vegetation distribution. Stephenson received his Ph.D. in plant ecology from Cornell University.
Eric Sundquist is a research geologist at the U.S. Geological Survey where he conducts research on relationships between global carbon cycle and atmospheric carbon dioxide. His current research interests include past natural variations in atmospheric carbon dioxide, relationships between oceanic and terrestrial carbon cycling, effects of human land use on carbon dioxide, effects of erosion and sediment transport on carbon dioxide budgets, and exchange of carbon dioxide between soils and the atmosphere. Sundquist received his Ph.D. and A.M. in geology from Harvard University and his B.A. in geology from Pomona College. He is currently on the Climate System Model Advisory Board at of the National Center for Atmospheric Research, is chair of the Committee on Global Environmental Change at the American Geophysical Union, and is a member of the U.S. Carbon Cycle Scientific Steering Group.
Robert T.Watson is the World Bank’s senior spokesperson on climate change. He joined the bank in 1996 as senior scientific advisor in the environment department and was later appointed director of the same department. He is now the bank’s chief scientist and was formerly chairman of the Intergovernmental Panel on Climate Change. Before joining the World Bank, he was associate director for environment in the Office of Science and Technology Policy, Executive Office of the President. Prior to joining the Clinton White House, he was director of the science division and chief scientist for the Office of Mission to Planet Earth at the National Aeronautics and Space Administration. Mr. Watson has played a key role in the negotiation of global environment conventions and the evolution of the Global Environment Facility.
Tristram West is a research scientist at Oak Ridge National Laboratory and a participant in the Department of Energy’s Consortium for Enhancing Carbon Sequestration in Terrestrial Ecosystems. He received a B.S. in agriculture from the University of Kentucky and an M.S. and a Ph.D. in natural resources and agronomy from Ohio State University. West studies changes in terrestrial carbon dynamics associated with changes in land use and management and also the impact of carbon sequestration policies on net greenhouse gas emissions. His current research includes the global quantification of carbon accumulation and loss rates associated with a number of terrestrial carbon sequestration options. West collaborates with a number of federal, state, and academic organizations, and he has published several papers on terrestrial carbon sequestration and full carbon accounting.
