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.

I think it's a combination of hubris and desperation. Hubris because it could still go very wrong and serve us a frozen extinction instead of a boiling one. Desperation because those who acknowledge what's happening know that something probably needs to be done to not only stop but reverse this but the corporations might be more likely to burn it all down protecting their interests than cooperate.
The "easy" solutions will likely lead to war and might not even help anything at this point. The promising technologies still need to be scaled up (also in a way that makes sure we don't overshoot the cooling targets or remove so much CO2 that plants die out).
The more I think of it, the more I like this desperate idea. If it does work too well, we can always just send more rockets to move whatever it is out of the way. Which we should have built and ready to go shortly after the blocker is deployed. Preferably sitting in orbit to minimize the chances of it screwing up if desperately needed.
Hmm sunlight is also a carbon reducer since it drives photosynthesis. But desperate times...
All I can think of is the last episode of the show Dinosaurs. This is the wax fruit factory and the bunch beetles all over again, except with us as the stars of our own show.
God damn was that a downer ending for a lighthearted sitcom. That kids watched. I didn't see the final episode until I was an adult, but I bet a bunch of kids were traumatized when it first aired.
Imagine if, instead of the four of them ending in jail at the end of Seinfeld, they died in a nuclear holocaust. Or if How I Met Your Mother ended with zombies eating the whole gang while we watched them scream. I'm guessing that was the level of trauma for kids watching the finale of Dinosaurs.
It was a total downer. As an adult, I don't watch that episode anymore. It had some enjoyable content, but I can't start it because of how bleak it gets. Otherwise, that show is probably among my top 50.
The main aerosols proposed for SRM also cause ozone depletion and acid rain. There is some level of control as to where the bad consequences and up and which regions get more extreme weather.
Anyone want to take a guess as to which countries won't end up with the consequences?
