I write regularly for OnEarth and OnEarth.org, the publications of the Natural Resources Defense Council, and for my updating of the big-picture ideas about the aridity of the West I relied on the up-to-the-minute reporting of my colleagues at that magazine, particularly that of Michael Kodas on the western fires. For a larger synthesis of current and coming climate changes I looked toward Fred Pearce's When the Rivers Run Dry: Water--the Defining Crisis of the Twenty-First Century and, especially, A Great Aridness: Climate Change and the Future of the American Southwest by William deBuys, a writer who calmly but convincingly presents a terrifying picture of the current and future West.
