About the Book: In this groundbreaking work, environmental journalist Peter Schwartzstein delivers the first on-the-ground exploration of climate change’s contribution to global conflict. Drawing on over a decade of reporting from dozens of countries—including the ravaged villages of Iraq, where ISIS weaponized drought, and the pirate-ridden waters of Bangladesh—Schwartzstein illuminates the unexpected ways a warming world is feeding global unrest. Through the stories of affected soldiers, farmers, and spies, he makes sense of a form of conflict that remains poorly understood, even as it devastates millions of lives. Despite facing personal danger, Schwartzstein’s unparalleled reporting shows that climate violence is not inevitable; in fact, the same environmental stresses that drive people apart can also compel them to come back together.
