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.

The carrington event knocked out telegraphs all over the world in the 1800s.
That’s the most powerful geomagnetic storm on record. It induced so much current in the telegraph wires that they literally melted.
In the 1800s that wasn’t a huge deal. But if it happened today, billions of dollars of electrical infrastructure could be rendered useless, and stockpiles of replacements are already non existent. It would take years to recover.
But this is not that strong of a storm, so I doubt it’ll do anything but cause some pretty lights and maybe ground a few flights due to communications issues.
And I’m sure any affected areas and satellites will be shutdown for that period to reduce any operational risk.
So less planes falling and more planes delayed.
Same for network communications as items are routed around certain areas or via some methods like fiber vs others.
Planes wouldn't just fall out of the sky anyways lmao. Even if planes lost communications completely they are still operational flying machines. It would just be very difficult to coordinate planes landing at that point. I don't know about the protocols, but I'm sure there exist failsafes to coordinate air traffic in the event of radio communication loss.
It would be a bit more serious than a loss of communication. The electronics in the plane would be completely melted. Including the ones responsible for controlling the plane.
Airplanes are designed to withstand the current, voltage, and EMP effects of lightning strikes, whose local fields are several orders of magnitude more powerful than anything the sun has ever thrown at the earth.
Any solar-originated pulse strong enough to "completely melt" any electronics in the plane will kill everyone and everything on the daylight-side of the planet, and probably strip the entire atmosphere.
Why and how would the electronics in an airplane be melted? Airplanes are naturally a Faraday cage, and all the components are going to be EMF shielded anyways.
The only thing an airplane would need to worry about with a solar storm is the increase in radiation exposure, and even then it's only relevant for the Flight crew who have limits on how much radiation they can be exposed to per OSHA.
That's not how earlths magnetic field induced current works...
The conductors on a plane are short, the induced current is tiny. Significant currents are produced in long conductors (transmission wires). Severely damaging the infrastructure they connect to, and potentially themselves.
True and I didn’t mean to imply it. Went for the hyperbole you tend to see and did a poor job with it after all.
