The inspiration for this book arose from a highly regarded class I teach at the University of Arizona, in which 30-40 undergraduate and graduate students from many disciplines and programs learn about the basic science of global environmental change. The students are diverse in their interests (they come not just from natural science programs, but also from social science, engineering, and education programs), and in their preparation (from undergraduate juniors to Ph.D. candidates). I try to teach this material in a way that allows everyone to grasp the important points even if the subject is new to them, while including the very latest science from research journals to keep the more advanced students engaged. My goals, beyond helping students to learn the basic material, include highlighting the interconnectedness of global change science and inspiring students to pursue, create and disseminate further knowledge in this field. Why write a textbook in such a rapidly expanding field? No semester-long class can convey the full breadth and depth of knowledge in global change science; no textbook can accomplish this either. With this book, I aim to provide a resource for the teaching of global change that offers a foundation in the appropriate subjects and a springboard for curiosity about further reading and research. This book will serve as an introduction to the science of global environmental change and an inspiration for students to pursue further coursework and research that is grounded in a global change context. I also hope it will help instructors to design interdisciplinary global change courses that reach beyond their immediate areas of expertise. The topics range across physical climate science, biogeochemistry, ecosystems, and global change impacts; I have also included sections on societal responses to and drivers of environmental change. I expect the science chapters (sections 1-3 in attached outline) to make up roughly 65 of the book. Each chapter will include references for further reading, and a website (regularly maintained) will update these listings with recent journal and policy publications. I expect this book will be a starting point for students who want to go further in environmental change research, or a strong, state-of-the-art summary for those whose careers lie in other directions.
