These long-form essays show Klein at her most prophetic and philosophical, investigating the climate crisis not only as a profound political challenge but as a spiritual and imaginative one, as well. Delving into topics ranging from the clash between ecological time and our culture of “perpetual now,” to the soaring history of humans changing and evolving rapidly in the face of grave threats, to rising white supremacy and fortressed borders as a form of “climate barbarism,” this is a rousing call to action for a planet on the brink.
