Steven Smith’s research focuses on long-term socioeconomic scenarios and the interface between socioeconomic systems and the climate system. Research areas include aerosols, non-CO2 greenhouse gases, renewable energy, the carbon cycle, biomass energy, energy technologies, and land-use changes. Recent research concerns the role of non-CO2 forcing agents in policy scenarios, including sulfate aerosols, black carbon, and non-CO2 greenhouse gases. Model development efforts include implementing in the GCAM framework emissions of non-CO2 greenhouse gases and aerosols (sulfur-dioxide and carbonaceous aerosols). At the Joint Global Change Research Institute, Smith is part of the team that has developed ObjECTS, our new object-oriented modeling framework. Prior to joining PNNL in 1999, Dr. Smith worked with Dr. T.M.L. Wigley as a project scientist at the National Center for Atmospheric Research. Dr. Smith was a lead author for the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios. He also has served on the Panel on Public Affairs of the American Physical Society as well as on the Executive Committee of the APS Forum on Physics and Society. He received his Ph.D. in physics from the University of California-Los Angeles.
