Camburn @25, Sorry for the late response, have been busy. After reading your response to others who have answered your question, I have reason to suspect the sincerity of your question, but for what it is worth I will also do so. Please read the following and references cited therein. Specifically, the ones found: here, here, here, and here. A consistent and coherent story. -

camburn 41. Surely if the records are kept night and day, spring to winter, el Ninos and La Ninas, rain and shine, high tide and low tide, these variations in humidity or insolation or precipitation or whatever are all taken into account. We've been measuring what we can. We've got more and more sophiticated and getting more and more measurements and at working out what those measurements tell us. But for global warming, what we do know is that there's a certain amount of energy delivered by the sun and we can measure that precisely. We also know how to measure what's being released at the TOA as outgoing radiation. What you're worrying about is where the energy that's not escaped through the troposphere is at particular moments. Most of it's in the oceans and we're doing our best to catch up with measuring that. What's in the atmosphere is measured pretty well in the large scale and over longer lengths of time. You're just asking for day by day accuracy and precision that just isn't yet available from the systems we've got. But we don't need that level of accuracy. My mum and her peers were able to produce perfect roasts, cakes, bread and scones with wood stoves that had no measuring devices at all. Most of us don't need the baby health nurse to tell us that our precious little one is gaining or losing weight. We can make perfectly reasonable judgments and decide on appropriate actions without pinpoint accuracy all day every day. -

Camburn #41 As well as more humid air containing more heat than less humid air, I'd also expect that air at low pressure contains less heat per unit volume than air at high pressure too. Given that there's a fairly close relationship between humidity and temperature anomaly (the graphs show humidity over time, but it's worth comparing the trend to a temperature anomaly plot over roughly the same time period), then your point seems to be valid and interesting. However, the interest here is that it seems to provide a visualisation confirming that your argument is incorrect. -

37.muoncounter This paper seems to link UHI with water vapour and identify an urban-specific diurnal cycle (based on the abstract). I wasn't really trying to counter what was written by you, or the references, rather just point out there are other factors involved in the mix. I now notice you mentioned some of them in your following posts. I'd still like to know if the research mentioned in John's article is really specifically a human fingerprint or just the fingerprint of a warmer world? -

This is an excellent article in many ways, but I have to shake my head when I read, "the public needs to understand that science cannot and does not produce absolutely precise answers." This is itself an extremely unscientific hope. Even only a cursory acquaintance with "political science" should make it absolutely clear: the public has -never- understood this -- and it has only been getting worse, not better in recent years. If we have to change this to get timely action on AGW, we are doomed. -
Camburn at 13:28 PM on 22 November 2010The human fingerprint in the daily cycle
kdkd: You are missing my point entirely. An anomoly, even within a spatial area, using temperature is not a valid climatic heat indicator. You would have to assume that the RH is constant, which in most areas it is not. Where I live, rh can be as low as 15% and as high as 99%. There is absolutely no pattern to the rh, and is not dependant on temperature. The heat content of the air at say 30% rh @80F is a lot less than 80%rh @80F. Do you agree with me on that? -
kdkd at 13:15 PM on 22 November 2010The human fingerprint in the daily cycle
#36 cont "When talking about climate one must think in terms of heat content. A temperature in a desert, @ say 100F, is not the same heat content as a temperature in the tropics of 100F." This argument is also fallacious. Aside from your clear confusion over the difference between temperature anomaly and temperature (the quote above should have referred to anomaly rather than absolute value), you are making the assumption that the temperature anomaly measured in the desert is being compared to the temperature anomaly being measured in the tropics. In fact what happens in practice is that we measure a mean anomaly for a given spatial area, and compare that at different points in time. So long as the sample of measures are reasonably consistent with each other for a given spatial area at the different times, there is nothing wrong with this. Procedures have also been developed to deal with heat island effects, and changes in station location to improve the validity of this approach. Do you have any more fatally flawed arguments for us to deal with? I'm trying to write something quite difficult at the moment, and the ease with which your arguments are demolished is nice light relief. -

Camburn #36 "by itself tho, [temperature anomaly is] a useless metric when talking about climate" A bit strong. Must be treated with caution would be a more temperate way of making your point. However (cherry picking so-called-sceptics excepted) generally we do not use temperature anomaly alone to examine climate, although it is a useful and reasonably valid measure that makes good intuitive sense. There. It would appear that as you want to throw the baby out with the bathwater, that your argument is not valid. -

#36: "A temperature in a desert, @ say 100F, is not the same heat content as a temperature in the tropics of 100F." Just for fun, which way would heat flow: from 100F desert air to 100F tropical air or vice versa? -

#28: "Particulate and pollution domes and changes in evaporation and hydrology processes" Indeed. But if we're looking for a human fingerprint, evaporation won't cut it. How do 'hydrology processes' know when the weekends are and what the weekday peak traffic hours are? And how does water vapor know to take Easter week off in Mexico? I had a reference that showed different weekly patterns in the Arab countries (Friday is the weekly low in urban CO2 in Kuwait City, compared to Sunday in Rome), but it has escaped my sieve-like filing system for the moment. But riddle-me-this: where does the 500 ppm CO2 from urban traffic eventually wind up? Can it be seen 'downwind'? Are there any temperature anomalies that follow that distribution? I'd love to see evaporation and clouds changing with traffic density, but I'm betting that's not happening. That's why I don't get the point of the graph you posted in 27; nor do I give what I think Camburn is hinting at -- atmospheric moisture as a 'metric' for heat content -- much credit as a 'human fingerprint'. I'll give you that particulates and NOx are probably factors, but if the folks that think the urban CO2 domes don't extend upwards more than a few hundred meters are correct, then neither do those exhaust products. I live near a freeway with heavy rush hour traffic; I have a fine coating of black dust on my front porch on a regular basis. Never had it analyzed, but I bet its full of particulates from car and truck exhaust settling out. -
Camburn at 12:49 PM on 22 November 2010The human fingerprint in the daily cycle
kdkd: The 2nd proposition. Temperature is not a useless metric in given circumstances. It, by itself tho, is a useless metric when talking about climate. A temperature anomoly is based on temperature data. That is a given. When talking about climate one must think in terms of heat content. A temperature in a desert, @ say 100F, is not the same heat content as a temperature in the tropics of 100F. Can we agree on that? If anyone knows of a temp base that includes heat content as part of the anomoly I am all eyes. -

kdkd at 12:04 PM on 22 November 2010The human fingerprint in the daily cycle
Camburn: I'm not really sure what your point is. Are you suggesting that temperature anomaly is not a measure of the relative energy content of a body of matter? Or are you just complaining that its sensitivity is relatively poor. The first proposition is absurd. The second proposition is valid, but it does not make it a useless metric, just that it should be triangulated for consistency with other data. -
The human fingerprint in the daily cycle
Camburn - What would you consider a reasonable metric when measuring climate? You have disparaged temperature, and changes in long term temperature averages (anomalies); what are the alternatives you propose? Top of atmosphere radiation balance? Perhaps ocean thermal content or stratospheric cooling? Or ocean acidification? Flora matter, perhaps plant zone changes? Ice balance at the poles and on glaciers (numerous links, all measures are declining, use the search box)? If you have issues with temperature, essentially stating that rising temperatures do not indicate climate change, it's upon you to state what changes you would consider valid measures of climate change. -

John can you just clarify why this is specifically a "human fingerprint"? As you point out water vapour is a very strong GHG. Increased water vapour (as shown in the graph below) is a product of a warmer world rather than specifically a human-induced warmer world. I'm guessing you consider most of the GHG effect is coming from water vapour? Just to emphasis the importance of water vapour I'm going to take a stab that the highest year in the warm nights graph (fig1) is 1998 and is a product of El Nino, the peak is there in the Tamino graph as well.I'm suggesting that the interpretation of this data goes way beyond what the actual data is telling us.

Hyperactive Hydrologist : "All data that has been funded directly or indirectly by the tax payer should be readily available to everyone." The problem isn't the generated data, the CRU has always made that available, the problem is the source data, that is owned by different nations. The UK isn't responsible for data licensing for say China or other nations. Also what if a government lends money for research that gives a UK company an edge on its competitors. If that research became public, then competitors that have their head offices in other countries could take advantage of research funded by UK tax payers! The issues aren't as simple as you suggest. -
Hyperactive Hydrologist at 09:01 AM on 22 November 2010Climategate: Tampering with Temperatures?
I think the UK could learn a lot from the US in terms of data availability. All data that has been funded directly or indirectly by the tax payer should be readily available to everyone. The availability of rainfall and flow data is also pretty poor, although it is improving. I also get a bit annoyed with the time spent on disproving deniers when we should be working on mitigation and adaptation. -
Daniel Bailey at 08:20 AM on 22 November 2010The human fingerprint in the daily cycle
Re: Camburn (24) If I understand you correctly, then yes, temperature by itself is a poor metric indeed (in the sense that it's extremely difficult to establish contextually what is really going on in the climate due to the noise in the signal). Would there only exist other, more accurate, ways of tracking climate change... Fortunately for us, climate scientists today use many metrics, such as temperature anomalies derived from terrestrial, marine & orbital data collection platforms, various proxy records, and many other measurable signatures of a warming world.

#20: "The ghosts are ... astonished that we are using temperature, by itself, as a measurement of heat of the atmosphere." There's very little that can be said in reply, except perhaps: temperature is a measure of the thermal energy held by matter. An immediate way of sensing this is by touching the material and deciding whether it is hot, warm, or cold. A thermometer precisely measures the temperature and records a numerical value for the temperature. Astonishing that we rely on numerical values as well. Perhaps the ghosts will also be astonished by that. -

KL #various Now that you've made the tacit admission that your main basis for intepreting the emails stolen from CRU is not acutally supported by the evidence, it's quite clear that you are aware that the premises for the starting point of your argument are fatally flawed. However, as you have not explicitly made this admission, and continue to pretend that everything is well with your argument, it seems that you are wasting your time trying to shore up an argument that you are aware is not supported by the evidence. -

fydijkstra at 06:58 AM on 22 November 2010The Fake Scandal of Climategate
And here is a rewritten version of the post to which Caerbannog (#26) replied: According to Longman’s Dictionary of Contemporary English a ‘conspiracy’ is ‘a secret plan made by two or more people to do something that is harmful of illegal’. It is a matter of taste whether certain events that are elucidated in the Climategate e-mails can be called a conspiracy. On 8 July 2004 Phil Jones e-mailed to Michael Mann about some papers by Michaels and McKitrick and by De Laat and Maurellis, both discussing the influence of urbanisation on temperature. About half of the observed warming could be explained from the warming effect of urban agglomerations. Jones and Mann were not amused, and Jones wrote: ‘I can't see either of these papers being in the next IPCC report. Kevin and I will keep them out somehow - even if we have to redefine what the peer-review literature is! Cheers, Phil’ Keeping some papers out of an IPCC report is not illegal. But is it harmful? The 2007 IPCC-report would certainly have been less comprehensive without reference to these papers. Affecting the quality of an IPCC report can be considered a harmful action. So, this ‘secret plan made by two or more people’ can be considered a conspiracy. Redefining what peer-review literature is, is not illegal either, although it is against the rules of scientific publication. And, moreover, it was impossible for Jones, Mann and Trenberth to redefine peer-review literature. This phrase can be considered boasting. It is no conspiracy. Nevertheless, this example shows, that there was at least one event that can be considered a conspiracy. This conspiracy was unseccesful. The papers by MM and DLM were mentioned in the final version of AR4. But Jones was successful in omitting the papers from the first and second draft. It was only after repeated comments by Steve McIntyre, that Jones was forced to add a paragraph. Conspiracy or not? Fact is, that the members of the Climategate e-mail club sometimes call themselves ‘the gang’ (11 times in the e-mails). Maybe that is another sort of boasting. My Longman’s dictionary says about a gang: (1) a group of young people who spend time together and often cause trouble and fight against other groups (2) a group of criminals who work together (3) humorous: a group of friends, especially young people (4) a group of workers or prisoners, doing physical work together. Which of the 4 definitions is appropriate is up to the readers. It’s their word, not mine! -
Composer99 at 06:47 AM on 22 November 2010The Fake Scandal of Climategate
As an extension of tobyjoyce's comment #43, I follow a few medical blogs (such as Science-Based Medicine or ScienceBlogs' Respectful Insolence), and I would venture to say that the two strains of science contrarianisms most often analyzed on those sites (anti-vaccination sentiment and anti-mainstream medicine) rely, on occasion, on strikingly similar arguments as some of the AGW contrarian claims that are documented here at Skeptical Science or that one might find when surfing over to WattsUpWithThat. Also, fydijstra in #45, I must beg to differ. The Lancet published a positively scandalous paper in 1998, retracted early this year, by a now much-discredited Briton who engaged in what amounts to scientific fraud. If the Wakefield 1998 paper, had it not been retracted, were to be included in an IPCC-style summary on the present body of evidence surrounding mass vaccination, it would be an unequivocal travesty. -
It's the ocean
h-j-m - The IR power emitted by the ground is a very straightforward application of Bolzmann's law, as well as per observation (with FTIR spectrometers and other instruments). And 396 W/m^2 is the correct number; that is what will be emitted from the ground and water at the current surface temperature. If you disagree with that, you're going to have to overturn a lot of physics! You don't feel it because at your body temperature you're emitting more than that. In an earlier version of the paper Trenberth estimated 390, then corrected it based on surface temperature variations - +/- swings around average temperatures, due to the T^4 term in thermal radiation, means that a varying temperature surface will emit a bit more than an evenly warm surface. The IR backradiation has also been directly measured, repeatedly and quantitatively, since the 1950's. (Stern, S.C., and F. Schwartzmann (1954) An Infrared Detector for Measurement of the Back Radiation from the Sky in J. Atmos. Sci., 11, 121-129. This documents early measurements of backradiation with a pyrgeometer). As to water vapor, you should read the page on Water vapor is the most powerful greenhouse gas. That states the scientific case regarding water vapor feedback more clearly than I can in a few lines. -

Folks, this post, among other things, should show you how utterly *incompetent* Anthony Watts and his "surfacestations.org" crew are. The "surfacestations" project has been active for *over three years*. And in the three+ years of project's existence, nobody affiliated with it has been able to produce even *one* cursory analysis of temperature data collected by the stations. This, in spite of the fact that the temperature datasets are no more than a few mouse-clicks away for anyone smart enough to figure out how to use a web-browser. It would have been a simple matter for the surfacestations folks to download and crunch the temperature data from the stations as they were conducting the survey. And it would have been almost a "no brainer" for them to compare temperature data collected from "well-sited" vs. "poorly-sited" stations in order to confirm or disprove their claims about temperature data quality. But in 3+ years' time, nobody affiliated with the project has done that -- this in spite of the fact that the gridding/averaging procedure is a task that capable undergraduate compsci/engineering students would have no problem implementing. It was left to others to perform the analysis work that the lazy and/or incompetent surfacestations folks were unwilling or unable to perform. The fact that the Muir Russell commission was able to do in *two days* what the Anthony Watts' and his surfacestations crew were unable to do in 3+ years should be a reminder to one and all how lazy and/or incompetent the folks who have been attacking the surface temperature record are. The surfacestations project is a complete joke; all the people associated with that project should be presumed incompetent until they can demonstrate otherwise. -

KL, May I point out the irony, neigh hypocrisy, of you (falsely) accusing others of "smear". I am merely stating the widely-known facts about NP and Corcoran. NP is being taken to court for very good reasons-- NP repeatedly libeled Weaver (and other scientists) and frequently fabricates or distorts information pertaining to climate science. By knowingly doing so, Corocoran is actually smearing his own reputation. In short, the NP is not a credible, trustworthy, or impartial source of information on climate science. Anyhow, Marco has addressed the misinformation that you quoted from NP in his post @57. KL, is the theory of AGW/ACC a hoax? The reason I ask is that I'm trying to figure out what your position is, because you seem both skeptical of the nuts and bolts (i.e., the science and data) as well as the scientists. In fact, you seem to opportunistically attack the science and scientists whenever you think that doing so will reinforce/support your belief system. My assessment of your posts here at SS is that you are a contrarian and that you think/believe AGW is either a hoax or a non-issue. I could be wrong, so please do state clearly for the record exactly where you are coming from. You might not believe this, but I often naively wish that I could wish away AGW, to make it a non-issue-- but the fact is, is that AGW/ACC is a reality and multiple, independent lines of evidence support a warming of around 3 C for doubling CO2 (and we will easily more than double CO2). And warming is not the only issue, the negative impacts of ocean acidification are already making their presence felt. -

For "skeptics", the temperature record is reliable just as long as it supports "cooling" or "no warming". If Phil Jones says the last 15 years had no warming trend to the 95% confidence level, then the record is spot on. If someone says it stopped in 1998, then NASA, NCDC and CRU are beyond suspicion. But if you point out the obvious long term warming trend, then it's just a bunch of numbers made up by the secret brotherhood of the warmist scientists. -

Ed @4, Thanks for picking up on that. I checked Michael's testimony again and he does not specify which records he is using-- he refers to using the CRU surface temperature data or using data from the Hadley Centre. So it looks like he may have been using both HadCRUT and CRUTEM, the fact that he did not uses the accepted nomenclature does not help. Anyhow, the whole point is the irony of the "skeptics" making (fallacious) claims as to the integrity of the CRU and CRU data, but then going on ahead and using those data repeatedly because they are underestimating the amount of warming.
