On Fire gathers for the first time more than a decade of her impassioned writing from the frontline of climate breakdown, and pairs it with new material on the staggeringly high stakes of what we choose to do next.Here is Klein at her most propheticand philosophical, investigating the climate crisis not only as a profound political challenge but also as a spiritual and imaginative one. Delving into topics ranging from the clash between ecological time and our culture of 'perpetual now,' 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.
