Laughable new paper claims 99.999% certainty global warming over past 25 years is man-made

I was tipped off to this paper by a Tweet from SkS Reichfurher John Cook, and I started on writing a rebuttal, but discovered The Hockey Schtick had already done a complete job, so I’ve reposted it here.  -Anthony

The Hockey Schtick writes: A new paper published in a journal called “Climate Risk Management” claims a ridiculous degree of “certainty” of  99.999% that global warming over the past 25 years is man-made. The claim is made based upon climate models already falsified at confidence levels of 98%+.

According to the authors,

“there is less than a one in one hundred thousand chance of observing an unbroken sequence of 304 months [25.3 years] (our analysis extends to June 2010) with mean surface temperature exceeding the 20th century average.”

Fundamental problems with this claim [which is basically the falsified IPCC attribution claim of 95% certainty on steroids] include:

There is no statistical difference between the rate of warming over the 27 years from 1917-1944 and the 25 years from 1975/1976 to 2000:

Twowarmingperiods_compared

Climate models fail to simulate the [natural with 99.999% certainty] observed warming between 1910 and 1940

    Not being able to address the attribution of change in the early 20th century to my mind precludes any highly confident attribution of change in the late 20th century.” – Judith Curry

The IPCC’s attribution statement [and likewise this new paper is not seem logically consistent with the uncertainty in climate sensitivity

Thus, this new paper is not even wrong with 99.999% certainty

Assumed climate model forcings for CO2, solar TSI, Southern Oscillation Index [SOI] and volcanic.

The paper:

A probabilistic analysis of human influence on recent record global mean temperature changes

Philip Kokic, Steven Crimp, Mark Howden DOI: 10.1016/j.crm.2014.03.002,


Abstract

December 2013 was the 346th consecutive month where global land and ocean average surface temperature exceeded the 20th century monthly average, with February 1985 the last time mean temperature fell below this value. Even given these and other extraordinary statistics, public acceptance of human induced climate change and confidence in the supporting science has declined since 2007. The degree of uncertainty as to whether observed climate changes are due to human activity or are part of natural systems fluctuations remains a major stumbling block to effective adaptation action and risk management. Previous approaches to attribute change include qualitative expert-assessment approaches such as used in IPCC reports and use of ‘fingerprinting’ methods based on global climate models. Here we develop an alternative approach which provides a rigorous probabilistic statistical assessment of the link between observed climate changes and human activities in a way that can inform formal climate risk assessment. We construct and validate a time series model of anomalous global temperatures to June 2010, using rates of greenhouse gas (GHG) emissions, as well as other causal factors including solar radiation, volcanic forcing and the El Niño Southern Oscillation. When the effect of GHGs is removed, bootstrap simulation of the model reveals that there is less than a one in one hundred thousand chance of observing an unbroken sequence of 304 months (our analysis extends to June 2010) with mean surface temperature exceeding the 20th century average. We also show that one would expect a far greater number of short periods of falling global temperatures (as observed since 1998) if climate change was not occurring. This approach to assessing probabilities of human influence on global temperature could be transferred to other climate variables and extremes allowing enhanced formal risk assessment of climate change.

No sarcasm needed. Given the empirically-demonstrated price inelasticity of demand for petroleum products, what price maximizes profits?

I wonder if 97% of scientists agree with the report.

higley7

Of course, their data is not adjusted for the enrichment in UHI and lower altitude sites that occurred due to site dropout starting in 1991 with the fall of the USSR. Also, they have never made an honest, downward adjustment for UHI, just a token at best and increased temperature at worst.
An honest adjustment would actually involve an annually increasing downward adjustment. So, for these two stretches to have the same warming slope, I think hides the fact that the most recent warming slope actually has a lower rate of climb.

Typhoon

Going GIGO for grants.

wayne

Temps go along level, there are some adjustments made to make it appear to have quickly rose 1/2 of a degree, it stays as such for 100 years… so all along the years you can say for X months the temperature has remained above the long term mean. Even on the 1200th month! So what?
Are these climate “scientists” that blind to not see what they are saying? It means nothing of any value.

PeterK

‘Are these climate “scientists” that blind to not see what they are saying? It means nothing of any value.’
Isn’t that the whole meme of this Global Warming / Climate Change nonsense. It means nothing and whatever they do amounts to nothing. The only big advances being done in so called ‘Climate Science’ is the record amount of money being pis*ed down the drain to accomplish absolutely nothing.
What a wonderful world we live in…Me thinks it is time for the culling of the herd in the name of common sense and rational thinking. I just wish there was a place we could send all the eco-loons to so that they could get on with their utopian dreams and live in their nirvana state and leave all the rest of us alone to get on with our lives.

FYI Anthony, your link to “SkS Reichfurher John Cook” sends the reader to your WUWT article, but it also has a drop down that won’t allow access to see your WUWT page. The drop down says:
“To view this page, you must log in to this area on http://www.sksforum.org:80:”
Don’t know what is causing the problem, but am guessing you don’t want your own WUWT articles that you link to, to be restricted from review.

Not sure this is an appropriate phrase, no matter what we might think of John Cook. Surely we have been asked not to use the letters ‘SS’ for Sks so why do we get into the ‘denier’ meme by calling him a reichfuhrer?
tonyb

gaelansclark

The guy photoshopped himself with a nazi uniform on. Have you not seen that? He gets called what he dresses himself up ass. (Spelling intended.)

John Endicott

tonyb, it’s a reference to Cook’s photo of himself in Nazi uniform. If he doesn’t want to be a reichfurure then why did he dress himself up as one?

amos

I agree, the man is an incompetent alarmist, not a Nazi. No reason for us to take the low road, there’s a LOT of traffic down there, it’ll take us forever to get where we’re going…

John West

Step 1: Create a crisis that will be perceived as unsolvable by democratic processes/institutions with the right propaganda dissemination.
Step 2: Convince public that emergency powers need to be granted to an authority (i.e.: Chancellor, UN) in order to solve the problem.
Step 3: Expand emergency powers of the authority as the problem threatens to spiral out of control.
Step 4: Drop all pretense of solving the “problem”. Declare yourself The Emperor, or Fuhrer, or whatever you want since you’re in charge and there’s nothing anyone can do about it, except perhaps those pesky rebels … er, uh …Allies … um … skeptics.

DayHay

If I am a climate denier, then Cook is a climate Nazi, pretty simple.
REPLY: A year ago I would have snipped this comment as being over the top, but when we find that the SkS kidz play Nazi uniform dress up on their secret forum, I’d say the if the uniform fits, the name fits too. – Anthony

Pardon the pedantry, but it’s “Reichsführer-SS”, not “Reichfurher”. If you can’t make an umlaut, then put an “e” after the “u”. As in English, the “s” makes the noun genitive in case, ie possessive.

John F. Hultquist

In 1960 I reached the height of 6 feet and zero inches. Today, I am a tiny bit shorter but still above the average for the past 846 months. This is more than twice the count of the study’s monthly run. I don’t know how many 9s might be necessary to express the chance of this happening. Maybe one of the authors can figure this out. But really, who cares? They have yet to get anything right!

I copied the following from the link provided for this piece of research:
‘To conform to the approximate physical relationship between greenhouse gas concentration and temperature, eCO2 was converted to a radiative forcing value using the approximation f(eCO2) = 5.35 loge(eCO2/278) (Myhre et al., 1998). These relationships also imply that temperature (in a closed system) increases linearly with the radiative forcing value of an input, suggesting that a multiple linear regression is a suitable approximation for modelling the global mean temperature anomaly.’
Please bear with me. I’m now going to copy several weak words of certainty from the paragraph above:
“approximate”
“approximation”
“imply”
“suggesting”
“suitable approximation for modelling”
Now, can someone please explain to me how the foregoing may “imply” or “suggest” a 99.999% certainty about something? Ok, how about implying a 99.99% certainty? Or, how zee ’bout suggesting a 99.9% certainty? 99.0% certainty? 95%? How about, maybe, even something better than a 50% certainty? Or, maybe we can turn it into a 99.999% suggestion?

Bill H

They Lied? or are they just misleading? Or is it a concerted attempt to cloud up reality so that they can get more money to study it? OR they simply think that those who will read it are so ill equipped to render a reasonable judgment of their fantasy that they mixed low certainty words in with their fantasy high certainty numbers? So many logical possibilities.
A wise old Indian once told me to beware of men with forked tongues. They are evidenced by those who say one thing to one person while telling another by their actions. In this case it is clearly evident in their writings that they are speaking out of both sides of their mouths. That is the only thing 99.9999% certain in this paper other than it being a failure.
Sadly Climate Science has gone the way of Witch Doctoring..

PiperPaul

High precision, low accuracy. For activists and politicians dressed-up as scientists and using statistics this outcome is a no-brainer. Add in powerful software/computers and gullible news media plus huge piles of money and it’s virtually guaranteed.

and then there’s the “closed system”; the enormous ziplock bag enclosing the earth and its atmosphere, visible only to the authors, and 99.9999% impermeable to detection by any method available to others.

Matthew R Marler

This is another successful attempt to show that if you assume that there would have been no background warming then you can conclude that there would have been no background warming — and with great confidence and a low p-value.

Pachygrapsus

Actually they have explained the warming on the early to mid 20th century. It was “natural variability”. See, there was some natural stuff that varied and it caused temperatures to rise. During the latter part of that century all of the natural stuff stayed exactly the same but we did things to mess it up. It’s just a coincidence that the two warming periods look identical because they couldn’t possibly have the same cause. The temperature was perfect back then, correct to 3 parts in a thousand. It was too cold before and too hot now, so we need to undo the unnatural variability and keep the natural part.
It’s hard to tell but I’m waving my hands around really hard while I explain this so that you’ll know that I’m right and I can do climate science. I wonder if NASA is hiring?

Wave your hands around harder and ask Gavin Schmidt. http://www.realclimate.org/index.php/archives/2014/09/on-arguing-by-analogy/comment-page-2/#comments
(you can’t wave your hands around as hard as Gavin Schmidt, though)

Michael D

Maybe they’re saying that there was no actual warming over the past 25 years and that the reported warming is just due to man-made adjustments to temperature records?

According to some politicians, there is no such occurrence as global warming. I personal believe that there is global warming and it is man-made. There is no getting around it. The world is slowly changing and it doesn’t matter how messed up the environment continues to be because people don’t believe in global warming. Goodness!

joelobryan

Southern,
Science is not based on beliefs. Church, faith in a supreme creator, and monotheist religions are the realm of beliefs. Science is based on falsifiable hypothesis. Beliefs are what has caused all the problems we now face with the like of 350.org, Al Gore, et al.

well thank you for your insight. (eye roll)

Eric

Yes, the world is changing… just has it always has for the past 4 billion years. Climate has always changed as well. The world is not the static system that the warmists want you to believe it to be.

ok. thanks

Gal, you forgot the Sarc tags in your posts..

MangoChutney

What do politicians know about anything?
Yes, towards the latter part of the 20th Century the earth warmed and it is highly likely man caused some of the warming (concreting over large areas, deforestation etc must have some effect). The question is how much warming v natural, is CS high or low and will any warming be catastrophic, dangerous or benign?

But SouthernGal. The world has stopped warming ca. 1998. Granted, the news don’t tell you this. But the RSS measurements do:
http://woodfortrees.org/plot/rss/plot/rss/from:1998/trend
Indeed, if the world were warming, I would probably think that the climate modelers have created working models.
But, as their models show warming, while the satellite measurements show non-warming or even cooling, I now think that
a) the climate modelers have exaggerated their competence greatly
b) politicians were all too eager to use this pretense of knowledge to inflict all kinds of taxes on the populace
c) The journalists are too incompetent to understand but very eager to sell a future catastrophy.
You see, it is measurements that tell me that all this is the case; not beliefs. Of course, my personal experiences with the weather coincide with the measurements. It is not warming.

Man Bearpig

Well, everyone is entitled to hold their own beliefs. Some believe in this others believe in that, there is no problem. No one has, or should have a problem with that, but when others start imposing their beliefs on others it becomes very dangerous.
The Catastrophic Anthropogenic Global Warming theory has a problem, there is no discernible evidence to say it is true because the ‘proof’ is based on predictions of the future (‘the temperature will be x degrees, sea level will rise, there will be more this and that and less other’ ) the vast majority of such predictions in AGW field have so far not been accurate, but have been very precise in being inaccurate (temperatures to 0.001 degrees, etc.).
Unless you can point us to factual measurable evidence of AGW it remains a theory, and I remain sceptic.

Well, there used to be global warming but it stopped a few years back, which is too bad because global warming is a very good thing–it prevents global cooling. People like to live in the South because it’s warm. Northerners like to move to the South, but Southerners don’t like to move to the North because it’s cold. Detroit is full of empty houses that nobody wants to live in because it’s warmer down south.
But now global warming is making it colder which makes it even worse–no matter how much carbon we burn to keep warm global warming makes it colder. We’ll all have to move south to save ourselves from global warming. Move over, SouthernGal! –AGF

Alrighty then

Duster

At most time scales over the last half-billion years, the trend is cooling, not warming. You have to be pretty careful of endpoint selection in fact to get a warming trend. The planet has been warming since the end of the Little Ice Age, but cooled since the Medieval Warm Period. It has been cooling since the Roman warm period, and in fact has cooled over the last 8,000 years or so. It has warmed since the maximum of the Wisconsin glacial (about 19 thousand years ago), but cooled over the last 130,000 years or so (since the Sangamonian or Eemian interstadial). Push back to about 5-million years and the over all pattern is a continuous cooling. Cooling has dominated the 150 MY or so. The last time the planet averaged as cool as it is at present was around 250 to 300 million years ago (the Permian).
We commonly assume that humans “must be having an effect,” but until someone can really explain the workings of natural weather (climate is just weather over long time spans) we can’t sort out just what humans really are doing.

Thank you for the book report! Its not that serious. lol

Uncle Gus

SouthernGal, you can believe in global warming. You can believe the Moon is made of green cheese. But there’s a temperature record, which everyone agrees on including all the climate scientists. It shows no warming for 17 years.
I hate to say this, but what you believe doesn’t matter.
(And there are guys who have walked on the Moon who can testify to a complete lack of Gorgonzola…)

When you get granular enough, anything that has happened is almost infinitely improbable, because there are an almost infinite number of other ways things could’ve gone. These studies are more a proof of the failure of US science education than anything else, or evidence of a basic inability to think.

December 2013 was the 346th consecutive month where global land and ocean average surface temperature exceeded the 20th century monthly average, with February 1985 the last time mean temperature fell below this value. Even given these and other extraordinary statistics

That’s all the global surface temperature metric is, a statistic. It has no physical meaning, and gives a completely false impression that all points on the planet warmed at the same rate, or that they warmed at all.

Uncle Gus

Been saying that for years. It’s a totally artificial variable, and not a very useful or illuminating one at that.

Can someone please explain how the Natural Variation of the 1900-1950 period was stopped in the 1951-2000 period? The paper some how fails to explain just how they stopped the natural stuff and then how man took over…
Silly me. I might have missed it… /sarc

joelobryan

Seems to me that since their analysis ended in June 2010 and it is now more than 4 years later, they have probably been shopping this paper around at Journals for the better part of 3 years getting rejections. Climate Risk Management is a new journal, with an editor hungry for anything to start a track record that will take years to build to get an impact rating.
As for the 1985 date for their start of global warming, how do they reconcile with the fact GHG supposedly were affecting the climate by 1950? Who knows? Probably why even most other journals rejected the paper.

Bill H

Maybe this will be their first retraction in shame.. One can hope this is a lesson learned in the school of hard knocks.. They missed some very basic Null Hypothesis things which makes me think that journal isn’t so scientific in its endeavor. Possibly a Propaganda front for the Administration.
Going to have to look closely at their board of directors and owners.

When dealing with extremists like the climate obsessed it is always good to bet they are simply cherry picking. Stopping at 2010 is certainly a cherry picking effort since more data is easily available.

Scarier than that, and much more likely – they don’t care!
For years now, I’ve been tracking the rise of “controversy science” as a career choice. There are thousands of guys out there (with perfectly good PhDs), “proving” that cellphones cause cancer, that BSE is creating an epidemic of nvCJD, that vaccination causes autism… The list is endless.
It’s a guaranteed income, because failure doesn’t cut off the money stream. In fact, if you pick the right sponsor, failure is impossible; the most pitiful of nul results can be published as “evidence in favour”, and actual evidence against… well, it doesn’t have to be published at all.
These f*ckwits – they’ve got degrees, they’re published in a real journal, what more do you want? If it said nothing but “All work and no play makes Jack a dull boy” one million times, they’d still think they were doing science.

4 Sept: Bloomberg: Sangwon Yoon/Mark Drajem: China and Indian Leaders Said to Skip UN Climate Summit
The top leaders of China and India aren’t planning to attend this month’s United Nations summit on climate change, signaling tepid support for a global pact to cut greenhouse gases among two of the largest emitters…
“I was completely shocked and very disappointed to read today that Chinese President Xi and Indian Prime Minister Modi may not make it to Ban Ki-moon’s Climate Summit,” said Tony deBrum, the foreign minister of the Marshall Islands, in the northern Pacific Ocean, in a statement. “For the small island states of the world, the science says we might be forced to pay the biggest price of all — the loss of our countries. We expect solidarity from our developing country compatriots, not excuses.” …
“The issue for us is really on the commitments that countries will bring and the secretary general expects member states to come with strong and bold commitments on climate change,” Ban’s spokesman, Stephane Dujarric, said yesterday in New York. He said he has nothing to add when asked about the leaders’ attendance…
The summit comes as scientists are increasingly warning of the risks of climate change…

I think this is all above board and we are clearly responsible for 99999.999999% of warming except when it’s cold, in which case it’s weather.
After all, how else could a brand new journal publish a brilliant paper by 3 authors based at CSIRO, when the editor in chief is also from CSIRO and James Hansen as an associate editor?
Very clever of the authors to avoid the £1500 fees by submitting during the special offer period. Of course if they’d waited until next year they could have taken advantage of the BOGOF promotion.

I went looking for the masthead, editor, or editorial board of the Journal. I could not find one that wasn’t behind a paywall.
I did find the authors of Vol 1, No. 1, page 1-4, “What is climate risk management?” So I make the assumption that these two authors have something to do with the management of the journal.

“There is less than a one in one hundred thousand chance of observing …”
But the prosecutors fallacy is much more common.

Jordan

In reality, there is less than one in one hundred thousand chance that THEIR BOOTSTRAP SIMULATION would produce the observed data. From this, we have two alternative conclusions:
Conclusion A: (the authors’ claim) “This method provides a rigorous probabilistic statistical assessment of the link between observed climate changes and human activities”
or
Conclusion B: “This method provides a rigorous probabilistic statistical assessment of the relationship between climate and CO2 in the model, and model validation to the same 1-in-100,000 standard is now demanded to support a link between real-world observed climate changes and human activities”
They cannot have “A” without “B”. Their claim is groundless until they produce the validation to the above standard.

The practical question is the following.

Their models, when they work, fail with 98% confidence,
HOW exactly, then, do they figure out when their models DON’T work?
Is it that they make their computers put out smoke, like in the 60’s B-movies?

Watch how the climate obsessed like Trenberth and the authors of this paper, have turned from telling us the “IPCC is the gold standard” to telling us now that it is not extreme enough. They flail away with excuses looking for heat that is not there and desperately seek to distract policymakers from the failure of their models.

Or they desparately seek to distract scientists from perceiving that the failure of their models is unrelated to the goals of policymakers.

Reblogged this on ScottishSceptic and commented:
The claim of 99.999% is so utterly ridiculous that I can’t believe anyone seriously wrote it.
However, Anthony’s put together a very concise summary debunking this whole “it must be man-made” claim. The 1910-1940 warming is key – because that warming must be largely natural, and by inference whatever caused that could easily be responsible for the 1970-2000 warming. How unlikely that is depends on the noise model you assume, however based on my assessment I’ve always (since at least 2009) said that “the 1970-2000 warming is entirely consistent with natural variation and cannot be distinguished from noise”.

Cheshirered

This is surely intended for roll-out alongside the ‘97% consensus’.
Simply a PR line to be parroted by activists and useful idiots. That it’s plainly nonsense doesn’t concern them. 99.9% Propaganda.

Abstract:
“We construct and validate a time series model of anomalous global temperatures to June 2010, using rates of greenhouse gas (GHG) emissions, as well as other causal factors including solar radiation, volcanic forcing and the El Niño Southern Oscillation. When the effect of GHGs is removed, bootstrap simulation of the model reveals that there is less than a one in one hundred thousand chance of observing an unbroken sequence of 304 months…”
Wikipedia defines:
“Time series data have a natural temporal ordering. This makes time series analysis distinct from other common data analysis problems, in which there is no natural ordering of the observations …. A stochastic model for a time series will generally reflect the fact that observations close together in time will be more closely related than observations further apart. In addition, time series models will often make use of the natural one-way ordering of time so that values for a given period will be expressed as deriving in some way from past values, rather than from future values.”
As a tool “bootstrapping” is only valid mathematically (and logically) if each observation is independent of its neighbours.
The authors are children playing with toys that they do not understand.

Let me see if I understood their model: the model explains temperature change as a function of various inputs. One of these inputs happens to be greenhouse gases. The model is calibrated to have temperature respond to the input values
As far as i can see CO2 and other greenhouse gases do influence the climate. The question in my mind is how much influence do they actually have?
A model like theirs can be calibrated to give CO2 a strong influence (they just have to emphasize achieving a match to a relatively short history with emphasis on the mid 70’s to 1999 period, when temperature rose rather fast).
Then they jog the model by changing CO2 concentration. As far as I can see their results were preordained because their watch overweighted CO2 and other gases by ignoring the long term climate cycles.
By coincidence I was looking over USA oil production history over the last few days after reading about Daniel Yergin’s oil production forecast (Yergin is a famous oil industry wonk). Because I do happen to have some expertise in the field I decided to research existing forecasts as well as prepare my own. As I did I realize there were some similarities between the way we prepare oil production and climate models.
So I decided to write a short memo about this issue in a non serious way (it’s called “Forecasting the Future”). I stuck it here
http://21stcenturysocialcritic.blogspot.com.es/2014/09/forecasting-future.html
Please note I aimed at showing both the problems one faces when using a history match to predict the future (I used a simple excel example, it’s not supposed to be rocket science).
But I also wanted to remind you I’m worried because we ARE running out of oil. And this is the reason why sometimes you’ll see I’ve written positively about things such as a carbon tax. Personally I see a carbon tax as a positive AS LONG AS THEY DROP MY TAXES ELSEWHERE (income tax reductions to offset the carbon tax income would be just fine with me).

“we ARE running out of oil” You don’t acknowledge the evidence that oil is an abiotic, renewable resource rather than a fossil fuel? How do you explain its presence at a depth of 40,000 feet below the earth’s surface?

Cassidy421, I don´t accept that oil is abiotic. I assume posting links to the anticorruptionsociety and democraticunderground sites is a joke?
I assume you do know a normal land geothermal gradient would yield about 500 to 600 degrees Farenheit at 40 thousand feet? That´s 260 to 310 degrees C. Oil molecules don´t hold themselves together at those temperatures. They break up and gradually change to natural gas molecules. Given enough time they turn into CO2.

High Treason

99.999% certainty there is something very fishy about this claim, especially with the growing disparity between the cold, hard observational data and the models. Perhaps they are 99.999% certainty the models say what the models say. Why needs observational science when models will say what you want to hear.

Gary in Erko

99.999% is better odds than the almost 90% vote at the election of the president of Syria a couple of months ago, and that was a big drop from Assad’s 97.6% in 2007.

Maybe they are actually talking about Ivory Soap, and made a typo.

Assuming these authors are Australian Climate scientists like SKS people who are about to lose their jobs or have been advised that there will be no more gov funding as of 1st Jan 2015-2016? They are really stupid …no one will want to employ them for anything in the future (maybe floor cleaning)?

Man Bearpig

No, not even floor cleaning, the people are nothing to do with science, they are activists pretenders. Would you employ them? Perhaps they may get a job in big oil? I think Dana has some contacts there.

Kenny

This makes for a simple, quick statement on any of the news outlets, NBC, CBS and ABC. Can’t you just see the evening news anchors……”A new study shows man is responsible for all the warming over the last decade and a half”.
No debate….no rebuttal….just a false statement thrown out there for people to hear and claim it to be the gospel truth.

Adam

I am 100.00000% certain that catastrophic anthropogenic global warming might turn out to be a load of hot air.

Lamby

I know you guys don’t really do science or maths…
But read this article by Nassim Nicholas Taleb (Black Swan Theory). It explains that “The more uncertain or skeptical one is of models, the higher the risk of ruin, which flies in the face of the argument of the style “skeptical of climate models”. No matter how increased the probability of benefits, ruin as an absorbing barrier, i.e. causing extinction without further recovery, more than cancels them out.”

Lamby
I know anonymous trolls don’t really do thinking or provide real information …
But what article by Taleb?
And why should anyone accept your ambiguous assertion of its content?

Please quote the part of that document which you claim says what you assert.
Alternatively, define the pertinent paragraph(s).
You are making assertions. Nobody needs to do ‘homework’ to find justification for your assertions you have not justified. In truth, your behaviour is providing evidence for my statement that said

Just the graph is enough to show what Taleb is trying to assert – that (if you have a standard distribution model of probability – i.e. not a ‘certain event’) the more uncertain the models are the higher risk of a catastrophic outcome.
Are you guys are so certain that there is no human induced global warming that you will not take any mitigating steps? When there is enough good evidence that it would be prudent to take some ‘insurance’ – . If you look at the consequences, you only need something like a 5% chance of humans causing global warming for it make sense to take some mitigating actions.
The analogy is you living in a bush fire prone area, and all the ‘experts’ are telling you that you need to take out fire insurance and have some exit strategies in place to get your family out in the event of a fire. Are you going to ignore the experts and bet your family?

Are you guys are so certain that there is no human induced global warming that you will not take any mitigating steps?

Part of the art of dialogue is “listening” (in this case reading) to what others say and then responding. The statement quoted above is a clear indication you either lack the skills, or are totally ignorant of what a forum is all about.
So your challenge, should you wish to remain the least bit credible, is to show where anyone is stating your straw man. If you want to save some time, just admit you have no clue what you are talking about.

Owen in GA

Lamby,
It is nothing like a bush fire prone area. There you can see the tinder dry vegetation all around you so the probability of a fire is high by direct observation.
In climate science, we see around us lush green vegetation with an inch of rain per week falling, but some grant monger is yelling in our ears that just beneath the surface is an inferno that will engulf us all and it is worse than we thought. Their models show that we are “ALL GOING TO DIE”. Meanwhile we continue to see lush green growth and an inch a week of rain.
So your set up is a classic strawman with all the trimmings.

Lamby
You incorrectly assert

Just the graph is enough to show what Taleb is trying to assert – that (if you have a standard distribution model of probability – i.e. not a ‘certain event’) the more uncertain the models are the higher risk of a catastrophic outcome.

Clearly, you failed to read the paper you have cited.
That graph applies to a normal distribution. In other words, it is not an applicable model for climate which – of course – their performance demonstrates is also the case with the numerical climate models.
The remainder of your post is paranoid idiocy.
You would never get out of bed in the morning if you believed “the more uncertain the models are the higher risk of a catastrophic outcome” because there are very many potential “catastrophic outcomes” from very many poorly modeled situations throughout each day.

Lamby….. I doubt that people are skeptical of climate models. They are skeptical of the Alarmist’s gigo climate models.

“I know you guys don’t really do science or maths…”
Yawn…
Of course, that’s as far as I got, and I’m damn sure I’m not the only one.

I believe the not stated assumption by Taleb would be that the models are reasonable, relatively science based.
The CAGW models arguably are not since they do not match up to reality.
Therefore, the further assumptions you make are not valid for CAGW models.

Lamby, I’m pretty sure there’s some influence by GHG on the climate. I assume by now most people realize the debate centers around climate sensitivity and the nature of the forecasts being prepared by some parties (such as the IPCC’s CMIP5 ensembles using RCP8.5).
I see this as a multiple set of points of contention. I’m not a “denier” nor I’m I scientifically illiterate. I also happen to know more about complex model work flows than the majority of the scientists in the fake 97% quoted by President Obama (who by the way got my vote in 2008 because I hated McCain after he picked Palin and sang that stupid “bomb Iran” ditty).
The problem I see with your comment is that we read a lot of material written by watermelons and other suspect characters, we get told certain nations expect “reparations” because they got to hide from sea level rise, and to top it off we see idiocies like the solar power plants installed in Spain and Germany. So you see as far as I’m concerned the fundamental problem is caused by yahoos trying to take over the political system to impose their pet solutions, most of which happen to be impractical, sometimes they are even worse, they are absolute garbage.

What about 2012?

Sturgis, I didn´t vote in 2012. By the time November rolled around I had forgotten to ask the US consulate for my expat voter envelope, and I was too wasted to fly to Texas. Besides, I don´t think it would have made much difference. I focus a lot on US foreign policy ( I usually live outside the USA). Both parties are terrible in that area.

The key to a useful model is that it replicates with confidence, the workings of the process being modeled. No one has so far produced a climate model for which that is true, except when expressed as a matter of faith by the modeler. When a model is known not to function as expected, then using that model results in the blind-blind-ditch scenario if you persist in employing it. You want to consider Taleb’s argument in the light of existing knowledge – that is, apply some Bayesian reasoning.

joelobryan

Societies throughout history can and do choose to follow courses of action based on the emotions of fear and ignorance. That is what is happening now. That is what the IPCC, Al Gore, Bill McKibben and all their ilk are betting on. The gullible masses have been preyed upon by charlatans since the dawn of mankind.
So you are entitled to a personal opinion and belief.
Just don’t call it Science, when those ringing the alarm bells are trying to stifle scientific debate with statements like “settled science” and the “debate is over.” At that point, history would advise that one should put a tight hold on your wallet, as the sticky-fingered charlatans are coming for what’s inside.

You’re 180.000004% correct, of course. The real insanity is that this was explicitly stated in the Club of Rome’s PUBLISHED report in 1972 and here we are in 2014, after 22 years of IPCC fraud, still trying to pretend it’s real, and ignoring REAL environmental problems. AGW was fabricated as an excuse to murder 95% of the world’s population, and the need to do that was justified by computer modeling by the Club of Rome that’s as absurd as IPCC’s modeling. The Club of Rome was founded by oil billionaire David Rockefeller in 1969 from members of the Committee of 300 to develop a plan to achieve a global fascist totalitarian takeover, and AGW is the plan, implemented by Agenda 21. They stated that a fabricated environmental crisis was a way to hide their agenda and formed the IPCC to hide their involvement. (CoR is a UN advisory group).
““The common enemy of humanity is man.
In searching for a new enemy to unite us, we came up
with the idea that pollution, the threat of global warming,
water shortages, famine and the like would fit the bill.”
“The real enemy then, is humanity itself.“
Club of Rome
Quote from CoR member John Holdren ‘s book, Ecoscience “Perhaps those agencies, combined with UNEP and the United Nations population agencies, might eventually be developed into a Planetary Regime—sort of an international superagency for population, resources, and environment. Such a comprehensive Planetary Regime could control the development, administration, conservation, and distribution of all natural resources, renewable or nonrenewable, at least insofar as international implications exist. Thus the Regime could have the power to control pollution not only in the atmosphere and oceans, but also in such freshwater bodies as rivers and lakes that cross international boundaries or that discharge into the oceans. The Regime might also be a logical central agency for regulating all international trade, perhaps including assistance from DCs to LDCs, and including all food on the international market.”
These people are the most insane, destructive psychopaths in the history of the planet, people who have repeatedly used false flag events to start wars, funded both sides of wars and benefited from arms sales and debt service, created famines by manipulating prices, created bioengineered pathogens to cause pandemics, manipulated interest rates to cause housing foreclosures, engineered the 1929 stock market crash, and they control all international markets. Their current plan is confiscating all assets and creating a global serf state with only a sufficient number of people to serve their needs. They didn’t acquire their money and power through superior intelligence or knowledge or skills, but by being psychopathic predators with no conscience; “not quite human”, according to Robert Hare, who developed the checklist used in diagnosis: psychopaths process emotional input differently from normal humans, and have structural differences in their emotional processing centers (limbic system, amygdala).
Environmentalists “know” that anyone who doesn’t support AGW is owned by an oil company, and scientists concerned about the environment (including me) are focused on scientific fraud and deception, and these are both diversions; perception manipulation The goal of AGW is global domination and control of all assets, no rules, no truth, no ethics, no science. Who’se left? The segment of the population with no means to detect the fraudulent science and who unquestionably support authority. Scientists who are able to understand that climate science is misrepresented are the only segment of the population with any power to attack the politcal cabal that’s promoting AGW solely for its own agenda.
