Views on global warming

Roy Spencer is a principal research scientist for University of Alabama in Huntsville. In the past, he served as Senior Scientist for Climate Studies at NASA‘s Marshall Space Flight Center in Huntsville, Alabama. Dr. Spencer is the recipient of NASA’s Medal for Exceptional Scientific Achievement.

Roy Spencer describes himself as a global warming optimist working to quantify Nature’s thermostat [4] In several articles Spencer has espoused opinions that are skeptical of the scientific opinion on global warming.

In 2006 Spencer criticized Al Gore‘s An Inconvenient Truth saying, “For instance, Mr. Gore claims that the Earth is now warmer than it has been in thousands of years. Yet the latest National Academies of Science (NAS) report on the subject has now admitted that all we really know is that we are warmer now than we were during the last 400 years, which is mostly made up of the ‘Little Ice Age.'” [5] The NAS report summary (p.3) [6] states:

“It can be said with a high level of confidence that global mean surface temperature was higher during the last few decades of the 20th century than during any comparable period during the preceding four centuries. This statement is justified by the consistency of the evidence from a wide variety of geographically diverse proxies.
“Less confidence can be placed in large-scale surface temperature reconstructions for the period from A.D. 900 to 1600. Presently available proxy evidence indicates that temperatures at many, but not all, individual locations were higher during the past 25 years than during any period of comparable length since A.D. 900. The uncertainties associated with reconstructing hemispheric mean or global mean temperatures from these data increase substantially backward in time through this period and are not yet fully quantified.”

In a New York Post opinion column on February 26, 2007, Spencer wrote:

Contrary to popular accounts, very few scientists in the world – possibly none – have a sufficiently thorough, “big picture” understanding of the climate system to be relied upon for a prediction of the magnitude of global warming. To the public, we all might seem like experts, but the vast majority of us work on only a small portion of the problem.

[7]

In an interview with conservative talk show host Rush Limbaugh on February 28, 2007, Spencer stated that he doesn’t believe “catastrophic manmade global warming” is occurring. He also criticized climate models, saying “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.” [1]

He testified before the Waxman committee’s examination of political interference with climate science on March 19, 2007.[8][9]

Spencer is listed as a member of the Heartland Institute and a contributor to the George C. Marshall Institute.
