Climate Misinformer: Roy Spencer

Dr. Roy Spencer is a principal research scientist for the University of Alabama in Huntsville, as well as the U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer (AMSR-E) on NASA’s Aqua satellite.  He is known for his work with the satellite-based temperature monitoring for which he and Dr. John Christy received NASA’s Exceptional Scientific Achievement Medal [Wikipedia]. 

Dr. Spencer suggests that global warming is mostly due to natural internal variability, and that the climate system is quite insensitive to humanity’s greenhouse gas emissions.

Other professional affiliations: Dr. Spencer is on the board of directors of the George C. Marshall Institute, a right-wing conservative think tank on scientific issues and public policy.  He listed as an expert for the Heartland Institute, a libertarian American public policy think tank.  Dr. Spencer is also listed as an expert by the International Climate and Environmental Change Assessment Project (ICECAP), a global warming "skeptic" organization [DeSmogBlog].
