Study: Rising sea levels could push some US migration to inland cities from coast
Rising sea levels caused by climate change may drive US coastal residents to areas far from the seaboard, not just to adjacent inland regions, according to a study published online in the journal Nature Climate Change.
Even landlocked states such as Arizona and Wyoming could see significant increases in population because of coastal migration by 2100, and may be unprepared to handle the surge, said the analysis from a University of Georgia researcher. "We typically think about sea-level rise as being a coastal challenge or a coastal issue," Mathew Hauer, author of the study and head of the Applied Demography program at the University of Georgia, said in an interview on Tuesday. "But if people have to move, they go somewhere."
The U.S. National Oceanic and Atmospheric Administration predicted in January a 1-to-8-foot (0.3-2.5 metre) increase in sea levels by the year 2100. Previous research by Hauer and others has put the number of Americans displaced as high as 13.1 million.
