The Intergovernmental Panel on Climate Change (IPCC) assumes that there are no long-term natural sources of energy imbalances in the Earth’s radiative budget that would cause natural periods of global warming or global cooling. But recent satellite evidence suggests that the Pacific Decadal Oscillation (PDO) does indeed change the Earth’s energy balance. When that PDO-related forcing is put into a simple climate model, along with the 100-year history of the PDO, a global temperature history results which is very similar to that observed, including 75% of the centennial temperature trend. This suggests that the IPCC’s claim of high confidence in global warming being manmade is misplaced.

Dr. Roy Spencer is a principal research scientist for University of Alabama in Huntsville. In the past, he has served as Senior Scientist for Climate Studies at NASA’s Marshall Space Flight Center in Huntsville, Alabama, where here he directed research into the development and application of satellite passive microwave remote sensing techniques for measuring global temperature, water vapor, and precipitation. He currently is the U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer (AMSR-E) on NASA’s Aqua satellite. Dr. Spencer is the recipient of NASA’s Medal for Exceptional Scientific Achievement and the American Meteorological Society’s Special Award for his satellite-based temperature monitoring work. He is the author of numerous scientific articles that have appeared in Science, Nature, Journal of Climate, Monthly Weather Review, Journal of Atmospheric and Oceanic Technology, Journal of Climate and Applied Meteorology, Remote Sensing Reviews, Advances in Space Research, and Climatic Change. Dr. Spencer received his Ph.D. in Meteorology from the University of Wisconsin in 1981.
