With about 100 mil worth of cash on an annual basis, you can pump enough sulfur into the stratosphere to cool the planet and keep the temps stable. It's pretty straightforward and a proven method (think volcano eruptions).

There's also iron seeding (to make algae). Bill Gates is funding it. I still think his work on Polio eradication is more valuable, but this is pretty awesome too.
- vlad_t 14y agoSpraying seawater also impacts in another way - produces a lot of aerosol (salt particles, and so on) which contributes a lot into pollution.

If you had a random country flagged ship and a bunch of SO2, you could pretty much just do this thing without telling anyone. They would presumably see it from satellites after atmospheric sampling (and people with eyes in the evening) noticed, but I'm unclear what the legal process would be to stop it.
