Warmth is a new kind of book about climate change: not what it is or how we solve it, but how it feels to imagine a future--and a family--under its weight. In a fiercely personal account written from inside the climate movement, Sherrell lays bare how the crisis is transforming our relationships to time, to hope, and to each other. At once a memoir, a love letter, and an electric work of criticism, Warmth goes to the heart of the defining question of our time: how do we go on in a world that may not?
