“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
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.
I also heard that we fixed it, but it was in the southern hemisphere before too.
definitly south was an issue I grew up with, we got warned about all the skin cancer this would cause
I thought we fixed this
inb4 this becomes the core argument for not doing anything to fix it again
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 😭
Tbh, I’m rooting for team Earth. Fuck humanity.
Definitely ready to enter Valhalla, all shiny and chrome. Now, where did I put my spray can?
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.
Sorry to break it to you, we stopped using CFCs because a cheaper alternative came along. That it happened to be less suicidal was a happy coincidence.
Cheaper to manufacture? Yes. Cheaper for the end user? It depends. See: Ventolin HFA.
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.
I'm sitting here in the southern hemisphere wondering at what point we'll no longer be be able to go outside unprotected.
imagine if the only food available was grown indoors
I was hoping when the world got too hot then Antarctica would become livable, but I might need to rethink my retirement plans.
Antarctica is still the expected mass migration target for the 23rd century, ozone hole or not.
I don't know if it's true or not, but I've read that when places become more temperate because of climate change, they're still not very livable because there's no soil capable of supporting crops.
It takes decades for the soil to get invaded by bacteria, grasses, shrubs, trees... but eventually they will get there. With a little human help, it can get done even faster.
The warming process is blazing fast on geological scales, but for example sea levels are not expected to reach the top of the Statue of Liberty for at least another 500 years, so on a human scale it's more than enough time to build whole cities, generate fertile top soil, or to organize scuba trips to the 9/11 memorial and put warning signs at sub tunnel entrances.
I'm planning to move to Sweden when I retire. Of course, that will be a tropical climate by then.
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.
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.
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.
That's gotta be, like, the absolute worst place it could be
I don't think anywhere is good but I would guess that being farther from the equator is better since there is less direct sunlight. I could be wrong though.
Well, that's not great
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.....
