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.

The dinosaurs got wiped out and new life flourished. The same will happen again.
Oh then in that case nbd that we take millions of species who were living in harmony with nature with us. Serves them right for . . . existing in the same 20,000 year period we did.
Life is hard and unfair
The dinosaurs got wiped out by a catastrophic meteor impact (or so we think). This is different. We are changing the climate at an accelerated pace that's never been seen before. Species adapt to things over time. You can't adapt if the weather isn't stable, and things dip between super hot and super cold, or visa versa, they stay super hot or super cold. We have other examples of worlds like that in our solar systems, and they are dead worlds.
Permian Triassic extinction event is the one most similar to current situation.
There have been at least five major mass extinction events in the history of this planet. What will be after us in the future won't look like it does right now, but right now doesn't look anything like it did before any of those five events either.
As the saying goes, life finds a way. We just won't be around to witness it.
He said, right after mentioning a catastrophic meteor impact.
The two aren't equivalent. One of them was a one time event.
The sedimentation rate and thickness of K–Pg clay from three sites suggest rapid extinction, perhaps over a period of less than 10,000 years.
We're much faster than that.
Thanks, i hate it.
Humanity wins again, take that meteor!
I need to laugh, bcz if I wasnt laughing, I'd be crying.
How do you know that the climate is changing at a pace never before seen? Were you there to see it? There have been many mass extinctions in Earth's history. It'll be fine.
We know what the climate was like in the past by looking at layers in the earth, tree rings, even carbon dating can sometimes given evidence of how the composition of the atmosphere was in the past. There a lot of neat chemistry that we can use to learn what composition the atmosphere and climate had. Obviously there is some amount of error in models, but we do know.
I think there are a lot of errors in the models. Tree rings can only go back so far because most of the early trees are now coal. And trees, while they do live for a long time, don't live forever. Fossilization is rare and I don't know if we can get weather data from fossilized tree rings. Carbon dating is useful for organic matter up to 60,000 years ago. The other methods used to determine what the atmosphere was in the past include studying ice samples from Antarctica but that's only good for the time Antarctica froze till now, it was tropical at some point. Since most scientist think complex life has been around for 500 million years I don't think we can really say we know exactly what the climate was like and how it changed anywhere past a certain time period.
That's the problem. Thinking without actual evidence to back it up = your opinion. Having an opinion is fine. But in a discussion such as this you need to come into it with factual data.
It's the equivalent of showing up to a gun fight with a knife, believing you have a chance of winning.
Ok since you have a problem with the phrase "I think" then I'll add a source.
Here they say that Carbon-14 is commonly used for carbon dating but it's reliable for organic matter up to 60,000 years since it's half-life is 5,700 years. The rest of my post is questioning how accurate our knowledge is for older dates. Millions or tens of millions of years ago. How do we know the rate of weather change from millions of years ago just from fossils? I assume that the further back we go in time the more inaccurate we are on how the climate change and we can only know about the general climate from the plants and animals we find.
Also why didn't you question OP's source of data? They also made similar claims about what we know about what we know about climate change but no one questions their sources.
Info doesn't just come from fossils. Geology is used as well, ie; differing layers of sediment, rock, even layers of fossilized burned vegetation, flooding or lava flows form a basis to be able to judge earth's history.
That is why the older something is, the wider the scientific dating can be, ie: managed agriculture methods began around 12,000 yrs ago vs horses developed 45 to 55 million years ago.
Because the info OP gave is accepted science and can readily be found everywhere.
