The policy brief argues that climate change threatens US national security by damaging critical infrastructure, increasing state fragility, and intensifying geopolitical competition. It recommends that the US government implement a National Adaptation Plan, integrate 'Operational Resilience' into military budgets, scale up resilience funding for strategic allies, and strengthen interagency coordination on the food-climate-security nexus to protect US interests and economic competitiveness.

The study analyzed chlorophyll concentrations from 1997 to 2017 using SeaWiFS and MODIS Aqua data across four Large Marine Ecosystems (LMEs). It found significant increases in chlorophyll concentrations in large portions of the Patagonia (PLME) and Humboldt (HLME) ecosystems, while increases in the South Brazil (SBLME) and Pacific Coastal Central America (PCACLME) ecosystems were limited to smaller regions.

This white paper, based on a 2024 scientific diplomacy workshop in Panama, outlines the critical role of estuaries and mangroves in Central and South America for biodiversity, climate regulation, and coastal protection, while providing policy recommendations for their conservation and restoration.

The report analyzes marine geoengineering, dividing it into marine carbon dioxide removal (mCDR) and marine solar radiation modification (SRM). It argues that these speculative technologies pose irreversible risks to ocean ecosystems and human rights, while facing significant monitoring and verification challenges. The authors contend that proposed deployment zones span every ocean basin, making the impacts inherently transboundary and potentially violating international law, including the CBD moratorium and UNCLOS.

The Latino Climate Justice Framework 2025-2028 outlines systemic inequities facing Latino/a/e communities, including higher energy burdens, exposure to fossil fuel pollution, and lack of access to nature. It proposes specific policy objectives across energy justice, climate resilience, worker protections, and migration rights, while warning against 'false solutions' like carbon capture and storage. The framework emphasizes the need for equitable clean energy transitions, the protection of climate-displaced persons, and the liberation of Puerto Rico from restrictive energy and economic policies.

The report finds that human-induced climate change significantly increased the frequency and intensity of extreme heat globally from May 2024 to May 2025, affecting billions of people and making all 67 identified significant heat events more likely. It highlights the disproportionate impact on vulnerable populations and the systemic failure to accurately document heat-related mortality, while advocating for a combination of urban heat action plans and aggressive fossil fuel mitigation.

The author contends that the global food system has reached 'peak land' and that decoupling agricultural land use from food production allows for the retirement of marginal land. By paying farmers to stop farming unproductive areas, the document suggests that environmental services can be restored and GHG emissions reduced by 20-40% if 5% of farmland is retired by 2030 and 10% by 2050.

The project utilizes paleotempestology—analyzing sediment cores from lagoons, stalagmite isotopic records, tree rings, and corals—to reconstruct past tropical cyclone activity. Key findings indicate that higher sea surface temperatures in the Atlantic correlate with increased hurricane activity, with notable peaks during the Medieval Warm Period (AD 900-1100) and since 1980. The research also identifies an inverse phase relationship in hurricane landfalls between Central America, the Eastern Caribbean, and the US East Coast, suggesting that the Intertropical Convergence Zone (ITCZ) and tropical anticyclones are critical drivers of coastal risk. Additionally, the study expanded its scope to the Pacific coast of Mexico, identifying an extreme event in Baja California Sur approximately 500 years ago.

The coffee sector in Mesoamerica, comprising approximately 580,000 producers—mostly smallholders with less than 5 hectares—is highly vulnerable to global price volatility and extreme weather events. Between 2000 and 2003, the region saw a 44% decrease in coffee trade earnings and the loss of 500,000 jobs for heads of households. While some farmers have adapted through organic production, fair trade, and social organization, others have been forced to diversify into non-agricultural activities or migrate. The document argues for a stronger public sector leadership to implement policies that combine indigenous knowledge with financial mechanisms (such as insurance and micro-credit) and social capital to improve long-term sustainability and climate resilience.

The report identifies the intersection of food insecurity and climate change as a critical threat to US national security, citing risks such as political instability, the weaponization of food by adversaries, and geopolitical competition over agricultural technology and fish stocks. It highlights gaps in the US policy landscape, including institutional silos and underfunding of agricultural R&D. To address these, the authors propose 'The Feeding Resilience Plan,' which recommends a new Food Security Executive Order, a standing National Security Council process, expanded forecasting via FEWSNET, increased investment in climate-resilient agricultural innovation, and diplomatic engagement to oppose food weaponization and cooperate with partners and competitors like China.

Between March and May 2024, global temperature records were broken for three consecutive months. Using the Climate Shift Index (CSI), the analysis found that approximately one in four people worldwide experienced temperatures at least three times more likely due to climate change (CSI level 3+) daily. Exposure peaked on April 6, 2024, with 2.7 billion people affected. The most severe impacts were concentrated in Africa, Southeast Asia, Central America, and South America, with 44% of Africa's population experiencing the most extreme attributable heat (CSI level 5 for 60+ days). The report also highlights a strong regional contrast in the U.S., where coastal areas and islands showed higher CSI signals despite lower temperature anomalies compared to the Upper Midwest.

Using the Climate Shift Index (CSI), Climate Central found that human-caused climate change significantly boosted spring warmth in 2024, affecting 300 million people in the U.S. and approximately one in four people globally. The strongest influence was observed in coastal and island regions, such as Puerto Rico and Florida, while areas with the highest temperature anomalies, like the Upper Midwest, showed lower CSI levels due to higher historical temperature variance.

The document details a roundtable event focused on the 'climate-food-security nexus,' arguing that the US must integrate defense and security actors into food security efforts to maintain stability and military readiness. Key recommendations include improving actionable intelligence through tools like the Climate Security Alert Tool, combating illegal, unreported and unregulated (IUU) fishing through security cooperation, and increasing public investment in agricultural research and development.

The IAI Executive Directorate is relocating its headquarters to Panama following a decision by the Conference of the Parties on March 26, 2024. The transition involves drafting a Headquarters Agreement to be approved by the National Assembly of Panama, with the process expected to align with the new government taking office on July 1, 2024. To ensure operational continuity, the IAI has requested that its current diplomatic privileges and bank accounts in Uruguay be extended until July 31, 2025.

The IAI Directorate has proposed a Strategic Plan for 2024-2030 organized around three themes: meeting the needs of Parties to address global environmental change, developing science for the sustainability of the Americas, and ensuring the sustainability of the IAI as an organization. Key initiatives include funding transdisciplinary research on the climate-environment-health nexus, biodiversity, and ocean-coast-island systems through the Belmont Forum, as well as expanding the STeP program and establishing a new office in Central America and the Caribbean by 2025.

The report identifies that climate change creates systemic stressors for the UK Home Office, ranging from direct threats to public health and infrastructure to indirect risks like societal polarization and organized crime. It argues that the Home Office must move from a reactive to a proactive posture by establishing a high-level climate security policy initiative. The proposed Action Plan is built on four pillars: exercising sustained leadership, understanding and anticipating risks through better data and literacy, collaborating with domestic and international partners, and implementing specific preventative measures to protect citizens and maintain social cohesion.
