There were about 40-50 attendees at the seminar where he presented an effective and persuasive demonstration of that the IPCC models significantly overstated climate sensitivity to human climate forcings. He also showed how circulation features such as ENSO and the PDO can result in multi-year variations in the global surface temperatures. Climate Science will report on this further when Dr. Spencer publishes this very important research. Unfortunately, no one was present from the NCAR GCM modeling group [although his seminar was widely advertised].
