In a Nutshell

By -
A fundamental problem with the entire issue here is that climate science is 
not a classic, experimental science.  As an emerging science of a complex, 
chaotic climate system, it is plagued by uncertainty and ambiguity in both 
observations and theory.  Lacking classic, laboratory results, it easily 
becomes hostage to opinion, groupthink, arguments-from-authority, 
overstatement of confidence, and even Hollywood movies.  When climate 
scientists are placed in the limelight because this issue can generate 
compelling disaster scenarios, we simply don’t want to say, “We just don’t 
know.”
