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.
-
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 OCTOBER 19 2025
-
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.

'Sharp acceleration' meaning 75% faster warming in the last decade compared to the 40 years previous, and blowing past the 1.5° target in 3-4 years. No speculation was given, but I think it's likely we're seeing the limits of oceanic absorption of co2 and heat. The ocean's latent heat capacity has flattened the curve for more than a century, and it's very hard to predict when that will run out, but sea surface temperatures spiking all over have been good evidence that we have passed a major tipping point in the last few years.
They also banned sulphur oxide in ship fuel which would have had a cooling effect, that was hiding the full extent of the damage and is slowly dissipating
Won’t be long until we start doing that again on purpose
How great fixing pollution with more pollution.
🎵 The solution to pollution is...more pollution? 🎵
Actually it's kinda good news as it shows we can make direct impact to the climate. Just with a substance actually made for it.
Don't take it too seriously, there is an effect but it's not that large. And anyways, the change in maritime fuel standards happened in 2020, while this trend goes back to 2015. A geoengineering project is just going to cause more problems, we don't know nearly enough about how the world works, truly.
Geoengineering is the only thing that can really blunt this at this point...
Delaying the collapse of civilization by changing the chemistry of the atmosphere further will only serve to hurt the entire ecosystem to allow a few more years of our planet-wide rape. Decarbonizing was the only hope for both human civilization and Earth to survive together. Our choice now is to accept that or possibly kill everything in desperation.
Death from overheating the entire earth < Death from near constant acid rain?
Acid rain is not that big of a deal, the amount of sulfur over oceans isn't really a problem. Acid rain is only an issue in certain areas. Sulfur emissions aren't global.
Good news is cloud seeding is viable? Bad news is we're probably gonna need it.
I’ve read that the models used to predict the rate of change were too optimistic or an assumption about them was too conservative and thus not very realistic. Now we have data showing the models under-predicted the rate of change, so one argument is that we were already on this path since decades ago, we just didn’t model it right.
In any case, we’re all fucked so who gives a shit anyway no?
Is there a name for when we know what the right thing to do is but we keep not doing it?
Great Filter.
No way in hell we're facing an extinction event. Unimaginable human suffering, probably, but humanity will persist.
Really depends on what happens with phytoplankton; if they can adapt well enough to survive the excessive heat. Some of them can but others are dying out. If we lose all of them, then everything that breaths oxygen is extremely fucked since they make ~70-80% of that oxygen. Then we only have plants and forests like the amazon to make O^2^ (and we all know how that ones going), and then we would also have to deal with the gasses produced by all the oceans on the face of the earth dying and everything in them rotting... if they're not par-boiled.
Isolated pockets in relatively protected areas. Global society won't survive it. Most of the places we grow food won't be able to grow food, that's already accelerating. Ocean acidification kills that food source. Blue ocean event accelerates runaway heating leading to massive hurricane force continental storms. Amoc shuts down and Europe ices over. Humanity may persist but civilization won't.
that's just not true! higher temperature makes food grow better, not worse.
Yes, that's what I said
Vast current areas become arid but vast areas in Siberia and Canada become arable. Very bad but not extinction for humans. Likely extinction for many species though.
that's also not true! vast current areas become ~~arid~~ tropical. see the tropical rainforest. it's the hottest and simultaneously wettest regions on earth.
We are driving 200 species extinct a day and that figure is increasing every year. Eventually we run out of nature and we go with it.
The temperature on the planet has never in its history changed so abruptly, which means plants and animals don't have enough time to adapt.
None of that thawed soil will be worth a damn for growing at any scale. Like yeah there will be areas that are more or less hospitable but large scale agriculture will not recover
We are adaptable creatures with command of technology. So we've got that going for us. We also have temperature limitations in which we can live, and so do our food sources. Then there's the issue of potable water.
It really depends on how far we're pushed the planet's ecosphere. It could do like before (most recent is the PETM) and hover high, then eventually equalize back into something not the same as we had, but similar. It's done this before, albeit after millions of years. Or it could find a new equilibrium in another state, aka hothouse. Not Venus-like, as some media has spun it, but its own version of feedback to retain a lot more heat than now. Not great for anything that evolved in this climate.
Fun fact: the PETM was the most recent heating event, 56 million years ago. Some species went extinct, others were able to adapt and survive as they evolved into smaller forms. The fun fact is that they adapted because the rate of heating change was over a large amount of time, many hundreds of thousands of years. Now look at us, a spike on the geological temperature graph in (looks at data) less than a 100 years (a few decades, really). So what kind of inertia does a more rapid acceleration usually give compared to a slower one? But hothouse Earth is just a speculation, just a guess. We don't know how far this will go.
But will that subsequent civilization get to space again?
I’ve often wondered… What if we are way wrong about the level of danger, and ultimately climate change will turn Earth into another Venus, and we only find out once it’s too late?
History has taught that humanity wont stop until it has gone too far.
Hubris.
All of the climate models have adjustable parameters. We are still within the bounds of the worst case scenarios but scientists are always afraid to claim too much. An academic's reputation is a lot less recoverable than a pop star or politician in the sense that they, and their colleagues, actually take their words and predictions seriously. I don't want to completely dismiss the effect of lobbying and corruption toward the downplaying of global warming, but making smaller-than-necessary claims is a common sight in most academic fields.
I think it's mostly in fields with exponential outcomes, which experiences the too conservative estimates.
We as a species has a really hard time understanding exponential/accelerant movement, we expect the next decade to change as much as the previous one. Despite every decade has been changing more than the previous one did
Sometimes I open up nullschool and just stare at the El Niño on the southern pacific. Looks like a gaping wound.
