Joe Rogan, Jordan Peterson Slam Climate Predictions

Guest essay by Eric Worrall

Climate Blasphemy! Jordan Peterson, whose podcasts have had over 285 million views, and famous Actor / Comedian Joe Rogan who hosts the wildly popular Joe Rogan Experience, have triggered the entire alarmist community by explaining why they think climate predictions are unreliable.

Their broadcast got so much attention, singer Neil Young is boycotting world leading podcast host Spotify for carrying such material.

Jordan Peterson and Joe Rogan Talking About Climate Change Will Make Your Brain Dissolve

The big boys had a big thinky about climate change.

By Molly TaftYesterday 1:20PM

Rogan and Peterson waxed on about climate for a good 30 minutes at the beginning of the four-hour-plus (!) episode of the Joe Rogan Experience, which was released Tuesday. I listened to the whole thing and it made me want to self-immolate. I’ll spare you all the bulk of the exchange because I would like you to continue to exist in a less flammable state, but I feel obligated to share the stupidest parts here, so you can share in my pain.

PETERSON: Well, that’s ‘cause there’s no such thing as climate. Right? “Climate” and “everything” are the same word, and that’s what bothers me about the climate change types. It’s like, this is something that bothers me about it, technically. It’s like, climate is about everything. Okay. But your models aren’t based on everything. Your models are based on a set number of variables. So that means you’ve reduced the variables, which are everything, to that set. Well how did you decide which set of variables to include in the equation, if it’s about everything? That’s not just a criticism, that’s like, if it’s about everything, your models aren’t right. Because your models do not and cannot model everything.

ROGAN: What do you mean by everything?

PETERSON: That’s what people who talk about the climate apocalypse claim, in some sense. We have to change everything! It’s like, everything, eh? The same with the word environment. That word means so much that it doesn’t mean anything. … What’s the difference between the environment and everything? There’s no difference.

‘Word salad of nonsense’: scientists denounce Jordan Peterson’s comments on climate models

Speaking on Joe Rogan’s podcast, Peterson claimed the climate was too complex to be modelled accurately, which was quickly shot down by scientists

Graham Readfearn

Leading climate scientists have ridiculed and criticised comments made by controversial Canadian psychologist and author Jordan Peterson during an interview on Joe Rogan’s podcast.

During a new four-hour interview on Spotify’s most popular podcast, Peterson – who is not an expert on climate change – claimed that models used to forecast the future state of the climate couldn’t be relied on.

Peterson told Rogan that because the climate was so complex, it couldn’t be accurately modelled.

He said: “Another problem that bedevils climate modelling, too, which is that as you stretch out the models across time, the errors increase radically. And so maybe you can predict out a week or three weeks or a month or a year, but the farther out you predict, the more your model is in error.

“And that’s a huge problem when you’re trying to model over 100 years because the errors compound just like interest.

Peterson said that if the climate was “about everything” then “your models aren’t right” because they couldn’t include everything.

Prof Michael Mann, an atmospheric scientist at Penn State University, said Peterson’s comments – and Rogan’s facilitation of them – was an “almost comedic type of nihilism” that would be funny if it wasn’t so dangerous.

Peterson’s claim that the climate was too complicated showed “a total lack of understanding of how science works” and could be used to dismiss physics, chemistry, biology, “and every other field of science where one formulates conceptual models”, according to Mann.

“Every great discovery in science – including the physics that allowed Peterson and Rogan to record and broadcast their ridiculous conversation – has arisen through that process,” he said.

Gavin Schmidt freaking out;

What is upsetting the climate community is between them Joe Rogan and Jordan Peterson command a gigantic listening audience.

I haven’t listened to the full podcast, but it dives into climate prediction, EV problems and renewable energy vs nuclear right from the start, so it has me hooked.

“why are the left wing types in particular so willing to sacrifice the poor”?

The climate community overreaction may end up being more damaging to the cause of climate alarmism than the original podcast.

All those publicity hungry Youtube and TikTok personalities out there right now who are watching and taking notes have just learned, if you want a gigantic deluge of free publicity from a wide range of outraged liberal media outlets, all you need to do is shoot a few sacred climate cows.

Update (EW): Cancel campaign on – Newly appointed Biden Surgeon General Vivek Murthy in my opinion has come close to asking Silicon Valley to censor Joe Rogan – he stated that silicon valley has “an important role to play” suppressing the spread of Covid misinformation, in an interview which mentions Joe Rogan.

Peterson told Rogan that because the climate was so complex, it couldn’t be accurately modelled.

Even the IPCC knows that:

In sum, a strategy must recognize what is possible. In climate research and modeling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that the long term prediction of future climate states is not possible.

The global climate is an Icehouse Global Climate.
Predictions are our Icehouse Global Climate is easy:
We are in an Ice Age and we will stay in an Ice Age.
We say things about our 34-million-year-old Ice Age.
First, it’s got a name: The Late Cenozoic Ice Age or
also called, Antarctic Glaciation.
And everyone agrees we in the coldest period [in last couple millions]
of this Ice Age. And our last glaciation period might be the coldest and
that your interglacial will end, and we again enter another glaciation period.
But there is no agreement about when this will occur, nor is there any agreement
what counts as the beginning of a glaciation period. Or persons in 1970’s were
claiming we were in the beginning of a glaciation period. Or the ice age is coming!!
But informally speaking a glaciation period is also called an Ice Age. But can’t really enter
an Ice Age, because are still in one. But we can certainly enter a glaciation period, and possible we have already entered one. We have long past our Holocene thermal maximum,
but one could imagine that unlike the other interglacial periods, we could have double peak temperature within our Holocene interglacial period. Or there are some ideas that human activity will significantly lengthen our interglacial period- some have claim for as much as for 75,000 years- which about as crazy as it gets. No one believes we are going leave our Ice Age.
Our ocean is still cold.
Our ocean has been about 2 to 4 C for last couple million years, and for most the last 34 million years, there was many times our ocean got warmer than 5 C.
And at moment is about 3.5 C.
And has been around this temperature for thousands of years, and likely stay around temperature for another thousand years.
If ocean our were to get to about 4 C, I think we get another green Sahara desert like did during Holocene Climate optimum. This commonly referred to as the end of world, ie, CAGW.

And if gets to about 3 C, that pretty firm evidence we are going pretty fast towards a glaciation period.
Though another way to say it, is that most of last couple million years has had an ocean which is about 3 C and most of 2 million years has not been comprised of interglacial periods.
Another way of saying it, is that 15 C is cold air, but we had colder air in the past.

But the good news is that about 40% of earth surface is the tropical zone, and tropical zone stays about the same temperature whether in deepest part of glaciation period or warmest
part of interglacial period.
Or tropical island paradises are for “forever”- unless they get hit with a space rock.

The current cycle of glaciation commenced 400 years ago. That is the last time perihelion preceded the austral summer solstice. Since then boreal summers are getting more sunlight and boreal winters less sunlight.

So far the changes are less than 1w/sq.m over any month but eventually the sunlight in June over the NH will average 21W/sq.m more than present.

The lower sunlight during the boreal winter mean more moist air convergence from ocean to land with increasing boreal winter precipitation – a good proportion falling as snow. It will begin accumulating in the coming millennium.

This is real climate change based on orbital mechanics that no amount of CO2 can alter.

As the ice mountains form, the average surface temperature of earth will decline because the elevation of the ice on the land will increase by hundreds of metres. Think of Greenland like conditions across northern Europe and Canada.

Thanks, Coeur de Lion, for the reminder of Donna Laframboise’s work. In order to fully expose the corruption, it also needs to be proven that there has been no demonstrable justification for declaring a climate change emergency. In Canada, so many of our universities have signed on to this declaration. Wasn’t deception used as a rationale for wasting money on mitigation efforts like industrial scale wind turbines? Is this not racketeering?
Jordan Peterson and Joe Rogan have brought this crucially important conversation into the public arena.

To overuse the Emperor’s New Clothes theme, pointing out that the moles on Mann’s or Schmidt’s butts might be a melanoma is precisely what Peterson was doing.
The grids on computer models are too coarse to model clouds, let alone thunderstorms, so Peterson is quite on point.

Mann avoided being cross-examined because of his inexcusable delays, in his lawsuit against Tim Ball. Thus he didn’t produce evidence under his control. Because of adverse inference, he demonstrated that he does indeed belong in the state pen. The Mann’s an admitted fraud.

Rogan would tear Mann to shreds and Mann knows it. Apparently his stupidity and over-confidence actually do have limits.

It is amazing how the Left always falls back on obfuscation and rhetoric:

I have an Excel spreadsheet I programmed. When you input 2 + 2 the output is always 5. I have tried it a thousand times and it “works”, the output is always 5.

And that is how the climate models “work”. And it is off limits to question the programming on the input side and when the output side does not match reality, that is when they get to work on reality, by adjusting the data and if necessary the theory.

Mann & Schmidt are correct, the models “work” perfectly, the same way my Excel spreadsheet “works”. And they use that assertion for the “other work” people really want to know the answer to: do the climate models accurately reflect and predict reality?

They use the same dodge to answer questions like: “Is the climate warming?” Answer: “97% of scientists say yes.” However that is an answer to a question that was not asked. If you ask about a murder: “Did John kill Joe?” The answer: “The jury said he did” is an answer to a question that was not asked. However, both of those “answers” fill in a space and usually suffice to throw people off the track and stop the questioning.

And that sleight of hand epitomizes the Left: We believe in science & democracy, just not the outcomes. (sigh)

“Every great discovery in science – including the physics that allowed Peterson and Rogan to record and broadcast their ridiculous conversation – has arisen through that process,” he said.

Oh I do wish our dear Monckton could get hold of that one. It’s just so darn illogical.

The fact that we’ve made great strides with mathematical simplifications of reality does not prove that all problems are amenable to that approach.

Lorenz demonstrated that the climate can’t be modeled. link Rather than finding a way around the problem, and demonstrating its validity, folks just ignore it.

Lorenz never demonstrated that climate cannot be modelled. What he showed was that in a particular simplification of the atmosphere (3 nonlinear coupled ordinary differential equations) then trajectories have a sensitive dependence on initial conditions. However that is very different from saying that the climate cannot be modeled. Nobody would doubt a statement that in 1000 years time winter will be colder than summer whereas anyone who claimed to be able to predict when it will snow next year is lying.

Lorenz showed that trajectories converge onto a strange attractor. And if you like you can think of the climate as being the strange attractor and the weather as being where on that you are. It is possible to map out the strange attractor and how it would change as the parameters in the model change without being able to accurately model any individual trajectory.

Incidently the link you gave has not aged well. The last paragraph states:
”The prospect of the current hiatus lasting until the mid 2030’s (as per the stadium wave and related theories of natural variability) is a decisive test for IPCC’s AGW detection arguments. Detection of AGW is a prerequisite for the IPCC’s attribution arguments. The IPCC’s statements of 95% confidence that most of the warming is anthropogenic, and expectations of substantial warming between now and 2036, has the IPCC skating on very thin ice, in my opinion.”
which was published in 2013. Since then the earth has warmed by about 0.2 degrees according to satellite measurements suggesting the stadium wave theory has been proven wrong.

Reply to  Izaak Walton
January 27, 2022 7:37 pm

Wow, 9 years proves the stadium wave theory wrong, but it takes 15 years of no warming to prove the CO2 thermostat theory wrong. Until 18 years of no warming occurred, then we just forgot about that.

In 2013 Prof. Curry predicted on the basis of the stadium wave theory that the then current hiatus would last until the mid 2030’s. In the 9 years that followed the earth has warmed and in fact the warmest year on record was during that period. So that is long enough to show that Prof. Curry’s prediction was wrong.

January 27, 2022 10:14 pm

What Lorenz showed was that there was a strange attractor in the system to which all trajectories converge. That attractor is what makes modelling the climate possible. You can think of the strange attractor as the climate with well defined properties. The weather corresponds to the particular point on the trajectory — that is what is impossible to predict. But there are a lots of properties of the attractor that are well known such as the maximum or minimum points on it. You can also predict how the attractor changes shape as the parameters change — this is the equivalent of climate modelling and can be done without knowing what any individual trajectory will do.

Reply to  Izaak Walton
January 27, 2022 10:55 pm

Pure BS, Isick. If the strange attractor caused all trajectories to converge, you wouldn’t see the HUGE variability in future climate trajectories between models and the very large variability in individual model runs assuming that all the models have the physical processes correctly modeled. But there IS a huge variability.

You’re lying, Isick. Again. The sad thing is you thought you could BS people with common sense, let alone people like me who have physics and math degrees who understand that any strange attractor is unique to the problem being solved. If the model gets the physical description wrong you get the wrong answer whether or not that particular set of equations has a strange attractor.

You truly are a clown, Isick.

Izaak the Liar said, “What he showed was that in a particular simplification of the atmosphere (3 nonlinear coupled ordinary differential equations) then trajectories have a sensitive dependence on initial conditions. However that is very different from saying that the climate cannot be modeled”.

Inadvertently, Izaak is partially telling the truth here. A the number of iterations increases, so does the sensitivity to initial conditions. IOW, after a certain point, the slightest difference in initial conditions results in gross differences in outcomes, and this sensitivity increases exponentially with time. Pat Frank has demonstrated this quite conclusively.

How would the attractor be the climate if that’s what is being modeled? Wouldn’t the attractor be the point of stability?

How about this: two attractors, two points of stability: Glacial and interglacial.

The Earth’s orbit changes over long times leading to periodic climate changes including the timing of glaciations. Look up “Milankovitch Cycles”. These orbital changes causes fundamental changes in the amount of Solar insolation, the length of seasons, and where the sun’s energy gets absorbed on the planet. This is not the result of two attractors in the same equations, it’s completely different boundary conditions at different times.

Two very trivial tests for climate models that demonstrate they are useless:

  1. Subtracting the mean model output (CMIP5 or CMIP6) from the individual model runs leaves uncorrelated random noise for the residuals. Because the mean model output can be derived trivially from linear regression of the input forcings this demonstrates that climate models add nothing to our understanding of climate
  2. Latest CMIP6 models have (a) 4x the variance observed in the temperature observations and (b) a bunch of them run so hot that even Gavin Schmidt and the IPCC AR6 report had to cull them from the short term warming projections

Bottom line is climate model output is just a nonsense model driven by putative forcings. Climate model output is nothing more than linear transforms of the input forcings in W/m^2 to temperature in degK. And the models can’t even agree on the mean output temperature of the earth to better than a 3 degK range whilst claiming to model C20th increase amounting to less than 1 degK.

“Here, our focus is solely on complex climate models as predictive tools on decadal and longer timescales. We argue for a reassessment of the role of such models when used for this purpose……………..Complex climate models, as predictive tools for many variables and scales cannot be meaningfully calibrated because they are simulating a never before experienced state of the system…....It is therefore inappropriate to apply any of the currently available generic techniques which utilise observations to calibrate or weight models to produce forecast probabilities for the real world

I agree – climate models are unscientific nonsense. So is global warming alarmism (now re-labelled “climate change”) .
The Klimate-and-Kovid-Klowns (KKKs) predicted dangerous global warming and now it’s getting colder.
Conservatively, the odds of their predictive track record being this wrong are much worse than 1 in 281 trillion.
100% lies from the KKKs for ~five decades. No rational person or group could be this wrong for this long – they know they’ve been lying since Day 1.

Pardon any typos as I dictated this note.

Thank you Leo. I have some concerns about your comment regarding chaotic systems that can “orbit for a while before careering off in an entirely new direction”. I had a conversation on a similar topic with my friend Will Happer a few months ago and I pointed out that I accurately predicted the current global cooling 20 years ago in 2002 and more precisely (within less than one year) in 2013. I also cite Willis Eschenbach’s recent paper in which he discusses the incredible stability of global average temperature over many years. It seems to me that your statement about the unpredictability of chaotic systems is directly contradicted by my accurate 20 year old correct predictions of global temperature – within a few tenths of a degree.

I concede your comment could be accurate at much longer time scales, because of the existence of continental glaciers.

For the record, I also predicted in 2002, and more precisely in 2013 the current cold-weather-and- green-energy crisis in Britain and Germany that is happening now, based on solar cycles.

It is true that the warmists’ climate models are abysmally inaccurate in their predictive ability. The mainstream skeptics’ argument is that the model inputs assume that climate sensitivity to CO2 is ~3 to 5 times too high. I published in 2008 that in reality the climate models are a scientific fiction, because I proved then and Kuo et all published in ~1990 that atmospheric CO2 changes lag atmospheric temperature changes in the modern data record, and we also know that atm. CO2 changes lag atm. temperature changes by a much longer time in a much longer cycle period in the ice core record, so the climate models have the causative relationship backwards, a.k.a. “the cart before the horse” and “the future cannot cause the past”.

Both sides of the mainstream climate argument about the magnitude of climate sensitivity to increasing atm. CO2 are based on a scientific falsehood; nevertheless the climate skeptics are much more correct, in that their “upper bound’ (not their “best estimate”) of climate sensitivity to increasing atm. CO2 is only ~1K/(2XCO2) and there is NO real catastrophic human-made global warming crisis – it’s been a false crisis for about five decades – “wolves stampeding the sheep” for political and financial gain.

It was more a case of limitations of numerical analysis, and is quite an interesting field of computer science.
Sensitive dependence on initial conditions is an inherent feature of repeated iterations, where the output of an iteration is used as the input to the next. It is most pronounced near domain boundaries, such as turbulence in fluids.

Increased CPU power, more memory, larger floating point variable sizes and other advances since Lorenz’s time have pushed out the number of iterations before calculation “blow up”, but they tend to do so eventually.
One of the major benefits of knowing about the phenomenon is to realise the need to use multiple runs with different starting conditions to check the stability of the calculations.

Satellites do not actually measure temperature directly. All they can do is measure radiation at some point in space and then use a whole bunch of assumptions, correlations, calibrations, and algorithms to estimate temperature. All very admirable but It is far less precise than we have been led to believe. We don’t know what the instrument errors are, what the correlation coefficients are etc etc but I think a change of 0.2 deg is less than their order of accuracy. Then the question also still remains: they are measuring the temperature of what precisely?

That the problem with all temperature measurement the variables will get you ever time. If you do everything right over and over you might have an error of less than .5 F. Adding up a bunch of measurements of varying errors does not then dividing them out does nothing to improve precision. “Correcting” the data does noting to eliminate the errors since you have no idea what the errors are, you only have you assumption what they are. I not a “train scientist”

I am only a technician yet I spent a life time making measurements on acting on them, more often than not the measurements and equipment is close to reality but most of time there are errors enough to mislead you.

I learn early on if you measured a precision voltage with a number of freshly calibrated precision instruments you got sightly different readings yet each meter was correct with in it error bars, adding up all the reading and dividing them out still will not tell you the correct voltage only a approximation of the voltage which most of the time that good enough.

But if you did that day in and day out you still cannot clam what the voltage would be within a few thousands of a volt. Yet they do that with temperature where the temperature is changing moment by moment.

I’ll be honest, I am less concerned with satellite than with surface measurements being used to find averages. Do satellites give an accurate depiction of surface temps? Probably not and they are not designed to. Do they give a more consistent interpretation of the temperature of the entire atmosphere it examines? I think it does. Why? Because they use a only a few measuring devices so that the compounded uncertainties are few.

Does the difference between a single point thermometer and sections of the atmosphere bother me? No, The consistency far outweighs far flung thermometers. What does bother me is the folks trying to compare UAH to surface measurements from the past. You just can’t do that.

Anything that can be perceived can be “modeled”…F = ma…but the efficacy of the model (in this case the ability to predict the future) is entirely contingent on the modeler’s grasp of what is and is not significant for the task at hand. So, if we live in a superdeterministic universe you only have to know everything-now in order for you to how everything will unfold (assuming your model is powerful enough to deal with everything-now and process it faster than reality is unfolding…) so the podcasters are only stating the obvious…the future is a mystery (due to ignorance of initial conditions) if on the other hand we don’t live in a superdeterministic universe then accurate predictions about the distant future become problematic….perhaps the models are telling us we DO live in a non-superdeterministic universe??? If so, the outcome is exactly the same…accurate predictions about the distant future become problematic.

Lorenz never demonstrated that climate cannot be modelled. What he showed was that in a particular simplification of the atmosphere (3 nonlinear coupled ordinary differential equations) then trajectories have a sensitive dependence on initial conditions.”

And they can also run off the rails when numerically resolved. And, that is with only 3 equations. What if 5 or 10 need to be used?

You also need to explain why they are only run for a year and are then restarted with the output of the previous one. Off the rails maybe! If they were truly predictive you could run the models for 30, 50, 100 years and they would stay within the boundaries established by the REAL EARTH.

USA weather forecasters are currently arguing about atleast 2 models for the next 24 to 36hrs. There’s a 50:50 of a factor of 5x the snow fall in some areas. One model predicts slow, hugs the coast & drops a lot of snow. Another predicts fast moving, away from the coast (more out to sea) and results in a few inch of snow at worst.
They make estimates of more or less if they can average over a long period of time but any deviation can be blamed on weather. But some models predict high at the same time other models predict low based on the same science. While climate models can’t predict exact weather for every day they are supposed to predict a plausible average over longer periods. If the errors and weather variations are both random from means then the averages should cancel out the errors so they look more similar. With enough smoothing, any random sequence can be made plausible.

The climate models require a grid of cells, while there is mathematics between the cells, the physics within the cells are often simplified to complex equations without the smaller particle physics which real weather is based on. The models are not bad at predicting temperatures but there not good at predicting clouds, precipitation & wind. Yes they are based on some physics but they are still far from perfect. The grid cell size needs to be decreased but that requires more computing resources. There are still great uncertainties of many of the variables so everyone chooses different values & multiple runs trying to cover more possibilities. It looks more like picking winners based on expectations of what output looks plausible instead of being decided by science & reducing unknowns.

January 27, 2022 7:54 pm

Peterson is correct about the infernal climate models being ludicrous.

According to CMIP 6 models, the global temp anomaly should be 1.35C by now, while the December UAH 6.0 anomaly was 0.2C and will likely be -0.2C by March of this year.

Long term, CMIP 6 climate models predict 4.0C of global warming by 2100, while all empirical evidence show it’ll be closer to 1C, if not lower..

To get to 4C from the current global temperature anomaly of 0.2C world require a warming trend of 0.48C/decade from now until 2010, which is absurd given the current warming trend for the past 40 years has been about 0.14C/decade.

Moreover, it’s highly likely when both the Pacific and Atlantic reenter their respective 30-year ocean cool cycles in a few years, global temperatures will fall for 30 years, proving most of the warming we enjoyed from 1979 to the present was from AMO/PDO warm ocean cycles and other natural phenomena and not from CO2.

I hope that Dr. Roy Spencer will soon prepare an updated graph comparing UAH 6 observed global temperature anomalies from 1979~2022 to CMIP 6 model mean projections over the same time period..

It would be hilarious.

Well, while his wording seems a bit awkward to me and taken out of context probably might not withstand for scientific scrutiny, I think he is spot on!.

Z. Hausfather for example showed a graph in a twitter response, how good models would match temperature measurements and there are a few things to say to that
a) the disagreement between the models increases by about 0.1°C per decade (and thus the graph directly SUPPORTS! Peterson´s statement!)
b) No previous model generation models clouds as good as the current CMIP6 global climate models. As these newest models struggle with assumed high CO2-Feedbacks, it is very clear the parameters older models use are simply not a description of the Real world.
Just like Peterson said.
A model mimicking the global temperature without getting all important parameters (like clods) correct is very meaningless. Just like a 4year old scribbling lines that match the Real world data!
c) I believe Hausfather might have left a few models out not supporting his idea and some parameters in the models he shows are ridiculously unreal!

d) There is also the more fundamental criticism by McKitrick showing that the process of attribution -“transcribing a model into the real world” – has potentially been done incorrectly for more than 20 years.

>> Hausfather, I am sorry , but this is not honest, this is not science!

Not surprisingly Mann and Schmidt also commented, both of them have to clean their own house, before they can comment on science.
When will Mann find time to correct or withdraw his flawed paper from 1998?
Schmidt defended the use of the use of Cape Ghir series (see for exampel here as marocco SST) as pure proxy to create figure 1a in the last IPCC SPM. Looking at the data it is obvious that there either was no Middle age or Roman warm period or the proxy cannot be used as pure temperature proxy.
Both some very simple and clear examples, that these two people do not act as they understood science.

Mann shows “a total lack of knowledge of how science works.” First comes observations then comes an attempt to explain the physical basis of the observations and to model the physical processes. The models are compared to reality and are adjusted or dropped in light of faithfulness to reality. Neither Mann’s nor Schmidt’s models pass the reality test. Although the narcissist Mann probably never admit to his models’ failure (see McIntyre and McKendrick’s work), Gavin was eventually forced to admit the CliSciFi models don’t work.

Couple of points:-

First the Guardian and their little Mann friend are reacting to Rogan/Jordan. Reacting. Like the advice goes, “maintain the initiative. If you don’t know who has the initiative, it isn’t you”.


“Every great discovery in science – including the physics that allowed Peterson and Rogan to record and broadcast their ridiculous conversation – has arisen through that process,” he said.

Ummm… no.

Models are not results. Models may be used to assist in predictions so that practical test procedure can be put in place, but they are NOT THE END PRODUCT.

On the same topic, I do not believe that Jordan ever actually said there is not a place for models in science, but that he said the overall system of ‘climate’ is so complex and poorly understood that the CLIMATE MODELS would never work.

So Mann would be wrong twice in this example.

If they must be reinitialized each period, i.e., annual or decadal, then they are wrong.

Then I look at how the doomsayers say that anything that happens is the result of global warming, er I mean climate change, and wonder how a theory that allegedly is supported by absolutely anything that happens except real world observation can be correct. Then I look at Climategate and wonder how I can believe anyone who confesses to lying and bullying to hide contrary opinion from what seem to be pretty normal people.

Digital computers can never never ever model climate

By their very definition (digital) there always comes a point where a decision has to be made about the Least Significant Bit/digit

  • is it =1
  • is it =0

and it is there that The Programmer makes the decision.
Thus computer models can never be any more than Opinion.

Thus, contrary to popular opinion that ‘computers never get anything wrong‘ – by their very construction and operation, they are wrong 50% of the time.
And there is No Way of overcoming that.

January 28, 2022 12:34 am

Jordan Peterson and Joe Rogan have injected into the mainstream conscious the climate science model equivalent of the “emperors got no clothes”.

I suspect many everyday people with common sense (eg tradespeople) have already worked it out for themselves. But it doesn’t hurt to say it again to a new audience.

The left will hate it. But then the left hate Jordan Peterson already so no change to the status quo there.

Strongly recommend Jordan Peterson’s debate with Michael Shellenberger. And Shellenberger’s book Apocalypse Never.

As for models…

From NOAA… a 10-day—or longer—forecast is only right about half the time. Meteorologists use computer programs called weather models to make forecasts. Since we can’t collect data from the future, models have to use estimates and assumptions to predict future weather. The atmosphere is changing all the time, so those estimates are less reliable the further you get into the future.

…isn’t that what Dr Peterson said?

From the article: “Prof Michael Mann, an atmospheric scientist at Penn State University, said Peterson’s comments – and Rogan’s facilitation of them – was an “almost comedic type of nihilism” that would be funny if it wasn’t so dangerous.”

That’s ironic. Mann and his Human-caused Climate Change scam is what is dangerous to humanity. Mann’s climate change lies are one of the main reasons the Western World has gone crazy over CO2 and is in the process of destroying their economies trying to fix the Climate Change Lie Mann has perpetrated.

Mann is the dangerous one, not Rogan and Peterson. Rogan and Peterson speak the truth. Mann speaks climate change lies. Mann should be prosecuted for the climate change fraud he and his cronies have perpetrated on the world with their bogus climate change computer models.

The less inflammatory way to put this is that Mann has personal experience with models not matching reality, and is already infamous for a controversy concerning how to hide discrepancies in climate models from skeptics. In other words, he’s the worst person possible to respond to Peterson’s antics, and they don’t even realize it.

January 28, 2022 2:41 am

Hang on, we were promised “leading climate scientists” and we got quotes by Mann and Schmidt???
The quote by Mann is actually sad in a way. He’s obviously spent his whole life in science, but demonstrates that he doesn’t have the faintest clue as to how it works in practice. To confuse a typical scientific model with several known variables that can be independently tested for influence, which is what that vast bulk of physics, chemistry, biology deals with, with a hundred-plus variable and untestable scope like climate, is astonishingly depressing. It’s also clear, based on previous discovery after discovery, that there are many future unknown variables, as well as many that are currently unknown in importance. That’s what science is finding every day, and somebody should tell him. It’s embarrassing (for him) that a psychologist has more insight into the complexity and pitfalls of climate modelling than a so-called expert in the area. I can charitably attribute it to ideological posturing, where he cannot bear to admit Peterson has a point, but I suspect he is actually clueless about the fundamentals. Sometimes, experts are so narrowly focussed that they cannot, or refuse to, see a bigger picture that is obvious to an outsider. Nutritional science also suffers from the same problems of hundred-fold variable complexity and, like climate science, loves to zone in on a single variable to explain an observation.

Very good post!
I also had that thought, that classical sciences use experimental data to construct a model (to then make verifiable predictions).
Climate computer models make predictions, but good data is lacking (and the possibility of verfication is often questionable).

Earlier I compared modeled global temperature trends with the scribbles of 4 year olds.If you pick the right line from a couple thousand scribbles I bet it can look surprisingly like a real world trend.

People like Schmidt praise the CMIP6 generation models as being a significant progress in terms of cloud modeling. This means that older models lacking these details are very close to random scribbles missing key features of the real system (but are carefully tuned by climate scientists)
Mann´s claim that there could be any knowledge gained similar to classic science is just plain wrong.
I hope Peterson follows up as public as possible on those “critiques”!

OkY DOKY, so if buzzballs like Mikey Mann get their undies in a bunch because someone – some utterly terrible person (or persons) is questioning ITS authority (which does not exist), then here’s my prediction:

We will definitely have periods of climate changing from warm and wet to freezing, bitter cold with AND without wet stuff. (Deserts can be quite cold when the Sun’s gone down.) They will happen because the planet has its own agenda, and that’s the long and short of it. We will also have prolonged periods of cold called WINTER and prolonged periods of warm called SUMMER. (I prefer Spring through early Autumn, and Winter is not my favorite time of year, so I stock up and make popcorn and write ridiculous spooky fiction.) At some point in time, the snow line will start to creep further and further south, but we won’t live long enough to see it really happen. That means the glaciers and frozen seas will return, and a LOT of water will be locked up in glacial ice. That means that submerged land will reappear and migration routes of animals like moose and deer will very likely change, never mind the hunting trails of wolves, coyotes, grizzlies and polar bears. 🙂

That’s my story and I’m sticking to it. As much as I’d like to borrow The Doctor’s TARDIS and give those Bozos a REAL hint of what’s to come, I will continue to get photos of geese and ducks coming home from their southern visits and look for the wildflowers on the local trails, as well as a few fine fishing friends who are now out on the nearest frozen lakes in their fishing huts, catching trout and northern pike.

If it weren’t so obviously a threat to the ridiculous egos of people like Mann and his ilk, we’d be talking about ice boat speed racing on frozen lakes, and reading novels in comfy chairs near the fireplace.

It is worth repeating what I have already commented on this website: There is no such thing as climate, one absolute climate for our globe with variations over the course of years and a range of weather conditions. There are, however, at least 30 climate zones and sub-zones. Each is subject to variations, a considerable range of weather conditions and a complex interaction with what happens in other zones. In reality we have a mind boggling complexity here.

The English artist, Sir Joshua Reynolds, had an extraordinary insight into the importance of observation. The great English scientist, Michael Faraday, understood the need to test every scientific claim, every assertion, through performing experienments to test the veracity of these. The astute 20th century Hungarian Mathematician, George Polya, wrote “In theoretical matters, the best of ideas is hurt by uncritical acceptance and thrives on critical examination.” These three and many other giants of the past would have laughed at the arrogance and foolishness of today’s alarmists who claim to be “climate scientists.”

Watched the whole episode. A couple things stood out:

“Rogan and Peterson waxed on about climate for a good 30 minutes at the beginning of the four-hour-plus episode”

Didn’t happen. This wasn’t a scientific critique, but an informal, long-format conversation between two adults. Rogan is generally open to the Global Warming and Anthrocentric Climate Change narrative. Peterson pointed out several logical and practical flaws to most of the Global Warming arguments.

“Speaking on Joe Rogan’s podcast, Peterson claimed the climate was too complex to be modelled accurately”


“Peterson told Rogan that because the climate was so complex, it couldn’t be accurately modelled.”

Didn’t happen. Peterson didn’t say this, but did casually point out several reasons why climate models can’t or shouldn’t guide policy, and cannot predict outcomes based on policy decisions and human action. These are quite different things. It is interesting that both Mann’s comments and Schmidt’s tweet seemed based on the misinformed interpretation of Peterson’s remarks by the reporter.

Peterson’s claim that the climate was too complicated showed “a total lack of understanding of how science works” and could be used to dismiss physics, chemistry, biology, “and every other field of science where one formulates conceptual models”, according to Mann.

This is obviously wrong in its judgement of Peterson who has worked credibly in his own scientific field for at least as long as Mann in his. One difference might be that Peterson has shown his work, performed repeatable and ethical experimentation to document and defend his work, and will debate the issues concerning his work in appropriate forum — all things that Mann cannot do. In that sense, the danger Mann describes is quite real – to Mann — in that he cannot and has not engaged in scientific debate or defense of his work, ignores valid criticism, uses political, financial, legal, and social pressure to silence critics regardless of their credentials. Even in this case, from the other quoted remarks, Mann hasn’t listened to the podcast but engaged with the reporter and with the anti-Spotify/Rogan cancel movement that is currently going on, when it wan’t necessary for him to address the podcast at all.

Guys, for the love of everything holy, please, please, have somebody on who knows what the heck a climate model is!!!

Peterson talks about his own policy work on sustainablility with the U.N. and Canadian governments, and hints about the study he’d put into the subject. Schmidt’s comment is unfounded, as it seems evident that Peterson may demonstrably know better about the scientific use of mathematical modeling, and is at least as professionally qualified and experienced as many who Schmidt and Mann would claim were Climate Scientists if they were faking another consensus survey.

As others here have said, I too would welcome a debate between Schmidt and or Mann and Peterson. I’d also break practice (I’m not a Rogan fan) and listen to a Rogan podcast with either of them. My pre-post time bet would be that Rogan or Peterson would take either of the other two apart, but I am equally certain that Schmidt and Mann know this, too, and will never engage honestly with anyone.

Peterson works on the basis of classic logic and fallacy. I watched the first 30 minutes and my takeaway was:

(a) he was surprisingly angry and a little agitated, so the climate nonsense is emotionally important to him
(b) he emphasised a series of logical fallacies both with climate modelling and left wing views on Net Zero and its impact on the poor
(c) he has clearly taken on board a lot of the views of Michael Schellenbeger and his book Apocalypse Never. Not surprising since he interviewed him and Schellenberger’s arguments are very rational and well argued.

To me, Peterson’s remarks needn’t be taken as anttack on Schmidt or Mann, and hitting back at the strawman weakens the Global Warming cultists claims. These two charlatans risk further exposure by addressing Peterson’s casual opinion on the reporters’ terms. If they’re maneuvered into challenging Peterson or appearing on Rogan they will lose.

Any concept that could be called a model. An example would be how the force of gravity depends on the distance between objects. The concept was that the force would be spread over a greater surface area the further from the larger object the second object was. The area was a function of distance so gravity should be inversely proportional to r^2. That inspired the postulate that was tested and became an empirical law. It didn’t prove the reasoning for it was sound, let alone justify it being the impetus for spending trillions of dollars to decarbonise the economy so that albatross divorce rates will not rocket.

Having Mickey Mannish criticize one’s veiwpoint is like being knocked around by dandelion fluff. And as for Neil Young – he made some great music, then he rapidly became irrelevant and annoying.

Paul Penrose
January 28, 2022 9:55 am

All models are wrong; some are useful. The usefulness is based on the fidelity of the outputs in regard to how well they predict actual outcomes. And even in the case where models produce results that closely match the real world, they are tightly constrained to narrow specific cases and/or time-frames, outside of which they have no meaning. The real trick is knowing under what specific circumstances a model is valid so that you aren’t fooled by invalid results. And generally speaking, the more complex the model, the more narrow is its domain of validity. This is what people like Mann and Schmidt either don’t understand, or are intentionally misleading people about.

January 28, 2022 11:09 am

I seem to recall, when I was in elementary school, I bought a model car at a local hobby shop. It was all plastic, the wheels didn’t move, and it didn’t have an engine or electrical system. But it was fun to play with and it resembled the cars people drove around in. That’s my impression of climate models compared to actual climate.

“And that’s a huge problem when you’re trying to model over 100 years because the errors compound just like interest.””

Well, adjusting the temperature record so that the 1920 and 30th are cold just to better fit the models is NOT what I would call science. Much better would be to admit that the models are a rough tool to study climate and worthless to predict future climate.

Always a pleasure to hear from Michael Mann, who intentionally subverts science to advance his personal interests.

One of the most important parts of the Scientific Process is that a scientist must publish his supporting data, algorithms, assumptions, everything upon which his theory is built. In this way others can check the data, assumptions, algorithms etc and replicate the experiment. Michael Mann refuses to share his data.

Phil Jones infamously said in Climategate, “We have 25 or so years invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it.”

Science is a search for truth. The entire point of Science is to try to find something wrong to determine whether or not a scientific claim advances the search for truth or not.

Jordan Peterson may not be an expert in climate, but he is an expert in research, statistics, and modeling in the field of psychology. The same fundamental techniques apply to testing theories in psychology and climate change. He is correct about the propagation of errors over time, a fact that climate modelers hand wave away.

George Daddis
January 29, 2022 8:08 am

“…could be used to dismiss physics, chemistry, biology, “and every other field of science where one formulates conceptual models”…

Another unsupportable opinion by Michael Mann. In all the other disciplines he mentions, actions and “policy” are based on conclusions from observed data, and not “conceptual” model projections. (You can “model” aeronautics, but they still use a wind tunnel before attempting flight.)

A scientist’s idea of what will happen if we fire a projectile into the sky is a lot more accurate than a projection from a “conceptual” climate model because the results from those calculations were repeatedly confirmed.

It’s critical to remember that climate modeling crosses so many domains of expertise, and if you cock up any of them, you have a meaningless mess on your hands. And I can tell you from a software development POV (and I have 35 years of experience), they have royally cocked it up.

Yes please to this request. I’d like to know what would they say to explain the value of models’ many wrong and useless outputs?

Or perhaps, on the other hand, they could tell us what, if anything, the models get right to a standard which actually benefits us?

That is an interview I’d love to hear. Who would Gavin suggest as the absolute ace candidate to enlighten us? And, if he doesn’t think Joe Rogan is up to the task, who would Gavin suggest should provide the forensic questions?

This blog sure feels like a think tank of people telling each other what they like to hear. In the most insipid and agro ways possible. Lot of back slapping going on to make each other feel good about their opinions! Hope I learn something from you all eventually? Is this what diversity of opinion looks and feels like? because it doesn’t seem like all the opinions I see on here diverge very much from one another. actually pretty repetitive.
