Spencer, a former senior NASA climatologist, reveals how climate researchers have been duped by Mother Nature into believing the Earth's climate system is far more sensitive to human activities and carbon dioxide than it really is.

Roy W. Spencer is a Principal Research Scientist at the University of Alabama in Huntsville. He was formerly a Senior Scientist for Climate Studies at NASA. He is co-developer of the original satellite method for precise monitoring of global temperatures from Earth-orbiting satellites. He has provided congressional testimony several times on the subject of global warming and authored the 2008 New York Times bestseller, Climate Confusion.
