I was trawling the internet and came across another failed prediction from WUWT. This one was from Girma Orssengo, PhD, and he made his prediction in 2011 (archived here). Even though his prediction was only four years ago, and even though it was projecting ahead to 2030, I think it's fair to say that it's not looking too hot.
|Girma's pendulum, from Wikipedia via WUWT|
I should say, it is looking too hot for Girma Orssengo, PhD. I predict his prediction will fail. Any takers in a bet?
As is common with articles at WUWT, the article is quite a mess and the diagrams aren't pretty. What Girma was postulating was that the global surface temperature acts like a pendulum. He even posted a picture, in case any WUWT readers didn't know what a pendulum is.
Girma started off quoting Richard Feynmann, which at WUWT is a dead giveaway that he's a science denier. Then, after whining that it wasn't fair to blame poor innocent CO2 for warming (bizarre was a word he used), Girma wrote:
In this article, following Feynman’s advice, an alternative interpretation of the same GMT data is provided that throws doubt on the accelerated warming interpretation of the IPCC.
This alternative interpretation was also used to estimate the GMT trend for the next two decades, which shows global cooling from the GMT peak value of about 0.45 deg C for the 2000s to 0.13 deg C by the 2030s.He explained:
This alternative interpretation demonstrates that the current 30-years warming is just a warming phase of a 60-years cooling and warming cycle. As a result, we should not panic with “widespread melting of snow and ice, and rising global average sea level” because that is what happens during the warming phase of the globe, and the snow and ice will form again during the cooling phase of the globe in the next two decades.
The mythical 60 year cycle
Girma put up a chart to show what he meant by his 60 year cycle. It's not exactly 60 years. The first cycle was 65 years and the second was 53. His chart goes to 2010 (he wrote the article in 2011). I've overlayed his chart with the actual surface temperature from 1880 to 2015, using HadCRUT4. He would have been using HadCRUT3.
|Figure 1 | Girma's model from WUWT, with my annotations.|
Anyway, you get the idea. He saw a pattern of ups and downs in the long term warming trend. He saw that there was an upper limit and a lower limit to the trend. Girma figured the surface temperature would continue in this pattern. He thought once it hit the upper trend line the temperature would drop toward the lower. It hasn't. Or not so far. Instead it's broken out of his boundary lines.
There's more. On the strength of this, Girma made a prediction looking ahead to 2030. Below is Girma's prediction as illustrated in his chart.
|Figure 2 | Girma's model from WUWT, extrapolated with his prediction.|
Like I said, it's messy and a bit hard to follow. If you look to the right you'll see he has put in what he calls the IPCC's prediction, and down the bottom he's put what he calls the Skeptics Prediction. The straight red line is what he regards as the top boundary from Figure 1 above. The green line at the bottom is the bottom boundary line from Figure 1 above. The middle straight black line is the long term trend, which he said was 0.06 C/decade (from 1880 to 2010). Girma explains:
Figure 2 shows that the upper and lower GMT boundary lines are parallel to the long-term global warming trend line for the whole data from 1880 to 2010, which has a global warming rate of 0.06 deg C per decade.Girma continues (my paras):
The most important observation in this article is that the upper GMT [global mean temperature] boundary line passes through all the GMT peaks, the lower GMT boundary line passes through all the GMT valleys, and these lines are parallel. It was also found that the line that bisects the vertical space between the two GMT boundary lines is nearly identical to the long-term global warming trend line of 0.06 deg C per decade for the whole data.
This result indicates that, for the last 130 years, the GMT behaved like a stable pendulum with the two GMT boundary lines that are 0.5 deg C apart as the end points of the pendulum’s swings, and the long-term global warming trend line of 0.06 deg C per decade as the pendulum’s neutral position.
Global warming scares Girma
Girma decides something about some "climate tipping point". I don't know what he's referring to there. In any case, I think he's arguing that the greenhouse effect is "science fiction" made up just to scare him and anyone else who has an over-active amygdala. He wrote:
As a pendulum with a constant swing does not have a “tipping point”, the claim of a climate tipping point is a science fiction, made by those who unfortunately make their living by scare mongering.
The failed fake sceptic prediction
I've done something similar to his second chart. I've overlayed the actual temperature from HadCRUT4.
|Figure 3 | Girma's model from WUWT, extrapolated with his prediction, with my annotations and additions.|
As you can see, the temperature hasn't just misbehaved and not swung back down as a pendulum should, it's shot up above Girma's impression of the IPCC's upper level prediction.
An answer to Girma's question - better four year's late than never
Girma posed a question to climate scientists:
Here is a question to climate scientists: In Figure 2, why has the GMT touched its upper boundary line only 3-times, every 60-years, but has never crossed it for long in the last 130 years?That's not hard to answer. If he'd positioned his upper line lower, the temperature would have broken through twice in his chart. Look at the chart below and you'll see what I mean. If instead of choosing the orange dotted lines as his boundaries, he'd instead chosen the purple dotted lines, the temperature anomaly would have busted through. As it is, it's broken through his upper boundary now.
|Figure 4 | HadCrut data with lines like Girma's, and shifted.|
Girma wrote about cherry-picking but didn't understand what is meant. He indulged in a bit of cherry-picking himself. He thought it meant this:
Anthropogenic global warming advocates always accuse skeptics of cherry picking. A working definition of a cherry picker is one who makes conclusions based on comparison of oranges to apples. Let us see who is the greatest cherry picker.That's not it. Cherry picking is picking out the bits that you think support your argument and ignoring the bits that don't. I'd say that Girma became horticulturally lost.
How Girma found an un-named, un-sourced temperature reconstruction of the Holocene, way back in 2011
Girma also wrongly claimed that his cycles could be traced all the way back to the holocene climatic optimum, at least 8,000 years, writing:
In Figure 2, although the upper GMT boundary curve is a straight line for the relatively short 130 years data, in a longer time scale, it is part of a very long curve that contains the Little Ice Age, Medieval Climatic Optimum, Holocene Maximum, etc.He wrote that two years before Marcott13 and PAGES 2k. Your guess is as good as mine about where he got his surface temperature reconstruction for the entire Holocene, especially one that claimed a good resolution on annual timescales.
Why Girma left out the first 30 years of data
That claim plus his cherry-picking comment brings me to another major flaw in his reasoning. You may have noticed that although he used HadCRUT for his temperature data source, he started his charts in 1880. I'll show you why he did that:
|Figure 5 | HadCrut data going back to 1850, with lines like Girma's.|
If he'd added in the previous years, his upper and lower boundary lines wouldn't fit. However in the comments he linked to a chart that he seems to think works, though he had to change his boundary lines for it to do so. Not only does his new chart pop out of the boundaries more often, it mucks up his claimed 60 year cycles.
Girma Orssengo, the accelerating conspiracy theorist
There is quite a bit wrong in Girma's article. The main thing wrong is that he assumes that global warming is a hoax. He doesn't think that warming has accelerated, and uses the word something like 18 times in his article. He wrote:
A valid example of identifying whether the GMT data shows accelerated warming is to compare the change in GMT during the recent warming period from 1970 to 2000 with the previous warming period from 1910 to 1940, which are of the same duration. As shown in Figure 2, for both periods the change in GMT is about 0.68 deg C. As a result, there is no acceleration in the recent warming period compared to the previous one.
It looks as if he just eyeballed the difference in surface temperature rather than actually working out the trend. Using HadCRUT4 the trend for the latter period is higher at 0.166 C/decade, while the trend for the former is 0.134 C/decade. (The trend from 1970 to 2015 higher still at 0.169 C/decade).
|Figure 6 | HadCrut data with linear trends for 1910-1940 and 1970-2000.|
In any case, by picking out one period and ignoring the bits in between is no way to see if the warming has accelerated. (I mentioned the change point analysis in the last article I wrote.)
Girma finished by saying once more that he thinks climate science is a hoax, writing:
In the next two decades, if the GMT swings from its current peak towards its neutral position and then reaches the lower GMT boundary line to a value of about +0.13 deg C in the 2030s as shown in Figure 3, the whole world will agree with the late Professor Harold Lewis’s characterization of anthropogenic global warming:
"It is the greatest and most successful pseudoscientific fraud I have seen in my long life as a physicist.” 
In my case, I will replace the word “physicist” with “engineer”.
I've written about Girma's nonsense on a previous occasion, but I haven't seen him around lately. I wonder is he revising his conspiracy theory in recursive fashion to take account of the recent hottest years?
From the WUWT comments
This blast from the past is an opportunity to see if WUWT fans have changed in the past four years. There were more of them commenting back in the old days. Other than that, not much has changed except the nutters used to get a bit more pushback from pro-science types.
David, UK wrote an "I don't understand it but it's brilliant" thought:
August 19, 2011 at 5:23 pm
Brilliantly put. So, come on Alarmists: knock this down. Give it your best shot.
Ursus Augustus did the same:
August 19, 2011 at 5:56 pm
Thankyou Dr Orssengo. Another brick in the wall.
So did wayne Job
August 19, 2011 at 6:08 pm
Unprecedented in its simplicity, and irrefutable in its conclusion. Brilliant.
polistra could be right. I can't think of much more bizarre and tragic lunacy than there's been at WUWT over the years, at least when it comes to climate crackpottery:
August 19, 2011 at 6:13 pm
If we have descendants, they will look on the late 20th century and early 21st as a bizarre and tragic time of utter lunacy, when almost every branch of science ferociously pursued blatantly obvious lies and instantly disprovable nonsensical theories, abandoning all previous clear understandings.
Only biology and geology have been comparatively exempt from the mass hysteria.
This 33/66 cycle was well known in the ’30s, as I’ve pointed out here at least 33 times. Maybe 66 times!
John Brookes is puzzled by Girma's article:
August 19, 2011 at 7:30 pm
What sort of analysis is this? It is truly weird to fit a model with no justification and expect it to be in any way related to reality.
Roger Sowell is a conspiracy theorising lawyer who is scared of his own shadow. He'd find it hard presenting a case in any court:
August 19, 2011 at 8:01 pm
Dr. Orssengo, this is a very good, cogent analysis. Major compliments for a clear explanation with excellent graphics. I also like your initial caveat, “. . . the same data used by the IPCC from the Climate Research Unit at the University of East Anglia was used, and it was assumed to be valid.”
That brings me to my point, assuming the data are valid. We know that the data were adjusted and manipulated to show lower values in roughly pre-1970 and warmer values post-1970. In essence, the data were manipulated to impart a slight positive trend. That alone likely accounts for the increase of 0.06 degrees Centigrade per decade. Without that deliberate adjustment, the data would likely show zero warming at all. The un-adjusted data could very well show a cooling trend, which would coincide with the evidence now before us all.
This was before Anthony Watts banned the ever-polite R. Gates for being too sciency:
August 19, 2011 at 8:28 pm
RoHa says: August 19, 2011 at 6:47 pm "So the temperature is going to start dropping to Little Ice Age levels again?
Even with a Maunder type minimum, the earth of 2011 far different in atmospheric composition than the earth of the 1600’s. A new “little age age” is quite unlikely.
Mike Jowsey sees slightly different cycles, and thinks that it will cool after 2013. Didn't happen.
August 19, 2011 at 9:40 pm
August 19, 2011 at 6:13 pm
This 33/66 cycle was well known in the ’30s
Looking at Figure 2 it seems that a 33/66 cycle would be a more accurate pendulum swing. It would not change the 0.06dC per decade trend. It would, however, have the second cycle in the dataset ending in 2012 rather than 2000. This would also indicate that the next cooling phase is 2013 through 2036.
Interstellar Bill is going to hold R. Gates to his idea that a Little Ice Age isn't coming any time soon. So far R. Gates has the upper hand.
August 19, 2011 at 9:49 pm
Usually the Warmistas are reluctant to give us
any falsification criteria for their AGW doom-scenarios
(which are notoriously replete with every kind of bad outcome).
They’re usually quick to cite this or that meteorological event
as bolstering their case, but reluctant to accept anything as weighing against it.
But the esteemed R. Gates just declared
that a new Little Ice Age is quite unlikely.
Finally, something that disproves AGW!
We’ll hold you to it.
I can think of another one, though: CO2 levelling off.
Bill H sees a sine wave. Does that remind you of anyone?
August 19, 2011 at 9:59 pm (excerpt)
the positive slope in the 60 year cycle is the long term warming that has been occurring since the last ice age. what i am finding in my studies is rather simple. the earth and its systems are all in a phase of sign wave. if we extrapolate the graph out to several thousand to hundred thousand years you would find a sign wave or oscillation of the warmth/cooling trends.
Alexander Feht flings wild accusations of fakery. Another climate hoax conspiracy theorist.
August 20, 2011 at 12:07 am
And this is assuming that known fakers’ data hasn’t been faked by the fakers!
Alarmists have painted themselves into the corner.
Girma had the almost last word, saying something about nature exposing them. It's exposed Girma, hasn't it.
August 22, 2011 at 2:39 pm
The truth finally wins.
They have completely ignored the cyclic nature of global mean temperature, and it is just a matter of time that nature will expose them.
