Research indicatesHauer, M. E. (2017). Migration induced by sea-level rise could reshape the US population landscape. Nature Climate Change, 7(5), 321-325. doi:10.1038/nclimate3271 that an increasing number of people in the United States may be considering moving away from areas particularly vulnerable to climate change impacts.
