Extreme weather and climate events pose significant risks to rural water and wastewater systems. We examine the vulnerability of the water sector to weather and climate extremes in rural, predominantly Indigenous and underserved coastal areas and analyze how networks support resilience. Drawing on the analysis of 39 web‐based questionnaire responses and 19 interviews with rural water and wastewater managers and service providers in southern Louisiana and western Alaska, this article reports a range of interrelated historical, environmental, and social factors that influence vulnerability to extreme weather events. Formal and informal social networks serve multiple roles in building resilience. These roles include building technical and financial capacities, supporting emergency response and operational‐ to long‐term planning, fostering data collection and monitoring, supporting information sharing and innovative research, and providing institutional support. Results from this research enrich our understanding of the social, relational, and networking processes that condition community resilience to extreme weather events. [ABSTRACT FROM AUTHOR]

Understanding how to design climate services across a range of contexts remains a key priority. This research evaluates the Sea Ice for Walrus Outlook (SIWO), a resource designed to provide information about sea ice, weather, and walruses in Alaska, a region experiencing rapid social and environmental change. The evaluation was based on a set of 22 indicators developed from literature on evaluation, weather and climate services, science communication, and decision support. Two datasets were assessed to evaluate the SIWO: semi-structured interviews (n = 13) and a web-based questionnaire (n = 35). Interpretation of the outcome indicators suggests that the SIWO supported several community needs, including providing information to support travel, documenting historical impacts for disaster relief, and sharing Indigenous Knowledge among villages. The evaluation revealed insights into the kinds of information useful for rural and Indigenous communities, such as the importance of local observations from within and from nearby villages. Recommendations for other emergent organizations providing climate services in rural communities include attention to specific budget considerations to support equitable engagement and compensation, including both local and scientific observations, using multiple channels to disseminate information, and including evaluations in the design of climate services that are aligned with funding cycles.

Understanding potential risks, vulnerabilities, and impacts to weather extremes and climate change are key information needs for coastal planners and managers in support of climate adaptation. Assessing historical trends and potential socio-economic impacts is especially difficult in the Arctic given limitations on availability of weather observations and historical impacts. This study utilizes a novel interdisciplinary approach that integrates archival analysis, observational data, and climate model downscaling to synthesize information on historical and projected impacts of extreme weather events in Nome, Alaska. Over 300 impacts (1990–2018) are identified based on analyses of the Nome Nugget newspaper articles and Storm Data entries. Historical impacts centered on transportation, community activities, and utilities. Analysis of observed and ERA5 reanalysis data indicates that impacts are frequently associated with high wind, extreme low temperatures, heavy snowfall events, and winter days above freezing. Downscaled output (2020–2100) from two climate models suggests that there will be changes in the frequency and timing of these extreme weather events. For example, extreme cold temperature is projected to decrease through the 2040s and then rarely occurs afterwards, and extreme wind events show little change before the 2070s. Significantly, our findings also reveal that not all weather-related extremes will change monotonically throughout the twenty-first century, such as extreme snowfall events that will increase through the 2030s before declining in the 2040s. The dynamical nature of projected changes in extreme events has implications for climate adaptation planning. [ABSTRACT FROM AUTHOR]

Changing biophysical conditions due to amplified climate change in northern latitudes has significant implications for species' habitat and populations and can dramatically alter interactions between harvesters and local resources. Tribal, regional, and state governments, federal agencies, and other local planning entities have begun documenting observations of changing harvest conditions and the information necessary for communities to adapt to shifting resource availability. We identify and evaluate what stakeholders are saying about wild foods in the context of climate change information needs in Alaska through a review of published grey literature (n = 87). Documents consistently expressed that climate change was impacting habitat conditions, resource distribution, and the abundance of wild foods. They solicited more information on biophysical processes (e.g., sea ice conditions) and populationlevel responses (e.g., shift in migration patterns). They also recommended that future projects focus on information that will improve food security, travel access, and community well-being. Documents suggested that communities have successfully sustained harvest practices, but most current adaptations are localized decisions being made by harvesters to manage the risks of current climate change. Strategies include finding new areas to hunt, substituting harvest species with other wild foods, or using new modes of travel. Documents also identified several adaptation strategies that still need to be implemented, and are dependent on actions by actors at larger scales; these strategies include legal, policy, and management actions to help reduce climate change impacts to wild food harvest. This review of the grey literature complements the climate-change literature by describing information needs of Alaskan wild food harvesters as well as providing tangible suggestions about how to improve adaptation and management strategies for harvesters grappling with changing resource conditions in the Arctic.
