Geoengineering, Explained: Reflecting Sunlight vs. Removing Carbon
Geoengineering involves deliberate, large-scale climate interventions, broadly categorized into Solar Radiation Management (SRM) to reflect sunlight and Carbon Dioxide Removal (CDR) to extract atmospheric CO2. Both approaches carry distinct mechanisms, risks, and governance challenges, and neither replaces the necessity of emissions cuts.
