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.

And what do YOU know about radioactive waste disposal?
I know it's a damn lot easier than carbon recapture, if we're talking waste products. It's not ideal, but there is no such thing as perfect, and we shouldn't let that be the enemy of good. Nuclear fission power is part of a large group of methods to help us switch off fossil fuels.
"Easier"? Are you aware of the fact that radioactive waste tombs are meant to stand for millions of years? It requres a lot of territory, construction and servance charges, and lots of prays for nothing destructive happens with it in its "infinite" lifetime.
Have you tried capturing gas? As difficult as radioactive waste tombs are, they're easier than containing a specific type of air lol.
Read about breathing if you want to know how to capture gas. Also, about photosynthesis.
If you want to buy the land to plant a second Amazon, be my guest. And breathing does the exact opposite of what we want.
I'd rather fill land with trees than with radioactive wastes.
You need a lot, lot more trees. Like several orders of magnitude. And growing trees takes longer than even building a nuclear power plant.
To be specific, growing the types of trees we would want for such a thing in such an amount that it would deal with the problems we have, assuming we stop growth of CO2 and assuming we stop burning the Amazon, would take around a hundred years.

"It could take more than a hundred years to add enough mature forest to get sufficient levels of carbon reduction. Meanwhile 40 billion tons of carbon dioxide (CO2) from burning fossil fuels are being added to the atmosphere every year, said Glen Peters, research director at Norway’s Center for International Climate Research."
And need an area the size of the United States. I wasn't joking about a second Amazon.
I'd rather this as well, but we don't have that many choices. The slower we act and the more we let perfect be the enemy of good, the more people die.
Launching radioactive waste into space is a terrible idea, because rockets on occasion crash. Once that happens it becomes a nuclear disaster.
Instead we can safely store it in depleted mines.
Big hole in the side of mountain in a desert, stick the waste in, full it with rubble and concrete, job done. If some primatives in a hundred thousand years stumble across it and dig it out, fuck em, who cares.
The pyramids have chambers that were unopened for over four thousand years, bone dry inside. Pick an area with very little rainfall, surround it with rock and the problem will stop existing on human timescales.

There is no guarantee of anything.
But if you're storing it hundreds of miles from the ocean, the risk is minimal.
That is not what I am suggesting.
Sealing a deep narrow borehole isn't a difficult problem. The Earth has contained oil and gas underground for millions of years.
The hole would be 0.5m wide and >1000m deep, backfilled with bentonite clay and concrete. At the bottom, the path curves back upward, so waste is not stored at the bottom.
Even if geology doesn't collapse the hole, it's hard to imagine material climbing up through 1000m of clogged pipe.
We can bury it in the ground and it will literally turn into lead. How are you doing with carbon emissions? Got a fix?
I think it's photosynthesis. 'Bury in the ground' is an extreme simplification btw. Also, I am finished with this topic scince long anough. It feels politically biased. If you'd like to reply, I'd hear it gladly. But I m not going to be involved into a discussion.
