Climate Science and Decision Making

This article reviews progress in understanding climate variability and change and how such understanding might better contribute to decision processes and the design of decision support tools. We emphasize the value of collaborative engagement between climate information users and scientists to continue innovation in this area. Our assessment presents opportunities for geographic perspectives and insights that can increase understanding of the physical processes causing interannual variability and improve climate model output for climate impact assessment. As decision-makers’ interests expand to address adaptation, nature-society research can also contribute significantly to understanding the diversity of climate information users, their evolving needs, and to the development of strategies for communicating risk and uncertainty.
