I remember reading about the cooling effects of aerosols about a decade ago. It's not like this was a mystery even back then.

#24This story is from 2024? Seems a bit dated

#25The good news is that this pretty much proves we can somewhat slow down climate change by spraying certain chemicals into the air. Obviously it would be better to limit co2 emissions radically, but that's not going to happen thanks to the idiots who rule America these days.
The prospect of geoengineering is the only thing which gives me some hope for the future.

#26Looks like comments are being deleted on here... the climate change denial crowd is only growing :/
Are they? I thought you couldn't delete your comments on here?
I think this is one of the "worst" features of HN.
Ephemerality and forgetting are important for society and we need more of it.
I'd really like to see someone from the EU push for GDPR Right to Forget, or CCPA.

You are allowed to delete your comments for a short time, as long as no comments are posted in response.
I'm not sure what happens with down votes on a deleted comment.

You should do some reading on why there are few actual climate scientists pushing this idea, and instead it’s mostly people with totally unrelated backgrounds like marketing or economics.

#29Earlier quoted context omitted.
You can, but only briefly. HN gives you a short “oops window” to delete comments. Officially it’s for typos. Unofficially it’s a dignity rollback mechanism for people who realized mid-thread that they don’t actually understand what they’re talking about.
Eh, even when I understand what I'm talking about, sometimes I submit a comment and then instantly realize "you know what, I actually don't want to debate this with a random stranger on the Internet".
People will never admit they don't know what they're talking about.

For those not understanding why aerosols dimming the sky is not a solution is it won't stop ocean acidification and obviously just slows down the warming, not stopping it.
The thing we need to do is remove CO2 but unfortunately that will take more energy than putting it up there is in the first place.
