Stratospheric Aerosol Injection

Dan discusses the concept of stratospheric aerosol injection as a method to cool the planet, drawing parallels to past volcanic eruptions like Mount Pinatubo. He explains that injecting aerosols into the stratosphere could have a significant cooling effect, potentially requiring only a fraction of the sulfate emissions produced by human activities. This approach, while controversial, highlights the urgency of addressing climate change and the innovative strategies being considered to mitigate its effects.
