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.

pretty sure we're fucked.
https://www.cnn.com/2023/07/30/world/antarctic-sea-ice-winter-record-low-climate-intl/index.html
when the AMOC goes, we're gonna see ecosystems collapse. When the ice shelf breaks off into the sea, we're gonna see sea levels climb rapidly.
can human civilization survive? perhaps if we can get everyone to work together. ww2 levels of mobilization and federalization of resources.
I think this would require the UN to have a no-bullshit-session with the worlds top climate and systems folks, then each and every country declaring a national emergency to address the climate crisis. Which means we're going to finally have to get the assholes rolling coal in their giant pickup trucks festooned with trump flags to give up their bullshit. And everyone will have to cut their energy consumption and face changes to their lives and diets that will help us prepare for the really hard times ahead and feed the starving that are already resulting from mass drought & the war in Ukraine.
I doubt we'll ever get the rolling coal big truck assholes to give up their bullshit, so... No, we're fucked, we're going to die badly in most cases, and it's almost entirely our own fault. I let the last few generations off because they didn't enjoy the excess, they're simply going to get stuck with the bill.
Cheers, hope I'm very very wrong.
...Changes which will never happen and will themselves cause untold suffering and millions of deaths, so no one will ever support them.
What we need is a method that would not negatively impact human standard of living. Human expansion into space would do it; we'll require the energy and resources up there to geoengineer in a non-stupid way and get the energy and resources to get off Exxon-Mobil's oily cock and undo ocean acidification anyway.
So let's do that instead. We can prevent the civil war that would erupt from climate austerity too.
Dude - I'm really sorry, an escape hatch for the rich people who can pay to be onboard isn't a solution. We've been living unsustainably - this, by definition, can't be sustained. We need to change now so we can make that change as comfortable and human as possible; otherwise we're going to be stuck reactively responding to each successive disaster, or crop failure, or ecosystem collapse, or climate migration wave etc.
We need to get ahead, now.
Human expansion into space is anything but that and the idea that it is is just meaningless capitalist propaganda. Human expansion into space consists of:
Building space solar power stations (SSPSes) to beam power down to the Earth 24/7 to replace the coal plants
Mining calcium and magnesium from the Moon and near-Earth asteroids (NEAs) to bind with the excess CO2 in th oceans to stop and reverse ocean acidification
Mining rare-Earth elements from NEAs to mass-produce electric cars and batteries down here ln Earth to replace gas vehicles
Build O'Neill cylinders to preserve and rebuild ecosystems in safe places where poachers will never be able to reach
Among other things.
We don't have time for that.
The way I see it, we have 3 main paths
We cut everything we're doing, go local and human powered, and adapt to conditions as they change.
Super-intelligence and/or full automation (whichever comes first, we soon get both). It makes capitalism pointless, it lets us expand into space scaling geometrically, and it tells us exactly how we can change things here to maximize habitability
We keep doing what we're doing until the "just in time" supply chains we use to minimize costs collapse. Either the US military's plans for this are good and we minimize loss of life, or we starve. Industries collapse immediately, and maybe we lose the ability to produce higher technology - at the very least it won't be nearly as common. Hopefully we can still work on AI and robotics or there's no real way out of it
Path 1 is probably not happening. Path 2 and 3 are just a race between the next revolution in technology and the climate. It's looking pretty close right now - so doing anything to tip the scales, however slightly, is a great idea
It would take 5, maybe 10 years at most to build a Lofstrom loop making it possible to send out unmanned mining craft en masse, and then have the craft process minerals in zero g and then dump the calcium into the ocean. Furnish the magnesium into rebar and run a current theough it when it's stuck in the deep sea. We could even build nice seasteading islands at the same time with that approach -- create more living space while undoing the damage we've done to the oceans. Win-win.
Governments are running experiments on SSPSes now, in no small psrt because of climate change.
We absolutely can and should take the space approach now while we still have time.
Speaking of time, we can and should launch a solar shade up there to immediately stop the warming to give us the time we need to decarbonize, and clean up the oceans and forests. A solar shade will cool the Earth without the baggage and environmental problems associated with dumping sulfur dioxide into the atmosphere as the U.S. and EU are considering.
Of all the options, the solar shade might be the most mandatory, and would be very doable cheaply with a Lofstrom loop.
we need to turn this ship around without altering course, lol.
sure thing buddy, that would be great. not gonna hold my breath on that.
