The report uses a fictional 2030 scenario to analyze how various global actors would react to a proposed Arctic-based Stratospheric Aerosol Injection (SAI) deployment. It concludes that geopolitical instincts and existing rivalries, rather than scientific data, would drive initial responses, with Russia posing the primary security risk. The authors argue that a trusted multilateral scientific assessment and early trust-building are essential to prevent miscalculation and escalation.

The report details a 90-minute tabletop exercise simulating a nuclear maritime accident in the Bering Strait in 2050. The exercise identified critical gaps in Arctic infrastructure, including the fact that only 6% of Arctic waters are charted to modern standards and a lack of predictive atmospheric and ocean circulation models for winter conditions. Key findings emphasize the need for integrated indigenous emergency response infrastructure, the establishment of 'Confidence Building Measures' (CBM) with Russia to manage high-level nuclear contingencies, and the necessity of a common, multi-agency observation network to track changing Arctic storm patterns. The document argues that proactive research into radionuclide transport and the creation of an Arctic operations center are essential to avoid catastrophic failures in situational awareness and operational response.
