Geoengineering – how I got interested

I had a vaguely weird feeling about it. In a very unrealistic and sci-fi way I started imagining myself standing up the day the operations start. Everything is very silent, and, like everyone else in the world, I am looking up at the sky, and planes start pouring long clouds of sulfates in the air, making everything look a bit more dull, a bit more yellow, or is it grey?
