What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

acid rain was legit, then the world's governments actually did something about it and it became not a thing. Much like the hole in the o-zone (at least until Elon's vanity satellites start failing at a high enough rate to decimate the o-zone) and how we could mitigate climate change if there was political will
Acid rain is real. So is quicksand. Either of them being common and severe hazards experienced across the entire US (and maybe elsewhere, I don't know what the rest of you were taught in gradeschool), not really.
Real acid rain causes mass ecological damage through relatively subtle increases in acidity over several exposures. The way we learned about it in school, whether they meant to or not, came across like concentrated hydrochloric acid was going to rain from the skies and melt human flesh on contact.
The solution to acid rain actually made climate change worse. Well, not directly, just that it turns out that the sulphurs in the atmosphere that caused acid rain were also cooling the planet. With that gone, heat went up quite significantly, and research is being done now to see if we can put that back again much higher and in a more controlled way to regulate temperatures down a bit. We could add additions to airplane fuel, for example, that will disperse it throughout the atmosphere
To your last sentence wouldn't that get in the way of contrail production though?
Not sure, it's something that's being looked into
