Council, Ocean Protection. “State of California Sea Level Rise Guidance, 2018 Update.” Ocean Protection Council: Sacramento, CA, USA (2018): 84.
This updated document, the “State of California Sea-Level Rise Guidance” (Guidance), provides a bold, science-based methodology for state and local governments to analyze and assess the risks associated with sea-level rise, and to incorporate sea-level rise into their planning, permitting, and investment decisions. This Guidance provides:
1. A synthesis of the best available science on sea-level rise projections and rates for California;
2. A step-by-step approach for state agencies and local governments to evaluate those projections and related hazard information in decision making; and
3. Preferred coastal adaptation approaches
California’s Fourth Climate Change Assessment – Statewide Summary (2018)
The Statewide Summary Report presents an overview of the main findings from California’s Fourth Climate Change Assessment, to translate the state of climate science into useful information for action. This report presents findings in the context of existing climate science, including strategies to adapt to climate impacts and key research gaps needed to spur additional progress on safeguarding California from climate change.

California’s Changing Climate 2018: A Summary of Key Findings from California’s Fourth Climate Change Assessment
California’s Fourth Climate Change Assessment provides information to build resilience to climate impacts, including temperature, wildfire, water, sea level rise, and governance. Here you can view a snapshot of the key findings of the Fourth Assessment. For additional information, please download the Key Findings brochure.
ASSESSING AND COMMUNICATING THE IMPACTS OF CLIMATE CHANGE ON THE SOUTHERN CALIFORNIA COAST (2018)
Over the course of this and the next century, the combination of rising sea levels, severe storms, and coastal erosion will threaten the sustainability of coastal communities, development, and ecosystems as we currently know them. To clearly identify coastal vulnerabilities and develop appropriate adaptation strategies for projected increased levels of coastal flooding and erosion, coastal managers need user-friendly planning tools based on the best available climate and coastal science. In anticipation of these climate change impacts, many communities are in the early stages of climate change adaptation planning but lack the scientific information and tools to adequately address the potential impacts. In collaboration with leading scientists worldwide, the USGS designed the Coastal Storm Modeling System (CoSMoS) to assess the coastal impacts of climate change for the California coast, including the combination of sea level rise, storms, and coastal change. In this project, we directly address the needs of coastal resource managers in Southern California by integrating a vast range of global climate change projections and translate that information using sophisticated physical process models into planning-scale physical, ecological, and economic exposure, shoreline change, and impact assessments, all delivered in two simple, user-friendly, online tools. Our results show that by the end of the 21st century, over 250,000 residents and nearly $40 billion in building value across Southern California could be exposed to coastal flooding from storms, sea level rise, and coastal change. Results for the other major population center in California (the greater San Francisco Bay Area) are also available but not explicitly discussed in this report. Together, CoSMoS has now assessed the exposure of 95% of the 26 million coastal residents of the State (17 million in Southern California).
