Richard Kerr (Science) in 2009: Warming ‘Pause’ About to Be Replaced by ‘Jolt’
Guest essay by Robert Bradley Jr.
“Pauses as long as 15 years are rare in the simulations, and ‘we expect that [real-world] warming will resume in the next few years,’ the Hadley Centre group writes…. Researchers … agree that no sort of natural variability can hold off greenhouse warming much longer.”
– Richard Kerr, Science (2009)
That’s Richard A. Kerr, the longtime, award-winning climate-change scribe for Science magazine, the flagship publication of the American Association for the Advancement of Science. The article, “What Happened to Global Warming? Scientists Say Just Wait a Bit,” was published October 1, 2009.
The article is important in the history of climate thought because it captures neatly the (over)confidence of the scientists who turn to models to justify their faith that past overestimation will soon be reversed. Judith Curry’s recent discovery of F. A. Hayek’s Nobel Prize Lecture in Economics, The Pretense of Knowledge, marks a new front in the mainstream climate debate. [1]
Secondly, today’s explanation for the “pause” (a term used in Kerr’s 2009 article) is not mentioned back then—ocean delay.
Third, Kerr frames the debate in political terms with Copenhagen just ahead—and fails to interview or include the contrary views about how climate sensitivity might be less than the climate models assume in their physical equations.
Here is the guts of the Kerr article as the 5th year anniversary comes this year:
The blogosphere has been having a field day with global warming’s apparent decade-long stagnation. Negotiators are working toward an international global warming agreement to be signed in Copenhagen in December, yet there hasn’t been any warming for a decade. What’s the point, bloggers ask?
Climate researchers are beginning to answer back in their preferred venue, the peer-reviewed literature. The pause in warming is real enough, but it’s just temporary, they argue from their analyses.
A natural swing in climate to the cool side has been holding greenhouse warming back, and such swings don’t last forever. “In the end, global warming will prevail,” says climate scientist Gavin
Schmidt of NASA’s Goddard Institute for Space Studies (GISS) in New York City.
The latest response from the climate community comes in State of the Climate in 2008, a special supplement to the current (August) issue of the Bulletin of the American Meteorological Society. Climate researcher Jeff Knight and eight colleagues at the Met Office Hadley Centre in Exeter, U.K., first establish that—at least in one leading temperature record—greenhouse warming has been stopped in its tracks for the past 10 years.
In the HadCRUT3 temperature record, the world warmed by 0.07°C±0.07°C from 1999 through 2008, not the 0.20°C expected by the Intergovernmental Panel on Climate Change. Corrected for the natural temperature effects of El Niño and its sister climate event La Niña, the decade’s trend is a perfectly flat 0.00°C.
So contrarian bloggers are right: There’s been no increase in greenhouse warming lately. That result came as no surprise to
Knight and his colleagues or, for that matter, to most climate scientists. But the Hadley Centre group took the next step, using climate modeling to try to quantify how unusual a 10-year warming pause might be.
In 10 modeling runs of 21st century climate totaling 700 years worth of simulation, long-term warming proceeded about as expected: 2.0°C by the end of the century. But along the way in the 700 years of simulation, about 17 separate 10-year intervals had temperature trends resembling that of the past decade—that is, more or less flat.
From this result, the group concludes that the model can reproduce natural jostlings of the climate system—perhaps a shift in heat-carrying ocean currents—that can cool the world and hold off greenhouse warming for a decade. But natural climate variability in the model has its limits. Pauses as long as 15 years are rare in the simulations, and “we expect that [real-world] warming will resume in the next few years,” the Hadley Centre group writes.
And that resumption could come as a bit of a jolt, says Adam Scaife of the group, as the temperature catches up with the greenhouse gases added during the pause.
Pinning the pause on natural variability makes sense to most researchers. “That goes without saying,” writes climate researcher Stefan Rahmstorf of Potsdam Institute for Climate Impact Research in Germany by e-mail. “We’ve made [that point] several times on RealClimate,” a blog.
Solar physicist Judith Lean of the Naval Research Laboratory in Washington, D.C., and climate modeler David Rind of GISS reached the same conclusion in a peer-reviewed 15 August paper in Geophysical Research Letters. They broke down recent temperature variation into components attributable to greenhouse gases, pollutant aerosols, volcanic aerosols, El Niño/La Niña, and solar variability.
Combined, those influences explain all of the observed variability, by Lean and Rind’s accounting. But unlike the Hadley Centre’s model-based analysis, this assessment attributes a good deal of climate variability to variability in solar activity. That’s because most models can’t translate solar variability into climate variability the way the actual climate system can (Science, 28 August, p. 1058), Rind says.
Researchers may differ about exactly what’s behind recent natural climate variability, but they agree that no sort of natural variability can hold off greenhouse warming much longer. “Our prediction is that if past is prologue, the solar component will turn around and lead to rapid warming in the next 5 years,” says Rind.
Climate modeler David Smith of the Hadley Centre, who was not involved in the State of the Climate analysis, says his group’s climate model forecasts—made much the way weather forecasts are made—are still calling for warming to resume in the next few years as ocean influences reverse (Science, 10 August 2007, p. 746). Whether that’s in time to boost climate negotiations is anyone’s guess.
The ball is back in Richard Kerr’s court. Dr. Kerr, let’s have a five-year update for Science with a headline like “What Happened to Global Warming: Can Mainstream Climate Science Regain Its Footing?” His update might well take into account Judith Curry’s current post, IPCC AR5 weakens the case for AGW), that documented “several key elements … weakening of the case for attributing the warming [to] human influences:
- Lack of warming since 1998 and growing discrepancies with climate model projections
- Evidence of decreased climate sensitivity to increases in CO2
- Evidence that sea level rise in 1920-1950 is of the same magnitude as in 1993-2012
- Increasing Antarctic sea ice extent
- Low confidence in attributing extreme weather events to anthropogenic global warming.”

Jimbo,
The strategy you have for using your lists can be effective. Thanks for letting us know the why of your efforts. And thanks for your efforts.
Speaking of strategy, is there is a shift in strategy used by IPCC apologists particularly wrt the evolution of AR5? Some apologists are no longer able to avoid addressing independent (of the IPCC) critical skeptics; they are debating in absentia with critical skeptics. Is their new strategy what I would call indirection? Where the indirection is trying to take on the appearance of having been all along a skeptic of the IPCC just like the real critical skeptics are. It is indirection when they say, in response to critical skeptics, something like “we are adjusting to new observations”.
John
The lecture by Hayek seems to be a contradiction in abstract steps, if you will.
First, the point:
In some fields, particularly where problems of a similar kind arise in the physical sciences, the difficulties can be overcome by using, instead of specific information about the individual elements, data about the relative frequency, or the probability, of the occurrence of the various distinctive properties of the elements. But this is true only where we have to deal with what has been called, “phenomena of unorganized complexity,” in contrast to those “phenomena of organized complexity”
Would Hayek argue that climate models try to ‘explain’ a non linear, complex chaotic system, that is, a system that is unorganized complexity ? Then, it appears that he would support the climate model approach as valid ? Yet, later, the author pleads :
What I mainly wanted to bring out by the topical illustration is that certainly in my field, but I believe also generally in the sciences of man, what looks superficially like the most scientific procedure is often the most unscientific, and, beyond this, that in these fields there are definite limits to what we can expect science to achieve. This means that to entrust to science – or to deliberate control according to scientific principles – more than scientific method can achieve may have deplorable effects.
And, offers a glimpse of intended summary :
The conflict between what in its present mood the public expects science to achieve in satisfaction of popular hopes and what is really in its power is a serious matter because, even if the true scientists should all recognize the limitations of what they can do in the field of human affairs, so long as the public expects more there will always be some who will pretend, and perhaps honestly believe, that they can do more to meet popular demands than is really in their power. It is often difficult enough for the expert, and certainly in many instances impossible for the layman, to distinguish between legitimate and illegitimate claims advanced in the name of science.
While arguing for the one take away:
A theory of essentially complex phenomena must refer to a large number of particular facts; and to derive a prediction from it, or to test it, we have to ascertain all these particular facts. Once we succeeded in this there should be no particular difficulty about deriving testable predictions – with the help of modern computers it should be easy enough to insert these data into the appropriate blanks of the theoretical formulae and to derive a prediction. The real difficulty, to the solution of which science has little to contribute, and which is sometimes indeed insoluble, consists in the ascertainment of the particular facts.
Concluding with a more general summary:
There is danger in the exuberant feeling of ever growing power which the advance of the physical sciences has engendered and which tempts man to try, “dizzy with success”, to use a characteristic phrase of early communism, to subject not only our natural but also our human environment to the control of a human will. The recognition of the insuperable limits to his knowledge ought indeed to teach the student of society a lesson of humility which should guard him against becoming an accomplice in mens fatal striving to control society – a striving which makes him not only a tyrant over his fellows, but which may well make him the destroyer of a civilization …
I feel that his initial apparent support for unorganized complexity to be ‘understood’ by ‘frequencies’ and/or ‘probabilities’ undercuts the value of his summary with respect to making this piece a critical argument in the ‘climate models are failing’ argument one might be tempted to bring forth. What am I missing here ?
Steve from Rockwood says on January 14, 2014 at 5:49 pm
The difference between a peak and a pause is impossible to discern in the short term. This may not be a hiatus, a pause, a “no-warming in 17 years”. It could be a peak. That would suck.
Sorry Steve – it’s probably going to suck.
Re-stating from 2002:
We knew decades ago that global warming alarmism was wrong. We confidently stated in 2002:
[PEGG, reprinted in edited form at their request by several other professional journals , the Globe and Mail and la Presse in translation, by Baliunas, Patterson and MacRae]
http://www.apegga.org/Members/Publications/peggs/WEB11_02/kyoto_pt.htm
On global warming:
“Climate science does not support the theory of catastrophic human-made global warming – the alleged warming crisis does not exist.”
On green energy:
“The ultimate agenda of pro-Kyoto advocates is to eliminate fossil fuels, but this would result in a catastrophic shortfall in global energy supply – the wasteful, inefficient energy solutions proposed by Kyoto advocates simply cannot replace fossil fuels.”
I suggest that our two above statements are now demonstrably true, within reasonable probabilities.
I also wrote in an article in the Calgary Herald published on September 1, 2002, based on a phone conversation with Paleoclimatologist Dr. Tim Patterson:
On global cooling:
“If (as I believe) solar activity is the main driver of surface temperature rather than CO2, we should begin the next cooling period by 2020 to 2030.”
Bundle up!
Regards, Allan
“If (as I believe) solar activity is the main driver of surface temperature rather than CO2, we should begin the next cooling period by 2020 to 2030.”
I cannot comment of the driver(s) for any proposed cooling. That is way above my pay grade.
I can observe that the temperature data to date (HadCrut4) says that we are over a peak in the 60 year cycle that is demonstrably present and may be experiencing a peak in the underlying 100+ year cycle as well.
http://www.woodfortrees.org/plot/hadcrut4gl/plot/hadcrut4gl/mean:220/mean:174/mean:144/plot/hadcrut4gl/mean:720
So the data now supports your prior observation.

I will also reprint RACookPE1978 comment that explains why the bipolar seesaw could be the beginning of a new ice age:
We may or may not be looking at a major ice age, the jury is still out on that, but with the summer insolation declining in the NH, ([s]olar energy reached a summer maximum (9% higher than at present) ~11 ka ago and has been decreasing since then, primarily in response to the precession of the equinoxes) and near the level for triggering glacial inception, we certainly are not looking at a “Tipping Point” towards warming. At least not for thousands of years.
This is the elephant that stomps all over CAGW alarmism.

We can’t ask Hayek but I would argue that weather is non linear, complex and chaotic and there fore not of unorganized complexity but of self-organizing complexity. As examples it suffices to point to convective fronts or soliton cloud systems like this:
http://en.wikipedia.org/wiki/Morning_glory_cloud
But basically all macrostructures show self-organization. A statistical approach is only valid on a scale that is an order of magnitude bigger than the largest such structure.
Once at the Guardian one commenter lamented why people were claiming a surface temperature standstill. I showed him my list. This way they find it hard to call me the D word as I am simply quoting mostly Warmist climate scientists on their side. It also scrambles their brains.
http://wattsupwiththat.com/2014/01/14/no-matter-if-its-a-climatic-pause-or-jolt-still-no-warming/#comment-1536057
I also grew tired of Warmist telling me “but it’s just one quote” or “the paper is an outlier” etc. So I go for as many as I can conceivably find and block such defences.
Now that the majority of ground based weather stations have migrated from Rural to Urban and airports we will see just how big a jolt we get after the pause, especially with satellites monitoring the ground stations.
Is this what those clowns at the UK met off call science? My god, you poor people. Stupidity is so engrained in the psyche of British government scientists they don’t even recognise their stupidity when placed before their peers. God help us all.
This is dead on the money. But look at the larger issue. It isn’t just “clowns at the UK met office”. This is a paper published in Science!. It contains only ten runs, and without actually getting TFA, I’m guessing ten runs with a single GCM. Ten runs is a pitifully small statistical sample, and isn’t improved by the fact that their conclusion is pure data dredging. The probability of ten year intervals for a given specific model isn’t obtained by looking for them in 10 runs that magically turns 910 years into 700 years without explanation, it would (possibly) be obtained by taking that model and running it 100 times for twenty years from the specific starting conditions corresponding to the model epoch, the point where one sets the initial conditions from actual emprical data to predict the probabilistic future.
If the paper actually uses ten different GCMs, the situation is far worse! In that case, all seventeen of the ten year intervals could have come from (say) three or four of the models, and those models — with multiple ten year intervals of flat temperatures — would very likely produce considerably less aggregate warming than models without them. Then there is the utter fallacy of averaging over GCMs, a fallacy I’ve discussed many times. The average over the results of multiple models is not a statistically meaningful quantity. One cannot justify its convergence to a true mean by the use of the central limit theorem. One cannot even assert that errors from model to model are likely to be symmetrically distributed around a true mean by some other means. The average over multiple models is quite literally a meaningless quantity, where at least the average of an ensemble of runs from a single model is a quantity subject to falsification of the model by means of a p-value generated by comparison to the actual future.
A test, by the way, that whatever model they were using has now egregiously failed. To be specific, the probability of starting the model in the epoch year of (say) 1998 and running the model 1000 times from those initial conditions with a small monte carlo spread for 16 years and observing one single instance of zero warming over all 16 years is probably under 0.5. At a guess, the model fails an honest hypothesis test (if it produced 2+ C of warming over 90 years in the first place) with a p-value order of 0.001 — a knee-jerk reject in most of science.
rgb
These snake oil sellers couldn’t predict the cessation of GW, but now they expect us to believe they know that it is just temporary – mind boggling delusionairies.
If natural variability can once overwhelm GHGs, it can potentially do so at any time. It is thus the ruling factor. As for A-GHGs, there is no real-world evidence of their effects whatsoever, despite Warmist hopes and claims.
I’d like to see how many “5 degrees by 2070″ models have 10-year pauses, but no one has put such a question to the modellers.
Sure they have. You can see the answer explicitly in AR5, in several distinct flavors. Steve McKintyre does a good job of deconstructing them here:
http://climateaudit.org/2013/10/08/fixing-the-facts-2/
Note well the changes made from the comparatively honest presentation in the AR5 draft and what they finally released. Don’t get me wrong — the AR5 initial draft was already misleading enough, as the grey envelopes are meaningless. But so is the spaghetti graph they replaced it with.
A proper treatment would have compared each independent GCM to reality, one at a time, and used the real-world result to reject pretty much all of the hottest GCMs (say, the upper third, the ones that are responsible for the upper part of the shaded grey in the draft report as failed models that should not be taken seriously any more. It would have flagged the middle third clustered around the presented centroid as being suspect models — egregiously/collectively deviating from reality, and given the requirements of avoiding data dredging, collectively weaker than one might even expect by individual comparisons. It would have presented the results from the coolest running models as being not egregiously in contradiction of reality, and weighted those models as being the GCMs most likely — in a statistically defensible sense — of being correct or having some predictive skill.
It might have then extrapolated the predictions of those coolest models to determine the likely warming to the end of the century while downgrading all of their confidences substantially, as basically every single statement made with “high confidence” in AR4 is proven false by time at this point, indicating that they need to back the hell off in their assertions of statistically unjustifiable confidence. Right now they are basically using “confidence” to mean “in the obviously highly biased opinions of the people who are writing the final AR SPMs”, not “based on a reliable statistical estimate derived from independent and identically distributed samples drawn from a common distribution after accounting for other sources of error”.
The former is confidence in the sense of confidence game, a.k.a. a con, a racket, the false presentation of a high degree of confidence that is in fact indefensible or that hides actual falsehood in order to advance some vested interest. The latter is what is usually used in science.
It is also extremely interesting that AR5 has “posthumously” backed way the hell off of their predictions for the mid-century mark even their final draft — but not in the SPM — in an addendum, to a rate that is actually dropping the end-of century warming to less than 2 C — contingent on all sorts of things people cannot predict, such as what Mr. Sun is doing in the latter half of this century, whether or not a few large volcanoes decide to start a decadal sustained eruption, what happens with human energy production, and just how important natural variability is, anyway.
I’ll just make my own prediction. In the real world, it is entirely possible that the warming will resume. Or not. Or it could cool. If at least some of the GCMs are even vaguely correct — something subject to extremely considerable doubt at this point, since some of the GCMs are almost certainly egregiously incorrect based on the comparison of their predictions with nature and since most of the GCMs are in substantial systematic disagreement with nature even where the disagreement is not so severe as to overtly falsify them, yet — at some point the warming will indeed resume. But ever year that it does not more severely constrains the Bayesian most probable values of things such as the climate sensitivity and the probable correctness of various implicit assumptions about climate dynamics in the models, even starting from initial priors with a probably absurd degree of initial confidence. In other words, the longer warming does not resume, the more likely it is that the long term warming will be substantially less than initially predicted, or if you prefer, the range of most probable future temperatures should monotonically decrease with every year of no meaningful warming.
In three more years, if no meaningful warming occurs — and given that we are going to be entering the downside of solar cycle 24 at that point, even the most die-hard warmist has to be worried that it will not, in fact, be warming by then and might even be cooling compared to a 1997-1998 Super-ENSO epoch — the Bayesian estimates will drop to where a catastrophe becomes actively improbable as opposed to actively probable. We’re well on the way there already. Recall that even as of a few years ago, the George Mason survey of climate scientists showed that over half of them thought that there would be warming, but only non-catastrophic levels of warming, by the end of the century. The recent AR5 “stealth modification” means that, if re-polled today, the numbers here would probably have risen to something like 2/3 of all climate scientists thinking there will be damaging but non-catastrophic warming , as few as 20% still believing in catastrophic warming, and a growing minority thinking that there will not even be damaging warming or no warming at all. This is reflected by the free-fall in climate sensitivity, down from order of 2.5 C in AR5 to many estimates under 2 C in late 2013. By 2017, with no warming, these will be falling to non-catastrophic 1.2-1.5 C, basically no water vapor feedback at all, and large uncertainties due to an obviously much larger role of natural variability.
AR6 could well be the final assessment report produced by the IPCC as they are being summarily disbanded and massively defunded. That’s on the far side of the 2016 presidential elections, and no matter who runs for either party, they are going to have to back off CAGW if there has been no meaningful warming by early 2016, two years from now or worse, if there is an actual weak cooling trend, regrowth of arctic ice, etc. By 2017, heads will be rolling. That’s why we are seeing AR5 backing off after the fact. The “cold” reality of the matter is that Trenberth, Schmidt, Jones, Hansen and all of the rest can see the writing on the wall. They are already hoist on the petard of their own egregious past predictions and words. They cannot artificially boost ground surface temperatures derived from UHI-maniplated thermometers as they are constrained by independent LTT measurements and ever better tools supporting truly global satellite measurements of surface temperatures. The trick of pretending that every extreme weather event is evidence of CACC (as opposed to CAGW) is played out — too many people are calling them this even in the scientific community.
If they cannot point to some published science that agrees with neutral warming over 20 year, their objectivity will be called into question, and not just on WUWT, this will be a mainstream event as everybody’s funding is going to depend on whether or not they were deliberately misleading the public. Expect to see a lot of publications this year where people who have for years unambiguously taken CAGW and high climate sensitivity as a given to subtly back off to a fence-sitting posture where they still call for AGW, but start to openly acknowledge that it could end up being only a degree plus, not two degrees or more plus. In other words, objectivity will break out all over so that researchers have a track record of some objective consideration of the possibility of non-catastrophic AGW with low climate sensitivity before the peasants arrive with pitchforks and torches, or before Republicans arrive with subpoenas and the threat of being found in contempt of congress in previous testimony.
In other words, climate scientists who have spoken out confidently for catastrophic warming are suddenly realizing that they might actually be held accountable for their conclusions, and not just in scientific journals. Those who live by the political sword die by the political sword, and the ivory tower quite rightly hold no protection for those who have used science as a cloak for making statements outside of the reasonable confidence that can be attributed to the predictions of unproven theories and unvalidated computational models. Which is “low”, in case there is any doubt.
The worst case scenario for them is actually the best-case scenario for the science. A number of recent papers are uncovering an actual scientific basis for errors in the GCMs, e.g. errors in the treatment of thunderstorms as vertical advection penetration of heat through the greenhouse layer to where one has regionally enhanced cooling at a globally significant level, the discovery that things like stratospheric water vapor can vary by over 10% on a remarkably short time scale for reasons unknown (with truly significant modulation of greenhouse warming, modulation that can actually be semi-permanent if the decrease in water vapor proves to be perisistent), with the discovery that aerosol physics and soot are almost certainly incorrectly treated in many of the GCMs if not most. If somebody writes, or rewrites, some of the GCMs so that they predict the recent temperature hiatus as being probable instead of improbable in their per-model ensemble runs, while still using physics-based models (just with improved physics) then the science itself will be rescued even as those who placed overmuch reliance in the results of early models are marginalized.
Hansen has already been marginalized. Jones has to be worried. Schmidt is vulnerable. Some of these folks actually HAVE a track record of being far more reasonable and conservative about what the predicted pre-1998, pre-Mann, when Hansen, the IPCC and the Green crowd took over the science and made it a global issue to replace war as a UN issue and to (very sadly indeed) displace global poverty, religious conflict, and ignorance as the most important issues facing the world. I think Jones has long since realized that he was wrong but has no way to say so publicly that isn’t committing seppuku, so he keeps praying for potentially disastrous warming to recommence even as he realizes that it probably won’t, at least not during his career lifetime. I think Trenberth is actively backing off as we speak — last I heard he was calling for only 35 cm or thereabouts of SLR by 2100 — far too much to support by direct evidence, but way, way down from Hansen’s TED Talks public assertion of five meters of SLR by 2100. Even as he looks for missing heat, he realizes that if he finds it in the deep ocean, it actually means that there will be no catastrophic warming in the next century — it is good news for the world, not the bad. And then he has to be just as aware as anyone else that climate sensitivity is probably a lot lower than the early GCMs predicted, the role of the natural decadal oscillations and the sun a lot larger than they account for even now, and that feedbacks from water vapor and clouds could even turn out to be net negative even as they very plausibly change the distribution of global temperatures and rainfall patterns.
Over the next decade ARGOS and improvements on CERES are going to tell us a lot, and do so in ways that completely resolve (prove or disprove) many of the assumptions concerning radiative balance. Everybody knows it, and is suddenly realizing that their “confident” assertions from the last two decades are about to be in the position of being falsified, in detail, not by sloppy things like incorrect predictions of upper troposphere warming, incorrect predictions of global warming, but by actual measured failures in the supposed heating of the ocean, in measured failures in the TOA variation of upwelling spectrally distributed intensity or (worse) albedo.
We are also reaching a point in many countries where personal weather stations connected to e.g. the Weather Underground achieve sufficient numbers and detail to precisely map the UHI effect, map it to where precise corrections become possible in at least much of the United States if not Europe. I actually suspect that they are already there, although collecting the data and processing it as a set of anomaly isotherms surrounding urban centers is probably still difficult. I’m pretty happy to bet that we are getting to where we can actually compute regional isotherms, corrected for geography, on top of smoothed population density maps and make quite accurate inferences, though.

“If (as I believe) solar activity is the main driver of surface temperature rather than CO2, we should begin the next cooling period by 2020 to 2030.”

I can observe that the temperature data to date (HadCrut4) says that we are over a peak in the 60 year cycle that is demonstrably present and may be experiencing a peak in the underlying 100+ year cycle as well.

So the data now supports your prior observation.

Hello Richard,
I strongly prefer the satellite data (eg UAH) to the surface data. However, all datasets are showing the “pause” now.
My (our) 2020-2030 cooling prediction came from a conversation with Paleoclimatologist Dr. Tim Patterson at Carleton U. I queried Tim closely about the basis of this cooling prediction, since I favour the ~60-year PDO Cycle, but Tim was confident that the ~90 year Gleissberg Cycle was more likely to dominate the global climate system, based on his research.
IF the ~60 year PDO dominates, then cooling has probably already begun. However, any such cooling is still small and difficult to detect.
Yet another time — Piazza is a tool I use in teaching physics. It facilitates blog-like discussions of specific questions. It can correctly translate inline latex wrapped in $$ pairs, so that $$\vec{F} = v\vec{a}$$ is Newton’s Second Law. It has a built in preview — you can check your replies, including all rendered latex as well as trivially embedded graphics. Webassign (another tool I use) can handle tagged latex as well, and again there is ownership of individual posts so I can edit what I say even after it is posted. Goodreads is a reading blog — actual blog software — that permits previewing one’s post, editing one’s own post, and a lot more, all easily and conveniently. No latex, but then it isn’t a science blog tool.
There are things like http://www.mathjax.org/, javascript tools that permit the embedding and display of mathml and/or latex into rather generic blog engines. I pray for WUWT to aggressively pursue this sort of thing. It is a real pain in the ass to try to write in a science-related blog without either preview or a proper latex/mathml/mathematica interface. And this isn’t the only such tool. Surely something out there would enable graphics, math, previewing, after-post editing by the submitter (and moderator(s))?

So, we can expect Nuttycello to castigate Kerr and Schmidt for admitting that there IS a pause in “global” warming that isn’t global. Right?

Thanks for the excellent summarization. I wanted to second your assessment of “unjustified confidence”. It is one of the most egregious violations of the scientific method to falsify the significance of the supporting evidence. Claiming a level of confidence, that is unjustified, is undermining the “level of confidence” the public has in its institutions. The difference between civil society and anarchy, is the level of trust, that the public maintains for the “ruling class”. If those at the top, are not punished for violations of public trust, you can be sure, the public is not going to abide by the behavioral norms, that make society function.
It will get worse, before it gets better. There are still a significant number, of otherwise intelligent individuals, with there eyes shut and there fingers in their ears, praying for a massive “El Nino” this summer. It will make a good thesis on “mass psychosis”, for some future dissertation.
I hate to think where we would be, without the numerous internet sites, that have weathered withering condemnation from the “climate aristocracy”.
It will at least be a lesson, to others, that want the celebrity that comes from setting off the “fire alarm” when you think, you might, smell a puff of smoke.
So, this is just a blip caused by other factors and warming will resume? Presumably then, there will be a snap-back effect and the warming will appear to accelerate dramatically as the blip reverses and adds to the underlying warming trend. So… why have warming projections been reduced and not increased?
1971 according to NASA, consensus man made climate change is absurd: http://stevengoddard.wordpress.com/2014/01/15/1971-consensus-mann-made-climate-change-is-absurd/
In Australia, the recently setup climate council, headed by sacked Tim Flannery, is stating that warming is happening faster than ever now. Seems only to affect Australia though.
