Daniel R. Cayan is a research meteorologist at the Scripps Institution of Oceanography and is also a researcher in the U.S. Geological Survey. His work is directed at understanding climate variability and changes over the Pacific Ocean and North America and climate impacts on water, wildfire, health, and agriculture in California and western North America. Among his recent publications are projections of sea-level extremes along the California coast. Dr. Cayan heads two climate research programs aimed at improving climate information and forecasts for decision makers in the California region: the California Nevada Applications Program and the California Climate Change Center. He is a fellow of the American Geophysical Union. He received a B.S. in meteorology and oceanography from the University of Michigan and a Ph.D. in oceanography from the University of California, San Diego.

Gary B. Griggs is a distinguished professor of earth and planetary sciences and the director of the Institute of Marine Sciences at the University of California, Santa Cruz. His research is focused on the coastal zone and ranges from coastal evolution and development to shoreline processes—including the evaluation of long-term shoreline changes and geomorphic evolution of coastlines—to coastal hazards and coastal engineering. Dr. Griggs is the author or coauthor of several books, including Living with the Changing California Coast and Introduction to California’s Beaches and Coast. He served as chair of the University of California Marine Council from 1999 to 2009 and is a current member and past chair of the science advisory team to the Governor’s Ocean Protection Council. He is a fellow of the California Academy of Sciences. He received a B.A. in geological sciences from the University of California, Santa Barbara, and a Ph.D. in oceanography from Oregon State University.

Weiqing Han is an associate professor in the Department of Atmospheric and Oceanic Sciences at the University of Colorado. Her research interests are in sea level, ocean circulation and dynamics, air-sea interaction, and climate variability and change. Among her recent work is an analysis of patterns of sea-level change in the Indian Ocean and the influence of North Atlantic circulation on glacial sea-level changes. Dr. Han serves on a panel of the World Climate Research Programme Climate Variability and Predictability project, and she is a recipient of a National Science Foundation Faculty Early CAREER Award. She received a B.S. in meteorology from the Nanjing Institute of Meteorology, an M.S. in meteorology from the Chinese Academy of Meteorological Sciences, and a Ph.D. in physical oceanography from the Nova Southeastern University Oceanographic Center.

Benjamin P. Horton is an associate professor in the Department of Earth and Environmental Science at the University of Pennsylvania. His research focuses on mechanisms of sea-level changes, including climate change, earthquakes, tsunamis, and the coastal sedimentary budget. He also has examined the response of estuaries to sea-level rise. He aims to bridge the gap between instrumental and geological observations of sea-level change. Dr. Horton has worked on sea-level rise in several countries; his U.S. work has focused on the contributions of eustacy and isostacy along the Atlantic coast and earthquakes and ground deformation along the west coast. He is a contributing author to the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report, a member of the steering committee of PALSEA (PALeo-constraints on SEA-level rise), and the project leader of the International Geoscience Programme’s Preparing for Coastal Change. He received a B.A. in geography from the University of Liverpool and a Ph.D. in geography from the University of Durham.

Christina L. Hulbe is a professor and chair of the Department of Geology at Portland State University. Her research focuses on understanding and modeling the dynamics of ice sheets, the interactions between ice shelves and ice sheets, and on the role of ice sheets in climate change. New work now under way involves the uncertainty associated with poorly known boundary conditions in mathematical models of ice sheets. Dr. Hulbe is a representative of the NRC’s Scientific Committee on Antarctic Research (SCAR) and co-chairs the local organizing committee for the 2012 SCAR Open Science Conference. She received a B.S. in geological engineering from Montana College of Mineral Science and Technology, an M.S. in geology from Ohio State University, and a Ph.D. in geophysics from the University of Chicago.
