Dr. Rosenberg is a Laboratory Fellow, Emeritus,at Battelle's Pacific Northwest National Laboratory (PNNL) Joint Global Change Research Institute (JGCRI). Prior to his retirement in 2004, Dr. Rosenberg lead research on the impacts of climatic variability and potential change on water resources, agriculture and unmanaged ecosystems. Also, under JGCRI's Global Technology Strategy Program (GTSP), Rosenberg was responsible for efforts to develop an understanding of the potential role of biotechnology and genetic engineering in mitigation of global climatic change. Since joining Battelle in 1992, Dr. Rosenberg has coordinated research that provides information to JGCRI's Global Change Assessment Model (GCAM) and integrated assessment tool for understanding the causes and potential effects of environmental change, means of mitigation and adaptation to change that is unavoidable. As one means of mitigation, Rosenberg has conducted research on sequestration of carbon in agricultural soils. He was principal organizer of a workshop and other efforts that led to creation of the DOE-sponsored multi-laboratory research program Carbon Sequestration in Terrestrial Ecosystems (CSiTE). Prior to joining PNNL, Dr. Rosenberg was director of the Climate Resources Program at Resources for the Future in Washington, DC. Before joining RFF in 1987, he was George Holmes Professor of Agricultural Meteorology at the University of Nebraska-Lincoln, which he joined as Assistant Professor in 1961. Dr. Rosenberg is a Fellow of the American Society of Agronomy, the American Meteorological Society, and the American Association for the Advancement of Science. He is also Associate Editor of the journals Climatic Change and Agricultural and Forest Meteorology. An agricultural meteorologist, Dr. Rosenberg has degrees in soil science and meteorology from Michigan State, Oklahoma State, and Rutgers Universities.
