Satellites show no global warming for 17 years 5 months

FLATBy Christopher Monckton of Brenchley

The monthly satellite lower-troposphere temperature anomaly from Remote Sensing Systems, Inc., is now available.

Taking the least-squares linear-regression trend on this dataset (the bright blue horizontal line through the dark blue data), there has now been no global warming – at all – for 17 years 5 months.

Would readers like to make a projection of how many mainstream media outlets will report this surely not uninteresting fact?

It shows that the Hiatus hernia for true believers in the New Religion continues.

My own prediction is that the number of media reporting 17 years 5 months without any global warming will be approximately equal to the number of general-circulation models that predicted such a long Pause notwithstanding ever-rising CO2 concentration.

Print out the graph as a postcard and send it to the editor of a newspaper near you that has shut down democratic debate by announcing that it will refuse to print any letters at all from “climate deniers”.

About the chart
Horrors! I just realized you’ve done this in the colors of the left coast team that just won the american-type football big game. Thanks, though. It downloaded fine and now resides on my hard drive.
For Kathy
The 17 year thingy: Some years ago a member of the “climate Team” expressed the view that 17 years would be indicative of a problem in the Team’s approach to modeling Earth’s atmosphere and taking its temperature.** Apparently, graduate students at several universities poured over hundreds of model runs and could find a “pause” of only about 15 years so the next logical jump was that 17 would not happen in the real world. [I can make leaps of imagination too – I don’t know what really was done in those ivory towers!]
As the 17 year pause got near, the necessary length to be a problem was reset (moving the goal posts) to 30 years or something. No one really cares about the latest statement from “the Team” because “The 17-year Pause” was stated first and boldly. It is the icon of moment and is thus the reason for titles, such as for this post, to incorporate it.
____________
**This used to be done under the arm (Stevenson screen) but the Team now thinks the appropriate place to check Earth’s temperature is in some deep hole where the Sun doesn’t shine.

To AndyL:
The answer to your question was provided by Richard Barraclough.
By using the site http://www.woodfortrees.org/plot/rss/from:1999.0/plot/rss/from:1999.0/trend
and starting the plot from the beginning of 1999, you do get a positive trend
with slope = 0.00275884 per year. As Lord Monckton points out, this is not
different from zero in a statistical sense.
An even more telling point, though, is that this slope is approximately
one full order of magnitude
smaller than the 0.2 degrees C. per
decade which the IPCC quotes as the ensemble average of all the GCM
models.
The entire proposed “AGW theory” is giving all the signs of a theory in
significant trouble: busted predictions, auxiliary hypotheses needed to
explain failures (Trenberth’s “missing heat is in the deep oceans” comes
to mind), increasingly strident outcry from adherents to the theory, claims
of being able to measure a small effect to outrageous precision, and the like.

The Great Lakes are also almost iced over. Only Lake Ontario and Lake Michigan have appreciable open water (although even this water it is 1/10 to 3/10 ice cover). Normally Lake Superior is ~40% iced over. Nothing like it in a couple of decades.

“Is that the same as saying the warmest 17 years on record have occurred in the last 17 years?”
Not if you count the archaeological record of Viking /farms/ under Greenland’s glaciers.

“Jones says: February 6, 2014 at 6:44 pm

Yes. In other words, the global temps have it a plateau, and there’s enough noise in the temp data to allow NOAA to declare that such and such a month was the warmest month in 17 years, or some such thing.

Thank you, J. P. Peterson and Taphonomic. FUN list, Tapho! Thanks for sharing. And, yes, your unabridged version of my postcard was much better. Remember, I was writing to a teen-aged girl who has a MILLION things to do… . (smile)
Gail — good point re: Taphonomic’s linked list — I was thinking along those lines, that many of those metaphors ARE enduring and used, even though their sources are obsolete. Carrying coals to Newcastle and Been through the wringer and Threw down the gauntlet.
Thus, there is hope that that most useful saying: like a broken record will survive.
#(:)) (seriously, I think it will — I asked a typical teenager about 2 years ago and he not only knew what that one meant, he used it occasionally … so, there’s hope for that one the next 80 years or so!)
Gail and Richard C. (and others) — WAY TO GO with the excellent refutations of the troll’s idiotic blatherings. Nice research, as usual, Gail (I think there ought to be a Gail (and Jimbo) Exception to those moderation rules).

AHEM!
John Hultquist! I thought you were from Washington State?!! I’m not even a big football fan and I am SO HAPPY THAT THE SEATTLE SEAHAWKS WON THE SUPERBOWL (I was born and raised about 1 hour from Seattle) that I could SCREAM!!! And I DID!!!!!!! Yeah, that Socialist Seattle is their town is, indeed, sickening, but, come on, man… that the Seahawks won the SUPERBOWL 43 to 8 is MAJORLY COOL! How can you, such a generous, kind, man (yes, your comments on WUWT have revealed that) be so calloused??? They are your “home team!”
To each his or her own. Hope all is well and you and Nancy are keeping warm over there.

I am sure the CAGW believers will say we are “cherry picking” to get this result. However, cherry picking is selecting BOTH the beginning and end point. When one of the end points is the present, that is not cherry picking. No warming in 17 years 5 months is just what it is, no warming.
The pause continues.

I think his point is that if one fits all intervals from the present backwards, the longest interval with either no warming or cooling (relative to the present) is 17.5 years. There are obviously many points one could terminate with active cooling — anytime in the 1997/1998 ENSO pulse, for example. There are also many points where one could terminate with active warming — right after this pulse in the rebound.
If you go back before this, there is warming visible all the way back to the start of the RSS record, but at the modest pace IIRC of 1C/century give or take a hair. We cannot go back beyond this with apples to apples comparison, but if one goes back to 1850 in e.g. HADCRUT4, the overall warming across the entire HADCRUT4 record is a modest 0.8C divided by 164 = 0.5C/century:
http://www.woodfortrees.org/plot/hadcrut4gl/from:1800/to:2013/plot/hadcrut4gl/trend
Note well that the straight line is not a terrible fit to this — an even better (but less significant) fit if one accounts for the (large) probable error in the graph. Note also the clearly visible double oscillation around the linear trend, with period of roughly 60 years. Note the nearly identical warming that occurred in the first and second half of the 20th century, the first half with no help from CO_2 the second half (according to the warmist dogma) with no help from nature.
The issue is not “the planet has not been visibly warming since the end of the Dalton Minimum as an extension of the Little Ice Age”. That’s almost certainly true on the basis of both thermometric data, human historical report, and various proxy data, nobody serious contests that although as I like to point out how MUCH warming has occurred is highly uncertain because all global thermal estimates have a substantially increasing error bar (lack of precision) as one goes back in time, never displayed on any graph (wood4trees CAN’T display it — the data isn’t there AFAICT). The real question is: “Can all or any specific part of the warming at any point on this graph be reliably and quantitatively attributed to CO_2 increases in the atmosphere”.
The answer is a very simple “no”. This, too, really isn’t a matter of discussion. The sole basis for attributing any portion of the warming to CO_2 are GCMs fit to the time that CO_2 was increasing with the prior assumption that it was the primary cause of the warming observed in the latter half of the 20th century, ignoring the fact that the warming there precisely matched that in the first half without the help of CO_2 at all. Aside from the fact that this makes the model predictions self-fullfilling prophecy across the training interval, one cannot validate any predictive model with the training data, and I have yet to see any evidence that a GCM could predict even the 164 year span of HADCRUT4 based on the parameters that fit 1970-2000 or thereabouts. And as we all know, most of the GCMs in CMIP5 (if I have the acronym letters right, sigh) are in bad disagreement with the entire interval of temperatures after their initialization, producing as much as 0.6C entirely spurious warming by the present compared to the flat temperatures observed over the entire interval.
So “the pause” isn’t about any sort of disproof of AGW, GW, CAGW, CC, ACC, CACC. It is all about the models. Our sole basis for believing any or all of the claims for continuing anthropogenic warming and possible consequent catastrophe is the predictions of the GCMs. The GCMs are not validated theories with known predictive skill, they are themselves complex highly complex hypotheses of no use whatsoever until they have been validated. Many of them are actively failing their validation — indeed, one would be tempted to say that a fair number of them (all the ones that result in absurdly high climate sensitivity) have failed their validation.
I honestly don’t think that most of the climate scientists out there do not know and understand this. They just don’t know exactly what to do about it, besides cross their fingers and pray for a massive super-ENSO that pops global temperatures back up to somewhere NEAR their extrapolations instead of steadily evolving flat to slightly falling out of the entire range predicted by all of them. Odd as it is for any human to hope that we are facing a possible disaster, because the alternative is for them to (very minimally) “lose face”. But that’s what the world has come to. One can hear actual satisfaction oozing from the voices of those that interpret every extreme event as proof that we are en route to catastrophe.
Everybody knows that if you sin against God (oops, I mean “nature”) you will be punished, afflicted with diseases, poverty, and misery (oops, I mean drought, floods from rising seas, superstorms, scorching heat) and cast into an eternity (oops, thousands of years) of hell in Hell (oops, on Earth in the form of a “changed” climate). Preachers of both sects take great pleasure in delivering sermons transforming every bad thing that ever happens into proof that God/Nature is watching you and it all is your Just Desserts. Or was that Just Deserts. I get confused.
Religion masquerading as science as a very bad thing. Science masquerading as a religion might actual be worse, though.

Monkton-
I disagree with one thing you assert:
“The “Idiot” need do no more than attend Statistics 101, as I did, and then obtain the RSS data from the link plainly shown on the graph, and then plot the data and determine and position the least-squares linear-regression trend line”
Taking a Statistics 101 course does not guarantee subsequent proficiency. There’s a good chance that Mr. Idiot would still get the statistics horribly wrong.

February 7, 2014 12:11 pm

I’m afraid I don’t quite understand this:
Sure enough, in the 8 years 9 months from 1 January 2001 to 30 September 2009 (my speech was on 14 October) the RSS dataset shows a statistically-significant cooling of 0.16 K, equivalent to 1.87 K/century of cooling.
The “Idiot” also says I said in that same speech that all global warming had stopped since 1995. And so it had – all but a statistically-insignificant 0.4 K warming over the period from January 1995 to September 2009.

Why is 0.16K/45 months (0.0035/month or 0.43/decade) statistically significant but 0.4K/117 months (0.0034/month or 0.41/decade) statistically insignificant?

February 7, 2014 12:16 pm

no temperature trend is highly unusual. Obviously an example of weather weirding and climate disruption. We are destroying nature’s cycles. Just sayin’.

Matt G
February 7, 2014 12:27 pm

The last time there was no temperature trend comparable to this length was during the previous negative PDO phase. At the time though global temperatures were showing a lot more cooling than the same data does nowadays with land surface temperatures.
The period is almost approaching the same length of time that all the global warming scare was based on.

Thank you for using your valuable time in answering my few obvious, logical observations. Satisfying to know that my comments touched a nerve, and I hope others have noted how easy it is to prod at your house of cards.
“unless it is paid very well by those who spend so much time and money trying to discredit anyone who does not unquestioningly accept every daft tenet of the New Religion – would be better off going to play in the Little Leagues in future”
No, I’m just a part-time warehouse worker, but a clever smear nevertheless. I hope to be hanging around because someone will be needed to announce to the Village that “The Lord is wearing no clothes” when global temperatures again begin to ratchet upwards.

17 years and 5 months is an odd interval. What does the data show about warming over 20 years, 15 or 30?

Ok, if I look briefly at the picture of the graph above I see: “No Global Warming For 17 Years 5 Month”. But if I look closer I see: “RSS global mean temperature change […]” and the blue line showing: 0.24 C. To me that means that there is an average temperature increase but no acceleration of the trend. Doesn’t that mean that the statement ” No Global Warming For 17 Years 5 Month” is incorrect???

Stan Williams
February 7, 2014 1:26 pm

I have a simple question. I think. Doesn’t this 17 year, 5 months hiatus in warming (assuming that satellite temperature data is the best we can get) falsify the greenhouse gas theory with respect to CO2? Warming has “paused ” and atmospheric CO2 concentrations continue to rise un abated. There appears to be no cause and effect. Isn’t this true?

“The “Idiot” need do no more than attend Statistics 101, as I did, and then obtain the RSS data from the link plainly shown on the graph, and then plot the data and determine and position the least-squares linear-regression trend line”
Or use wood4trees and do the same thing with no knowledge of statistics whatsoever, with five mouse clicks, free, online:
http://www.woodfortrees.org/plot/rss/plot/rss/trend
It takes a bit longer if you want to find the longest interval for which the curve is flat, and W4T doesn’t do a good job of telling you what the “trend” it fits is or what its e.g. chisq might be estimated to be or what Rsq is or…
But these days lots of tools will do it for you — R, most notably — for free and without needing a lot of stats mojo.

Titles and honorifics are not anachronisms, or rare; neither are they in some/any way inappropriate, or useless.
We continue to instill their use in children, at public school, where Teachers are normally addressed & referenced with various combinations of titles and/or honorifics. The head teacher running the local schoolhouse, is always “The Principle” (etc).
Police Officers, medical Doctors and Nurses, Judges, Elected Officials and lots of others, are “typically” addressed/referenced, using special terms.
In perfect truth, walking up & down the aisles of my local supermarkets, one hears staff & customers in all combinations speaking & referring to each other using “Sir”, “Ma’am”, and others – not “universally” and always, no – but rather routinely & commonly – yes.
Not only do we still use Titles for ‘higher-ups’ … our organic culture at the grass roots keeps honorific forms of address entirely & pragmatically relevant, among & between the ordinary citizens.
Whatever could you have been thinking …, Sir?

Warming has “paused ” and atmospheric CO2 concentrations continue to rise un abated. There appears to be no cause and effect. Isn’t this true?
I doubt that this is fairly true. First of all, one is never going to falsify the GHG theory because it is correct, and everybody who understands basic physics knows it. Furthermore, there is plenty of direct evidence of it in operation here and elsewhere we can observe including laboratory scale experiments. It really is beyond reasonable doubt. What is dubious are the claims of catastrophic warming due to additional CO_2, since the greenhouse effect due to CO_2 is long since saturated and increases in greenhouse trapping with CO_2 partial pressure are at the very best extremely weak, and at worst are largely cancelled or obscured by much larger natural effects or internal feedbacks.
What one can reasonably say is that the last 17 years are not strong evidence in favor of the hypothesis of catastrophic warming. What one can also very reasonably do is falsify specific general circulation models as being very probably wrong. One cannot falsify “GCM”s as a category, as there may well be GCMs that are good predictors of the future climate, but at this point I personally think that the hottest running GCMs with egregious climate sensitivity are just plain wrong, and a whole lot more of them are in a position of serious doubt. In the real world, falsification isn’t a matter of reaching some threshold p-value, but a gradual process where people come to doubt a result long before the p-value passes (say) 0.05 and where even a model with a p-value of 0.01 (badly failed) has a 1/100 chance of coming back from the dead and being right after all. That’s why I say “not strong evidence for” — which isn’t exactly the same thing as “direct evidence against”. Whether or not they are or are not “false”, if the damn things aren’t working there is little reason to take them trillion-dollar investment for the salvation of humanity seriously.
