Todd Sanders and Elizabeth Hall bring our debates about interdisciplinarity to climate change, a major global issue for which the need for interdisciplinary perspectives is taken for granted. How, they ask, “do we imagine and practice 'interdisciplinarity’ to save the planet?” The authors describe and critique a range of contrasting modalities for doing interdisciplinary work on climate change and the assumptions under which they operate. Sanders and Hall also reflect on the complexities of studying interdisciplinarity when its practitioners and observers are part of the same milieu—both being “natives” in the world of research.
