This gets at what I think is a fundamental problem with most well-intentioned, public minded SRM work — the governance requirements for ethical SRM would seem to be a subset of the governance requirements that would allow any plausible need for SRM to be avoided.
One needs to go back to Crutzen 2006 to find the same message I have: in order for SRM to work, public trust and public buy-in will always be necessary. Stardust’s methods go in the diametrically opposite direction. Their investors might tell themselves they’re concerned with climate change, but…
