Dr. Roy Spencer is a climatologist, author, blogger, former NASA scientist, and a Principal Research Scientist at the University of Alabama. He is also a climate change skeptic.

Spencer received his Ph.D. in meteorology from the University of Wisconsin-Madison in 1981.

Spencer worked in correlation with John Christy at NASA - acting as a Senior Scientist for Climate Studies monitoring global temperature via satellites. For that work he was awarded NASA’s Exceptional Scientific Achievement Medal.

He became a Principal Research Scientist at the University of Alabama in Huntsville in 2001.

His most popular book is "Climate Confusion" - a text on "how global warming hysteria leads to bad science, pandering politicians and misguided policies that hurt the poor."


Skeptical View on Climate Change

Dr. Spencer likes to call himself a "global warming optimist," attempting to scientifically prove any warming of the Earth is natural.

Therefore, he has spoken publicly, via blog, media, testifying before Congress, that the alarmist theory of global warming is not scientifically sound: "The people that have built the climate models that predict global warming believe they have sufficient physics in those models to predict the future. I believe they don't. I believe the climate system, the weather as it is today in the real world shows a stability that they do not yet have in those climate models." - Interview with Rush Limbaugh on February 28, 2007

He argues that the Earth is not sensitive to manmade greenhouse gas emissions.
