Climate Change-Driven Floods Trigger Mass Migration in the US

Integrating climate change-induced flood risk into future population projections is crucial for understanding the impact of flood exposure on population growth. Research shows that areas with high flood exposure experience slower or negative population growth compared to areas with lower exposure. The study highlights the need for high-resolution data to capture localized impacts and reveals that while larger areas with high flood exposure may be growing, smaller areas within those regions may be driving the growth. The findings emphasize the importance of considering flood risk in population projections and planning for climate change adaptation.
