Most Southern California Beaches Could Erode By 2100 Without Human Intervention, Study Finds

Rising seas are eating away at ocean-front sand at a pace that could leave Southern California with few usable beaches by the end of this century, scientists announced Monday. Research based on information from the U.S. Geological Survey’s newly created computer model, the Coastal Storm Modeling System, shows that with little human intervention up to 67 percent of the beaches in Southern California could erode completely in less than 100 years, according to a paper published in the Journal of Geophysical Research.
