Southern California beaches facing severe damage due to rising sea levels: USGS

Rising sea levels will severely damage 31 to 67 per cent of Southern California beaches by the end of this century, according to a new study.

The U.S. Geological Survey (USGS) warned in the newly published study that Southern California is one of the many places where several beaches would likely fully erode by 2100 as global warming keep on pushing sea levels up.

Study lead author Sean Vitousek said, “Beaches are perhaps the most iconic feature of California, and the potential for losing this identity is real. The effect of California losing its beaches is not just a matter of affecting the tourism economy.”

The scientists applied a special shoreline change computer model called Coastal Storm Modeling System – Coastal One-line Assimilated Simulation Tool (CoSMoS-COAST) to estimate coastal hazard assessment as well as management planning in the future.

Erosion of beaches will not only affect California’s tourism economy, but also result in loss of the defensive swath of beach sand that protects businesses, homes and other critical infrastructure from throbbing surfs.

The findings of the new study were detailed in the most recent edition of the American Geophysical Union’s Journal of Geophysical Research.
