New York State's affordable housing stock is the second most vulnerable in the nation, with 5,293 units projected to be at risk by 2050, representing a 236% increase from current levels.

The document highlights that New York City has the highest number of affordable housing units at risk of coastal flooding in the United States. By 2050, the number of units at risk in New York City is projected to increase by 248% to 4,774 units. New York State as a whole is the second most vulnerable state in the nation, with 5,293 units projected to be at risk by 2050, representing a 236% increase from current levels.

The document highlights that Virginia's affordable housing stock is the 4th most vulnerable in the United States to future coastal flooding. By 2050, 1,473 units in Virginia are projected to be at risk, representing a 273% increase from current levels. Norfolk and Portsmouth are specifically identified as high-risk cities, with Norfolk ranking 5th and Portsmouth 17th nationwide for the percentage of affordable housing supply exposed in 2050.

The document reports that Virginia's affordable housing supply is the fourth most vulnerable in the United States to future coastal flooding. By 2050, 1,473 affordable housing units in Virginia are projected to be at risk, representing a 273% increase from current levels. The cities of Norfolk and Portsmouth are highlighted as particularly vulnerable, with projected increases in exposed units of 523% and 610% respectively.

The report examines how sea level rise and coastal flooding threaten elderly populations in the U.S., particularly those in nursing homes and assisted living facilities. It highlights the dangers of evacuation for frail seniors, the impact of 'sunny day' flooding on access to healthcare, and the hidden financial risks to real estate equity for retirees on fixed incomes.

The Pacific Islands Climate Storybook 2021 outlines a methodology for 'Climate Services Dialogs'—three-day workshops designed to bridge the gap between scientific climate data and local experiential knowledge. The process involves sharing climate knowledge, diagnosing existing services using the 'READY-SET-GO' framework, and developing 'Climate Stories' to communicate best practices. The report includes several case studies from the region, such as the impact of the 1997–98 El Niño on water resources in American Sāmoa, coastal flooding in Papua New Guinea and the Marshall Islands, and the link between drought and disease outbreaks in the Marshall Islands. It emphasizes the need for co-production of knowledge, community engagement, and the integration of traditional knowledge with scientific forecasts to enhance regional resilience.

The document reports that while the total number of hurricanes is not increasing, the probability of storms reaching major hurricane status (Category 3-5) has risen significantly, particularly in the North Atlantic. It attributes this trend to rising sea surface temperatures and atmospheric warming, which also contribute to heavier rainfall, slower storm speeds, and deeper coastal flooding due to sea level rise.

The document describes a two-part methodology: first, using a "bathtub model" combining Digital Elevation Models, tidal gauge data, and NOAA sea level rise projections to map future 100-year-flood zones; second, performing a buffer analysis around 9,689 Superfund sites to determine if people of color and low-income households are disproportionately located near sites at risk of flooding.

The document emphasizes that local policymakers struggle to act on climate information that is not location-specific. To address this, Climate Central provides two tools: the Coastal Risk Screening Tool, which allows users to explore coastal flood and sea-level rise risk by year or water level, and Risk Finder, which provides data on at-risk populations and facilities for states, counties, and Congressional districts. These tools utilize data from approximately 110 databases, including various U.S. federal agencies such as NOAA, USGS, and FEMA.

The document describes a vulnerability assessment protocol developed for the National Park Service (NPS) to evaluate coastal infrastructure risks. The assessments focus on physical exposure and characteristics, helping managers decide whether to protect, move, or decommission assets. While sea level rise models projected to 2050 are used, the text notes that hurricanes at current sea levels contribute significantly to exposure scores. Practical applications include raising utilities in Florida and incorporating local perspectives at Cumberland Island National Seashore.

Washington Sea Grant developed a localized sea level rise assessment for Washington State to bridge the 'action gap' between the perceived importance of climate impacts and the availability of planning tools. The project introduced a probabilistic framework for communicating uncertainty and integrated vertical land movement data to create site-specific relative sea-level projections. These data were delivered via an interactive map and a Tableau-based tool. Implementation efforts included pilot projects in Tacoma and Island County, where the data informed the redesign of Owen Beach, the visioning of a linear park, and the creation of a community-based coastal resilience planning guide for shoreline homeowners.

The briefing describes a multi-year project to assess the vulnerability of National Park Service (NPS) coastal assets to hazards such as sea level rise and storm surges. The methodology separates vulnerability into 'exposure' (the likelihood of a hazard hitting an asset) and 'sensitivity' (the potential damage once the hazard occurs). By integrating this data into existing asset management databases, the project provides park managers with a science-based menu of adaptation options—such as elevating, relocating, or decommissioning structures—to optimize the allocation of limited maintenance funds based on an asset's mission priority.

The briefing describes the development and application of a customized vulnerability assessment and inundation mapping tool for New York's Great Lakes region. It emphasizes the importance of using 'weather trends' rather than 'climate change' terminology to engage local officials and highlights a case study in the village of Sodus Point where participatory workshops led to specific resiliency actions, such as new communication strategies and the investigation of the Coastal Erosion Hazard Act.
