The theory of Anthropogenic Global Warming is regularly presented as benefiting from a solid scientific consensus. What proves the solidity of this consensus? A scientific article, published in 2016  by Cook and colleagues, proposed a synthesis of the work: from the examination of  studies available at that time, the authors showed that the consensus on the reality of climate change was shared by 90%-100% of scientific climate experts. An estimate that we find widely relayed in the media today. In 2019, Powell said he found consensus to be 100%. In this article, we propose to analyze the potential biases in the work of Cook and colleagues, in order to understand how these biases could affect the claimed level of consensus. We also deal with Powell’s recent assert of 100% consensus and enlighten potential cognitive & methodological biases in his approach.

AN UNDENIABLE CONSENSUS?
