Stratospheric Aerosol Injection: A Risky Climate Distraction?

2/20/2026

Summary

Story summary

Stratospheric aerosol injection (SAI) aims to reduce global temperatures but does not address greenhouse gas emissions.
Critics argue it could exacerbate climate harms and disrupt regional weather patterns.
Evidence from volcanic eruptions and climate models suggests SAI could alter weather dynamics, making it a risky distraction from essential climate policies.
Effective climate action should prioritize reducing emissions, enhancing resilience, and investing in sustainable development rather than relying on geoengineering.
