As the planet heats up, competition for resources rises and populations migrate. Even without the impact of natural disasters it’s enough to raise the tensions between nations. Gwynne Dyer is an historian, independent journalist and the author of 2011’s ‘Climate Wars: The Fight for Survival as the World Overheats’. In this episode, James and Gwynne discuss the ways in which climate change could lead to wars in the future, and whether it is possible to prevent this.
