SAI would likely rely on aerosols being consistently sprayed into the atmosphere by a fleet of aeroplanes, as the particles have a half life of approximately eight months. The consequences of SAI could be far worse than a whitened sky. Poor coordination of aerosol release could lead to extreme rainfall in some places and blistering drought in others, further triggering the spread of diseases. This could produce ripple effects across the world’s ecosystems – but the exact nature of these effects depends on how SAI is used. To understand the risks, we’ve undertaken a risk assessment of this controversial technology.Ī cooler Earth means less water would be evaporating from its surfaces into the atmosphere, changing rainfall patterns. SAI could pose grave dangers, potentially worse than the warming it seeks to remedy. You can listen to more articles from The Conversation, narrated by Noa, here. This involves a fleet of aeroplanes releasing aerosol particles – which reflect sunlight back to outer space – into the atmosphere, cooling down the Earth. I definitely stand my ground when needed.A group of 60 scientists called for a moratorium on solar geoengineering last month, including technologies such as stratospheric aerosol injection (SAI).
