Stratospheric Aerosol Injection
- As climate change accelerates and global emissions continue to rise, researchers are revisiting a controversial idea — cooling the planet by injecting sunlight-reflecting particles into the atmosphere.
- Stratospheric Aerosol Injection (SAI) is a proposed climate intervention that involves spraying reflective particles like sulphur dioxide into the stratosphere to reduce the amount of sunlight reaching Earth’s surface.
- The technique is inspired by volcanic eruptions, which have historically caused temporary global cooling by releasing aerosols into the upper atmosphere.
- Most SAI models recommend injecting aerosols at high altitudes (above 20 km) near the equator, which requires specially designed aircraft.
- Simulations using ....
