ResearchSolar Geoengineering: A Complex Puzzle, Not a Simple Fix for Climate Change
Solar geoengineering, particularly Stratospheric Aerosol Injection (SAI), is frequently framed as a last-resort 'emergency brake' for climate change. However, a closer examination reveals that this approach is less a simple mechanism and more an intricate, largely unsolved puzzle, fraught with significant practical, ethical, and governance challenges that demand rigorous scrutiny.
