Florida faces significant challenges due to climate change. Rising temperatures, sea-level rise, and extreme weather events threaten coastal areas, ecosystems, and daily life across the state.
Scientists have observed clear evidence of climate change globally. In Florida, these impacts are particularly acute, affecting everything from coral reefs to urban infrastructure. State and local governments are implementing various policies to address these challenges.

Scientific evidence for climate change
- Global temperatures rising 1.1°C since pre-industrial era
- Atmospheric CO2 levels increased from 280 ppm to over 410 ppm since 1750
- Arctic sea ice extent decreased by 13% per decade since 1979
- Ocean pH dropped by 0.1 units becoming 30% more acidic since industrial revolution
Vulnerability of Florida's coastal areas
- Sea-level rise causes:
- Oceans expand as they warm
- Melting ice sheets and glaciers add water volume
- Projected rise 1-4 feet (30-120 cm) by 2100 threatens low-lying areas (Miami Beach)
- Coastal erosion accelerates damaging beachfront properties (Satellite Beach)
- Nuisance flooding increases in frequency disrupting daily life (St. Augustine)
- Storm surge amplification worsens hurricane impacts (Hurricane Michael, 2018)
- Saltwater intrusion contaminates freshwater aquifers (Biscayne Aquifer)
Consequences for Florida's ecosystems
- Coral reefs degrade from bleaching and acidification (Florida Keys)
- Everglades face altered water patterns impacting wading birds (Wood Stork)
- Mangroves migrate northward replacing salt marshes (Tampa Bay)
- Species distribution shifts:
- Migratory birds alter patterns (Swallow-tailed Kite)
- Tropical species move north (Snook)
- Invasive species proliferate (Burmese Python)
- Sea turtle nesting affected by eroding beaches and temperature changes (Loggerhead)
Climate change policies in Florida
- State initiatives:
- Florida Climate Change Action Plan sets emission reduction goals
- Resilient Florida Grant Program funds adaptation projects
- Local actions:
- Miami-Dade County implements Sea Level Rise Strategy
- Southeast Florida Regional Climate Change Compact coordinates regional efforts
- Infrastructure adaptations:
- Raising road elevations (Miami Beach)
- Installing pumping stations and seawalls (Fort Lauderdale)
- Ecosystem protection:
- Coral reef restoration (Dry Tortugas)
- Everglades restoration improves water flow
- Renewable energy:
- Solar energy incentives boost adoption
- Electric vehicle charging infrastructure expands
