When the water receded after Hurricane Milo of 2030, there was a foot of sand covering the famous bow-tie floor in the lobby of the Fontainebleau hotel in Miami Beach. A dead manatee floated in the pool where Elvis had once swum. Most of the damage occurred not from the hurricane’s 175-mph winds, but from the 24-foot storm surge that overwhelmed the low-lying city. In South Beach, the old art-deco buildings were swept off their foundations. Mansions on Star Island were flooded up to their cut-glass doorknobs. A 17-mile stretch of Highway A1A that ran along the famous beaches up to Fort Lauderdale disappeared into the Atlantic. The storm knocked out the wastewater-treatment plant on Virginia Key, forcing the city to dump hundreds of millions of gallons of raw sewage into Biscayne Bay. Tampons and condoms littered the beaches, and the stench of human excrement stoked fears of cholera. More than 800 people died, many of them swept away by the surging waters that submerged much of Miami Beach and Fort Lauderdale; 13 people were killed in traffic accidents as they scrambled to escape the city after the news spread – falsely, it turned out – that one of the nuclear reactors at Turkey Point, an aging power plant 24 miles south of Miami, had been destroyed by the surge and sent a radioactive cloud over the city.
The president, of course, said Miami would be back, that the hurricane did not kill the city, and that Americans did not give up. But it was clear to those not fooling themselves that this storm was the beginning of the end. With sea levels more than a foot higher than they’d been at the dawn of the century, South Florida was wet, vulnerable and bankrupt. Attempts had been made to armor the coastline, to build sea walls and elevate buildings, but it was a futile undertaking. The coastline from Miami Beach up to Jupiter had been a little more than a series of rugged limestone crags since the mid-2020s, when the state, unable to lay out $100 million every few years to pump in fresh sand, had given up trying to save South Florida’s world-famous beaches. In that past decade, tourist visits had plummeted by 40 percent, even after the Florida legislature agreed to allow casino gambling in a desperate attempt to raise revenue for storm protection. The city of Homestead, in southern Miami-Dade County, which had been flattened by Hurricane Andrew in 1992, had to be completely abandoned. Thousands of tract homes were bulldozed because they were a public health hazard. In the parts of the county that were still inhabitable, only the wealthiest could afford to insure their homes. Mortgages were nearly impossible to get, mostly because banks didn’t believe the homes would be there in 30 years. At high tide, many roads were impassable, even for the most modern semiaquatic vehicles.
But Hurricane Milo was unexpectedly devastating. Because sea-level rise had already pushed the water table so high, it took weeks for the storm waters to recede. Salt water corroded underground wiring, leaving parts of the city dark for months. Drinking-water wells were ruined. Interstate 95 was clogged with cars and trucks stuffed with animals and personal belongings, as hundreds of thousands of people fled north to Orlando, the highest ground in central Florida. Developers drew up plans for new buildings on stilts, but few were built. A new flexible carbon-fiber bridge was proposed to link Miami Beach with the mainland, but the bankrupt city couldn’t secure financing and the project fell apart. The skyscrapers that had gone up during the Obama years were gradually abandoned and used as staging grounds for drug runners and exotic-animal traffickers. A crocodile nested in the ruins of the Pérez Art Museum.
And still, the waters kept rising, nearly a foot each decade. By the latter end of the 21st century, Miami became something else entirely: a popular snorkeling spot where people could swim with sharks and sea turtles and explore the wreckage of a great American city.
Even more than Silicon Valley, Miami embodies the central technological myth of our time – that nature can not only be tamed but made irrelevant. Miami was a mosquito-and-crocodile-filled swampland for thousands of years, virtually uninhabited until the late 1800s. Then developers arrived, canals were dug, swamps were drained, and a city emerged that was unlike any other place on the planet, an edge-of-the-world, air-conditioned dreamland of sunshine and beaches and drugs and money; Jan Nijman, the former director of the Urban Studies Program at the University of Miami, called 20th-century Miami “a citadel of fantastical consumption.” Floods would come and go and hurricanes might blow through, but the city would survive, if only because no one could imagine a force more powerful than human ingenuity. That defiance of nature – the sense that the rules don’t apply here – gave the city its great energy. But it is also what will cause its demise.
You would never know it from looking at Miami today. Rivers of money are flowing in from Latin America, Europe and beyond, new upscale shopping malls are opening, and the skyline is crowded with construction cranes. But the unavoidable truth is that sea levels are rising and Miami is on its way to becoming an American Atlantis. It may be another century before the city is completely underwater (though some more-pessimistic scientists predict it could be much sooner), but life in the vibrant metropolis of 5.5 million people will begin to dissolve much quicker, most likely within a few decades. The rising waters will destroy Miami slowly, by seeping into wiring, roads, building foundations and drinking-water supplies – and quickly, by increasing the destructive power of hurricanes. “Miami, as we know it today, is doomed,” says Harold Wanless, the chairman of the department of geological sciences at the University of Miami. “It’s not a question of if. It’s a question of when.”
