California is already feeling the impacts of climate change. Coastal communities across the state are experiencing the effects of sea-level rise, including high tides, strong storm surges, coastal flooding, sand erosion, and bluff collapses. California's coastline could experience as much as 7 feet of sea-level rise by 2100, which will have extensive and expensive impacts on the state's residents, economy, and natural resources. Most responsibility for preparing for and responding to these threats lies with local coastal communities. Yet despite the significant threats and compelling reasons to take action now, many coastal communities still are only in the early stages of preparing for sea-level rise.
