How do conflicts like the US-Israel war with Iran impact our planet? In this special bonus episode of The Climate Question podcast, we answer listeners’ questions about the environmental cost of armed conflict, from Gaza to Ukraine. We examine the carbon footprint of battle itself - the jets, the bombs, the supply lines - and the impact of maintaining armies and bases during peacetime. We also ask our experts if there are any ways for the military to reduce their emissions and whether commanders now see climate change as a strategic threat. You can hear more episodes of The Climate Question every week, wherever you get your BBC podcasts. Recently, the team have looked at the climate challenge facing the Winter Olympics and Paralympics, the green energy revolution in China and what whales tells us about the state of our planet.
