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.
-
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.

This has been looked at and methane pockets are burned sometimes. When extracting oil for example there is often a lot of methane, which is burned to turn it into co2. The problem is, we are talking about a huge area with not many people or infrastructure in them. Sometimes the methane builds up in pockets which then can be burned easily, but most of the time it's out gassing over a big area with very little methane per square meter. Capturing that methane is not practically possible.
Maybe some combination of sheets which are reflective to reflect sunlight instead of absorbing it and at the same time direct the methane to a place where it can be burned off. But doing this across a large area would be hard and would also have an impact on the environment, so it would be a hard calculation to find out if it's worth it. And getting funding for something like that is pretty hard. Plus a big chance of failure, what if the sheets crack after a couple of years and get fouled up, then the methane isn't captured, the sunlight isn't reflected and a lot of time and energy has been lost. Plus you have a big patch of nature filled with plastics to clean up.
Methane does naturally get destroyed due to uv radiation, so it isn't long term like co2. But it's way more potent in terms of greenhouse and we've been releasing a lot more than gets broken down. Levels of methane are at a all time high and rising. On a human timescale the methane will take a very long time to get broken down, even if we would stop releasing any right now.
There are satellites specifically made to detect large releases of methane, to identify human sources of methane which could be captured and burned instead of being released. Especially in industrial processes this is often an option.
Large scale meat production is also a large source of methane, which is also hard to capture. Especially when we want the cows to have somewhat of a acceptable state of living, so going outside. The only way to fix this one is for people to eat less meat, however the trend has been for more and more meat consumption instead of less.
Burning natural gases from the ground has backfired before:

It didn't happen to save the environment, but there was too much natural gas stored to burn off.
How fast does methane breakdown with UV? Is that a practical way to deal with the permafrost methane?
