The Naval Air Station Oceana Dam Neck Annex faces significant risks from sea level rise, with projections indicating that up to 75% of the installation could be underwater during daily high tides by 2100 under a high-emission scenario. The analysis warns that by the end of the century, a Category 1 storm would expose at least 95% of the station to storm surge flooding, and a Category 4 storm could result in nearly 60% of the installation flooding to depths of 20 feet or more. The document argues that there is a growing gap between current military preparedness and these threats, calling for increased funding for high-resolution modeling, tide gauge networks, and detailed mapping to implement adaptive measures.

The Portsmouth Naval Shipyard in Maine faces significant risks from sea level rise, with projections indicating a rise of 3.5 to 5.9 feet by 2100. Without preventive measures, the installation is expected to experience frequent tidal flooding, the loss of over 25% of its land area in the highest scenario, and increased vulnerability to storm surges from Category 1 and 2 hurricanes. The document argues that there is a growing gap between current military preparedness and these threats, calling for increased funding and high-resolution modeling from Congress and the Department of Defense.

Naval Station Norfolk is located in a sea level rise hot spot where seas are projected to rise between 4.5 and 6.9 feet by 2100. Projections indicate that by 2050, some areas could flood 280 times per year, and by 2100, up to 60% of the station's land area could be exposed to flooding during extra-high tides. In the highest scenario for 2100, a Category 4 storm could leave 95% of the base under more than 10 feet of water. While the Navy has invested in raising piers and participating in regional studies, the document argues that a large gap remains between current preparedness and future threats, calling for increased funding for high-resolution modeling and detailed mapping.

The document projects that sea levels at NSB Kings Bay will rise between 3.7 and 6.1 feet by the end of the century, leading to more frequent tidal flooding and severe storm surge. Under a highest-scenario Category 4 storm in 2100, nearly 95 percent of the base could be flooded, with over half of that area under 20 feet of water. The author argues that there is a large gap in military preparedness and calls for Congress and the Department of Defense to provide high-resolution modeling, funding for tide gauge networks, and resources for detailed mapping and adaptive planning.

NAS Key West, a 5,800-acre installation providing critical training and support for US military operations, faces significant risks from rising sea levels. Projections for the Florida Keys indicate sea levels could rise between 3.8 and 6.2 feet this century, threatening land that currently sits at elevations of three feet or less. The document argues that a large gap exists between current military preparedness and these threats, calling for increased funding for high-resolution flooding models, tide gauge networks, and detailed mapping to implement long-term adaptive measures.

USCG Station Sandy Hook, a critical life-saving and security installation in New Jersey, faces significant risks from rising seas. Projections indicate that by 2100, sea levels in the area could rise between four and 6.4 feet. Under a 'highest' scenario, nearly three-quarters of the station's land area could flood with daily high tides by 2100. Additionally, the area exposed to five feet or more of seawater during Category 1 storm surges is projected to increase from 30% today to roughly 80% by 2100 under an intermediate scenario. The document argues that there is a large gap in military preparedness and calls for increased funding for high-resolution modeling, tide gauge networks, and detailed mapping to implement adaptive measures.

The report evaluates the "Salt Marsh Stories" program's impact on four focal audiences: Audubon members, higher education students/faculty, and business and faith communities in Maryland's Eastern Shore. Baseline data shows that salt marshes and sea level rise are generally non-salient issues, with significant uncertainty regarding sea level rise. However, the experiential program—specifically the planting of native grasses—successfully increased place attachment, knowledge, and emotional engagement. The study identifies place attachment and affinity for nature as the strongest predictors of a participant's intent to communicate about these issues to others.

The Union of Concerned Scientists analyzed 18 strategic US military installations on the East and Gulf coasts, finding that most face significant risks from rising seas. Under a 'highest' scenario of sea level rise, some bases could lose between 75 and 95 percent of their land area by 2100. The report highlights that tidal flooding frequency will increase steeply, and storm surges will reach further inland and with greater depth. It emphasizes the need for high-resolution mapping and regional collaboration, noting that the vulnerability of surrounding low-income and minority communities can further compromise base operations.

The document details the technical approach used by the Union of Concerned Scientists to evaluate coastal flooding risks for US military bases. It describes the use of the NOAA SLOSH model for storm surge, the NOAA Inundation Analysis tool for tidal flooding, and Mean Higher High Water (MHHW) levels for permanent inundation. The analysis utilizes localized sea level rise projections for 2050, 2070, and 2100 based on the 2013 National Climate Assessment. Key caveats include the exclusion of rainfall-induced flooding, the use of worst-case 'Maximum of the Maximum' storm surge scenarios, and the fact that the study provides illustrative snapshots rather than a comprehensive risk assessment of all bases.

The document outlines a bottom-up risk assessment of seven infrastructure categories in El Salvador, estimating an average annual loss of US$35.5 million. It identifies earthquakes and floods as the primary drivers of loss and recommends integrating these findings into local planning and climate change adaptation strategies.

The document argues that transitioning from fossil fuel-based electric power to clean renewable energy is a public health imperative. It details how climate change exacerbates respiratory, cardiovascular, and mental health issues, and how the Clean Power Plan's goal to reduce carbon pollution by 32% below 2005 levels by 2030 will prevent thousands of premature deaths and asthma attacks. The toolkit provides clinicians with messaging and model letters to influence state policymakers, while explicitly arguing against nuclear power due to radiation risks and waste management failures.

The document details a CDKN-supported project in Belize that identified up to 70% of the coastal tourism sector as vulnerable to climate-related impacts, including coastal erosion, flooding, and biodiversity loss. It highlights the role of 'grey-green' infrastructure and the adoption of a national integrated coastal zone management plan in February 2016 to enhance resilience. The study emphasizes the importance of stakeholder engagement, the use of interactive mapping tools, and the integration of ecosystem services into national policy to protect critical natural assets like mangroves and coral reefs.

The document details a CDKN-supported project (2013–14) that used Regional Climate Models (RCM) to assess future flood risks in Jamaica. Key findings include the high vulnerability of coastal tourism infrastructure in Negril to sea-level rise and the critical intersection of major roadways with high-likelihood floodplains. The study emphasizes that current risk assessments are hindered by low-resolution climate models (50 km) and a lack of high-quality topographical and hydro-meteorological data. It recommends the adoption of laser technology for terrain mapping and continuous GIS training for local government staff to improve disaster management.

The Union of Concerned Scientists proposes a climate resilience framework based on narrowing the 'resilience gap' through combined mitigation and adaptation efforts. The report outlines 15 principles categorized by rigorous science, equitable outcomes, and ambitious common sense to ensure adaptation is scientifically sound and socially just.

The report assesses Myanmar's natural capital, focusing on four key ecosystem services: sediment retention for water quality, dry-season water availability, flood risk reduction, and coastal protection. Using InVEST models and climate projections, it identifies critical areas where natural ecosystems support human populations and infrastructure. The findings indicate that while the volume of services (such as sediment retention) will likely change due to increased rainfall under climate change, the geographic 'hotspots' of these services are expected to remain stable. The report emphasizes the overlap between these service-providing areas and Key Biodiversity Areas (KBAs), arguing that protecting these synergies is vital for both human resilience and wildlife conservation. It specifically highlights the Tanintharyi region as an example of where infrastructure projects, like the Dawei road, could threaten critical natural capital.

The Maldives is implementing a GCF-funded project starting on Sh. Funadhoo and expanding to 48 other islands to combat water scarcity caused by altered monsoon patterns and tsunami contamination. The project focuses on rainwater collection, groundwater quality, and distribution networks to reduce reliance on expensive desalination. This initiative is part of a broader national adaptation plan including zoning and erosion control, while highlighting the gap between current GCF funding and the global climate finance mandate.

Miami-Dade County faces significant risks from sea level rise, including a projected increase in tidal flooding from six events per year currently to over 380 by 2045. The document highlights threats to real estate, drinking water via the Biscayne Aquifer, electricity infrastructure, and the Everglades ecosystem. It emphasizes that pre-disaster investments are fiscally responsible, potentially saving four dollars for every dollar spent on mitigation, and calls for federal support to protect disadvantaged communities and reduce global emissions.

The briefing highlights research indicating that global sea levels could rise by several meters within 50 to 150 years if emissions grow, potentially submerging major global cities and displacing 20% of the world's population. It emphasizes that these impacts could occur even if the 2 degree C target is met. For Canada, the document details 2010 emission sources and advocates for a societal transformation, specifically noting that closing coal-fired power plants in Ontario and Alberta provides a rapid pathway for emission reductions and health benefits.

California is experiencing significant damages from climate change, including increased heat-related mortality, more frequent and severe wildfires, and rising sea levels. The state faces critical water shortages, record-low snowpacks in the Sierra Nevada, and a high risk of extinction for 83 percent of its native freshwater fish species.

The report details two readiness requests: one for Vanuatu to develop Climate Information Services (CIS) to support adaptation and disaster risk reduction, and one for Senegal to establish a pipeline of privately funded, grid-connected solar projects to address an acute energy crisis.
