Aria, the UK government's Advanced Research and Invention Agency, is quietly investing 71 million dollars into geoengineering projects like Marine Cloud Brightening and Stratospheric Aerosol Injection to slow global warming by reflecting sunlight away from Earth. Founded in 2021 with a broad one billion dollar budget and minimal oversight, Aria funds speculative, high-risk research, but faces criticism over its secrecy, high executive salaries, and lack of transparency. Although projects are still in early phases, some experts warn that such interventions may have unintended and irreversible side effects on the climate, questioning the wisdom of investing taxpayer money into unproven technologies.
