New research indicates that solar radiation management through aerosol injection faces significant practical obstacles that climate models overlook. Scientists highlight deployment complexities, material shortages, and unpredictable climate consequences that could undermine geoengineering efforts.

The Reality Gap in Solar Geoengineering

Solar radiation management, once considered a fringe concept, is now gaining serious scientific attention as a potential climate intervention strategy. However, according to reports from Columbia University researchers, the practical challenges of implementing stratospheric aerosol injection (SAI) are being dramatically underestimated. While hundreds of studies have modeled how SAI might work to offset global warming, sources indicate there’s a significant gap between idealized simulations and real-world implementation.
