FT Rethink

Solar radiation management could cool the planet. But at what cost?

2023 was declared the hottest year ever recorded, and our planet continues to heat up. It’s cast the spotlight on one of the more niche climate cooling solutions, solar radiation management, or SRM.

SRM works on the principle that the Earth can be cooled by reflecting some of the sun’s rays back into space. But as the FT’s Aime Williams explains, it could come with significant risks.


As the world changes at lightning speed, the FT Rethink series explores how to navigate transformative shifts shaping the future, from geopolitics and climate to industry, energy and health. The channel alternates between independent reporting from FT journalists and business perspectives from Lombard Odier.
