    “gets a bit foggy really” NO it does not hainy you actually selectively quote and misuse Proff Latif the man who keeps complaining to the media about climate sceptics misquoting and mispresenting his work.

    You also managed to omit some relevant text from your post
    “Professor Latif is based at the Leibniz Institute of Marine Sciences at Kiel University in Germany and is one of the world's top climate modellers.
    But he makes it clear that he has not become a sceptic; he believes that this cooling will be temporary, before the overwhelming force of man-made global warming reasserts itself.”

    I understand Junykards view point. He is saying that there is more CO2 now than there ever has been, ergo temperatures will keep rising and we will break the natural cycle

    Well that's not really a fair reading. The nuts and bolts of it is thus:

    CO2 has a big effect on global climate amongst many other factors. Humans have released tons of CO2 into the atmosphere which threatens to warm the planet on average and throw the climate we've grown up with into a cocked hat. Wiping out crops in areas where living is marginal and so on.

    Now it's true that this has surely happened before, but now a lot more is at stake, and also we might also be able to stop it happening, or limit its effects, by not being so disgracefully wasteful.

    These theories have been arrived at after years of intensive study. So it's not really fair to say 'well I don't think so' and that's that.

    Yes, it's all foggy, of course it is. Science is foggy most of the time. But that doesn't mean that it's invalid or all rubbish. Scientists investigate, learn, create theories (or models in this case) and then test them. And in the process, develop understanding. What's more, they all understand this scientific process. The problem is that the media just blurt out condensed soundbites that often give out the wrong idea.

    Most climate scientists are very worried that anthropogenic CO2 could have a drastic effect on climate because all their research tells them so. So surely, we must all be concerned too? I mean what if they are right? I for one surely don't know enough about the subject to disagree with them, and my feeling is really that you don't either.

    After all, an intelligent many knows what he doesn't know.

    As I said, everyone is entitled to their opinion, that is why it is such a heavily debated topic and why there are so many scientists on both sides of the fence arguing the science. I for one hope they can stop climate change (notice i didn't say man made).

    Yeah but it's more than just opinion mate. I think some on this thread have taken offence to someone holding an opinion that doesn't seem to them to be based on science. Plus you were telling them they were wrong a bit 🙂

    Also, even if you suspect CC not to be man-made I hope you are still taking steps to reduce your energy consupmtion anyway, just in case!

    When i say ripped apart, i really meant dismissed without any real reason.

    But anyway, people have chosen not to debate the historical CO2 and temperature levels, the complex interaction of CO2, Water Vapour and Methane, our over-reliance on beef and what should be done about that so if people won't engage then fair enough.

    I'm sure everyone is bored so lets just agree to disagree and hope that Scientists are clever than we think and can stop the next ice age.

    Just to move the debate on a bit, do you have any ideas as to how "they" might do this?

    Absolutly no idea – I for one think its impossible.

    That's what climate scientists do all day! I've read loads on those things. We've debated it lots on this thread for starters.

    our over-reliance on beef and what should be done about that

    Again, widely discussed. I've read many times that to feed a person on beef requires something like 7 times more grain than to feed a person on grain.. Some politician was telling us just a few weeks back that we should be vegetarian, and I think someone has a guideline out that suggests we give meat a miss one day a week. The effect of cow farts on climate is major issue as is the deforestation that comes with large scale beef farming in the developing world.. lots and lots of stuff.

    Actually Hainey – I think the biggest problem is that AGW theory is based on faith, with science used to back up the argument.

    The "faith" is that we, as a race, are damaging the planet, the "green lobby" have been banging the drum calling for changes for years, and have discovered that AGW is a very effective rallying cry – I don't really think that as a race we've come that far from the days of thinking that we have angered the gods who are punishing us with a storm.

    I haven't actually seen anyone here take issue with the facts that data has been manipulated, that there are proven differences in sets of data that can only be explained through recording/processing bias, that there is contradictory data that is being ignored – quite simply, thats not good science – QA the data, and see whether the data still fits the theory, if it does, great, if it doesn't, then you have to revisit the theory – thats simply not happening.

    I'm not saying that there isn't a very fair argument for cutting back on consumption, pollution and damage – however the science being performed in the name of AGW is really pretty poor, its a classic case of making the evidence match the theory rather than the other way round.

    If there was some kind of super effective green lobby that was able to persuade governments what to do (HAHAHAHAHA!!!) then surely they would think of a more effective tool of persuasion than some nebulous future concept that really won't affect much the people who are most able to affect it at some unspecified point in the near or far future.

    Something like save the rainforest, tigers, elephants, bears etc would have been far more effective don't you think?

    I personally think that the likes of Michael Moore and to a lesser extent Al Gore have done a major disservice to the cause by trying to sensationalise AGW.

    Can someone post or re-post a cication for poor science, I haven't time to read the whole thread.

    I think its a psychological issue thats built deep in human society!

    It's been demonstrated in a huge variety of differing cultures since time immemorial, that where there is chaos we seek order and control, and where there is an event which we cannot explain we seek a reason why – human sacrifices to appease the angry volcano gods, kings seeking to control the tides, and the very source of a whole variety of religions from paganism to christianity!

    Is it really so different, have we really come on so far as a race that we now think that we can control our destiny?

    Hainey said:

    But anyway, people have chosen not to debate the historical CO2 and temperature levels

    Hainey, that is so not true that I'd have to call it a bare-faced lie.

    Sorry to bore everyone else again but here is a very good explanation for the cyclical nature of historical CO2 and temperature levels:

    The coolings appear to be caused primarily and initially by increase in the Earth-Sun distance during northern hemisphere summer, due to changes in the Earth’s orbit. As the orbit is not round, but elliptical, sunshine is weaker during some parts of the year than others. This is the so-called Milankovitch hypothesis [this really should say "theory" — eric], which you may have heard about. Just as in the warmings, CO2 lags the coolings by a thousand years or so, in some cases as much as three thousand years.

    But do not make the mistake of assuming that these warmings and coolings must have a single cause. It is well known that multiple factors are involved, including the change in planetary albedo, change in nitrous oxide concentration, change in methane concentration, and change in CO2 concentration. I know it is intellectually satisfying to identify a single cause for some observed phenomenon, but that unfortunately is not the way Nature works much of the time.

    Nor is there any requirement that a single cause operate throughout the entire 5000 – year long warming trends, and the 70,000 year cooling trends.

    Thus it is not logical to argue that, because CO2 does not cause the first thousand years or so of warming, nor the first thousand years of cooling, it cannot have caused part of the many thousands of years of warming in between.

    Think of heart disease – one might be tempted to argue that a given heart patient’s condition was caused solely by the fact that he ate french fries for lunch every day for 30 years. But in fact his 10-year period of no exercise because of a desk job, in the middle of this interval, may have been a decisive influence. Just because a sedentary lifestyle did not cause the beginning of the plaque buildup, nor the end of the buildup, would you rule out a contributing causal role for sedentary lifestyle?

    There is a rich literature on this topic. If you are truly interested, I urge you to read up.

    The contribution of CO2 to the glacial-interglacial coolings and warmings amounts to about one-third of the full amplitude, about one-half if you include methane and nitrous oxide.

    So one should not claim that greenhouse gases are the major cause of the ice ages. No credible scientist has argued that position (even though Al Gore implied as much in his movie). The fundamental driver has long been thought, and continues to be thought, to be the distribution of sunshine over the Earth’s surface as it is modified by orbital variations. This hypothesis was proposed by James Croll in the 19th century, mathematically refined by Milankovitch in the 1940s, and continues to pass numerous critical tests even today.

    The greenhouse gases are best regarded as a biogeochemical feedback, initiated by the orbital variations, but then feeding back to amplify the warming once it is already underway. By the way, the lag of CO2 of about 1000 years corresponds rather closely to the expected time it takes to flush excess respiration-derived CO2 out of the deep ocean via natural ocean currents. So the lag is quite close to what would be expected, if CO2 were acting as a feedback.

    The response time of methane and nitrous oxide to climate variations is measured in decades. So these feedbacks operate much faster.

    The quantitative contribution of CO2 to the ice age cooling and warming is fully consistent with current understanding of CO2’s warming properties, as manifested in the IPCC’s projections of future warming of 3±1.5 C for a doubling of CO2 concentration. So there is no inconsistency between Milankovitch and current global warming.

    It's an extract form an earlier posting. Have you read it?

    RPRT – rather than just cutting and pasting from realclimate, can YOU debate it?

    edited to add: I mean, this is half the problem – rather than looking at the data and facts and actually thinking about it themselves with a critical mind, most of the people on here are simply parroting someone else's opinion and telling us that the "consensus" must be right, simply because its the consensus!

    I haven't actually seen anyone here take issue with the facts that data has been manipulated,

    a number of us objected to you doing it with your graph/correlation is that the kind of manipulation you mean? I find it very difficultto have a discussion with someone about data manipulatuon when they did that and then repeatedly called a graph of factors over time a correlation. You pretty much discredited yourself there IMHO.

    How much more data do you want have you seen how much is in the IPCC report? Why is it bad to reference to other people – have you ever read a science paper it is an essential part of any research.

    You see junkyard – this is another part of the problem, you don't understand that I didn't do ANYTHING to alter the data, just express it in a less sympathetic way than your own graph – was your own graph right, or was that manipulated by someone to prove a point on skepticalscience where you cut and pasted it from?

    No you dod not manipulate the data you used a rathe odd choice of scale. The data was unaltered the presentation was – you call it less sympathetic everyone else asked why you use the same scale for C02 and ppm you did not answer iirc – care to explain now?
    reread they consensus on that.
    Did anyone on here actually defend that graph other than you?
    Did everyone who commented it criticise it for the same reason [scale]?
    Did you repeatedly mistake it for a correlation?

    Everyone was scathing of that graph are we all wrong and you are the lone voice of reason?

    Yeah, you're persuaded by the argument, but not by actually questioning it critically and looking behind the argument.

    It was fairly clear that the argument that Saddam had WMD persuaded a huge proportion of our politicians that it was true, and that action was necessary, the arguments were really strong with lots of facts to back them up, there was a consensus among the intelligence community who were all experts in the field…

    look where that got us!

    Edited to add – I'm afraid you might want to look at what I actuallysaid Junkyard.

    Was your graph from Skepticalscience any more reliable or a better use of the same data – was it any more accurate, seeing as they had to factor the data to form the curve – it was a simple exercise in how you can present data to prove or disprove your point!

    That's a really bad annalogy the consensus in the inteligence community appears to have been there was no significant evidence of current WMD that's why the particular politicians who wanted to go to war needed a dodgy dosier based on a google search. The argument that pursuaded the MP's appears to have been an assurance from the sitting PM that he had seen the secret evidence and they should take his word for it .

    The historical time periods being evoked over the last few pages are far to short if we are looking for the conditions we can expect as we rise beyond atmospheric carbon levels of 380ppm. 500ppm is a realistic estimate of what we will reach in the not too distant future so shouldn't we be looking at conditions that correspond to those levels?

    Well a couple of points there, so firstly,

    You said:

    Yeah, you're persuaded by the argument, but not by actually questioning it critically and looking behind the argument.

    You mean I disagree with you?

    Then you said:

    It was fairly clear that the argument that Saddam had WMD persuaded a huge proportion of our politicians that it was true, and that action was necessary, the arguments were really strong with lots of facts to back them up, there was a consensus among the intelligence community who were all experts in the field…

    Firstly, what the hell do you think this proves? You're the one telling us to look at the data for ourselves, don't accept anything that isn't utterly objective and verifiable, and yet you think that comparing the controversy over Iraq with the controversy over climate change somehow strengthens your case?

    But secondly (as you mentioned it) what an incredibly poor choice of metaphor.

    Actually before the Iraq invasion the UN weapons inspectors – in your analogy, lets think of them like the climate scientists – said that there were no weapons.

    But the armchair experts, (neocons hardliners G W Bush etc, Dick Cheney etc), in your analogy – lets think of them as the climate deniers (oh hang on, THEY ACTUALLY ARE THE SAME PEOPLE!) – said that there were obviously weapons.

    In other words, the "analysts" back home were wrong and the "scientists" on the ground were right.

    So how is that a good metaphor for the climate change argument again?

    Didn't anyone hear Hans Blix when he said he had visited all the sites he had requested access to and found nothing. Just the information Blair need to go in knowing he had nothing to worry about. That his troops wouldn't be poisoned and Israel wouldn't be nuked.

    (Apologies for sidelining the discussion)

    You see RPRT – you do it again, jump to conclusions and misquote people – I didn't say anything about the UN weapons inspectors, I said there was "consensus among the intelligence community who were all experts in the field"

    Actually, Hans Blix said nothing of the sort at the time – He said more research needed to be done, he quite categorically did not say there were not any weapons

    http://www.un.org/Depts/unmovic/SC7asdelivered.htm

    In fact, if anything, its more accurate to put Hans Blix in the "skeptic" position – his position was that the evidence was inconclusive, that a lot of the evidence being used was unreliable, and he went away to encourage actually inspecting, rather than relying on "consensus" arguments and probabilities based on historical data!
