Susan A. Crate is an associate professor of anthropology in the Department of Environmental Science & Policy at George Mason University. An environmental and cognitive anthropologist, she has worked with indigenous communities in Siberia since 1988.

Crate is the author of numerous peer-reviewed articles and one monograph, Cows, Kin and Globalization: An Ethnography of Sustainability (AltaMira Press, 2006), and she is co-editor of the Anthropology and Climate Change: From Encounters to Actions (Left Coast Press, 2009). Crate also served on the American Anthropology Association’s Task Force on Climate Change. Mark Nuttall is Professor and Henry Marshall Tory Chair of Anthropology at the University of Alberta. He also holds a visiting position as Professor of Climate and Society at Ilisimatusarfik/University of Greenland and the Greenland Climate Research Centre at the Greenland Institute of Natural Resources. He has carried out extensive research in Greenland, Alaska, Canada, Finland and Scotland, and is co-PI of the EU-funded project ICE-ARC (Ice, Climate and Economics—the Arctic Region in Change). He is editor of the landmark three-volume Encyclopedia of the Arctic (Routledge, 2005) and author or editor of many other books.
