Waves of climate refugees. Dozens of failed states. All-out war. From one of the world's great geopolitical analysts comes a terrifying glimpse of the near future, when climate change drives the world's powers towards the cutthroat politics of survival. An increase of as little as two degrees Celsius in average global temperature-which is almost inevitable-could heat global politics to boiling point and trigger massive conflicts over scarce food and water. Bringing together extensive interviews and the latest research in this revised and updated edition, Gwynne Dyer reveals the truth about our planet's future. Can our technology save us, or is it too late? Where do our best hopes for damage limitation lie? Prescient and unflinching, Climate Wars will be one of the most important books of the coming years. Read it and find out what we're heading for.
