The Technologies to Change The Climate
Geoengineering refers to the intentional, large-scale technological manipulation of the Earth's climate system to counteract the effects of climate change (Parson & Keith, 2024). These technologies are generally grouped into two major categories: 1. Solar Radiation Management (SRM) SRM technologies are designed to reflect a small fraction of the sun's energy back into space to cool the planet and offset the warming effect of greenhouse gases. These interventions do not remove carbon dioxide from the atmosphere, but rather mask the warming caused by it (Jinnah et al., 2019). Technology Mechanism Stratospheric Aerosol Injection (SAI) Injects tiny reflective particles (like sulfate aerosols or calcium carbonate) into the stratosphere. This mimics the cooling effect seen after large volcanic eruptions, where ejected ash and sulfur dioxide temporarily cool the Earth (Parson & Keith, 2024). Marine Cloud Brightening (MCB) Sprays fine parti...
