The massive hole in the Ozone layer that opened up decades ago in Antartica is finally fully closed

 

Scientists made the announcement recently, one of few positive pieces of news regarding Earths Climate and Environemnt

Leave it to GGD to turn an antartica ozone layer news thread into a sex joke :toofunny:

Hey, a little it's some good news :vegas:

I'll take it :vegas:

I remember first hearing about it when i was a kid

 

Back then ozone depletion was still a huge worry, more than global warming id say

Whats the cause of it? Did it heal on it's  own?

It was caused by a chemical compound called CFC that used to be emitted by some products like old fridges, by eliminating its emission the layer was able to recover 

If you see me posting like crazy, I'm either bored or procrastinating.

Damage to the ozone can fluctuate based on varying temperatures which alter chemical reactions and so does atmosphere flows

 

But as a general rule what was damaging it was CFC chemicals because when the chlorine particles broke off the CFCs they reacted with O3 (ozone, 3 oxygen atoms) in a way that broke the oxygen molecule bonds apart hence damaging and depleating the layer slowly. Temperatures affect the rate of reaction which is why some parts of the globe were more prone to ozone depletion than others and why the size of holes would even fluctuate throughout the seasons of the year.

 

CFCs were banned in most Countries after it was discovered how harmful they are to the ozone layer but it took decades for healing to start

 

The Ozone Hole in Antartica was by far the largest ever and its been slowly recovering since late 1990s so it took over 20 years to fully close

Tho not fully. The Ozone layer is still not back to pre industrial levels and if im not mistaken a few Countries still havent banned CFC use

 

But while the problem hasnt fully gone away it definitely is not one of the more serious pressing issues it once was

is this the one that affected South America? bc I remember in Chile there were days you were not allowed/highly unrecommended to even go outside/into the sunlight bc pure UV rays. On that note, I remember there were certain days certain license plates weren't allowed to drive (or something close), to lower emissions. Awesome that it's closed.
