Stratospheric aerosol injection is a geoengineering technique aimed at reducing global warming. It involves releasing tiny particles, such as sulfur dioxide, into the upper atmosphere, specifically the stratosphere. These particles reflect some sunlight back into space, potentially cooling the Earth's surface. This method is part of a broader discussion on climate intervention strategies. While it could help mitigate climate change effects, concerns exist regarding its environmental impacts and ethical implications. Ongoing research is needed to understand the long-term consequences of stratospheric aerosol injection on weather patterns and ecosystems.
