The premise is based on the idea of solar geoengineering via stratospheric aerosol injection. Basically, it involves seeding the upper atmosphere with lots of tiny particles that can reflect some of the sun’s incoming rays back into space before they reach the surface, creating a cooling effect. It’s been theorized that dispersing around 5 million tons of pulverized diamond dust per year could lower global temperatures by nearly 2.9°F.
