The book responds to proceedings of the past couple of decades, especially the efficacy of collective action in light of reports of the Intergovernmental Panel on Climate Change (IPCC). The types of adaptation to climate that are described in this volume have received less attention in the economics literature than have policies for mitigation of emissions. The chapters in this volume provide important new empirical information on and analyses of the economics of climate change. They examine responses to past climatic events and in so doing indicate the range of possible future adaptations. This knowledge is critical for understanding how society has reacted to similar occurrences in the past and for developing effective, new private and governmental policies to address them. The chapters describe research findings regarding historical climate-related events as they have been faced in the American economy; the responses of individuals, organizations, and government institutions to those climate challenges; and assessments of their successes in addressing potential disruptions and in promoting the continued economic growth and welfare. The chapters also provide new data sources for measuring and evaluating how economic agents have adjusted to and progressed even in light of formidable environmental concerns.
