A company called Stardust Solutions has a plan to help cool the planet. The plan involves producing tiny particles from a food additive and a mineral, then spraying them into the atmosphere. This method is part of a technology known as solar geoengineering, which aims to bring down global temperatures by dimming the sun.

Stardust Solutions is an Israeli-US company founded in 2023, led by former Israeli government nuclear physicists. The company is pushing ahead with developing this technology, despite controversy surrounding it. Further details about the company's plan and the concerns surrounding solar geoengineering are available.

Scientists have raised concerns about this plan, but the company estimates it can be implemented for $10 billion a year.
