Our changing climate is accelerating conflict and migration, with the potential to drive political instability from the Sahel to Saudi Arabia to Siberia. From the water-stressed mountains of the Arabian Peninsula to the wildfires raging through America’s most populated regions, the climate crisis is already affecting the lives of millions. 

In a new book, Elemental, former diplomat Arthur Snell explores how global powers must adapt to new vulnerabilities, the risk of future conflicts over natural resources, and the links between the climate crisis and the rise of populism in Europe and the United States.

In this episode, he speaks to journalist Adam McCauley about our rapidly changing geopolitics, the technologies available to help us adapt to a heating planet, the potential for new forms of political cooperation and the choices we need to make to avert disaster.

Arthur Snell is a former British diplomat who has worked in Afghanistan, Iraq and Yemen. His new book is Elemental: The New Geography of Climate Change and How We Survive It.
