The thing is, this is not a one time solution. We would have to do it continuously, or else the temperature would quickly rise again. And we would have to increase sulphur injection if the CO2 level keeps rising. It could be a temporary solution though, e.g. until all countries switch to nuclear energy eventually and reduce CO2 emissions.
Sulphur at least is more natural, as it's also released by volcanoes.

I'm not sure what to take from the natural comment or if it's serious... Natural things can be profoundly bad for the earth and things that live on it, like poison... Or volcanos...
Also salt water, incredibly natural it turns out.
Thankful that there’s no real emergency yet, but I suspect governments will drag their feet long enough that there will eventually be one, and then emergency relief will be deployed anyway, but it will cost way way more than 5bn.
That said, we won't stop fossil fuel exploration and the related emissions, so yes, it's temporary.
Cover Greenland in a reflective blanket?
Sounds like it is time to panic...and actually do what needs to be done.
> Cover Greenland in a reflective blanket?
Ha! I want to see a study on this now. Greenland already has high albedo so it wouldn’t be that effective; it would protect the ice sheet but also be covered by new snow, if any.
I'm confused. CO2 will still be in the atmosphere warming the planet once emissions stop. So we'd still need to be constantly emitting sulfur.
How? Where does the carbon go?

Stratospheric sulfur is much more efficient, per kg, at reflecting sunlight, so we could replace the cooling effect of surface-level sulfur with stratospheric sulfur, and if we choose to, go even further to cool the planet more.
