While previous research has largely focused on flooding, the new study highlights additional threats such as groundwater hazards, land subsidence, and beach erosion. These hazards, often underappreciated in climate discussions, will be amplified by sea levels projected to rise by one meter over the next century. The study estimates that up to 70% of coastal residents and $1 trillion in property could face challenges from shallow and emerging groundwater. This risk is 15 times greater than the exposure to daily tidal flooding alone.
