I am an academic and writer focusing on environmental issues, especially climate change. I live in Tucson, Arizona and work at the University of Arizona in the School of Geography, Development, and Environment as a Regents professor. I study the human dimensions of global environmental change and climate justice, especially the social causes and consequences of climate change.
Over my career I have taught geography and environmental studies. I helped to build interdisciplinary environmental programs at the University of Arizona, Oxford University in the UK, Penn State University, and the University of Wisconsin-Madison including directing the Institute of the Environment at the University of Arizona and the Environmental Change Institute at Oxford University. I was a PhD student and postdoc at the National Center for Atmospheric Research (NCAR) in Colorado (working with Steve Schneider) and received my degrees from UCLA (PhD Geography), University of Toronto (MA Geography) and University College London (BA Geography).
I have been honored to lead and serve with a number of national and international projects and committees including the Earth Commission of Future Earth, the US-NRC Committee on the Human Dimensions of Global Environmental Change, the US-NRC panel on Informing America’s Climate Choices, the scientific advisory committee for the InterAmerican Institute (IAI) and the ICSU Global Environmental Change and Food Systems (GECAFS) project. I have been an IPCC lead author for several assessments including the recent Special Report on 1.5C.
In 2020 I was honored to be elected to the US National Academy of Sciences and the American Academy of Arts and Sciences.
This web site provides links to my writings – books, articles, media – as well as information on my research interests and projects, my teaching and student advising, and the organizations I advise or support. I have supervised more than 70 graduate students. I am not accepting new students to supervise in Fall 21 or later as I will be on research leave and then moving on to retirement (from teaching and admin, more time for research!)
