Impact projections are based on three different climate scenarios-“moderate,” “higher” and “extreme”-associated with future greenhouse gas emissions.

The findings, presented in a 70-page, graphics-rich report, build on work by the Climate Impact Lab, a consortium of scientists, economists and other academics working to measure the real costs of global climate change. Ford School of Public Policy at the University of Michigan. “The sheer numbers of people who will feel direct climate impacts in their lifetimes is very, very significant, and it points to why public policies are necessary right now to start reducing the risks,” said Daniel Raimi, a senior research associate at RFF and lecturer at the Gerald R. Miami will also become “the most vulnerable major coastal city in the world,” RFF said, with hundreds of billions of dollars in assets under assault from winds, storm surges, coastal flooding and sea-level rise. New modeling by Resources for the Future, a nonpartisan economic think tank, reveals that “100-year floods” could occur every few years rather than once a century in many locations, endangering an additional 300,000 homes, 2,500 miles of roadways, 30 schools and four hospitals.

Florida’s next two decades could be more disruptive than any period in its history as climate change threatens the state’s 8,500-mile coastline and chews away at its $1 trillion economy.
