Climate change in Tennessee
Climate change in Tennessee encompasses the effects of climate change, observed and projected changes in temperature, precipitation, extreme weather, and ecological impacts in the U.S. state of Tennessee, as documented by federal and state scientific agencies.
It has been observed that Tennessee's climate has warmed slightly in recent decades, and precipitation patterns have shifted, with an increase in heavy rainfall events.
Global warming in the United States has been a salient topic since the Kyoto Protocol, as part of the United Nations Framework Convention on Climate Change, that was established in 1992. The effects of global warming have been widely debated; however, there is evidence that suggests a slight increase in the core temperature of most states. In addition, there seems to be a number of effects on ecological systems throughout the United States. In Tennessee, one key effect is the radical changes to the geological composition and wildlife health of the Ohio-Tennessee Basin.
Records analyzed by the National Oceanic and Atmospheric Administration (NOAA) indicate that average annual temperatures in Tennessee have varied over time, with a general warming trend observed in recent decades.
Precipitation has also increased compared to early 20th-century averages, with a greater share of rainfall occurring during heavy precipitation events.
The southeastern United States has experienced an increase in heavy rainfall events since the mid-20th century. In Tennessee, major flood events have included the 2010 Tennessee floods and the 2021 Tennessee floods, both of which caused fatalities and extensive property damage.
Flood management relies heavily on reservoir systems operated by the Tennessee Valley Authority (TVA) and the United States Army Corps of Engineers. These systems reduce, but cannot eliminate, flood risk during extreme rainfall.
Some historical and ecological studies note that the Ohio-Tennessee Basin has experienced changes including nutrient enrichment, altered watershed characteristics, and increased pollutant concentrations.
