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.

In the 1980s, scientists began to realize that ozone-depleting chemicals, such as chlorofluorocarbon (CFCs), were creating a thin spot—a hole—in the ozone layer over Antarctica. Through an international effort to decrease the use of CFCs, the ozone layer is starting to mend, and scientists believe it should mostly recover by the middle of the 21st century. This series of satellite images shows the ozone hole on the day of its maximum depth from 1979 through 2018.

This molecule is called ozone. The ozone molecules form a layer around the earth called the ozone layer. This layer absorbs the sun's harmful ultraviolet radiation and thus, protects us. But a time came, when the production of human-made chemicals like chlorofluorocarbons or CFCs increased a lot. These CFCs began to break more and more and more oxygen molecules, thus thinning or depleting the ozone layer. This depleting ozone layer is termed as ozone hole. However, now a days due to awareness, the production of CFCs has reduced to a significant amount. As a result, the ozone layer is slowly but surely getting replenished.

Antarctic: 2021’s Massive Ozone Hole Finally Closes

ANTARCTICA — A huge hole in Earth’s protective ozone layer opened up a few weeks ago, exposing humans to dangerous levels of the sun’s ultraviolet radiation. Here are the details: New Scientist reports that one of the largest holes to ever form in Earth’s protective ozone layer is finally closing. The NASA Earth Observatory reported that the 2021 Antarctic ozone hole reached its maximum size on October 7 and ranks as the 13th largest since 1979, exposing an area bigger than Antarctica. 2020 also saw a similarly oversized hole form for the same reasons, when a colder than usual winter in the southern hemisphere fed a deep and larger than average hole that persisted for a longer period than usual. The hole is actually the thinning of the ozone layer in the stratosphere above Antarctica. Chemically active forms of chlorine and bromine — derived from human-made compounds — are released into the stratosphere during reactions on high-altitude polar clouds. The reactive chlorine and bromine then spark ozone-destroying reactions when sunlight hits the Antarctic at the end of its winter. The hole would often force southern countries like New Zealand to issue ultraviolet radiation warnings in the middle of their summer months. Scientists predicted that the hole would finally close last week. Despite the surprisingly big size of the hole in 2020 and 2021, scientists still believe that the hole will finally stop forming by the middle of this century.

Ozone layer is our protective shield it's located in Earth’s stratosphere. It absorbs most of the UV radiations that are coming directly from the sun. In the absence of ozone layer it would be impossible for life to survive on Earth. As UV radiations would cause diseases like Cancer. In the past, use of CFCs damaged the ozone layer and made a life threatening hole in it. But in 1987, Montreal Protocol treaty was signed and use of CFC's was banned by the world. Recent data shows that last year, Antarctic ozone hole hit its smallest peak since 1982. And ozone layer might recover fully one day. Due To Lockdown, Earth is Healing!

For more information: 🤍 The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The size of this year’s hole was 24.1 million square kilometers (9.3 million square miles) — an area roughly the size of North America. With the increased atmospheric chlorine levels present since the 1980s, the Antarctic ozone hole forms and expands during the Southern Hemisphere spring (August and September). The ozone layer helps shield life on Earth from potentially harmful ultraviolet radiation that can cause skin cancer and damage plants. The Montreal Protocol agreement beginning in 1987 regulated ozone depleting substances, such as chlorine-containing chlorofluorocarbons and bromine-containing halons. The 2014 level of these substances over Antarctica has declined about 9 percent below the record maximum in 2000. “Year-to-year weather variability significantly impacts Antarctica ozone because warmer stratospheric temperatures can reduce ozone depletion,” said Paul A. Newman, chief scientist for atmospheres at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Scientists are working to determine if the ozone hole trend over the last decade is a result of temperature increases or chorine declines. An increase of stratospheric temperature over Antarctica would decrease the ozone hole’s area. This video is public domain and can be downloaded at: 🤍 Like our videos?

The Ozone Scam

At the top of a warm dry cycle, you get scams and fraud. The current man-made global warming scam is one of them. But it wasn’t the first. Remember ozone? Back in the 1980s, there was a skin cancer scare that was simply based on a theory. The theory was that Freon, a substance used in refrigeration and aerosol cans, could break up the ozone layer in the stratosphere. Now, this “theory” has never been proven and the science says that it’s unlikely to ever to be proven, but politicians got on board and we banned the substance in the Montreal Protocol agreement in 1987. Lo and behold, when you look a little deeper, you find that this all happened at the exact time when DuPont was losing its patent on Freon, meaning that anyone would now be able to manufacture and use it. They’d lose their monopoly. But let’s get back to that science. The stratosphere is a layer around the Earth about 20-50 km above the ground. That’s where you find ozone being created. Ozone is formed when sunlight (or ultraviolet rays) meet oxygen molecules. The UV rays in sunlight turn oxygen (two oxygen atoms) into ozone (three oxygen atoms). But ozone is very unstable and when introduced to chlorine, breaks down into single oxygen atoms. These two processes happen over and over and over again way up there in the stratosphere. Freon contains chlorine. And that’s the about the only connection between Freon and ozone. Because Freon molecules are over four times heavier than oxygen. So there’s no way they’re ever going to get into the stratosphere. It would be like putting a brick in a swimming pool. The brick isn’t going to float to the top. There are two zones with reduced ozone at the top of the atmosphere—over the North and South poles. The area over the South pole is the larger of the two. The idea is that Freon somehow not only floated to the top but found its way to the poles and did its nasty work there. Now, the real reason there isn’t much ozone around the poles is that they’re the two areas on Earth that get the least sunlight. In winter, they’re dark 24 hours a day for six months. Freon can’t form without sunlight. And ozone levels haven’t changed since we found out about them. What’s more, chlorine, which is the real culprit in breaking down ozone exists in huge quantities in the atmosphere from natural sources. It evaporates from sea water and gets to the stratosphere through thunderstorms, hurricanes, and the like. Volcanoes pump out millions of tons of chlorine. Forest fires add millions more tons to the atmosphere. And here’s the paltry amount that could get added from all the Freon in cans, if we could somehow get Freon to travel 50 kilometers and break down into its parts, which it doesn’t like to do. So, what’s the real reason it was banned? Well, let’s go back to Dupont and their patent. It was about to end and Freon, which cost about 50 cents per pound to manufacture, would have been available for all their competitors to use. So, while they supported this crazy science and pushed for a ban on Freon, they got busy and created an alternative series of products that are up to 20 times more expensive. And they have the patent on these new products. Of course governments get their fair share through taxes. It was as win-win situation! So, I’ll let you be the judge as to how much truth there is to the Freon ban. In any event, the result of it has cost the public billions of dollars based on science that makes no sense. This is the kind of fraud I see all over the place, and it’s usually a bi product of a warm dry cycle, leading to a major revolution. So, it’s not like it won’t happen again …

02.11.2018

Every year, the ozone hole over Antarctica reaches an annual maximum extent during southern winter. The depletion of ozone by chlorofluorocarbons (CFCs) happens faster at colder temperatures and slows down as temperatures warm, so each October, the ozone layer begins to heal again for the year. Scientists from NASA and NOAA work together to track the ozone layer throughout the year and determine when the hole reaches its annual maximum extent. This year, the South Pole region of Antarctica was slightly colder than the previous few years, so the ozone hole grew larger. However, scientists from NASA have developed models to predict what the ozone layer would have looked like without the Montreal Protocol, which banned the release of CFCs. Although the 2018 hole was slightly larger than that of 2017 or 2016, it was still much smaller than it would have been without the Montreal Protocol.

Learn some more about the hole in the ozone, as a part of environmental chemistry. The hole in the ozone layer has become thinner, mainly due to CFC’s. CFCs are inert stable molecules and were once the wonder chemical. They were completely harmless to animals, and were used in many household products. The problem with CFCs is that they are so inert that they do not get washed out in rain or broken down in the troposphere, so they diffuse up into the stratosphere. Here they are broken down by UV light, and bond with the free oxygen. This then prevents the free oxygen from reforming ozone. Hence CFCs have caused the break down of Ozone. So the ozone-oxygen cycle was being destroyed and the ozone layer was thinning all over the world. Because of the special weather conditions around the South Pole, almost all the ozone became depleted there, forming the hole, once the sun returned in spring. In 1987, all nations of the world banned the production and use of CFCs. The ozone layer is naturally reforming, and so return to its original levels in 50 to 100 years. The hole in the ozone layer allows harmful UV radiation to reach ground level, which can cause skin cancer. It does not however let in heat and cause global warming.

In the upper layers of the atmosphere, three oxygen atoms come together with the help of the sunlight to form an ozone molecule. These ozone molecules form the ozone blanket or the ozone layer, which keeps life on earth safe from harm. But is there a hole in this ozone layer? If so, will the sun’s harmful radiation just reach us and cause us direct harm? In this video, we answer all of these questions for you.

A mysterious spike in ozone destroying emissions, CFC-11, has finally been located to 2 provinces in China. But what is CFC-11 and what happens now? The Ozone Layer Was Doomed Until a Handful of Scientists Stood Up to Power - 🤍 Read More: Stratospheric Ozone - Monitoring and Research in NOAA 🤍 “Ozone thus plays a key role in the temperature structure of the Earth's atmosphere. Without the filtering action of the ozone layer, more of the Sun's UV-B radiation would penetrate the atmosphere and would reach the Earth's surface.” Increase in CFC-11 emissions from eastern China based on atmospheric observations 🤍 “A recently reported slowdown in the decline of the atmospheric concentration of CFC-11 after 2012, however, suggests that global emissions have increased. A concurrent increase in CFC-11 emissions from eastern Asia contributes to the global emission increase, but the location and magnitude of this regional source are unknown.” Montreal Protocol on Substances that Deplete the Ozone Layer 🤍 “The Montreal Protocol on Substances that Deplete the Ozone Layer (the Montreal Protocol) is an international agreement made in 1987. It was designed to stop the production and import of ozone depleting substances and reduce their concentration in the atmosphere to help protect the earth's ozone layer.” Elements is more than just a science show.
