With its fast food restaurants, churches and strip malls, this city in southeast Florida looks like much of America. But on a sunny day last month, city official Hector Castro talked about its resemblance to Italy’s slowly sinking Venice. “At some point in the future, some places may be uninhabitable,” said Castro. “Maybe people could live in the top part of buildings. But what do you do about the roads?” These predictions about an underwater city may sound horrible, but officials here say they are already changing infrastructure with climate change in mind. Recent storms hit the 4. 4-square-mile city to such a degree that some homes were abandoned for the first time. It was the kind of heavy rainfall that could become more frequent with climate change, even though scientists say no weather event can be tied to warming temperatures. Simultaneously, the city’s freshwater supply is being contaminated by saltwater intrusion— a problem that was not created by climate change, but that is likely being accelerated by it. So city officials are spending some $16 million to move the city’s entire drinking supply to the west to get out of the way of the ocean. It is a temporary fix for a problem that is projected to get worse as time goes on. There may be limits on how much to protect the city from flooding and saltwater intrusion with existing technologies. No one knows how long serious trouble will come— it could be 30 years or so, or it could be later.
