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.

  • 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: earthobservatory.nasa.gov/features/WorldWithoutOzone Thanks so much for watching our video! Let us know what you think in the comments below.

  • We go round and round, but in the end it’s about huge companies and corporations and their lobbying. Once they had no use for the compound and had substitutes it was easy to let it go. It’s all about these small bureaucracies and their strong influence and power on the governments and people.

  • From around the turn of the century to about 1980 there was a short cooling period and some every harsh winters. Many scientific papers discussing the possibility of an approaching ice age? The importance of putting uncertainty bars on data. Excellent video. Can we do the same for fossil fuels? It's far too easy to pick on the odd vintage preserved steam locomotive, or classic car? How about the 9,000,000,000 tons of coal per year used for electricity (that's nearly double what it was 15 years ago?).

  • El cambio climático es un proceso natural de la tierra, todos estos movimientos ambientalistas solo son incentivados por politicos y empresarios como una forma de ganar dinero y votos. Los volcanes liberan CFC que agotan el ozono a la atmósfera. Una sola erupción expulsa más CFC a la atmósfera que todos los CFC utilizados por la humanidad desde que fueron descubiertos y utilizados en latas de aerosol y otras aplicaciones industriales y de consumo. Todos esos acuerdos firmados por politicos solo fueron hechos para beneficiar a las grandes empresas que ahora se aprovechan de todos estos movimientos ambientalistas llenos de jovenes ignorantes a los cueles ahora se les cobra el doble de precio por productos que "no dañan la capa de ozono".

  • Climate change is a natural process of the earth, all these environmental movements are only encouraged by politicians and businessmen as a way to earn money and votes. Volcanoes release ozone-depleting CFCs into the atmosphere. A single eruption expels more CFCs into the atmosphere than all the CFCs used by mankind since they were discovered and used in aerosol cans and other industrial and consumer applications. All those agreements signed by politicians were only made to benefit large companies that now take advantage of all these environmental movements full of ignorant young people who are now charged double the price for products that "do not damage the ozone layer" .

The ozone hole was gradually "closed" via the proses of compensation & redistribution by the healthier global areas.... ; however the global ozone thickness has somewhat reduced....! The compensation & re-distribution proses was made possible & quickly after the Montreal Treaty was executed...! This somewhat positive news has no way reduced the threat of Global Warming which is continually invading this Planets health...! The INTERNATIONAL Community must come together as one, to save this Planet from our destructive habits..!

  • The 3 Ps mentioned do not seem to apply to climate change (yet) - personal: most of the developed world lives sheltered away from problems caused by global warming. sure there's an extra hot summer here and there but it's not catastrophic. - perceptible: yes the earth is warming, but it is hard to perceive the causal effect from warmer temperatures to natural disasters (floods, forrest fires, tornados). natural disasters have always happened and will happen regardless of climate change. - practical: in the ozone problem, CFCs were the main cause and had a clear replacement. Nevermind the solutions, I don't think we even agree on what the main problem is for climate change. Is it C02 emissions from cars? single-use plastics? methane? And for each one, there is no practical replacement yet.

  • There is a world of difference between the hole in the ozone layer and climate change. It was so much easier to deal with the ozone layer issue because a) it involved just one chemical (CFCs), b) the ozone layer hole has been caused entirely by human activity, and c) CFCs were never present in significant quantities on Earth before modern industrial civilization came into being. By contrast, climate change is so much more complex of a phenomenon/issue, and it's caused not only by fossil fuel emissions and other human-induced factors (e.g. the urban heat island; land use changes) but also - and arguably more so - by natural factors like the sun, oceans, cosmic rays, Earth rotational cycles, and volcanic eruptions. Wildfires, floods, severe storms, and the like would be happening anyway without fossil fuel emissions, and just look at the historical and geological records for more.

  • When we were kids, there was chocolate company which offered a scheme - "if you collect outer plastic packaging of our chocolates and send it to our po box, we will reward you with 1 bucks for every 20 piece of plastic wraps" It was printed with a slogan "we produce it so we take care of it". They would recycle the wraps. Thats what happened with ban of cfcs. The manufacturers of cfcs were targeted more, I think that's why it was possible to fix the main issue. So the those who produce these things should be questioned more than often.
