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.

Mass extinction events have a cause. The Permian/Triassic one I mentioned, is generally agreed to be from unusual movement of earth’s crust, creating severe volcanic activity.

I think you'd get your point across even better with less understatement.

Let's put it this way: by "severe volcanic activity," what you really mean is that an area roughly the size of Europe was buried half a kilometer deep in lava!

We have barely existed on earth, but are throwing it off balance like never before. (With the exception of the meteor that killed the dinosaurs, but that’s a whole other tangent)

I think we may very well be on par with the meteor, TBH. Especially in the worst-case emission scenario.

(Speaking of the K-Pg meteor, another large igneous province, similar to but smaller than the one at the P-T boundary, was basically the "exit wound" of that meteor impact. It could very well be that the P-T extinction was caused the same way, but all evidence of the crator would have been obliterated by subduction over the past 250 MY because the antipode of Siberia back then would've been somewhere in the middle of the Panthalassic Ocean. Edit: I take that back; turns out there is some evidence for it that managed to survive, so that's neat.)

Thank you for adding more information. I love reading more about this stuff. It would make sense if a meteor was related to the P-T volcanic activity. It would easily have enough force to mess with the crust of the earth.
