In this bracing response to climate change, Roy Scranton combines memoir, reportage, philosophy, and Zen wisdom to explore what it means to be human in a rapidly evolving world, taking readers on a journey through street protests, the latest findings of earth scientists, a historic UN summit, millennia of geological history, and the persistent vitality of ancient literature. Expanding on his influential New York Times essay (the #1 most-emailed article the day it appeared, and selected for Best American Science and Nature Writing 2014), Scranton responds to the existential problem of global warming by arguing that in order to survive, we must come to terms with death.
