Ozone Hole Smallest Since Records Began, Say Scientists

..."although this was due to weird weather conditions rather than human attempts to control CFCs."...

..."According to NASA and the US National Oceanic and Atmospheric Administration (NOAA) in Colorado this is the third time in the last 40 years that warm temperatures have limited ozone depletion.

Susan Strahan, an atmospheric scientist as NASA, said: 'It's a rare event that we're still trying to understand. If the warming hadn't happened, we'd likely be looking at a much more typical ozone hole.'"...

LOL what a joke!!

I remember when the Ozone hole was going to kill all of humanity? we were going to all die. The sun would burn people to a crisp.. blaw blaw blaw.. now its global warming and once people stop eating that Bullcrap, another issue will come to the forefront. These kids think the world will end in 10 yrs... can you imagine? what a joke. Parents should be ashamed of themselves for letting their child believe this crap.

I saw lately that now humans are contaminating the solar system!! we are causing weather issues on Jupiter!! earth microbes are somehow traveling thru the cosmos.. can't wait for the next huge volcano to erupt!! must be the surface temperature of the soil that is warming the magna causing it to boil over and erupt! Or how about a huge asteroid hit... we caused the asteroid to gravitate to earth because of all this extra CO2 in the atmosphere which caused more mass and therefore an increase of gravity.

Someone else who doesn't " believe everything you read". You, like I, try to fathom some sense from anything we read. I don't think there are very many of us out there anymore. At least that what it appears to be to me. Most parents (my opinion only) these days more often than not, rely on other sources for educating/informing their children. Even the education system can be flawed by teachers own personal opinions.

Everything read has to taken with a grain of salt. It isn't wrong to be pessimistic, or even disagree with what you read. After all, science is about data (and understanding it) and data can be skewed, omitted, supplemented, etc. to make any mathematical model work.

We'll just have to wait and see what happens, you know the old fashioned way.

Starts off with ". . .committed to stopping the devastating effects of the climate crisis on people and nature . . . "

De rigueur.

Something else to blame on global warming....

So all the hoops we had to jump through to comply with the Montreal Protocol evidently had no effect....what a surprise...but a lot of people got rich playing the game....and the rest of us had to pay...Now they want to up the game with global warming...These are nothing but money making scams...

That was an interesting article, but there appeared to be something missing. There is no mention about the UV intensity reaching the earth's surface.

Since ozone is responsible for blocking some portion of the UV-A and UV-B rays, I would expect to see normalized UV radiation either increasing or staying stable given decreasing or stable ozone . Increased ozone should reasonably expected to decrease the UV radiation reaching the surface. Since the sun's output can vary, we would also need a UV sensor outside our atmosphere to act as a normalization factor.

I couldn't find any historical information over this time period. Plenty of UV maps for a month or year, but not historical averages over many years.

The only study I could find is linked below, published in a book... as you can see from the graph posted the amount of UV radiation varies according to incidence angle, which constantly varies...the difference that even a 20% reduction in ozone seems to be rather minimal...I would like to see a historic study of UV strength at different locations, if anybody runs across one that is legitimate, feel free to post it here....but the effects seem to be overblown as usual....

..."Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions."...

What are "natural emissions"?

Natural emissions of ozone depleting chemicals are primarily volcanoes.

https://www.cbsnews.com/news/blazing-world-record-strongest-uv-rays-measured-in-south-america/

Interesting....

..."The researchers think seasonal thunderstorms over the Andes and fires burning in the Amazon could have depleted protective ozone, along with an atmospheric train of ozone-depleting chemicals streaming north from Antarctica. A large solar flare from the sun two weeks before the spike also could have affected atmospheric chemistry and destroyed some the planet's protective ozone layer."...

Maybe it all comes down to solar flares and volcanoes being the main causes...

...."In 2010, a total ban on CFCs was put in place, but certain loopholes still exist in the Montreal Protocol that allow trace amounts of the chemicals to be used in the production of certain products, including some types of insecticides and solvents used to clean electronic equipment. [Top 10 Ways to Destroy Earth]

Now, researchers based at the University of East Anglia in the United Kingdom have calculated that these loopholes — previously thought to be relatively insignificant — have actually allowed more than 74,000 metric tons (about 82,000 tons) of three previously unknown CFCs, and one related compound known as an HCFC, to be released into the atmosphere. While this quantity is far smaller than peak CFC emissions in the 1980s, it is still a significant quantity that could slow the recovery of the ozone hole, the team reports today (March 9) in the journal Nature Geoscience."...

Now I am curious as to how seasonal thunderstorms can deplete the ozone layer because any electrical discharge generates ozone and lets face it thunderstorms do generate a lot of electrical discharges so there should be more ozone. With all the insulators on power lines generating corona, ozone, then we should have more ozone. Best we put leaky insulators on our power lines and generate more ozone

This sounds like the rain forest syndrome where the absorption of CO2 is equaled by the decay of the carbon matter from the dead plant life and makes no difference at all?

Sounds like the government what you are given by us, so shall we take away by stealth, but don't worry we know what we are doing!

Thanks for the article.

I took this away from it, "It's not a sign that atmospheric ozone is suddenly on a fast track to recovery."

This is what I took away....

..."Susan Strahan, an atmospheric scientist as NASA, said: "It's a rare event that we're still trying to understand. If the warming hadn't happened, we'd likely be looking at a much more typical ozone hole.""...

..."We thought the hole would close and the problem would solve itself. But a new study, surveying a part of the ozone layer that hadn't been examined before, shows that the overall problem hasn't improved in 20 years."...

From the book titled...

Stratospheric Ozone Reduction, Solar Ultraviolet Radiation and Plant Life

..."UV Light Reduces Fungal Growth. UV light can alter the DNA of all organisms – plants, humans, animals, and even fungi. Organisms exposed to UV light on a regular basis develop mechanisms for preventing and treating DNA damage, such as “sunscreens” and DNA repair enzymes.May 8, 2018"....

http://ursalighting.com/effect-uv-light-plants/

So it seems there was a total of 4% ozone layer reduction....probably not even a measurable difference over the course of a year...It seems the reduction of nearly 90% of ozone depleting chemicals would have made some difference....that is if the two were connected....? Maybe it's all just total BS....

The first indications in the record of an ozone layer hole were surface UV radiation measurements of a French arctic exploration team in 1914. The takeaway is that the ozone hole is a natural phenomenon resulting from the earth's magnetic flux lines and solar wind.

The actual depletion of atmospheric ozone by CFCs has yet to be demonstrated in the atmosphere and remains a postulated theory based on extension of a laboratory experiment that may or my not have fully represented atmospheric conditions.

I've always been amazed at how a good media spin can cover gross incompetence.

He selected his team based on how well they got along rather than whether they actually knew what they were doing.

What I took away from the article.

1. Climate change is a British issue.

2. Either NASA supports friends of the earth or friends of the earth support NASA.

3. Every story sounds like an episode of zombie apocalypse.

Sarcastically following-on line item number 3 of Post # 13:

No, no, no! You don't understand! The world is not going to end due to ozone-hole political-zombie apocalypse!

Current projections have the Ozone Hole completely ''healing'' by 50-some years from now.

Every correct-thinking, self-respecting, enviro-activist knows that the World will end first due to the outdoor-air-conditioning-zombie apocalypse... Sheesh...

Get on the ''correct'' side quick, and avoid the shame of being on the ''wrong'' side, while you still can...

Things are better than they ever have been but it can't be from anything being done right, it has to be from something else. Let's think, what could it be from?
