Solar geoengineering

Solar geoengineering is a set of techniques aimed at reflecting sunlight away from the Earth to combat climate change. It includes methods like spraying reflective particles into the atmosphere or enhancing the reflectivity of clouds. The goal is to cool the planet and offset some effects of global warming. While these methods could potentially reduce temperatures, they also raise concerns about environmental impacts, governance, and ethical implications. Researchers are studying these approaches to understand their risks and effectiveness, as they are not a substitute for reducing greenhouse gas emissions.
