On this bonus episode of Battle Lines we talk to Peter Schwartzstein, author of the upcoming book The Heat and the Fury. From ISIS training grounds in Iraq to the pirate-ridden waters of Bangladesh Peter discovers the unexpected ways in which climate change is feeding global unrest and conflict. 

Across the world, from Europe to Asia, from the Americas to the Middle East, tensions are rising between nation states as the traditional alliances and alignments evolve in the 21st century. 

This year sees war in Europe and the Middle East, and elections in major economies, from the US and the UK to Taiwan. Insurgencies flare in Yemen and Burma, tensions escalate in East Africa, and all around the world the international security architecture buckles under increasing pressure.

Battle Lines, a new podcast from The Telegraph, combines on-the-ground reporting with analytical expertise to help the listener to better understand the course of world politics, wars and tensions, as fault lines grind and slip in an increasingly dangerous and confusing multipolar world.
