"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.
iopscience.iop.org/article/10.108
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.
iopscience.iop.org/article/10.108
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,

fromtheprow.agu.org/agu-denounces-
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.

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."

Wow. Kinda like the "science" on LGBTQ issues! Or "gun violence" issues. Or "Trump is a con man" issues. No legit substance behind any of it.
The problem is that the narrative gets pushed by the MSM and everyone uncritically believes what they’re told.
Wading through your less-than-rational/less-than-scientifically-rigorous claims, starting at the top:
Reilly is a professor and author, Martz is a meteorologist, and speaker. They seem more qualified to discuss this than anyone who might comment.
You've cited the opinions of a recent college graduate, Martz, who is ~23 years old and just out of college, who is trying to establish himself as someone who claims to disagree with the scientific and meteorological community by disagreeing with the apparent consensus on climate change. I see no link to anything by a "Reilly."
Not off to a strong start. But are you suggesting that this college grad with a bachelors degree has "discovered" something that contradicts people who've been in the field for years/decades? That's quite a claim. Why do we trust this one apparent outlier kid, just out of college? Did you have a wise and seasoned handle on your field when you were ONE YEAR out of college with your bachelors degree?
Do you see how that might sound presumptuous and a bit like you're claiming more than you've earned?
This young college grad says:
"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”"
"Conesnsus." Off to a great start. Not to be too harsh, though. That is to be expected from a perhaps not exceptional recent college grad taking his "research" to that bastion of scientific study, "X." But where is his research?
On the other hand, over and against this recent college grad with his bachelors' degree and one year of "meteorology..." experience?
https://www.npr.org/2025/09/02/nx-s1-5521384/energy-report-scientists-climate-change
Before going further, it might help if you clarify your personal, non-climate-expert opinion: Are you suggesting that climate change is NOT influenced by human policy/actions?
Or do you agree that humans have negatively impacted out climate, you're just wondering if a full 97% of experts in the field agree with that or the degree of human impact?
Given what we know, I see no definitive evidence that human life is the primary driver of climate variation. We’ve had periods of warmer, periods of colder, before industrialization.
Could it be a factor, maybe. But given the glaring lack of the disastrous consequences predicted, I’m skeptical.
If 100% objective proof exists, cool. But if it did, I suspect it’d be well known by now.
I’m saying that the 97% consensus has always been BS, he’s just pulled evidence together and presented it in a way that makes sense.
Your ad hom attacks are tiresome and boring. If you have proof the data is wrong, bring that.
I've been doing some searches to try to find out who young Mr Martz is and WHERE he is a "meteorologist." I can't find that he's employed as a meteorologist anywhere. It appears he graduated with his bachelors in "meteorology" last year sometime (or the year before??). His own website has NO "about me" or credentials listed and I can find nothing that affirms he even has a degree, just his claim, much less a job in "meteorology."
Further, having a bachelors degree in meteorology is not the same as being an expert in climate science. Do you understand the difference? From one source:
"The major difference between meteorologists and climatologists is that meteorologists predict weather for the near term, while climatologists study past weather patterns to predict trends."
So, IF this young man and recent graduate is truly a "meteorologist," that does not necessarily make him an expert on climate concerns.
Am I mistaken?
Still don't know who "Reilly" is? The Smoking Man?
Ohhhhhhhh goooody, more ad hom attacks. I do so looooove a good ad hom attack.
Especially when it’s you attacking the credentials of someone who’s clearly more expert than yourself.
It’s hilarious that Dan is frantically trying to discredit someone based on age and education, instead of demonstrating that the data is wrong.
The problem with the 97% myth has always been (much like the 9/11 Truther report), that they included “scientists” with no background in climate science as if they were experts.
Is it an ad hom attack to note that a 23 year old young man who claims to be a meteorologist is not the same as being a climatologist? Or just a fact?
Is it reasonable to ask what a young man's credentials and experience is in a field he's making claims about?
Do you think this young man is as emotionally fragile as you are to someone simply asking reasonable questions?
Dan
In this context, because you’re attacking him personally and not the data, yeah it pretty much is.
All you’ve done is bitch about him, with no mention of the accuracy of the data.
I was unaware that being a climatologist qualified you to analyze data in previously published research?
It’s a meta analysis of the study data not of the climate data.
Nice excuse.
I've made no "attacks." I've raised reasonable questions about this young man's credentials and how he actually is.
Only in the MAGA world of hyper-sensitive, emotionally fragile people scared of questions is that an "attack."
Nor have I "bitched" about him. I've asked reasonable questions.
Why do you all wilt so cowardly in the face of simple reasonable questions?
You’ve focused entirely on his age and what you perceive as his educational deficiencies.
If I remember correctly the ad hom fallacy is going after the person, not the substance.
If you want to quibble about “attack” and semantics, you do you.
Either the data is accurate or it’s not.
The only cowardice is you not engaging the data, but choosing the ad hom instead.
"Why do you all wilt so cowardly in the face of simple reasonable questions?"
They're not "reasonable" in this context at all. Let's say he never went to school and was totally self-taught. Now what? Is the data accurate or not? He is hardly the only person alive making the same arguments against the climate alarmist con men.
No one is wilting, and your questions aren't reasonable just because you say so.
As I was scrolling down this post I was struck by the number of pieces of data it contained. Statistics, links, and analysis. Yet all Dan can focus on is the author's age, and perceived lack of credentials. The real question might well be why Dan wilts so cowardly in the face of lots of data.
I've posted this link before but Dan refuses to acknowledge the truth from all the many sources I cite. There has ben no evidence at all that mankind can change the weather and tons of evidence that the climate change claims are all bogus.
https://agotoblog.blogspot.com/2015/08/global-climate-change-nonsense.html
I began with the young man/recent graduate (and would it surprise anyone if he turned out to be a christian conservative, as well??) because I was walking methodically through the link/data you provided. And because I know, as we see in this NASA report, that NASA and a whole host of other scientific groups
(including the AMA,
the U.S. National Academy of Sciences
AND the American Meteorological Society, ie, meteorologists, as this young man hopes to be one day)
...all these scientific groups endorse the conclusions of the 2012 (and a later, 2021 update) on the science that says that climate change is real and that anthropogenic causes are a/the primary factor leading to the reality of climate change.
https://science.nasa.gov/climate-change/scientific-consensus/
Given that wide range of scientific and specifically climatologist opinion saying just that, AND given this young man bravely standing alone, just outside of his college graduation, the question MUST be asked:
Given the complicated, highly scientific data involved and the difficulty of understand all the moving parts, is it more reasonable to assume that this one young graduate has discovered something that ALL these other seasoned experts in a range of fields, including his own field of meteorology and in the actual field o climatology...?
Or is it more reasonable to think that he may simply be mistaken?
Now, to be sure, the scientific method would highly encourage this young man to test his theories and try to prove them in a replicable, controlled setting and manner. The actual scientists involved ARE always glad to change opinions when better data comes along.
But what are the odds?
That's why it's important and reasonable to begin with the reporter and the trustworthiness of the reporter.
IF we just believe what any old fool says, then an amateur videographer could show up outside a day care, record NO children in the building, and then start making claims "These Somalis are ripping people off!! only to find out that he was simply mistaken for a variety of reasons. And IF he were part of a journalistic outfit with integrity and processes of verification, it would never have been reported. But he wasn't. Just a fool with a camera.
OR, if some gov't official sees a video of officers under her charge kill a man in broad daylight and that official says, "That man was a terrorist and caused his own death!", it's reasonable to ask "Is this an official we can trust? Or does she have a record of making stupidly false claims and is not an expert with sufficient experience in the field to run the office like an adult.
It's always appropriate to begin looking into a claim with "What is the credibility of the person making the claim?" And to also include: What do OTHER experts (or actual experts) have to say?
What NASA said:
t’s important to remember that scientists always focus on the evidence, not on opinions. Scientific evidence continues to show that human activities (primarily the human burning of fossil fuels) have warmed Earth’s surface and its ocean basins, which in turn have continued to impact Earth’s climate. This is based on over a century of scientific evidence forming the structural backbone of today's civilization.
NASA Global Climate Change presents the state of scientific knowledge about climate change while highlighting the role NASA plays in better understanding our home planet. This effort includes citing multiple peer-reviewed studies from research groups across the world,1 illustrating the accuracy and consensus of research results (in this case, the scientific consensus on climate change) consistent with NASA’s scientific research portfolio.
With that said, multiple studies published in peer-reviewed scientific journals1 show that climate-warming trends over the past century are extremely likely due to human activities. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position. The following is a partial list of these organizations, along with links to their published statements and a selection of related resources.
But maybe this young man, standing by himself, HAS discovered something to the contrary. I would encourage him to run research to support or disprove his own theory.
Here's Harvard reporting on this latest 2021 report:
We conclude with high statistical confidence that the scientific consensus on human-caused contemporary climate change-expressed as a proportion of the total publications-exceeds 99% in the peer reviewed scientific literature.
https://ui.adsabs.harvard.edu/abs/2021ERL....16k4005L/abstract
Cornell:
More than 99.9% of peer-reviewed scientific papers agree that climate change is mainly caused by humans, according to a new survey of 88,125 climate-related studies.
https://news.cornell.edu/stories/2021/10/more-999-studies-agree-humans-caused-climate-change
The IPCC, to which this young graduate says he'll be issuing some statement this year. We'll see how that goes.
https://www.ipcc.ch/2021/08/09/ar6-wg1-20210809-pr/
And the people who issued the latest report in 2021, themselves:
In addition to analyzing the raw survey results, we independently quantify how many publications self-identified climate experts published in the field of climate change research and compare that to their survey response on questions about climate change. As well as a binary approach classifying someone as ‘expert’ or ‘non-expert’, we also look at expertise as a scale. We find that agreement on anthropogenic global warming is high (91% to 100%) and generally increases with expertise. Out of a group of 153 independently confirmed climate experts, 98.7% of those scientists indicated that the Earth is getting warmer mostly because of human activity such as burning fossil fuels.
Among those with the HIGHEST LEVEL of expertise (independently confirmed climate experts who each published 20+ peer reviewed papers on climate change between 2015 and 2019) there was 100% agreement that the Earth is warming mostly because of human activity.

So, if this young man can prove otherwise, let him do his research HAVE OTHER independent scientists confirm it. Then we'll talk.
Solo claims are not that impressive.
So you started with the irrelevant, ad hom crap. Gotcha.
The more you blather, the more I doubt that you actually read the post.
The post is concerned with the 97% myth and whether or not it is accurate.
But you choose to argue something else entirely.
I do so enjoy it when you just make shit up out of whole cloth and act as if your made up shit is real.
Of course, that means we should start with your credibility. Which isn't awesome.
Yet none of those things demonstrates that the DATA he cited is wrong. The existence of contrary DATA doesn't magically prove that your (likely) cherry picked DATA is automatically right.
Given the massive increase of scientific fraud in the "peer review" process, it seems a bit naive to ignore the influence of funding, power, prestige, and money on scientists.
C'mon Glenn, you know that Dan isn't going to pay attention to any experts that don't prop up his narrative.
Upon who's "science" is this NASA report relying? Does NASA digging it make it true?
Dan's last quote is wildly nonsensical. It claims humans have more affect on climate than the sun. It's abjectly idiotic. Global warming entirely caused by human activity? That's stupid on its face.
Great question. Given the fact that all NASA is at this point is support for Space X, and other private companies, I'm not sure that NASA has the cachet that it used to.
I just saw a video that I'll try to fine which looked at what was learned from an ice core in Greenland from thousands of years ago, and the conclusions were that the earth was warmer then, and somehow managed to survive. I'll try to find it at some point.
