    Every time I see this quote, I find myself wondering...

    Does Christy understand what "consensus" means?
    Does the person supplying the quote understand what "consensus" means?
    If both of them do understand, then what are/were they each trying to achieve with this quote?

    Yes, there is a consensus. Pretty-much by definition, that means that there isn't unanimity, and therefore it is a given that some scientists disagree.

    To be honest, it doesn't really matter what any one scientist says or believes. It matters what the science shows.

    Christy can believe in whatever he likes. Belief is not science....and Christy (presumably) is smart enough to know that.

    No no, Prof Christie doesn't get to make up his own definition of scientific consensus.

    University of Illinois carried out a survey on belief in climate change last year with the result that 97% of climatologists who are active publishers on climate change accept anthropogenic climate change. What you have done is found one and quoted him. It doesn't change the fact that 97% do.

    One swallow does not make a summer I'm afraid, no matter how much you want it to.

    I suppose it was to be expected that you might rush off and try to find something which flatters your own (apparently made up) mind, rather than consider whether someone who is extraordinarily qualified and involved at the forefront of the science has to say. It appears that, simply because you don't like what he says, then you decide to rubbish it, and him, and ignore him.

    So what you are saying is that you prefer to believe Bonkey, an anonymous profile on the interent, and whose input to the IPCC reports, if any, and qualifications, if any, are not known, and a survey, rather than even consider what Professor John Christie, M.S, Ph.D, B.A., Distinguished Professor of Atmospheric Science and Director of the Earth System Science Centre at the University of Alabama, was awarded NASA's Medal for Exceptional Scientific Achievement, a Special Award by the American Meteorological Society, has served as a Contributor (1992, 1994, 1996 and 2007) and Lead Author (2001) for the U.N. reports by the Intergovernmental Panel on Climate Change, on five National Research Council panels or committees and has performed research funded by NASA, NOAA, DOE, DOT and the State of Alabama and has published many articles including studies appearing in Science, Nature, Journal of Climate and The Journal of Geophysical Research, has to say.

    Fair enough.

    The point I was making was about the meaning of the word consensus.

    The existence of a consesnsus does not prevent one, or many scientists from disagreeing with the consensus. Conversely, the existence of one or many scientists who disagree with something does not preclude there being a consensus.

    Incidentally, I would note that only a few posts ago, you were calling the IPCCs credibility into question. Now you're holding up a lead author of their work as a poster-child for your position.

    And just because its annoying me...if you're going to quote the guy's qualifications repeatedly, could you at least take the time out to get his name right?

    Just because I deduce, from the evidence, that the IPCC's credibility is damaged by issuing statements which are later seen to be flimsy, or incorrect, doesn't mean they are always wrong.

    My "poster boy" ? I don't have a position, and just find many aspects of this debate interesting. That you think I have a position to "defend" is your assumption, and is incorrect. Just because someone doesn't necessarily agree with you doesn't mean they are defending a position. What has surprised me here is that, rather than being interested in what an eminent man in the field has to say, your instinct appears to be to want to rubbish him because you don't like what he has to say.

    The desire to rush to defend what you appear to see as your position, and avoid challenging what appears to be your position is, perhaps, not the most intelligent position to take.

    So on what basis might one deduce whether or not the IPCC, or an individual who has worked with the IPCC, is correct? Judging the evidence upon which their claims are based, perhaps?

    We've seen this also with the IPCC, a body which has seemed more interested in pushing its own agenda and is prepared to be rather more than economical with the truth.

    All of this damages the case they make in anyone with a smidgeon of intelligence, as it becomes harder and harder to believe those whose agenda is other than the pursuit of truth.

    No, bonkey did not “rubbish” what Christy said, he merely queried both the quote itself and your reasons for producing it. Queries that you have conveniently overlooked I might add, together with numerous other rebuttals and questions on this thread.

    Then you would surely agree that the correct approach would be to test any given statement from the IPCC and/or its members, to see whether or not it is correct, and to accept the best conclusion we have?

    This, of course, is what is done with the IPCC's reports. The reason the flaws were found is because responsible scientists took the time to continue reviewing the material. They found some small errors, which have since been corrected. Its worth pointing out that these people were amongst those who collated the reports in the first place....they are amongst those who's credibility you suggest is damaged by all of this!

    You have taken issue with the notion that things are presented as "fact", but the reality is that they're not....at least, not by the IPCC. If you get the information second- or third-hand, someone else may be claiming its fact, but not the IPCC.
    your instinct appears to be to want to rubbish him because you don't like what he has to say.

    I'd never think of rubbishing the man. I have a lot of respect for him, as it happens. In fact, its one of the reasons I felt it important you got his name right.

    The comment, however....well...lets look at it a bit closer...

    Its not quite clear whether Christy is disagreeing with the notion of catastrophic impact, or the notion of consensus. If its the former, its entirely unclear what constitutes "catastrophe". He could, alternately, be saying that there isn't a consensus. He could be saying that there is a consensus, but even still there are "many" who aren't amongst that. He may be referring to relevantly-qualified scientists, or he may not.

    Its a brilliantly formulated, vague sentence, which is frequently presented as being something significant...just as you've done. Christy's own track-record is typically then leveraged, as though this somehow makes it more significant.

    At the end of the day, its saying that Christy is amongst some unquantified "many" who disagree with some not-so-well-defined claim that "others" have made.

    How can you test a prediction as to what the climate will be like 50 or 100 years hence?

    The really important thing the IPCC has to do is to predict the future. This is largely achieved by telling a computer how to react to information, then inputting the information, and treating the results as serious. It's amazing how many otherwise intelligent people will take something seriously if its told something by a computer.

    (1)For example, I can programme my computer that CO2 is the most important factor in driving climate change, and can instruct my computer to take CO2 changes and apply those to a graph into the future to show that increases in CO2 will result in increases in global warming.

    (2)If , instead, i programme my computer with the information that CO2 follows increases in temperature, then the predictions of the future will be completely different.

    Now here is a question:

    Which of the above, (1) or (2) , is the way most of the computers on which the IPCC's predictions are based?

    Now here is another question:

    Do the ice core results being studied around the world, for example in Vostok by Geerts and Linacre show, historically, that CO2 happens before, or after, temperature changes?

    Now, you know full well I know the answer to my own question, and I know the answer appears that, far from CO2 causing temperature changes, it appears temperature changes happen first, then the CO2 follows.

    Do you think, if the computer models which are programmed to assume that CO2 leads temperature changes, and not that it follows them, that the subsequent predictions may not be accurate?

    Neither - you're implying that the models are designed in such a way as to produce a result that agrees with a pre-established conclusion, which is nonsense.

    If you’re going to persist with your rubbishing of modelling, I suggest you read up on the subject first. As I have already stated (twice), mathematical equations have been successfully used by humans to describe the universe around them for centuries – you seem to be conveniently overlooking that fact.

    Friendly Mod Reminder: Repeating an argument ad nauseam while ignoring responses from other posters is called ‘soap-boxing’, a practice that is frowned upon on most boards fora, including this one.

    Your entire objection is based on a statement which you insist was shown to be wrong. Now you're arguing that you have no way of knowing if the statement was right or wrong.

    Strange...

    No more amazing then how many people seem to think that a lack of understanding of mathematical modelling is sufficient grounds to dismiss it.

    Both and neither, actually.

    The people doing the modelling understand that there is a feedback effect....that increases in CO2 through effects other then warming will lead to warming, which in turn leads to its own increases in CO2, which in turn leads to further warming.

    Additionally, they understand the general mechanism by which this doesn't result in a runaway effect, and model that too.

    Thus, the models show that increases in CO2 regardless of origin lead to warming, which leads to increases in CO2 amongst other factors. This creates a feedback loop, regardless of whether or not the original increases were caused by warming or some other source. This feedback loop is ultimately dampened by other factors.
    Do the ice core results being studied around the world, for example in Vostok by Geerts and Linacre show, historically, that CO2 happens before, or after, temperature changes?
    Historically, how many civilisations have dumped comparable amounts of CO2 into the atmosphere? None. So historically we'd expect to see no precedent for current events....so its hardly surprising that we don't.
    Now, you know full well I know the answer to my own question, and I know the answer appears that, far from CO2 causing temperature changes, it appears temperature changes happen first, then the CO2 follows.
    It appears that you don't know the answer to your own question as well as you think.
    Do you think, if the computer models which are programmed to assume that CO2 leads temperature changes, and not that it follows them, that the subsequent predictions may not be accurate?
    If someone was dumb enough to program CO2 as purely a forcing agent, then yes...I'd expect their model to underestimate the effects of increased CO2.

    If one, or more, of the assumptions is incorrect, then so too will be the accuracy of the predictions.

    No matter how good the mathematics are, if the assumptions are wrong then the conclusions wil be incorrect also.

    For the sake of accuracy, I am not "dismissing" the mathematical model, I am questioning one of the assumptions.

    Of course they show it because that's one of the assumptions on which the which theory is based, that CO2, as one go the greenhouse gases, causes global warming. Hence that assumption is programmed into every computer model.

    How many have "dumped" (interesting you choose a pejorative word usually associated with (often) toxic waste) water vapour into the atmosphere?

    How many have "dumped" methane?

    The point of the ice cores is that, historically, it seems CO2 does not cause warming, but is a product of warming. Even if we produce more CO2 now that we have in the past, thats not to say that the relationship between CO2 and warming is going to be reversed.

    How do you account for the findings of Geerts and Linacre, amongst others, who found that in times of cooling the CO2 changed after the temperature change, by up to 1000 years. This order of events is not what one would expect from the enhanced greenhouse effect.

    How do you think that fits with the theory, as opposed to the evidence of Geerts and Linacre?

    Yes...that's true, if somewhat simplistic.

    The more complex reality is to look at the level of accuracy which is obtainable.

    To perhaps give a parallel example. When we build buildings, we use Newtonian physics. If we used the same physics for launching spacecraft to Mars, we'd have a problem...because of what could be described as "incorrect assumptions". We know that Newtonian physics is only accurate to a point. Once we cross that point, we need to use Relativistic physics instead.

    So we in the simplistic black-and-white scenario you present, Newtonian physics is incorrect, and so therefore is the accuracy of its predictions.

    In the more complex real world, we know quite a lot about the degree of inaccuracy.

    In climatology, we know that the models are imperfect, as are the inputs. This is why predictions aren't weather forecasts (in the extreme case) for the future, bur are (more realistically) spreads of likely outcomes, expressed in terms of the confidence we can have in the accuracy of those intervals.

    So like I said...its amazing how a lack of understanding of modelling allows people to dismiss it.

    For the sake of accuracy, I am not "dismissing" the mathematical model, I am questioning one of the assumptions.
    Really? It seems to me like you're trying to point out that there are huge gaping simple and obvious flaws in the models...flaws which aren't actually there if you understand the models at any level beyond what the mass media might be reporting. At the same time, your arguments show a lack of understanding of modelling.

    If you're questioning the models, might I respecfully suggest that the first two things you should do is learn more about modelling in general, and the models that you're "questioning" in specific/
    Of course they show it because that's one of the assumptions on which the which theory is based, that CO2, as one go the greenhouse gases, causes global warming. Hence that assumption is programmed into every computer model.
    Its also an assumption that is supported by evidence, as well as by basic science.

    As I've already explained, being both a force and an effect means that the historical evidence you've referred to is entirely consistent with this model.
    How many have "dumped" (interesting you choose a pejorative word usually associated with (often) toxic waste) water vapour into the atmosphere?

    How many have "dumped" methane?
    Look...either you know why water vapour and methane aren't significant issues, or you're again showing further lack of understanding of the basic models that you're questioning.

    These are old canards which have been answered again and again.
    The point of the ice cores is that, historically, it seems CO2 does not cause warming, but is a product of warming.
    I've already responded to this point, and you're simply repeating the same claim and ignoring my response. I see no point in addressing it a second time.

    Again, no argument. Water vapour is the most important greenhouse gas and methane is 20 times more effective in trapping heat in the atmosphere than CO2.

    I'm not sure what argument of Geerts and Linacre you are referring to, but given you're track record on this thread, I'm guessing you're (deliberately) misinterpreting them. I'm pretty sure bonkey has already countered whatever argument you're trying to make here anyway.

    But let's try and establish some basics, shall we? Do you accept that carbon dioxide a greenhouse gas?

    I'm going to go out on a limb here and guess that Geerts and Linacre might have slightly more to say on the matter? What words preceded 'CO2' in the original statement, I wonder?

    With respect, my reply has been an explanation that the assumption you speak of is a gross simplification of what has been built into the model...and it is the simplification which causes your argument to fall apart.

    That CO2 causes warming is built into the model...because scientifically that is demonstrably true. The evidence supports this.
    That warming increases CO2 is also built into the model, because the evidence also supports this....as you yourself have argued.
    That’s not an argument, and to claim that the assumption that CO2 causes warming ignores the scientific evidence of, for example, the Ice core work done by Geerts and Linacre.

    Unfortunately, Geerts and Linacre disagree with your opinion, and expressly say that “…CO2 changed after the temperature change, by up to 1000 years. This order of events is not what one would expect from the enhanced greenhouse effect”.
    Lets look, firstly, at their full statement (taken from here)

    During deglaciation the two varied simultaneously, but during times of cooling the CO2 changed after the temperature change, by up to 1000 years. This order of events is not what one would expect from the enhanced greenhouse effect.

    So, Geerts and Linacre assert, in fact, that during periods of warming the CO2 levels increase in line with temperature. The partial quote you supply refers to effects during a cooling phase. Although they argue this is inconsistent with the enhanced greenhouse effect, they don't explain why.

    If their findings disagree with established science, its not in the lag during cooling, but rather in their assertion that CO2 levels rise in line with temperature during warming events.The long-standing explanations and understanding of CO2 concentrations don't actually disagree with the cooling lag at all.

    Take this article for example. Even in 2004, it was known that warming started (by whatever means), resulting in CO2 increases, which then created an amplification effect (feedback) leading to further warming. Cooling would work in a similar manner...cooling begins, leading to CO2 decreases, leading to further cooling....again an amplification effect.

    Here's another article which goes into more depth. It also explains why the notion of comparing interglcial timescales with historical timescales is flawed to begin with....as well as explaining why the lag you speak of doesn't contradict the current models at all.

    Note also that G&L claim on one hand that CO2 lags by up to 1000 years during cooling, and then go on to point to a drop in CO2 levels which coincides almost exactly with the Little Ice Age. Are they making an invalid association, or simply undermining their own claims of lag-time?
    I never claimed either were significant issues, and merely asked a question.
    And I pointed out that you either know the answer to your question (and are therefore being deliberately disingenuous), or you don't (and therefore show a basic lack of understanding of the models you are questioning).

    The answer to your question depends on which of those it is.

    The argument made by the IPCC is that, if we reduce our CO2 emissions, then the temperature will reduce after reducing our CO2.

    The evidence produced by Geerts and Linacre shows that, in the past, the CO2 reduces after the temperatures reduced.

    As we are trying to get the world to cool, do you not think it's more important to see what has happened in former cooling phases also, as this is what we are trying to achieve?

    Is it? Could you show me where they said that?

    My understanding is that the IPCCs position is that the more we reduce our emissions, the more we reduce the knock-on effects...which isn't the same thing.

    I'll see if I can dig up the link, but i'm pretty sure that the IPCC have, in fact, said we're already past the point where we could prevent any further warming impact, even if we cut all emissions to 0 tomorrow morning.
    The evidence produced by Geerts and Linacre shows that, in the past, the CO2 reduces after the temperatures reduced.
    The articles I've already linked to explain why the comparison of glacial-period time with historical time is invalid to begin with, so I don't understand what it is you're trying to say.

    Further, the idea that a global cooling event would cause CO2 to fall, which in turn would amplify the global cooling is in no way controversial. It is, in fact, logically consequent from the information presented in the articles I linked to...which date from well before G&L's work, and reference even older material.

    In short, there is no issue here.

    We're not trying to get the world to cool, though, so this argument is null and void.

    We're trying to limit the amount of warming we cause.

    you seem to understand that that is what I have said, as we seem to agree.

    So what? It's not relevant to our current situation.

    I would hazard a guess, that that is down to an increase of forestation and a decrease in desertification due to a cooler climate shrinking the subtropical arid zones.

    I understand what you've referenced. I don't understand what point you're trying to make....given that I've supplied counterpoints which explain why its not relevant to the discsussion of current climatological change, nor to short-term historical data.

    You ignored this, and simply restated the same point...which I don't understand.
    you seem to understand that that is what I have said, as we seem to agree.
    You agree that its irrelevant and inapplicable to the discussion at hand? Great....then we can both put it aside and move on.

    This is ridiculous. Every time one point gets disproven or explained away on the sceptic side, they just come back with another one, often unrelated or even contradicting what they said earlier.

    I don't understand how people can be dishonest and why they think they're fighting the good fight. What are they even fighting for?

    What ever happened to those leaked emails anyway? The story seemed to have just died after the Copenhagen thing was finished. Did anyone bother to keep track? I didn't, because I know it was just a media smokescreen.

    What are the "climate change" fascists fighting for?
    -"Climate Justice" i.e. socialism
    -Carbon Tax on everything
    -Carbon trading
    -Higher electricity prices to subsidize uneconomical (and unworkable) wind power
    -No motorways
    -No air travel
    -Turn everyone vegan
    -Force everyone to use public transport
    -Lower economic outputs (punish the west)
    -Waste taxpayers money on lowering the "carbon footprint" by building unwanted projects e.g. london-birmingham maglev

    Put simply, to reduce wasteful uses of energy (fossil fuel) before it runs out becomes uneconomical to extract and leaves us the rich people in charge in the lurch!

    In other words, we are expected to do without while the wealthy continue their wasteful way of life for longer.

    If you want to live in a socialist/fascist society please emigrate to China, North Korea or Venezuela. See how your quality of life improves.

    Fossil fuels and nuclear fuel is the most efficient use of energy. Ask Spain on their "wasteful" flirtation with non-fossil fuel energy.

    You clearly misunderstood the comment! Those things are happening in the west (here) right now!

    But I do agree with energy conservation through intelligent use of energy, otherwise there'll be none left for our children.

    The biggest issue we have now is the fact that oil is being stockpiled in places like China* and every barrel saved in the west is going east instead.


    *the fact is it's being stockpiled everywhere right now as the economy has stopped growing, but the price is still high/too high to allow growth.

    hmm are you talking about people going "without" their electricity connection (900 a month) because John Gormley raised the ESB prices to allow wind energy to be competitive?
