27. Conclusions: A simple organizational structure based on a one-dimensional “horizontal” linkage between climate research and a group of “vertically integrated” research teams in several traditional academic disciplines has proven to be a useful one for the Climate Impacts Group. This research strategy has laid the foundation for future work with increasing horizontal integration between sectors. Research on the capacity of existing institutions identified important research needs and fundamentally altered the CIG’s strategy for education and outreach. CIG Partnerships with regional stakeholders has been a very productive avenue in the context of creating linkages between academia and management agencies, and in the process of developing and refining pilot climate forecast applications.
