Solar geoengineering startups are getting serious

Private companies are increasingly investing in solar geoengineering, a controversial method to manipulate the climate by reflecting sunlight back into space to combat global warming. Stardust Solutions, a startup in this field, recently raised a significant funding round, sparking concerns among researchers about the implications of private entities engaging in geoengineering. While some experts believe in researching geoengineering, they worry about profit motives and lack of transparency in private companies' involvement. Stardust Solutions asserts it will only proceed with geoengineering under government commission and regulatory oversight, but questions remain about the safety and transparency of their proprietary particles.
