Compared with climate hazards, many fewer studies have examined SRM risks-the potential adverse consequences to people and ecosystems from the combination of climate hazards, exposure and vulnerability-or the potential for SRM to reduce risk . Risk analyses have often used inputs from climate models forced with stylised representations of SRM, such as dimming the sun. Fewer have used inputs from climate models that explicitly simulated injection of gases or aerosols into the atmosphere, which include more complex cloud radiative feedbacks. Most studies have used scenarios where SAI is deployed to hold average global temperature constant despite high emissions.
