Israeli Startup Stardust Raises $75M for Solar Geoengineering; Scientists Warn of Risks

Stardust Solutions, an Israeli startup, has raised $75 million to develop technology that would inject microparticles into the atmosphere to dim sunlight and cool the Earth by 0.5°C. Scientists warn this could destabilize global climate systems. The funding signals growing private investment in controversial geoengineering, but regulatory and scientific uncertainty remains high.
