"Rising Seas Threaten Major US Coastal Cities, Study Warns"

New research shows that 32 coastal cities in the US are at risk of flooding by 2050 due to land subsidence, exacerbating the impact of sea level rise. Major cities like Boston, New Orleans, and San Francisco are among those facing potential flooding, with up to 273,000 people and 171,000 properties at risk. Groundwater extraction and sediment compaction are driving the subsidence, and current hazard mitigation efforts are deemed inadequate. The study emphasizes the need for local management policies and solutions such as sea walls and raising properties to address the escalating threat.
