Sure, as soon as you provide equivalent evidence regarding those you have smeared - off the top of my head Wikipedia, scepticalscience.com, realclimate.com, the IPCC and some 20-plus national academies of sciences :roll:
My post above is an explanation of why I would not consider Dr. Roy Spencer to be an objective reliable source regarding other scientisists' views. As a general rule I don't approve of your frequent attack-the-source approach to debate, because ultimately it'd descend into the farce of neither side accepting anything the other offers and dismissing information simply because they don't like it (as you seemingly did regarding the source you yourself provided for CO2's logarithmic warming effect). But my comments were in response to
your post implying Dr. Spencer's credentials or reliability to be excellent and specifically downplaying association with oil companies.
My actual criticism of the graph, which you have not answered beyond posting Spencer's resume, was that "it's extremely dubious that any climate models can be accurately represented by a single thin line as all of those are." Take a look at
some IPCC projections for a variety of emissions scenarios, for example. Or
this graphic from "a draft of the Fifth Assessment Report" of the IPCC. Note that contrary to Dr. Spencer's graph, these projections (and I suspect
all serious climatologists' projections) recognise in their error margins or scope for uncertainty the variables which might not be so easily or completely accounted for. Indeed most of the observed temperature bars up to 2010 (a notable exception being 2008's remarkable low) do in fact fall within the range of those projections.
That's in stark contrast to Dr. Spencer's portrayal - perhaps because Dr. Spencer chose for his observational comparison tropical mid-troposphere temperatures, rather than surface or global averages? I really wouldn't know. I simply wanted to point out that posting that graph proved little or nothing, except perhaps to those already keen to dismiss the conclusions of most scientists.
