The U.S. military is one of the world’s largest consumers of fossil fuels. And its carbon pollution is equally huge. At the same time, climate disruption is already amplifying crises and conflicts around the world — making climate change, in the words of one military expert, “a threat multiplier.”

The Department of Defense has been making moves to reduce its dependence on fossil fuels. The Air Force has recently invested in electric aircraft, and several bases are tapping into geothermal energy — capturing heat from deep underground. Others are building their own microgrids — islands of electricity that can run on clean sources. This week we explore how the U.S. military is trying to balance global security with climate threats.

This episode also features a reported story by NPR’s Quil Lawrence, originally broadcast on NPR’s All Things Considered on October 2, 2023.

Guests:

Sherri Goodman, Secretary General, International Military Council on Climate & Security 

Neta C. Crawford, Montague Burton Professor of International Relations, University of Oxford
