  • Arizona’s State Hazard Mitigation Plan is helping it prepare for current climate risks, as are programs to help mitigate hazards, emergency preparedness and communication materials
  • Arizona's Department of Health Services Extreme Heat Preparedness Plan specifically addresses extreme heat, as does a Department of Transportation climate change vulnerability assessment
