Speakers' Bios

Dr. E. Calvin Beisner, who earned the Ph.D. at St. Andrews, Scotland, is the founder and the national spokesman for the Cornwall Alliance for the Stewardship of Creation. A co-author of the Cornwall Declaration on Environmental Stewardship and A Call to Truth, Prudence, and the Protection of the Poor: An Evangelical Response to Global Warming, he is also author of three books on the relationship of population, economic development, resources, and the environment, including Where Garden meets Wilderness: Evangelical Entry into Environmental Debate, and was managing editor of the late Julian Simon's last major edited work, The State of Humanity. He has testified before the Senate Environmental and Public Works Committee, briefed the White House Council on Environmental Quality, spoken to the Minnesota State Legislature, and presented a paper at the Vatican's Conference on Climate Change. He is leading a newly planted congregation of the Orthodox Presbyterian Church in south Florida. He and his wife have seven children, one of whom, David Beisner, is a student at Bryan College.


Dr. Christopher Essex, Ph. D., York University in Toronto, is a full professor in the Department of Applied Mathematics at the University of Western Ontario. He recently stepped down as Director of UWO's Program in Theoretical Physics to become Associate Chair of the Department of Applied Mathematics. When completing his Masters at Rice University in Texas in 1978 he built his first climate model which (given the technology of the time) put him on intimate terms with the individual rotation lines of the C02 15 micron band. After completing his Ph.D. based on work concerning the thermodynamics of radiation, he joined the Canadian Climate Centre’s General Circulation Modeling group as a National Sciences and Engineering Research council postdoctoral fellow. In 1986 he held the post as an Alexander von Humboldt Research Follow and was received at the mansion of the President of Germany. From 2002 to 2003 he was a sabbaticant at the Niels Bohr Institute in Copenhagen and his numerous publications on radiation thermodynamics continue to be cited in prominent academic journals. He is in steady demand as a speaker at international scientific conferences. He is an award-winning teacher and is the recipient, with Ross McKitrick, of the 2002, $10,000 Donner Prize for the book, Taken by Storm: The Troubled Science Policy, and Politics of Global Warming. In October 2006 he was appointed (by the Queen) to the National Sciences and Engineering Council.


Dr. Lowell (Rusty) Pritchard Jr. received the Ph.D. in Food and Resource Economics from the University of Florida. His M.S., also from the University of Florida, was in Environmental Engineering Sciences (Systems Ecology). He earned the B.S. in Zoology from Duke University where his area of concentration was in History of Science. In addition to serving as Assistant Professor of Environmental Studies at the Emory College of Emory University in Atlanta, Georgia, Dr. Pritchard serves as National Director of Outreach and as Associate Director of the Evangelical Environmental Network. He has also served as a Science Officer for the Land Use-Cover Change Project of the International Geosphere-Biosphere Programme and the International Human Dimensions of Global Environmental Change Programme of the U.N. He has published numerous articles on the science and ethics of environmental issues in peer-reviewed journals.


Dr. Roy W. Spencer is a Principal Research Scientist at the University of Alabama in Huntsville where he directs a variety of climate research projects. He received his Ph.D. in Meteorology from the University of Wisconsin in 1981, and was formerly a Senior Scientist for Climate Studies at NASA. Dr. Spencer also serves as the U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer for EOS flying on NASA's Aqua Satellite. He is co-developer of the original satellite method for precise monitoring of global temperatures from Earth-orbiting satellites, for which he received NASA's Medal for Exceptional Scientific Achievement. He has authored numerous climate research articles in scientific journals, and has provided congressional testimony several times on the subject of global warming.
