Hedged Rejection of Solar Geoengineering

Governments may publicly oppose solar radiation modification on precautionary grounds while deliberately leaving regulatory and normative debates open. That posture signals risk aversion without preempting private development, creating a governance gap as firms (e.g., Stardust Solutions) move toward operational capability within a decade. — This pattern forces urgent international regulatory design: if states only 'aren’t in favor' while private actors progress, unilateral or clandestine SRM deployment becomes a plausible geopolitical and environmental risk.
