As the twenty-first century winds onward, it is becoming increasingly clear that understanding how climate affects human cultural systems is critically important. Indeed, it has been argued by many researchers that how we respond to changing global climate is one of the greatest scientific and political challenges facing our planetary technological civilization, comparable and closely intertwined with concerns about biological or nuclear warfare, famine, disease, overpopulation, or environmental degradation. By any reasonable evaluation of the evidence, this century, and likely the several centuries that follow it, will be characterized by dramatic climate change, perhaps as significant in terms of its impact on our species as any climatic episodes that have occurred in the past. What we don’t know with much certainty is how these environmental changes will play out across the planet, and how individuals as well as nation states will respond to them. Archaeology has a major role to play in helping us move through this period of crisis, however, by showing us how human cultures in the past responded to dramatic changes in climate. As the work of many archaeological scholars has shown, climate change has not invariably proven to be a bad thing: it is how people respond to it that is critical (e.g. Anderson et al. 2007b; Cooper and Sheets 2012; Crumley 2000, 2006, 2007; Hardesty 2007; McAnany and Yoffee 2010; McIntosh et al. 2000; Redman 2004a; Sandweiss and Quilter 2008; Sassaman and Anderson 1996; Tainter 2000). Archaeology working in tandem with a host of palaeoenvironmental and historical disciplines has lessons for our modern world and, as this volume demonstrates, we as a profession are making great strides in getting our message out. Perhaps the most important lesson from the past is that people, through their actions, are the drivers of cultural change, including response to climate change. Societies are not, however, monolithic entities that ‘chose’ to succeed or fail; people as individuals, groups, or factions through their actions generate outcomes, and often some demonstrate remarkable flexibility and resilience (Cooper and Sheets 2012; Diamond 2005; McAnany and Yoffee 2010).
