Well done. It was by chance that I stumbled upon one of your distillation videos while studying for an Organic I lab final a while ago, glad I did. I enjoy your content and presentation styles.
Very informative video! Thanks for breaking it down stoichiometricly. This leaves me wondering what the rate of loss of Chlorine in the upper atmosphere is due to solar winds…

hg2 I’m an hvac contractor and had to get my EPA card and while I was reading the book about how CFCs were destroying the ozone we are going to replace them with hydrofluorocarbons I thought well that’s a good idea but wouldn’t pools and the chlorine that they put off into the atmosphere be just as bad if not worse than CFCs if what they are saying is true?
@@peterdarlington4117 Right. The EPA instructor in the last video says "... this isn't the chlorine you put in pools..." In other words there's two kinds of chlorine? Meanwhile, there's old ladies in Florida on fixed incomes who are getting told, "If you want AC you have to cough up $5000 to replace that R22 system you've got." And R22 wasn't even banned for ozone depletion by the stupid Montreal Protocol. It was for the stupid "global warming" issue.
The answer is essentially 'because of the weather in the ozone layer'. In order for rapid ozone destruction to happen, clouds (known as PSCs, Stratospheric Clouds Mother of Pearl or Nacreous Clouds) have to form in the ozone layer. In these clouds surface chemistry takes place. This converts chlorine or bromine (from CFCs and other ozone depleting chemicals) into an active form, so that when there is sunlight, ozone is rapidly destroyed. Without the clouds, there is little or no ozone destruction. Only during the Antarctic winter does the atmosphere get cold enough for these clouds to form widely through the centre of the ozone layer. Elsewhere the atmosphere is just too warm and no clouds form. The northern and southern hemispheres have different 'weather' in the ozone layer, and the net result is that the temperature of the Arctic ozone layer during winter is normally some ten degrees warmer than that of the Antarctic. This means that such clouds are rare, but sometimes the 'weather' is colder than normal and they do form. Under these circumstances significant ozone depletion can take place over the Arctic, but it is usually for a much shorter period of time and covers a smaller area than in the Antarctic. www.theozonehole.com/askthescientist.htm
making a molecule out of different atoms occur when the 2 or more share electrons to get the to a stability they have no interest in moving. So O3 is comfy in that alignment, no need to change.
You mentioned we need to get the chlorine out of the atmosphere to restore the equilibrium. How do we do this? I understand lower chlorine emissions to stop it from getting worse, but does the chlorine just go away? Where can the chlorine that is already up there go?

This always confused me. How do the comparatively heavy cfs “reach the upper atmosphere”, (the stratosphere)? How does it then reach the poles where we see lower ozone concentrations? Ozone is naturally formed when the suns light hits oxygen in the stratosphere. And we get the lowest concentration of sunlight at the poles. Would we not therefore expect to find this anyway?
I get this question a lot. Here is my answer: the problem is with the description of "heavy". Yes, their molecular mass is large, but that would imply that gravity is a factor once they are mixed with other gasses. It isn't. Once dispersed into the atmosphere, their mass is practically meaningless (think ideal gas law - show me the term for mass in the ideal gas law). Once they are dispersed, air currents in the atmosphere carry them aloft and spread them out. Think of it this way. Put sugar in a glass of water. Sugar is WAY more dense than water, so it settles to the bottom. Let the solution sit idle for hours... not much happens - still sugar sitting under water. Now, agitate the mixture. The sugar becomes integrated and dispersed (i.e. dissolved) within the water. But sugar is more dense... surely it will settle out over time? Go ahead and wait. It won't happen. Similarly, once these gasses are mixed into the atmosphere they are essentially part of the atmospheric "solution" forever (or until they react/decompose). Where the air goes, they go, and that includes the upper atmosphere.
Great illustration,, thans for explaining so clearly for mostly people like myself who are not in the chemistry filed,, I am studying using CFC in mechanical ventilation and HVAC to generate cold environments for building occupants,, this video encouraged me not to go with refrigerators using CFCs and search for a better solution.
Aren't you wonderful. The sheer stupidity of "ozone depletion" makes "global warming" look mild. You should see what a hellish mess this ozone cr*p is doing to the Air Conditioning business.
the combinations of UV rays and Oxygen produce O3, as long as you have these two things present you will have Ozone. That's why there's a "hole" detected in the south pole or in the north pole depending on the time of year because the sunlight is limited in these areas. That's why there's no 'hole' in the ozone "layer" over LA!
yeah it was a massive scam. How did a heavy gas like CFC go up to the stratosphere. And we make it in such small quantities. It's like saying your piss can destroy the ocean.
Long to explain. First, ozone is mainly produced in the tropics and transported towards the poles (Brewer Doson circulation). In a normal situation, ozone concentration is even higher over the poles because the lifetime of ozone is longer where there is less sun. The ozone hole occurs over the poles (mainly south pole) because a complex chemistry transforms chlorine reservoir molecules into active ones during the winter. The hole forms in spring when light transforms the active chlorine molecules into chlorine atoms that destroy readily ozone through catalytic reactions. The phenomenom occurs only over the poles and only during spring. At higher latitudes, a decrease of the ozone layer was observed, about 5% since the 1970's. This global depletion is due to the release of CFCs and other halogen molecules mainly of industrial origin and to increased emissions of methane (fossil fuel combustion) and of nitrgen protoxyde (from fertilizers). In conclusion, ozone in the ozone layer is not only a question of light but also of more complex processes that destroy ozone differently, depending on the season and the place where you are.@@silasbullard831
When freon molecules are released into the atmosphere and the sun breaks them down, is it only chlorine that reacts with diatomic oxygen molecules? And if that is why? Also, in this example that you gave for Freon 12 , there are 2 Chlorine atoms in Freon 12 so are both of the chlorine atoms released? Or just one of them?
Yeah only the chlorine because it becomes a free radical where it needs an electron to complete the octet rule. It then snatches electron from the O in ozone. The other molecules are fine since they already completed the octet rule.
Great question. Let me preface my response by stating that it is complete speculation. Having said that.... here we go.... A quick search of bond enthalpies shows that vinyl chloride C-Cl bonds have an ever-so-slightly higher bond dissociation energy than methyl chloride, so I doubt that it has much to do with the relative strength of the C-Cl bond itself in these compounds. It is, however, worth noting that vinyl radicals are TERRIBLY unstable, even compared to alkyl radicals. For a haloalkene to generate a chlorine radical, it must also generate a vinyl radical, which is highly disfavored energetically. This might lead one to predict that the necessary homolytic bond dissociation does not happen as readily in the few haloalkenes that manage to reach the upper atmosphere.
Thank you for the response. The speculation is very sounding. But do you mean that the C-Cl bond in the above compounds maybe too strong for even UV radiation to break? (Perhaps because of more s character in sp2 hybrid orbital?) I can hardly find articles or mere information on haloalkene. Just want to know whether they are simply omitted or they are considered but classified as non-ozone depleting substance.
how a single chlorine atom and a single oxygen atom combine to form a ClO? is not chlorine monoxide Cl2O? is it because all of the earlier 3 are unstable? the atomic chlorine, atomic oxygen and the atomic level ClO?
Thanks for the question. There is a lot of chemistry going on the upper atmosphere and this video just scratches the surface. The chlorine radicals eventually encounter another radical of some kind (chlorine or some other naturally occurring radical) and are consumed in reactions in which they are not catalytic. The oxygen radicals shown at 4:49 are there as a consequence of the natural equilibrium between ozone , diatomic oxygen and atomic oxygen species in the upper atmosphere (discussed earlier in the video).
+Marco A.G.J. In situations like this, the radical catalyst eventually reacts with another radical in the termination step (sometimes other catalyst radicals themselves). It is a natural process that takes place over time, so there is not need to actively 'purge out' the catalyst.

Everything that this video explained is true and scientifically accurate, and I commend it for that. What this video does not mention, however, is that the depletion due to CFC's has been estimated to be about 5% of the total layer. To put this in perspective, the natural fluctuations of the Ozone in the atmosphere can reach depletion levels of approximately 50%. In other words, the depletion of Ozone due to natural fluctuations is about ten times greater than that caused by CFC's. Another point that the video failed to mention is the fact that CFC's are only able to cause harm to the Ozone layer at the poles, and are highly unlikely to spread anywhere else in the atmosphere. One final point the video fails to mention is the fact the there is not a single illness or death that has been traced to the depletion of the Ozone layer due to CFC's. These points all make it evident how absurd the levels to which the harms of CFC's have been emphasized truly are.
Cannot agree with you more, I think the most disturbing things is, why is this in any text book as fact, there are far higher chlorine release in nature, example sea water evaporation etc. CFC production is a fraction of what nature does on a daily basis.

Are there any possible methods to prevent chlorine atoms in the stratosphere to bond with ozone? Is it possible to make the chlorine atom bond with another atom?
Our atmosphere is made up of 78% of nitrogen. Nitrogen has an atomic mass of 14. Chlorofluorocarbons have elements that are much heavier in comparison, such as chlorine which has an atomic mass of 35. That being said, the buoyant force of chlorofluorocarbons would not cause it to rise. In fact, it would sink. What am I missing????
@@lesliehorne846 If so, then why is chlorine from pools allowed? Following the same logic, you would need to ban the 1,000,000 swimming pools that are using chlorine for their pool.
It is not actually the buoyancy that makes it rise up but the interaction of the cfc molecules with the atmospheric molecules. The attractive forces of atoms causes the molecules to drift upward in the air causing them to act like a sticky ladder.
@@erichorton1440the chlorine in pools bonds with the water molecules and completes the octet rule. However, in the cfc molecule in the atmosphere, as it is broken by the uv, a free Cl radical is produced which is bad as it undergoes a process of halogenation and steals Oxygen from ozone just to complete the octet rule.

This is correct. Seasonal changes in size are natural. However, trends of increase in the seasonal maximum over decades of time are not natural. It is the decades-long trend of increasing seasonal maximum that is correlated to CFC release. Imagine opening and closing the curtains on a window over and over by exactly the same distance. The size of the opening changes on the SHORT term (during each cycle), but on the LONG term (over many cycles) you quickly reach an equilibrium in which the opening has a static average size per cycle. i.e. the same amount of light per cycle gets through the window. Now imagine that each time you do so, you open the curtains a little more, and close them a little less. The longer-term trend is that the opening is growing and more light is getting through the window in each successive cycle. This is the problem the CFC production and release caused with the ozone layer in the 80s and 90s. The hole still varied in size seasonally, but just about every year during that period, overall it was a little bit larger than the last.
Well this is what I gathered. You are using government data. They only show "holes" in the ozone above the poles and it's always during the winter. The sun doesn't shine there during that time of year. When sunlight hits oxygen it separates into ozone which is a free radical always trying to reattach. When there isn't enough sunlight to form new ozone then we see the holes..it has been happening since the beginning of time. It isn't man that is causing the holes. It is just nature working the way it is meant to be. Go back and look at the south pole during the summer time and you wont see the hole.
I'm not really using anyone's data, just an image from NASA (if you want to call that data, then I won't challenge that), and I definitely am not out to jump on any particular environmentalism bandwagons. Just trying to show the reaction between halogen atoms and ozone. It's a chemistry thing. But since you brought it up... To your point, I don't think anyone disputes that the ozone hole moves and changes in size seasonally, but the overriding trend in recent decades has been that at its largest point in any given year, it has been progressively larger and larger. Your point has to do with seasonal trends, mine has to do with annual and decade-long trends. That would be a bit like comparing apples and oranges. For example: www.environment.gov.au/node/22194 This 25 year pattern of increasing maximum seasonal size is the trend that most scientists point to as a very likely result of the halogen atoms building up in the region from CFC's Thanks for the comment.
I would suggest that you may want to find a good chemistry teacher. Take a few courses in physics as well. The two are inextricably linked. It's certainly not easy. You may have to watch the lectures 10 times. All of a sudden, "eureka", difficult concepts suddenly become clear, and as natural as a walk in the park. That's how to have a realistic picture of phenomena like Ozone Depletion, or Global warming, ("two separate issues"), but they have things in common in terms of complexity, solar radiation, and the absorption of that radiation in it's different frequencies. I suggest (FREE) on line courses, from (Massachusetts Institute of Technology) under (MIT Open Courseware / Video Lectures), with PDF files for course materials if you really want to test yourself. They even offer certificates of completion. When the first sentence you use contains the words, (government data) it gives the impression that (government data) is somehow more, or less dependable than (private data) a very amateurish assessment of the quality of data. The collection, use, testing, and retesting of data and experimentation will show flaws in the data, not an automatic Knee jerk reaction. It gives the impression that your a neophyte, applying right wing anti government mentality to the issue, or applying some sort of anti science religious bias, which destroys your credibility in terms of serious understanding of scientific matters. I could be wrong, but my instincts and experience tell me to be wary of those who use that terminology. Stop listening to idiots on TV (Loose News), and your crazy uncle. Get the facts, and set yourself "free". The courses are fun anyway, you'll see. Better than hangin out at the pool hall.
Peter Mullen Government data is almost always less dependable than private data. At least that's what I think. The government always has agendas. The problem is most people aren't aware of their agendas or they believe that the government is here to help us. They do things like take temp readings in a parking lot in the middle of a city just to get a high reading. I was wrong in my approach, Chem Survival was just explaining a process and I was having a hard typing my comment..I believe I started on it one day and finished the next because I kept getting interrupted. I'll check out the courses you mentioned and thanks for the info.
TheMddddd I appreciate both view points. And I don't necessarily see much of a difference there. The truth that we would so love to overlook in most cases is this: that research is very rarely altruistically motivated. Public or private: someone is paying the bills, and that financier is usually directly (and almost always indirectly) applying pressure to the project to arrive at findings aligned with that financier's interests. The trick is to learn to view results through a filter of healthy skepticism. The key there is the word 'healthy'. To single out government researchers I think is the only mistake that TheMddddd made. Rigorous, healthy debate is always welcomed among scientists, but prejudiced attitude-driven commentary is very often met with a powerful push back in the scientific community. To reiterate my original point. The video is a short attempt to introduce the uninitiated to the reaction mechanisms which most closely explain exactly why the average annual ozone hole size increased over that famous span of time during which CFC's were in wide-spread use. I do not claim to know for a fact that it is the only player, or even the major player, but I can say with certainty as a PhD Chemist and University Professor, the hypothesis has tremendous merit and curtailment of CFC use was definitely the right thing to do. As the years go by and we observe the hole's behavior as the atomic chlorine in the upper atmosphere is naturally cleared, we will come even closer to knowing if it really was the cause!
TheMddddd It worked. That's all I know. I made some and gave it to someone with breast cancer. They were told last Friday that the tumors were no longer visible on the MRI.. the doctor told her not to have the previously recommended mastectomy... It's amazing what one can find on youtube.
This does not make sense. There are no CFCs in northern and southern poles. CFCs are heavy gas. It does not rise easily. You are making short cuts from CFC to Cl.
This is mostly BS. The real reason they made such a stink about CFCs is because the patents had run out and everyone was making them which drove the price down. They couldn’t make money any more so they banned them and started using different refrigerants that were patented.
Very to the point and relevant. This wasnt taught to me in basic chemistry.
That was very informative. I didn't think I would get so much from a 5 minute video.

hg2 I’m an hvac contractor and had to get my EPA card and while I was reading the book about how CFCs were destroying the ozone we are going to replace them with hydrofluorocarbons I thought well that’s a good idea but wouldn’t pools and the chlorine that they put off into the atmosphere be just as bad if not worse than CFCs if what they are saying is true?
@@peterdarlington4117
Right.
The EPA instructor in the last video says "... this isn't the chlorine you put in pools..."
In other words there's two kinds of chlorine?
Meanwhile, there's old ladies in Florida on fixed incomes who are getting told, "If you want AC you have to cough up $5000 to replace that R22 system you've got."
And R22 wasn't even banned for ozone depletion by the stupid Montreal Protocol. It was for the stupid "global warming" issue.
Why do CFC's only deplete ozone at the south pole?
The answer is essentially 'because of the weather in the ozone layer'. In order for rapid ozone destruction to happen, clouds (known as PSCs, Stratospheric Clouds Mother of Pearl or Nacreous Clouds) have to form in the ozone layer. In these clouds surface chemistry takes place. This converts chlorine or bromine (from CFCs and other ozone depleting chemicals) into an active form, so that when there is sunlight, ozone is rapidly destroyed. Without the clouds, there is little or no ozone destruction. Only during the Antarctic winter does the atmosphere get cold enough for these clouds to form widely through the centre of the ozone layer. Elsewhere the atmosphere is just too warm and no clouds form. The northern and southern hemispheres have different 'weather' in the ozone layer, and the net result is that the temperature of the Arctic ozone layer during winter is normally some ten degrees warmer than that of the Antarctic. This means that such clouds are rare, but sometimes the 'weather' is colder than normal and they do form. Under these circumstances significant ozone depletion can take place over the Arctic, but it is usually for a much shorter period of time and covers a smaller area than in the Antarctic.

@@mikearcher9390 chill. from one grammar cop to another: we are losing the battle. :-(
Nice presentation Prof. thank you
You say it goes back to equilibrium but don't state how. If you have a load of O2 how does O2 turn back to O and O3 if theres so much more O2?
making a molecule out of different atoms occur when the 2 or more share electrons to get the to a stability they have no interest in moving. So O3 is comfy in that alignment, no need to change.
You mentioned we need to get the chlorine out of the atmosphere to restore the equilibrium. How do we do this? I understand lower chlorine emissions to stop it from getting worse, but does the chlorine just go away? Where can the chlorine that is already up there go?
A single chlorine atom will continue to deplete many ozone molecules dozens of times until it cannot anymore and is destroyed.
maybe by dispersing atoms that will bond with chlorine to become stable but won't bond with oxygen.
Does the fact that there is 6 months of darkness at the south pole contribute to lack of ozone there?
no
yes, the rxn for ozone is favored by light, so at the same time there's less ozone "regenerating"

Thanks for this video!
This always confused me. How do the comparatively heavy cfs “reach the upper atmosphere”, (the stratosphere)? How does it then reach the poles where we see lower ozone concentrations? Ozone is naturally formed when the suns light hits oxygen in the stratosphere. And we get the lowest concentration of sunlight at the poles. Would we not therefore expect to find this anyway?
I get this question a lot. Here is my answer: the problem is with the description of "heavy". Yes, their molecular mass is large, but that would imply that gravity is a factor once they are mixed with other gasses. It isn't. Once dispersed into the atmosphere, their mass is practically meaningless (think ideal gas law - show me the term for mass in the ideal gas law). Once they are dispersed, air currents in the atmosphere carry them aloft and spread them out.
Think of it this way. Put sugar in a glass of water. Sugar is WAY more dense than water, so it settles to the bottom. Let the solution sit idle for hours... not much happens - still sugar sitting under water. Now, agitate the mixture. The sugar becomes integrated and dispersed (i.e. dissolved) within the water. But sugar is more dense... surely it will settle out over time? Go ahead and wait. It won't happen. Similarly, once these gasses are mixed into the atmosphere they are essentially part of the atmospheric "solution" forever (or until they react/decompose). Where the air goes, they go, and that includes the upper atmosphere.
Great illustration,, thans for explaining so clearly for mostly people like myself who are not in the chemistry filed,, I am studying using CFC in mechanical ventilation and HVAC to generate cold environments for building occupants,, this video encouraged me not to go with refrigerators using CFCs and search for a better solution.
Aren't you wonderful.
The sheer stupidity of "ozone depletion" makes "global warming" look mild.

thanks for using the correct plural, CFCs. I cringe everytime I see 'CFC's' or 'BUS'S'

Ozone layer is recovering
Well explained. Thank you so much🙂
Thank you sir
the combinations of UV rays and Oxygen produce O3, as long as you have these two things present you will have Ozone. That's why there's a "hole" detected in the south pole or in the north pole depending on the time of year because the sunlight is limited in these areas. That's why there's no 'hole' in the ozone "layer" over LA!
yeah it was a massive scam. How did a heavy gas like CFC go up to the stratosphere. And we make it in such small quantities. It's like saying your piss can destroy the ocean.
Absolutely wrong !
@@stephh7034 how?
Long to explain. First, ozone is mainly produced in the tropics and transported towards the poles (Brewer Doson circulation). In a normal situation, ozone concentration is even higher over the poles because the lifetime of ozone is longer where there is less sun. The ozone hole occurs over the poles (mainly south pole) because a complex chemistry transforms chlorine reservoir molecules into active ones during the winter. The hole forms in spring when light transforms the active chlorine molecules into chlorine atoms that destroy readily ozone through catalytic reactions. The phenomenom occurs only over the poles and only during spring. At higher latitudes, a decrease of the ozone layer was observed, about 5% since the 1970's. This global depletion is due to the release of CFCs and other halogen molecules mainly of industrial origin and to increased emissions of methane (fossil fuel combustion) and of nitrgen protoxyde (from fertilizers). In conclusion, ozone in the ozone layer is not only a question of light but also of more complex processes that destroy ozone differently, depending on the season and the place where you are.@@silasbullard831
@@stephh7034 how is ozone produced in the tropics?
When freon molecules are released into the atmosphere and the sun breaks them down, is it only chlorine that reacts with diatomic oxygen molecules? And if that is why? Also, in this example that you gave for Freon 12 , there are 2 Chlorine atoms in Freon 12 so are both of the chlorine atoms released? Or just one of them?
freon molecules does not reach the south poles. there is a hole in the south and north because solar radiation makes O3.
Yeah only the chlorine because it becomes a free radical where it needs an electron to complete the octet rule. It then snatches electron from the O in ozone.
The other molecules are fine since they already completed the octet rule.
este video en español lo tendran?
Wait... Catalysts doesn't change the chemical equilibrium
What is free radical?
A molecule with odd number of valence electron which is unstable and needs to complete the octet rule
Whats the difference between hcfc and cfc?
Tristan Burns one has hydrogen the other doesnt...
Can haloalkenes e.g. C2F2Cl2, C2F3Cl deplete the ozone layer as well? If they can, why aren't they regulated in the Montreal Protocol?
Great question. Let me preface my response by stating that it is complete speculation. Having said that.... here we go....
A quick search of bond enthalpies shows that vinyl chloride C-Cl bonds have an ever-so-slightly higher bond dissociation energy than methyl chloride, so I doubt that it has much to do with the relative strength of the C-Cl bond itself in these compounds.
It is, however, worth noting that vinyl radicals are TERRIBLY unstable, even compared to alkyl radicals. For a haloalkene to generate a chlorine radical, it must also generate a vinyl radical, which is highly disfavored energetically. This might lead one to predict that the necessary homolytic bond dissociation does not happen as readily in the few haloalkenes that manage to reach the upper atmosphere.
Thank you for the response. The speculation is very sounding. But do you mean that the C-Cl bond in the above compounds maybe too strong for even UV radiation to break? (Perhaps because of more s character in sp2 hybrid orbital?) I can hardly find articles or mere information on haloalkene. Just want to know whether they are simply omitted or they are considered but classified as non-ozone depleting substance.
how a single chlorine atom and a single oxygen atom combine to form a ClO? is not chlorine monoxide Cl2O? is it because all of the earlier 3 are unstable? the atomic chlorine, atomic oxygen and the atomic level ClO?
Why does the Cl atom stop after 10's or 100's of thousands of interactions?
4:49 You're showing single oxygen atoms as just sitting around up there?
Thanks for the question. There is a lot of chemistry going on the upper atmosphere and this video just scratches the surface.
The chlorine radicals eventually encounter another radical of some kind (chlorine or some other naturally occurring radical) and are consumed in reactions in which they are not catalytic.
The oxygen radicals shown at 4:49 are there as a consequence of the natural equilibrium between ozone , diatomic oxygen and atomic oxygen species in the upper atmosphere (discussed earlier in the video).
You are a nerd, that's why i like you
How exactly do you purge Cl atoms out?
+Marco A.G.J. In situations like this, the radical catalyst eventually reacts with another radical in the termination step (sometimes other catalyst radicals themselves). It is a natural process that takes place over time, so there is not need to actively 'purge out' the catalyst.
why cant O3 + O be O + O + O2
Life changing! Thank you :)

The Nonsense That is Ozone-Depletion
"Holes" in the ozone argument:
1) Freon is heavier than air: how do molecules heavier than air get to 30,000 feet (the beginning of the stratosphere)?
2) The "hole" in the ozone over the South Pole was "discovered" by satellites in the '80: if it was just "discovered", how do we know IT WASN'T THERE ALL ALONG ? ? ? ?
3) There is a perfectly logical reason why there is less ozone over the polar regions: THERE IS LESS SUNLIGHT THERE TO PRODUCE OZONE IN THE FIRST PLACE, especially in winter ("land of the midnight sun...")
4) Antarctica (South Pole) has the highest average elevation of any continent (8000 ft): Does that have any effect on ozone quantity????? (The North Pole is all at sea level and there is no ozone "hole" there. (Why not?)
5) The offending atom is CHLORINE (very common), not CFCs themselves. The argument goes that the CFCs carry CHLORINE up to the stratosphere. There are other compounds of chlorine in the atmosphere -- that's one of the things you smell when you go to the beach --> "salt water" --> i.e. sodium-chloride. Is the ocean a source of "ozone depleting" chlorine compounds?
6) Most basic of all, ozone (O3) is an EFFECT of UV blockage, not a cause. [O3 is an unstable molecule that needs a lot of energy to produce, e.g. the ozone you smell around arcing engines. There is less ozone at the poles b/c there is less UV to generate it (just like there is less sunlight to keep the place warm in the first place.
I hope the public is beginning to see how dubious this ozone scam is. Monstrous mistakes like this DO happen - think the ban on DDT and malaria deaths.

I don't see any Dupont fingerprints, but maybe that's true.
I blame the the stupid media and the public for falling for it. If we're fooled that easily, "we deserve to get screwed".
The same thing is happening with global warming (right?).
Everything that this video explained is true and scientifically accurate, and I commend it for that. What this video does not mention, however, is that the depletion due to CFC's has been estimated to be about 5% of the total layer. To put this in perspective, the natural fluctuations of the Ozone in the atmosphere can reach depletion levels of approximately 50%. In other words, the depletion of Ozone due to natural fluctuations is about ten times greater than that caused by CFC's. Another point that the video failed to mention is the fact that CFC's are only able to cause harm to the Ozone layer at the poles, and are highly unlikely to spread anywhere else in the atmosphere. One final point the video fails to mention is the fact the there is not a single illness or death that has been traced to the depletion of the Ozone layer due to CFC's. These points all make it evident how absurd the levels to which the harms of CFC's have been emphasized truly are.
plural of CFC IS CFCs, save the apostrophe for 'ownership'!
thank you
Why doesn't Clorox, pool chlorine, or chlorine from seawater (NaCl "salt water) deplete ozone?
Cannot agree with you more, I think the most disturbing things is, why is this in any text book as fact, there are far higher chlorine release in nature, example sea water evaporation etc. CFC production is a fraction of what nature does on a daily basis.

Are there any possible methods to prevent chlorine atoms in the stratosphere to bond with ozone?
Is it possible to make the chlorine atom bond with another atom?
Our atmosphere is made up of 78% of nitrogen. Nitrogen has an atomic mass of 14. Chlorofluorocarbons have elements that are much heavier in comparison, such as chlorine which has an atomic mass of 35. That being said, the buoyant force of chlorofluorocarbons would not cause it to rise. In fact, it would sink. What am I missing????
My guess would be the strength of the global wind/air circulation and rising air from low pressure areas
@@lesliehorne846 If so, then why is chlorine from pools allowed? Following the same logic, you would need to ban the 1,000,000 swimming pools that are using chlorine for their pool.
It is not actually the buoyancy that makes it rise up but the interaction of the cfc molecules with the atmospheric molecules. The attractive forces of atoms causes the molecules to drift upward in the air causing them to act like a sticky ladder.
@@erichorton1440the chlorine in pools bonds with the water molecules and completes the octet rule. However, in the cfc molecule in the atmosphere, as it is broken by the uv, a free Cl radical is produced which is bad as it undergoes a process of halogenation and steals Oxygen from ozone just to complete the octet rule.

The ozone layer changes size seasonally. It has nothing to do with CFCs!
This is correct. Seasonal changes in size are natural. However, trends of increase in the seasonal maximum over decades of time are not natural. It is the decades-long trend of increasing seasonal maximum that is correlated to CFC release.
Imagine opening and closing the curtains on a window over and over by exactly the same distance. The size of the opening changes on the SHORT term (during each cycle), but on the LONG term (over many cycles) you quickly reach an equilibrium in which the opening has a static average size per cycle. i.e. the same amount of light per cycle gets through the window.
Now imagine that each time you do so, you open the curtains a little more, and close them a little less. The longer-term trend is that the opening is growing and more light is getting through the window in each successive cycle. This is the problem the CFC production and release caused with the ozone layer in the 80s and 90s. The hole still varied in size seasonally, but just about every year during that period, overall it was a little bit larger than the last.
Thanks for 'CFCs' and not the moronic CFC's
Well this is what I gathered. You are using government data. They only show "holes" in the ozone above the poles and it's always during the winter. The sun doesn't shine there during that time of year. When sunlight hits oxygen it separates into ozone which is a free radical always trying to reattach. When there isn't enough sunlight to form new ozone then we see the holes..it has been happening since the beginning of time. It isn't man that is causing the holes. It is just nature working the way it is meant to be. Go back and look at the south pole during the summer time and you wont see the hole.
I'm not really using anyone's data, just an image from NASA (if you want to call that data, then I won't challenge that), and I definitely am not out to jump on any particular environmentalism bandwagons. Just trying to show the reaction between halogen atoms and ozone. It's a chemistry thing. But since you brought it up...
To your point, I don't think anyone disputes that the ozone hole moves and changes in size seasonally, but the overriding trend in recent decades has been that at its largest point in any given year, it has been progressively larger and larger. Your point has to do with seasonal trends, mine has to do with annual and decade-long trends. That would be a bit like comparing apples and oranges.
For example:
www.environment.gov.au/node/22194
This 25 year pattern of increasing maximum seasonal size is the trend that most scientists point to as a very likely result of the halogen atoms building up in the region from CFC's
Thanks for the comment.
I would suggest that you may want to find a good chemistry teacher. Take a few courses in physics as well. The two are inextricably linked. It's certainly not easy. You may have to watch the lectures 10 times. All of a sudden, "eureka", difficult concepts suddenly become clear, and as natural as a walk in the park. That's how to have a realistic picture of phenomena like Ozone Depletion, or Global warming, ("two separate issues"), but they have things in common in terms of complexity, solar radiation, and the absorption of that radiation in it's different frequencies.
I suggest (FREE) on line courses, from (Massachusetts Institute of Technology) under (MIT Open Courseware / Video Lectures), with PDF files for course materials if you really want to test yourself. They even offer certificates of completion.
When the first sentence you use contains the words, (government data) it gives the impression that (government data) is somehow more, or less dependable than (private data) a very amateurish assessment of the quality of data. The collection, use, testing, and retesting of data and experimentation will show flaws in the data, not an automatic Knee jerk reaction. It gives the impression that your a neophyte, applying right wing anti government mentality to the issue, or applying some sort of anti science religious bias, which destroys your credibility in terms of serious understanding of scientific matters. I could be wrong, but my instincts and experience tell me to be wary of those who use that terminology. Stop listening to idiots on TV (Loose News), and your crazy uncle. Get the facts, and set yourself "free". The courses are fun anyway, you'll see. Better than hangin out at the pool hall.
Peter Mullen Government data is almost always less dependable than private data. At least that's what I think.
The government always has agendas. The problem is most people aren't aware of their agendas or they believe that the government is here to help us. They do things like take temp readings in a parking lot in the middle of a city just to get a high reading.
I was wrong in my approach, Chem Survival was just explaining a process and I was having a hard typing my comment..I believe I started on it one day and finished the next because I kept getting interrupted.
I'll check out the courses you mentioned and thanks for the info.
TheMddddd I appreciate both view points. And I don't necessarily see much of a difference there. The truth that we would so love to overlook in most cases is this: that research is very rarely altruistically motivated. Public or private: someone is paying the bills, and that financier is usually directly (and almost always indirectly) applying pressure to the project to arrive at findings aligned with that financier's interests. The trick is to learn to view results through a filter of healthy skepticism. The key there is the word 'healthy'.
To single out government researchers I think is the only mistake that TheMddddd made. Rigorous, healthy debate is always welcomed among scientists, but prejudiced attitude-driven commentary is very often met with a powerful push back in the scientific community.
To reiterate my original point. The video is a short attempt to introduce the uninitiated to the reaction mechanisms which most closely explain exactly why the average annual ozone hole size increased over that famous span of time during which CFC's were in wide-spread use. I do not claim to know for a fact that it is the only player, or even the major player, but I can say with certainty as a PhD Chemist and University Professor, the hypothesis has tremendous merit and curtailment of CFC use was definitely the right thing to do.
As the years go by and we observe the hole's behavior as the atomic chlorine in the upper atmosphere is naturally cleared, we will come even closer to knowing if it really was the cause!
TheMddddd It worked. That's all I know. I made some and gave it to someone with breast cancer. They were told last Friday that the tumors were no longer visible on the MRI.. the doctor told her not to have the previously recommended mastectomy... It's amazing what one can find on youtube.
This does not make sense. There are no CFCs in northern and southern poles. CFCs are heavy gas. It does not rise easily. You are making short cuts from CFC to Cl.
Michael, no wonder you're so smart. Bless you for the correct 'CFCs' and not the gross 'CFC's'!
This is mostly BS. The real reason they made such a stink about CFCs is because the patents had run out and everyone was making them which drove the price down. They couldn’t make money any more so they banned them and started using different refrigerants that were patented.
waaaaaay too long for what it should be
Thank you
