Climate change is expected to disrupt many aspects of life in American Sāmoa. Those who are already vulnerable—including children, the elderly, low-income families, and individuals with disabilities—are at greater risk from extreme weather and climate events. Climate Change in American Sāmoa: Indicators and Considerations for Key Sectors provides guidance for decision-makers seeking to better understand the implications of climate variability and change for American Sāmoa and its communities. This assessment also identifies the additional information and research needed to support responses that enhance resilience and help American Sāmoa to withstand the changes to come.

The report is one of a series of PIRCA reports aimed at assessing the state of knowledge about climate change indicators, impacts, and adaptive capacity of the US-Affiliated Pacific Islands and the Hawaiian archipelago. Authors from the University of Hawai‘i and the East-West Center—along with 25 technical contributors from local governments, NGOs, researchers, and community groups—collaboratively developed the American Sāmoa report.

This report's subtitle is Managing the Uncertainty of Future Sea Level Change and Extreme Water Levels for Department of Defence Coastal Sites Worldwide.

From the Executive Summary: Global change, including climate change, poses unique challenges to the Department of Defense (DoD). In particular, coastal military sites, and their associated natural and built infrastructure, operations, and readiness capabilities, are vulnerable to the impacts of rising global sea level and local extreme water level (EWL) events. This report and its accompanying scenario database provide regionalized sea level and EWL scenarios for three future time horizons (2035, 2065, and 2100) for 1,774 DoD sites worldwide. The global nature of DoD’s presence required a broad and comprehensive approach that to this point has been lacking in similar efforts.

Planning for climate change resiliency is an increasingly pressing requirement for communities throughout the world and the Delaware Valley Regional Planning Commission (DVRPC) region. In order to help local officials, non-profits, and communities with this process, numerous planning tools have been developed by a wide range of public and private agencies. Accordingly, the purpose of this paper is to explain, organize, and prioritize the tools that currently exist in order to select ones that are broadly accessible to a wide range of organizations, applicable across a range of sectors, and not overly redundant. During this selection process, a list of over 60 tools was winnowed down to a final toolkit of 18 that are particularly useful at any stage in the resiliency planning process and can be used for communities throughout the DVRPC region.

The Beloved Community is a vision for our future where all people share equally in the wealth and bounty of the earth, where we protect its abundance, diversity, and beauty for future generations. In this vision of liberation, racism, exploitation, and domination are replaced by democracy, cooperation, interdependence, and love. To get there, we pursue transformative, systems-change solutions. What do we mean by this? The root causes of the problems our communities face—like climate change, racism, and economic inequality—are all deeply connected. Since the problems are connected, so are the solutions. The purpose of this toolkit is to put us on the path toward achieving this vision. Through the context of building equity and resilience into climate adaptation planning, we introduce strategies to transform our communities and, by extension, society. Our ultimate goal is to create lasting and systemic change. At the same time, we recognize the urgency of the issues our communities face and the need to take action now. That is why we pursue change at every scale—from policy changes to community-based projects—to institute the transformative change we need to uphold our vision of the beloved community.

This analysis examines what's at risk for U.S. coastal real estate from sea level rise. Millions of Americans living in coastal communities will face more frequent and disruptive high-tide flooding; as this flooding increases, it will reach a threshold where normal routines become impossible and coastal residents, communities, and businesses are forced to make difficult, often costly choices. For this analysis, that threshold is defined as flooding that occurs 26 times per year (on average, once every other week) or more, a level of disruption referred to as chronic inundation. The results identify the number of residential and commercial properties at risk of chronic inundation—and the total current property value, estimated population, and property tax base affected—for the entire coastline of the lower 48 states.

This report describes a conceptual model of climate resilience, codified as an index. The Climate Resilience Screening Index (CRSI) is designed to be sensitive to changes in the natural environment, built environment, governance, and social structure and vulnerability or risk to climate events. CRSI has been used to develop an index score for climate resilience at the county level (scalable both upward and downward spatially). The index represents both the vulnerability of the entity to multiple climate events and the potential recoverability of these entities from climate events.

The approach uses five domainsand 20 indicators related to the domains. CRSI characterizes holistic climate resilience throughout the US at the county level (2000-2015); ascertains the relationships among those domains and indicators; and, provide information regarding how that resilience score is constructed and the actions a community/county can take to improve their climate resilience.

This assessment of seven priority hazards was undertaken by the Florida BRACE (Building Resilience Against Climate Effects) program. Existing climate scenarios project heat, drought, and sea level rise vulnerability to the year 2100 with a high, medium, and low range of outcomes for these three hazards. Hurricane winds, storm surge, flooding, and wildland fire are more difficult to project into the future due to a significantly smaller geographic impact; for these four hazards, probability indexes were used in conjunction with historical patterns to explain possible changes to Florida’s long-term weather. Social and medical vulnerability indices were also employed to quantify social and medical vulnerability to these priority hazards.

Climate Ready Boston is an ongoing initiative to help the people and city of Boston to plan for the future impacts of climate change and develop resilient solutions. Boston Mayor Martin J. Walsh describes the challenge and the city's commitment in the report's introduction: "Climate change poses a greater threat to some Bostonians. The very young and very old, people who do not speak English, and those with low incomes or medical illnesses or disabilities are all at elevated risk. By ensuring that our solutions are built together with those communities and in response to their needs, climate action will help us build a more equitable city. Furthermore, because climate change knows no borders, we will work with neighboring municipalities to address the regional impacts we face together." The Climate Ready Boston website offers proposed solutions and information specific to a range of locales. It also offers a presentation and report on Climate Change and Sea Level Rise Projections for Boston.

This Web toolkit raises airport operator awareness about vulnerabilities caused by significant weather events. The toolkit helps airports develop more robust contingency and recovery plans, in addition to their airport emergency plans. The toolkit focuses on events that are “rare but plausible”; that is, events that may have happened in the distant past, or in adjacent geographic areas, but are not common event types at the airport itself, and therefore may not be in the forefront of the airport managers’ minds.

This Health Impact Assessment was done in conjunction with the development of an adaptation plan, with the goal of ensuring that the strategies developed would be health-focused before implementation. By conducting the HIA during the Climate Change Adaptation Plan’s development, greater efficiencies were created in terms of addressing strategy-specific, health-related issues that could be avoided at the start, rather than discovering them after the strategies had already been implemented. This report is the culmination of the HIA process and summarizes each step of the assessment, including the HIA Project Team and Advisory Committee’s recommendations for improving the Climate Change Adaptation Plan. The adoption of these recommendations will increase the value relevance of the adaptation plan and benefit the health of the region.
