A war game in London simulated global governance of solar radiation modification, revealing how quickly ethical considerations collapse under geopolitical pressure. Participants—including scientists, diplomats, and military officials—played nations and organizations responding to rapid advances in climate-cooling technology. The exercise, titled Exploring Geopolitical Tipping Points and Climate Cooling Strategies, showed that without binding international agreements, a unilateral race to deploy geoengineering is likely.
Technologies like stratospheric aerosol injection could cool the planet but carry severe regional risks, including droughts in sub-Saharan Africa and intensified Atlantic storms. Private firms like Stardust Solutions are already investing millions, and figures like Elon Musk have publicly endorsed the idea. The simulation underscored that decisions about governing such powerful tools may arrive within a decade, not decades, and that science alone cannot prevent a chaotic rollout.
