly problem will come your way in your lifetime and that death is certain is a very powerful message which global warming simply lacks. Saying sealrvels will rise over 100 years makes most people think "Ill be dead by then, I don't care". Which is also why I personally think that the new generation (born after 2000) is a lot more pro-green because it will affect them the most.
I don't think they're evil corporations like the climate alarmists say just lazy and irresponsible, I think we can all agree, hey let's clean up our home it's the only planet we have ok? Not if you don't do it you are evil!!!!! You a literally hitler!!!! That's how you create detractors and skeptics and how you kill your message. I don't like climate skeptics but I don't like climate alarmists either. I just focus on what NASA and the real scientists say not the angry mob.
The thing is, all the things you described were problems that already happened that needed solving. Climate change is a future problem, which for some reason, for some people, it means it doesn't matter. Yet.
So none of you noticed the new temperature records the past few years? Warmer summers the past few years? Ice caps melting? A lot less snow in the winters? Well ... I guess people want to be blind to the obvious.
I do remember that. The amount of dystopia sci-fi where everyone lives in a tunnel or wear toxic sunscreen due to Ozone layer destruction. It seems to work. Sad that people no longer have that drive for Climate Change...even the disaster movies *cough* The Day After Tomorrow */cough*, except Earth 2100 and a global government simulator game, with such messages to have concerns about Climate Change seems to be needlessly optimistic instead of horrors, sidenotes, and scare-em-straight.
@Kraptonite sadly, when the majority of the population has no interest in science or world affairs, it is difficult to attain an enlightened civilisation. As long as trash like "living with the Kardashians" is viable TV, you know society is fucked.
@@bigsmall246, it might have something to do with context. If the same guy ranting on your screen about climate change, is also the guy ranting about transgenderism, racism, etc, you tend to just say "okay, he's a loony toon." I for one, understand the science behind global climate change, but I cannot endorse, vote, or support any major action on it until the scientific community boots out the political hucksters tacking on a whole bunch of crap that have nothing to do with climate change.

The "Expected light" graph is actually a theoretically wrong graph which was proven wrong in the UV catastrophe experiment and gave rise to Max Planck's idea of quantised light.
That graph during 1:50 has no context to the ozone layer. It's actually a graph explaining the UV catastrophe and represents the energy radiated by any hot body. The "actual light detected" line is the light the sun emits, it's just that there're further negative dips in the UV region over and above this. Nice video though :)
If I like this video you ask? I LOVE IT! As a PhD student in microbiology, you can't imagine how amazing I find that once in human history the whole world heard scientist and acted preventively trusting their findings and predictions. BEAUTIFUL.

Given no one is making clear policies to combat global warming and many nations like the US already left preestabled treaties that were made to combat climate change.

I always wondered why the ozone hole was considered to be caused by humans and it was over the South Pole when most of the people and industrial activity were in the Northern Hemisphere and virtually none of the people and industrial activity was in Antarctica.
"Polar vortex" is the reason, it accumulates the FCKW we emit around the globe to the poles (we have verified this with weather balloons fitted with FCKW detectors).

This is a nice explanation, but here is also another reason international cooperation worked so well: practical alternatives were discovered (HFCs). The current climate crisis is much much harder to solve as energy is the base for life and transformation of goods.
This is the first video I've ever watched of yours, but I have to admit I liked it. I actually learned something which is rare on RUclips, and I didn't hate you by the end of it because you kept it on point and factual. You earned a new fan =p also, knowing the ozone layer is projected to be sealed by 2060 is awesome (that's what I learned) because that means in my life time we may be able to go outside and not get turned into crispy critters by the time I'm a senior. These days I can get burned within an hour of being outside, I look forward to the day when that is more like 8 hours
I appreciate the overall optimistic tone of this video. I really think climate change doubters will come around over the next decade as the evidence is getting pretty indisputable year by year. I just hope its not too late to take corrective actions by then and my great grand children will be dealing with a venus like run away green house in their life time.
Don't forget about the next steps: 1) CC is a problem but it is too expensive to solve 2) CC is now unsolvable so let's just party until we all die. In Germany, we are on step 1: Planning for 3C, on the way to 4C. And don't ask about the worst case scenario: You "likely" get 1.5-4.5 per doubling of CO2 (most likely value = 3C). If you get very unlucky, it gets way worse.
getting pretty indisputable? From what I've known it's been indisputable for at least 20 years now, it's just some people stick their fingers in their ears whenever they see the evidence. the fact that people simply denying cold hard evidence is what has let us not work on this issue is astounding to me
@@Lysergic_cold hard evidence like what? Like the government saying our gas burning vehicles are the problem, not the chemical that a few decades ago they said was completely safe?

So hypothetically if the ozone layer disappears enough, would the creatures in the ocean live? If not the surface level creatures what about the ones in the twilight zone? I’m very curious about this and I want an answer if anyone can answer.
Yes they would still survive. The Earth hasn't had the ozone layer throughout all of history, so early earth actually did have a baren surface just like the video explains. However, life was able to survive in the ocean because water blocks UV-b light (and most light in general) just like ozone does.
Which is why I specifically pointed towards land-based life. The sea would be fine, except the top layer, perhaps and sea animals relying on surface life
Very interesting video, I'd be interested to find out the nature of CFCs and why the hole consecrated over Antarctica despite worldwide emotions then.

Very good point about the marketing of the Ozon safety problem. Just makes me think, why can't we find a similar simplification for Global warming. We seem to need it to solve the problem globally. The Green house effect sounded at least more dangerous than Global warming. How about Earth overheating? Sunlight lock-down? Global Carbon Poisoning? Excellent video! Many thanks.
"Hyper-Absorption of Radiation in our Atmosphere" would probably do the trick. If anyone uses that for their title in an article i simply wish to be credited as a co-signer of the article
Well it also helps that it's easier to just find alternatives to ozone and keep making products to sell, than avoid producing carbon dioxide. Just making electricity can easily produce carbon, and the methods to get around that is more expensive, you can't get in the way of rich people getting richer.
@@polishedmeat6399 nuclear is a time winning alternative, during that time we must figure out another source. but it is important to stop spiting greenhouse gases as soon as posible
@@alonsop9861 by the time we fully convert to nuclear and get enough resources to build all the nuclear plants i think we would already find a alternative source
You neglected to mention that the main difference between CFCs and fossil fuels is that we are WAY more dependent on fossil fuels. Electricity generation and transport are both huge, HUGE economic backbones that cannot be easily replaced. Much more so than hair sprays. We could easily switch to nuclear power, but of course the oil companies would play up irrational fears of nuclear reactor accidents.
@@Lscott-fk2sn people talk about how nuclear waste lasts for centuries and is difficult to contain, but they do not talk about how fossil fuels are creating smog today and killing thousands via lung diseases. Not to mention the economic losses from climate change when crops fail, and the costs to relocate climate refugees
We did it once we can do it again! A Protocol needs to be created for Climate Change - Governments need to do the same to Oil and Electricity companies. We need to put the world first.
Most of it is solving itself already luckily. The age of oil is over, energy is now shifting from resources to technology because of economic incentives. Doing the right thing is no longer an ideology, it is becomming the sensible economic thing to do. There is going to be large disruption in energy and transportation in the 2020's. So that's already positive. It is just the question if it will be in time. Political focus and funding should shift towards co2 extraction from the atmosphere and reforestation.

Okay How about we stop destroying ourselves in the west first and hold the biggest polluters responsible? Better yet we can all switch to Nuclear power! Cheap, efficient, barely polutes...Oh...Right...Activists had a decades long fearmongering campaign since nuclear power is actually A SOLUTION
@@baronvonlimbourgh1716Fails like Chernobyl and Fukushima scare the public into not investing in it. But that's not the whole story both of the times it was a manual error.
No, it actually "heals" itself with the help of wind and storms near the hole, multiple oxygen go up above and heated up by the sun also turn into Ozone gas, which fix the hole faster and increase amount of ozone on the layer
So almost all CFCs was accumulated in Antarctica to produce ozone hole? It sounds very improbable. What if ozone is less in Antarctica (and also in Arctica) because at poles there is less UV light which produce ozone as a reaction between oxygen and UV light?
When i was a child in 1987 there was a tv show called La noticia rebelde (crazy news) They asked the people why would you put into the ozone hole? A man said he would put his furniture( a table and some chairs)
It's too bad more people don't know we solved the problem. I just found out that the hole in the ozone layer was shrinking only a month or so ago. If more people knew about this success story, in might prompt a bigger effort into fighting the current issue of climate change.
Read my other comments on this. But there is one thing you should be aware of. The ozone hole is a VERY different thing than just about all other environmental problems. The ozone hole protects the earth's surface from UV radiation. Without the ozone in the atmosphere UV would reach the Earth's surface. This might give you skin cancer, but that is really a very minor issue. What it would do is kill most of the plants in the world. They would be gone in less than a week. All humans would be dead in six months except those that harvested the oceans. We were really very lucky with the recovery of the ozone layer as it really would have been the end for most of us. By comparison, global warming is a very minor issue.
I remember the Chicken Littles back in the day. First it was acid rain. Second it was a hole in the ozone Third it was global warming Now it's climate change
It would have been nice if you included in your comprehensive discussion, recognition of the Mexican physical chemist, Dr. Mario Molina, and his 2 colleagues who were granted the 1993 Nobel Prize for discovering or making the connection to the CFC induced depletion of the ozone the layer observed over Antarctica from satellite data and his subsequent advocacy of efforts to end the use of CFC's in in manufacturing processes and products.
Not really a reaction in the mainstream sense: 3O2->2O3 Disclaimer: this may be horribly biased, I am not formally educated in either pure or applied chemistry, much less environmental science. I invite anyone more knowledgeable to correct me. What basically happens, as I understand it molecules of O2 are being broken apart under intense ultraviolet light. Now, single atoms of oxigen are not stable and will try to bind to some other unstable molecule. Sure, it may form another O2 molecule, but that wouldn't last, as the ionising radiation would split it just as before. If it binds to two other Oxygen atoms, however, the UV light wouldn't destroy the new O3 molecule, because, as seen in the video, O3 is resistant to it. The caveat is that ozone is destroyed by other natural causes, but as long as we limit insertions of artificial ones, the trend seems to be that more ozone is created than destroyed by natural causes. See this government issued pamphlet (link will download a pdf): www.google.com/url?sa=t&source=web&rct=j&url=www.esrl.noaa.gov/csl/assessments/ozone/2010/twentyquestions/Q2.pdf&ved=2ahUKEwjJke_R5pzqAhUgVBUIHXm8BnQQFjANegQIDBAy&usg=AOvVaw0yg52zKoHnm-BcpMSdagLe&cshid=1593083479981 If you're interested in the formal science regarding this topic, I'm afraid I'm ill-prepared.
what makes me sad is because these science organizations efforts to inform the public and these countries banding together to solve a serious problem there are now deniers that there was even a problem in the first place.

Very interesting video, I'd be interested to find out the nature of CFCs and why the hole consecrated over Antarctica despite worldwide emotions then.
Very good point about the marketing of the Ozon safety problem. Just makes me think, why can't we find a similar simplification for Global warming. We seem to need it to solve the problem globally.
The Green house effect sounded at least more dangerous than Global warming. How about Earth overheating? Sunlight lock-down? Global Carbon Poisoning?
Excellent video! Many thanks.
"Hyper-Absorption of Radiation in our Atmosphere" would probably do the trick. If anyone uses that for their title in an article i simply wish to be credited as a co-signer of the article
or throw in acceleration in there to make people think short-term "The Accelerating Hyper-Absorption of Radiation in our Atmosphere"
Well it also helps that it's easier to just find alternatives to ozone and keep making products to sell, than avoid producing carbon dioxide. Just making electricity can easily produce carbon, and the methods to get around that is more expensive, you can't get in the way of rich people getting richer.
Creating electrucity it's simple, nuclear, the problem is to store it so it can be used in cars or planes (on planes seems imposible)
@@alonsop9861 nuclear and then you deplete all the natural uranium sources. what then
@@polishedmeat6399 nuclear is a time winning alternative, during that time we must figure out another source. but it is important to stop spiting greenhouse gases as soon as posible
@@alonsop9861 by the time we fully convert to nuclear and get enough resources to build all the nuclear plants i think we would already find a alternative source
Better to go nuclear than waiting for that solution you speak of, while still burning oil, gas, and coal.
You neglected to mention that the main difference between CFCs and fossil fuels is that we are WAY more dependent on fossil fuels. Electricity generation and transport are both huge, HUGE economic backbones that cannot be easily replaced. Much more so than hair sprays.
We could easily switch to nuclear power, but of course the oil companies would play up irrational fears of nuclear reactor accidents.
So true we need more nuclear power if people dont want that we will have to wait till the invention of an efficient nuclear fusion machiene
@@Lscott-fk2sn people talk about how nuclear waste lasts for centuries and is difficult to contain, but they do not talk about how fossil fuels are creating smog today and killing thousands via lung diseases. Not to mention the economic losses from climate change when crops fail, and the costs to relocate climate refugees
bigsmall246 so true, additionally more people have died building hydroelectrics than all direct and indirect fatalities from nuclear power
I learned something new today. Your videos are amazing and underrated. I will send to my daughters to learn. thank you for your effort.
why is this just getting recommended now lol this is amazing quality video.
Another great and informative video HS. Dank je wel!
Awesome vid bro. Loved it.
U made me happy by using Minecraft day light sensor
1:21 I like how he used the daylight sensors from Minecraft.
Wonderful content. absolutely love it!
I literally love your videos so much
Ah, this brings me back to my academic fair some odd 10 years ago. Did a paper on ozone, got full marks. My mother was so proud. Lmao
lol the daylight sensors
what are your sources?
Well done. Earned my sub.
I had always known the ozone was dying but I never knew the problem was fixed it's really making me feel safer now thanks for the video
*2:38** I really love you used Minecraft. Daylight sensor* 😀👍
We did it once we can do it again! A Protocol needs to be created for Climate Change - Governments need to do the same to Oil and Electricity companies. We need to put the world first.
True, true, but consider this:
We get sooooo much money!
Most of it is solving itself already luckily.
The age of oil is over, energy is now shifting from resources to technology because of economic incentives.
Doing the right thing is no longer an ideology, it is becomming the sensible economic thing to do.
There is going to be large disruption in energy and transportation in the 2020's. So that's already positive.
It is just the question if it will be in time. Political focus and funding should shift towards co2 extraction from the atmosphere and reforestation.
Okay
How about we stop destroying ourselves in the west first and hold the biggest polluters responsible?
Better yet we can all switch to Nuclear power! Cheap, efficient, barely polutes...Oh...Right...Activists had a decades long fearmongering campaign since nuclear power is actually A SOLUTION
@ no it isn't. It is obsolete technology.
But go ahead and invest in a couple of new nuclear plants 👍
@@baronvonlimbourgh1716Fails like Chernobyl and Fukushima scare the public into not investing in it. But that's not the whole story both of the times it was a manual error.
Whenever I see the thumbnail of this video I think of Fox's shine.
For a video where the science wasnt explained, it felt very scientific
A great video explaining a very useful and applicable method to gain with spread impact.
This gets me so hyped
This is the only science channel that don't seems to give me existential crisis
Phenomenal video.
But how to solve this problem... can we like add ozone to the layer... like add O3 to the atmosphere
No, it actually "heals" itself with the help of wind and storms near the hole, multiple oxygen go up above and heated up by the sun also turn into Ozone gas, which fix the hole faster and increase amount of ozone on the layer
Can you explain how ozone avoids the equilibrium laws of gas I learned in basic science class in grade school?
dude he is history scope not science scope so no
Short answer..it doesnt.
my first watch of this channel. good stuff. i like.
So almost all CFCs was accumulated in Antarctica to produce ozone hole? It sounds very improbable.
What if ozone is less in Antarctica (and also in Arctica) because at poles there is less UV light which produce ozone as a reaction between oxygen and UV light?
12:14 wait. I don't understand this: the map shows the ozone vanishing globally till 2060. But don't we want the opposite?
The bluer it gets the more ozone he just chose a different colour it confused me too at first
@@Lscott-fk2sn yeah a bit unintuitive
Really cool video, I’ve just found out the channel and already subscribed
brilliant video!well done!
You have inspired me
Why was the hole discovered prior to the wide spread use of CFC's? Maybe something else can cause the hole.
This video tells a seriously awesome story.
When i was a child in 1987 there was a tv show called La noticia rebelde (crazy news)
They asked the people why would you put into the ozone hole?
A man said he would put his furniture( a table and some chairs)
Your s's are really sharp, you should consider passing your audio through a low pass to remove some of those high frequencies.
To be honest, China sounds more and more like an antagonist of a story.
11:07
this was epic
It's too bad more people don't know we solved the problem. I just found out that the hole in the ozone layer was shrinking only a month or so ago. If more people knew about this success story, in might prompt a bigger effort into fighting the current issue of climate change.
Read my other comments on this. But there is one thing you should be aware of. The ozone hole is a VERY different thing than just about all other environmental problems. The ozone hole protects the earth's surface from UV radiation. Without the ozone in the atmosphere UV would reach the Earth's surface. This might give you skin cancer, but that is really a very minor issue. What it would do is kill most of the plants in the world. They would be gone in less than a week. All humans would be dead in six months except those that harvested the oceans.
We were really very lucky with the recovery of the ozone layer as it really would have been the end for most of us. By comparison, global warming is a very minor issue.
History scope: *talking about the ozone layer
Me: There's a minecraft block( i forgot what it is called)
Good content, video and narration.. deserve much more views👍👍🍻
I remember the Chicken Littles back in the day.
First it was acid rain.
Second it was a hole in the ozone
Third it was global warming
Now it's climate change
It's enough to make a grown man cry
I like how he used the one minecraft block I cant remember its name, for 1:19
Bruh, I pressed the like button when it was at 6.9k
Nice.
The sun is a deadly lazar.
Not anymore there's a blanket
It would have been nice if you included in your comprehensive discussion, recognition of the Mexican physical chemist, Dr. Mario Molina, and his 2 colleagues who were granted the 1993 Nobel Prize for discovering or making the connection to the CFC induced depletion of the ozone the layer observed over Antarctica from satellite data and his subsequent advocacy of efforts to end the use of CFC's in in manufacturing processes and products.
Tell me how it is repairing
Reaction???
Not really a reaction in the mainstream sense: 3O2->2O3
Disclaimer: this may be horribly biased, I am not formally educated in either pure or applied chemistry, much less environmental science. I invite anyone more knowledgeable to correct me.
What basically happens, as I understand it molecules of O2 are being broken apart under intense ultraviolet light.
Now, single atoms of oxigen are not stable and will try to bind to some other unstable molecule. Sure, it may form another O2 molecule, but that wouldn't last, as the ionising radiation would split it just as before.
If it binds to two other Oxygen atoms, however, the UV light wouldn't destroy the new O3 molecule, because, as seen in the video, O3 is resistant to it.
The caveat is that ozone is destroyed by other natural causes, but as long as we limit insertions of artificial ones, the trend seems to be that more ozone is created than destroyed by natural causes.
See this government issued pamphlet (link will download a pdf):

If you're interested in the formal science regarding this topic, I'm afraid I'm ill-prepared.
thanks for this video it helped me understand a lot!
This really takes "The sun is a deadly Lazer" to a hole nother' level.
Absolutely wonderful content.
we flex-taped the ozone
Got Hope back, thanks
YOU COMPLETELY FORGOT TO SAY THIS:
In the end cows farts saved us: Methane reacts with the CFC molecules, it destroys them.
Put solar powered ozone generators on Antartica - problem solved. 😎
You cant build shit there you know
Love the Data reference XD
Someone : Complains about anything*
What you should tell them : It saved your life!
Why is the ozone layer above Antarctica and not maybe above the artic circle? Aren't most of the countries who used cfcs in the north?
Just the right amount of consending to make a point
what makes me sad is because these science organizations efforts to inform the public and these countries banding together to solve a serious problem there are now deniers that there was even a problem in the first place.
Good explanation 👌
