From Introduction: This report represents a significant first-step to synthesize environmental information and to use that information to inform others about future conditions and potential outcomes in the BCB region for people and their communities. As such, many scientific uncertainties were identified and information needs noted as they pertain to climate change adaptation planning. Human needs and considerations tend to be considered holistically throughout. This is somewhat novel, especially given that multiple nations (USA, Canada, and Russia) and governance structures are involved. There is a message throughout that ecosystem-level information is a necessary component for understanding climate effects and their interactions, including changing conditions far-removed from the BCB region. The latter includes environmental effects or changes in the marketplace due to globalization. There is strong agreement throughout the report that continuing subsistence activities will be a critical element of food security despite local participation in the cash economy. Subsistence lifestyles and resources must be protected through effective management across the entire BCB region. Within the planning dimension, scenarios could be more effectively employed to guide these strategies by applying the information assembled in this report.
