Between supplying fuel to military bases, planes, and ships, making and using weapons, and clearing land, militaries around the world account for almost 6% of global greenhouse gas emissions.

A new report calculated how much the militaries of the United States and the United Kingdom would hypothetically “owe” if they paid for the damage caused by their carbon emissions. The total came up to $111 billion. So what can the military do about its emissions? And what does militarism in the context of the climate crisis look like?

Ira talks with two of the report’s authors, Khem Rogaly, a senior researcher at London-based think tank Common Wealth, and Dr. Patrick Bigger, research director at the Climate and Community Project, a progressive climate policy think tank in the US.

Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
