“Rain bombs” such as Invest 90L are products of our hotter world; warmer air has more room between its molecules for moisture. That water is coming for greater Miami and the 6 million people who live here. This glittering city was built on a drained swamp and sits atop porous limestone; as the sea keeps rising, the National Oceanic and Atmospheric Administration forecasts that South Florida could see almost 11 extra inches of ocean by 2040. Sunny-day flooding, when high tides gurgle up and soak low-lying ground, has increased 400 percent since 1998, with a significant increase after 2006; a major hurricane strike with a significant storm surge could displace up to 1 million people. And with every passing year, the region’s infrastructure seems more ill-equipped to deal with these dangers, despite billions of dollars spent on adaptation.

Thirty years ago, when the dangers of climate change were beginning to be understood but had not yet arrived in force, the creeping catastrophe facing Miami might have been averted. But as atmospheric concentrations of carbon reach levels not seen in 3 million years, politicians promise resilience while ignoring emissions; developers race to build a bounty of luxury condos, never mind the swiftly rising sea. Florida is entering a subtropical state of unreality in which these decisions don’t add up.

The state government isn’t exactly ignoring the rising water. Governor Ron DeSantis and his administration have attempted to address the havoc caused by the changing climate with his $1.8 billion Resilient Florida Program, an initiative to help communities adapt to sea-level rise and more intense flooding. But the governor has also signed a bill into law that would make the term climate change largely verboten in state statutes. That same bill effectively boosted the use of methane, a powerful greenhouse gas, in Florida by reducing regulations on gas pipelines and increasing protections on gas stoves. In a post on X the day he signed the bill, DeSantis called this “restoring sanity in our approach to energy and rejecting the agenda of the radical green zealots.”

Climate researchers, for their part, refer to this strategy as “agnostic adaptation”—attempting to deal with the negative effects of climate change while advancing policies that silence discussion or ignore climate change’s causes. On Friday, at a press conference in Hollywood, Florida—which received more than 20 inches of rain—DeSantis repeated his message, emphasizing that “we don’t want our climate policy driven by climate ideology.”

The Earth’s carbon cycle—which has not witnessed such a rapid increase in atmospheric carbon dioxide in the past 50,000 years—is without ideology. The carbon goes into the atmosphere, and everything that follows follows. In Miami, as the water levels rise, researchers predict that low-lying neighborhoods across the region will lose population. Eventually, Florida’s policies of agnostic adaptation will have to deal with this looming reality, where adaptation is clearly impossible, and retreat is the only option left
