Solar Geoengineering: A Technical Overview of Sulfur-Based Climate Intervention
Solar Geoengineering: A Technical Overview of Sulfur-Based Climate Intervention As global temperatures continue to rise due to anthropogenic greenhouse gas emissions, researchers are investigating advanced climate intervention strategies. One such approach is solar geoengineering , specifically Stratospheric Aerosol Injection (SAI) —a method designed to modify Earth’s radiative balance. What is Solar Geoengineering? Solar geoengineering refers to a class of climate intervention techniques aimed at reducing incoming solar radiation to cool the Earth’s surface. This approach is grounded in the principle of radiative forcing , a key concept in climate science that describes the imbalance between incoming solar radiation and outgoing infrared energy . By increasing Earth’s reflectivity (albedo), solar geoengineering seeks to produce negative radiative forcing , thereby lowering global temperatures. Stratospheric Aerosol Injection (SAI) The most studied ...
