March 3, 2006: Climate Change & Open Lines - Dr. Roy Spencer
Podcast: The Art Bell ArchivePublished On: Wed Dec 24 2025
Description: Art Bell sits down with Dr. Roy Spencer, a principal research scientist at the University of Alabama in Huntsville and former NASA senior scientist, for a detailed examination of the global warming debate. Spencer acknowledges that at least half of recent warming is likely attributable to human activity but argues that climate models overestimate the sensitivity of the system to carbon dioxide, possibly by a factor of two or more.The discussion covers the dispute between Spencer and NASA scientist James Hansen, whose increasingly urgent warnings about climate change have put him at odds with the agency. Spencer explains the role of feedbacks in climate modeling, particularly how precipitation systems and water vapor may act as natural stabilizers that current models fail to capture. He also reveals that upcoming satellite data will largely resolve the long-standing discrepancy between surface thermometer readings and satellite temperature measurements.Art opens lines to callers who share their observations of rising sea levels, unusual underground tremors, and a deep intuitive sense that a profound environmental shift is approaching. Spencer weighs in on hurricane cycles, HAARP, and a promising Australian solar chimney technology that could rival coal-fired power plants.
