Sea Level Rise Could Double Erosion Rates of Southern California Coastal Cliffs

Coastal cliffs from Santa Barbara to San Diego might crumble at more than twice the historical rate by the year 2100 as sea levels rise. U.S. Geological Survey scientists combined several computer models for the first time to forecast cliff erosion along the Southern California coast.

Scientists have discovered that the seafloor from the Mississippi River Delta to the Gulf of Mexico is eroding like the land loss that is occurring on the Louisiana coast. During the 20th century, thousands of dams were built on Mississippi River tributaries stopping the flow of fine silt, clay and other sediment from reaching the delta and seafloor to offset erosion.
