Stratospheric Aerosol Injection

Stratospheric Aerosol Injection (SAI) is a proposed climate engineering technique aimed at cooling the Earth by reflecting some sunlight away from the planet. This involves dispersing tiny particles, like sulfates, into the stratosphere, the second layer of the atmosphere. These particles can create a reflective barrier, similar to how volcanic eruptions can temporarily cool the climate. While SAI could potentially reduce global warming effects, it raises concerns about environmental impacts, disruption of weather patterns, and ethical issues regarding its use. Researchers continue to explore its feasibility and implications for addressing climate change.
