How hard is it to dim the sun?

Solar radiation management is gaining traction as a climate intervention—but new research warns that real-world constraints make it riskier and more uncertain than most models suggest.

Can we dim the sun to fight climate change? Not without consequences

Scattering microscopic particles of sulfur in the atmosphere might slow down climate change. It might also change weather patterns.

Solar radiation management is gaining traction as a climate intervention, but how hard is it to dim the sun?

Once considered a fringe idea, the prospect of offsetting global warming by releasing massive quantities of sunlight-reflecting particles into Earth's atmosphere is now a matter of serious scientific consideration. Hundreds of studies have modeled how this form of solar geoengineering, known as stratospheric aerosol injection (SAI), might work.
