United Nations Says Earth's Ozone Layer Is Repairing (bbc.com)
An anonymous reader quotes a report from the BBC: The ozone layer, which protects us from ultraviolet light, looks to be successfully healing after gaping holes were discovered in the 1980s. The Northern Hemisphere could be fully fixed by the 2030s and Antarctica by the 2060s. A new United Nations report says it's an example of what global agreements can achieve. The ozone layer had been damaged by man-made chemicals called chlorofluorocarbons (CFCs). The chlorofluorocarbons (CFCs) effectively began eating away at the ozone. CFCs were found in things like spray cans, fridges, foam insulation and air conditioners. As a result, in 1985 a gaping hole in the ozone over the South Pole was discovered. An international agreement called the Montreal Protocol made sure that businesses came up with replacements for these damaging products. 180 countries signed up to it. In signing the protocol, those countries agreed to phase out chemicals like CFCs.
But we are still making SUVs??? How can this be???? Al said so.
... adds to global warming!

On its own, the ozone hole has slightly shielded Antarctica from the much larger effects of global warming â" it has heated up but not as much as it likely would without ozone depletion, said Ross Salawitch, a University of Maryland atmospheric scientist who co-authored the report.
So, now what? Do we keep rebuilding the ozone layer knowing that it will increase the effects of global warming? Or do we go back to CFCs, knowing that those actually cool the earth (which is what we want), but give seals and otters and stuff sunburns?
And that Expedition is still burning holes in the "o-zone" according to ladyboy BeauHD. Might I add BeauHD shall be eliminated due to his homoerotic tendencies.

You never miss it until it's gone.

If Trump did his thing and pulled out of the UN agreement on CFCs...... it would make zero difference.
Because no manufacturer would use CFC, the consumer backlash in the US would stop the product selling and they wouldn't be able to sell that product in the rest of the world. So they wouldn't make it and even try. Trump's word would not have any effect.
When he pulled out of the Paris Climate Accord, it had no effect on the US's efforts to cut its greenhouse gas emission. The efforts on solar and electric continued anyway. He failed to get his coal subsidy, and even if he attempts to drop mercury emission standards. Any coal fired power station would simply be sued for emitting mercury into the atmosphere.
These agreements, they are aspirational. They set a goal which is followed because it has mass agreement to be followed.
Y'know, when I'm gone, they'll talk about my books, my kid, all the amusement I provided my Chinese in-laws via my attempts to communicate in their language, my IT career, maybe even the restaurant I ran, if I live long enough to retire and start one...
But you? "He posted Nazi ASCII art to Slashdot. The End."
At least Eichmann got to brag about how he was leaping happily into the grave to join the millions he'd already put there. Evil, yes, but you can't deny he'd left his mark. You? You get nothin'.

... which is the only reason that I know about it.
I suppose a Lab Coat ha replaced the goofy beard and head dress these days.
Wasn't there already news about China still using CFC?

Unless CFC doesn't really have an impact on the ozone layer

Thanks Obama!
You say fag like it's a bad thing.
Meanwhile you will die alone, a kissless virgin, your fetid morbidly obese translucently pale neckbearded corpse found in a basement lair somewhere, in filthy underwear and not much else, surrounded by Nazi icons and imagery that you really never understood, and leaving behind you only an online echo of pointless hatred and misogyny. No one will come to your funeral, which will be held at the county coroners office, and no one will claim your ashes, in their plain clear plastic bag and plain white cardboard box, which will eventually be disposed of in whatever anonymous way they dispose of the remains of the unloved and unwanted. All because you decided to be a blackpilled asshole who would align himself with worthless fuckstains like neo-nazis. What a sad waste you are.
Indeed, and CFCs were also a lot easier to eliminate. They were far less fundamental than Carbon.
Indeed, before the fairly recent availability of cost effective solar, it looked impossible. All the rivers have been dammed. Nuclear has been damned. The only one available was wind.
But it looks like we will do it. Eliminate Carbon. If only because much of the world's population will be eliminated by the warming...
In May this year, reports emerged to warn of new, un-traced pollutants that were extending the damage to the ozone layer, particularly in the southern hemisphere.
See here.
Now, barely 5 months later, we have this very different perspective. Not being a climate scientist, I'm not sure how we can discern which of these two articles carries the most accurate reporting. (In that it seems unlikely that new damage observed in May could be healed this quickly).
I am a little concerned that the more recent of these two articles (carried in the BBC and linked in this slashdot piece) seems to make no reference of the concerns raised earlier this year. Very interested to know if anyone can shed light on this apparent disparity.
OK, I get it - Global Warming!
Lol. Your life is a stereotype.
they just found out the hole is getting way bigger than was previously estimated and now they're just hiding the truth from everyone, out of fear it would cause a global panic, riots and massive civil disobedience.

""We are only at a point where recovery may have started," he said, pointing to some areas of the ozone that haven't repaired."
So, no ... the ozone hole isn't fixing itself. In fact, if the report from April is correct, the ozone is getting thinner.
This is why I mistrust almost all science news articles except in actual science magazines.
The narrative here is that they want it to be fixing itself so humans can hug themselves over cooperation, therefore they are wish-casting it as a success.
There is no evidence the ozone hole is repairing and plenty of evidence to the contrary.
I remember this from back in the early 80's. By the mid 90's, they said that the hole had repaired itself. Within a few years, the hole opened back up and people realized that we were reacting to a natural and cyclical event.
Is this UN report an old report?
Because:
https://www.nytimes.com/2018/1...
What is unclear from the article is how much new CFCs are being released relative to pre-ban amounts.
Waterfox - a Firefox fork with legacy extension support, security updates and better privacy by default.
When it comes to replacing CFC's there's something to remember: there were alternatives that worked well and were readily available in an ostensibly cost effective manner.
A global agreement to curb CO2 production will be far harder to implement given the value & size of the markets that are the leading contributors to CO2 production. The CFC industry wasn't a trillion dollar international industry, globally employing many millions of people, or with pockets deep enough to lobby every government in the world simultaneously. Fossil fuel is.
The reduction of CFC use and the replenishment of our ozone layer is a great success story, but it doesn't mean that the same methods applied to other environmental problems will have the same scope of possible success.
and no one is worried about the fact that the hole is currently cooling the planet...holding back a little warming.
Oh well, still laughing at those reports last year decrying acid rain as if it was a new thing never discovered.
and what about the gellification of the great lakes?
Humanity is so screwed.
Ever notice how as soon as we started getting the "ozone hole" under control, all of a sudden, "global warming" was the problem? The globalists always need something to scare people into submission.
Good. When can we start cleaning our circuit boards with Freon again, and fuck lead-free solder
How do we know that the ozone hasn't always had a hole in it? when did the hole first appear?
Kyoto, and paris, are jokes. The fact that we allow nations to add more fossil fuel power plants is a disaster. Instead, ALL 'additions' should be killed. Replacement would be fine, but that is what is happening.
I prefer the "u" in honour as it seems to be missing these days.
...just this year it was reported that, while the ozone holes above the poles are shrinking, the ozone layer is *thinning* above urban areas: https://www.atmos-chem-phys.ne...
I am not a number - I am a free man!
ascii legacy is better than a chink family, imho
less shameful
Obama lowered the ocean levels just like he promised in his campaign speeches, so can we allow people to work at jobs again?
Thanks to China and India
Fortunately, it all turned out to be bunk science anyways.
CFCs were found in things like spray cans, fridges, foam insulation and air conditioners.
Factories and Spray cans, yes... the rest: pretty much no.
The hole in the Ozone layer wasn't caused by us having CFCs in refrigerators.... it was caused by CFC and Halon Emissions, or the Release of CFCs and Halons. Primarily from the emissions of industrial factories and facilities making the things, Halon gas Fire Suppression systems like those that used to be used in computing centers, and from Spray cans, yes.
Refrigeration equipment, on the other hand.... is designed to contain CFCs, not release them. It's counterproductive to emit the CFCs, because the equipment doesn't work after they leak out, so leaks get patched quickly, and refrigeration is not a significant source of CFC emission. R-12 Freon
is the most suitable refrigerant found, and any of the replacements resulted in equipment that won't work as reliably or efficiently ----
some of the latest replacements being used now to avoid CFC-like chemicals (While lining the pocketbooks of new chemical inventors)
are downright scary.... R1234yf ---- just what we need in the engine compartment of all our cars, a pressurized system with highly-Flammable refrigerant
that costs 100X as much by weight as the R134a HFC that some beancounters or lobbyists in the chemical industry who need more profits by forcing replacement with a newly patented magic formula deemed too CFC-like.
The ozone layer hole could be even smaller if we can get China to stop releasing them.
One of our competitors trademarked the term "hypothesis". From now on, we will call them "boneheaded ideas".
Is this suggesting to me that 'international collaboration' does work when government across the globe recognize a global problem? I'd certainly hope everyone comes to the same page for pollution and GHG...etc. Something to be hopeful on???
America got there first but now no one else is allowed to be like them. All you up and coming countries must not be allowed to develop as we did. Even if you only produce a fraction of our CO2, you just aren't allowed to be like us.
If you want to kill your way to a cleaner world million for million it's much more efficient to kill Americans.
Wipe out 300 million Americans to save 5 Million Kt of CO2.
300 million Chinese would only be 2.4
300 million Europeans 2.1
300 million Indians only 0.6
If the whole Earth had a vote, America would clearly draw the short straw...
Global nuclear electricity output grew 1 percent in 2017, as the world’s nuclear fleet generated 2,503 terawatt-hours (TWh) of electricity, according to the World Nuclear Industry Status Report 2018.
Take China out of the picture, however, and the reality looks starkly different: Global nuclear power generation would have declined for a third consecutive year, the report showed.
