Hawai’i's Oahu sinking faster than predicted, urgent action needed

New research shows that parts of Hawai’i are sinking much faster than previously thought. A study from the University of Hawai’i at Mānoa finds that areas on the island of Oahu are sinking 40 times quicker than experts predicted. The study, published in the journal Communications Earth & Environment, highlights that low-lying urban areas are most at risk. These regions are more prone to flooding due to rising sea levels. Researchers have noted various impacts already, such as beach loss, coastal erosion, and flooding from heavy rains. Lead author Kyle Murray warns that the effects of sea level rise will occur sooner than expected. This means Hawai’i needs to prepare for flooding much earlier than previously planned. The study estimates that over $12.9 billion in infrastructure on O'ahu could be at risk from flooding. Popular tourist spots like Honolulu and Waikiki may see significant flooding in the coming decades. Experts warn that the likelihood of flooding in some areas could increase by over 50 percent by 2050. The research aims to help local governments make better decisions about flood preparedness and infrastructure. Co-author Chip Fletcher emphasizes that the findings will aid in developing smart adaptation strategies to protect homes and businesses in Hawai’i.
