Private Startup's $10 Billion Plan to Cool Earth Sparks Scientific Alarm
A startup called Stardust Solutions is developing particles to be sprayed into the atmosphere to reflect sunlight and cool the planet, in a project estimated to cost around $10 billion annually. Scientists warn of the risks of leaving such a globally consequential climate technology in the hands of a private company with insufficient oversight.
Why this matters
This story revives the long-standing debate over solar geoengineering as a controversial climate fix, but what stands out is a private company entering a field previously dominated by academic and government research. The absence of clear international regulatory frameworks for such interventions raises concerns about unilateral decisions that could affect global climate without broader consensus.
