The 97 % consensus level from Cook et al. (2013) is the most prominent climate change consensus work often referenced as evidence for ‘science being united’ on anthropogenic global warming (AGW) – with greenhouse gases (GHG) being the major driver. This study takes a closer look by testing the Cook work resulting in the 97% consensus figure. This was done by conducting a mini analysis comparing the abstract based analysis utilized by the Cook team, and a new data-centered approach introduced by our team. The result of the analysis of 2707 published climate change papers from (September) 1991, 1995, 1999, 2009, 2019 demonstrate less data support for the GHG-AGW hypothesis contrary to consensus claims. Our result also shows the importance of a data-focused approach, (as opposed to abstract based analysis) in determining the true level of scientific support for AGW or any other specific scientific question.
