A forceful call to climate change action and a pragmatic roadmap toward sustainability from the internationally acclaimed author of The Weather Makers. Utilizing the most up-to-the-minute data available, Tim Flannery offers a guided tour of the environmental challenges we face and their potential solutions in both the big picture and in specific detail. He explores everything from techniques for storing the carbon that dead plants release into the earth to the fragile balancing act between energy demands and food supply in India and China, from carbon-trading schemes in South America to a collaboration between a Danish wind-energy company and an automobile manufacturer that may produce a viable electric car and end the reign of big oil. Now or Never is a powerful, thought-provoking, and essential book about the most urgent issue of our time. It burns with Flannery’s characteristic mix of passion, scientific precision, and “offhand interdisciplinary brilliance” (Entertainment Weekly). “Shocking . . . [Flannery] writes for a general audience with passion and clarity.” —Jim Hansen
