War Games Reveal Geopolitical Volatility of Solar Geoengineering

While the scientific capacity to cool the planet via solar radiation modification is widely accepted, a recent simulation suggests the primary risk is geopolitical instability. The war game, titled "Exploring Geopolitical Tipping Points and Climate Cooling Strategies," brought together scientists, military personnel, and government officials at Queen Mary University of London to stress-test the global response to these technologies.

According to reporting from Wired, the simulation revealed a landscape dominated by distrust. Participants representing the U.S. and China refused to sign international deals that constrained research deemed to be in their "national interest" or allowed a rival to take a technological lead. Major Jeffrey Nielsen, a U.S. Army officer in the simulation, described the stance as viewing any deal favoring China as "worse than no deal at all."

As the simulation progressed through 2027 and 2028, tensions escalated over suspected research missions and disinformation. The game featured a scenario where China approached a representative from SpaceX regarding a technology-sharing program, which was promptly reported back to the U.S. team.

These risks emerge as private sector interest grows. Wired reports that U.S.-Israeli startup Stardust Solutions raised $60 million last year, and Elon Musk has publicly stated on X that massive geo-engineering and space satellites will be necessary to avoid a "game over" scenario. Former UN advisor Cynthia Scharf told Wired that governance decisions regarding this technology will likely be required within the next decade.
