I do have an open mind about climate change, but let's face it: John Coleman is not a degreed meteorologist or climatologist. He was trained in Journalism, enjoyed a career as a tv "weatherman", and appears to be an great business man (since he started The Weather Channel).  He wouldn't even be qualified to work for The Weather Channel as a "meteorologist" today if he were to apply for a job there.  He doesn't meet the educational requirements. He has no knowledge of climatology, and can't speak the language of science.  He needs to leave the scientific analyses up to those trained in the atmospheric sciences, especially those with advanced degrees and understand the mathematics and physics of the atmosphere and climate variability. 

Relying on this man for a climatological summary of the past 300,000 years amounts to asking a plumber to replace your roof.
