Confronting Shoreline Erosion on Oahu

Hawaii Sea Grant's work featured in U.S. Climate Resilience Toolkit

Each winter, massive waves attract surfers and visitors to the North Shore of O‘ahu in Hawai‘i. Some years, the waves cause severe erosion, and continuing sea level rise will accelerate this issue. Residents and the state are taking steps to preserve homes and beaches.
