As Miami's Republican mayor from 2017 to 2025, following his father into the city's public life, he governed a place where rising water and rising heat aren't abstractions, they show up in the streets. He pushed through a stormwater master plan and a formal climate resilience office, arguing that protecting a coastal city is basic infrastructure, not ideology. The record wasn't tidy. Priorities shifted, offices were restructured, and the fight over how far Miami should go never fully settled. He remains one of the clearest examples of a Republican mayor forced to treat the result of long-term environmental changes as a daily governing problem rather than a talking point.
