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.

to be fair records only go back like 200 years tho but it is still telling about the direction
TBF you can also pretty know the temperature from thousands of years ago somehow accurately by analysing ice from the polar caps
Yeah but the original toot is only taking about measured temps, not proxy temps.
they have daily readings from cores?
Yearly. They look at slices generated by compressed layers of snowfall. Thick layer = cold year. They look at more stuff but that's roughly how it works.
edit: not sure why you're downvoted. It's a good question.
Also the composition of captured gasses dissolved in the ice help us see what the atmosphere was like back then
It's a really cool field to look into NGL
The herd acts in mysterious ways... one would have thought we left those practices in the R-site...
I don't mean to disagree or argue, but I still think this is a delicate point.
We are moving Earth out of the climate in which humanity emerged, survived, lived and prospered.
Some point out how terrible it would be to stop using oil and coal. Which it would. But on the other hand - we survived 200'000 years without oil and coal, but we never had to endure the climate in which we are speeding right now.
I think we mostly have the same point. I just find it worth noting the climate has not been this hot ever in the whole of mankinds existence.
Geology disagrees
Yes... that is how records work lol...
https://en.wikipedia.org/wiki/Global_temperature_record
Yes, proxy measurements are a thing lol.
Human's are pretty damn great at predicting issues and surmising evidence of the future and past based on current findings.
We don't call our current epoch the Anthropocene for no reason.
The original toot clarified that they were talking about direct measurements only (but evidence exists that this is the warmest period in the last 125,000 years).
approximation is not a record tho
Ah yes, approximation is not a record therefore we cannot consider it a factor at all, regardless of it being our best estimate given our current data. You're right, let's throw it all out and opt for ignorance. 🙄
i suggested no such thing, you made that last part up for yourself.
i am just highlighting that comparing data from different sources/methods of collection is not proper apples to apples comparison. but sure have a melt down over it lol
No you're acting like we can't use this as a data point when it's the data we have. It may not align apples to apples, but we have a recognizable trend that aligns with/exceeds predictions. I don't see the point in doubting the data we have.
I'm sure we would take ice samples from the modern era, ya know if any new ice was being deposited. Other systems are pretty easy to correlate 1:1.
Just because something isn't digital doesn't mean it doesn't exist or we can't take observations from it.
I don't mean digital. Just daily readings with a thermometer across the globe v 1cm or whatever per year of a core reading for that location or a few of them.
How far are you planning on moving those goal posts?
This Wikipedia page honestly has some of the best climate change graphics I've seen anywhere. They're simple, fact-based, concise and paint a pretty obvious and telling picture.
