While computer modelling shows the technology might work to offset global heating in the short term, it also points to risks for global weather systems, particularly in South and South-East Asia, where billions of people depend on the annual monsoon.
Currently, there is no international regulatory framework for SRM, and many scientists have called for its ban altogether.
