I don't actually disagree with this. My concern is that right now the public is very far from accepting the idea that we should engage in these projects, and they only exist at the research stage. Worse: convincing the world to accept near-term SRM (or even "use dirtier fuel again" SRM) may be a tough sell, since some portion of the world isn't convinced that climate change is very serious, let alone an existential threat that needs immediate action. Even if SRM works and is safe, getting from our current situation to one where we deploy SRM could take years, and I'm getting worried that we might not have those years.
