Ozone is formed in the atmosphere through a process called photolysis. This occurs when sunlight interacts with molecules of oxygen (O2) in the upper atmosphere, breaking them apart into individual oxygen atoms (O. These individual oxygen atoms can then react with other O2 molecules to form ozone (O3. The formation of ozone is an important process that helps to protect life on Earth by absorbing harmful ultraviolet radiation from the sun.
The absence of sunlight in Antarctica during the polar winter prevents the formation of ozone molecules through photolysis. Photolysis, as mentioned earlier, requires sunlight to break apart O2 molecules and create the individual oxygen atoms needed to form ozone. Without sunlight, this process cannot occur. Additionally, during the winter months in Antarctica, the temperatures are very low, which can also slow down chemical reactions and make it more difficult for ozone to form. This is one reason why a large ozone hole tends to form over Antarctica during the winter months, as the lack of sunlight and cold temperatures make it difficult for ozone to form and maintain itself in the atmosphere.
So, this so called ozone hole is a natural process, the hole appears during the polar winter and disappears when the region is again exposed to the Sun, and the chemical reactions that enable the formation of ozone molecules is again viable.

I think the biggest problem with the current climate issue is that it s not as readily apparent (even excluding the capitalistic mindset of maintain oil based companies. With the ozone hole, it s pretty obvious to find out you have a hole in the sky that could kill the planet.
With Climate Change, oh, we don t need to do anything, it just makes the planet warmer. By the time we do see anything for climate change, it ll be too late. If you haven t seen the increasing number of natural disasters and the flooding at coastlines, then you re living blindly. Please please, convince our legislature to take action. There s only so much humanity can take now.

Bait and switch. Take a non-controversial topic like the banning of CFCs and smuggle in the controversial one: Climate Change. The two are different problems and require different solutions. Banning, capping, or otherwise limiting CO2 emissions through government fiat will lead to death and suffering. Fuel drives every aspect of our life. If you want to lower emissions the ONLY way we know how right now is to use nuclear power. Too bad the left curtailed its development 50 years ago and to this day still fights against it. Nuclear power is safe, efficient and with increased use will out compete fossil fuels as an energy source.

Pursuing profit at the expense of nature's wellbeing is just a symptom of a deeper underlying issue. Only when we recognize that we are not a separate entity from our environment, will change in a beneficial direction begin to take place. Just because we live behind walls does not mean that we are any different from the organisms that dwell outside of them.

The reason we are still not on the same page about saving the earth is that we don t have enough young people in office who understand these problems. We need to not listen to those who denie facts that are right in their face and that we can see with the web and sataellte data only then can we truly save the earth, and use more green energy.

There is a big caveat that ted-ed failed to mention. Skin cancer has been researched to predominantly affect fair skinned people, while global warming will affect global South, ie, places like Africa and South Asia first even though most of the carbon causing the green house effect today was released by the activities in the western world.

A skin cancer survivor and a chemist happening to be in power of 2 influential countries of the day, just when we needed it most, resulted in the the push needed to ignore the so called debate and do the right thing. I don't know what else Reagan and Thatcher did in power but they were in the right place at the right time.

I remember hearing in this one movie about this girl who berated her sister for using too much hair spray because it would create a hole in the ozone layer. I m pretty sure that was my first introduction to the ozone layer. I m also pretty sure the movie was Ramona and Beezus but I could be wrong

This is what happens when you can actually talk about problems instead of trying to cancel and censor anyone that asks questions or has concerns or heaven forbid voices a different opinion. If there is no open debate then most people will never buy in to whatever solution is pushed.

I remember during the pandemic, when there were almost no cars or crowds. The air in urban areas got so clean! Beaches were empty so turtles thrived! When people got out of the way, nature took over and the environment started to recover. Am I the only one who misses that?

Oh boy, can't wait to hear another TED speaker tell us how we should all feel guilty for using hairspray in the 80s. I hope their opinion is based on a thorough understanding of atmospheric chemistry and not just some trendy eco-babble they read on a bumper sticker.

Do take a look at CFC11 and CFC12 atmosphere concentrations over time charts. It is actually much higher today than in the 1980s for both of them. If the Ozone layer hole was increasing in the 1980s, why is it DEcreasing today?

Often people ignorantly ask this exact question, thinking that the hole in the ozone layer, just like acid rain, must have been scare propaganda. They cannot grasp the idea that decisive action actually solved the problem.

Politicians disagreed on what to do Some were paid to disagree and some were not.
Also, the only other agreement signed by every country missing mention is the Vienna Convention for a total of 198 countries.

There is an interesting irony, at least in my country, where we are experiencing so much heat that we constantly use ACs (Freon) to cool down, but not realizing that our actions contribute directly to more heat
