Dessler on the Joe Rogan Experience…Oy!

One of our favorite Climate ScientistsTM, Andrew Dessler recently appeared on the Joe Rogan Experience. I believe it was the Katastraphic Klimate Konsensus’s response to the transgression of previously allowing Dr. Steve Koonin to appear.

Some reactions on non-climate Twitter may not be what he was hoping for.



MasterResource has another excellent article on Dessler’s behavior

By Robert Bradley Jr. — February 17, 2022

[Andrew] Dessler said anyone arguing that the science is too uncertain isn’t arguing from a legitimate position…. “[Koonin]’s a climate flat earther.” (Quoted in Benjamin Thorp, October 18, 2021).

“Dumb arguments” is too harsh? He’s just a old white dude whose vast experience in the halls of power gives him a unique ability to point out the errors that other people make? Nope. (Andrew Dessler, October 14, 2021)

Andrew Dessler, a climatologist at Texas A&M University, will have nothing to do with any critics of climate alarm. This activist has pure scorn toward his intellectual and scientific doubters. “Angry Andy” is certain that climate science is settled and drop-everything alarming.

deep ecologist (nature is optimal and fragile; human interference cannot be good), Dessler has long concluded that we are headed for (or already in) a climate dystopia. Any fair hearing of the less extreme view of global lukewarming/CO2 benefits would be a leak in the dike, one that could expand and take down the Wall of Climate Gloom.

But for now, the cancel culture is at work with climate science in particular. Michael Mann (Dessler’s colleague in arms) put it this way:

All of the noise right now from the climate change denial machine, the bots & trolls, the calls for fake ‘debates’, etc. Ignore it all. Deniers are desperate for oxygen in a mainstream media environment that thankfully is no longer giving it to them.

Report, block. Don’t engage.

Imagine an open-minded young person considering a career in climatology. He or she wants to really wants to probe the look-the-other-way areas of uncertainty with climate-feedback physics and with climate models. Seek and expand the frontiers of knowledge under the highest standards of the scientific method. Show professionalism and respect for the views of colleagues and others. Experience politeness and social skills, given and received.

That person best not enter into a profession where an Andrew Dessler or a Michael Mann or a John Holdren would sneer and blackball. Remember what Mann said about Judith Curry in Climategate: “I gave up on Judith Curry a while ago. I don’t know what she thinks she’s doing, but it’s not helping the cause, or her professional credibility.” Cancel Culture 101.

Steven Koonin

Enter Steven E. Koonin, University Professor at New York University. This noted theoretical physicist is author of the best-seller: Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters (2021). Having taught theoretical physics at the California Institute of Technology for most of his career, Koonin went on to work for BP (new technologies) and then as Obama’s Undersecretary for Science in the U.S. Department of Energy. In this position, Koonin oversaw climate research and energy technology work.

Koonin has a BS in Physics from Caltech and a PhD in Theoretical Physics from MIT. A specialist in modelling complexity, Koonin wrote the classic 1985 textbook Computational Physics.

Koonin is author of 200 peer-reviewed papers in the fields of physics and astrophysics, scientific computation, energy technology and policy, and climate science, as well as having been lead author on multiple book-length reports, including two National Academies studies.

In short, Steve Koonin is a leader in his field and well respected. And, it turns out, he is honest and of an age and tenure where he can speak truth to power.

Dessler’s Smears

Here is Dessler on Koonin:

I actually hate to weigh in on Koonin’s book …. Here are a few thoughts. First, Koonin has a track record of making dumb, over the top, exaggerated arguments.

Second, his facts are carefully cherry picked to present a specific narrative. For example, he says heat waves in the U.S. were more severe in the 1930s than today. OK, but the U.S. covers 2% of the planet. Globally, heat waves are more severe today.

Also, his belief in models is quite selective. We can’t trust climate models at all — the climate is too complicated!! — but we can have 100% confidence in absurd economic models of GDP growth.


It is important to realize that virtually all experts in the area ARE convinced by the data that humans are ~100% responsible for modern warming. So you can believe Koonin or you can believe the 99.9% of scientists.


Koonin’s arguments are 1) cherry picking of factoids and 2) value judgements about his interpretation of the data and his interpretation of risk. His judgements of the data disagree with virtually all expert scientific opinion. His risk assessment is based on his values.


I typically don’t believe in conspiracy theories, but the fact that Steve Koonin continues to get high-profiles endorsements of his dumb arguments suggests that some powerful media agents have decided that he’s their best bet for trying to cast doubt on climate science. Thoughts?

Dessler likes to use other words against Koonin’s views such as “idiotic complaint” and “denier shuffle.”

Andrew Dessler pretty much embarrasses himself, his department, and his university with such vitriol. Why?

Part of it is Dessler’s certainty that the science has reached certainty on what is known and not known. No shades of grey on the very pessimistic, alarmist black-and-white conclusion: humankind is on the road to doom.

So hyper-emotionally invested. Anything less than alarm–even by a scientist every bit as credentialed as himself–and Dessler must turn emotional and angry.

Second is old-fashioned envy. Koonin’s Unsettled — with sales exceeding 100,000–has outsold all of Dessler’s books put together. Koonin, moreover, has a reputation that Dessler does not. And Koonin is a go-to for a lot of organizations that are trying to cut through a lot of politicized science.

Little wonder that Andrew Dessler will not dare debate Koonin at Texas A&M. (I have offered to underwrite such a campus-wide event to no avail.) The climate alarmist, arguing a speculative position, cannot get away with a lot with the bright lights on. [1]

Appendix: Wrong Again?

Regarding Koonin’s major points against settled, alarmist climate science, Dessler states:

I don’t see that these are the kinds of arguments that get traction with the broad public anymore…. Most people, they look out their window and they can see climate change is real. Given the fact that what’s happening is exactly what was predicted by scientists decades ago. I think that people understand that climate science is real, as described by the scientific community.

Really? Is this a ‘settled’ fact, Professor Dessler?

Actually, it is panic time for climate alarmism among the political and intellectual elite. Citizens are protesting, and voters are voting against the forced energy transformation, itself the flip side of climate exaggeration.

Better yet, with the problems of wind/solar out in the open (and at an early stage of the transition!), the open-minded are looking anew at the science and false climate prognostications of years and decades past. They are not very impressed. Expect sales of Koonin’s Unsettled to grow and another edition to appear in the next years.


[1] My email exchange with Professor Dessler (11/09/2021) follows. I stated:

Let’s have a debate between you and Steven Koonin or even David Friedman with a full house at Texas A&M to put you on record–will you consider that?  I’ll make a $5,000 contribution to the university to help make it happen. Put the bright lights on where the statements will be on the record. Televise it. But it has to have a fair moderator and set-up.

He answered that day:

Add a zero ($50,000, donated to the Texas Center for Climate Studies at Texas A&M) and you have a deal.  You can even moderate the event and handle all of the logistics. I’ll find a room on campus.

I answered (11/14/2021):

No thanks for the invitation to increase my contribution from $5,000 to $50,000. And for me to moderate, etc. I want a real debate with me in the audience or watching it on TV. It deserves prime time with physical climate science on trial.

No reason to relegate a climate discussion/debate to the ‘back of the bus,’ right? That is an insult to you, your opponent, and science itself.

So work on a serious budget, and let’s give it the attention it deserves. I will increase my donation appropriately….

A fair debate between the alarmists and the optimists is prime-time important. Why have it in some basement? Let’s put the lights on and have a marque event….

Professor Dessler did not respond….

This is the myth of Higher Education.

We believe the universities and collages are vast pools of global knowledge and we should be grateful they are willing to share with us small stupid people.

Yet who is telling us they are vast pools of knowledge? Well… they are actually.

They have become a vast circular reference. They tell us how good they are because only they are qualified enough to pass that sort of judgement.

In pragmatic terms the main role of higher education these days is to keep the unemployable out of the job market.

I stopped watching when Dessler tried to blame thermal expansion failures on Global Warming. He’s a prof. at a highly regarded engineering university. How could he be so ignorant? Is there not a single professor, grad student of even an engineering underclassman who will take Dessler aside and explain to him that design of thermal expansion joints is based on standards and principles that have no relationship to an insignificant change in global average air temperature? The Dean of the Texas A&M Engineering school should issue a public reprimand of Dessler and demand that he set the record straight. His interview with Rogan brings the reputation of a once great institution into question.

For the non-engineers out there, thermal expansion joint design is based on a material’s dimensions, thermal expansion coefficient (change in length per degree change in temperature of the material per length unit, usually in parts per million). The temperature used in the design calculations is based on the extremes known to occur plus a safety factor. The safety factor is always much larger than could conceivably occur in reality. Joint design parameters include both minimum and maximum temperature analysis. There are of course still failures in the real world due to thermal expansion. but they are usually the result of improper construction, deterioration due to age or lack of maintenance.

BTW, thermal expansion failures such as highway pavement buckling, rail road track bending and bridge issues are driven primarily by very high temperatures from direct solar heating. Think “fry an egg on the sidewalk”.

February 18, 2022 8:19 am

Including the fact that the temperature variations that occur every single day for which thermal expansion joints are designed (not to mention those throughout the year) wildly exceed any climate-driven changes expected by even the worst alarmists.

I stopped at the same point. 40mins of ad hominem attacks on Koonin and incredibly missleading statements on things like renewable energy. Then he started claiming localised weather events and yes the failed thermal expansion joint as evidence of global climate change that anyone can see. This is in direct opposition of what all experts say can be done. Weather is not climate. It was like watching a used car salesman work on an elderly lady. I saw no discussion of actual science at all.

He did admit that koonin’s facts were accurate and both climate models and economic models are unreliable though because they are so reliant on the human inputs that create them.

This is the same Dessler who claimed in 2010 to prove observational positive cloud feedback (as modeled) using clear sky/all sky satellite observations. NASA‘s website gave it prime time at the time. Only problem was, Dessler’s paper posted a figure of his data and regression result. His positive correlation had an r^2 of 0.02–essentially zero. And he was too ignorant of basic statistics to realize it. Steve McIntyre hilariously posted on the goof at the time. It appears that he has not learned much since then. Much the same as Mann and many others of the ‘settled science’ ilk.

They all now have a very basic problem. Their predictions are now provably untrue after almost 40 years:
Sea level rise is not accelerating.
Arctic summer sea ice has not disappeared.
Modeled warming has not materialized.
CMIP6 ECS estimates diverge further from observational estimates, rather than converge.
It is a long list. Children still know snow. Polar bears thriving. Crop yields up thanks to greening. Pacific Islands net gaining surface area. Their favorite ruinable solutions are, in fact, ruining electricity cost and grid stability in CA, UK, and Germany. COP26 failed. China and India won’t play.

So of course Dessler won’t debate. If he does, he is toast.

  • The same “greenhouse gas” that couldn’t stop the occurrence of a full blown glaciation at 4,000ppm will now cause a runaway greenhouse effect at 1/10th that amount.

One huge problem is that there is such a vast gulf between what “scientists” know and what journalists write in the media about what they think they heard when they interviewed the scientists. I have many times read the science paper that is the basis of a magazine article, and wondered how the journalist ever came to the conclusion that ended up being published in the media….once in a while the total opposite of what the scientist actually reported.

Add to that scientists who are so invested in their predictions of future disaster as a vocational enhancement for their publish or perish career.
Both Koonin and Dessler probably agree that there has been a degree of warming since the Little Ice Age, and they likely agree on how much IR will be absorbed in 2 meter long tube of CO2 in a laboratory. Those can be shown by scientific investigation. But Koonin and Dessler have very different views about whether CO2 is a problem in Earth’s atmosphere by 2100 or not. I wouldn’t hold out much hope for them being civil with each other in that debate.

And they are both smart enough to get a Ph.D. but can’t actually tell us the answer, because they don’t know.

Scientists are more often wrong than right. If that were not the case there would be no need for experiments and we could go straight from hypothesis to theory, skipping out all those inconvenient bits of the scientific method.

Prof Dessler is too arrogant to admit that climate science, from both sides of the debate, is mostly wrong and climate prediction is nothing more than guesswork (hypothesis) which has time and again over the last 50 years proven to be a fools errand.

Dessler has agreed to debate Alex Epstein. And he did debate Richard Lindzen at UVA Law school years ago. Link below.

During a hot and dry spell in 2011, Dessler predicted that Texas would be hot and dry for the rest of century. That prediction has not aged well.

It became settled exactly on January 20th, 1993. That’s when Bill Clinton was sworn in as US President and Al Gore was sworn in as US vice President. They turned on the NSF money spigots to those who proclaimed climate change gospel, and turned off the grants to folks like Bill Gray who they deemed deniers.

No more real debate was allowed from that point forward. #43Bush Jr was just a speed bump for them, slowing down their effort, but too steeped in the Swamp to care. Al Gore of course never recovered his political footing.

I listened to both episodes. I thought Koonin’s delivery was terrible, but spot on with the facts. Dressier was just awful – awful in so many creepy ways.

He spent basically the entire show making backhanded comparisons of Koonin to lawyers representing tobacco companies. Very creepy. What’s even worse is you could tell this was his strategy going in. It was a theme he repeated endlessly.

His arguments that wind and solar are cheaper than fossil fuels beggars believe. It takes about five minutes of research to destroy that story. And his argument that 100% of increased temps is caused by CO2 was ridiculous. Anyone who knows temps dropped from 1940 to 1980 can obliterate that so-called argument. Unfortunately, most people don’t know this.

His refusal to debate the science of climate change backfired big time. Joe is always respectful and pleasant with his guests, but you could clearly see he was not impressed with Dressler. Rogan pressed him on the issue with multiple questions.

When someone tells you the Science Is Settled, you nicely tell them:

“I have been hearing that the ‘science is settled’ for the last 15 years. I didn’t really give the statement much thought, I just figured that saying ‘the science is settled’ was just a weaselly way to get out of true discussion or true debate. So, I guess I was wrong … tell me then, just exactly when, what year, did the science become settled?”

follow up: “Well, since there really isn’t a month or year when it became officially or unofficially settled, what was the main event, idea, or proof that produced the settlement agreement across the board?”

follow up: “I do realize that it would be tough for you to answer for others, but it seems that you would have at least discussed with others in your field, and you would have an idea. At least, maybe, you can tell me what year and month it became settled for you personally; and what was the final impetus for you, as a climate scientist? (wait … wait … before you answer, take a little time to think about your income string over the last 25 years)”

I don’t know much about Mr. Dessler, but I emailed him today saying that “no science is settled”, “no real scientist would ever say so”, and “you are a fraud”. He replied with this question: “You don’t think it’s settled science that cigarette smoking causes cancer?”. I replied with many comments, including “no, the science of cigarette smoking and its effects on human isn’t settled yet”. I’m waiting for his reply and encouraged him to reconsider his debate rejection with Rogan. I was surprised that he replied with such a poor analogy to climate science.

Mr. Dressler,

“I don’t think the smoking of one cigarette causes cancer. There are lots of regular smokers that died in their 90’s from other causes … no cancer. Simple logic … smoking alone does not cause cancer. Not to say that smoking cannot cause cancer.

Smoking can trigger cancer. More smoking is more likely to trigger cancer … sure most agree that this is settled.

But the science of cigarette smoking/smoke, and its effects on human health, and cancer, isn’t settled.

Can you elaborate a little with your comparison/analogy please? I don’t understand how your question about the relationship of smoking to cancer has anything to do with our lack of understanding how the earths climates behave (eg. how clouds & water vapor moderate potential changes … I believe you are an expert on the subject and you were still dead wrong.)”

Follow-up: Dr. Dessler did reply. And, his email was reasonable, well-thought-out, and made for a pleasant email conversation. Capturing the gist of his response, I found two main points: 1) He doesn’t enjoy debating, and 2) He recognizes that there definitely still exists uncertainty in the understanding of the science of climate and smoking, but thinks that the uncertainty in both are small enough to take action. Example: Banning the sale of cigarettes to minors. He believes that the debates about the uncertainty are debates about policy; whether or not to take action on the science. I disagree. Regardless, he expressed his views succinctly and politely in his email to me. I wish he would do the same in public – it would be of value to everyone.

Well this is not a mater of believes, but facts and one fact is that Willie Soon for example has a peer reviewed paper disagreeing with him on that particular point, so until Soon´s paper is falsified, Dessler is just wrong on this point.
Not to forget, that McKitriick had a very critical paper out in 2021 also falsifying the “science is settled” meme.
It is a fact that CO2-feedback only exists in models and those models are not verified and tobacco studies have nothing in common, that discussion only serves as a distraction. We should only get back to it once the climate problems are all solved.

“He believes that the debates about the uncertainty are debates about policy; whether or not to take action on the science.”

and as such, debates about Policy are reasonably characterized as debates about uncertainties & the associated ignorance. The Uncertainty needs to be defined prior to follow-up discussion, let alone adoption, of Policy.

Mr. Dessler 🙂 wants to adopt policy without providing a clear picture of the associated Uncertainty. Cart before the horse type thing … his argument that we got to get there in a hurry, so how we hook up the horse doesn’t really matter is crap.

February 17, 2022 7:01 pm

So a few points:

1) He talks a lot about wind and solar and agrees they are not continuous power sources, but that we don’t need a large storage systems or grid wide battery systems because we can just have “dispatchable” power (nuclear /gas etc) ready to fill the gaps, but this only needs to be at around 25% of baseload grid requirements.

How does that work in a situation where wind and solar fail? Which will happen. How will 25% cut the mustard?

2) He also talks about “shifting” the load. So for example if peak generating power with renewables occurs mid-afternoon, but peak load occurs in the evening (when there is no sun), somehow we can “shift” the power generated in the afternoon to the evening. How does that work unless you have grid capacity storage system?

3) He somehow tries to justify “climate models” by saying “economic models” don’t work (he lost me there). Having said that, I am, pretty sure Koonin used economic modelling based on the IPCC data, and even that was pretty conservative (I could be wrong on that)

4) He admits he does not know a lot about battery technologies (when he was pushed on it) but admits we don’t currently have the resources in the ground to go full electric, but that does not matter, we will work it out.

No wonder he won’t debate, too much Magic Bean Stuff going on in his head.

Poor old Joe R, the price you pay trying to keep the lefties onboard.

February 17, 2022 7:24 pm

Dressler says he won’t argue the science, the science is set. What an utter coward. If the science is set and Dressler supports the science then he should be chomping at the bit to debate Koonin. If Dressler were correct then he could rake Koonin over the coals and make a fool of him. Why would he pass up an opportunity like that? I can tell you why, it is because the science isn’t set and I would bet money Koonin would take Dressler to the cleaners and all of the other lazy inept climate scientists with him.

Dressler thinks CO2 gas can be safely sequestered in deep wells, but fracking water cannot.

Dressler thinks CO2 is 100% responsible for warming, but the IPCC AR5 says CO2 was not high enough to affect the climate until about 1950 … yet sea level rise is recorded back to 1850. Apparently the future controls the past.

Dressler harped over and over that Koonin is a ‘merchant of doubt.’ Yet Dressler was the author of ad hominin attacks, and refused to debate.

>> anyone arguing that the science is too uncertain
>> virtually all experts in the area ARE convinced
and many more arguments like that should consider
– that the biggest change for the latest CMIP 6 model generation was the improved
simulation of local clouds.

This massively impacted the simulated CO2-feedback.
I believe this is an undisputed fact.
It does not mean that CMIP6 models have proven to be a reliable representation of the real world, however, it does show that all older models are missing something relevant.
Which means that those 99.9% cited scientists drew conclusions using an incomplete picture, which is very unscientific and should be rightfully criticized.

Not to mention a still missing rebuttal of McKitrick´s critique on attribution, after all he has shown nothing less than the current process is mathematically wrong.
This affects millions of papers and articles over the last 23 years and I think it should be put on any sceptical webpage with a counter.. so far about 6months have passed since Ross invalidated attribution from model results to the real world.

These two easy facts alone put the climate science in a very bad place and this argument from authority Dessler is trying to make here seems just hot air and very unconvincing.
He was given a chance to present facts, but choose not to do so.

It would be like a prosecutor telling a jury that they all claim that the evidence is circumstantial, like Ted Bundy’s lawyers did, so it mustn’t be true.

Every scientist, before their work was debunked or accepted, has had to deal with criticisms that there was too much uncertainty for it to be convincing. Deal with it like all the good ones did as well as the tobacco companies.
