Too funny: When I asked warmist Marshall Shepherd why he says the AGW signal emerged in 1850, while Stephen Schneider said the 1980s, he refuses to answer; tells me to try "publishing your thoughts in peer reviewed journal"

@DrShepherd2013 I'm still waiting for your answer: Did the AGW signal emerge in 1850 or the 1980s? http://tomnelson.blogspot.com/2013/05/serious-science-question-for-marshall.html …

@tan123I don't debate numerous theories on twitter, but encourage you to consider publishing your thoughts in peer reviewed journal. thx

Tom Nelson: Serious "settled science" question for Marshall Shepherd

How do you reconcile these two very different statements? If the alleged human-induced warming signal emerged from the noise in 1850, why did Schneider suggest that the signal didn't emerge until 130+ years later?
