The term “climate change” was included for the first time in the latest revision of the Department of Defense Dictionary of Military and Associated Terms (Joint Publication 1-02), published last week.
Climate change is officially defined by DoD as “Variations in average weather conditions that persist over multiple decades or longer that encompass increases and decreases in temperature, shifts in precipitation, and changing risk of certain types of severe weather events.”
The new entry in the DoD Dictionary reflects a growing awareness of the actual and potential impacts of climate change on military operations.
The definition was originally proposed in the January 2016 DoD Directive 4715.21 on Climate Change Adaptation and Resilience.
“The DoD must be able to adapt current and future operations to address the impacts of climate change in order to maintain an effective and efficient U.S. military,” the January directive stated.
