Scientists Divided Over Solar Geoengineering Research and Deployment
Scientists are divided on the progression and deployment of solar geoengineering, also known as solar radiation modification (SRM), which aims to temporarily cool the climate by altering the amount of energy entering or leaving the Earth system. The most prominent proposal, stratospheric aerosol injection, involves releasing sulfur dioxide high into the atmosphere to form reflective particles, mimicking the cooling effect of volcanic eruptions. While small-scale outdoor field experiments are being considered to improve computer models and understand atmospheric processes, critics argue that such research could create momentum towards larger trials and eventual deployment, potentially normalizing a technological approach to climate management. There are also proposals for marine cloud brightening and cirrus cloud thinning. The debate extends beyond scientific evidence, touching on concerns that SRM could detract from efforts for transformative social change and sustain existing economic systems, rather than...
