The impact of war on the climate is much more than just the emissions from tanks, ships and warplanes. Modern warfare has a devastating effect on both people and the planet.

So what is the scale of planetary destruction wrought by militaries? And in a world where nations justify war on the basis of supposed “security” benefits, isn’t the harm to the Earth not also a huge threat to our collective security?

In this episode of All Hail the Planet – a series delving into the social, economic and political forces undermining meaningful global action on climate change – Ali Rae speaks with Nick Buxton, an author and researcher at the Transnational Institute (TNI); Marwa Daoudy, an author and associate professor of international relations at Georgetown University; and Neta Crawford, a political scientist and the co-director of Brown University’s Costs of War project.
