The usual denialists (e.g. The Register) are excited because some guy they never heard of before has joined Inhofe’s merry band, writing:

“I appreciate the opportunity to add my name to those who disagree that global warming is man made.”

M. J. Murphy has some information about Theon. It seems that Inhofe’s claim that Theon was Hansen’s supervisor is completely untrue:

Theon wrote to the Minority Office at the Environment and Public Works Committee on January 15, 2009. “I was, in effect, Hansen’s supervisor because I had to justify his funding, allocate his resources, and evaluate his results. I did not have the authority to give him his annual performance evaluation…

Read the last bit closely. Being “in effect” Hansen’s supervisor is here contrasted with being “in reality” Hansen’s supervisor–being the guy who gives Hansen his annual performance appraisal, in other words–which, frankly, does linguistic violence to the term.

Gavin Schmidt writes:

Dr. Theon appears to have retired from NASA in 1994, some 15 years ago. Until yesterday I had never heard of him (despite working with and for NASA for the last 13 years). His insights into both modelling and publicity appear to date from then, rather than any recent events. He was not Hansen’s ‘boss’ (the director of GISS reports to the director of GSFC, who reports to the NASA Administrator). His “some scientists” quote is simply a smear – which scientists? where? what did they do? what data? what manipulation? This kind of thing plays well with Inhofe et al because it appears to add something to the ‘debate’, but in actual fact there is nothing here. Just vague, unsubstantiated accusations.

And Joe Romm finds some more misrepresentations in Inhofe’s press release:

So who is John S Theon? ? Deltoid

Newbies should review the thread before posting their poor attempts at BS.
It would the rest of us time save themselves from looking the fool.
