SRM will act at the planetary level and necessitate autocratic governance

” There are also reasons to think that SRM will favour closed forms of decision making. Because of

its deployment at the planetary level, decisions would be taken at that level and over considerable

timescales, giving little opportunity for opt-out or dissent. Given the undoubted sensitivities that

would underpin its use, and the highly mediated nature of the effects of SRM, it could generate a

closed and restricted set of knowledge networks, highly dependent on top-down expertise and

with little space for dissident science or alternative perspectives.”
