He is now a Principal Research Scientist at the University of Alabama in Huntsville and a Policy Advisor to The Heartland Institute.
Dr. Spencer’s work with NASA continues as the U.S. Science Team leader for the Advanced Microwave Scanning Radiometer flying on NASA’s Aqua satellite. His diligent work on tracking the planet’s temperature provided a tamper-proof source of data with which to test predictions of man-made global warming. He has provided congressional testimony several times on the subject of global warming.

Dr. Spencer is the author of two popular books on the global warming debate, Climate Confusion: How Global Warming Hysteria Leads to Bad Science, Pandering Politicians and Misguided Policies That Hurt the Poor (2008) and The Great Global Warming Blunder: How Mother Nature Fooled the World’s Top Climate Scientists (2010), both published by Encounter Books.
Dr. Spencer has made no secret of his evangelical faith, making him a model and inspiration for other scientists and evangelicals alike. He has been a senior advisor to The Cornwall Alliance for the Stewardship of Creation since its founding in 2005.
Dr. Spencer received his Ph.D. in meteorology at the University of Wisconsin-Madison in 1981.
Dr. Spencer’s research has been entirely supported by U.S. government agencies: NASA, NOAA, and DOE. He has never been asked by any oil company to perform any kind of service. Not even Exxon-Mobil.
