Development and population growth intensify flood risks, analysis shows

In an academic paper and an article more accessible for non-scientists, researchers report that over the next 30 years, the cost of flood damage in the U.S. is on pace to rise 26% due to climate change alone. Factoring in population growth, however, makes the increase in flood losses four times higher than the climate-only effect. The study also found that the current flood risk is predominantly concentrated in white, impoverished communities, many of them on the coasts or in Appalachian valleys, whereas the 30-year increase in risk falls disproportionately on urban and rural communities with large Black populations on the Atlantic and Gulf coasts. New Flood Maps Show US Damage Rising 26% in Next 30 Years Due to Climate Change Alone, and the Inequity is Stark includes an interactive map providing risk estimates by county.
