When Will Climate Scientists Say They Were Wrong?

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.

michaels-102-ipcc-models-vs-realityThe 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.

Solar cycle changes is the cause of the majority of the warming in the last 30 years.
Any idiot knows, the mechanism causes that changes to the earth’s temperature is not a change to the solar total irradiation.
Only an idiot would continue to provide a link to a graph of total solar irradiance (TSI) stating that solar changes are not causing the planet to cyclically warm and cool. What is the point?
I can and will now defend the assertion that solar cycle changes are the reason for the majority of the past warming. We are now going to experience scary abrupt cooling. This is no longer a game, we have a front row seat to watch the most important solar event in recorded history and the most important climate change event in recorded history.
TSI changes are small. If TSI changes was the cause of the warming the majority of the warming would be at the equator not in high latitude regions, as the majority of the short wave solar radiation is received and the majority of the long wave radiation is emitted in the equatorial regions. The same logical argument applies for greenhouse gas warming. The majority of the greenhouse gas warming should be at the equator. There is almost no warming at the equator which supports the assertion the warming has not caused by the increase in atmospheric CO2.

The majority of the warming has been in high latitude regions which supports the assertion that something that cause latitude specific warming is the cause.
The solar changes cause planetary warming by modulating the amount of cloud cover and cloud properties. There are cycles of high latitude warming and cooling that correlate to solar magnetic cycle changes.
The solar magnetic cycle has been interrupted. The high latitude regions have started to cool.

IMO the UV component of TSI, which varies much more than TSI, is an important influence on climate, as is solar magnetic flux.

Sigh. How much energy is in UV and magnetic flux? Since you say these things have important influences on climate, you will undoubtedly need to propose amplifiers. Funny how we never get to read the details about those amplifiers from solar enthusiasts. And links to peer-reviewed high quality research are nonsupportive. So what we get are links to marginal peer-reviewed low quality research. Of course if one is not schooled in standard research critique methods, solar supporters blithely pay-it-forward, echoing this nonsense to others easily convinced of piecrust theories. Easily made, easily broken.

What would be the point of showing you the abundant support for hypotheses arguing the varied effects of UV and magnetic flux on climatic phenomena?
You must have seen them before to have concluded that they’re rubbish.
Trying to lead true believers to valid science at odds with their religious faith is generally a waste of time.

Reply to  yankwanker

Pamela,
The amplifiers are the repeatedly demonstrated mechanisms by which variation in UV and solar magnetic field strength have been observed to affect climatic phenomena.
Why you chose to ignore so much actual data, ie direct observations of nature and experimental results, is mysterious to me. In the case of UV the observed mechanisms include but are not limited to the effect on ozone levels and absorption of the increased energy in seawater and, arguably terrestrial surfaces as well.
To ignore reality is as anti-scientific as it gets.

Reply to  sturgishooper
May 31, 2015 9:45 pm

An even greater sin is to confuse wishful thinking with reality. The energy in the UV and in the solar magnetic field is minuscule and the heating effect on the troposphere is negligible. The upper atmosphere is severely influenced, but that is because the density there is a billion times smaller than at the surface.

Reply to  yankwanker
May 31, 2015 9:55 pm

Lief,
Small doesn’t mean insignificant.
Since the effect of UV variation on the upper atmosphere is indeed severe, the effect on climate of that flux on climatic phenomena is similarly important.
As you know, in physics effects often don’t scale linearly, in both directions, ie greater and lesser. Take for example the effect of increasing energy in nuclear detonations with their blast, radiation and thermal effects on the ground and air.
Mechanisms by which UV (to say nothing of magnetic flux) can and does affect climatic phenomena have not only been proposed but conclusively demonstrated in the field and the lab.
Thus, to dismiss out of hand the possibility of important effects of solar activity on climate seems to me, as I said, not only unscientific but anti-scientific, and example of hand-waving special pleading of heroic proportions. In short, the reaction of a true believer.

You cannot so conclude. Just because A is big does not imply that B is similarly big. When you compare the energetics that should be blindingly obvious, but as you say, one can never convince a true believer that his view is false.

Leif,
It’s not the instantaneous energy that matters, but the time integral of the difference between high UV periods and low UV periods that matters, and the effects thereof on specific climatic phenomena.
I don’t have “belief” in any hypothesis. I just go where the evidence leads. IMO it’s preposterous to imagine that variation in solar activity doesn’t affect the climate of Earth and other planets. All available evidence tells me that it does. Which should come as no surprise.
Those who d*ny a major solar influence on cyclical “climate change” remind me of the geologists of my youth who claimed that the fit between South America and Africa was simply a coincidence and those in the 17th century who imagined that fossils just accidentally happened to resemble living things, before your compatriot Steno, a Catholic convert, conclusively demonstrated that assumption false, thanks to sharks’ teeth.

There is absolutely no evidence for that and no theory or model that explains how that would work. You are invited to come up with the detailed numerical calculations that support your claim.
For the rest of your comment: they are just the usual silly analogies that are totally irrelevant and are all simply fallacies ranging all over the map. Here is another one that you would appreciate: a stone cannot fly, you cannot fly, ergo you are a stone.

Recent cosmic ray study, finding a statistically significant effect on year-to-year temperature fluctuations of solar-modulated GCR flux. Naturally its authors had to d*ny any secular, longer term affect on climate in order to get published, but despite such obligatory genuflection toward the orthodoxy, how could the cumulative effect of decades of temperature differences not affect climate?

Reply to  sturgishooper
May 31, 2015 10:53 pm

Their conclusion:
Our results suggest weak to moderate coupling between CR and year-to-year changes of GT. They resonate with the physical and chemical evidence emerging from laboratory studies suggesting a theoretical dynamic link between galactic CR and GT. However, we find that the realized effect is modest at best, and only recoverable when the secular trend in GT is removed (by first-differencing). Thus, it is important to stress that they do not suggest that CR influences can explain global warming and should not be misinterpreted as being in conflict with the IPCC (25). Indeed, the opposite is true: we show specifically that CR cannot explain secular warming, a trend that the consensus attributes to anthropogenic forcing. Nonetheless, the results verify the presence of a nontraditional forcing in the climate system, an effect that represents another interesting piece of the puzzle in our understanding of factors influencing climate variability.

The sun can have and does have a small effect [even the 0.1% TSI variation translates to a 0.1K delta T]. The main issue is whether the sun is a major driver, and clearly as your link shows, it is not. Are you now convinced?

And, yes, if the data don’t support your belief, there must obviously be something wrong with the data…

Reply to  yankwanker

That doesn’t answer my question.
I looked for the source in the paper.
The correlation is good until near the end, when the “data” appear adjusted warmer.
As I said, although I haven’t contacted its authors, I suspect that the verbiage you cite and which I mentioned was inserted so that it could survive review.

Reply to  sturgishooper
June 1, 2015 9:44 am

Then your question was ill-posed. As for ‘surviving review’, I think it is just the opposite: they find no correlation, but in order to show the relevance of their work [and obtaining funding] it is important to claim that at least some of it seems to be climate related. I use the same trick and it works really well. Here is the last line of our press release for the upcoming IAU general assembly in August:
“This revision of the sunspot number has thus numerous implications for studies of the solar dynamo, space climate, and possibly terrestrial climate change.”

I’m amazed they’ve managed to hold off on admitting at least some error this long. I had the audacity this week to point out some errors in a Cosmos episode on global warming hosted by Neil DeGrasse Tyson. I was accused of being a mindless minion of Fox news and was bombarded with 20 You Tube Videos ‘proving’ CAGW. You Tube Videos! It’s hard to believe that anyone can still insist that this is ‘settled science’. I’ve been arguing about CAGW for almost 18 years and I have to admit…it loses some of the sport when the theory you’re arguing about is proving itself wrong with every passing year.

Reply to  Scott Saturday
May 30, 2015 2:52 am

Here’s the thing, a cooling planet doesn’t actually ruin CAGW. 18, 20, 35 years of cooling…or for that matter 18 to 50 years of warming. It doesn’t validate or ruin CAGW in any way. The original assertion that Co2 is now the main driver for global climate hinges on what happens to the heat. We know beyond doubt that Co2 and IR have a lovely relationship. What we don’t know, and this is what Lindzen and others have focused some of there time on, where does that heat go? What are the key and supporting interactions…water vapour, arisols, ocean heat transfer, solar cycles. We don’t know enough to be concrete in our assertions. As for CAGW, we may yet experience a warm glut of water that has been ruminating in the deep which will raise surface temps 2C within the next 35 years…WTF knows? Its not looking like that will happen, and every day its looking like Co2 does not drive today’s climate. To kill CAGW we have to deal with the theory, because as any zealot will tell you…the warming may yet come…which on its head will mean nothing. That’s where we’re at

May 29, 2015 1:52 pm

They do not admit being wrong because they use a different measurement of wrong.
According to the temperature data there has been a warming trend, and so they declare their models are correct since they also show a warming trend. The specifics of the warming trend are glossed over because as they say, “THERE IS A WARMING TREND, SHUT-UP ABOUT IT ALREADY.”
Yes there has been a trend, but their trend is a gross exaggeration of what actually occurred and is occurring, and they ignore the 2 decade halt in the warming trend. This is of course dishonest. Courts expect the truth the whole truth… Partial truth is considered a lie. They are using a partial truth to lie.
If the warming trend ticks up again they will claim credit for predicting it, (no matter how accurately or not) and if the trend goes towards cooling it is because they have saved the world. Taking credit for what ever happens up or down is normally the provenance of shallow politicians. That climate scientists thought this a good model, so to speak, to follow remains unfortunate.

The executive reports by the wordsmiths have gone in the exact opposite of the indicated prediction errors. That alone should tell any reasonable person that this is not science. Back to the chart, it’s going to look a lot worse when the AMO pulls the hiatus into an outright decline while the sky hook projections are going off the charts. Slope differences at the margin will be glaring and will require even more ignoring of the facts and name calling by the green cultural revolution zealots.

The models were wrong going forward, and they couldn’t get them to go back either. The LIA and MWP weren’t that long ago. To cover those events, they said it didn’t happen, it was local and not world wide. ( both events have been shown to be world wide). CAGW main evidence is the correlation between co2 and temp. If you look at the chat they drew up, do you see a change in temps during any of those times? If the temps changed, then the co2 levels would have had to change. Then they would have been left with having to explain where the co2 came from or went.

The ‘interruption of the magnetic cycle’ is what any idiot might believe, but has no grounding in fact. So your premise is wrong [or worse].

Why do you continue to make the same silly comments concerning TSI? Changes in TSI did not cause the planet to warm and is not the reason why there is sudden cooling of both poles of the planet.
What you are doing is creating a straw dog, to distract the reader from the real cause.
You have no idea what is happening to the sun and you have no idea how changes to the solar cycle affects planetary temperature.
You have ignored the fact that sunspots are shrinking and now disappearing.
You have provided no physical explanation as to why sunspots were shrinking and now disappearing. The sunspots have observationally changed. The is a physical reason for the observational change in sunspots.
You ignore observations that disprove your beliefs. Cult science is what Feynman calls people who continue to support a hypothesis that has been disproved by observations.
Do you have anything beyond name calling and repeating your old tired beliefs?
The sun modulates planetary cloud cover.
The solar cycle has been interrupted which will and has caused an increase in high latitude cloud cover which explains the sudden cooling of both poles.
What is currently happening to the sun has happened again and again and again and again and again and again and again and again … which explains how the late Gerald Bond has able to find 22 cycles all of which correlate to solar cycle changes which is the limit of the paleo proxy.
The interruption to the solar cycle is also the reason for the sudden increase in rainfall, see Little Ice Age for what to expect next in terms of the regions and type of effects, however the actual cooling be more sever, similar to the 8200 BP abrupt cooling event.

Little Ice Age
The Little Ice Age (LIA) was a period of cooling that occurred after the Medieval Warm Period (Medieval Climate Optimum).[1] While it was not a true ice age, the term was introduced into the scientific literature by François E. Matthes in 1939.[2] It has been conventionally defined as a period extending from the 16th to the 19th centuries,[3][4][5] or alternatively, from about 1350 to about 1850,[6] though climatologists and historians working with local records no longer expect to agree on either the start or end dates of this period, which varied according to local conditions ….
Europe/North America
….The population of Iceland fell by half, but this was perhaps caused by fluorosis after the eruption of the volcano Laki in 1783.[20] Iceland also suffered failures of cereal crops, and people moved away from a grain-based diet.[21] The Norse colonies in Greenland starved and vanished (by the early 15th century), as crops failed and livestock …. …. Hubert Lamb said that in many years, “snowfall was much heavier … ….Crop practices throughout Europe had to be altered to adapt to the shortened, less reliable growing season, and there were many years of dearth and famine (such as the Great Famine of 1315–1317, although this may have been before the LIA proper).[25] According to Elizabeth Ewan and Janay Nugent, “Famines in France 1693–94, Norway 1695–96 and Sweden 1696–97 claimed roughly 10% of the population of each country. In Estonia and Finland in 1696–97, losses have been estimated at a fifth and a third of the national populations, respectively.”[26] Viticulture disappeared from some northern regions. Violent storms caused serious flooding and loss of life. Some of these resulted in permanent loss of large areas of land from the Danish, German and Dutch coasts.[24]
Historian Wolfgang Behringer has linked intensive witch-hunting episodes in Europe to agricultural failures during the Little Ice Age.[36]
Antarctic
Kreutz et al. (1997) compared results from studies of West Antarctic ice cores with the Greenland Ice Sheet Project Two (GISP2) and suggested a synchronous global Little Ice Age.[46] An ocean sediment core from the eastern Bransfield Basin in the Antarctic Peninsula shows centennial events that the authors link to the Little Ice Age and Medieval Warm Period.[47] The authors note “other unexplained climatic events comparable in duration and amplitude to the LIA and MWP events also appear.”

That is exactly correct. You said it well.

Well put William, It is indeed the sun and nothing to do with TSI, the sun’s behaviour and it’s cycles are controlled by the positions of the large giant planets. It is not gravitation but the feed back of charge that enters the poles of the sun and exits approx. 30 degrees north and south in that band. This planetary positioning gives us both the length and strength of the solar cycles. It is this charge [ the missing 95% of the universe} that gives our Earth the warm periods and the ice ages. The solar system tilt to the galaxy and our positioning in or near galactic arms also play a part. CO2 does diddly squat.

as France’s top Climate Diplomat, Laurence Tubiana said at the Carbon Expo 2015 in Barcelona this week, it (CAGW) is not an ideological question, it’s an economic question. science doesn’t come into it.
Tubiana also admits to RTCC’s Ed King that French climate teams are bypassing National Govts to depoliticise the issue by working with sub-national entities – think California, Canadian provinces or the so-called “seven Australian governments” Christiana Figueres (UNFCCC) met with in Australia, as reported by the Guardian, (UN climate chief says the science is clear: there is no space for new coal – 4 May):

26 May: RTCC: Can carbon pricing be a climate saviour?
By Alex Pashley in Barcelona
The Carbon Expo is filled with carbon pricing advocates, but the concept does have its detractors.
Socialist-leaning countries like Venezuela in the ALBA negotiating bloc reject market-based mechanisms. You cannot put a price on nature, they argue, nor should businesses or nations be allowed to trade away their obligations…
Giving clearer signals to business so they can prepare is critical, adds Kyte (World Bank), and the “foundation for unlocking investment… for a innovative, dynamic low carbon economy”…

btw do a search “Carbon Expo 2015” Barcelona, and you will find the MSM is as silent about the financial shenanigans that went on there as they are about trade deals such as TPP and TTIP. even Bloomberg, a media partner along with Reuters, has said nothing. as for Reuters, they’ve written plenty but can’t bring themselves to include the words “Carbon Expo”; instead they write about a business event in Barcelona!
