Pleasure districts like Miami Beach, built just decades ago, will disappear, as will many of the military installations erected around the world since World War II to defend and secure the wealth that gave rise to them. Much older cities, like Amsterdam, are also under threat from flooding, with extraordinary infrastructure needed already today to keep them above water, infrastructure unavailable to defend the temples and villages of Bangladesh. Farmlands that had produced the same strains of grain or grapes for centuries or more will adapt, if they are lucky, to entirely new crops; in Sicily, the breadbasket of the ancient world, farmers are already turning to tropical fruits. Arctic ice that formed over millions of years will be unleashed as water, literally changing the face of the planet and remodeling shipping routes responsible for the very idea of globalization. And mass migrations will sever communities numbering in the millions — even tens of millions — from their ancestral homelands, which will disappear forever.
