Southern California beaches could suffer unprecedented erosion: Study

Southern California beaches to suffer unprecedented erosion

California is one of the places where many beaches would likely completely erode by 2100 as global warming continues to push sea levels up, a new study by the U.S. Geological Survey (USGS) has warned.

According to the USGS, California could find anywhere between a third to two-thirds of its beaches in the southern part completely eroded by the end of this century.

The federal agency said in a statement, “With limited human intervention, 31 to 67 percent of Southern California beaches may become completely eroded (up to existing coastal infrastructure or sea-cliffs) by the year 2100 under scenarios of sea-level rise of one to two meters.”

Scientists reached the conclusion after using a newly-developed computer model dubbed Coastal Storm Modeling System – Coastal One-line Assimilated Simulation Tool (CoSMoS-COAST).

As per the National Oceanic & Atmospheric Administration, the average global sea level was 2.6-inch higher in 2014 than the average recorded in 1993, and sea levels keep on rising at an average of around 1/8th of an inch every year.

The effect of beach erosion isn’t just a matter of affecting a state’s tourism economy. Losing the defensive swath of beach sand between human settlements and the throbbing surf exposes businesses, homes and other critical infrastructure to damage.
