Stratospheric Aerosol Injection:
A study recently published in the journal Earth’s Future offered an innovative approach to Stratospheric Aerosol Injection (SAI) technique that could reduce its costs but also bring it closer to fruition despite the opposition to it.
- Stratospheric Aerosol Injection is a method of cooling the planet and reducing the impacts of climate change by adding a layer of tiny reflective particles to the high atmosphere.
- The method was inspired by volcanic eruptions, which have been known to have a cooling effect on the planet by spewing aerosols into the air.
- It aims to mimic the cooling effects of volcanic eruptions by injecting sulfur dioxide (SO2) directly into the stratosphere, where it forms sunlight-reflecting sulfate aerosols.
- Aerosols are tiny solid or liquid particles suspended in air or a gas.
- Aerosols can be natural, such as fog or gas from volcanic eruptions, or artificial, such as smoke from burning fossil fuels.
