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 'future' is not inevitable. There have been countless collapses in history. Our technology doesn't make us immune. The people of the major Bronze Age powers probably thought the same.
Also we do not have the means for weather engineering. If you're talking about SRM, we have no idea what its consequences will be or how to do it effectively. It's all theoretical. No aircraft we currently have can do this stuff. Sure, we could design it and build one, but then you need global governance to actually implement it properly. Not to mention the risk of 'termination shock' and countless others.
Have a look at the scientific literature: https://www.semanticscholar.org/paper/Stratospheric-aerosol-injection-tactics-and-costs-Smith-Wagner/e4e5a78335eda8c16557b32af915798b06091362#cited-papers
Would you seriously risk the future of life on Earth on something this experimental?
I fear this arrogance will kill a lot of people and cause a lot of suffering.
Also
This kind of futurist accelerationist thinking hasn't turned out well in the past: https://en.wikipedia.org/wiki/Futurism?wprov=sfla1 It always ends up feeding into Fascism. I wonder why.
Somehow double posted. So this is now a blank comment.

It is already done. And the consequences are relatively easy to estimate. Much easier actually than the complex mechanics of world climate change.
Firstly, that isn't 'already done'. It's a PR statement from the Chinese government about plans. The stuff they have already done, like reducing hail etc., is nowhere near the same level to what is needed to stop climate change.
Secondly,
This is from your source ^
So is this:
Think of the geopolitical mess this kind of thing would create. If it works that is.
Well, there is always the option to use sunsails in orbit. These could also be motorised and adapt to the needed parameters.
There are a ton of solutions. And the weather and climate engineering is just one of them.
Sure, I like the idea of space megaprojects. I doubt sunsails in orbit would be profitable though. How would you monetise it? Put massive ads on them? Charge everyone a subscription fee?
Now, governments could probably do something like that, and I wouldn't be against it if safety and unintended consequences were taken into account somehow.
Also, I thought you believed space exploration tech was useless.
I agree there are many solutions. I don't think markets and capital are going to make them happen.
We can probably buy time with tech solutions. Long-term solutions will have to involve major fundamental sociopolitical change.
Well, a fee could theoretically be possible. Farmers with plants that need shadow could pay for shielding. In the end the end consumer pays the price.
👍
Let me rephrase it: it’s boring. Nada used old ass Russian rockets for years. So there is not much innovation there anyway.
I think that depends on demand. Some airlines already offer climate compensation packages. An additional payment to compensate your emissions. Such money could also be invested into sun shield projects.
I agree on the tech solutions. Let’s see them being implemented before chopping on the foundation of our economics.
A lot of those are scams or of questionable value unfortunately

I know that some people claim that. But in their mind they would rather stop airlines and flight overall.
And since this is unreasonable, compensation should be the second best step in your mind?
Because I don’t care. But from your standpoint it should be better than no compensation, right?
I'm actually in favour of replacing most jet airliners with rail and maybe electric airships. Most short-haul flights can be replaced by rail; it's much more pleasant than flying anyway. Jets can be reserved for long-distance journeys. Being able to hop on a blimp would be cool, even if it's slower. We can make them much better and safer with today's tech.
I don't like the 'green offset' thing because it makes it look like we're 'doing something' when it's actually not doing much at all. If you want to be a utilitarian, it would be much more effective to just donate to an effective charity every time you fly.
