These guidelines—which include climate change and sea level rise considerations—were developed to provide a comprehensive framework for site assessment and alternatives analysis to determine the need for shore protection and identify the technique that best suits the conditions at a given site. There are many guidelines and manuals for the design of "protection" techniques for the more typical open coast, but prior to the Marine Shoreline Design Guidelines (MSDG) there was almost no guidance that reflected the variety of conditions found in Puget Sound. For this reason, the MSDG were created to inform responsible management of Puget Sound shores for the benefit of landowners and shared natural resources.
This report describes a community-driven project built on efforts by Shaktoolik and other at-risk, mainly Alaska Native villages on the Bering Sea coast to adapt to potentially devastating effects of climate change. The project involved a multi-party approach to assist the community of Shaktoolik to make a decision whether to relocate or stay at the current location. The result is a well-defined process that may be replicated by other at-risk communities in the region. The final report documents lessons learned, adaptation methods for Shaktoolik, potential funding sources, and a step-by-step action plan to implement the community's decision.

The Sacramento-San Joaquin River Delta is the grand confluence of California’s waters, the place where the state’s largest rivers merge in a web of channels—and in a maze of controversy. In 2009, seeking an end to decades of conflict over water, the California Legislature established the Delta Stewardship Council with a mandate to resolve long-standing issues. The first step toward that resolution is the Delta Plan—a comprehensive management plan for California’s Sacramento-San Joaquin Delta, developed to guide state and local agencies to help achieve the co-equal goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the delta's ecosystem.
This plan looks at strategies for incorporating climate change resilience throughout New York's entire transportation system.
Coastal areas are especially vulnerable to hazards, now and in the future, posed by waves and surges associated with sea level change and coastal storms. Coastal risk reduction can be achieved through a variety of approaches, including natural or nature-based features (e.g., wetlands and dunes), nonstructural interventions (e.g., policies, building codes, and emergency response such as early warning and evacuation plans), and structural interventions (e.g., seawalls and breakwaters). This report discusses the U.S. Army Corps of Engineers' capabilities to help reduce risks to coastal areas and improve resilience to coastal hazards through an integrated planning approach.
This report, representing the Intergovernmental Panel on Climate Change (IPCC) Working Group I's contribution to the IPCC Fifth Assessment report (AR5), explores the hard science elements of global climate change.
