Will protests at home hurt French President Macron's efforts to be seen as a leader of the West? Former U.S. ambassador to NATO Nicholas Burns digs in.

We here introduce the idea of highly decentralized solar geoengineering, plausibly done in form of small high-altitude balloons. While solar geoengineering has the potential to greatly reduce climate change, it has generally been conceived as centralized and state deployed. Potential highly decentralized deployment moves the activity from the already contested arena of state action to that of environmentally motivated nongovernmental organizations and individuals, which could disrupt international relations and pose novel challenges for technology and environmental policy. We explore its feasibility, political implications, and governance.
