This guide is designed to help transportation practitioners understand how and where nature-based and hybrid solutions can be used to improve the resilience of coastal roads and bridges. It summarizes the potential flood-reduction benefits and co-benefits of these strategies, then follows the steps in the project delivery process, providing guidance on considering nature-based solutions in the planning process, conducting site assessments, key engineering and ecological design considerations, permitting approaches, construction considerations, and monitoring and maintenance strategies. The guide also includes appendices with site characterization tools, decision support for selecting nature-based solutions, suggested performance metrics, and links to additional tools and resources.
An intensified pattern of wildfire is emerging in Alaska as rapidly increasing temperatures and longer growing seasons alter the state's environment. This publication aims to convey the rapidly changing patterns of wildfire in Alaska by looking into the phases of fire. Patterns emerging in the 21st century are the primary focus, with earlier histories of management, climate, and fire being drawn upon for context.
Each region of the United States experiences climate change and its impacts on health differently, due to the regions’ location-specific climate exposures and unique societal and demographic characteristics. This document describes the various health impacts climate change will have on different regions of the United States as outlined in the Fourth National Climate Assessment (NCA4), actions taken by the CDC Climate and Health Program’s health department partners to prepare for and respond to climate change in their communities, and relevant tools and resources.
Climate migration—the preemptive movement of people and property away from areas experiencing severe impacts—is one way to improve climate resilience. This report reviews federal support for climate migration, examining the use of climate migration as a resilience strategy, federal support for climate migration, key challenges to climate migration, and how the federal government can address them. A literature review and interviews with climate resilience experts was conducted, with 46 stakeholders selected and interviewed in four communities that have considered relocation: Newtok, Alaska; Santa Rosa, California; Isle de Jean Charles, Louisiana; and Smith Island, Maryland.
Arctic ecosystems and communities are increasingly at risk due to continued warming and declining sea ice. The Arctic marine ecosystem and the communities that depend upon it continue to experience unprecedented changes as a result of warming air temperatures, declining sea ice, and warming waters. This 2019 update to the Arctic Report Card draws particular attention to the Bering Sea region, where declining winter sea ice exemplifies the potential for sudden and extreme change. Indigenous Elders from the Bering Sea region offer their experiences of living at the forefront of climate change.
