"𝐓𝐡𝐞 𝟗𝟕% 𝐂𝐨𝐧𝐬𝐞𝐧𝐬𝐮𝐬 𝐌𝐲𝐭𝐡 𝐃𝐞𝐛𝐮𝐧𝐤𝐞𝐝
One of the most pervasive myths in science is that 97% (or sometimes stated as >99%) of “climate scientists” agree that all global warming since the mid-19th century is human-caused and that this warming is an existential threat to the welfare of the planet and all life on it.
Except, this statistic is largely made up, and no matter how many times it is quashed, it persists as a talking point in online forums.
The “consensus of scientists” is not organic. Rather, it was manufactured through questionable methods in two studies, both published in Environmental Research Letters (ERL): Cook et al. (2013) and Lynas et al. (2021).
Let's look closer at these studies.
𝐓𝐇𝐄 “𝟗𝟕% 𝐂𝐎𝐍𝐄𝐒𝐍𝐒𝐔𝐒”
The paper that got this all started was published in ERL in 2013.
https://iopscience.iop.org/article/10.1088/1748-9326/8/2/024024
Led by cognitive psychologist John Cook—a Senior Research Fellow at the Melbourne Centre for Behaviour Change and founder of the climate blog, Skeptical Science—he and eight co-authors skimmed the abstracts of 11,944 climate-related papers published between 1991 and 2011.
Of the 11,944 abstracts, a total of 7,930 (66.4%) of them expressed 𝒏𝒐 𝒑𝒐𝒔𝒊𝒕𝒊𝒐𝒏 on the cause(s) of global warming since the pre-industrial era.
Of the remaining 4,014 abstracts that endorsed either anthropogenic global warming (AGW) or natural global warming, 3,896 (97.1%) endorsed AGW in at least some capacity, while 78 (1.9%) questioned or rejected AGW. The remaining 40 (1%) of papers expressed uncertainty.
But, it gets even more nuanced than that if we look at the abstracts and pick them apart. On whether global warming is being caused entirely by human activities, by nature, or by a combination of both, of those 4,014 papers, they state warming is caused:
Entirely by humans: 64 papers (1.59%)
>>50% by humans: 922 (22.96%)
Equally natural + man-made: 2,910 (72.50%)
>>50% by natural cycles: 54 (1.35%)
Man is causing no warming: 24 (0.60%)
Don't know: 40 (1.00%)
So, a “97% consensus” can be contrived by either (a) omitting the 7,930 (66.4% of) abstracts in the 11,944-paper sample that did not explicitly state a position on the drivers of global warming, or by (b) lumping all 3,896 abstracts that endorsed at least some anthropogenic component as entirely endorsing AGW.
Either way, that's sausage-making.
But, what about the >99% consensus?
𝐓𝐇𝐄 “>𝟗𝟗% 𝐂𝐎𝐍𝐄𝐒𝐍𝐒𝐔𝐒”
Like Cook et al. (2013), Lynas et al. (2021) attempted to quantify the consensus on AGW.
https://iopscience.iop.org/article/10.1088/1748-9326/ac2966
In this synthesis, 3,000 climate papers were selected at random. In that batch, 282 were marked as false positives since they weren't actually climate-related. That’s fair. So, the analysis continued with the remaining 2,718 peer-reviewed articles.
Of those, 1,869 (68.8%) of them took 𝒏𝒐 𝒑𝒐𝒔𝒊𝒕𝒊𝒐𝒏 on AGW. And, like Cook et al. (2013), all 1,869 papers neither endorsing nor rejecting AGW were discarded. Of the remaining 849 papers that did endorse a position, 845 (99.5%) of them sided with AGW while four did not.
So, like Cook et al. (2013), Lynas et al. (2021) ignored over 65% of the papers selected that didn't take one position or the other on the physical driver(s) of global warming. By doing this, the authors could artificially manufacture a consensus on an issue where none actually existed if all of the relevant papers were considered.
The advantage that Lynas et al. (2021) has over Cook et al. (2013) is that each paper was examined thoroughly rather than just the abstract. This made for a more thorough analysis despite the same flawed methodology both used in ignoring the majority of papers that took a neutral stance.
𝐁𝐮𝐭, 𝐰𝐚𝐢𝐭, 𝐭𝐡𝐞𝐫𝐞'𝐬 𝐦𝐨𝐫𝐞. . .
Climate activists will argue that the authors of Cook et al. (2013) and Lynas et al. (2021) were justified in excluding the 66.4% and 68.8% of papers, respectively, that did not express a position, on the grounds that those studies did not focus on identifying or discussing causal links.
But, that's just hand-waving.
The fact is that not all of the studies endorsing AGW investigated the physical driver(s) of temperature change since 1850. In fact, in order to qualify as endorsing (or rejecting) AGW, a paper merely needed to take a stance on the issue, regardless of whether or not the study's focus was on the physical drivers of climate change.
You will find when reading through the literature that even papers challenging the conventional narrative—such as on topics like climate model performance, trends in extreme weather, and/or the efficacy of “net zero” policies—almost always include the disclaimer that mankind's carbon dioxide (CO₂) emissions are the proximate cause of all global warming. This is done so that the paper satisfies reviewers and journal editors enough to get accepted for publication. This is the science equivalent of a land acknowledgement to be in good standing with gatekeepers.
Another point I should add about Cook et al. (2013) and Lynas et al. (2021) is that neither paper frame their findings as being a reflection of the “consensus of scientists.” So, when climate activists claim that 97-99% of experts agree, that's not accurately stating what these studies purport.

(2021) is that neither paper frame their findings as being a reflection of the “consensus of scientists.” So, when climate activists claim that 97-99% of experts agree, that's not at all an accurate framing of these papers' findings.
The papers actually attempted to quantify the “scientific consensus” on AGW, which is a consensus of what the published literature says. That is different from a “consensus of scientists,” which is essentially nothing more than an expert opinion poll.
What's more, neither of these reviews addressed the million-dollar question, which is whether or not global warming has been [or will be] dangerous. Just because our GHG emissions 𝑚𝑎𝑦 have caused some [or even most of the warming] since the onset of the Industrial Revolution, that tells us nothing about the level of danger posed by it short- and long-term.
So, what do we actually know about what scientists think about (a) the cause(s) of global warming and (b) whether or not they think it is dangerous?
Thankfully, we have some insight into that.

While a “consensus of scientists” (i.e., expert opinion poll) is less robust than a “scientific consensus” (i.e., synthesis of published literature), one advantage that polling scientists for their opinion has over the latter is that it gives them anonymity to express their views on the issue without having to fear losing their job or having their paper(s) rejected by biased journal editors (the gatekeepers).
Prestigious, lauded scientific organizations such as the American Geophysical Union (AGU), the American Meteorological Society (AMS), and the Royal Society have manufactured a “consensus of scientists” by taking a very strong stance on the climate issue without first consulting their members for their views.
Both the AGU and AMS recently did just that following the Trump administration's decision to repeal the Obama-era 2009 Endangerment Finding that allowed the EPA to regulate tailpipe emissions.
From the AGU,

https://fromtheprow.agu.org/agu-denounces-trump-administrations-repeal-of-the-epa-endangerment-finding/
And, from the AMS,
“𝑇ℎ𝑒 𝐴𝑚𝑒𝑟𝑖𝑐𝑎𝑛 𝑀𝑒𝑡𝑒𝑜𝑟𝑜𝑙𝑜𝑔𝑖𝑐𝑎𝑙 𝑆𝑜𝑐𝑖𝑒𝑡𝑦 (𝐴𝑀𝑆) 𝑖𝑠 𝑑𝑒𝑒𝑝𝑙𝑦 𝑐𝑜𝑛𝑐𝑒𝑟𝑛𝑒𝑑 𝑏𝑦 𝑡ℎ𝑒 𝑟𝑒𝑝𝑒𝑎𝑙 𝑜𝑓 𝐸𝑃𝐴’𝑠 2009 𝐸𝑛𝑑𝑎𝑛𝑔𝑒𝑟𝑚𝑒𝑛𝑡 𝐹𝑖𝑛𝑑𝑖𝑛𝑔, 𝑤ℎ𝑖𝑐ℎ 𝑐𝑜𝑟𝑟𝑒𝑐𝑡𝑙𝑦 𝑐𝑜𝑛𝑐𝑙𝑢𝑑𝑒𝑑 𝑡ℎ𝑎𝑡 𝑔𝑟𝑒𝑒𝑛ℎ𝑜𝑢𝑠𝑒 𝑔𝑎𝑠 𝑒𝑚𝑖𝑠𝑠𝑖𝑜𝑛𝑠 ℎ𝑎𝑟𝑚 ℎ𝑒𝑎𝑙𝑡ℎ 𝑎𝑛𝑑 𝑤𝑒𝑙𝑙-𝑏𝑒𝑖𝑛𝑔 𝑓𝑜𝑟 𝑐𝑢𝑟𝑟𝑒𝑛𝑡 𝑎𝑛𝑑 𝑓𝑢𝑡𝑢𝑟𝑒 𝑔𝑒𝑛𝑒𝑟𝑎𝑡𝑖𝑜𝑛𝑠.”
The letter continues, asserting without presenting a single shred of evidence, that,

Both statements were written without consultation of each organization's professional members.
Contrary to the AMS' partisan take, we actually have good insight into what their members think about (a) the cause(s) of global warming and (b) whether or not they think warming is dangerous.
In January 2016, Dr. Ed Maibach and colleagues from George Mason University (GMU) polled all 7,682 (at that time) professional members of the AMS on their views on climate change. A handful of questions were asked with several follow-ups.
https://gmuchss.az1.qualtrics.com/CP/File.php?F=F_cRR9lW0HjZaiVV3
The survey had a 53.3% participation rate and there were 4,092 respondents (p. 1).
Here are a sample of the questions asked:

So, based on this 2016 survey of professional AMS members, of those who responded,
• 96% of AMS members agree that climate change is occurring, regardless of the proximate cause.
• 67% of AMS members agree that change has primarily been human-caused, but the contribution estimates vary considerably. 67% is far from a consensus given that 33% have a different opinion.
• 38% of AMS members agree that the impacts of climate change in their localities have been negative over the last 50 years. However, 40% said that the impacts have been mixed or primarily beneficial, and 21% said that they weren't sure.
So, what can we truly conclude about the “consensus of scientists” on climate change?
• Is climate change occurring?
• Human activities contribute to global warming in at least 𝑺𝑶𝑴𝑬 capacity?
• Climate change is [or will be] dangerous?
And, this exactly summarizes my position (despite the constant framing by detractors that I'm a “denier”). It also matches fairly closely with the abstracts in Cook et al. (2013) once you categorize the papers' findings correctly and account for nuance.
Thus, just because global warming is real and we do play some role in causing it is still not a good enough justification to rapidly eliminate fossil fuels from our energy mix. There must be sufficient proof that this warming poses a great threat to the welfare of the planet and life on it, and that has yet to be provided contrary to the BS-infused letters written by the AGU and AMS last week.
So, when climate alarmists [most of whom have no qualifications of their own] claim that I am standing at odds with organizations like the AMS or NASA, quite frankly, I don't care.
It is clear from the survey results above that there is a greater disagreement among scientists than you are led to believe by what both the gatekeepers allow to be published in journals and what higher-ups within scientific organizations claim is the universal position among their members.
Government and university research scientists also are often told what they can and cannot say publicly about climate change. I know that for a fact because I have family that are federal employees, and I know quite a few skeptics in academia at different colleges / universities that play the game to avoid being fired, but in reality, don't agree with alarmist messaging in the slightest.
Last, but not least, consensus isn't science.
Science requires one investigator who happens to have verifiable data and evidence."
