Bishop Hill’s Blog, via Climate Depot:
I really have been struggling to summon up much enthusiasm for the inanities of John Cook’s paper, but Brandon Schollenberger has written an extraordinary analysis of the data, which really has to be seen to be believed. Readers are no doubt aware that the paper involves rating abstracts of a whole bunch of research papers to see where they stand on the global warming question.
The guidelines for rating [the] abstracts show only the highest rating value blames the majority of global warming on humans. No other rating says how much humans contribute to global warming. The only time an abstract is rated as saying how much humans contribute to global warming is if it mentions:
that human activity is a dominant influence or has caused most of recent climate change (>50%).
If we use the system’s search feature for abstracts that meet this requirement, we get 65 results. That is 65, out of the 12,000+ examined abstracts. Not only is that value incredibly small, it is smaller than another value listed in the paper:
Reject AGW 0.7% (78)
Remembering AGW stands for anthropogenic global warming, or global warming caused by humans, take a minute to let that sink in. This study done by John Cook and others, praised by the President of the United States, found more scientific publications whose abstracts reject global warming than say humans are primarily to blame for it.
I’m speechless.
…some folks aren’t getting the significance of Schollenberger’s findings, using Cook’s own data and code, which have been shown to be replicable at Lucia’s comment thread, Schollenberger finds 65 that say AGW/human caused, but there’s 78 that reject AGW. Cook never reported that finding in the paper, thus becoming a lie of omission, because it blows the conclusion. Combine that with the lack of reporting of the 32.6%/66.1% ratio in Cook’s own blog post and media reports, and we have further lies of omission.
