The document argues that biological threats can rapidly degrade military readiness, as seen during the COVID-19 pandemic. It evaluates three types of respiratory PPE—Filtering Facepiece Respirators (FFRs), Elastomeric Half-Mask Respirators (EHMRs), and Powered Air-Purifying Respirators (PAPRs)—based on protection, source control, wearability, and logistics. The author recommends a tiered approach: government-managed stockpiles of EHMRs for baseline protection, vendor-managed inventories of FFRs for high-volume use, and investment in flexible surge manufacturing capacity.

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 argues that South Korea's heavy reliance on imported fossil fuels (84% of total energy supply) creates critical vulnerabilities to geopolitical conflicts in the Strait of Hormuz, Malacca Strait, and South China Sea, as well as climate-driven infrastructure risks. It posits that a rapid shift to renewables can mitigate these risks, reduce financial burdens associated with energy price volatility, and support the energy needs of advanced AI and defense systems. While acknowledging challenges such as China's dominance in critical mineral supply chains and cybersecurity risks associated with digitalized grids, the document concludes these are manageable through battery storage innovation, grid modernization, and supply chain diversification. It recommends integrating renewable energy goals explicitly into national security planning and the 12th Basic Plan for Electricity Supply and Demand.

The report argues that South Korea's heavy reliance on fossil fuel imports—approximately 84% of its total energy supply—creates significant national security vulnerabilities due to geopolitical tensions and climate risks. It posits that transitioning to renewable energy would reduce exposure to fragile maritime chokepoints, lower fiscal strain, and improve military readiness. While acknowledging challenges such as China's dominance in critical mineral supply chains and cybersecurity risks from digitization, the report concludes these are manageable compared to the structural risks of fossil fuel dependence. It recommends integrating renewable energy targets into national security planning and leveraging the newly created Ministry of Climate, Energy and Environment to coordinate a whole-of-government approach to energy resilience.

The document explores how sunlight reflection methods (SRM), such as stratospheric aerosol injection (SAI) and marine cloud brightening (MCB), interact with global security. While SRM could mitigate climate-driven security risks by lowering temperatures, it may introduce new tensions regarding its use and outcomes. The briefing distinguishes SRM from cloud seeding, noting that while the latter has a history of weaponisation (e.g., Operation Popeye), SAI and MCB are too imprecise for direct weapon use but could still be used for general disruption. It argues that large-scale deployment would be difficult to hide due to detectable infrastructure and atmospheric effects. Two hypothetical scenarios are presented: one involving military tensions in the Arctic over an SAI programme and another involving accusations of drought in South Asia. The authors recommend building trust, transparency, and using scenario gaming to manage these security challenges.

The report finds that while over 75% of NATO countries include climate change and nearly 70% include food security in their security strategies, these issues remain siloed. Most concrete actions focus on military emissions mitigation and direct adaptation rather than the indirect security implications of food and water insecurity. The author argues that climate-driven disasters create vulnerabilities that adversaries like Russia and China exploit through disinformation, weaponized migration, and food weaponization. The report recommends updating NATO's baseline resilience requirements and targeting investments toward "stability multipliers" that address the nexus of climate, food, and security both domestically and in the developing world.

The policy brief advocates for a transition from traditional antibody-based and PCR diagnostics to aptamer-based technology to improve outbreak response and biosecurity. It highlights that aptamers—synthetic nucleic acid sequences—can be developed in weeks, produced without animal cells, and digitally distributed for local manufacture, thereby reducing supply chain vulnerabilities. The author argues that this capability enables 'deterrence by denial' by signaling to potential perpetrators that engineered bioweapons would be detected rapidly. The brief recommends that US agencies including ARPA-H, DARPA, ASPR, NIH, FDA, and USDA fund rapid-response platforms, establish regulatory pathways, and integrate these diagnostics into agricultural biosecurity.

The report argues that South Korea's heavy reliance on imported fossil fuels (84% of total energy supply) creates critical security vulnerabilities exposed to geopolitical conflicts and climate-driven disruptions. It posits that a rapid shift toward renewables can mitigate these risks, reduce financial burdens on the state, and support the energy demands of advanced defense and AI technologies. While acknowledging challenges such as China's dominance in critical mineral supply chains and cybersecurity risks associated with grid digitalization, the document concludes these are manageable through diversification, battery storage innovation, and strategic policy integration.

The FY26 NDAA includes at least 24 provisions affecting US biodefense, featuring a mix of strategic advancements and institutional losses. Key positive developments include prohibitions on contracting with adversary-owned biotechnology providers to protect multiomic data, the establishment of a DoD Biotechnology Management Office, and the creation of a wastewater surveillance pilot program. Conversely, the act codifies the dissolution of the National Counterproliferation and Biosecurity Center (NCBC) and maintains restrictions on the National Nuclear Security Administration's (NNSA) ability to run an enduring bioassurance program. The document also highlights efforts to enhance intelligence sharing on biotechnological threats and the authorization of $137,686,000 for the Biological Threat Reduction Program.

The report argues that maintaining secure maritime food trade is a US national security imperative, as disruptions to key chokepoints—specifically the Suez Canal, Panama Canal, and Strait of Malacca—can trigger cascading global risks. Using a strategic foresight approach, the authors analyze four scenarios based on the uncertainty of international cooperation and port infrastructure resilience. They find that climate stressors, such as a projected global warming increase of over 2°C by 2040, threaten agricultural productivity and port operability. These vulnerabilities can be exploited by hostile actors, such as Al-Shabaab in Somalia, to weaponize food and destabilize regions. The report recommends that the US incorporate maritime food trade resilience into its National Security Strategy, invest in climate-resilient infrastructure, and revitalize flexible development assistance to prevent the erosion of soft power and protect military supply chains.

The Council on Strategic Risks reports a decline in US federal biodefense investments for FY26, with total requests at $27.02 billion. While biosurveillance and medical countermeasures remain priorities, the report highlights significant funding cuts to global health security, public health preparedness, and domestic health capacity. It also notes a trend of declining transparency and agency reorganizations across HHS, DoD, State, and DHS that complicate the tracking of biodefense expenditures.

Colorado is experiencing a rise in billion-dollar climate disasters, with an increase from 1.7 annually since 1980 to 4.4 per year between 2020 and 2024. The state faces critical threats from wildfires, flooding, avalanches, and drought, which impact public health, infrastructure, and the economy. Federal agencies including NOAA and FEMA provide essential forecasting, research, and funding for mitigation, such as the $13.8 million BRIC grant for the Greely Water Pipeline. However, proposed FY26 budget cuts and the cancellation of programs like BRIC threaten to shutter research labs in Boulder, eliminate cooperative university partnerships, and reduce funding for climate-smart agriculture and critical mineral surveys, potentially increasing the vulnerability of both local communities and military installations such as Buckley Space Force Base and Fort Carson.

Washington State faces escalating risks from drought, wildfires, extreme heat, and coastal flooding, which threaten its economy, ecosystems, and critical US military installations. While federal agencies like NOAA and FEMA provide essential forecasting, funding, and disaster recovery services, the report argues that recent and proposed budget cuts for FY2026—including the termination of key research laboratories and the reduction of grant programs—significantly degrade the state's capacity to prepare for and respond to these hazards.

Hawaiʻi faces significant economic and security risks from sea level rise, wildfires, and drought, which threaten both civilian infrastructure and critical US military hubs like Joint Base Pearl Harbor-Hickam. While federal agencies provide essential monitoring and recovery support, proposed FY 2026 budget cuts would eliminate key programs such as the Hawaiʻi Sea Grant and the Pacific Islands Climate Adaptation Science Center, potentially reducing disaster relief and hindering climate adaptation efforts.

The document advocates for the use of ventilation, filtration, disinfection, and monitoring to mitigate the spread of airborne biological threats. It highlights that clean indoor air serves as a 'day-zero defense' when medical countermeasures are unavailable and is essential for maintaining military readiness and cognitive performance. The brief details specific technologies, such as HEPA filters and far-UVC light, and notes the current inadequacies in ventilation within federal and military facilities.

The report analyzes Russia's strategic use of climate-related disinformation to advance geopolitical goals. It details how the Kremlin exploits climate disasters in the West to stoke polarization, suppresses domestic environmental activism to prevent unrest, and manipulates narratives in the Arctic and Africa to secure economic and political influence. The document highlights the intersection of Russian influence with far-right rhetoric and the emerging threat of AI-driven disinformation, while arguing that subnational and international cooperation is essential to counter these efforts as US federal defenses weaken.

The policy brief examines how water scarcity empowers non-state armed groups, delegitimizes state authority, and fuels transboundary disputes, while proposing that the US utilize its technological leadership and mediation experience to maintain geopolitical stability.

The report analyzes climate adaptation projects in Afghanistan, the DRC, Haiti, the Horn of Africa, Mexico, Myanmar, and Papua New Guinea. It finds that while insecurity often leads to risk-averse site selection and implementation delays, projects that integrate conflict-climate nexus analysis and prioritize bottom-up, community-led approaches can mitigate conflict and foster peace. The authors recommend flexible implementation, holistic monitoring and evaluation, and the explicit inclusion of conflict mitigation in project objectives to avoid maladaptation and 'backdraft'.

The report examines climate adaptation in Afghanistan, the Democratic Republic of the Congo, Haiti, the Horn of Africa, Mexico, Myanmar, and Papua New Guinea. It finds that while instability often leads to risk-averse site selection and implementation delays, projects that integrate conflict-sensitivity and community-led approaches can mitigate these challenges and potentially contribute to peacebuilding. The analysis highlights the necessity of flexible implementation, the use of fragility assessments, and the importance of addressing root causes of vulnerability to avoid maladaptation and 'backdraft'—unforeseen negative spillover effects.

The document describes a high-intensity confrontation between India and Pakistan on May 10, which involved air incursions, missile strikes, and drone battles, nearly escalating to nuclear war. It argues that the reliance on tactical nuclear weapons acts as a critical accelerant in the rapid transition from limited conventional conflict to nuclear signaling.
