World News
A community for discussing events around the World
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.
-
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 OCTOBER 19 2025
-
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.

The vaporized materials themselves are a problem. When we're building these mega-constellations, we're putting some real mass up there. We're introducing all sorts of exotic materials into the stratosphere that would not naturally occur there at those concentrations. And remember, this is a very sensitive environment. The actual volume of CFCs we introduced into the stratosphere wasn't that large. The volume of all our AC refrigerant and hair spray cans was nothing compared to the atmosphere. We may actually not be that far from the sheer volume of satellites affecting the ozone layer as they decay.
The stratosphere is an environment like any other. It has a finite ability to absorb and process any form of pollution without noticeable and significant effects. I'm not qualified enough to estimate the number of satellite reentries to damage the ozone layer or to have other deleterious effects, but at least from that study featured in that video, we may not be far off. The story of civilization has been repeatedly realizing that what we once considered infinite dumping grounds were anything but. And the stratosphere is no different.
Edit: may have misinterpreted parent comment and went off on a wild tangent.
We would be pretty lucky if it impacted something like the ozone layer in a noticeable way as that's something that can be seen and could be acted on and repaired as we've done before.
It's the effects that we don't know that are probably going to be the bigger problem.

Ah, nothing like the taste of fresh satellite in the morning!
Nothing quite like that aluminum oxide! So refreshing!
What does that have to do with orbits and reentry angle?
That's a good question!
I think you meant to respond a couple comments up the chain.
