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.

It might backfire and cause more problems.
Excuse my ignorance but with the way things are going. It's doesn't look like we have much to lose.
Do you remember hearing about Tambora, Krakatoa and their global effects? Do you remember ozone crisis? How we found out about the severity of the impact lead had on people? Acid rain? Nuclear winter?
Effective and thus extensive geoengineering requires an understanding of biogeochemical processes that we don't have.
Well we didn't solve those by doing nothing. And given how unwilling we seem to be in reducing our footprint. I'd say this is our only viable way.
The only way is endangering food supply and if we stop we might have hyper climate change?
Nuclear winter didn't happen and the jury is out of it could happen that way. Everyone knew lead was bad but the thought was because it was heavier than air the dust would settle quickly, tests in real life conditions showed that it didn't. The ozone thing yeah give you that.
But we HAVE so much to loose. At the moment, even a worse case scenario is one when earth goes on and adapts. Even humans would likely survive. And it's not even decided we'll get that.
But as proven time and time again by the shitty predictions we are getting, we don't have anything close to a true understanding of the systems in which we live.
So on top of that, you'd prefer a single nation, most likely with economic interests well active in their decision making, to try and forcefully modify the system we don't really understand?
Count me out.
I would love to live in a world where a few powerful nation did have such influnce that their economic interests didn't screw over the world. But i was born in a world like that.
What makes you think this? Do you have a source for this? I am genuinely curious here.
Because we could eat phytoplankton and moss which could take care of oxygen production. We couldn't swim in the oceans or spend much time outside but we create digital fake worlds for ourselves.
Humans are unfortunately and fortunately very scrappy inventive creatures that a lot would have to happen to completely wipe us out. It's not to say the future wouldn't be miserable and unlike anything we currently know but the will to keep on living is very strong on average.
It's unlikely and pretty hard to get a runaway Venus effect on earth but not impossible, but it would be likely to restabilize at some point and life would go on. It takes a lot of effort to sterilize a planet even if not nearly as much to fuck with its balance.
How? All the ideas that are being looked at come from natural cycles that are being exploited. No one is talking about releasing some chemical that no one understands up there they are talking about causing algae blooms, inducing acid rain in the middle of the oceans, and painting stuff white. This isn't cutting edge. Also it isn't a one and done deal, it will require constant infusing of cash.
We know that sulfur and dust in the area lowers temperatures. The experiment has been run before. Look at average temperatures and see what happens around the WW2 era where steel has to be made using cheap dirty sulfur rich coal quickly.
We know painting stuff white makes it reflect more energy.
We know that alga eats a lot of carbon and sinks. We also know that alga is always limited by a few trace elements it can't get enough of.
None of this stuff is new. All of it is going to cost a fortune every single year. Presumably if somehow someway painting stuff white made things go crazy we would stop spending tax dollars on it.
