The 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.

but it doesn’t prove there won’t be worse side effects from adding new stuff into an already complex problem

You mean China and India which are building coal power plants at record pace as we speak.

Whataboutism. The truth is that neither China nor India will ever reach the cumulative emissions of the US, probably by a very large margin. Those who have already put the most CO2 into the atmosphere have the greatest moral responsibility to become CO2-negative yesterday – and to do everything they can to help other, less wealthy countries do likewise.

Earlier quoted context omitted.

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.

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 within weeks and almost certainly eradicates all known life in the entire universe.

Good lord, read Termination Shock by Neil Stephenson. Stratospheric aerosol injection is effective, but comes with severe risks, and can even be used as a strategic weapon (e.g. inject your sulphur over X and disrupt the monsoon in the Punjab, fucking their agriculture).

While they do, 2025 was also the first year that the fraction of coal dropped in both China and India. In india it dropped by 3% and in China by 1.6%. So they build out fossil, but they build out non-coal power faster. China also hopes to peak coal in absolute terms by 2030. That's something at least.

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.

Weapon of mass de-desertification.

You can spray it from anywhere, source it from god knows where. What flavor of snowcone do you want this week?

China is also building renewables and nuclear at record pace and their per capita emission is much lower than USA. If we also take historic emission into account (and we should - the CO2 from decades ago is still in atmosphere!) then China still has a lot of budget to catch up with USA. Honestly, the China argument is getting really tiring.

Careful now, that is dangerously close to admitting weather manipulation has been known about and possible for decades, and not merely a conspiracy.

I’d love to see the raw data.
