The Cultures Endangered by Climate Change

As I write this, the website CO2 Now reports that the average atmospheric CO2 level for July 2013 at the Mauna Loa Observatory was 397.23 parts per million, slightly below the landmark 400+ ppm levels recorded in May. The vast majority of climate scientists now argue, not about whether we will witness anthropogenic atmospheric change, but how much and how quickly the climate will change. Will we cross potential ‘tipping points’, when feedback dynamics accelerate the pace of warming?

While climate science might be controversial with the public in the US (less so here in Australia and among scientists), the effects on human populations are more poorly understood and unpredictable, both by the public and scientists alike. Following on from Wendy Foden and colleagues’ piece in the PLOS special collection proposing a method to identify the species at greatest risk (Foden et al. 2013), I want to consider how we might identify which cultures are at greatest risk from climate change.

Will climate change threaten human cultural diversity, and if so, which groups will be pushed to the brink most quickly? Are groups like the Viliui Sakha at the greatest risk, especially as we know that climate change is already affecting the Arctic and warming may be exaggerated there? And what about island groups, threatened by sea level changes? Who will have to change most and adapt because of a shifting climate? Daniel Lende (2013: 496) has suggested that anthropologists need to put our special expertise to work in public commentary, and in the area of climate change, these human impacts seem to be one place where that expertise might be most useful.
