Where's the Beach?

Erosion along US oceanic coasts is expected to increase in a changing climate due to an increase in sea level rise, heavy precipitation events, flooding, and storm surges. The more populated areas, which are along the Gulf of Mexico, Mid-Atantic, northern Alaska, Hawaii, and island territories, are more susceptible to coastal erosion due to their low-lying elevation. For example, relative sea level rise along coastal Louisiana has increased by eight inches or more in the last 50 years, slightly faster than twice the global rate, increasing their risk of erosion. 

Coastal oceanic erosion can cause beaches and costal buffers such as dunes to wear away, which can be bad news for homes, infrastructure, beachgoers, and wildlife. For example, it is estimated that erosion is responsible for around $500 million in coastal property loss each year. Along the coast of Florida, sea level has risen seven to inches inches over the past century. An additional one foot would erode most Florida beaches 100 to 200 feet without the adoption of adaptation measures to hold back the sea.
