The graphs probably need to be updated, incorrect accounting for post glacial rebound is probably doubling the figures given there! -

cruzn246 #36: As usual, you seem to be basing your conclusions on fiction. "The carbon data is all over the place clearly showing the Little ice age big time, but hockey stick Mann claims it wasn't a NA event. Please." Mann doesn't say that the LIA was a non event. It is very clearly evident in the Mann 2008 reconstruction;"WHY? Are they afraid to show what happened with carbon 14 after that? I would say yes." Congratulations, your official wacky conspiracy theorist tin foil hat is in the mail. Carbon 14 ratio was a reasonable proxy for solar irradiance prior to the point that we started putting tons of fossil carbon into the atmosphere and releasing bursts of radiation with atomic explosions. Of course, we've been able to measure solar irradiance directly for decades so we don't need proxies any more. We've been in a pronounced solar minimum for a few decades now... while temperatures have been going through the roof. "I know this is not a carbon 14 measure, but this closely follows the same of pattern carbon 14 readings." Ummm... what? They aren't even close. Total atmospheric carbon levels barely changed at all between 1000 AD and 1800 AD while Carbon 14 ratio was going up and down like a roller coaster along with TSI. Since then total atmospheric CO2 has risen at a steadily increasing rate while Carbon 14 has continued to roller coaster.

Falcon3155 at 19:04 PM on 28 September 2010Is Greenland losing ice? (psst, the answer is yes, at an accelerating rate)
The article fails to mention that a new paper, Wu et al. (2010), has concluded that that losses have not in fact accelerated as claimed. Although the ice-sheets are losing mass, the losses estimated by the authors represent less than half of the other GRACE-based estimates, which undermine the collusions the four papers cited in Wray's article. Wu et al. conclude that "a significant revision of the present estimates of glacial isostatic adjustments and land-ocean water exchange is required". Reference: Wu et al (2010) "Simultaneous estimation of global present-day water transport and glacial isostatic adjustment" Nature Geoscience 3, 642 - 646 (2010)doi:10.1038/ngeo938 (Link to www.nature.com) -

archiesteel #125 Ned and I did some forensics on BP's failed statistical analysis (i.e. would get him a fail grade as a first year university assignment) in this thread. We determined that the analysis suggested that if his estimate of the urban heat island effect was reasonable (and it's far more likely to be an overestimate - but we can't say if it is or by how much because he hasn't released his methodology) then his estimate for climate sensitivity is bang-on 3 degrees Celsius once corrected for the urban heat island effect. Which is entirely consistent with the mainstream climate science estimate. BP's current tangent appears to be a variant of the 'models are inaccurate' argument. It seems to me to be without merit as it uses the "if we can't know everything then we know nothing fallacy. -

#127 Riccardo at 16:44 PM on 28 September, 2010 So, although it is indeed relevant for clouds (fractal or not), it's not for water vapour. In case of water vapor radiative properties in the thermal IR range it is not scattering, but absorption and emission. Let's consider a thin horizontal slab of air loaded with a fixed quantity of some "greenhouse gas" (one which has a nonzero absorptivity in thermal IR). For the sake of simplicity let's suppose absorptivity is independent of frequency in this long wave range (the stuff is "grey" here). Let molar density of this GHG along the surface of slab be d(x) where x is any point on the surface of the slab, expressed in mole/m2 units. Integral of d for the entire surface is clearly the total quantity of stuff, so it is constant as it is said before. However, otherwise d is allowed to vary along the surface. Opacity at point x is clearly 1-e-c·d(x) with some positive constant c. If |c·d(x)| is small everywhere (absorptivity of stuff is not too high and/or the slab is thin), second order approximation of it is c·d(x)-1/2·c2·d2(x). Overall specific opacity of the slab can be calculated by integrating this expression along the entire surface and dividing by area. Integral of first term being proportional to average molar density, as long as the second term is negligible, you are right, only the quantity of stuff counts, not fine details of its distribution. However, as soon as second moment of d gets significant (distribution is "rough"), it is no longer true. You can also see that integral of the second term is always positive, therefore if it's got subtracted from integral of the first one, specific opacity is always decreasing. It's also possible that second order approximation is not good enough. In this case higher moments of distribution also come into play. Specific opacity is a nonlinear (concave) function of molar density, so departures from uniform distribution tend to decrease opacity. For well mixed GHGs it is not an issue, but water vapor is not one of them. -

No Argus. It's fortunate that we live in the times that we do with all the advantages of scientific instruments unimaginable to earlier generations. It's worth reminding ourselves of that from time to time. It's not just dentistry and antibiotics that make this a good time for us. There's a whole infrastructure of scientific endeavour which we don't bother to look at most of the time. When we need it, it's there. -

"Fortunately we have empirical observations against which we can test these requirements." Somehow I stopped to think about the connotation of this sentence from the prolog. Question: Why is the word 'fortunately' appropriate in this context? (a) Because it is such a joy to be able to 'debunk' all skeptic arguments? (b) Because it would be terrible if somebody holding opinions other than ours would ever be right, plus it would be so embarassing if main stream climate scientists were ever wrong?? (c) Because if our climate was governed by outer space, there would be nothing we could do about it - now, all we have to do is stop burning coal and oil? (d) Because of other reason (please specify!) (Check one) -

Hilariously, Anthony Watts uses the above guest post as an example of John Cook 'embarassing' himself. Watts 1. Uses a misquote of Mr Cook from Sourcewatch to impune John's scientific credentials. A quick Google would have revealed that the SW quote was wrong or out of date. Each of his points is quickly debunked by a search of SS. Quality journalism! 2. Posts a link to the wrong article - he wanted to link to New Scientist on solar, he linked to Nature on Ocean Cycles. 3. From the tone of the original article it is clear he believed the guest post was by John Cook, he later resiles from this once it is pointed out, harrumphing instead about blog owners being responsible for their content. 4. Complains that this guest news roundup is not 'peer-reviewed science'. Straw Man, the science here IS peer-reviewed, nobody claims or expects news and editorial to pass a review process. 5. Doesn't like the word 'denier'. Ho hum. Some people, not me you understand, might find the hilarious string of gaffes rather more embarrassing to the gaffee than his target...... -

nealjking at 17:45 PM on 28 September 2010Positive feedback means runaway warming
hadfield: This article is intended to illustrate a mathematical fact, not to describe the dynamics of the real atmosphere. Please read the Note that has been there from the beginning: "Note: This model incorporates a number of features of the actual feedback mechanism for the enhanced greenhouse effect, in particular the dependence of radiative forcing on the logarithm of CO2. However, it is definitely not intended as a full model for the effect. It's only intended to illustrate the point that there is no contradiction for a system to have positive feedback, while maintaining self-limiting behavior. " -
Riccardo at 16:44 PM on 28 September 2010The Big Picture (2010 version)
Berényi Péter, the fractal structure (if any) is irrelevant as far as absorption and scattering are concerned. The different scattering properties of a uniform vs an unven distribution of particles is due to a concentration effect which, at some point, starts to produce multiple scattering. Even an uniform distribution may produce multiple scattering if concetrated enough. So, although it is indeed relevant for clouds (fractal or not), it's not for water vapour. Unless you call water vapour micron size water droplets. -
scaddenp at 16:39 PM on 28 September 2010We're coming out of the Little Ice Age
As I stated, my comments about what the natural trend should be were from 1975 to now. However the figure I referenced shows the natural forcing from 1900. If you are trying a "its the sun" argument, argue it in the right place but also note all the detail there about it isnt. You wont find a C14 past 1950 that can tell you anything about solar - the atmospheric nuclear test regime overprints everything else, but now we have direct measurement of TSI anyway. Please try to stick to peer-reviewed science - that way you avoid the people who trying to fool you. -

#122 Riccardo at 08:18 AM on 28 September, 2010 The vertical distribution of clouds does matter, but it's another story. Water vapour concentration rapidly falls with altitude anyway. It's the same story. General shape of clouds is a fractal right because distribution of water vapor was like this in the first place before condensation started.It is this way in both lateral and vertical directions. If opacity is distributed unevenly in a medium, in most cases transparency is increased. You can see through a lattice, but can't do the same with a plate.

archiesteel at 15:50 PM on 28 September 2010The Big Picture (2010 version)
@BP, you have not presented a convincing case that climate sensitivity is lower than 3C. There is no strong indication that soot on snow, the UHI effect or ocean redistribution cycles are responsible for a significant temperature change (in fact, the UHI effect has tended to introduce a *cold* bias, not a warm one). Furthermore, you have repeatedly failed to address the criticism regarding your statistical analysis on a different thread. Until you at least attempt to clear your name, I cannot take anything you say at face value - if you can't admit making a mistake, then we can't assume that *any* of your analyses are correct. -

@cruzn246: "Well, with Venus you have a completely different situation. It's like comparing apples and oranges. That type of equilibrium, static, is next to impossible in our atmosphere system . We have what is called a dynamic equilibrium." Okay, now it's obvious you have no idea what you're talking about. "I'll ask you the question that Tom doesn't seem to want to answer. Naturally, without anthropogenic influence, should we be heating up or cooling now?" Cooling, most probably. The fact temperatures are still increasing tells you how large the anthropogenic influence is. "The funny thing is it really took off in the latter part of the 19th century. that pretty much coincides with the warm-up from that time till the mid 40s. It says the graph stops in 1950. WHY? Are they afraid to show what happened with carbon 14 after that? I would say yes." Are we back to conspiracy theories, now? The evil scientists are hiding the data, is that it? "I know this is not a carbon 14 measure" In other words, it is completely irrelevant. You just wanted to add a graph to give your innocuous post some credibility. -

Phila @ 37: 'Presumably, if you believe in "a loving God," you also believe in a God who gave us the ability to make intelligent decisions based on what science tells us about the world, and to take responsibility for our actions.' I absolutely concur. And 'scientism' represents human pride and its refusal to acknowledge our limitations as a species to which so many readers have eloquently alluded on this thread. 'Scientism' is not science any more than religiosity is religion. -

#118 KR at 06:32 AM on 28 September, 2010 modelled and empirical evidence indicates that the actual climate sensitivity is ~3°C for a doubling of CO2 It would be so if models would handle atmospheric water and turbulence properly (they don't) and if all the warming measured during the last several decades would be due to GHGs and none to soot on snow, UHI or ocean heat redistribution cycles. your increased inhomogeneity means lower local entropy, and is not a natural direction for the system to move in. Look again. It is not a closed system, but an open one, meaning there is a steady flow of energy through it. In such systems maximum entropy production is equivalent to minimum entropy contents under a wide range of conditions. Just consider the human body. You'll notice inhomogeneity in it on all scales, still, it is quite natural. At least as long as there is a steady flow of free energy through the system coupled to a high entropy production rate. Should the guy be starved to death or get suffocated though, homogenization of both body temperature and structure kicks in immediately. -

Folks, click on the basic tab above and look at the charts in the Limited History section. The carbon data is all over the place clearly showing the Little ice age big time, but hockey stick Mann claims it wasn't a NA event. Please. Note another thing. The LAST part of that carbon chart shows the highest levels of carbon 14! The funny thing is it really took off in the latter part of the 19th century. that pretty much coincides with the warm-up from that time till the mid 40s. It says the graph stops in 1950. WHY? Are they afraid to show what happened with carbon 14 after that? I would say yes. they then go to a lame sunspot cycle. This is not the same as a carbon measurement. Why the switch? Because if they would have continued with a carbon graph you would have seen something like this.I know this is not a carbon 14 measure, but this closely follows the same of pattern carbon 14 readings. If someone finds the chart for carbon 14 readings since 1950 I would sure like to see them.

cruzn246 - given the Milankovitch cycle (sp?), solar irradiance, and the fact that our CO2 emissions (which should add up to 4ppm/year) are adding 2ppm/year, it should be cooling now without anthropogenic influence. Next question? -
Doug Bostrom at 14:14 PM on 28 September 2010We're coming out of the Little Ice Age
Speaking of anachronistic climate patterns, personally I think throwing a substantial and irretrievable additional lagged input into a system dominated by hysteresis without thoroughly predicting the novel perturbation's effects is reckless. We're a little late off the mark with integrating our own activities with those of nature. Does our belated realization mean we should thus ignore our activities, remain fixated on natural phenomena, pretend we don't exist? Perhaps such a comment would better fit in the topic of models, however. -
cruzn246 at 14:02 PM on 28 September 2010We're coming out of the Little Ice Age
"I'll take a punt but you need to ask over what timescale so I will look at post-1975 out to now. For natural effects TSI very slightly down since 1975. Milankovitch forcings are obviously dependent on latitude but glacial cycle tracks NH effects which are very very slowly going down. Aerosols slightly up. Overall barely perceptable change with maybe some cooling. Of course this is in AR4 WG1, FAQ 9.2, Fig 1." So you think we should have stayed in about the same climate patterns we were having from the the 40s to the mid 70s? -

Chrisc at @32: "I would far rather a civilisation based on love and respect for one's fellow human beings preferably grounded in humble acknowledgment of our dependence on a loving God 'in whom we live and move and have our being' " And I would far rather a civilization based on friendly fairies, dancing elves, and happy talking bunnies, but that has no more to do with reality than your fantasy. The fact is that our unprecedented standard of living, our ability to determine our future, and even our ability to feed the billions of people on the planet are due to the relentless honesty of the scientific method (no matter how hard some individuals try to subvert it). adelady @33: "What's so different with this issue?"

chriscanaris: I would far rather a civilisation based on love and respect for one's fellow human beings preferably grounded in humble acknowledgment of our dependence on a loving God 'in whom we live and move and have our being' as the Greek poet Menander famously put it. Presumably, if you believe in "a loving God," you also believe in a God who gave us the ability to make intelligent decisions based on what science tells us about the world, and to take responsibility for our actions. What "scientism" is telling us, again and again, is that what we choose to do affects people and the environment in ways that are potentially irrevocable. I can't respect any ethics, let alone any religion, that ignores these facts, or posits some sort of supernatural "Get Out of Jail Free" card that will save us from the logical consequences of keeping our heads in the sand, and I hope you can't either. At this point in human history, it's very hard to see how one could "love and respect one's fellow human beings" without understanding, in scientific terms, how our actions are likely to affect them. Echoing Doug @36, we've got some growing up to do. -

This is not really a significant physical sciences mystery, it's now a behavioral puzzle. When I was in high school there was a fellow I think would've been unanimously elected as a model of responsibility and maturity for his age group, a person who not only got straight A grades in what was then the equivalent of AP physics and maths but also seemed to -understand- physics, was not just regurgitating his lessons. Did that stop him from rolling over his brand-new VW Thing at the gates of the school, ejecting 5 occupants who despite all of their intellectual wisdom did not have the visceral, animal connection to facts necessary for their seatbelts to have been fastened? Did this boy stop and check those belts, were his high spirits overridden by his cold facts? No, and no. We've got some growing up to do. -

Revenue under threat? That's where I get flummoxed. Revenue comes from profitable activity - any profitable activity. I just don't see why a large organisation wouldn't grab with both hands at new opportunities to make money hand over fist. They're very good at extracting subsidies from governments for their current activities, what's to stop them arm-twisting for even more subsidies for newer activities? I have a suspicion that for all their money, glamour and presumed sophistication, these leaders of industry are much like peasants who won't move from the sides of a seething volcano. They just can't see the opportunity for a better, more profitable, life with less danger. -

CBW, I'm not so sure. I think it's a continuing anti-elite (or something) strand in society. The Nobel Prize granted to Einstein was specifically chosen to avoid the controversy over relativity. People in cafes would challenge him over this stuff - people who had much less chance of understanding relativity at all than people have now of understanding the generalities of climate science. The sociological project would probably be more along the lines of delineating which particular kinds of ideas people find uncomfortable and how that affects them personally and their interactions with the wider society. (Why do people who live on the sides of volcanoes resist the idea that they'd be better off moving somewhere safer? And a million other topics.) As for the 'alarmist' stuff on climate disruption, I'm really interested in why this is so much harder than dealing with acid rain or the hole in the ozone layer. Those ideas and eventual solutions took some time, but raised nothing like this level of antagonism and resistance. What's so different with this issue? -

Venus is in a thermal equilibrium (i.e. it's temperature is stable), but it's the closest thing we have to Hell." Well, with Venus you have a completely different situation. It's like comparing apples and oranges. That type of equilibrium, static, is next to impossible in our atmosphere system . We have what is called a dynamic equilibrium.

GC - perhaps indeed. To clarify. You made this statement. "The first test of any paleo-climate reconstruction should be whether it portrays past climate in a plausible way. Any set of proxies that disagrees with history should immediately be discarded." The implication was that the papers you listed did indeed disagree with history. I pointed you to data, relevant to those papers which show you are wrong. The proxy record is consistent with history. Feel free to point to other papers and the historical records that invalidate them. I have no reason to think Alley's temp reconstruction for central greenland is substantially flawed. I am intrigued to know what historical records you have for central greenland to compare it with. -
The Asymmetric War on Climate Change: No Cause for Alarmism?
Getting back to the topic at hand, I find it really interesting that all of this meta-science is being done these days. The climate change "debate" has gotten so off kilter that it is actually a sociological/psychological phenomenon worth studying in its own right. That anti-science denialists have gained so much power in a civilization built upon science is a remarkable thing. That ideology now trumps reality is utterly bizarre. I will leave you with a quote from the patron saint of the conservatives, Ayn Rand: "We can evade reality, but we cannot evade the consequences of evading reality." -

Adelady @ 27: One of those early USSR famines was the result of dustbowl conditions very like the USA and Australian dustbowls. And for the same agriculturally idiotic reasons. More like war communism and deliberate forced requisitions of grain and produce coupled with forced collectivisation. The famines affected the 'black soil' regions of the Ukraine - arguably the world's richest agricultural land. -
The Asymmetric War on Climate Change: No Cause for Alarmism?
It's funny to read that some ascribe the pollution in the USSR to a lack of private ownership when the problem was a government that was not accountable to its people. Here in the US, private companies were rampant polluters in the 1950s, 1960s, and 1970s until they poisoned enough of the landscape (and the people who lived there) that people demanded protection via government regulation, and they got it. It had nothing whatsoever to do with who owned what, and everything to do with a accountable government. Unfortunately, in the case of climate change, by the time the people are up in arms enough to demand action, it will be too late to fix the things they are up in arms about. -
The Asymmetric War on Climate Change: No Cause for Alarmism?
I for one am perfectly happy to agree that the USSR's environmental (and agricultural) policies were a disaster. If we were talking about whaling, I suppose we could all criticize Japan. For women's rights, we can point to Saudi Arabia (and unfortunately dozens of other nations where misogyny is the norm). And so on. Unfortunately, on the issue at hand for this website (climate change) the USA is the worst offender, with a number of other Western countries vying for second place. If people are convinced that the free market will solve all environmental problems, then they should get on board with the market-based proposals for emissions reduction (cap-and-trade, or carbon taxes). Those are more closely compatible with a "small-government" worldview than the alternative approaches to dealing with climate change (complex and unpredictable regulatory oversight, or massive government-directed geoengineering schemes). -

apeescape (#43), It seems I misinterpreted your "link Dump". Please accept my apologies. Thank you Ned, once again. Scaddenp, it seems we are having communications difficulties. I will try to rephrase my arguments more clearly tomorrow when there is no Monday night football. While I am doing that, what is your opinion on Alley's temperature reconstructions for central Greenland? Plausible or not? -

Camburn, you've got it a bit backwards, 180 degrees really. In the P&J study salinity itself was derived from CTD: "Salinity was calculated from CTD conductivity, temperature, and pressure data and calibrated to bottle samples standardized with International Association for the Physical Science of the Oceans (IAPSO) Standard Seawater using the 1978 Practical Salinity Scale (PSS-78). Some interesting background information on conductivity-temperature-depth (CTD) samplers here, including dynamic dampness: Conductivity, Temperature, Depth (CTD) Sensors Photos of systems, deployment As to whether P&J employed "models" in their analysis, you probably ought to read more carefully, starting w/section 3 on page 10. The techniques described therein might be described as a model though it certainly does not resemble what most of us understand when thinking of that term. You're of course perfectly free to quibble over the semantic employment of "model" but if you've got a problem with the research you'd do better to show specifically how the authors' methods might be improved lest you convey the impression you're just saying "I doubt it." Fortunately P&J are exactingly detailed in describing their techniques so you should be able to understand and then tell us precisely where they've gone wrong, if indeed they have done so and you've got the skill to make productive remarks. -

One of those early USSR famines was the result of dustbowl conditions very like the USA and Australian dustbowls. And for the same agriculturally idiotic reasons. As for the famines. The comparison there would be with the Chinese who also had lunatic plans and devastating outcomes. And I'm personally convinced that North Korea's continuing failure to produce or acquire sufficient food for its population is similarly based on ideas that are so foolish that they are wicked. -

Adelady @ 4 The USA produced dust bowls - the YSSR several famines which killed many millions. Phila @ 14: The saying in Soviet era Poland was, 'We pretend to work, they pretend to pay us.' Not much responsibility for anything there. Yes there were some idealists but the society was deeply permeated by cynicism. Doug; Abstinence education - a touch off topic - yet I never cease to be amazed at the casual way in which people will entrust their safety to a thin rubber sheath which slips off eveer so easy and carries a 10% failure rate in field conditions.
