Because global climate change is intimately linked to culture, anthropologists are strategically well-placed to interpret it, communicate information about it, and act in response to it both in the field and at home. Fieldworkers are increasingly encountering reports of the local effects of climate change from their research partners, and it is becoming apparent that indigenous peoples' recognized capacity for adaptation to change may not be sufficient to cope with these effects. Fieldwork among Viliui Sakha of northeastern Siberia suggests an action-oriented approach to anthropological climate change research that begins by developing cultural models of the local effects of global climate change, goes on to fill in the gaps with Western scientific knowledge, and ends with the dissemination of that information and its use for the development of adaptive strategies, policy recommendations, and advocacy.
