This report reviews the coastal risk-reduction strategies and levels of protection that have been used along the United States East and Gulf Coasts to reduce the impacts of coastal flooding associated with storm surges. It evaluates their effectiveness in terms of economic return, protection of life safety, and minimization of environmental effects. According to the report, the vast majority of the funding for coastal risk-related issues is provided only after a disaster occurs. The report calls for the development of a national vision for coastal risk management that includes a long-term view, regional solutions, and recognition of the full array of economic, social, environmental, and life-safety benefits that come from risk reduction efforts.
This technical report looks at more than 60 years of coastal water level and local elevation data, analyzing sea level rise and nuisance flood frequency changes around the United States.
This plan evaluates the risks that different hazards pose to Berkeley and engages the community in dialogue to identify the most important steps that the city and its partners should pursue to reduce these risks. The plan updates the city's plan initially adopted in 2004. To develop the 2004 Disaster Mitigation Plan, the city conducted detailed research on four major natural and two major “man-made” hazards present in Berkeley: earthquake, wildland-urban interface fire, landslide, flood, hazardous materials release, and terrorism. Since that time, new maps and data depicting the extent and possible impacts from tsunami and climate change have become available. In 2011, the city added these hazards to the list and they are incorporated into this plan..

The report was extensively reviewed by the public and experts, including a panel of the National Academy of Sciences, the 13 federal agencies of the U.S. Global Change Research Program, and the Federal Committee on Environment, Natural Resources, and Sustainability.
On September 27, 2006, then-Governor Arnold Schwarzenegger signed California's Global Warming Solutions Act of 2006, which required the reduction of greenhouse gas emissions to 1990 levels by 2020. The California Air Resources Board is the lead agency for implementing the bill. One of the board's tasks was to create a scoping plan that would outline California’s strategy to achieve the 2020 greenhouse gas emission goal. This current scoping plan is an update from the original version, published in 2008. In addition to updates, this plan also contains progress reports on how California is progressing towards its goals.
This report looks at how climate change is affecting the nation’s wildlife and habitats, and addresses how natural resource managers need to prepare for and adapt to these unprecedented changes.
Climate change is making the Arctic a greener, warmer, and increasingly accessible place for economic opportunity. However, climate impacts such as sea ice loss and rising ocean acidification are straining coastal community resilience and sound resource stewardship. NOAA's Arctic Action Plan outlines ways for scientists and stakeholders to share their progress regarding this vast, valuable, and vulnerable region.
This report focuses on livestock diseases that are sensitive to climate change. The report aims to help practitioners reduce the risks of key climate-sensitive infectious diseases by strengthening risk management systems for disease outbreaks. The three diseases chosen for the study—Rift Valley fever, Bluetongue, and East Coast fever—spread through “vectors” such as insects and parasites, the prevalence of which fluctuates depending on key weather and climate variables such as temperature and humidity. As the symptoms of climate change continue, the frequency and extent of these diseases are expected to escalate.
This Fifth Assessment Report issued by the Intergovernmental Panel on Climate Change (IPCC) Working Group III is a comprehensive assessment by of all relevant options for mitigating climate change through limiting or preventing greenhouse gas emissions, as well as activities that remove them from the atmosphere.
In April 2014, the National Park Service (NPS) convened a select group of leaders in the fields of planning, architecture, landscape architecture, historic preservation, archeology, science, and park and cultural resource management to participate in a planning session entitled Preserving Coastal Heritage. This summary report provides the recommendations and feedback that emerged over the course of the two-day work session, along with highlights from the presentations and remarks. Case studies include four sites in New York and New Jersey. The Preserving Coastal Heritage work session was part of an NPS effort to develop a cultural resources climate change response strategy.
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.
In anticipation of rising sea levels, a team worked to to gauge the impact of rising tides on local communities and infrastructure. This report describes the process and outcomes of efforts to protect at-risk assets through proactive planning and early identification of adaptation measures.
