At "The Consensus Project" you can search for abstracts to various papers yourself to assess whether these papers should be placed in the correct group of papers or not.
There, you can search for various key terms, and specifying the qualifications for the search, such as the year of publication, and select the endorsement level to which the paper allegedly supports Anthropogenic Global Warming.
While I was searching, I came across a peculiar paper that was placed in the second Category. This category "explicitly endorses but does not quantify Anthropogenic Global Warming."
The search I put in was "cosmic rays" and I wanted to see which papers would pop up in the second category which allegedly housed papers that supported Anthropogenic Global Warming.
One result popped up, and it was a very surprising result.
The paper was titled "On climate response to changes in the cosmic ray flux and radiative budget" and concludes that,
"Subject to the above caveats and those described in the text, the CRF/climate link therefore implies that the increased solar luminosity and reduced CRF over the previous century should have contributed a warming of 0.47 ± 0.19°K, while the rest should be mainly attributed to anthropogenic causes. Without any effect of cosmic rays, the increase in solar luminosity would correspond to an increased temperature of 0.16 ± 0.04°K."
How at all does this endorse Anthropogenic Global Warming when it concludes that over half of the 0.7 Degree C warming observed over the 20th Century can be explained by Solar Luminosity and the Cosmic Ray Flux?
This find not only casts doubt on John Cook's methodologies, but it also raises questions about how many other papers are incorrectly placed in John Cook's study.
Additional research has further revealed that there are more skeptical papers that are classified as "neutral" papers, thus raising the question with regard to how many papers actually support Cook's view of Anthropogenic Global Warming.
This increases doubts about how many of the alleged papers that were classified as supporting Anthropogenic Global Warming actually do support Anthropogenic Global Warming.
