Stratospheric Ozone

[@MonicaFrenchBaltimore]

I am honestly stuck on "by the time we get to 2060, essentially, all of that ozone is gone... all of that protection as well." That is a terrifying statement!

[@unpain0334]

uhm. he said it's 'what would have happened' if CFCs were still produced if it wasn't thanks to the montreal protocol. not sure if u were still interested since this comment was one year ago but... hey, why not answer.

[@garyha2650]

Sleep well. There are really only two ways ozone can disappear: 1. The sun turns off. 2. No oxygen available.

[@FailureTillSuccess01]

@@garyha2650 If either of those happen we have bigger issues than the ozone being depleted.

[@Plumb0z]

you will help me pass my final today!

[@lianxie5582]

This was presented in such a great structure! Loved the end recap + visual memory builder!

[@studywithme5998]

how lovely it is to be studying this lesson for your final exam when you have a terrible sunburn because you were too stubborn and didn't apply sunscreen when you went swimming yesterday.... very lovely indeed!

[@bowtieteddy]

For anyone else who got the assignment I'm doing lol: What is the difference between "good" and "bad" ozone? 1:35 What are CFC's and how do they destroy the ozone? 4:44 How is ozone formed and destroyed? 2:20 Where did the hole develop in the ozone and why did it happen there? 5:33 Explain the Montreal Protocol and how it has helped fix the ozone layer 5:48

[@surendrapalsingh9153]

Great video. Nicely explained the underlying mechanism on how ozone is produced and depleted. Thanks sir :)

[@andrew1haddad]

@ 5:20 What you mean to say is its acting as a catalyst thank you very much! great video!

[@clouddust8696]

your videos made me get a 6/7 on my IB examinations!!! you are great!

[@JacquelineTrudel]

I LOVE YOU! THANK YOU! Your videos are so helpful. You summarize everything so beautifully with your diagram. I subbed :D I'm going to need you throughout university.

[@Dave-qj1yg]

Good presentation. Quick, clear and concise. And all withing my attention span.

[@mainukalita3784]

This is so wonderfully explained.excellent

[@rashadal5545]

4:13 "Then we make that good old fashioned oxygen again" LOL

[@dredivany3019]

Thank you for your efforts

[@ProfessionalTycoons]

Thank god for the Montreal Protocol

[@89TNash]

Wish I had you for class i knew about this when I took environmental chemistry and air pollution class

[@kulsoomnadeem3238]

TYSM I HAVE A BIO TEST TOMORROW AND THIS HELPED SM

[@vishalmangaraj]

This is super helpful 👌, thank you sir

[@ellafrancesscott1542]

you’re saving my apes grade thank u

[@dampudulom3199]

Thank you! I wish you were my teacher i would not be struggling so much now.

[@Echodonut]

Quite helpful indeed! I don't study the environment, and did not really know how the ozone-CFC interaction worked. But now I am interested. How does CO2 influence ozone on a molecular level?

[@woutervaneetvelde566]

It doesn't. CO2 reflects light (IR) making the earth warmer, the so-called greenhouse effect :)

[@k-easy2389]

Teacher: kids make sure to do ur homework! Me: hehe copy

[@Gameplayery]

just a headsUp, the annotations don't work at the end of the video, but the information itself was immensly helpfull

[@ibraheemali9541]

Thankyou for the sinplified concepts....Can you plz explain the scientific backing of 1. using ozone generators to clean the air 2. using ozone therapy to treat cancer 3 water treated with ozone for purification?

[@odinakaobi6889]

very nice and comprehensible

[@arsenalsoccer03]

Sooo helpful! thank you so much.

[@sweetGirl-it7eg]

thank you...... ☺ am one of your subscriber

[@aribahwangde1410]

Very very helpful couldn't clear the concept before this...Thank you sooooo much. The flow chart was really easy to understand and made the concept crystal clear !

[@commonman8150]

thanks enjoyed watching

[@zinasantana]

very helpful many thanks!

[@marissalopez8415]

Thank you! It helped a bunch.

[@jordybotello6506]

Thanks for the great video

[@michalpaniry8116]

this was so helpful thank you so much!! :)

[@simplybre6364]

THANK YOU SOOOOO MUCH 💓

[@AustinLan]

Great video but one very picky detail was that you referred to the chlorine atoms as enzymes, when the more correct term would be a catalyst since chlorine is obviously not a protein nor an organic compound. Overall informative and well presented!

[@chrisharrel8837]

Great video teach, thanks!

[@LoanNguyen-nj8tu]

Thank you.

[@ethanpennington692]

... I'm looking and can't seem to find any info on it but here is are questions. How would Medical Ozone affect the Stratospheric Ozone; are they extremely different and if not could we use the Medical Ozone to replace the lost Stratospheric Ozone, and if it affects in a bad way Any ideas on how to make generators to create a Stratospheric Ozone??

[@tropolite]

So how did the freon which is far heavier then oxygen get up 10-50km into the stratosphere? If the Sun is the cycle to create Ozone O3 then how are the holes in the stratosphere and more importantly why are these holes only above the polar regions? Is it because these polar regions are dark for around 50% of the year? Hmmm. Somethings doesn't add up.

[@garyha2650]

And why not the north pole where the evil hair spray cans were

[@yousefal2837]

Now I partially now how and what is ozone holes , thanks

[@littleangel5711]

Can you plz tell me why it does not diifuse

[@hg2.]

Does the fact that there is 6 months of darkness at the south pole contribute to lack of ozone there? Why doesn't Clorox, pool chlorine, or chlorine from seawater (NaCl "salt water) deplete ozone? Why do CFC's only deplete ozone at the south pole? Why are CFCs the only source of high-atmosphere chlorine? Being heavier than air, how do CFCs reach the stratosphere, which starts 6 miles up? Being heavier than air, what happens to CFCs when released into the atmosphere?

[@UrbanSoundAtSbcGl]

Nice production and illustration, but it suggests the production of CFC's has come under control. Unfortunately recent data shows the reversal of Ozone depletion is again losing the battle as the continued and growing use of less potent CFC's along with, aged leakage and still other unregulated countries increasing uses of R11 and R22 continue to create pervasive and dangerous releases of CFC. Our tendency is to suggest CO2 is the culprit to solve climate change. I'm afraid we're heading toward a dangerous outcome by failing to recognize the seriousness of this error. Thanks again for a nice production.

[@cc3822]

It seems like where to focus on CO2. We need to be more focused on gas/chemicals that have more damaging outcomes.

[@eddiejamal1953]

Yes, it was :) thanks.

[@INAYATULLAHSHEIKH]

[@holdenshropshire5543]

What is the Stratospheric Ozone?

[@hg2.]

If the ozone hole was "discovered" in the late 70s with satellite imagery, how do we know it wasn't there all along?

[@billdungsroman101]

Because we’ve seen it deteriorate further over time, and at a relatively proportional rate to the average increase in CO2.

[@thegoodlydragon7452]

Could we just fill the stratosphere with ozone so that we never need to worry about sunscreen or skin cancer? Why is that not possible?

[@ELIT3Terminator]

Week to go!!

[@kevinarackaparambil2724]

[@Thegreatmattimo]

“What humans did “ aha like he isn’t one of us

[@jasonraser40]

We need our planes equipped with rasers PSE generators. They can produce ozone in the stratosphere were it belongs.

[@JeremiahKlarman]

Hey can we go on land???

[@instaminox]

The Montreal Protocol Act was in 1986 and not 1989. Thanks for the video!

[@jasonraser40]

Oxygen is heavy. Helium could help it accend. Don't waste it.

Show black people, because our skin is stronger

[@ZeroPointZap]

Our planet is wrapped in an electromagnetic field... The electromagnetic field is a particle collider and smashes oxygen molecules into O3. Ozone ADHERES to the magnetic field (also adheres to a plasma ball)... When they say there is a "hole in the "ozone layer""... What they mean is there is a hole in the electromagnetic field... We already know about the south atlantic anamoly where the "ozone hole" is... You are just regurgitating establishement crap... Why don't you DO SOME EXPERIMENTS ????

[@quetzaIcoatI1]

ZP ZAP haha, holy crap you're a nut. i hope you kept watching the rest of these great videos Mr. Anderson puts out, because you need to educate yourself a bit better.
