When Hurricanes Katrina and Rita swept through Louisiana in 2005, cities like Houston, Dallas, and Baton Rouge took in hundreds of thousands of displaced residents—many of whom eventually stayed in those cities a year later. Where evacuees have moved since hasn’t been closely tracked, but data from those initial relocations are helping researchers predict how sea level rise might drive migration patterns in the future. Climate experts expect some 13 million coastal residents in the U.S. to be displaced by the end of this century. A new PLOS One study gives some indication of where climate migrants might go. “A lot of cities not at risk of sea of level rise will experience the effect of it,” says Bistra Dilkina, a computer scientist at the University of Southern California, who led the study. “This will require an adjustment in terms of the [increased] demand on the cities’ infrastructure.” Dilkina […]
