Stardust Solutions, an Israeli startup, is pioneering the development of microscopic silica spheres intended for solar geoengineering. These particles, if released into the stratosphere in large quantities, could potentially help cool the planet by reflecting sunlight. While the concept of using stratospheric aerosol injection for temperature reduction is not novel, Stardust's approach claims to offer unique benefits. However, the specific characteristics that make their particles superior remain undisclosed. This initiative highlights the growing interest and investment in solar geoengineering as a response to climate change challenges.
