Opinion | Miami’s submarine future

The Economist published a sobering opinion piece on Miami’s “submarine future,” detailing how a metro area of 3 million faces flooding from both rising seas — up nearly a foot in a century — and groundwater seeping through porous limestone, made worse by thousands of failing septic tanks. The column argues that fragmented government and short-term politics, more than the water itself, are the city’s real obstacle, noting the $4 billion price tag just to fix the septic problem.
