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. 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.

Can we get lucky just this once and this new ocean circulation cancels out global warming?
“Early reports indicate that a vortex has emerged as a result of the reversal which is drawing in carbon dioxide, microplastics, PFAS, and, inexplicably, members of the Trump administration.”
Damn keep going I almost jizzed
Nope.
I had to look up that last part, as it seemed counter-intuitive, but apparently deep ocean water bottoms out at 4 degrees C.
4° is as dense as water gets. After that it starts expanding as it turns into ice. Which is how ice floats. It's one of those miracles of nature. If ice sank things would be very different.
Can you expand on that or ELI5?
As water starts to freeze the molecules start to rearrange thrmselves from a free flowing random motion into a crystal lattice. As it does this the molecules push each other a little further apart and lock into place, but because they are further apart they now take up more 'space' and as such they are less dense. The water wround them now has more water molecules for the same volume that the ice does and that means the water sinks (as its heavier) and ice rises.
To really ELI5: Imagine water is like a crowd of people balanced on a REALLY giant see-saw, everybody is really squished together and when they get cold they decide to put their arms out wide and grab hands with the people around them, but making small circles with the other people also grabbing hands until there is a big group of people made of little rings of people arms out holding hands. Now imagine that the people with their arms out have to spead out and some fall off the edge of the see-saw. Now there are less people on one side of the see-saw and because the other side is heavier, that side drops and the people with their arms out rises.
If the crystalline structure of water did not expand from it's liquid phase (thus lowering it's density) when it freezes, then ice would not float. Ice would sink trapping everything below it. It's theorized that this little fact means life likely couldn't exist if ice didn't behave this way.
Right, but I still wouldn't call water that is 4 degrees C as warm. How is deep water warm?
I'm not going to claim to fully understand the nuances, but the sea ice will melt at about -2C and glacial melt will deposit ~1C water into the system. If the deep water is steady at 3C or 4C, sending it up could accelerate melting of both.
Thank you... I'm an idiot and wasn't thinking about the Southern Ocean as in 'The' Southern Ocean... instead I was thinking about it in terms of the oceans in the south (as in, not necessarily glacial). But yes, now I get it and understand. It probably would have helped if I had opened the link to start with.
That was my physics teacher.
"So materials shrink as they get colder."
"Ma'am, doesn't ice expand?"
"We don't talk about that."
Ice doesn't expand. Ice as a solid shrinks when getting colder. H2O expands during phase transformation from liquid to solid.
Imagine.. this is the earth's response. A defensive reaction to a climate imbalance. Solving all climate issues. Would have a crazy new respect for the planet.
Planet is already on like a 5000 scale for me. This would add another zero, maybe 2.
Earth don't give a fuck. It's been hot. It's been cold. It's been filled with poisonous gasses. It might be any of those things again. Earth could care less about us and is probably about to show us where we stand.
Earth is not even fucking sentient, it’s not even fucking alive. That’s how much it doesn’t give a fuck about anything.
Humans, with all our intelligence, can only dream of giving less fuck that Earth. What a legend.
Ahhahahaha, no, just the opposite
