DeBuys’ book, A great aridness: climate change and the future of the American southwest, examines how the West will adapt to drying and warming in an era of climate change. Despite the complexity of the issues involved, deBuys is able to convey his key ideas in poetic language, while never oversimplifying his topic. This is a book written by someone with a deep knowledge and love of the southwest. He begins his work by discussing the earlier peoples of the Southwest -such as the Ancestral Puebloans/Anasazi and Hohokam- and their own experience of drought and water management. He then moves on to discuss the central issues of water distribution in the modern era. Why are Arizona’s water rights junior to those of California, so that that in a crisis California will receive its allocation of water, while Arizona’s will be cut? The answers are as fascinating as they are strange.

The central theme of denial runs throughout this work. People don’t want to know the details of how they receive water, or how vulnerable Lake Meade may be. Real estate developers in particular do not want an informed community discussion of this topic. Meanwhile, pragmatic water managers are working to build a water intake drain at the very bottom of Lake Meade. While the book focuses on the American southwest, its central issue is that of climate change, which is why I am reviewing it in a course on global studies. The American southwest is a case study for the future, with applicability from Portugal to Iraq.

The U.S. southwest faces sustained warming and drying, even as more people move into the sunbelt in coming decades. The environment that these people enter will change drastically within their lifetimes. In Chapter 2 “Oracle: Global Change Type Drought,” deBuys examines the impact that climate change will have upon entire ecosystems. On page 46, deBuys has a map of Western forests that are being decimated by the spruce beetle, the mountain pine beetle, and the Piñon Ips beetle. The damage extends as far north as the Yukon. My own family lives in British Columbia, where entire swathes of the north have turned red with the needles of dying trees. De Buys describes what may lay in store for the north: …
