Through my work with veterans and clean energy, I have seen how the military is already leading U.S. efforts on tackling this challenge. Since defining climate change as a "threat multiplier" in the 2014 Quadrennial Defense Review, the Department of Defense has laid out the risks climate change poses directly to mission capability and developed a comprehensive roadmap to building a resilient fighting force. The military is replacing their need for oil and cutting their emissions with new clean energy technologies such as diverse fuel sources, more efficient vehicles, and solar power. The Paris Agreement is an additional tool to further their investment in climate change adaptation and reduce the overall burden on the military.
