Illustrative scenario
What if Miami took a scaled approach to “Strong building codes”?
Starting point · documented
Dense coastal development concentrates people and assets in the path of tropical cyclones.
The intervention · documented
Strong building codes
Florida's post-Andrew building code requirements for wind resistance and openings.
Demonstrably reduces structural damage in high-wind events.
Schematic direction of change
Adaptation reduces exposure and harm, but the underlying hazard continues to be shaped by global greenhouse gas emissions.
Causes this could address
- Tropical cyclone climatologySoutheast Florida lies within one of the Atlantic basin's most frequently affected regions.
- Concentrated coastal developmentDecades of building close to the shoreline place very large populations and asset values in the surge zone.
Impacts that could ease
- Loss of life and injuryStorm surge is historically the deadliest hazard associated with landfalling hurricanes.
- Large economic lossesConcentrated coastal assets mean a single severe storm can cause very large insured and uninsured losses.
Wider reach at higher intensity is an assumption of this illustration.
How change might unfold
Near term
Early warning and preparedness measures can reduce harm quickly.
Medium term
Infrastructure and urban design changes reduce exposure as they are built out.
Long term
Protection must keep pace with a hazard that continues to intensify unless global emissions fall.
Faded stages are less likely to be reached at scaled intensity.
What this would not change
Local action cannot stop global warming; without global emission cuts the baseline pressure keeps rising.
What it depends on
- Sustained funding and institutional capacity
- Consistent enforcement and monitoring
- Local stakeholder support
- Participation of affected communities
