Not long ago, Kenneth Griffin, a hedge-fund billionaire, bought a penthouse in Miami Beach for sixty million dollars, the highest amount ever paid for a single-family residence in Miami-Dade County (and ten million dollars more than the original asking price). The penthouse, in a new building called Faena House, offers eight bedrooms and a seventy-foot rooftop pool. When I read about the sale, I plugged the building’s address into a handy program called the Sea Level Rise Toolbox, created by students and professors at Florida International University. According to the program, with a little more than one foot of rise the roads around the building will frequently flood. With two feet, most of the streets will be underwater, and with three it seems that, if Faena House is still habitable, it will be accessible only by boat.
