Geoengineering

Geoengineering through stratospheric aerosol injection (SAI) is a proposed climate intervention technique that involves spraying reflective particles, such as sulfur dioxide, into the stratosphere to reflect sunlight and reduce global warming. The concept mimics natural processes like volcanic eruptions, which temporarily cool the planet by releasing aerosols into the upper atmosphere. Proponents argue it could provide a rapid, cost-effective way to mitigate rising temperatures, especially as carbon reduction efforts lag.
