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.

@Albert Abramson I believe they found this hole in the late 70's, then they freaked out and said we have to close it up by making cfc's the boogie man. then politicians said I'll back this plan for easy votes, the media milked it till the public stopped watching.......now the hole is still there and I doubt that we even know how long it's been there. now on to the next vote and ratings getter.

Difference is, that in question of ozone, there was not so many corporations who would beneficed to avoid changes. It was easy to "sacrifice" few, in benefic of all others. And also, answer was easy to find - very little really changed. But in climate change question, there is so massive about of corporations, who's business will be ruined, it we take actions. In capitalism, people do not have any political power, corporations have. People do not change minds of politicians, corporations do. And so many corporations are defending old ways, instead of change. They spend lot of money and effort to make sure, that we do not act against the climate change. And they are winning - while we, people, are losing.

Trying to piggy back global warming after the ozone layer issue is dishonest and political. It is a much more complex issue, with many variables, harder to solve, and the images of the natural catastrophes cannot be linked to it without a doubt. The video stopped being serious when they showed Greta Thunberg. Trying to hold responsible the citizens of western countries is a lie. The issues comes much more from industries and China.

I don't believe that there was anything that humanity did to create the hole or to heal the hole in the ozone layer it was a natural phenomena, it's like saying that the small amount of CO2 gas that is produced by humanity witch is only .30% of.4% of the atmosphere not enough to make any difference to the climate yes there is climate change but you would have to live for at least 1000 years before you actually saw any change what we have is a change in the weather not the climate.

Important footnote: the scientists who discovered the causes of ozone depletion nearly lost the battle. Luck was on our side. First, we had scientists like Susan Solomon and Sherwood Rowland. They were highly articulate and personally equipped to deal with the political and personal threats from promoting their findings. Second, the chemical industry wasn't very organized (nor were they prepared) for the serial warnings and predictions. Third, citizens were surprised - news media gave accurate reports - and politicians rose and answered the call. You'd think that we'd do the same with carbon/global warming. As Dr. Solomon indicated, global warming is personal, perceptible, and plenty of practical solutions are on hand. But now we have to deal with a new "P" in the mix: global warming has become partisan.

Further, no ecosystem or species was ever shown to be seriously harmed by ozone depletion. This is true even in Antarctica, where the largest seasonal ozone losses, the so-called Antarctic ozone hole, occur annually. Also forgotten is a long list of truly ridiculous claims, such as the one from Al Gore's 1992 book "Earth in the Balance"that, thanks to the Antarctic ozone hole, "hunters now report finding blind rabbits; fisherman catch blind salmon."
sam1953 Vor 16 Stunden
A few things you never hear about the ozone layer. It takes only one day of a volcanic eruption to put as much CFC into the stratosphere as the entire human population has put of its own CFCs. CFCs are heavier than air, so it is almost impossible for them to get pushed up into the stratosphere on their own. Historical studies of the ozone layer show that it has always varied in thickness naturally. Be careful what you believe.

Public perception is the problem. Can eliminate climate change in one year: nuclear power plants. Gas, oil, and coal plants can be gone in just one year with nuclear. Change over to an all electric grid. Nuclear waste is very minimal and we already have an entire compound built to store it safely in NV. We already have a practical solution that we can implement, we just don't do it.

I remember the "Ozone" hoax. It was introduced as replacement of the "nuclear holocaust" at the end of the Cold War. It had a double purpose: to keep the sensation of imminent doom and to replace CFC, whose patent had expired. Nobody bothered much about it, once the CFC was replaced, they dropped it and began other campaigns to frighten the population, like anthropomorphic induced climate change and global pandemics.

If anyone thinks climate change isn't a real thing, they need to get their heads out of the sand. Look at what's happening in Denver, Colorado and in Canada. At this time of year there should be no part of Canada getting 7" of rain in a single system or so, or ever. Not since the late 1800's has Denver gone this long without any measurable snow, today being December 1st. Times in the western half of the country are WAY ABOVE average.
