The Company That’s Raised $60 Million to Geoengineer the Planet

For more than 30 years, a heterodox group of scientists have proposed injecting sulfate aerosols into the stratosphere to reflect sunlight away from Earth, thereby cooling the atmosphere and reversing climate change.

But actual research into the idea has remained taboo, or at least the province of university and government labs. Then, last year, Heatmap broke the story of an Israeli-American company named Stardust Solutions that had raised $60 million to develop a new solar geoengineering technology. This system would be easier to control and track than the traditional approach to geoengineering, it claims.

On this episode of Shift Key, Rob is joined by Yanai Yedvab, the cofounder and CEO of Stardust. They discuss why Stardust is researching geoengineering now, whether a for-profit company belongs in the space, why Yanai believes Stardust’s particles are superior to sulfate aerosols, and whether Stardust has or will ever conduct outdoor experiments.

Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap News.
