A number of biophysical and socio-economic drivers will have a significant influence on future vulnerability, risk, resilience, and adaptation planning in the Bering-Chuckchi-Beaufort (BCB) region ( Chapters 4-7). The trajectories of some of those drivers are amenable to modeling, forecasting, or projection. However, the future is inherently uncertain, particularly over long time horizons. Scenarios have been used for over 50 years as a tool for exploring such uncertainty in order to identify key driving forces and critical unknowns, as well as to generate shared understanding among stakeholders regarding the potential for, and implications of, alternative futures (van Notten et al., 2003; Bishop et al., 2007; Avango et al., 2013). This chapter provides a general overview of scenarios and their value for understanding the implications of a changing climate within the broader context of global change. The chapter includes a review of how scenarios have been used previously to understand climate change vulnerability, risk, and resilience, with a particular emphasis on the Arctic. It also introduces a new series of qualitative regional and subregional socioeconomic scenarios for the BCB region, peering into the future to 2050, and discusses their implications for climate change impacts as well as adaptation planning and implementation.
