Guest essay by Patrick J. Michaels
Day after day, year after year, the hole that climate scientists have buried themselves in gets deeper and deeper. The longer that they wait to admit their overheated forecasts were wrong, the more they are going to harm all of science.
The story is told in a simple graph, the same one that University of Alabama’s John Christy presented to the House Committee on Natural Resources on May 15.
The picture shows the remarkable disconnect between predicted global warming and the real world.
The red line is the 5-year running average temperature change forecast, beginning in 1979, predicted by the UN’s latest family of climate models, many of which are the handiwork of our own federal science establishment. The forecasts are for the average temperature change in the lower atmosphere, away from the confounding effects of cities, forestry, and agriculture.
The blue circles are the average lower-atmospheric temperature changes from four different analyses of global weather balloon data, and the green squares are the average of the two widely accepted analyses of satellite-sensed temperature. Both of these are thought to be pretty solid because they come from calibrated instruments.
If you look at data through 1995 the forecast appears to be doing quite well. That’s because the computer models appear to have, at least in essence, captured two periods of slight cooling.
The key word is “appear.” The computer models are tuned to account for big volcanoes that are known to induce temporary cooling in the lower atmosphere. These would be the 1982 eruption of El Chichon in Mexico, and 1992’s spectacular Mt. Pinatubo, the biggest natural explosion on earth since Alaska’s Katmai in 1912.
Since Pinatubo, the earth has been pretty quiescent, so that warming from increasing carbon dioxide should proceed unimpeded. Obviously, the spread between forecast and observed temperatures grows pretty much every year, and is now a yawning chasm.
It’s impossible, as a scientist, to look at this graph and not rage at the destruction of science that is being wreaked by the inability of climatologists to look us in the eye and say perhaps the three most important words in life: we were wrong.
This article appeared in TownHall.com on May 29, 2015. Patrick J. Michaels is the director of the Center for the Study of Science at the Cato Institute.
Thanks, Dr. Michaels.
This is an excellent essay.
There are several responses to a continue pause, and or cooling:
1. (Already seen) The excess heat is being stored in the oceans and will roar back with a vengeance, any year now.
2. We missed some dynamic in the climate models that causes cooling, but CO2 will soon overwhelm this dynamic and warming will soon return with a vengeance.
3. What? We never predicted warming. Those were fringe publications by scientists of no import. CO2 causes climate disruption, and we’ve pumped so much of it into our atmosphere so quickly that we’ve prematurely caused the next ice age.
I think #3 might be fun, and likely if we see a significant fall in temperatures in the coming decades. Remember, it’s all about alarmism driving government action. If you’ve got a looming ice age, screw the fig leaf of scientific integrity #1 and #2 might give you, ICE AGE!!
Joshv, yup. It is alarmism. That’s the game
PolSci? I remember when a Political Science course didn’t have
anything to do with “the earth has a fever”.
When Will Climate Scientists Say They Were Wrong?
Climate scientists will admit that all of the scientific premises of the IPCC were incorrect, including the general circulation models (GCM) when the planet abruptly cools and when atmospheric CO2 drops.
Cooling of high latitude regions has started.
The initial reaction of the cult of CAWG has been to ignoring the high latitude cooling. The cult of CAWG response has been keeping up the campaign of calling those who point out the hundreds of independent observations and analysis results in peer reviewed papers that disprove CAWG ‘deniers’.
Based on what is currently happening to the sun and how the climate has changed in the past when there was a similar abrupt change to the sun (best analogue is the 8200 years before present cooling event) there will be roughly 0.7C to 2C cooling. The question is how fast and how much cooling there will be rather than will there be any cooling.
As the planet starts to significantly cool, political support will disappear for CAWG. Significant abrupt cooling will be a major media subject which will accelerate the paradigm shift in climate change beliefs and the end of CAWG/green scams.
It will be interesting to listen to the initial creative explanations to explain the start of cooling and the attempts to keep CAWG on life support.
What amazes me is the almost total avoidance of any commentary by Mosher about the failure of the models. I think he had a couple of simple one liners, but otherwise has zip to say at all. Amazing. Of course Lukey is up to his old tricks avoiding actual data and observations. He haunted the Marohasy blog for years and just loves his data if it can be used upside down ala some of the Tiljaner stuff etc. And where is Nick Stokes?
No need for them to provide one-liners and other tidbits. We have William to entertain us.
Pamela can not entertain opinions that differ from her opinion which makes no sense at all.
Science is not Opinions. Pseudo science and wishful thinking are.
Sal, when temperature data sets, on the ground or from satellites – you pick, are compared to any and all observed solar data sets as well as quality reconstructions, there is no correlation. There are those who massage the data sets till the elephant’s trunk is made to not only wriggle but sing a very bad version of our national anthem. I recommend we plug our ears, let alone our nose.
Observed temperature data does not match solar data. That some here continue to look for solar unicorns degrades the level of science acumen assigned to this blog, much like these singers degrade our national anthem.
Pamela,
Global temperature correlates very well with solar activity. During the Medieval Warm Period, for instance, there were only two brief, shallow SSN minimum, the short Oort, in the middle of it, and the longer Wolf, well towards its end, which could be attached to the LIA, into which the world was transitioning during it.
The LIA by contrast included the big Maunder Minimum and the deep Dalton, with less recovery between them than during the MWP. The Modern Warm Period, by contrast, has been associated with an exceptionally active sun and as yet not major minimum such as those mentioned.
What you claim are just coincidences and myths [which you help to propagate]. And the various Grand Minima were not all that grand (e.g. the Dalton). Here is our latest estimate of solar activity the past 400+ years. There is no correlation worth talking about with temperatures:
http://www.leif.org/research/Fig-37-Estimate-of-Group-Number.png
Any sunspot cycles graph is only as good as its last haircut.
Leif,
What you call a myth, I call an observation. That you have dedicated yourself to “adjusting” the observational record doesn’t invalidate the authentic data from all sources supporting prolonged, low solar activity during those intervals.
I see I forgot the Spoerer Minimum. My bad. Sorry. It was the first of the three, not two, LIA minima. Or second of four, if you attach the Wolf to the LIA.
Some rear-guard reaction is to be expected to any adjustments, no matter how justified. And it is not ‘my’ adjustment, but the combined work of dozens of solar physicists.
Sturgis, you do realize that much of the reconstruction work has been focused on unadjusting previously adjusted data. Yes?
Pamela, I don’t think that matters as bad data and bad science will live as long as they supported some people’s agenda and beliefs.
In science nobody ever admits they were wrong. It’s not just climatology either: http://wp.me/p4JijN-81
Science’s power is that it can be shown and proven wrong, and has done in the past. When the evidence proves it. I think you are confusing science and “what goes on in your mind”.
That’s a useless cliche. Find a new hobby.
i am the Director of 3 DNA testing laboratories, so I don’t have a hobby in science. So, as nice as it is that you want to advice me in someone you are untrained, uneducate and unqualified in. I don’t think your comment is fair or honest. What do you do? Whatever it is, I am very very sure, you would not appreciate me, or any other ignorant person walking into your work, and telling you how to do your job.
I generally believe we have far too many laws, but perhaps we need at least one more.
More than once in my lifetime, deliberately fraudulent, peer-reviewed research has resulted in creating sociatel problems. The faked vaccination/autism research has led to deaths. Faked research on the historical use of guns in America resulted in flawed legal decisions. In the last week, faked research concerning acceptance of alternative lifestyles was exposed, fortunately before becoming yet another death-defying meme.
Why hasn’t the act of seeking publication of peer-reviewed research that purports to be factual, but is instead fraudulent, been made a criminal act? I frequently read retractionwatch.com and am appalled at some of the things that are happening in peer-reviewed literature.
I don’t know if it would change much, but maybe some scientists would think twice before making unjustifiable adjustments to data if they believed it could be perceived as fraud.
Note that there is a big difference between fraudulent research and research containing honest errors (e.g., the original DDT eggshell-thinning study).
Why we are at it. Include false reports of all types. People do incredible harm, when they lie, or post false reports, as many deniers do. Gullible people love to soak up information that fits their beliefs, and almost never believe real data and evidence that disproves their beliefs. So ridiculous that any blogger, politician or denier can overwrite, smear, and blacken solid science.
Vern Muir
Please name one. We DO have hundreds of lies and exaggerations and self-promoting hypocritical propaganda directly from the government-paid climastrologist catastrophe religion you appear to worship below.
When you accuse me of “worship” tells me that you are against all science, in all disciplines, and assume every scientist is dishonest. Not a single hardworking family man exists? No one is honest? Every report faked? From NASA….fake. From Australian Bureau of meteorology…faked. Norwegian glacieologists….faked. Right? Every single one? Everyone around the world working together to lie, manipulate and cheat? So, if I have to doubt hard evidence, otherwise I am worshipping it? That is just outrageous and you know it. You claim I worship our hardworking, honest men and women. Well I support the troops. Risking their lives in Antarctica, sometimes fatally.
http://www.theguardian.com/vital-signs/2015/may/01/deaths-arctic-researchers-ice-climate-change-cornelissen
You come across as an arm-chair self-prescribed expert, typically completely uneducated in science, no training, no knowledge, no background, no honest investigation or research, with a desire to jump on the band-wagon to worship the ideas of conspiracy, ironically without evidence of any hoax.
So, easy to invent doubt, much harder to go into Greenland and risk your life to drill ice cores. Then our VETS come back to put down by people like you.

Good graph. Thanks.
the Observations are wrong scaled in this Graph. They are twice of that shown here, by 0,4 not 0,2°C!!!

IPCC AR5 Figure 1.4. Solid lines and squares represent measured average global surface temperature changes by NASA (blue), NOAA (yellow), and the UK Hadley Centre (green). The colored shading shows the projected range of surface warming in the IPCC First Assessment Report (FAR; yellow), Second (SAR; green), Third (TAR; blue), and Fourth (AR4; red). IPCC
Since 1990, global surface temperatures have warmed at a rate of about 0.15°C per decade, within the range of model projections of about 0.10 to 0.35°C per decade.
But, since when has any of the deniers cared about real data, real evidence and real scientific consensus?? Never. They just link to some dodgy website, believe hundreds of organisations are in a giant conspiracy, and every scientist is dishonest and making up results to get funding!! Ironically, all without evidence.

Despite the data.When will Climate Scientists admit they were wrong?
When Hell freezes over…. Which if current trends are anything to go by, might be sooner than you think 🙂
Not even when Hell (or earth) freeze over. The Team will be urging action to prevent the coming ice age before they ever admit they were wrong about AGW.
The softening of the APS’s new draft statement on climate change implicitly concedes the earlier one was over the top. If other scientific societies periodically re-issue their position statements, the softening revisions they make will implicitly concede (very clandestinely) prior excess. OTOH, if they don’t soften and the climate continues to plateau, they’ll look even worse in the end.
Do you have a link to the new statement?

I think there is something wrong with Pat Michaels graph. Both RSS and UAH show a large average annual increase in 1998 compared to 1997 or 1999 …. about a 0.4 degree C difference. But I do not see that in his expression of the data. Are thiose gree squares annual averages ? Are they running averages (over 5 years, like the red line) ??
Yes (to your second question).
it is diffiucult to understand why the scientific community is not up in arms at the IPCC’s reliance upon models, and the plitical mantra that the science is settled.
If the science was truly settled there would be only one model, or only 3 or 4 different models each based upon different CO2 emission scenarios, eg Hansen’s A, B and C scenarios.
The question that warmists should be asked should they cling to the ‘science is settled’ is to identify which one of the 102 models is based upon the settled science for CO2 emission scenario A, which one of the 102 models is based upon the settled science for CO2 emission scenario b, and which one of the 102 models is based upon the settled science for CO2 emission scenario C?
if they are unable to identify the model in question, then it is clear that the science is not settled.
The average of wrong is wrong. Averaging lessens the width of the error margin, but it never makes the cummualive of incorrect data correct. Dr brown has often commented upon the problems with the IPCC’s approach to model projections and the averaging thereof, and those comments should always be bourne in mind when considering the scientific worth of these models and the GIGO projection.
After 25 years or so of climate research and many billions of dollars thrown at climate research the climate scientists would have one believe that no progress has been made with the assessment of climate sensitivity. That is a travisty and an admission not simply of failure but also that they do not understand the most fundamentals and basics of the science which they claim to be exploring. If the science was well understood, it would be possible to narrow the range of climate sensitivity.
Of course, everyone knows, but refuses to admit that climate sensitivity cannot be high. The fact that there was no temperature increase according to the satellite record between 1979 and in the run up to the Super El Nino of 1998, ie., a period of more than 18 years demonstrates a low sensitivity. The fact of the recent ‘pause’ (the second pause in the satellite era) which extends for more than 18 years, again demonstrates low sensitivity. The satellite era and the measurements made clearly suggest that any sensitivity to CO2 is below the threshhold of sensitivity the measuring equipment such that no signal to CO2 is discernable in the satellite data set (which set corresponds with balloon measurements).
The satellite data suggests that the warming that has taken place since 1979 is a one off step change in and around the Super El Nino of 1998 and was brought about by natural not manmade causes. the satellite data suggests that there may be no sensitivity to CO2, but a more accurate conclussion is that teh sensitivity is so low that it is not discernible within the margins of sensitivity of our best measuring equipment. Depending upon the sensitivity of that equipment and the error margins, there is scope to keep aliive the claim that CO2 may drive temperatures, but not at a rate above natural variability.
In any other science the high sensitivity models would have been abandoned long ago. There can be no justification for not abandoning these, but as others have noted they are kept not for scientific reason but because they are necessary to boost the average projection into the so called scary region.
However, if the ‘pause’ continues into 2019, and god forbid if there is some cooling following this year’s El Nino (if that evelops as looks reasonably likely), it will be very difficult for the IPCC not to address the climate sensitivity issue (it side stepped that issue notwithstanding that several papers have been published in the 24 months prior to AR5 suggesting modest sensitivity) and the fact that all the models are outside the 95% confidence level (if the ‘pause’ continues all the models will all be outside the 95% band).
At the time that the drat AR5 was being circulated, I suggested that there would not be an AR6 for the above reasons. As the ‘pause’ continues and lengthens (should that happen over the next 4 years) there will be more and more papers dealing with climate sensitivity and each of these will suggest lower and lower sensitivity. That must be the case. This is why Paris 2015 truly is the last stop cafe. If no deal is done (and that looks impossible given China’s and India’s position), the fate appears cast that there never will be a global deal effectively and significantly cutting CO2 emissions since it appears that the wheels are fast falling off the CAGW wagon. The final death knell will be a cold winter in Europe and/or the states with brown outs. That will really waken up Joe Public to smell the coffee.
They are not up-in-arms, as unlike you, they are not manipulated by a deniers website. There were various models, and of course, this website only shows the most extreme one, and as predicted all the arm-chair experts, with no education in the science, are up-in-arms over something they really know very little about. Attend a conference, get a degree, read 3 dozen papers, then write your big rant, this time without the one-sided slant. Details are always up for debate. What is settled is 1. CO2 heats the atmosphere. 2. Humans pump known volumes of CO2 into the atmosphere. 3. Our CO2 levels are higher than naturally events can account for. 4. We are heating more than nature can account for.
All the details, models, speed of change, and what we do about it, is all up for debate. It is just juvenille to point out a detail in error and then claim everything is “wrong wrong wrong”. That is like using a plane crash to prove air-travel is impossible.

(try to stay up to date too).
They will continue to make outrageous claims. Here’s a news clip of NASA scientist Dennis Bushnell telling us that sea level will go up between seven and eight feet by the end of the century. That requires an average rate of over 28 mm/yr starting right now, or a steady acceleration of 0.6 mm/yr² for the next 85 years yielding a final rate of sea level rise by the end of the century of nearly 55 mm/yr or a millimeter per week. He might as well be telling us he was born on Mars.
The reason I like to follow the Sea Level Ruse 🙂 issue is that we will know precisely in a few decades how wrong all these forecasts have been. With temperatures, regardless of how flat or downward the trends are, the comeback will always be that had it not been for negative forcings, the temperatures would have gone up more. The debate of AGW will go on for generations due to the difficulty to falsify either way. By 1930, the trends in SLR will be either accelerating or not and we will have observable proof.

Leif ,I am simply going by present and past data which has brought me to the conclusions I have come up with.
Yes I will admit to being wrong if solar activity approaches my solar parameters and the global temperature trend does not decline.
Many agree more or less with what I say, while many others (as you do) do not agree.
That is fine, because every single aspect of this subject of How The Climate May Change is in dispute.
There is no agreement, and given that only future data and time will tell who is most correct.
My approach has changed in that I am going to rely on data and not turn to theories to try to find out How The Climate May Change.
You could be correct, I could be wrong only time will tell. As of now none of us really know for if we did these discussions would not be occurring on an ongoing basis.
The very big problem with your theory is how do you reconcile abrupt climate changes which have taken place countless times in the past with this explanation?

The sun does have an influence on the climate, but it is minor. CO2 does have an influence too, but also minor [with the amounts we are putting out]. Internal fluctuations [e.g. of ocean circulation] may be the causes for changes on the scale of decades or centuries, while changes in the Earth’s orbit [mainly caused by Jupiter] are the cause of glaciations. Over billions of years, the Sun eventually becomes the dominant cause, but we don’t need to worry about that for now.

Leif ,how do you reconcile your thoughts with the data which shows climatic change takes place over very short periods of time of perhaps decades or even less?
Obviously they adjusted their predictions when the volcanic eruptions occurred. Not very accurately as was pointed out. But what did the original prediction look like from 1979 before they made their adjustments? We could see how far off they really are!
The problem is volcanic activity can be tied to solar activity so they are wrong again.
The Ghost Of Big Jim Cooley,
It is futile to mix philosophy of science discussion with theology discussion, unless the discussion is strictly within the context of demarcating which has a metaphysics and epistemology that is objectively demonstrable; objectively demonstrable via independently corroborated (from manifold sources with widely diverse independency) observations of reality / nature.
Science has no basis in theology. The evidence forming the basis of that statement is that scientists can be simply total naturalists (theologians inaccurately calls them ‘aethesists’) or they can be simply total supernaturalists (divine being believers) or they can have random (even contratdictory) thoughts at a whim in the matter (such as some philosophical pragmatists). My conclusion has consistently been (during 40+ years of discussions with theologians) that religion (& theology) has no fundamental irrelevancy to any scientific epistemology process or any scientific metaphysics process.
Take care.
John
Yeah, ok John! If I can be of help to you; try writing more clearly. No one wants to search for the subtext. As an 1-minute essay, read my piece (that you quote), then read yours. I had to read yours twice – people on net forums shouldn’t have to do that. If is not an exercise in futilty to mix ‘science’ with religious belief within a discussion. One is the best explanation we have, based on hypothesis, experimentation and results, the other is simply a human construct that is full of logical contradiction, and one that offers an explanation that is not provable or testable.
Big Jim,
Even if you are correct, there is no need to rub it in.

The Ghost Of Big Jim Cooley,
It is futile discussion as I said unless it is a demarcation of what is science and what is not science. Serious hard physical science dialogs consider theology irrelevant. Don’t you think so?
As to everyone’s view of writing styles and other’s likes and dislikes no comment. Although I wish everyone had access to an editorial board service before posting their comments. I do mean everyone.

Science is not Opinions. Pseudo science and wishful thinking are.
Who is wishing ? I am simply going by the data which does not support the assertions that solar/climate relationships do not exist.
I have yet to see data that counters this.
You may not agree and that is fine. This is why these discussions are presently going on because of the different take different people have on the data and the cause of why /how the climate may change.
You can not convince me that I am wrong and I can not convince you that I am correct.
This is how it is and will be until future data decides the verdict.
There are no data supporting what you claim. There are many claims and counter-claims, but none of them are convincing.
And i’m really interesting in convincing you about anything. True believers in a cause cannot be convinced otherwise. And it is not worth even trying. It is worth, though, pointing out that their so-called data and evidence do not hold up.
not interested, of course
Contrary there is much data supporting my claims.
Why argue again we are both set in our beliefs. Time will tell, this is why presently there are two schools of thought.
on the contrary, I’m perfectly willing to change my position when the data compels me to do so.
In fact I have done so in the past.
I’m partly credited with reviving the Sun/Weather/Climate field back in the 1970s. Here is one my most famous papers [cited 116 times and still cited today]:
https://scholar.google.com/citations?view_op=view_citation&hl=en&user=qFdb2fIAAAAJ&pagesize=100&citation_for_view=qFdb2fIAAAAJ:zYLM7Y9cAGgC
Solar magnetic sector structure: relation to circulation of the earth’s atmosphere
John M Wilcox, Philip H Scherrer, Leif Svalgaard, Walter Orr Roberts, Roger H Olson
1973/4/13, Science, Volume 180, Issue 4082, Pages 185-186
Abstract The solar magnetic sector structure appears to be related to the average area of high positive vorticity centers (low-pressure troughs) observed during winter in the Northern Hemisphere at the 300-millibar level. The average area of high vorticity decreases (low-pressure troughs become less intense) during a few days near the times at which sector boundaries are carried past the earth by the solar wind. The amplitude of the effect is about 10 percent.
Unfortunately, subsequent data showed that the effect was spurious. But there are still serious researchers [e.g. Brian Tinsley, http://en.wikipedia.org/wiki/Brian_Tinsley ] believing in the effect.
There is plenty of data that demonstrates no correlation. That demonstration, with links, has occurred countless times by several on this blog.
That is your opinion not the opinion of mine and many others.
Pamela I say who cares you have your opinion I have mine.
Go with what you believe in and maybe you will be proven correct ,maybe not.
The world is already cooling. In 15 years the effects will be distinct. Maybe then they will realise.
I do not see cooling in atmospheric temperatures (what regional or global temperature data set do you see a downward trend???). However, since the equatorial band easterly trade winds have calmed down to the point that the doldrums have set in and warm water has sloshed eastward and risen to the top, I will say that simple physics tells me that the oceans are dumping stored heat into the atmosphere, meaning they are losing heat. This heat rises and is eventually lost through the atmospheric layers and out to space. But this is not happening to the degree that the atmosphere is cooling down. It appears to be rather stable after 1998.
Pamela,
RSS shows global cooling since at least 1997:
But you could call it stable. So far.
However solar activity and oceanic circulations appear to be setting up another multidecadal cooling cycle, as from the 1940s to late ’70s.
I am beyond getting into arguments with individuals over this topic it is not worth my time or effort and besides it will only be in vain.
It is not worth our time to be repeatedly carpet-bombed by your opinion piece.
Nor yours which does not explain why the climate changes.
You can not reconcile abrupt climate changes with your thinking of how the climate system works. In contrast my opinion piece offers an explanation.
You don’t want to argue with “individuals” ?
Is that a nice way of saying, idiots ?
Well you sure came to wrong place, didn’t you 🙂
“When Will Climate Scientists Say They Were Wrong?”
The third Tuesday after never.
“The first Tuesday after the first Monday after Resurrection Morn.”
–HL Mencken
Second Tuesday of next week.
I wonder about how the alignment at 1979 in the diagram was done, and the baseline that was used to calculate the anomalies. Might see if I can find the original. Either way, it is probably not peer-reviewed.
Very few, if any, climate “scientists” will ever admit that they were wrong. What is more likely is that some people will wake up one morning, and the thought will occur to them that they haven’t heard anything about (what was it called?) ah yes, “climate change” for several years.
How many models were there in 1979? One? Two? And, they would have adjusted for the volcanic eruptions…not predicted them.
So, the accuracy pre-1995 isn’t so much accuracy as it is hind-casting.
