If state projections prove right, the sea level along California’s coast will rise 55 inches by the end of this century. That increase, which will be even higher during tidal floods and Pacific storms, would threaten the economies of the coastal counties that 85 percent of Californians call home. And it could spell doom for water sources, major roadways, hazardous waste facilities, military installations, power plants, airports, and seaports. How will this sea level rise change coastal communities, coastal industries from fish to oil, and postcard settings from Big Sur to San Diego? What can be done to mitigate the effects of rising seas and save California treasures? Or will California have to abandon many of its coastal and low-lying areas? Atmospheric physicist and director of the UCLA Center for Climate Science Alex Hall, California Coastal Commission member Effie Turnbull Sanders, and Sean B. Hecht, co-executive director of the Emmett Institute on Climate Change and the Environment at the UCLA School of Law, visit Zócalo to detail the extent to which California could lose its signature coastline.
