Why is that? Could you say something more?
Unknown second order effects Nearest real world success is continuous low volume maritime dispersal which has completely different dispersal dynamics than high-altitude bursts, and the continuous low volume maritime dispersal is non-viable No way to undo it once done If humans can’t perpetually release aerosols — and I mean perpetually , for the next millions of years — then the global climate “snaps back” violently…
I'm no expert in this subject and I don't have any strong opinions on it. The point of this comment isn't to debate one side or the other.
That said, your comment stands out to me to be self-contradictory and unscientific (by way of being alarmist and not backing up an extraordinary claim ).
> Unknown second order effects
This sounds right.
> Nearest real world success is continuous low volume maritime dispersal which has completely different dispersal dynamics than high-altitude bursts, and the continuous low volume maritime dispersal is non-viable
Since I don't know a lot about this topic I'll take your word for it.
> No way to undo it once done
This doesn't sound quite right, my intuition says more likely "no known way to undo it once done".
> If humans can’t perpetually release aerosols — and I mean perpetually, for the next millions of years — then the global climate “snaps back” violently within weeks
Wait... So, to undo it all we have to do is stop doing it? Doesn't this contradict the statement right before it?
> almost certainly eradicates all known life in the entire universe
This statement makes me suspicious of the credibility of the rest. This is an extraordinary claim and I think deserves way more explanation if you want to convince anyone who doesn't already agree with you. It would be a lot easier to accept "decimates human civilization" than "eradicate all life on earth". Life is extremely resilient.
How exactly would it eradicate all life on earth?

I’m far from being an expert but geoengineering gives me the shivers. Dumping boatloads of chemicals into the atmosphere, a lot can go wrong.
Fortunately, we have volcanoes that were doing it in an uncontrolled manner for a long time. I think we have survived.
conversely, the mechanism by which the KT impactor killed off the dinosaurs was atmospheric

#652025 was the third hottest year on record https://www.economist.com/science-and-technology/2026/01/14/...
Hottest of the last 100 years, but look on the bright side, it is the coolest of the next 100.

> Obviously it would be better to limit co2 emissions radically And to sequester hundreds of billion tonnes of co2, once humanity reaches carbon neutrality.
There was some promising research showing that you could recapture co2 and catalyze it into methane pretty efficiently. I wonder whatever happened to that. It'd be nice if we could continue burning "fossil" fuels by recapturing and reusing. With enough solar power, the efficiencies don't matter a lot. And with reuse we wouldn't have to change any of our chemical processes or equipment that we've already built in the…
Don't lie. Converting burned fuel into unburned one is not as simple as oxidation-reduction reaction at all. But also the CO2 in atmosphere is spreaded. If you remind that we can mine the inert gasses from the atmosphere - the amount of energy is worth of consideration in that case.

#67From a now dead comment, but still worth addressing since I've been seeing this as a dismissal for climate change a whole lot more lately:
> Even Bill Gates has admitted that it's not that concerning.
https://www.cbc.ca/news/science/bill-gates-memo-climate-chan...
https://thehill.com/opinion/energy-environment/5585562-bill-...
Tl;dr: Gates still thinks climate warming is a major threat, just not to the extent of using it as a doomsday threat of "guaranteed destruction for all of humanity."
I find it fascinating that climate change deniers will often say absolutely anything to discredit Bill Gates, but the second he says something that could even be misconstrued as support for their side, all of the sudden he's a trustworthy authority for their beliefs.

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".
I don't understand every comment as an invitation to debate. You can just not respond to people if you don't want to.

#70Looks like comments are being deleted on here... the climate change denial crowd is only growing :/
I mean there was not a single point in history when climate hasn’t changed. We literally live in a warm phase of Ice Age.
