Now Gluckman wants evidence too

Sir Peter Gluckman

How quickly the climate debate changes

From the Office of the Prime Minister’s Science Advisory Committee comes an announcement with the heading:

Release of an important report on the relationship between evidence and policy formation

It begins:

One of the key challenges for all governments is how to make the best use of evidence in both policy formation and policy evaluation.

It’s reassuring to hear that the PM’s science advisor is prepared to look for evidence. At least in relation to global warming, it’s not an instinct he’s been noted for. He tells us he’s released a report, Towards better use of evidence in policy formation, and I’d like to read it.

Until I do, I would remind Sir Peter that evidence is required to establish the following key factors in the global warming debate — evidence that has not surfaced so far. We have been looking for evidence to show:

1. The existence of a current unprecedented global warming trend.
2. That the greenhouse effect is powerful enough to endanger the environment.
3. A causal link between human activities and dangerously high global temperatures.
4. That climate models have a high level of skill in predicting the climate.
5. A causal link between atmospheric levels of carbon dioxide and global temperatures.
6. A causal link between global warming and the gentle rise in sea level.

That will do for now; there is more.

Since a lot of policies have already been chosen in the absence of this evidence, we look forward to hearing Gluckman’s recommendation to the Prime Minister to cancel, halt or suspend the relevant policies until the relevant evidence is discovered.

Now, since that’s perfectly scientific, just as Gluckman says, it can’t be too much to hope for, right?

Perhaps Sir Peter Gluckman would be interested in this evidence:- Greenhouse Gas Theory Discredited by ‘Coolant’ Carbon Dioxide Apr 14, 2011 John O’Sullivan Professor Nasif Nahle found something deeply troubling about the man-made global warming theory (AGW). He explains, “I started out wanting to debunk those deniers of science.” Nahle had originally believed that human emissions of carbon dioxide (CO2) were warming the atmosphere until he found an incorrect assumption within the greenhouse effect hypothesis. Invited to attend a televised debate on the Indonesian Tsunami that addressed whether global warming was a factor in that catastrophe, Nahle checked the validity of calculations relating to the combined reactions of certain atmospheric gases to solar radiation in the so-called greenhouse effect. “That was when I saw it was junk science.” n his new paper, ‘Determination of the Total Emissivity of a Mixture of Gases Containing 5% of Water Vapor and 0.039% of Carbon Dioxide at Overlapping Absorption Bands’ the Mexican biologist turned climate researcher proves that in nature, CO2 and water vapor mix together to decrease infrared radiation emissions/absorptions in the air. This is the opposite of what conventional climatology has been saying for years.… Read more »

It would appear that a certain Mr Renowden wishes to play “whack-a-mole” with you Richard, convenor of the “climate clueless” to use his turn of phrase.

Personally, I am more interested in locating those 50 million climate refugees. After returning to a cold and depressing Christchurch from a week in Aussie, that story has got me rolling in the aisles.

Thanks Andy, I’ll check him out later, too. Maybe on Wednesday. I don’t suppose he offers any evidence, does he? Nor would he know about the 50 mill refugees? Nah, didn’t think so. Funny how asking for facts gets the climate deniers’ blood going. Not their brain, just their blood.

It’s curious how quickly he turns to insults, yet I don’t remember insulting him. Not ever.

There was an extensive, often acrimonious discussion on Judith Curry’s blog in a 3 parter about “Slaying the Sky Dragon”, with numerous posts by Nasif Nahle in Part 1.
Following the usual dismissive and sneering insults from commenters claiming the academic high ground, he seems to have dropped out of the subsequent parts (though does get a mention in dispatches)

Yes he does supply some “evidence”. CO2 levels are increasing, and because it is “obvious” that CO2 causes warming, it is “obvious” that we are warming the atmosphere due to fossil fuel burning.

Jim “Death Trains of Coal” Hansen is touring NZ in May (at the invitation of various Green organisations) to help lobby against the Southland Lignite mining.

Maybe we can ask him for evidence. I don’t see Jimbo’s tour extending to the West Coast. It would nice to show him some of the original Death Trains that powered the early Coast economy., maybe meet some of the local Death Train operators.

50 million climate refugees can’t be wrong. Renowden: “More CO2 means more heat retained in the system” Really? Where is it? Trenberth can’t find it, the “causal link” has been broken for the last decade and besides, Ferenc Miskolczi and now Nasif Nahle pour cold water (or should that be water vapour) on the notion. Cook (scepticalscience): “More heat returning to earth”. [Huh?] I think he means LWIR although that just removes the “human fingerprint on climate change” because there’s no heating ability in that except maybe in the early hours of the morning when some earth materials might have cooled to a level where the LWIR can slow further cooling before the sun takes over again and even that is land only – not oceans, lakes or rivers.. But it’s about rate of heat loss – there’s no heat gain from GHG’s. What a gold mine that post is. I wish I had more time right now to give it the attention it deserves but it’s saved to my local drive for future reference (and in case it goes missing – like the heat – and the refugees). Just one question each… Read more »

I’d mention Gluckman’s frequent references to Pielke Jr’s “The Honest Broker” in the pdf.
To the committed warmista, Pielke’s name is mud (he ;proposes amongst other things that most countries energy and climate policies are pure fantasy)

I haven’t read The Honest Broker, but I have read his more recent book The Climate Fix.
Prof Gluckman is asking for feedback, so I might have to write to him on this latter topic.
I personally feel that everyone involved in climate policy should read Pielke’s books.

I found this old comment from Gareth re. Pielke Jnr.

Given that their new found friend Peter Gluckman is so fond of RP Jnr, this is telling.

Pielke Snr and Jnr would like to think they have credibility, but in reality they’re a long way from the mainstream. Jr’s piece reads like an attempt to be deliberately controversial, to garner some media attention for himself as an “honest broker”.

I think he’s a long way off the mark, because he confuses the WattsUp and anti-green noise with serious science. He is right in one sense — that the debate should be about targets for emissions reductions, but he dives deep into his policy collapse schtick before making any cogent argument about why 450ppm is unrealistic.

In the context of US politics, it also seems directed at undermining whatever policy consensus Obama is trying to pull together. By saying it’s too hard, he prepares the ground for all those who want to do as little as possible. He has been positively Lomborgian in the past in his attempts to downplay the real message coming from climate scientists.

Gareth’s Plan B for sea level rise now that thermal rise (Plan A) is not working out so well is that the Antarctic and Greenland ice sheets are melting faster than estimated and have been releasing 475 gigatonnes of melted ice into the sea each year and the rate has been accelearting since 2005. All this extra water “could” push global average sea level 6 inches higher by 2050, apparently.

http://www.ess.uci.edu/news/washpost201103

Problem being that the accelerating melt has produced a decelerating sea level rise – I hope Gareth has a Plan C. Data here for anyone wanting to plot it.

Ron, I had a quick look at the Part 1 thread, Nasif Nahle sure is fiesty but I don’t think it’s the right approach given JC’s forum.

It is fascinating how Nasif being Mexican is so much more in tune with heat than some of the others from his experience in 40 C daytime and 30 C nighttime that can last for days. One of the others (possibly a warmist) was unable to conceive that the human body could even adapt to those temperatures.

This post and a few others but starting with a Mike Palin comment at HT got me thinking about an easy way to differentiate the solar SW heating effect from GHG LWIR’s comparative inability. I would appreciate some feedback on this because I have not thought it through properly yet and I might be wrong. The basic misconception I see in backradiation discussion is that GHG’s “heat the earth”. This misunderstanding is evident in Gareth’s HT post in reply to the above post here although Gareth tends to stick with “more energy (or heat) in the system” but he has used a scepticalscience graphic that shows “more heat returning to earth” in his post. The difference could be communicated using the question: What burns the skin on a sunny day, the sun or CO2? No-one is slip, slop n slapping to protect themselves from GHG LWIIR because it is solar UV that does the damage. So if LWIR does not penetrate water more than a few nanometers and it does not burn skin, the possibly that it could add heat to rock, sand, earth, concrete, roofing etc already containing heat (Q) from the… Read more »

This is the key part of the interview with respect to this post:

PAUL How can we be so sure, tell the people at home again, how can we be so sure that climate change, or current climate change is human induced?

SIR PETERI think that there is no other explanation possible for the rate of change in carbon dioxide and other greenhouse gases in the atmosphere, there’s absolute lots of evidence that humans are degrading the planet in many ways, and the modelling and the analyses make it very clear that human activity is responsible for the way of the change in the planet.

OK, we seem to be in circular reasoning mode again. CO2 causes global warming, CO2 is increasing, therefore CO2 must be causing global warming. What’s more, our models, that are hard-wired to CO2 forcing, back this up (with a bit of tweaking). Furthermore, the “environment is being degraded”.

Is it any wonder that we get sceptical?

First save the file as a .txt to your hard drive. Then from Excel, choose a blank sheet and Choose Data | From Text (Excel 2010). If you’re not using Office 2010, you may have to use Help to find out how to import data, I’ve forgotten the exact menu commands to use.

Anyway, once you click From Text, you choose the .txt file you saved earlier, and follow the Text Import Wizard dialog. It’s quite useful, you can specifiy Delimited or Fixed Width, etc., and it shows you the effect of your choices on the data in the file.

Another blow to warmist theory: Decreasing radiation from greenhouse gases Saturday, April 16, 2011 The anthropogenic global warming theory is based upon the notion that increasing ‘greenhouse gases’ will increase infrared ‘back-radiation’ to the earth to [supposedly] warm the planet. The theory also claims that increases in the minor ‘greenhouse gas’ carbon dioxide will cause increases in the major ‘greenhouse gas’ water vapor to amplify the infrared ‘back-radiation’ and global warming. A study published online yesterday in The Journal of Climate, however, finds that contrary to the global warming theory, infrared ‘back-radiation’ from greenhouse gases has declined over the past 14 years in the US Southern Great Plains in winter, summer, and autumn. If the anthropogenic global warming theory was correct, the infrared ‘back-radiation’ should have instead increased year-round over the past 14 years along with the steady rise in atmospheric carbon dioxide.

I’ve got my wires crossed, 1.7 W.m2 is as this quote from Dr Roy Clark’s “A Null Hypothesis for CO2” not 2xCO2 (sorry folks)

Over the last 50 years, the atmospheric CO2 concentration has increased by 70 ppm to ~380 ppm and the average annual sunspot index has been ~70% above its historical mean from 1650.1-3 During this time, ocean temperatures have increased, Arctic sea ice extent has decreased and the average meteorological surface air temperature has increased.4-8 Under ideal clear sky conditions, the 70 ppm increase in CO2 increases the downward atmospheric long wave infrared (LWIR) surface flux by ~1.2 W.m-2. This goes up to ~1.7 W.m-2 for the full 100 ppm anthropogenic increase over the last 200 years. These numbers are derived from radiative transfer calculations using the HITRAN database and are used as ‘radiative forcing constants’ in
the IPCC climate models

Doug Proctor says: April 21, 2011 at 9:24 am CO2 “warming” means that all heat in the oceans and non-oceanic surface comes from a downward heating of a warmed atmosphere. The speed with which heat penetrates 750 m into the oceans from a contact (and wind/wave turbulence) seems unlikely. After all, the air over the sea has warmed only 0.23C or so since 1979. If it were the sun’s rays, as they penetrate >60m and are powerful, seems more reasonable. A 50 ppmv increase in pCO2 at 3.75 W/m2 is 0.51 W/m2, meaning that at the end of the rise there is a 0.51 W/m2 increase in power, while an AVERAGE increase of 0.25 W/m2. This is on top of a current atmospheric absorption (clear skies) of 68 W/m2 and a land/sea absorption of 236 W/m2. Those of us who have swum in Northern lakes during 35*C summers know how thin the warm water is all through summer. Heat doesn’t want to go down. But apparently 0.25 W/m2 of warming by CO2 over the last 30 years flows through and is obvious beyond a 68 W/m2 clear air absorption and 236 W/m2 substrate… Read more »

Sir Peter Gluckman’s attitude to climate science is a bit of a worry. For a ‘top scientist’ ( the term has become somewhat suspect since some person or persons unknown relased that batch of emails from the UEA’s electronic files) to only now begin looking for evidence to support his prior statements and beliefs about global warming seems somewhat ass-backward to me. Merely reading the list of failed doomsday prognostications from the CAGW believers and promoters should be enough to raise some doubts. A quick glance at some of the 900-odd peer-reviewed papers that demonstrate that the sceptical arguments have merit should be compulsory reading for advisors such as Gluckman. I suspect his advice to be thinly-disguised advocacy for a fashionable perspective rather a scientific one.

Peter Gluckman is a medical researcher. He’s a good one, so he hasn’t been splitting his time reading up other people’s disciplines, or running a climate model in his spare time.

He knows no more about atmospheric physics, solar activity, coupled models, paleo-climatology, forecasting, oceanography, glaciology, etc than your average medical practitioner.

When he lectures the NZ public on climate predictions he speaks with zero authority. He can say no more than ” a guy told me that a girl wrote an article about another guy whose computer said this might be true.”

And this is equally true of speeches made by all those faculty deans, colleges, institutes, Royal Societies, and other science trade unions. And green activists and politicians. It’s all just hearsay ramped up by rhetoric and a little imagination.

If you don’t know who Bob May is, I strongly advise you do some googling. A New South Welshman of the small, nuggety type, he is one of the most brilliant minds of our generation; one of very few physicists who made a successful transition into biology, and virtually single-handedly invented the field of mathematical epidemiology (my speciality).

We, therefore, have the first explanation on the overheating of the Tungsten filament: It is not warmed up by a colder system inside the bulb, but by IR quantum/waves reflected towards the Tungsten filament by the “special coating” covering the inner surface of the paraboloidal integrating mirror bulb. Now, does the Tungsten filament have the ability to absorb the reflected IR quantum/waves and reach a higher temperature?

Doug, here’s the “Lite” version of the reply I tried to post. I’ve broken it up and a continuation is posted at the Easter thread (link at bottom) where I have posted a series of Nasif Nahle articles that deal with the deficient physics of AGW and some concepts relevant to your points and my reply here. A 50 ppmv increase in pCO2 at 3.75 W/m2 is 0.51 W/m2, meaning that at the end of the rise there is a 0.51 W/m2 increase in power, while an AVERAGE increase of 0.25 W/m2. This is on top of a current atmospheric absorption (clear skies) of 68 W/m2 and a land/sea absorption of 236 W/m2. The increase in “power” is not what it seems. To use an electrical analogy, LWIR downwelling radiation is “apparent” power – not “real” power. Equal fluxes of solar SW radiation and LWIR backradiation will not yield the same heating effect on a specific material (say water) due to the different wavelengths (i.e what part of the spectrum the respective radiation is propagated). If it were the same, the LWIR energy could be harnessed at night for electricity generation purposes in… Read more »

Thank you for your time and thoughts. It is distressing but not all that surprising that W/m2 equivalent has not the same effect as W/m2 real and so forth. This is the reason that the warmists and others say we should listen to authority, not determine things ourselves, that they are experts and know, and we are amateurs and know not. I and others look, primarily, for internal inconsistencies. I agree that numerics cause the readers to glaze over, but words and thought arguments by themselves have too much slop to be definitive. It is only when we find that A + B does not equal C as posited that the error in others’ thinking is proven. I’ve tried to stay within conventional argument, as in the OHC, to see if the numbers cross-check. I find or I feel a disconnect. The IPCC and others use power equivalents for CO2, specifically 3.75 W/m2 for a doubling of CO2. If true, then the increase in recent CO2 has this “power” since 1980 of about 0.25W/m2, average.

Doug, this following quote from your comment illustrates perfectly what I was getting at (I’m not disagreeing, just coming from a different angle). The concepts, principles, laws, rationales, assumptions, etc have to be valid for the application and communicable and consistent (as you say) in words or diagrams BEFORE the numerics are applied. It’s pointless moving on to numerics if the rationale is flawed in the first instance (the qualification) but if the reasoning is OK, THEN apply the numerics (the quantification). If the concept is faultless, those who are not numeric will be won over by the qualification but there will always be those that require the quantification also. From your comment:- Given that, with the AGW meme, we are transferring energy from the atmosphere into the ocean (and land masses), then we can ask ourselves if the thermal gradient and the infra-red re-radiance that is actually going on can, reasonably, penetrate that far and that deep that fast This AGW reasoning is flawed on so many levels that I despair every time I see it (its wrong intuitively if nothing else).

It Is Impossible For A 100 ppm Increase In Atmospheric CO2 Concentration To Cause Global Warming Dr Roy Clark Overview Anyone who tries to understand how a 100 ppm increase in atmospheric CO2 concentration causes climate change will soon find out that the entire global warming argument is nothing more than empirical speculation. No cause and effect linking CO2 and global warming has ever been demonstrated because none exists. In order to understand how the Earth’s climate works it is necessary to go back to first principles and look carefully at the surface energy transfer. The air-ocean and the air-land interfaces behave very differently, so they have to be considered separately. This article summarizes the work performed by Dr. Roy Clark, the founder of Ventura Photonics, on the underlying energy transfer physics that sets the Earth’s surface temperature. However, first we must define the energy transfer question that we seek to answer. Ask the Right Question Over the last 50 years or so, the atmospheric CO2 concentration has increased by about ~70 ppm and over the last 200 years this increases further to ~100 ppm. Under ideal ‘clear sky’ conditions, these increases in… Read more »

Bob, fixed width is the answer (didn’t occur to me to try that). Thank’s for the “Dummies” tutorial.

I often miss the simple way just because I don’t make time to work it through – then I take the obtuse option. Until now my best method was to run the file through my EMD program (strange but true).

This is so handy because all the other US data is in the same format too e.g. ice core, GCM initialization parameters.

I placed a 3rd order polynomial trend on the Global Mean Sea Level and it shows a pronounced deceleration after about 2004. 2004 is when OHC turned from rising to falling. The (by one account at least) accelerating Greenland and Antarctic ice sheet melt since 2005 is supposed to be adding to sea level rise (catastrophically).

Would it be correct to say that steric fall is over-riding eustatic rise (if there is any)?

I have to concede though, that starting the plot at 2005 does return an accelerating rise using the same polynomial but the data from mid 2009 onwards bucks that trend.

NASA keeps mum on data that could disprove anthropogenic global warming theory Saturday, April 23, 2011 The theory of anthropogenic global warming is based upon the notion that increases in the minor greenhouse gas CO2 result in increases of the major greenhouse gas water vapor, thereby supposedly increasing global warming to alarming levels of 2-5C per doubling of CO2 levels. Without this assumed and unproven positive feedback from water vapor, there is no basis for alarm. While the IPCC confidently stated in their 2007 report, “The average atmospheric water vapour content has increased since at least the 1980s over land and ocean as well as in the upper troposphere. The increase is broadly consistent with the extra water vapour that warmer air can hold.” a 2005 paper based on the NASA water vapor data set [called NVAP] showed that water vapor levels had instead declined (with 95% confidence) between 1988-1999. The paper states, “By examining the 12 year record [1988-1999], a decrease of TPW [total precipitable water vapor] at a rate of -0.29 mm / decade is observed. This relationship is significant at the 95 % but not at the 99 % level… Read more »

A very constructive challenge (not so) Silent. This could be in the form of a competition similar to one that was run here a while ago to come up with a parliamentary question. I will email Richard Treadgold with this proposal, maybe he will conduct it via a post. To get the ball rolling, my approach would be to keep it simple and to distill the issue to the one defining factor that either supports or disproves the theory of catastrophic anthropogenic global warming e.g. —————————————————————————————————————————— To Sir Peter Gluckman, The theory of catastrophic anthropogenic global warming relies entirely on the notion that increases in the minor greenhouse gas CO2 result in increases of the major greenhouse gas water vapor, thereby supposedly increasing global warming to alarming levels of 2-5C per doubling of CO2 levels. Without this assumed and unproven positive feedback from water vapor, there is no basis for alarm. The IPCC states in their 2007 report:- “The average atmospheric water vapour content has increased since at least the 1980s over land and ocean as well as in the upper troposphere. The increase is broadly consistent with the extra water vapour that… Read more »

Speaking of Chief Scientists, Jo Nova has some interesting observations on the apparent neutrality of the Australian CS Ian Chubb

http://joannenova.com.au/2011/04/is-it-possible-our-new-chief-scientist-has-doubts-about-climate-science/

At least, he (wisely) appears to be keeping out of the politics

From Tim Ball:-

Let’s counter the claim that CO2 has overridden all natural causes for the last 50 years. Only a couple of simple examples are necessary.

Figure 1 shows the change in Earth albedo produced by the Earthshine Project.

Figure 2 shows the plot of decreasing number of weather stations and global temperature.

Gareth Renowden plays whack-a-mole with a moth-eaten feather duster, Tim Ball uses a wrecking ball.

Richard C@99; I would add in respect of water vapor decline the Soloman paper:

http://www.sciencemag.org/content/327/5970/1219.abstract

The Paltridge paper:

http://www.theclimatescam.se/wp-content/uploads/2009/03/paltridgearkingpook.pdf

The Pierce paper:

http://meteora.ucsd.edu/~pierce/papers/Pierce_et_al_AIRS_vs_models_2006GL027060.pdf

Of possibly more interest is the fact that in the overlapping spectrum CO2 reduces the emissivity of H2O:

http://meetingorganizer.copernicus.org/EGU2011/EGU2011-4505-1.pdf

http://thesis.library.caltech.edu/2809/1/Lapp_m_1960.pdf

This is well shown in a graph of H2O and CO2 in the overlapping spectrums:

http://scienceofdoom.files.wordpress.com/2010/07/spectra-h2o-co2-15um.png

This decline in the emissivity of H2O in the presence of CO2 means the dependency of AGW on climate sensivity from positive feedback from H2O is severely restrained and must be problematic.

Ten Physics Facts – Setting the Record Straight Written by Hans Schreuder, guest post | April 26 2011 This is a rebuttal based on Physics Trumps Right-Wing Ideology written by Mr. Puckerclust. Puckerclust begins his post thusly: “Global warming deniers know as much about climate science as they do about brain surgery. Would you let them tell your doctor what to do about that tumor? “Why do I–a professional physicist and lifetime member of the American Physical Society–accept the reality of human-caused global warming? Because I accept the following top-ten list of physics facts, which have never been disputed in the scientific literature. This is also why the American Physical Society of 47,000 physicists says “The evidence is incontrovertible: Global warming is occurring”.” Before we set the record straight about those ten supposed physics facts, let’s also set the record straight on some preliminary information that Mr Puckerclust would like us to believe. (a) The APS statement on climate change was not drafted or confirmed by “47,000 physicists” of the APS, but by the APS council. (b) Many members of the APS have criticized the statement, incl. Harold Lewis who resigned in protest.… Read more »

Quite entertaining Puckerclust’s original essay ( I can’t help feeling there’s an awful ClusterF**k somewhere in that moniker)

A good deal of the “usual suspects” from the Denialsphere(tm) wade in with their tuppence. Mr PuckerClust does his best to bat them away but in the end he needs to implement a “moderation policy”.

Quite an entertaining read.

On the subject of “denial”, I see that John Cook’s new book is on Amazon (Of “Skeptical Science” fame) Climate Change Denial: Heads in the Sand http://www.amazon.com/Climate-Change-Denial-Heads-Sand/dp/1849713367 Product Description; Humans have always used denial. When we are afraid, guilty, confused, or when something interferes with our self-image, we tend to deny it. Yet denial is a delusion. When it impacts on the health of oneself, or society, or the world it becomes a pathology. Climate change denial is such a case. Paradoxically, as the climate science has become more certain, denial about the issue has increased. The paradox lies in the denial There is a denial industry funded by the fossil fuel companies that literally denies the science, and seeks to confuse the public. There is denial within governments, where spin-doctors use “weasel words” to pretend they are taking action. However there is also denial within most of us, the citizenry. We let denial prosper and we resist the science. The CSIRO also provide a similar review This book shows how we can break through denial, accept reality, and thus solve the climate crisis. The authors examine the nature of climate change denial,… Read more »

I can’t top that (must be a new D-word record surely), but I did stumble upon:-

Scepticism is bastardry, says head of ACF

THE president of the Australian Conservation Foundation has attacked the “scientific bastardry” of climate change sceptics amid weakening public consensus that humans are to blame.

And

He said the evidence for human-induced climate change was backed by virtually all scientists. He described the views of climate change sceptics as “illegitimate arguments that you could call scientific bastardry”.

Ian Lowe, who is also professor of science, technology and society at Griffith University, lamented the narrowing of the carbon tax debate.

http://www.theaustralian.com.au/national-affairs/scepticism-is-bastardry-says-head-of-acf/story-fn59niix-1226046544056

Lowe profers this wisdom in the Cook book editorial reviews:-

‘Climate Change denial is the biggest single obstacle to achieving a sustainable future. This book provides all the evidence and arguments you need to counter the campaign of misinformation. Read it, study it and spread its message widely.’

I wonder what the D-word count is for the entire Cook book?

US$23.84 seems excessive for pulp fiction.
