Surface Temperature Reconstructions for the last 2,000 Years
Aeronautics and Space Administration/World Meteorological Organization (NASA/WMO) ozone trends panel and was lead author of an appendix on statistics for the panel’s report. He has also served on panels of the NRC, Environmental Protection Agency (EPA), NASA, and the Intergovernmental Panel on Climate Change (IPCC). He has studied methods for detecting trends in geophysical time series such as stratospheric ozone, surface temperatures, and atmospheric concentration of chlorofluorocarbons (CFCs). Dr. Bloomfield also spent several years working in a financial institution, building a statistical model of the risks in special-purpose financial companies, and continues to consult on financial problems. He received his Ph.D. in statistics from the University of London.
John R. Christy is a professor of atmospheric science and director of the Earth System Science Center at the University of Alabama in Huntsville, where he began studying global climate issues in 1987. In 2000 he was appointed state climatologist of Alabama. In 1989, Dr. Roy Spencer (then a NASA/Marshall scientist) and Dr. Christy developed a global temperature dataset from microwave data observed from satellites beginning in 1979, for which they were awarded NASA’s Medal for Exceptional Scientific Achievement. They also received a special award from AMS “for developing a global, precise record of earth’s temperature from operational polar-orbiting satellites, fundamentally advancing our ability to monitor climate.” Dr. Christy has served as a contributor and lead author for the IPCC reports in which the satellite temperatures were included as a high-quality dataset for studying global climate change. He is a former member of several NRC committees, including the Panel on Reconciling Temperature Observations and the Committee on Utilization of Environmental Satellite Data. Dr. Christy received his Ph.D. in atmospheric sciences from the University of Illinois.
Kurt M. Cuffey is a professor of geography at the University of California, Berkeley. Dr. Cuffey explores the interface between climatology and geomorphology and has a particular interest in the earth’s great ice sheets. His research efforts emphasize environmental change of polar regions, with a focus on glaciological problems. He uses geophysical techniques to reconstruct histories of temperature and snowfall rate over the ice sheets. He is also working on a better understanding of the physical and chemical processes that determine ice composition as a function of climate. Dr. Cuffey pioneered the use of borehole thermometry to obtain a temperature calibration of the oxygen isotope record in ice cores from Summit Greenland. He is a fellow of the AGU, and in 2003 he was awarded AGU’s Macelwane Medal. Dr. Cuffey received his Ph.D. from the University of Washington.
Robert E. Dickinson is a professor in the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. His areas of interest include the dynamics of atmospheric planetary waves, stratospheric dynamics, models of global structure and dynamics of terrestrial and planetary thermosphere, non-local thermodynamic equilibrium infrared radiative transfer in planetary mesopheres, global climate modeling and processes, the role of land processes in climate systems, the modeling role of vegetation in regional evapotranspiration, and the role of tropical forests in climate systems. Dr. Dickinson is a member of the National Academy of Sciences (NAS) and the National Academy of Engineering (NAE) and a fellow of AAAS and AGU. He has served on
