One of India's greatest writers, Amitav Ghosh, argues that future generations may well think so. How else can we explain our imaginative failure in the face of global warming? In this groundbreaking return to non-fiction, Ghosh examines our inability-at the level of literature, history and politics-to grasp the scale and violence of climate change. The climate crisis asks us to imagine other forms of human existence-a task to which fiction, Ghosh argues, is the best suited of all forms. The Great Derangement serves as a brilliant writer's summons to confront the most urgent task of our time.
