Can California’s coastline be saved? Study shows up to 70% could be wiped out by 2100

In the not too distant future, California’s coastline and its iconic beaches could be washed away, leaving only cliffs behind.

A new U.S. Geological Survey study found from 25% to 70% of California’s beaches could erode by 2100 due to rising sea levels caused by global temperature increases and greenhouse gas emissions. Substantial management efforts like dune restoration are necessary to maintain the beaches and prevent catastrophic erosion, the authors of the study said.
