Peter W Swarzenski Patrick L. Barnard 2025 A rigorous analysis of 21st Century multi-hazard exposure for U.S. Southeast Atlantic coastal communities indicates that up to 70% of residents will be exposed daily to shallow and emerging groundwater by ~2100, 15 times higher than from surficial flooding alone. This threat further exacerbates other coastal stressors, such as flooding, subsidence, and beach erosion, that impact these vulnerable coastal communities and ecosystems under expected future climate change scenarios. application/pdf 10.1038/s41558-024-02181-1 en Nature Predicted exposure of communities in southeastern United States to climate-related coastal hazards article
