Geoengineering aims to intervene in Earth’s climate to fight global warming.

A group of 60 scientists called for amoratoriumonsolar geoengineeringlast month, including technologies such asstratospheric aerosol injection(SAI). This involves a fleet of aeroplanes releasing aerosol particles – which reflect sunlight back to outer space – into the atmosphere, cooling down the Earth.

SAI might make the skyslightly whiter. But this is the least of our concerns. SAI could pose grave dangers, potentially worse than the warming it seeks to remedy. To understand the risks, we’ve undertaken arisk assessmentof this controversial technology.

A cooler Earth means less water would be evaporating from its surfaces into the atmosphere, changingrainfall patterns. This could produce ripple effects across the world’s ecosystems…
