There is rapidly growing interest and compelling need to model and understand the complex interactions, interdependencies, and co-evolutionary pathways of human and natural systems, including the effects of changing weather patterns and extremes, natural resources (e.g., land, water, and energy), economic development, and infrastructure expansion.   Addressing this grand challenge requires convergence among the natural, socioeconomic, and decision sciences. In this Town Hall, DOE will describe its research portfolio, one supporting rapid innovations in integrated human-Earth system modeling centered on open source data and modeling frameworks, HPC, functional communities-of-practice, and collaborative mechanisms. Topics and geographies of interest will be discussed, from integrated hydro-terrestrial modeling to coastal and Arctic regions. Finally, DOE will outline its methods for strengthening stakeholder input (including development of quantitative metrics). Both federal program managers and leading scientists will be presenting with time for audience discussion and feedback.
