By how much meters is the coast eroding each year?

The rate at which the coast erodes varies depending on the location and the specific environmental factors at play. While certain areas may experience minimal erosion, others can be subject to significant coastal retreat. Global estimates of coastal erosion rates range from 0.25 to 1.0 meters per year. However, some highly vulnerable areas, particularly in developing nations, can experience erosion rates exceeding several meters annually.
