Dr. John R. Christy is 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 November 2000 Gov. Don Siegelman appointed him to be AlabamaĆ¢s State Climatologist. In 1989 Dr. Roy W. Spencer, a NASA/Marshall scientist, and Christy developed a global temperature data set from microwave data observed from satellites beginning in 1979. For this achievement, the Spencer-Christy team was awarded NASA's Medal for Exceptional Scientific Achievement in 1991. In 1996, they were selected to receive a Special Award by the American Meteorological Society "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 (1992, 1994 and 1996) and Lead Author (2001) for the U.N. reports by the Intergovernmental Panel on Climate Change in which the satellite temperatures were included as a high-quality data set for studying global climate change. He has or is serving on five National Research Council panels or committees and has performed research funded by NASA, NOAA, DOE, DOT and the State of Alabama and has published many articles including studies appearing in Science, Nature, Journal of Climate and The Journal of Geophysical Research. Dr. Christy has provided testimony to several congressional committees.
