GoKawiilSimulation finds global cooperation on solar geoengineering breaks down fast
Researchers and former officials gathered at Queen Mary University of London for a war-game exercise simulating how nations, companies and NGOs would respond to solar radiation modification technologies that could cool the planet by reflecting sunlight. Participants, including climate researcher Colleen Golja, played roles ranging from national governments to indigenous groups and tech firms, testing how a race to deploy such technology might unfold. The exercise revealed that reaching consensus on ethical, science-based deployment proved far harder than expected.
GoKawiil's interpretation of the reporting above, not reported fact.
The outcome suggests that even among experts predisposed to cooperation, geopolitical self-interest and uneven climate impacts could derail attempts to govern a technology with planet-wide consequences. Because solar geoengineering could help some regions while worsening droughts or storms elsewhere, the simulation hints that real-world negotiations may be even more fraught. Golja's surprise at the breakdown suggests policymakers may be underestimating how contentious geoengineering governance will become.
- A war-game simulated global response to solar radiation modification technology.
- Participants represented governments, NGOs, indigenous groups and tech companies.
- Cooperation on ethical research and deployment proved much harder to achieve than expected.
