The Greatest Climate Myths of All – Part 2.

Guest essay by Jim Steele,

Director emeritus Sierra Nevada Field Campus, San Francisco State University and author of Landscapes & Cycles: An Environmentalist’s Journey to Climate Skepticism

In part one, I wrote “In the simplest of terms, every study that has attributed the recent warming of the 1980s and 90s to rising CO2 has been based on the difference between their models’ reconstruction of “natural climate change” with their models’ output of “natural climate change plus CO2.” However the persistent failure of their models to reproduce how “natural climate changed before,” means any attribution of warming due to CO2 is at best unreliable and at worse a graphic fairy tale.”

Like failed modeling results illustrated in Part 1, scientists at the University of East Anglia’s Climatic Research Unit published Attribution Of Polar Warming To Human Influence1. Again their models failed to account for the heat during Arctic’s earlier natural warming (black line), a warming climate scientists called “the most spectacular event of the century”. Their “natural models” grossly underestimated the 40s peak warming by ~0.8° C (blue line) and when CO2 and sulfates were added the warming event was cooled further (red line). So how much do we trust models’ attribution when they get climate change half wrong?

Over millennial time spans, researchers reported similar failures reconstructing the Medieval Warm Period writing, “Inter-model differences and model/reconstruction comparisons suggest that simulations of the Medieval Climate Anomaly either fail to reproduce the mechanisms of climate response to changes in external forcing, or that anomalies during this period are largely influenced by internal variability.“2 Modeling also fails at smaller regional levels with superior data coverage, such as California. As Dr. Phillip Duffy, Lawrence Livermore National Laboratory, wrote “Neither the nature of climate trends in California nor their causes are well understood.”3

Sidestepping such failures, alarmists note models can generate random unforced warming events about every 150 years and that last a decade or so. And so they suggest early Arctic warming was a random event caused by “internal variability” that can’t be modeled. But there was less than a 13% chance that random warming happened in the 30s, and that random warming could have equally contributed to the 80s and 90s, meaning CO2 contributed little. And that arguments does not alter the fact that CO2-driven climate models fail to reproduce natural climate change of the past.

Alarmist believe CO2 is the “control knob” of climate change and Dr. James Hansen, who studied climate on lifeless planets devoid of oceans, proselytizes that belief. On other planets the “radiative balance” is the critical climate variable. But that narrow focus has biased Hansen and his disciples who have underestimated the power of ocean oscillations. Fortunately here on earth, there is a growing awareness that natural ocean oscillations persist for many decades and control how heat is stored, redistributed and ventilated. Those oscillations increasingly appear to be the most powerful “climate control knobs” and many advocates of CO2 warming now blame the cool phases of these ocean oscillations for “masking” or “hiding” hypothesized heat. But natural ocean oscillations have also raised temperatures, and regards to understanding both 20th century warming events in the Arctic, ocean oscillations offer the superior explanation.

From latitudes 40° North or South to the poles, the earth increasingly ventilates more heat than it absorbs. Climate change at those higher latitudes is dominated by variations in the transport of surplus tropical heat. Scientists estimate “Without these heat transports the atmosphere would have an equator-pole surface air temperature difference of 100° C, which is more than twice the present value of 40°C.4 Equally important, surplus equatorial heat is generated by the sun, with a very small and dubious contribution from CO2. As reported by the IPCC in the Physical Science Basis, “In the humid equatorial regions, where there is so much water vapour in the air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation. However, in the cold, dry polar regions, the effect of a small increase in CO2 or water vapour is much greater.”

clip_image004

However both 20th century Arctic warming events are associated with greater volumes of warm water intruding into the Arctic driven by the warm phases of the Pacific Decadal Oscillation, the Atlantic Multidecadal Oscillation and the Arctic/North Atlantic Oscillation. And as would be expected, the poleward range of southerly marine organisms has ebbed and flowed accordingly.

In a 2013 peer-reviewed paper,5 scientists examined the migration of marine organisms into the Arctic reporting, “The fauna of the southern North Sea exhibits clear changes. Particularly conspicuous is the increase of Mediterranean fish species and the occurrence of sardine eggs and larvae. There is no doubt, that these observations are associated with the climate change which has been shown to occur since several decades, and which, over the last years, has had important consequences for fisheries: decrease of catches, northwards shift of fishing grounds, adaptation to fisheries for different species. …particularly interesting questions are: will climate change continue and, also, shifts and changes of fish stocks, how long will this last, and which are the consequences, if this trend reverses?”

Sounds familiar, but the above quote was written by Aurich in 1953. Like the earlier warming event and migrations, the most recent northward advance of small fish such as sardines, anchovies and herring correlate very well with the Atlantic Multidecadal Oscillation and the current distribution of fish from southerly waters is “almost identical to that described by Aurich for 1951.”5 After the earlier warm event those fish retreated and were absent from the North Sea surveys during the 1970s and 90s. So the next few decades should provide the evidence needed to settle much of the climate debate. If natural cycles are indeed the climate control knob, the next 2 decades should witness a cool phase of the AMO and the retreat of southerly marine organisms. And the current scientific consensus that the upper 300 meters of the oceans have been cooling since 2003 bodes well for natural cycles prediction.13

To support dubious climate model attributions, the scientific literature has been increasingly spammed with papers creating the second greatest climate myth: migrating organisms are evidence of CO2 driven warming. However their arguments fail to account for the myriad of confounding factors affecting the biosphere. The same biological evidence used to instill CO2 fear, is also consistent with interpretations attributing landscape changes and/or natural climate cycles that modulate heat transport to the poles. If marine organisms migrated similarly pre-1950s when CO2 was an insignificant player, then the most parsimonious explanation is identical migrations today are driven by the same natural forces.

clip_image006

Good science demands we examine how climate changed naturally in the past, not to uncritically dismiss the possibility of CO2–caused warming, but to understand to what degree present climate change is driven by historical cycles. Only by thoroughly examining climate history can we estimate natural contributions and evaluate earth’s sensitivity to rising CO2. This is most critical because climate history is now repeating itself.

However those eager to blame rising CO2 have downplayed natural oscillations. Alarmists recently published Global Imprint Of Climate Change On Marine Life,” which press releases hyped in the media. Alarmist websites like ClimateProgress ranted, “The research is more confirmation that “global change is real and has been real for a long time. It’s not something in the distant future. It is well underway.”

The truth is natural cycles are well underway, as they always have been. And that dynamic is being hijacked.

The “Global Imprint” analyses suffered from the same shortcomings uncovered in inflated claims that 97% of the scientists agree about climate change. The authors similarly surveyed on-line abstracts from which they extracted only papers suggesting ecological changes were driven by climate change. Their filter effectively removed all analyses examining other confounding factors. Furthermore most of the papers in their compilation only studied responses during the warm phases of natural ocean cycles beginning in the 70s, after most marine organisms had retreated south. Thus their meta-analyses totally obscured the cyclic warming and cooling that accompanied those migrations during the 20th century. From their carefully filtered database, they claimed, “81–83% of all observations for distribution, phenology, community composition, abundance, demography and calcification across taxa and ocean basins were consistent with the expected impacts of climate change.”8

But like the “97% consensus” methodology, their 83% disguised the fact that the vast majority of species were non-responders. Of the 857 species examined, only 279 (or 33%) changed distribution. Sixty-seven percent had no response and therefore “were not included because failure to detect a change in distribution may have several causes, including barriers to dispersal, poor sampling resolution or the dominance of alternative drivers of change.” Changes in distribution also has several caused but again their data selection guaranteed a statistical bias. If all the 857 species were accounted for, a mere 27% behaved in a manner “consistent” with CO2 theory. More importantly most of those species were also behaving in a manner consistent with natural cycles.

It was not surprising to see the IPCC’s Camille Parmesan co-authored this paper. As I have documented before Parmesan has “inaccurately” blamed CO2 warming for extinctions due to lost habitat from urban sprawl, hijacked conservation success to argue poleward movement of butterflies was caused by climate change, and blamed CO2 and extreme weather for a population extinction caused by logging while neighboring natural populations thrived. Now she again hijacks marine migrations caused by natural climate oscillations as “proof” of global warming. And both the “Global Imprint” lead author and Parmesan co-authored a paper contradicting scientific consensus, arguing “Species’ extinctions have already been linked to recent climate change; the golden toad is iconic.15

In contrast to the fearful “science via press release,” the peer-reviewed literature is filled with evidence that supports a more parsimonious natural cycles explanation. In 1997 fishery biologists (not climate scientists) discovered the climate changing Pacific Decadal Oscillation (PDO) after realizing that every 20 to 30 years salmon abundance shifted between Alaska and Oregon. When the PDO entered it positive phase around 1976, biologists observed northward migrations of plankton, fish and bottom dwelling organisms. Likewise temperatures increased. Climate scientists also reported “when the PDO value changed from dominantly negative to dominantly positive values, a sudden temperature increase across Alaska was observed.”6 After the 1997 El Nino, the PDO began to trend back to its negative cool phase. Sea surface temperature anomalies reverted “to that seen throughout the North Pacific before 1976.”14 Bering Sea ice began to increase reaching record extent in 2012 and Alaska became one of the most rapidly cooling locations on earth as the average for Alaskan weather stations experienced a extraordinary temperature drop of 1.3° C for the decade.6

As eastern Pacific temperature trends from Alaska to the Southern California Bight reversed, species of fish that had once moved northward are now retreating southward. Researchers in the Southern California Bight reported that above all other environmental factors, the changes in fish abundance has correlated best with the PDO regime shifts.7 Such evidence prompted Monterrey Bay Aquariums chief scientist to warn that “These large-scale, naturally occurring variations must be taken into account when considering human-induced climate change and the management of ocean living resources.”8 After all it was the shifting PDO that disrupted Monterrey’s fishing industry as described by John Steinbeck in Cannery Row.

In the Atlantic, poleward intrusions of warm water driven by natural cycles have similarly altered sea ice and the distribution of marine organisms. Satellite pictures (below) clearly show that the recent loss of winter Arctic ice has occurred along the pathway by which warmer waters enter the Barents Sea, deep inside the Arctic Circle, while simultaneously air temperatures far to the south remain cold enough to maintain a frozen Hudson Bay. Before those warm water intrusions facilitated the loss of sea ice, air temperatures in the 80s and 90s reported a slight cooling trend contradicting CO2 theory.12

clip_image008

Much of the warming in the Arctic in the 20s and 40s, as well as in recent decades was likely due to increased ventilation of ocean heat after sea ice was reduced by intruding warm water and the altered atmospheric circulation. A comparison of Danish Sea ice records from August 1937 with satellite pictures from August 2013, illustrate very similar losses of Arctic ice. As would be expected, a slightly greater proportion of thicker sea ice formed during the Little Ice Age would likely remain during the first warming event compared to recent decades. The slightly warmer Arctic temperatures of the recent decade can be attributed to a greater loss of thicker multiyear ice that is ventilating more ocean heat. But past performance never guarantees the future. Scientific opinions and predictions must be validated by experimentation or future observations. If indeed natural cycles are the real climate control knobs, the next 15 to 20 years will settled the debate. While alarmists predict total loss of ice by 2030 (and earlier predictions have already failed), believers in the power of natural cycles expect Arctic sea ice to rebound by 2030. Until then the science is far from settled. And claims that the science is settled just one more of the great climate myths. (Part 3 will look at the chimeras created by averaging and meta-analyses)

But that narrow focus has biased Hansen and his disciples who have underestimated the power of ocean oscillations.
Bingo.
Of course, Hansen was making his projections before the PDO was described by science (i.e., 1996). So he ascribed the natural PDO warming to CO2 alone. Take it from 1950 when CO2 became significant and we see 1.1C/century warming. That’s over one complete PDO cycle (so that balances). So we see CO2 forcing according to Arrhenius — without net positive feedback.
And that’s assuming the sensors are accurate, and 4 out of 5 of them ain’t.

Another nail in the coffin of CAGW – thanks…

Outstanding summation of the Arctic issues. A joy to read . We can learn so much more about global warming by simply going back a little longer than just the last 30 years or so. When warmists show everything is unprecedented, they will have a convert. So far they haven’t come close.

M Courtney

It’s CO2…
It’s the Sun…
It’s the Oceans…
It’s all and none of these. Just because the redistribution of heat from ocean currents is consistent with polar temperature observations does not mean it is the sole or even dominant cause.
Climate is complex.

evanmjones says: “Of course, Hansen was making his projections before the PDO was described by science (i.e., 1996). So he ascribed the natural PDO warming to CO2 alone.”
The PDO represents the spatial pattern of the sea surface temperature anomalies in the North Pacific, not the sea surface temperature anomalies. There is no mechanism through which the PDO can alter temperatures globally. Please refer to:

What a clear illustration of the extent to which science has been blinded by the UN and Governments funded CO2 mantra. I wonder if scientists who have entered the fields of ‘climate change’ in the last 10 – 20 years are actually still capable of critical appreciation of true science and the extent to which you must look to explore all possible causes and explanations.
CO2 and ‘global warming’ is not about climate it is about deeply infiltrated and, typically, well-concealed marxist politics. It is all about creating ‘obedience’ to a doctrine by fabricating a climate of fear about climate.
Many ‘free-market’ politicians have been seduced by the power it gives them to raise taxes – while marxists use it to gain power and control over people’s lives. The ‘green’ organisations have gained unparallelled power and influence since embedding themselves within politics – to the extent that in europe they are funded by the EU to advise them on policy!
The UN wants to use it to create an unelected global government. The Third World leaders see it as a gravy train – but either don’t appreciate or ignore the perils of ‘benefit dependency’ (vividly understood and illustrated in the UK where now some families are in their 3rd generation of not working).
In a very real sense democracy is under severe threat; science no less so given the huge number of scientists have been subverted by the financial imperatives of the CO2 bandwagon; funded by politicians hungry for ever-increasing power and taxes.
At least some world leaders (Australia and Canada) are now beginning to expose this sham for what it is – the sooner that others follow the sooner this wanton, highly politicised destruction of western economies will be brought to an end – and the sooner science may return to actually being that.

But there was no natural variation before C02 started its rise.Temperatures were flat. We know this from Mickey’s hokey schtick. So there’s nothing to explain.

Thanks for this post Jim, I much admire your work on the role of natural cycles. As an ecologist re-examining my own prior acceptance of ‘global warming’ , knowledge of natural cycles was the first thing I looked at – and I realised how little was known about ocean oscillations. However, it was immediately obvious that several key cycles had peaked together in the global warming period (1980-2000)….the PDO/AMO/AO/NAO and ENSO, and that on top of an ill-defined long-term cycle of 800-1200 years. Yet, the modellers insisted that natural temperatures would have been flat since 1950!!! I was outraged by the level of stupidity shown by modellers such as Hansen and his descendents. I was impossible to communicate to my scientific friends, especially in academia, the sheer level of stupidity – because it was so truly unbelievably naive.
I did get some insight much later on a visit to a NOAA lab, talking with specialists in ocean heat transfer (like you, I realised that here would lie the key to the natural dynamic) – when I asked about how they represented cycles, the reply was ‘we don’t believe in cycles’!!! More accurately – natural cycles are not exact enough to be called cycles (from a physicist’s perspective, brought up on Herz, this is understandable)….but then they don’t seek mechansims – instead, seeking such kind of mathematical formula to encompass the range of natural variability (hence losing all predictive power). Thus, the current flat-line is simply an outlier – it is random with no natural driver!
The vast majority of published climate papers on biodiversity responses simply accept the modellers ‘understanding ‘ of the biosphere, without realising (or caring) what they do. I have been looking at bird distributions in Europe and various attempts to predict the response to warming (by calculating ‘climate space’ for each species). Firstly, there are always winners and losers…but whatever the balance (it is usually about equal – with a high proportion of neutrals, the conclusions still talk up the ‘threat’ of climate change. Secondly, any recent trend is assumed to be caused by the recent climate changes (about 1 degree between 1975-2005 in Central Europe), which are themselves regarded as unique and caused by greenhouse gases.
I have been trying with my limited spare time (and not a drop of oily money) to check the trend over the last ten years – certainly, unquantified information from the field, shows either a reversal or standstill in such factors as early breeding. Data for the central European spruce forests, recently devastated by bark beetle, shows a flat-line in T over the past decade. Of course, outbreaks of bark beetle, as in the USA, were seen in the past warm cycles – co-incident with strong wind damage. I would love to get a clearer sense of how the ocean cycles affect the European flora and fauna – but of course, data is hard to come by. My favourite graph is from Solanki, showing reconstructed solar (magnetic) activity through the Holocene – the 8000BP peak: pelicans nesting in Somerset; 5000BP peak: settlement of the Scottish Highlands; 2000BP peak: vineyards on the Scottish border; 1000BP peak: white stork nested in Edinburgh; recent warm peak: Little Bittern and Great White Egret nesting in Somerset. Sadly, there were few bird-recorders active in the Little Ice Age!
I am compiling a list of all European bird species that are increasing (over the past three decades) and all that are decreasing, as well as neutrals, with material on potential causes – and will post this when available, and in comparison with modeled expectations of loss and gains.

A side issue is that those promoting the climate crisis are doing so for money. Paul Ruben, investment banker and former Treasury Secretary, has decided that we must have an American carbon tax to save the world. Because he thinks there is a 1% chance that Florida could be hit by bad storms in the next 100 years.
So he thinks a tax designed to reduce CO2 can control the weather. Not new infrastructure, not upgrading the infrastructure we have. Instead an area famous for stormy weather can only be saved by more money to the government.

Under real science the hypothesis would have been discarded long ago since it was falsified. But then the grant money moved in and it became a project of proving a conclusion. So the data was fudged to prolong the myth. It cannot last forever. But it can last a lifetime – and that is all they are looking for at this point.

And the current scientific consensus that the upper 300 meters of the oceans have been cooling since 2003
I think measurements are more important than consensus.

” However the persistent failure of their models to reproduce how “natural climate changed before,” means any attribution of warming due to CO2 is at best unreliable and at worse a graphic fairy tale.”
I agree with that observation completely. I would further add that we do not even have an accurate temperature time series to work with to make comparisons. As has been recently pointed out, the entire temperature history changes constantly. This just complicates trying to find out what variability is natural and what is not.

Climate is complex.

The sun is the constant, not the variable. The ocean’s are the variable (and therefore most responsible for climate change). CO2 is not the control knob. As a green house gas a little added CO2 offers no real change to a green house gas filled atmosphere. I’m surprised it has taken so long to study the oceans. Monitoring ocean temperature seems much more important than atmosphere temperature for longer than annual temperature variation. In my mind anyway…
Nice post Jim.

Catcracking

Excellent Post
I have a much better understanding of the impact of Ocean Oscillations.

Bob Tisdale says “There is no mechanism through which the PDO can alter temperatures globally”
Driven by El Nino events the change in the pattern of sea surface temperatures alters pressure systems and thus circulation patterns. The PDO like the Atlantic Multidecadal Oscillation great swathes of regional climates and thus global climate.

@Peter Taylor “I am compiling a list of all European bird species that are increasing (over the past three decades) and all that are decreasing, as well as neutrals, with material on potential causes – and will post this when available, and in comparison with modeled expectations of loss and gains.”
I look forward to seeing your list.
CD Thomas’s papers got some hype about shifting bird populations.due to climate change but his methodology ignored confounding factors and inter-annual variations. Yet he gets headlines for claiming over 30% of the species are committed to extinction.
In the Sierra Nevada, due to changes in snowpack we birds move up and down slope changing abundance from year to year.Trends can change sign depending starting and end dates.

So, in short, if one cannot explain the historical climate, then one cannot presume to PREDICT the future climate. And that is because the many, many variables that can influence the climate ( this assumes that ALL the significant variables are known), and the manner in which they interact are simply not well understood.
I have always been puzzled by many of the articles on WUWT that utilize “advanced” statistical methods to tease out correlations in present or relatively recent climate trends , despite the clear FACTS that the HISTORICAL climate has been beyond the capability of anyone to explain !!
What caused the ice ages? What caused them ALL to end in “global warming? What caused the very many periods of warm periods to end and “turn into” ice ages?” How is it that CO2 levels during some previous ice ages were far higher than today?” Etc. etc. etc
If simple questions cannot be answered, then it is very plain that the “fix” is in. It will eventually be demonstrated that the AGW hypothesis is the biggest scientific hoax in the history of the world . Too bad the perpetrators of this hoax cannot be prosecuted for fraud.

JohnTyler:
One should be careful in using the word “predict” in making a climatological argument. In the climatological literature, “predict” is a polysemic term, that is, it has more than one meaning. It follows by logical rule that when this term is used in making an argument, a conclusion may not properly be drawn from this argument. To draw such a conclusion is an example of an “equivocation fallacy.” Further information on this topic is available at http://wmbriggs.com/blog/?p=7923 .

The notion that each change in the global temperature can be meaningfully separated into natural and CO2-forced components is a mistaken and scientifically disastrous doctrine of global warming climatology. The thinking is that the natural component is a kind of “noise” while the CO2-forced component is an a kind of “signal” (the so-called “anthropogenic signal.”)
Signal and noise are, however, ideas borrowed from telecommunications engineering. In a telecommunications system, information flows from the present to the future; thus, this information can be carried by a wave travelling at subluminal speed. On the other hand, in a control system, information flows from the future to the present; thus it can be carried only by a wave travelling at a superluminal speed but a superluminal is impossible under the theory of relativity.
The notions of “signal” and “noise” do not apply to a control system but control of the climate is what is being attempted by the makers of governmental policy on CO2 emissions. Rather than focusing their efforts on the impossible task of detecting a nonexistent anthropogenic signal, climatological researchers need to focus their efforts upon moving as much information from the future to the present as possible. This, however, they have failed to do.

In your post at June 27, 2014 at 7:21 am you say

Riiiiggghht. So, according to you, the thermostat in my living room contains a time machine and is an impossible device according to relativistic theory.
Terry, I can tell you that the thermostat in my living room does work and empiricism trumps theory.
Richard

richardscourtney:
Thank you for giving me the opportunity to clarity.
The prohibition on superluminal speed is for mass-bearing particles. Relativity theory imposes no prohibition on superluminal speeds in massless particles.
Over the past 50 years, the theoretical physicist Ronald Christensen (and colleagues of his that include me) have built a number of statistically validated optimal decoders of messages from the future for application in controlling systems. The success of these decoders demonstrates the feasibility of moving information from the future to the present. On the other hand, there is no record of success in attempts at moving material particles from the future to the present; modern global warming climatology assumes this kind of movement.

The notions of “signal” and “noise” do not apply to a control system
Of course they do. Unless you are thinking of a natural system where it is all signal.

Terry Oldberg:
In your post at June 27, 2014 at 7:35 am you yet again make the untrue assertion

In the climatological literature, “predict” is a polysemic term, that is, it has more than one meaning

You have asserted that falsehood many times and been corrected on it repeatedly.
The IPCC AR5 Glossary provides clear and unambiguous definitions of climate prediction and climate projection at http://www.climatechange2013.org/images/report/WG1AR5_AnnexIII_FINAL.pdf
These are they
Climate prediction A climate prediction or climate forecast is the
result of an attempt to produce (starting from a particular state of the
climate system) an estimate of the actual evolution of the climate in
the future, for example, at seasonal, interannual or decadal time scales.
Because the future evolution of the climate system may be highly sensitive
to initial conditions, such predictions are usually probabilistic in nature. See
also Climate projection, Climate scenario, Model initialization and Predictability.
Climate projection
A climate projection is the simulated response of
the climate system to a scenario of future emission or concentration of
greenhouse gases and aerosols, generally derived using climate models.
Climate projections are distinguished from climate predictions by their
dependence on the emission/concentration/radiative forcing scenario
used, which is in turn based on assumptions concerning, for example,
future socioeconomic and technological developments that may or may
not be realized. See also Climate scenario.
I do not know why you persist in asserting your falsehood.
Richard

Thanks to Mssrs. Steele and Tyler.

Matt Skaggs

Richard,
Claiming these definitions are unambiguous does not make it so. Please describe how you make a climate prediction that does not involve dependence upon “the emission/concentration/radiative forcing scenario used.” The distinction looks like nonsense to me.

richardscourtney

Matt Skaggs:
Thankyou for your post at June 27, 2014 at 8:43 am which says

Richard,
Claiming these definitions are unambiguous does not make it so. Please describe how you make a climate prediction that does not involve dependence upon “the emission/concentration/radiative forcing scenario used.” The distinction looks like nonsense to me.

There is a difference between a process being unambiguosly defined and being possible of production. In the case in question, the defined predictions and projections are each possible at least hypothetically.
The IPCC says it makes “probabilistic” predictions starting from a particular state of the climate system”.
This is fundamentally different from its “projections” which are based on estimates of future atmospheric greenhouse gas concentrations.
It should be noted that to date all their predictions and all their projections have been wrong. But that does not stop their predictions and projections from having been made.

I will believe that you have “statistically validated optimal decoders of messages from the future” when you correctly inform me of next week’s lottery numbers. My winnings will be all the “statistical validation” I need.
Your “clarification” does not convert the nonsense of your original post into sense. I repeat what I first said in response to it

So, according to you, the thermostat in my living room contains a time machine and is an impossible device according to relativistic theory.

Richard

richardscourtney:

I know that entering the rabbit hole is a mistake but I am going to do it again.
In your post at June 27, 2014 at 7:21 am you said

On the other hand, in a control system, information flows from the future to the present; thus it can be carried only by a wave travelling at a superluminal speed but a superluminal is impossible under the theory of relativity.

And I replied

Riiiiggghht. So, according to you, the thermostat in my living room contains a time machine and is an impossible device according to relativistic theory.
Terry, I can tell you that the thermostat in my living room does work and empiricism trumps theory.

You have now said at June 27, 2014 at 9:27 am

I did not claim that the thermostat in your living room contains a time machine. Thus, the conclusion of your argument is based upon a false premise.

That only makes sense if my thermostat is not a “control system”. So, what do you think it is?
And, importantly, your post at June 27, 2014 at 9:27 am contains the statement which says my thermostat is not a “control system” but forgets to provide the requested information concerning next week’s lottery numbers. I could use the money.

Terry Oldberg;
Over the past 50 years, the theoretical physicist Ronald Christensen (and colleagues of his that include me) have built a number of statistically validated optimal decoders of messages from the future for application in controlling systems. The success of these decoders demonstrates the feasibility of moving information from the future to the present.

Here we go again – another construct with a basic starting point that tries to deny CO2 causes warming.
Other factors ? Yes of course. It a very complex system.
However Jim Steele, getting back to CO2, if it is of so little consequence, tell us what happens if you reduce the concentration in the atmosphere. Presumably little changes ?
BTW, are we going to have a posting on the May NOAA data ?
“The combined average temperature over global land and ocean surfaces for May 2014 was record highest for this month, at 0.74°C (1.33°F) above the 20th century average of 14.8°C (58.6°F).”

However those eager to blame rising CO2 have downplayed natural oscillations.

Then when the temperature standstill came along they played up natural oscillations! Wow!

Of course, Hansen was making his projections before the PDO was described by science (i.e., 1996).

Hansen made his congress speech in 1988.
The IPCC was set up in 1988.
Steven Hare coined the term “Pacific Decadal Oscillation” (PDO) in 1996.
At this time the activists were pushing hard. Maurice Strong et al pushed the co2 genie to the max.

You claim that “…your post at June 27, 2014 at 9:27 am contains the statement which says my thermostat is not a ‘control system'” What I actually say is “I did not claim that the thermostat in your living room contains a time machine. Thus, the conclusion of your argument is based upon a false premise.” What I actually say is inconsistent with your characterization of it.
Your attempt at refutation seems to be of the form of a strawman argument. You attribute to me the claim that your thermostat contains a time machine and refute this claim by the observation that the existence of a time machine violates relativity theory. However, this attempt fails for at no point have I claimed that your thermostat contains a time machine.

Doug Proctor

The appearance of global change can be the mathematical result of summing regional changes. The changes exist, but they are not “global” in the sense that something comes in to change all the regions but some more than others.
The Earth is a gigantic heat redistribution engine. If it weren’t, at perigee (Jan), the closest position to the sun, we would be hugely hotter than at apogee (July), the furthest from the sun, and the Southern Hemisphere would be the hotter place: our 3% orbital eccentricity results in a 6.8% difference in SI, which at TOA would be a 22.8 W/m2 power difference (av whole Earth, 24 hour day). In fact, the Northern Hemisphere is about 2C warmer on average than the Southern, due to different land-ice-water ratios (and their different heat capacities, thermal properties etc.).
The assumption of global temperatures meaning something in the 30 year-time frame is that there is an efficient and continuous heat redistribution system in operation that smooths out any variation in heat content and location within a 15 year period. If that is not true, then at times the atmosphere will warm or cool because SI energy is more dominant in that part of the world than the other. If as Trenberth as heat can unexpectedly bypass the atmosphere and land and ice and go deep, it can come out of the deep unexpectedly. Another assumption that has no empirical evidence – otherwise Trenberth could not pull this alleged rabbit out of his hat as an “explanation” for The Pause.

@ James Abbott
Why do you misconstrue what is written. I have never denied that CO2 is a greenhouse gas or that its levels have risen. I do question the degree of climate sensitivity to CO2, and I adamantly assert and document that we have not witnessed any catastrophic ecological disruptions caused that can be attributed to rising.To be good stewards of the environment we must understand its complexities but as shown above alarmists try attribute everything to CO2.
I wrote, “Good science demands we examine how climate changed naturally in the past, not to uncritically dismiss the possibility of CO2–caused warming, but to understand to what degree present climate change is driven by historical cycles. Only by thoroughly examining climate history can we estimate natural contributions and evaluate earth’s sensitivity to rising CO2. This is most critical because climate history is now repeating itself.”
I have presented an explanation for Arctic warm events and poleward migrations that the best CO2 models have failed to simulate.
If you are truly trying to advance the science, perhaps you can provide us with a better explanation as to why models fail to recreate the early Arctic warming, as well as underestimated the recent loss of Arctic Ice while overestimating the loss of Antarctic ice which continues to grow. The effects of natural cycles and warm water intrusions parsimoniously explains all those CO2-driven model failures as discussed in Why Antarctic Sea Ice Is the Better Climate Change Indicator

More about earlier poleward migrations
Drinkwater, K. (2006) The regime shift of the 1920s and 1930s in the North Atlantic. Progress in Oceanography vol. 68, p.134–151.
During the 1920s and 1930s, there was a dramatic warming of the northern North Atlantic Ocean. Warmer-than normal sea temperatures, reduced sea ice conditions and enhanced Atlantic inflow in northern regions continued through to the 1950s and 1960s, with the timing of the decline to colder temperatures varying with location. Ecosystem changes associated with the warm period included a general northward movement of fish. Boreal species of fish such as cod, haddock and herring expanded farther north while colder-water species such as capelin and polar cod retreated northward. The maximum recorded movement involved cod, which spread approximately 1200 km northward along West Greenland. Migration patterns of ‘‘warmer water’’ species also changed with earlier arrivals and later departures. New spawning sites were observed farther north for several species or stocks while for others the relative contribution from northern spawning sites increased. Some southern species of fish that were unknown in northern areas prior to the warming event became occasional, and in some cases, frequent visitors. Higher recruitment and growth led to increased biomass of important commercial species such as cod and herring in many regions of the northern North Atlantic. Benthos associated with Atlantic waters spread northward off Western Svalbard and eastward into the eastern Barents Sea. Based on increased phytoplankton and zooplankton production in several areas, it is argued that bottom-up processes were the primary cause of these changes. The warming in the 1920s and 1930s is considered to constitute the most significant regime shift experienced in the North Atlantic in the 20th century.

I think you need to re-read your own words.
You said
“any attribution of warming due to CO2 is at best unreliable and at worse a graphic fairy tale”
That’s pretty one sided I would suggest.

The process that you characterize as “the Mad Hatter’s Tea Party” is what most of us call “logic.”
Richard, I do believe that Terry has nicely summed up his problem!

@ James Abbott You cut my sentence in half to twist your point, smear tactics reminiscent of Slandering Sou. My argument is that we can not use model attribution studies to blame CO2 if those models fail to reproduce natural climate change. By most published accounts climate scientists consider the warming events from the 20s to 40s as natural and CO2 was insignificant.
So read the whole sentence.”However the persistent failure of their models to reproduce how “natural climate changed before,” means any attribution of warming due to CO2 is at best unreliable and at worse a graphic fairy tale.”
Do you deny the models failures??
I still await your constructive criticisms that provide a better scientific explanation from which a more informative debate could ensue.

Jimbo

I remember something from a few years back concerning IPCC’s Dr. Mojib Latif. Indeed the next 15 years should settle the debate.

Letter To Nature – 8 May 2008
Advancing decadal-scale climate prediction in the North Atlantic sector
The climate of the North Atlantic region exhibits fluctuations on decadal timescales that have large societal consequences. Prominent examples include hurricane activity in the Atlantic1, and surface-temperature and rainfall variations over North America2, Europe3 and northern Africa4. Although these multidecadal variations are potentially predictable if the current state of the ocean is known5, 6, 7, the lack of subsurface ocean observations8 that constrain this state has been a limiting factor for realizing the full skill potential of such predictions9. Here we apply a simple approach—that uses only sea surface temperature (SST) observations—to partly overcome this difficulty and perform retrospective decadal predictions with a climate model. Skill is improved significantly relative to predictions made with incomplete knowledge of the ocean state10, particularly in the North Atlantic and tropical Pacific oceans. Thus these results point towards the possibility of routine decadal climate predictions. Using this method, and by considering both internal natural climate variations and projected future anthropogenic forcing, we make the following forecast: over the next decade, the current Atlantic meridional overturning circulation will weaken to its long-term mean; moreover, North Atlantic SST and European and North American surface temperatures will cool slightly, whereas tropical Pacific SST will remain almost unchanged. Our results suggest that global surface temperature may not increase over the next decade, as natural climate variations in the North Atlantic and tropical Pacific temporarily offset the projected anthropogenic warming.

Here is Latif again in quotes. He later challenged the Daily Mail’s interpretation of what he meant.

Daily Mail – 11 January 2010
Professor Latif said:
‘A significant share of the warming we saw from 1980 to 2000 and at earlier periods in the 20th century was due to these cycles – as much as 50 per cent.
‘They have now gone into reverse, so winters like this one will become much more likely. All this may well last two decades or longer.
‘The extreme retreats that we have seen in glaciers and sea ice will come to a halt. For the time being, global warming has paused, and there may well be some cooling.’
http://www.dailymail.co.uk/news/article-1242202/Could-30-years-global-COOLING.html

He did say previously….

New Scientist – 9 September 2009
“People will say this is global warming disappearing,” Mojib Latif told more than 1500 climate scientists gathered at the UN’s World Climate Conference in Geneva, Switzerland, last week. “I am not one of the sceptics. However, we have to ask the nasty questions ourselves or other people will do it.”
http://www.newscientist.com/article/mg20327254.000-world-will-cool-for-the-next-decade.html

What I want to know is this – why is he concerned about asking “nasty questions”? He and the delegates should be jumping with joy. But as you know this is not what it’s all about.

James Abbott

jim Steele
The point still stands. You clearly state, derived from your view on the models, that
“any attribution of warming due to CO2 is at best unreliable and at worse a graphic fairy tale.”
That is a completely unscientific and unbalanced statement and when such appears in a paper it tends to undermine everything else in it.
You go on to ask
“I still await your constructive criticisms that provide a better scientific explanation from which a more informative debate could ensue.”
A few points on that:
Given the complexity of the system it is often difficult to explain local or regional changes and that gets even harder looking further back as obviously the records tend to become more fragmented and less reliable. Even now we are seeing record high ice area in the satellite record around Antarctica. That is a regional observation which on the face of it shouts “cooling” but cannot be extrapolated globally – Arctic sea ice is running well below average and NOAA has just reported a record warm global ocean temperature for May. So looking back at the stated Arctic warming in the decades before WW2 is not going to tell us a lot about global temperature.
Globally, the changes observed prior to the mid C20th, and those “observed” using proxies back for one or two millennia, can be accommodated within natural variation forcing but the post-1960s warming is outside the range seen in that period.
http://earthobservatory.nasa.gov/Features/GlobalWarming/page3.php
The warming seen in the last half century or so is also consistent with that which would be expected by the rising concentration of CO2 in the atmosphere. Natural forcing operating on a global scale may have contributed part of the warming, but cannot account for it all.
There is a lot yet to learn about our climate system so your statement of absolutes is not credible. Its as daft as saying that ALL recently observed climate change and extreme weather is down to CO2 induced warming. Clearly its not.
The trick is to try and draw out the underlying trend from the natural variations. The super El Nino of 1998 so much used and abused to try and show that warming stopped then is nevertheless a key reference point. We are currently close to record warm land/ocean globally yet with still broadly ENSO-neutral conditions and a fairly quiet Sun.

Ulric Lyons

” So the next few decades should provide the evidence needed to settle much of the climate debate. If natural cycles are indeed the climate control knob, the next 2 decades should witness a cool phase of the AMO”
I would say that the AMO will see a continued warm phase, because we can expect more negative North Atlantic/Arctic Oscillation conditions with weaker solar activity, and it is under negative the NAO/AO phase that poleward ocean transport is increased. The AMO should be inverse to the solar cycles, like through previous warm AMO phases:
http://www.woodfortrees.org/plot/esrl-amo/every:13/normalise/plot/sidc-ssn/from:1850/scale:0.5/normalise
During the dominantly positive period of NAO/AO preceding 1995, UAH shows the Arctic ocean cooling: http://snag.gy/mfOI7.jpg
No IPPC models predict any increase of negative NAO/AO states with increases in GHG forcing, and most predict increasingly positive NAO/AO conditions with increases in GHG forcing:
http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch10s10-3-5-6.html
Arctic amplification doesn’t exist, the polar opposite does.

James Abbott says:

“Arctic sea ice is running well below average…”
No.It’s not “well below”, and we’ve only got about 20 years of good records.
“…and NOAA has just reported a record warm global ocean temperature for May.”
Again, a measurement which has only been available with any reasonable quality for a short time (about a decade since ARGO came on line) and the temperature change is quite small, on the order of hundredths of a degree.
“…but the post-1960s warming is outside the range seen in that period.”
No, it isn’t. It’s an almost precise duplication of the pattern which existed well before CO2 concentration could have had any effect. Proxy records are of dubious quality, they cannot capture sharp movements, and the error bars are huge.
“The warming seen in the last half century or so is also consistent with that which would be expected by the rising concentration of CO2 in the atmosphere.”
The current 18 year-and-running halt in temperatures is inconsistent with the hypothesis that atmospheric CO2 is a dominant control knob.
“We are currently close to record warm land/ocean globally yet with still broadly ENSO-neutral conditions and a fairly quiet Sun.”
The time constants are long, and it takes time. But, the current trend is down.

James Abbott:
re your post at June 27, 2014 at 12:44 pm.
Global warming stopped more than 17 years ago. Face that reality. Accept that reality. Embrace that reality. It is reality.

Richard

James Abbott

Bart – looks like you will find a way round any data set to try and prove a pre-determined position.
richardscourtney – reality is that the current pause has lasted 12 years, not 17 and good scientific principles say that assuming there will be no further warming after such a relatively short time is untenable.
As to your “deprogramming” jibe, as I have posted before it is only in the last decade or so that the polarised skeptic/warmist debate has become so entrenched and on a quasi religious basis. There was no such nonsense back in the late 1970s/early 1980s when we studied atmospheric physics at university.
