Stratospheric Solar Geoengineering From Harvard
A group of private investors, including Bill Gates, are backing a solar geoengineering project to mitigate global warming.
It’s meant to mimic the effects of a giant volcanic eruption. Thousands of planes would fly at high altitudes, spraying millions of tons of particles around the planet to create a massive chemical cloud that would cool the surface.
Fires burning across the Amazon rainforest have renewed the debate about solutions to climate change. Bill Gates is backing the first high-altitude experiment of one radical approach called solar geoengineering.
Reminder - This Bill Gates-funded chemical cloud could help stop global warming

In his 2021 novel Termination Shock, science fiction writer Neal Stephenson describes this same method, as well as some possible problems
The elongated bowl, four thousand feet above sea level, in which this complex had been constructed, was referred to by T.R. as Pina2bo (“Pin a “two bo”). Anyone familiar with the literature on climate change and geoengineering would get the joke. Pinatubo was the name of a volcano in the Philippines that had exploded in 1991. It had blasted fifteen million tons of sulfur dioxide into the stratosphere. The result had been a couple of years’ beautiful sunsets and reduced global temperatures. The two phenomena were directly related. The sulfur from the volcano had eventually spread out into a veil of tiny droplets of H2SO4. Light from the sun hit those little spheres and bounced. Some of it bounced directly back into space—which accounted for the planet-wide cooling, as energy that never entered the troposphere in the first place couldn’t contribute to the greenhouse effect...Pina2bo would have to operate full blast for many years to put as much SO2 into the stratosphere as its namesake had done in a few minutes...
