Ozone hole over Antarctica grows to one of the largest on record, scientists say
Ozone hole over Antarctica grows to one of the largest on record, scientists say
The annual ozone hole that forms over Antarctica has ballooned to near-record size, scientists say.
“Last month, the U.S. Environmental Protection Agency delayed plans to tighten ozone pollution standards until after the 2024 presidential election.”
Huzzah! More political BS playing games with the planet and all our lives.
We’re so doomed. A coworker asked if I was interested in kids and I said I would feel bad bringing a child into this mess.
Ground level ozone and the ozone hole are two different issues. The delayed EPA regulations would be limiting ozone produced. At ground level, ozone has various health hazards. The ozone hole is from ozone depleting substances reaching high altitude in the environment and destroying naturally occurring ozone. That high elevation ozone blocks UV light from the sun, and is protective for those of us who dislike skin cancer it what not.
That's exactly why I got a vasectomy. If it really comes down to it adopting is the better choice since those kids are already stuck existing so might as well just try to make the world slight less miserable for them
This has nothing to do with the ozone layer in the stratosphere, but pollution in cities and industrial areas.
"interested in kids" I think they mighta meant something else O.O
Honestly, it just seems like this shit'll never stop and no one gives a fuck in Washington. Everyone's too busy playing politics
That quote is technically true, but based on the article they link, it doesn't sound to me like the delay and the election are related.
Except the second article does mention ‘it avoids a fight during an election yeah with industry and republicans’ but then later looks like they are trying to say that’s not at all why and want to take time. I don’t know, sorta seems like the election played a part in the decision
Ah yes, USA defaultism at its finest. Like you don't have any other countries working on it...
Okay, like china? India? Calm down. The US has a huge chunk of the co2 amount so it’s kind of important. Plus the article talks about it?
Well, zero chance of House Republicans even letting it come to a vote.
It blows my mind seeing people with little kids. Like, WTF is wrong with them?
Well that's a throwback. Not sure I care for this particular reboot of my childhood media.
We stopped using hairspray and everything :(
All those tasty cfcs
🏌️
Ah shit, here we go again
Ikr I thought we fixed this. I also thought it was in the northern hemisphere.
It's the 90s again, everyone stop using aerosol!
If girls start gluing their bangs with hairspray again I am done. They're already bringing back the abomination that was mom jeans ffs enough is enough! The bangs and damaged hairlines in another generation of women is going too far. Half of us don't even have eyebrows anymore let the 80s die 😭
Dang, what am I going to do with all this AquaNet ive got?
Is stepson aerosol like knock off store brand aerosol? It's it also red headed?
Tbh, I’m rooting for team Earth. Fuck humanity.
Permanently Deleted
At this point i would root for a return of cyano bacterian empire
Fuck. I thought we fixed this.
Me too. I've been carrying it around in my head as "the time we listened to scientists, and almost everyone worked together on some short term pain for worldwide long term gain". I was even hoping we might do something like that again.
There is some speculation that the unusual behavior of the ozone layer in 2023 is a result of the Tongan underwater volcano eruption in January 2022.
The immense amount of water vapor that was injected into the atmosphere likely just started reaching the south polar region after the end of the 2022 ozone hole, Antje said.
The water vapor could have led to a heightened formation of polar stratospheric clouds, allowing chlorofluorocarbons to react and accelerate ozone depletion.
Was literally just thinking about it this morning. Mere hours ago. Not even joking. This sucks.
The last paragraph is completely irrelevant, as it has nothing to do with the ozone layer. You do not want ozone in the troposphere, but you do want it in the stratosphere.
But who hadnt it happen yet? It is saturday, you have yet to drink your coffee, but your dog needs a walk so you go out, take a wrong turn and BAM! you are in the stratosphere breathing Ozone!
The only Ozone I want to end up in is the Dragostea Din Tei ozone.
I'm sitting here in the southern hemisphere wondering at what point we'll no longer be be able to go outside unprotected.
I think that point was like 1990. After that there's been enough excess UV that you should have been using sunscreen basically all the time.
Slip, slop, slap. I think that goes without saying.
More like Stop, Drop , and Cover this time.
Lol oh man I remember back in the 90s before everyone gave up when we were trying to actually shrink that thing
We shrunk it and it was as good as done once everyone stopped using those gases.
Over the last few years satellites have picked up greatly increasing emissions of them from China. Hence it’s opening up again.
Oh and before any hexchud wants to say this is fake news or whatever:
We show that emissions from eastern mainland China are 7.0 ± 3.0 (±1 standard deviation) gigagrams per year higher in 2014–2017 than in 2008–2012, and that the increase in emissions arises primarily around the northeastern provinces of Shandong and Hebei. This increase accounts for a substantial fraction (at least 40 to 60 per cent) of the global rise in CFC-11 emissions. We find no evidence for a significant increase in CFC-11 emissions from any other eastern Asian countries or other regions of the world where there are available data for the detection of regional emissions.
I'm curious what the actual source is. CFCs are practically obsolete and there is no point in producing them when HCFCs are cheap and hydrocarbon refrigerants are practically free. You'd think China would be using R290 and R600a in any new builds since they're so cost sensitive. You can even straight swap R290 to replace R22 if they want to use old compressors or something.
I'm wondering if this is a pile of old refrigeration equipment that was dumped and shipped to China, and is now being scrapped in an irresponsible manner or just corroding and leaking. I'm sure there's loads of R11/12/22 out there, as R12 refrigerators are still regularly dropped off at our local scrap pile here in Canada.
Thanks for posting the finding links. I hadn’t heard this before and it gives me a good place to start reading. Crazy that we know this is bad for the earth but we keep doing it. I wrote that sentence and mid way through realized how naive it sounds 😖
We actually did fix it. The whole world came together and banned those gases. It was a masterpiece of global cooperation.
Unfortunately they've started being detected again in growing quantities in recent years.
Last I heard those emissions had starting going back down. Was there anything new on that front since then?
My theory is old vehicles and machinery are gonna release gas
So it seems that this hole in the ozone is a yearly occurrence. CFCs left over from the old days get caught in a yearly wind and poke a hole above antartica. They're not really sure why it's bigger or why it happened earlier than previous years, but they believe it has something to do with an underwater volcano eruption from last year. I think that's the jist of the article.
Man... people really don't like reading articles so much as they like speculating about headlines.
And, while I feel like I should copy/paste the important bits, isn't it just as easy for people to click the link and read the whole two minute read? Should I paste the full article and bold the important bits? Why should I have to do the work for people who honestly do not care about more than comment karma.
I appreciate the article OP. I wasn't aware of the nature of the ozone hole. I also found the linked article that was published in January to be insightful.
Reading it takes all the fun out of the guessing game. /s
To be fair, some of the confusion here is from reading the article, or at least skipping to the end.
Well, that's not great
But... I recycle.
Do it but harder
I pocket mulch.
Geez....and here i was thinking "I'm doing my part in helping the environment" by using public transport instead of driving, and using paper straws.....
Those damn private planes
We in Michigan would love that thing to mosey on by come January...
It doesn't make it warmer, it just gives you cancer.
