McKenzie Funk has spent six years reporting around the world on how we are preparing for a warmer planet, and he shows us that the best way to understand the catastrophe of global warming is to see it through the eyes of those who see it most clearly - as a market opportunity. Global warming's physical impacts can be separated into three broad categories: melt, drought, and deluge. Funk travels to two dozen countries to profile entrepreneurial people who see in each of these forces a potential windfall. By letting climate change continue unchecked, we are choosing to adapt to a warming world. Containing the resulting surge will be big business; some will benefit, but much of the planet will suffer. McKenzie Funk has investigated both sides, and what he has found will shock us all. To understand how the world is preparing to warm, Windfall follows the money.
