Scientists say that half of the world's sandy beached are at risk of disappearing by the end of the century if climate changes continues unchecked.
The study, published Monday in the journal Nature Climate Change, found that the extent to which beaches are at risk depends on how much average global temperatures increase by the year 2100. Greater temperature increases mean more sea level rise and more violent storms in some regions, causing more beaches to vanish beneath the waves.
Many coastal areas, including beaches, are already heavily affected by human activity such as seashore construction and inland dams, which reduce the amount of silt flowing into oceans that's crucial for beach recovery. Story continuesAndres Payo, an expert on coastal hazards and resilience at the British Geological Survey, said that while the study's methods were sound, its claims should be treated with caution.
