South Florida - A disaster of our making. Bye, Bye South Florida

“This is just from rain,” says Lee Gottlieb, an environmental activist and 40-year resident of South Florida. “I don’t think it’s rained here in five, six days.”

But the rainwater pools anyway. Virtually all of South Florida is only a few feet above sea level. “They elevated the runway,” Mr. Gottlieb says, “but all the terminals …” he pauses, exasperated. “Obviously, if we had a major deluge – this is a flood area.”

It has become increasingly commonplace for politicians at every level of U.S. government – from small-town mayors to the President himself – to describe climate change as the single most important challenge of the coming century. Such rhetoric is buoyed by myriad crises, from sinking land mass in southern Louisiana to historic droughts in California. In low-lying Florida, the culprit is the rising sea level. Should the ocean crawl just one more foot up the edges of this peninsula – something that’s projected to happen in the next two decades, by some estimates – most of the canal systems that keep the saltwater out of the area’s drinking wells would cease to function. A few more feet, and entire towns suddenly turn neo-Venetian, the roads flooded, the infrastructure almost impossible to salvage.

But beyond the dire warnings, something else is happening in South Florida. Here, for the first time in North America, the conversation is no longer just about what climate-change countermeasures or conservation initiatives to pursue – taking shorter showers or subsidizing electric cars. It’s about a much more existential question: What if it’s too late?

…

Scientists are starting to suggest that, in the long run, much of South Florida cannot be saved and that policymakers should begin planning for how to best deal with a massive northward exodus in the coming decades, as some of the most iconic real estate on the continent begins to succumb to the sea.

“Sooner or later, this city, as you see it right now, won’t be like this,” says Henry Briceño, a water-quality researcher at Florida International University. “Miami and the whole of South Florida is not going to be like this any more. So we have to develop a way to plan and supply services in a changing scenario, and that’s not easy. And then, sooner or later, we’ll have to move. Most of the population will have to move.”
