A new study uses satellites to predict what California’s famous coastline could look like by 2100
California is known for golden sands and endless waves, but much of the state’s famous shoreline could vanish in the future. That’s according to a new study, which found that between 25% and 70% of California beaches might be washed away by the end of the century, leaving only cliffs or coastal infrastructure in their wake.
The study used satellite data collected over the past two decades to examine California’s 1,100-mile-long coast. Researchers from the US Geological Survey (USGS) used those satellite images, combined with models of climate crisis-driven sea level rise ranging from 1.6 to 10ft, to estimate the shape and position of the state’s coastline by 2100. The amount of sea level rise will depend on how much carbon is pumped into the atmosphere now and in the future.
