O'ahu's shores could see heavy erosion by 2030, study finds

O'ahu's sandy beaches are at risk. New research from the Coastal Research Collaborative (CRC) at the University of Hawai'i (UH) at Mānoa determined that 81% of O'ahu's coastline could experience erosion by 2100, with 40% of this loss happening by 2030. Importantly, these forecasts of shoreline erosion are more extreme than previous studies indicated for Oʻahu. The study was published recently in Scientific Reports.
