That's a pretty good article considering it's the NYT, who proudly accepts direct fossil fuel blood money on the regular and even produces pro-fossil advertorial content. I wonder if anyone posting on this thread will have actually read it? It's not advocating for the tech at all. Almost everything in there is people saying it's a terrible, dangerous idea.
The reality is, this tech is going to happen. There will be countries that deploy it to try and produce cooling effects for themselves. China is ALREADY doing similar things. Better to do the research on it than pretend it doesn't exist and wait for magical space faeries are going to come down and sing a song that sparks a global moment of kumbaya. Especially since the most likely outcome of research on the tech is going to be the conclusion that it is not a viable mitigation strategy at any useful scale. Because of course it is. Even though we know it's possible to modify atmospheric reflectivity to create cooling effects, it's obviously a maddening act of hubris to think it ever could go smoothly.
