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.

I hate this notation. 30 metres tonnes/hour? 30 millitonnes/hour? 30 megatonnes/hour? 30 metric tonnes/hour? 30 million tonnes/hour?
Context clues indicate it's probably 30 million tonnes/hour. Which is also Megatonnes (Mt).
Anyway, I digress.
I worked in the arctic for years. It's happening faster there than anywhere. Feedback loop where open water has a lower albedo and absorbs more sunlight...
There are more feedback mechanisms as well. For example permafrost melting, releasing huge amounts of methane from rotting organics which were previously frozen. Methane is way more powerful a greenhouse gas compared to co2. We are just finding out about a lot of this stuff in the past decade, which is accelerating global warming compared to models from 20+ years ago. Global warming isn't uniform as well, some parts like for example the arctic and parts of Western Europe are warming a lot faster.
Long story short, we need to be doing a LOT more than we are currently doing. And we seem to be doing very little, except pump all our money in large corporations and rich folks.
I know this probably a bad idea but what would happen if we tried to burn the methane as it comes out of the permafrost? Would it reduce the greenhouse gases?
It could backfire if it's anything like what happened in Turkmenistan.

Apparently it's been burning since the 80's
