The City of Norfolk is using an integrative process of planning, preparing, mitigating, and communicating to reduce the impacts of flooding. Working with international and regional experts and residents, Norfolk is creating planning models to predict future shoreline conditions. The models will predict how local rates of sea level rise affect the construction of public buildings, shipyards, naval facilities, homes, and other private development.
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..
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.

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 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.
Climate change is making the Arctic a greener, warmer, and increasingly accessible place for economic opportunity.

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.
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 was designed to Identify how beachgoers perceive the risk of dangerous currents and waves in the Great Lakes; evaluate existing messages and delivery mechanisms (such as National Weather Service Surf Zone Forecasts); translate complex beach conditions into understandable, actionable messages for specific beachgoer audiences; and identify effective delivery mechanisms for specific audiences.
As with the rest of the world and the Caribbean region in particular, the coastal and marine communities of the US Virgin Islands (USVI) are susceptible to the effects of climate change. Hazards include increasingly hazardous coastal conditions and loss of life-sustaining marine, coastal, and island resources. Climate change is anticipated to add to the stresses of the coastal environment by altering temperature and precipitation patterns, increasing the likelihood of extreme precipitation events, and accelerating rates of sea level rise.
Responding and adapting to such changes requires an understanding of the risks; weighing options for adapting to changing conditions; and instituting a suite of strategies to implement, measure, and fund response actions having the most benefits to the ecosystems and communities that depend on those services. With support from National Oceanic and Atmospheric Administration’s (NOAA) Coral Reef Conservation Program, The Nature Conservancy’s (TNC) Caribbean Program directed a project with the objective of developing decision-support tools and conservation strategies that will advance the implementation of ecosystem-based adaptation (EBA) to climate change within the USVI.
