Sea level rise can make hurricanes more damaging to barrier islands. A study used a computer model to see how future sea levels affect storm surges and island shape. Higher sea levels made storm surges bigger and caused more flooding on the islands. After the storm, water movements carried sand away from the islands. With higher sea levels, more sand was lost from the islands, making them shrink faster. Understanding how sea level rise affects storms and islands is crucial for managing coastal areas in the long run.
