“New Perspectives on Biogeochemical Cycles and Human Impacts On Our Planet,” William H. Schlesinger, President of the Cary Institute of Ecosystem Studies, introduced by Ross Virginia, Myers Family Professor of Environmental Science, Director of the Institute of Arctic Studies, and PI of the NSF IGERT Program in Polar Environmental Change. Dr. Schlesinger was among the first to quantify the amount of carbon held in soil organic matter globally, providing subsequent estimates of the role of soils and human impacts on forest and soils in global climate change.
Dr. Schlesinger talked about new ways of examining global biogeochemical cycles and assessing human impact on the cycles of important biogeochemical elements. He focused on the ongoing, major impact to the cycles of carbon and nitrogen, and what we have learned by large-scale long-term field experiments. His talk was sponsored by IGERT Dialogues in Polar Science, Engineering, and Society and the Institute of Arctic Studies at the Dickey Center.
