In this book, Frank Ackerman offers a refreshing look at the economics of climate change, explaining how conventional economic theories get in the way of understanding this urgent problem. The benefits of climate protection are vital but priceless, and often devalued in cost-benefit calculations. Modest preparation for the most predictable outcomes of global warming is less important than secure protection against the growing risk of catastrophic change; massive investment in new, low carbon technologies and industries is life insurance for the planet.  Ackerman makes an impassioned plea to construct a better economics, arguing that if we can't afford the future, what are we saving our money for?
