The risk of flooding for US coastal cities has risen significantly over the past century
Posted On July 27, 2015
Changing storm dynamics have made flooding a much bigger problem in the US, according to a nationwide study published in Nature Climate Change today. By analyzing historical storm data, researchers have found that the likelihood of a coastal city experiencing severe rainfall and storm surge at the same time is far greater nowadays than it was in the middle of the 20th century. And that combination has substantially amplified the risk of flooding in coastal counties over the course of the past century — counties that house about 40 percent of the US population.
