River Floods Will Threaten Tens of Millions in Next 25 Years

According to the study, published yesterday in Science Advances, more than half the United States alone will need to double existing flood protections—through the building of new dikes, levees and other infrastructure updates—to prevent additional people from being affected in the future. Other regions around the world, including central Europe and parts of Africa, Central and South America, as well as large areas of India, Pakistan, Indonesia and China, will also need to take similar measures to protect their populations.
