Over the next century, sea level rise in Southern California is expected to match global projections with an increase of 0.1-0.6 meters (5-24 inches) from 2000 to 2050 and 0.4-1.7 meters (17-66 inches) from 2000 to 2100. Rising seas, combined with the threat of other coastal impacts such as coastal erosion, high tides and severe storms, are driving coastal communities to begin planning for these challenges and identifying strategies to adapt. Results from the Coastal Storm Modeling System (CoSMoS) support numerous local municipalities who may use the findings to plan for climate change impacts, including adaptation planning, updating Local Coastal Plans per guidance from the State of California, and conducting risk assessments for local hazard mitigation plans.
Materials are now available from the recent workshop detailing final results from the USGS's Coastal Storm Modeling System (CoSMoS) for the San Diego region. Learn how to access and use this sea level rise forecasting tool by clicking here.
