Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

MODERATORS
Lots of doom and gloom in the comments here. As the article describes, the hole in the ozone layer varies in size over time. It is slowly recovering, but the annual variability means it sometimes is larger than before.
And
Sounds like something global warming can make worse.
Isn't the northern hemisphere jet stream struggling due to decreasing temperature differences, since the poles are warming faster? Which then causes weather to change less, making things more extreme?
Gulf Stream, not jet stream. https://www.bbc.com/news/science-environment-66289494
so you don't think the increase in methane is gonna effect this?
I dunno about you, but 'lots of doom and gloom' sells short of utterly fucking shocking temp rises in the ocean, the slowing of the gulf stream and the heat-stroke of a winter the southern hemisphere just endured.
meteorologist Brian McNoldy of the University of Miami called global air and ocean temperature trends "bonkers," stating: "People who look at this stuff routinely can't believe their eyes. Something very weird is happening." https://www.axios.com/2023/06/13/climate-extremes-warming-charts-concerns
I'm not trying to fear-monger but I think we'd all be better off frankly recognizing the shit isn't going to hit the fan, it's hitting it rapidly and the backblast is beginning to impact. It's not doom-and-gloom if it's actual reality people are trying to live through.
The hole was set to be normal by now.
Where did you hear that? CFCs can linger in the atmosphere for 50-100 years, so recovery is a slow process. It took more than a decade after the Montreal Protocol went into effect before the hole in the ozone layer stopped growing. Additionally, different parts of the ozone layer will recover at different rates:
