  1. CO2 lags temperature
    Archie, you're just basically resorting to adhominems now, so I'm going to leave you to it. I'm only interested in evidence. You can hardly speak of me having an agenda, and then make ad hominem comments. That's a sign of someone who can't debate, and doesn't really understand what he's talking about, but still want's the last word. A clear sign of someone with an agenda.
    Moderator Response: Please refrain from making 'ad hominem' accusations when none are actually made. Feel free to disagree, certainly, but be respectful when doing so.
  2. Waste heat vs greenhouse warming
    #320: "My use of the term refers to any and all heat that is imparted on any and all things on this Earth, assuming the first law of thermodynamics holds for fossil fuel consumption, which it does" Let's not be too hard on good ol' RSVP. In one post, he has tacitly endorsed: - warming is real (and thus - temperature record is reliable) - human effects are significant and causing the change (consuming fossil fuels liberates detectable heat) And simultaneously rejected the corresponding skeptic arguments (mainly 'its cooling'), but also some of the peripheral ones (if its anthropogenic, it's not 'the sun' nor 'cosmic rays' nor 'AMO/PDO/ENSO'). Probably a few more. All in all, I'd say RSVP is coming around. Of course,RSVP's basic premise may be tested by a simple experiment: if the energy consumed each year is directly reflected in atmospheric warming, we should be able to known match dips in historic energy consumption during recessions one-to-one with cooling episodes. For example, we've been in recession and thus it must have been cooler during this summer.
  3. There is no consensus
    @mistermack: "A page called "here is the best evidence for AGW" (or maybe I've missed it)." I already pointed towards it. Now, if you could indicate which information on that page is inaccurate (with evidence, which you keep asking for but never provide to support your own claims), that would be appreciated.
    Moderator Response: Also, mistermack, when on any page you see blue text, you should click on it, because it is a hyperlink to more information. And look past the end of each original post, because often there are green boxes with links to further reading and to related Skeptical Science posts.
  4. There is no consensus
    I'm replying to the link you offered me. It hardly follows that I think all the evidence is here. I politely read the link you offered, and responded. But to be honest, given the purpose of this website, I would have expected all of the best evidence to be summarised here. (somewhere) Perhaps that's a suggestion. A page called "here is the best evidence for AGW" (or maybe I've missed it). I would take it as read that we've had warming. (only the warming since 1950 should count, since CO2 rises were completely insignificant before that). So a page with nothing but evidence linking manmade CO2 to the warming since 1950 would be absolutely brilliant.
    Moderator Response: The Big Picture
  5. CO2 lags temperature
    @mistermack: "This timescale argument is a bit silly." What is silly is your insistence to ignore all the information we provide you in order to continue pushing your agenda. There is a wealth of information for you here, but you are not interested in learning the truth, it seems. "When you talk about the CO2 supply in the ocean dwindling, and turning off a feedback loop, ten thousand year would be incredibly sudden." Tom explained it quite well. It doesn't mean that there is no more CO2 in the ocean, but that the conditions for the CO2 outgassing are no longer present. Again, the fact you don't understand the science doesn't make it invalid. Stop being so arrogantly certain that you hold the truth and start learning some actual science.
  6. Waste heat vs greenhouse warming
    RSVP - I have to admit, reading this post of yours made me laugh. Raising the temperature 0.015°C to 0.034°C is sufficient to radiate 15 TW/year to space (i.e., all of the anthropogenic heat flux), balancing the energies involved. At that point the Earth stops warming from AHF. And that warming is lost in the noise of the GHG driven temperature rise. Again, and (I'll try, really), my last post on this. Waste heat/AHF is 1% the energies of greenhouse gas entrapment (0.028 W/m^2 versus 2.9 W/m^2), and is therefore not the dominant cause of global warming. This skeptic argument is busted.
  7. Blaming global warming on the oceans - a basic rebuttal
    TTTM #16 Recall my previous comment at #12 "The "none of the above" answer could be true on some level of analysis, but is not a terribly useful proposition for the present discussion." However, if you have some useful evidence that suggests that your new premise is correct please share with us. Otherwise it looks like you've moved on from a circular argument to some other sort of fallacy.
  8. There is no consensus
    I did read more. I noted that it's claimed "we know that....." without saying how. I don't want to get off topic, but a model doesn't justify "we know that", you could maybe say "we calculate that...." or "our best estimate is....." What this seems to indicate, is that the "consensus" is basically the result of faith in models. Yet others are telling me that they think it's the result of evidence. I still think consensus has built itself up in a feedback loop.
    Moderator Response: Why on Earth do you think all the evidence is in this blog? The authors of these blog posts go to considerable trouble to cite, and when possible link to, the peer reviewed scientific literature so that blog readers can go there if they want more info. Commenters responding to you have done the same. It's past time for you to take advantage of those resources.
  9. CO2 lags temperature
    Tom, re your previous comments, the ten thousand years was my estimate, snatched out of the air, but bearing in mind that there is an 800 year lag between a temperature rise showing even the slightest rise in CO2 levels. How long would it take to significantly reduce CO2 availability in the ocean significantly? Especially as oceans should be significantly warming all the time.
  10. Blaming global warming on the oceans - a basic rebuttal
    I am always baffled by the inability of denialists to apply the 700 year old commonsense of William of Ockham. "Oceans releasing heat" is just one of many "mechanisms" that rely on no one noting the strange fact that they are supposed to have come into play just in the last 40 years at precisely the time that there has been industrialisation, population growth, and a resulting rapid rise in CO2 levels in the atmosphere. Some coincidence eh?
  11. CO2 lags temperature
    Tom, I would agree that a "burp" mechanism would be interesting. But it would need to be demonstrated that it could be significant on a global scale, not local. And in that case, you would expect to see a clear signal in the ice cores. I wouldn't discount it as being possibly significant, but it would need more evidence of a worldwide effect. I can't visualise a "gulp", working at the top of the cycle though.
  12. DMI and GISS Arctic Temperatures: Hide the Increase?
    Hi Peter and klaus :-) I did not expect acurracy, but im not sure why the latest years should have mor descrepancy than the other years. Here my 2010 point: http://hidethedecline.eu/media/BLANDET/dmi2010.jpg -a value less than +0,4 deg C appears correct still, so im not sure what to make of this. But :-) There is a decline in temperatures of perhaps 0,5 K 1991 - 2010 -and this is something quite else than the GISS trend GISS 80N-90N summer data: http://hidethedecline.eu/media/GlobalIceExtend/fig2.jpg GISS shows no sign of cooling trend, only warming for summer 1991-2009 80N-90N. And of course yearly anomalies are very interesting´indeed, but yearly anomalies does not make errors in summer anomalies go away. K.R. Frank
  13. There is no consensus
    Responseman, I looked at "Climate sensitivity is low", the first sentence is :"There are some things about our climate we are pretty certain about. Unfortunately, climate sensitivity isn’t one of them". That makes my point for me. The "consensus" is there, in spite of the lack of certainty about the central tenet of AGW. That is, is the climate sufficiently sensitive to CO2 for there to be a problem? I argued that the consensus is fortified by the consensus in a feedback loop, not by certainty of the evidence.
    Moderator Response: Read past the first sentence. Click on the "Advanced" tab. Read the section "What is the possible range of climate sensitivity?" Note that certainty is high regarding the lower limit of sensitivity, and that even that lower limit will have serious adverse consequences. (You need to read the entire Advanced post to get all that.)
  14. CO2 lags temperature
    mistermack, why are you claiming that the cause of reduced CO2 levels was dwindling of the CO2 content of the ocean? The ocean's role in adding or removing CO2 from the atmosphere depends on the temperature, CO2 concentration, and other chemistry in the ocean, but also on temperature and CO2 concentration in the atmosphere. Unlike in the atmosphere, CO2 in the ocean is not so well mixed, which is why its role in triggering reversal of ice ages seems to hinge on ocean currents bringing CO2-rich water up from the depths. Changes in any of those factors can change the rate at which CO2 outgases from the ocean, and even reverse the direction to absorption. Changes in any of those factors can come from any number of other factors, including change in seasonal insolation due to orbital progression. An example is that suggestion of a CO2 burp from the southern ocean being a trigger of at least one particular ice age. Burps have starts and ends. The notion is that deep CO2-rich water upwelled "suddenly." But that would have depleted that deep reservoir of CO2-rich water. So that extraordinarily high rate of CO2 outgassing would have been a "short" duration event.

    The 2nd law of thermodynamics and the greenhouse effect
    Em tempo: A lei de Stefan-Boltzmann tem apenas dois parâmetros; area e temperatura. At time: The Stefan-Boltzmann law has only two parameters, area and temperature.

    The 2nd law of thermodynamics and the greenhouse effect
    TonyWildish Pense em "ganho de antena". Só é possivel porque as ondas eletromagnéticas não seguem a 2nd lei da termodinamica. Elas seguem a lei da sobreposição linear das ondas mecanicas. Na atmosfera; Um mol de N2 colocando-se uma molécula ao lado de outra, cobriremos 92,7 m2/mol ou 6,62 m2/gr e cada m2 representa um elemento radiante. Como o ganho de antena é igual ao numero de elementos radiantes teremos 6,62 vezes a radiação de um m2 para cada grama de N2. Think of "antenna gain" . I's possible only because the Electromagnetics waves do not follow the 2nd law of thermodynamics. They follow the law of linear superposition of mechanics waves. In the atmosphere; One mole of N2 placing one next to another molecule, will cover 92.7 m2/mol or 6.62 m2/gr and each m2 represents a radiating element. Because the antenna gain is equal to number of radiating elements will have 6.62 times the radiation from an m2 per gram of N2.
  17. There is no consensus
    mistermack at 06:53 AM on 25 October 2010 Please read Lean 2010, and look at figure 6.
  18. CO2 lags temperature
    mistermack, what is the basis for your claim that ten thousand years would be an incredibly sudden period for CO2 feedback to dwindle?
  19. CO2 lags temperature
    This timescale argument is a bit silly. This IS the climate timescale. When I write sudden, I mean sudden in climate terms. Surely that's obvious? What's sudden to the climate of the earth is not sudden to a kitten. When you talk about the CO2 supply in the ocean dwindling, and turning off a feedback loop, ten thousand year would be incredibly sudden.
  20. There is no consensus
    @mistermack: Climate Sensitivity is estimated at between 2.5C and 4C. If you have evidence to the contrary, by all means present it. So far you have failed to do so. As for the NASA page, it clearly shows the current level of CO2, and we know CO2 "greenhouse gas" properties will increase temperatures. We also know this extra CO2 is from anthropogenic sources. Therefore, it is very likely humans are responsible for the current warming. Again, you have failed to produce a single piece of evidence that disputes this. The burden of proof is on you - better start working on that thesis! At least you agree it's warming, even if you're ready to gamble civilization's future just because you disagree (without evidence) about climate sensitivity.

    DMI and GISS Arctic Temperatures: Hide the Increase?
    Peter Hogarth at 06:30 AM on 25 October, 2010 Thank you Peter Hogarth This is what I whant to see. Looking forward to read the excel sheet with DMI data. Regards Klaus Flemløse
  22. There is no consensus
    Archie, your page from the "know nothings at NASA" showed evidence of warming. We all know we've had warming. What's not there is good evidence for the title "anthropogenic". That's what's always missing.
  23. There is no consensus
    Archie, your link, "evidence is there" just illustrates my point perfectly. The relevant question is the sensitivity of the climate to CO2. Will increased CO2 cause a big enough rise in temperature to cause problems. That's the one bit of evidence missing. The relevant bit. The rest is just window dressing. I didn't say there is no evidence about anything. I'm saying that you need evidence for the central tenet. Link me that, if you like.
    Moderator Response: Climate sensitivity is low and It’s not bad
  24. CO2 lags temperature
    mistermack, you continue to refuse to acknowledge the importance of the time scales of the graphs. Try mentally zooming in on Figure 1 at the top of this post until its x axis had the same time scale as the graph of temperature response to cessation of human emissions. The "sudden" drops would not seem so sudden. Or zoom out of the the graph of temperature response to cessation of human emissions until its timescale matches that of Figure 1. Then the "gradual" drop would seem just as sudden as Figure 1's drops. What seems to you personally to be unrealistic and unreasonable rates of decrease when you look at a graph zoomed out so far, in fact are completely reasonable when the actual times involved are recognized.
  25. CO2 lags temperature
    @mistermack: again, you are misled by the time scale used in the graphs. The changes seem sudden to you because the scale is in hundreds of thousands of years. If you were to see these changes happen on a much smaller scale, they wouldn't look so sudden, and would be consistent with the feedback loops ending. Also, Tom has not claimed that a drop in CO2 is what drove the climate down. Instead, CO2 is a *feedback* mechanism in those cases. You won't learn much (and you clearly have much to learn still) by refusing to listen to rebuttals to your erroneous claims.
  26. There is no consensus
    @mistermack: Here some more evidence of anthropogenic global warming, from those know-nothings at NASA...
  27. DMI and GISS Arctic Temperatures: Hide the Increase?
    Klaus Flemløse at 05:18 AM on 25 October 2010 Thanks. I will post the Excel values in a few days if I have somewhere to post them here! I will be out of e-mail range over next week. Anyway, whilst seeing if there was a nice publicly available version of DMI I have found a website called Climate Sanity which has also created yet another “pixel counting” numerical version of DMI (through some of 2009), along with a relevant article (I will not pass judgement on the overall site!). I have also checked this data and was interested to see how good a match it is to DMI. The overall averages and trends seem very well matched. My own attempt at "pixel counting" gave errors quite similar to Franks (but in different places). I have calculated the above zero degrees average for all three data sets using Franks table. The overall trend of the difference between the Lansner and DMI values is -0.02 degrees C/decade. Whilst this is not really significant, we can see below that most of the significant errors seem to be in recent years.
  28. CO2 lags temperature
    Tom, if the graphs remotely resembled a process "petering out", I would have to agree. However, as I've pointed out so many times, they don't. Draw your own graph, of a feedback loop "petering out". What does it look like? Does it resemble the ice core records? And why don't the CO2 graphs jump in front of the temperature graphs when that happens? If a drop in CO2 is pulling down temperatures?
  29. There is no consensus
    @mistermack: "Archie, if the evidence was as overwhelming as you say, I wouldn't waste my time looking." The fact you are "still looking" doesn't affect the quality of the evidence in now way. I'll surmise that the reason you are still looking is that you have failed to understand the science, probably because you're too biased towards your preconceived notions to be receptive to it. Again, the evidence is there, and you have yet to present a convincing claim against it. "I know for a fact that the evidence is debateable, because I've done a lot of looking, much more that the average student intake." That's argument by assertion: "I'm right because I say I am." Sorry, but that logical fallacy won't cut it here. "I think I am therefore well justified in my conclusion that most people are initially convinced by the "consensus" rather than evidence." No, you're not. You haven't presented a shred of evidence to support your accusation. Therefore, the only think we can conclude is that you don't seem to know what you're talking about. "You mention doctors, but many doctors are also homeopaths, and many are "experts" in homeopathy." That's an attempt at changing the subject, and in fact *very few* medical doctors are homeopaths. Medical experts, and the current state of medical science, condemns homeopathy as the hoax it is. "The concencus of experts in homeopathy would be overwhelmingly supporting the effectiveness of homeopathic remedies." Homeopathy is not empirical science, and the vast majority of medical experts do not accept homeopahty and its alleged remedies are effective. So your example fails. "Same applies to Chirpractic." Again, that is not a valid examples, because chiropractors are not necessarily experts in medical science (and in fact I suppose very few do). These examples fail to support your anti-intellectual attack on experts. "I'm not saying that climate science is as silly as these," No, but you're certainly implying they are similar. "I'm just pointing out that a consensus is naturally self perpetuating, till it's disproved." Again, there is no indication that people who study climate believe in AGW because of the consensus. Rather, the consensus exists because the evidence (which you *choose* to ignore) indicates AGW is very likely true. "That's why the consensus on AGW is totally valueless, as evidence." Well, that's right in an of itself. Note that the article isn't claiming that the consensus is evidence AGW is true - it doesn't. Rather, it is a rebuttal of the contrarian argument that "there is no consensus," when in fact there is (as you yourself have admitted a few times in this thread already). So, again, the contrarian argument is that there is no consensus (hence such farces as the Oregon petition project), the rebuttal is that there is. You arguing that the consensus is meaningless is off-topic (and wrong in your characterization of the consensus). Please stop insinuating that people who study the climate are motivated by groupthink rather than rational thought. It's insulting, and goes against site policy (as it suggests a conspiration of dunces). "In climate science, you can't even predict next year's trend. But you can grandly predict the trend for the next century." Indeed. "Without the slightest risk of being proved wrong." So far, they haven't as temperatures are quite close to predictions - but I'm sure you'll change the subject and start attacking the quality of temperature records next. Contrarians are *so* predictable...
  30. CO2 lags temperature
    mistermack, you are incorrect that runaway warming was happening but something else stopped it. Positive feedbacks that are not of the runaway variety never can run away. They are self-limiting. Each little bout of positive feedback is just that--a little, short-lived bout that inherently, by its fundamental nature, will die out. They do not strain toward running away. They are introspective. Belly button "innies" rather than "outies." In our current era, there is a lot for us to worry about despite the lack of the runaway variety of positive feedback, because we keep adding greenhouse gases; our addition of greenhouse gases is a forcing. The non-runaway positive feedback amplifies the effects of those additions. If we suddenly stopped adding greenhouse gases and all other emissions, temperature would continue to rise for several years due to the Earth working toward equilibrium, but then the temperatures would fall. If we continued to emit but at a constant rate instead of an increasing rate, temperature would continue to rise for longer but then would asymptote. Tying all that back into the topic of this post: Those past CO2 positive feedbacks also were not of the runaway variety. So they, too, inherently would peter out. Unlike the human-caused addition of CO2, there was no forcing by independent addition of CO2. CO2 was instead acting as a non-runaway feedback. Other, forcing and feedback, factors needed to keep stimulating the system and thereby prompting more (non-runaway) positive feedback from CO2. Most prominent among those factors was orbital cycles, but there also were effects of changes in vegetation, dust, snow and ice cover,.... So your question "what made the temperature rise stop" is ill posed. The better question is "what made the temperature continue to rise as long as it did?"
  31. There is no consensus
    Doug, that's an incredibly weak argument. Who's going to draw attention to their incorrect predictions? They get conveniently forgotten, and we are left with amazingly accurate forecasts. It's like a bankrupt gambling addict telling you about his big wins.
  32. Blaming global warming on the oceans - a basic rebuttal
    Gray says global warming is "likely a result of the natural alterations in global ocean currents". Perhaps another argument against this is to examine the wavelengths of known ocean oscillations, like El Nino. These seem to occur in time periods less than 10 years, even less than 3 years, despite being global in extent. This argues that a natural alteration with a multi-decadal wavelength is unlikely. And if it involves salinity, how did that happen, if not through global melting, due to global warming? It seems the simplest explanation is still the best one.
  33. There is no consensus
    Phil, you can talk up climate science all you like, it involves physics and chemistry, but that's where the similarity ends. You can make predictions in physics and chemistry, and verify them. In climate science, you can't even predict next year's trend. But you can grandly predict the trend for the next century. Without the slightest risk of being proved wrong.
    Moderator Response: You are solidly in the topic of a different thread now: "Models are Unreliable." Use the Search field at the top left of this page.

You can find it below: http://hidethedecline.eu/media/BLANDET/DMIIS.xls I understand from your latest remarks that you have access to the corresponding data from DMI.

  37. Waste heat vs greenhouse warming
    Speaking of IR antennas or at least something in the same domain of recovering wasted heat energy, thermionic junctions are finally showing some promise for recycling of waste heat on a large scale. More nanotech goodness...
  38. Waste heat vs greenhouse warming
    @RSVP: AWH represents about 1% of AGHW. Therefore, about 1% of the temperature incraease is due to waste heat. Why are you still arguing about this (apart from wasting peopel's time, which I suspect is your true objective here)?
  39. There is no consensus
    Actually the first relatively back-of-the-envelope style calculations of the net effects of CO2 forcing were remarkably close to what we're seeing, mistermack. The earlier model predictions also produced results that can be considered reasonably useful in light of how things have since progressed. Early calculations were done some 50 years ago or more, model runs were first being done over 30 years in the past, so this is hardly "brand new." One can of course say, "oh, they were just lucky" but that's really not sufficient.
  40. There is no consensus
    Mistermack @246 most science can be verified by experiment No, science is verified by observation. Experimentation is, of course, just a "fast track" way of making observations. For some sciences, (Astronomy, Ethology, Geology) experimentation is difficult, if not impossible; for others (Economics, Human Development) experimentation can be considered immoral. Climate science is actually largely, if not entirely, the application of physics and a little bit of chemistry to a specific system - the Earth and its atmosphere. Experiments pertaining to climate science, and indeed think about the effects of CO2 on the energy balance have been going on for about 150 years.
  41. There is no consensus
    @mistermack: "How many new students in the climate science field come into the subject without an opinion on global warming? And what it the overwhelming opinion going to be? Pro, of course." This is irrelevant. Most people believe in AGW because the evidence is there, and the science is convincing. One has to be pretty arrogant to assume that the majority of people going into climate science are led by irrational belief rather than actual scientific knowledge. "If you didn't believe in global warming, you would be crazy to choose climate science as a career." It's not a matter of belief, but of logical reasoning. We accept AGW as very likely true because the evidence clearly suggests it is. "So every new intake is already convinced of AGW, generally because of the concensus." The consensus exists because the science is pretty compelling. The fact the science is so compelling is the reason many contrarians choose not to debate the science, but rather attack the integrity of those who understand it by claiming (without evidence) they are victim of groupthink. This is what you're trying to do now. It's insulting, not to mention factually wrong. "In fact, in any field, most "experts" are understandaby apologists for the concensus." And that means they are wrong? Is a doctor an apologist for treatment because he's an expert in it? Is a general an apologist for good military strategy because he's an expert? Your position seems to be that the more someone knows about something, the less we should trust that person. That's nothing more than ole' fashioned anti-intellectualism. the bane of scientific thought. You assume the experts are wrong simply because you don't agree with the conclusion...that's not a logical position. "There is an incredibly similar situation in the field of Bible study. The huge majority of people entering the profession are already believers." Actually, the situation is very different, because Bible study isn't empirical science. It's simply the study of Christian religious texts. Again, you try to attack the reputation of those you disagree with, this time by likening them to religious people. The sad thing is that, by espousing false ideas not based on logic and trying to discredit honest scientists, *you* are the one acting like the anti-sciece fanatical religious fringe.
  42. There is no consensus
    Hi Phil, from the little I know, QM and GR contradict each other in places, and both fail when applied to the very beginning of the big bang. However, my real argument would be that most science can be verified by experiment, and maths by proof. Climate science is brand new, with no track record, and has a record of NO correct predictions so far. ( I mean real predictions, not retro ).
    Moderator Response: You are wrong. In the Search field type "Models are Unreliable."
  43. There is no consensus
    Mistermack @242 says: A concensus IS a feedback loop. Especially if it exists in a scientific community. There is scientific consensus on General Relativity and Quantum Mechanics and Darwinian Evolution ... Does that mean they're wrong ? Why should it for climate science ? There is an incredibly similar situation in the field of Bible study. I had a friend that lost her faith studying Theology. Her view was that the lecturers threw every argument against religion at the students to ensure students could overcome any "doubts". For her the doubts got the better of her. She was quite bitter about it :-(
  44. Blaming global warming on the oceans - a basic rebuttal
    #20 How about we assume that GW is caused partly by ocean surface temperature, partly by CO2 level and partly by sunspots? How about we back up our assumptions with the best available science, instead of relying on dodgy pseudoscientific sites?
  45. There is no consensus
    Truevoice, firstly, are you saying then that the scientific consensus is never wrong? I'm afraid I have to disagree. And you don't attempt to refute my points, you are simply argueing by assertion yourself. I think you should reread your own link, and look up "irony".
  46. Waste heat vs greenhouse warming
    RSVP, All heat imparted from our technology is by definition "waste". All of it. The heat which comes from friction, A/C, factories and electronics is all due to inefficiency. Your assumption that waste heat is enough to warm the planet by 0.1C per year is based on a faulty premise. Nor have you demonstrated the effect of "waste heat" is more than the +0.028 W m−2 identified by Flannery. If you have identified a flaw in his paper, please point it out to us.
  47. CO2 lags temperature
    MrResponse, I have read that article about runaway warming, someone already linked it on this thread. But you can't have it both ways. If there is a built-in mechanism that stopped runaway warming, (as seems perfectly clear anyway from the graphs), then there should be little to worry about. And also, what is the mechanism that happens so suddenly (suddenly in climate terms Archie), and sends the whole process into reverse? There is nothing similar to that in the page you linked. If it was the CO2 supply dwindling in the ocean, wouldn't it happen incredibly slowly? How do you think that could happen quickly, and go straight into steep reverse, as I asked? People seem to be dodging the difficult question here.
  48. There is no consensus
    Mistermack, The difference in religious studies and science is that science is self-correcting, using the most rigorous methodology of discovery humans have ever invented. Providing links to arguments about religious experts tells us absolutely nothing about science or the field of climatology. Your statements regarding a "consensus" are yet another Argument by Assertion, a logical fallacy. I strongly suggest you spend some time at the Fallacy Files before posting here again. You'll be able to make a stronger case for your point of view.
  49. Blaming global warming on the oceans - a basic rebuttal
    @Dan: Dude, 'climaterealists.com'? This is a denier website. You were misled by the innocuous URL.
  50. Explaining Arctic sea ice loss
    D Kelly O'Day at 09:40 AM on 19 October, 2010 Sorry about the delay in responding. I fitted a linear trend to the HadCRUT series, then worked out the exact monthly increment for that trend, then generated a monthly cumulative time series and subtracted these values from the corresponding original monthly data values, (then back-checked the result!). This is crude but effective. Hope that makes sense.
