Tennessee Extreme Heat

Tennessee faces an above average overall threat from extreme heat and the state has begun to take steps towards understanding how climate change could affect its future heat risks. However, more needs to be done to prepare for future heat events.



For more information on how prepared Tennessee is for its growing extreme heat threat, read the detailed state summary.


Is Tennessee Taking Action?

  • Tennessee addresses its current heat risks through its Hazard Mitigation Plan and communication materials for residents to help prepare for and deal with extreme heat
  • The Department of Health (DOH) tracks heat-related illness, which can be used to monitor changes over location and time, monitor vulnerable areas and populations, and evaluate the results of local climate adaptation strategies
  • The state has not yet conducted a statewide vulnerability assessment that covers the sectors examined and has yet to developed a climate change adaptation plan
