Ask Lemmy
A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, toxicity and dog-whistling are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !askusa@discuss.online
7) No Hit-and-Run questions.
Please don't delete your post for no apparent reason. If you plan on deleting a question later, say so in the post, or if you feel that you have a good reason to remove it, message a mod beforehand. It's not fair to the ones who took their time to answer, and it's not in the spirit of the community.
Reminder: The terms of service apply here too.

It seems kind of unlikely. It could be part of an array of solutions. Right now it captures something like 0.1%. That means it would take 1000 times the current infrastructure to support it, including carbon-neutral energy to cover the additional energy costs. All that is assuming 100% carbon capture is even viable. Even then, that doesn't solve the problem of the carbon that's already in the environment, which will continue to warm the earth for centuries.
There's an interesting emergency option: Stratospheric aerosol injection.
If we got to the point where the runaway effect was unavoidable, it might be possible to use this before civilization starts to collapse. It would probably have a lot of nasty side effects, but it might be able to buy enough time for CO2 levels to come back down. At least civilization could survive in some form.
