In the ’80s, scientists discovered there was a hole in the ozone over the South Pole. A significant layer of gas that deflects much of the sun’s radiation was disappearing much faster than anyone expected. Projections suggested it would collapse by 2050, increasing skin cancer rates, harming crops, and destroying the marine food chain. The situation was dire. But today, we are on the path to recovery.

Dr. Susan Solomon, among other scientists, contributed key findings to understand what was depleting the ozone layer and how to address it. In this video she takes us back to her expedition to Antarctica, breaks down how we managed to fix this huge problem, and looks at our next big environmental challenge - climate change - with the unbridled optimism that drove her to fix the ozone hole.

Further reading:

To learn about the scientific discoveries by Mario J. Molina and F. Sherwood Rowland that kickstarted research into chlorofluorocarbons (CFCs) in the ’70s, take a look at their groundbreaking paper here:

    Hi! Christina here — I wanted to share NASA’s World Avoided scenario with you. As a child of the ’80s, the threat of the ozone hole was always something I was aware of, but this model really helped me understand the catastrophe we would’ve faced had we ignored it: https://earthobservatory.nasa.gov/features/WorldWithoutOzone

      @FULL TILT I'm sorry but I don't agree with your statement, first off there is no proof that we have anything to do with the hole. When we finally got the technology to see the ozone layer the hole was there, we never observed it before. we don't know if it's a natural phenomenon or not. It gets bigger, it gets smaller, last year it closed off. I have to argue that we don't have a full understanding of what's going on like we think we do.

    I was waiting for the pandemic to be mentioned. I read in a news some months or a year ago, that the ozone's been healing faster due to the global pandemic's restrictions. Less people go outside and using stuff that damages the ozone.

    Only 100 companies around the world are responsible for 70% of climate change. Capitalism is the reason we must change the global economic system in order to address many problems, not only poverty but climate change, especially the plant system. It helps and reduces the number of births. It helps and changes the pattern of industry, recycling and lifestyle. In general, the extraction of lithium for electric batteries may be worse than the extraction of petroleum

    I like how she said Practical. Climate change requires far too much public support, for Ozone, it was rejecting CFC and companies used an alternative. Phasing out gas powered cars, machines, meat industry etc is definitely a bigger challenge, but thanks for putting this together, Vox ! It gives us hope that we have come together for mother earth once and we will do it again.

    I guess she needed to add a fourth P to the story: Producers. Back then they directly attacked the producers of the chemical, and therefore went straight to the source. These days the narrative is aimed at the consumers and personal responsibility, a narrative invented by stakeholders such as BP. This ensured that for decades the big players stayed out of the picture. Change isn't possible if that remains the case.

If you're Home Depot and a new air-conditioner comes to market that is cheaper than what you are currently buying and just so happens to be cleaner, you'll go to the cleaner choice if you can.

    (4) evaporates into the atmosphere as the water is used.

    For as long as I've been alive, the media keeps saying we have ten years to fix climate change. Obviously they didn't call it that in the 80s. But it's always ten years. "If we don't change things in ten years we're all dead." You know, it's these companies to blame for selling the public these toxins. Don't blame the common people for this mess when it's DuPont and other.

    That 'more' that needs to be done is to stop ships from burning 'fuel oil' out to sea. It is the most toxic substance in our environment. See 'ship tracks'. Our 'climate change' is caused by climate control. The problem has always been that anything that can used for good has the equal potential to be used for bad. The most naive thing a person can allow themselves to think, self included, is 'but why would they do that?' Emphasis on 'they'. 'They' are not us and do not represent us in any scenario. 'We', us, take care of one back yard at a time. That is how we collectively achieve success. Never concede to the megalomaniacs who claim authority to know better than you. They don't. Their agenda is not our agenda. We are not expendables. There is room for every living soul on this planet, and the condition of the planet is not 'our' fault. Don't accept something that requires us to exit life. Love one another. Best results.

      Grow too much food so when the food truck is empty, it takes back the extra food with blemishes for fertilzer on indoor crops where there's no need for pestcde as there no bugs indoors, you can grow any crop with with above or below ground (mirrored clay wall) vertical farms, magnifying glass panels at ground level, solar 24/7/365 growing seasons, indoor fresh water fish farms, indoor whaling, grow grass and put cows and chickens on it all year round (won't even stink up a metropolitan city in a high rise) plant dirt and grass and cows where torn down factories left concrete waste slabs) in a building grass can be grown in many floor to ceiling returnable plats on a conveyer, that's takes it up to the dairy floors for food where the cows eat it at 3' above the floor, the floor has a squeegee system and the cows are herded from one half of the floor to the other for cleaning: an automated squeege cleans the floor and empties it into a special for drain: the cow manure goes back down in a pipe for fertilizer : ) the floor has a floor washer, like a car wash, but with clean spayed water on the floor and a squeegee system : ) So good Salt water can be separated with oxygen being released like a rain forest to the outside air while the electricity generated disinfects waste water as it makes energy (NASA does this to make cabin oxygen while it releases everything else to space) Everyone uses a small steam distiller to disinfect and remove salt at the sink for drinking and cooking, everyone gets soft water to their house from the ocean, (already has natural salt in it) drag pipelines to every continent, more jobs, and divert river system maybe to deserts to take sea water rise from melting ice caps and maybe restock what used to be an ocean, natural sand filter at least, just don't put sharks in there and you can surf : ) NASA uses electrolysis to make cabin oxygen from water and they release the hydrogen gas to outer space, you could use the h as clean energy and release the oxygen to the planet as a rain forest, drag ocean soft water to municipalities, they use a small steam distiller at the sink for drinking water, everyone's off toilet to tap, and you use electrolysis to disinfect the waste water and make energy. You split the ocean stream for indoor fresh water and salt water fish farming. You build or convert 40 story buildings for indoor farming. Every acre under roof is an 80-120 acre farm, but instead of 12 hours of light, there's solar glass panels and you have 24 hours of light, 12 months of growing instead of 6, so maybe an 80 acre indoors is like 320. You grow too much food so the empty good truck picks up the blemished felt and vegetables for fertilizer. You can have a cow floor, a dairy farm and a chicken floor in what was an office building. One person drives an hour with gas and clogs tollways to drive to a city where someone else has to drive an hour to his town to work. Now they both work from home, they can get paid more and write off an office in their home, empty office building can be converted to indoor farms, and the sprinkler system can be used for irrigation. You can grow every crop in the world, everywhere, indoor, with every climate and 24/7/365 agriculture, and not even smell farm animals in a building For what it costs to build housing here and grow food on welfare, we can pay people who want to go to another country and build indoor farms and drag ocean lines and build clean energy waste water stations. Who wants to get paid to go to south America and maybe even live there? Whether you were from there, want to get paid to go on a humanitarian effort, or maybe move there : ) With today's technology and the skilled people who came here to learn skills, maybe they would love to develop their home turns and make it great, with more than enough food and water and electricity for everyone, everywhere People work for each other for paper and out of an overflow they trade. Everywhere will be a good home for everyone who lives there Food in cold climates can be grown underground in clay dug out cylinders with mirrored walls, solar night lights and heaters and glass solar roofs
