Solar geoengineering aims to manipulate the climate by sending sunlight back into space. In theory, this could reduce global warming. But as interest in the idea grows, so do concerns about the potential consequences.
A startup called Stardust Solutions recently raised $60 million, the largest funding round for a geoengineering startup to date. My colleague James Temple has a new story about the company, and how its emergence is troubling some researchers.
So far, this field has been limited to debates, proposed academic research and – of course – tracking a few marginal actors. Now the matter is becoming more serious. So what does this mean for geoengineering and climate? Read the full story.
