    Regarding the Roy Spencer paper:

    “Misdiagnosis of Surface Temperature Feedback”

    Filed under: Climate Science— mike @ 29 July 2011

    Guest commentary by Kevin Trenberth and John Fasullo

    The hype surrounding a new paper by Roy Spencer and Danny Braswell is impressive (see for instance Fox News); unfortunately the paper itself is not. News releases and blogs on climate denier web sites have publicized the claim from the paper’s news release that “Climate models get energy balance wrong, make too hot forecasts of global warming”. The paper has been published in a journal called Remote sensing which is a fine journal for geographers, but it does not deal with atmospheric and climate science, and it is evident that this paper did not get an adequate peer review. It should not have been published.

    The paper’s title “On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth’s Radiant Energy Balance” is provocative and should have raised red flags with the editors. The basic material in the paper has very basic shortcomings because no statistical significance of results, error bars or uncertainties are given either in the figures or discussed in the text. Moreover the description of methods of what was done is not sufficient to be able to replicate results. As a first step, some quick checks have been made to see whether results can be replicated and we find some points of contention.

    ...

    Even so, the Spencer interpretation has no merit. The interannual global temperature variations were not radiatively forced, as claimed for the 2000s, and therefore cannot be used to say anything about climate sensitivity. Clouds are not a forcing of the climate system (except for the small portion related to human related aerosol effects, which have a small effect on clouds). Clouds mainly occur because of weather systems (e.g., warm air rises and produces convection, and so on); they do not cause the weather systems. Clouds may provide feedbacks on the weather systems. Spencer has made this error of confounding forcing and feedback before and it leads to a misinterpretation of his results.

    The bottom line is that there is NO merit whatsoever in this paper. It turns out that Spencer and Braswell have an almost perfect title for their paper: “the misdiagnosis of surface temperature feedbacks from variations in the Earth’s Radiant Energy Balance” (leaving out the “On”).

    OMG, whatever will the Hootie do? What is his fate? Will he flap his wings to cool the globe? Will he merely sit on his tree and sound the alarm until he is ultimately cooked?

    Stay tuned for the next installment of Hootie Sounds The Alarm,,,,,,,,,,,,,,Again!

    Kevin Trenberth and John Fasullo have to make those boat payments, so they can't let anything threaten their gravy train.
    "Our president delivered his State of the Union message to Congress. That is one of the things his contract calls for -- to tell congress the condition of the country. This message, as I say, is to Congress. The rest of the people know the condition of the country, for they live in it, but Congress has no idea what is going on in America, so the president has to tell 'em." ~ Will Rogers
