With over 25 years-experience in conflict zones and fragile states, Arthur Snell travels from the heat of the Sahel to the Arctic Circle to show how climate change is coinciding with a breakdown in geopolitical order, increasing conflict, military spending and violence. Within our lifetimes, rising temperatures, sea levels and scarcity will inevitably drive both conflict and mass migration among the world's major powers. Natural disasters and the battle for rare metals that are essential to our technology will shake the established world order to its core within this century. When the rain wrecks India's ability to grow rice, the heat makes building impossible in Saudi Arabia, wildfires rage through America's most populated regions, and in Russia huge areas of highly fertile land are exposed by the melting ice, what will living on a warmer planet actually be like? Here, for the very first time, Oxford-trained historian and former British diplomat Arthur Snell delivers a comprehensive account of the geopolitics of climate change. Through four sections - Earth, Air, Fire and Water - Elemental blends reportage with analysis and interviews from a range of international experts, policymakers and politicians, to reveal the turbulent future we face - and the choices we need to make to avert disaster.
