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 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 project focused on integrating climate model rainfall projections into flood risk assessments for Jamaican communities. It emphasizes the necessity of flood hazard maps that account for future climate change to support disaster management and climate compatible development. Key recommendations include providing ongoing geospatial data training for local government and parish-level disaster coordinators, and improving cooperation between academia and government bodies to ensure high-quality data informs life-saving policies.

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.

Bangladesh is highly vulnerable to sea level rise, flooding, and cyclones, leading the government to establish early adaptation frameworks like the National Adaptation Programme of Action (NAPA) and the Bangladesh Climate Change Strategy and Action Plan (BCCSAP). While the country has created dedicated institutions and funds, such as the Bangladesh Climate Change Trust Fund (BCCTF), adaptation efforts have predominantly focused on large-scale infrastructure in coastal urban areas, often neglecting sectors like livestock and regions prone to drought. Despite being a major recipient of international climate finance, disbursement remains fragmented, and there is a significant gap between planned budgets and actual leveraged funds.

The report identifies 'climate equity hotspots' along the U.S. East and Gulf Coasts, where projected sea level rise and tidal flooding combine with socioeconomic risks such as poverty and minority population share. It argues that federal and state agencies must prioritize these vulnerable communities in funding and infrastructure investments to ensure an equitable response to climate change. The analysis evaluated thirty-five coastal counties across nine states and provides case studies for five specific locations, including Dorchester County, MD, and Plaquemines Parish, LA, to illustrate the challenges of environmental injustice and sinking lands.

The Union of Concerned Scientists developed a screening tool to identify coastal 'climate equity hotspots' where high climate risk overlaps with socioeconomic vulnerability. Applying this to 35 counties across the East and Gulf Coasts, the report finds that low-income and minority communities face disproportionate burdens from sea level rise and storm surges, often exacerbated by inadequate disaster recovery policies. It advocates for targeted federal funding, inclusive stakeholder engagement, and the use of actionable science to build resilience in frontline communities.

The Union of Concerned Scientists (UCS) report identifies coastal communities where socioeconomic vulnerability and climate risks overlap, creating 'climate equity hotspots.' Using a pilot study of 35 counties across nine U.S. states, the report demonstrates that African American, Latino, and Native American communities often face higher exposure to sea level rise and tidal flooding while possessing fewer resources to adapt. The authors propose a screening tool based on climate and socioeconomic indicators to guide more equitable distribution of federal and state resilience funding. The report concludes with policy recommendations to upgrade affordable housing, improve transportation for evacuations, and ensure inclusive stakeholder engagement in climate planning.

The document details a screening methodology to assess the joint vulnerability of 35 U.S. coastal counties by combining socioeconomic data and climate projections. It utilizes a linear scaling technique to normalize variables—including per-capita income, poverty rates, and projected sea level rise—into composite risk indicators. The analysis incorporates historical damage data from SHELDUS and storm surge modeling for specific case studies to identify areas of high vulnerability.

The Union of Concerned Scientists finds that significant portions of the U.S. East and Gulf Coast electricity grids are currently exposed to coastal flooding, a risk that will increase as sea levels rise. In the central Gulf Coast specifically, 188 major substations and 20 power plants are currently at risk from a major storm. The report argues that relying on historical flood data is insufficient and recommends a combination of infrastructure adaptation (protection, accommodation, and retreat) and the deployment of decentralized clean energy solutions—such as microgrids and solar with storage—to ensure community resilience and reduce the carbon emissions driving sea level rise.

The report finds that significant portions of the U.S. East and Gulf Coast electricity grids are exposed to coastal flooding, with the Delaware Valley specifically facing risks to 79 substations and 35 power plants under current Category 3 hurricane conditions. It warns that reliance on historical flood data underestimates future risks as sea levels rise, potentially leading to widespread, long-lasting power outages. To address this, the authors recommend a combination of infrastructure adaptation (protection, accommodation, and retreat) and the deployment of decentralized clean energy technologies—such as solar with storage, combined heat and power (CHP) plants, and microgrids—to ensure critical facilities remain powered during grid failures while reducing the carbon emissions that drive sea level rise.

The report examines how rising sea levels and storm surges threaten critical electricity infrastructure, such as substations and power plants, in five major U.S. coastal regions. It finds that significant portions of the grid are already exposed to flooding, which can lead to widespread and prolonged power outages. The authors argue that current planning relies on outdated historical data and recommend a shift toward decentralized, resilient clean energy systems—including microgrids, energy storage, and combined heat and power plants—alongside infrastructure adaptation strategies like protection, accommodation, and retreat.

The Union of Concerned Scientists finds that significant electricity infrastructure along the U.S. East and Gulf Coasts is currently exposed to storm surge, a risk that will increase with sea level rise. In the South Carolina Lowcountry, 54 major substations and seven power plants are currently at risk. The report advocates for adaptation strategies—protection, accommodation, and retreat—and the deployment of decentralized clean energy technologies like microgrids and energy storage to ensure community resilience and reduce carbon emissions.

The Union of Concerned Scientists finds that significant portions of the U.S. East and Gulf Coast electricity grids are exposed to storm surge, a risk that will increase as sea levels rise. In southeastern Florida, the number of major substations at risk from a Category 3 storm is projected to triple by 2070. The report advocates for a shift from centralized grids to decentralized, resilient power systems—such as microgrids and renewable energy with storage—to protect critical facilities and reduce carbon emissions.

The report finds that significant portions of the U.S. East and Gulf Coast electricity grids are currently exposed to storm surge, with risks increasing as sea levels rise. In southeastern Virginia, 43 percent of major substations and four power plants are at risk today. The authors advocate for a shift from centralized grids to decentralized, resilient power systems—including microgrids and renewable energy with storage—to maintain critical services during outages and reduce the carbon emissions driving climate change.

The document describes the methodology for assessing the exposure of power plants and substations to flooding under a Category 3 hurricane scenario across five U.S. coastal regions. It utilizes the National Climate Assessment's Intermediate-High sea level rise scenario and the SLOSH model for storm surge, projecting risks through 2070. The analysis identifies a growing number of 'exposed' facilities, particularly in the Central Gulf Coast and Southeastern Florida, while noting limitations such as the exclusion of small distribution-level substations and the potential for local flood protection measures to mitigate risk.

The document examines climate vulnerability in the Soufriere region of Saint Lucia, identifying significant gaps in financial, human, and social capital that hinder adaptation. It highlights barriers such as top-down government planning and a lack of incentives in the tourism sector, while suggesting micro-insurance as a tool to replace high-stress coping mechanisms among the poor.

The report identifies five segments of coastal Connecticut residents: the First Out, Constrained, Optimists, Reluctant, and Diehards. These groups vary significantly in their perceived risk, actual preparedness, and likelihood of evacuating. While the First Out are the most anxious and likely to leave, the Diehards are the most self-reliant and least likely to evacuate. The analysis highlights that official orders from local police or fire departments are the most effective triggers for evacuation across all groups, though barriers such as pets, health issues, and financial constraints significantly hinder the Constrained and Optimists.
