Former New York City Mayor Bill de Blasio has a unique perspective on the topic of climate resiliency. He was a city official in 2012 for Superstorm Sandy—which many call the worst disaster in New York City’s history—and in 2021 for Hurricane Ida, which caused $24 billion worth of flooding in the Northeastern United States, making it the costliest and most damaging storm since Sandy nine years before. He was also mayor during most of those nine years, when policymakers, planners, and the citizens of New York tried to grapple with the enormous task of making the city more resilient in the face of ever more destructive and dangerous weather events driven by the man-made climate crisis and global warming. With 520 miles of shoreline, 443 miles of underground railroad and subway tracks, and 14 major under-river tunnels, New York City is a nightmare to protect from rising seas and catastrophic rainfall, and de Blasio and city planners proposed billions in dollars of resiliency projects—including extending Manhattan’s shoreline 500 feet at the island’s vulnerable southern tip. But those plans, he says, encountered some surprisingly strong headwinds, including neighborhood opposition, short political and public attention spans, and competing concerns including the COVID-19 pandemic. So how do vulnerable localities like New York City overcome such obstacles and prepare for an increasingly adversarial climate? de Blasio, who is currently a visiting fellow at the Institute of Politics at Harvard Kennedy School, explores the possibilities with host Ralph Ranalli.Bill de Blasio is a Fall 2022 Visiting Fellow at the Institute of Politics at Harvard Kennedy School.
