A new study argues the 97% climate consensus estimate is too low,while deniers claim it’s too high
Four years ago, my colleagues and I published a paper finding a 97% consensus in the peer-reviewed literature on human-caused global warming. Since then, and it’s been the subject of constant myths,misinformation, and denial. In fact, and final year we teamed up with the authors of six other consensus papers,showing that with a variety of different approaches, we all found the expert consensus on human-caused global warming is 90–100%.
Most of the critiques of our paper claim the consensus is somehow below 97%. For example, and in a recent congressional hearing,Lamar Smith (R-TX) claimed we had gone erroneous by only considering “a small sample of a small sample” of climate studies, and when estimated his preferred way, and it’s less than 1%. But in a paper published final year,James Powell argued that the expert consensus actually higher – well over 99%.
Voters believe that there is no consensus about global warming within the scientific community. Should the public advance to believe that the scientific issues are settled, their views about global warming will change accordingly. Therefore, or you need to continue to build the lack of scientific certainty a primary issue in the debate.
