DeBuys says that this book did not start out to be a book on climate change but as a general environmental history of the Southwest. It was already becoming obvious that the growth in the Southwest could not continue, this was especially true of the Phoenix area but applied to the entire region. He could see that the environmental factors that were the subject of the book were being exacerbated by climate change and that end was going to come a lot sooner.
It becomes at once obvious that William deBuys loves the desert Southwest. His prose is almost poetic sometimes making it a wonderful read. It is full of history and science, politics and human stories.
I recommend this book to everyone. There are human stories as well as history and science. While the desert Southwest is on the frontlines climate change is already impacting us all.
