Coastal communities around the world face increasing threats from storm surges—intense rises in sea level caused by powerful storms pushing water ashore. A new study using advanced statistical modeling and historical sea-level observational data shows that the likelihood of these extreme events occurring is much higher than previously estimated, raising concerns about future coastal flood risks.
