    Your article on Reykjavik prompted me to look at many arctic stations for which I had stored data last year. May i use the comparison figure in your article in mine? I will be putting it on TheNoTricksZone. I didn’t happen to store Raykjavik.

    Hi Paul,

    Have you ever seen or created – or do you know where the data is to do it – a scatter plot of power generated by wind (or % of capacity) against winter temperature? I assume the dynamics could well be different in summer.

    The whole idea of a power generation technology which does not actually produce power when it is most needed is fascinating.

    Great stuff, always useful. Have you seen the NIPCC site? This is not spam, I’ve been reading along and forwarding your pertinent (and often “pert”) questions to my AGW zombie friends. NIPCC generally has some pretty interesting links along similar lines culled from science publications. Great that there are places to find polite but serious questions about catastrophic AGW.

  7. February 11, 2013 4:20 pm links to your site’s Feb 8 blog. If I may, please allow me to point one other largely unreported facet of AGW, namely the baseless accusation that skeptic climate scientists are paid by the fossil fuel industry to lie about the issue. I wrote an exclusive for ClimateDepot nearly two years ago titled “Climate Depot Exclusive: “Smearing Skeptic Scientists: What did Gore know and when did he know it?” ( ), and the rest of my pieces on this narrow topic are here: “The ’96-to-present smear of skeptic scientists”

    Folks like me having no science background at all can contribute to a wider understanding of the politics surrounding the issue, at least.

    Is there a “tutorial” for lay people (albeit with an appreciation for science) that explores the AGW/CAGW controversy? My thought is an easily followed map that, step by step, follows the scientific method and general principles. One that shows how the science has been corrupted through each step of the scientific method and associated principles and continues to be supported with unfounded assertions and logical fallacies. Perhaps a tutorial that has citations and proof statements to support the assertions. I have a big file of papers/blogs etc on various positions on AGW/CAGW, I can grasp much of it but have limited capability to discuss it other than in generalities. Does such a tutorial exist or can someone write it up–again for the lay person with a grasp of scientific method.
    Regards and Thanks

      From the scientific point of view, the debate seems to revolve around two main issues:-

      1) What will feedbacks be?
      2) What will be the effects of a slightly warmer planet?

      There are certainly wide disagreements between scientists themselves about both these questions, but I am not aware of any write up that summarises everything.

      • April 24, 2014 10:37 pm

        I recommend, UN and UNEP websites, and the Club of Rome 1991 report “The First Global Revolution” as precursors to science. A step by step “procedure” to demonstrate how the scientific method would be used by researchers to determine the cause(s) of an observed climate change is a great idea, and an excellent way to highlight the contrast between scientific research and the propaganda we’re being inundated with . A compendium of the various methods that have been used to distort and misrepresent the science would be helpful, too.
        The most important issue in the AGW/CAGW controversy is that the concept that anthropogenic CO2 was affecting climate was proposed as a method to achieve political and economic goals. The corruption of the science and unfounded assertions and logical fallacies Ebeni mentions, as well as the severe weather events; earthquakes, typhoons and hurricanes of unusual magnitude, created or exacerbated by HAARP ELF and chemical dumps (Chemtrails) shown in satellite photos and radar, are essential means of achieving these goals. The major controversy is based on the fact that AGW isn’t science. Japan’s gosat satellite (greenhouse gas observing satellite) in 2009 showed that most CO2 was evolved from the ocean, sparsely populated vegetated areas in Africa, the Middle East, China, and northeast Asia, titled something like “need for economic justice from third world nations”.

      • April 24, 2014 10:50 pm

        Feedbacks alone are an issue, since nearly all feedback in natural systems is negative and maintains stability in the system, and IPCC predictions unaccountably assume positive feedback.

        The problem from any field geology or archaeology scientist’s point of the current science of climate appears to make no serious effort to determine what the geohistorical effects of similar or greater changes in the past were. There is quite literally no reliable empirical, field evidence that CO2 has any long term correlation to planetary temperature. At shorter, but still geological scales of time, the field evidence supports only the idea that warming oceans degas CO2. Warmer oceans CAUSE higher atmospheric CO2.

        Also, and worse, no effort is made to determine how patterns observable in the past, as reflected in geological data, would be seen in the present. Throughout the last quarter of the Pleistocene it is plain that CO2 lags marine temperature – or at least d-O18 changes – by several centuries. The implication is that if this pattern continued to the present, current increases in CO2 are due to events that took place during the Medieval Warm Period. We may very well have an effect on carbon isotope balances without significantly altering the efficiency of the carbon sinks that have been operating since life appeared on the planet.

        Those are important considerations, but I believe that the central issue is one of attribution, or whether there actually exists a distinct anthropogenic signal which can be isolated from natural variation. The sole argument for the anthropogenic signal comes from the models which ‘replicate’ the warming in the presence of CO2, but show a ‘flat’ line without. But the reason the line is flat is because of the working assumption that natural variation is random, not cyclic, and so the perturbations in individual model runs are smoothed out over the ensemble.

        I don’t doubt that anthropogenic CO2 is having some input, but the question remains about whether it is significant to the overall result.

      Ebeni, I my page “Observatorio ARVAL – Climate Change; The cyclic nature of Earth’s climate”, at I begin with:
      After the alarm caused by Al Gore’s film “An Inconvenient Truth” in 2006, these are my findings about the drivers of Earth’s global climate.

      I try to present this science in this long page.
      It is all about science published by well-known scientists, with links to the original works.
      As you can see below, I’m not a climate scientist, far from it. That’s why I had to do this research; To find out what happened, what is happening and maybe what could most probably happen. I hope you’ll find it interesting.

    New Anthony Watts Interview Just Published: Climate Change without Catastrophe (News Tip)

    Dear Shub,

    I just wanted to send you a quick mail to let you know that we have just conducted a very interesting interview with the well known figure in the climate debate Anthony Watts.
    It’s a very interesting chat and whether you agree or disagree with his comments I thought you and your readers would find some value in taking a look

    A few of the topics we discussed are:

    • The difference between “global warming” and “climate change”
    • Why CO2 is partially responsible but oversold
    • Why recent major weather events cannot be linked to CO2
    • Why we should be more worried about another ice age
    • Why carbon taxes won’t have any effect on the whims of Mother Nature
    • How the climate debate has taken on religious proportions
    • Why the Keystone protests are all for show
    • Why Mother Nature will be the final arbiter of truth
    • What we should and shouldn’t be doing to address global warming
    • Why “climate change” has become a favorite bogeyman
    • Why scientifically we’ve only scratched the surface of climate change

    You can read the full interview at:

    I hope you find the interview interesting.

    Best regards,

    “Because if you look at satellite data at the top of the atmosphere, you clearly see we have an excess of energy, more energy going into our planetary system then what is going out.”

    Hello Mr. Homewood,
    I did some datamining on a few British coastal weatherstations to see if the Atlantic Ocean is still warming.

    • June 3, 2013 5:14 pm


      I don’t know where he gets his data from, but Lindzen & Choi came to the opposite conclusion.

      There is certainly much debate about whether they are right or not, but I think it shows just how far away scientists are in being able to measure and understand such things.

      But the bottom line is that if Scnellhuber is right, the added heat would be measurable at the surface, which it is not.

    “The more I look at climate issues, the more I realise that we cannot always rely on what the climate establishment tell us.

    I hope that, in my own small way, I can help to put that right.”

    Well, Paul, that’s an admirable goal, but I have a couple of questions.

    1) Who are you – what are your credentials?

    2) Have you published anything in any peer-reviewed scientific publication?

    3) What is your academic background?

    4) What professional certifications, if any, do you possess?

    Don’t take this as a personal attack. It’s just that if I was going to have brain surgery, I’d really want to know that the surgeon who was going to perform the surgery was actually qualified to cut on me. It is no different with respect to the search for expertize in any field, for instance, in Climate science. And so I think you owe us a little information on your background.

    • June 27, 2013 6:50 pm

      Thanks for the question, Joseph, and I appreciate the reasons for it.

      However, I deal in facts. If you think I have made any factual errors, or misrepresented any issues, I would be delighted to discuss them with you.

      As I am sure you would agree, Climate Change is an enormously important area of public policy and debate, and I believe that the more facts that are out in the public arena, then the better.

      One more point, and perhaps the most important. I always encourage people to do what I have done, and check the facts for themselves, rather than simply believe what they are told. So I usually try to provide links etc for readers to do just that.

    Paul: here is an interesting discussion I had with a few folks tonight.

    The hottest year in the U.S. was 1921. 1934 was second. The average temperature for the 48 contiguous states in 1921 was 55.6°F. To confirm this one can read the first paragraph of THE WEATHER OF 1940 IN THE UNITED STATES (W.W. Reed) or THE WEATHER OF 1942 IN THE UNITED STATES (J.L. Baldwin).
    The average temperature in 1934 was 55.1°F. The original temperature measurements published each month for each state for those years by the U.S. Weather Bureau will add up correctly.

    BTW… Two-thirds of the state record high temperatures in the U.S. were recorded before 1955. More than half were recorded from 1921-1934. Few have been recorded since 2003. Yes, it is warming today, but it also did so during the first half of the last century… and at about the same rate

    OK. Here are some numbers. The first column shows weighted monthly temperatures for the 48 contiguous states (no Hawaii or Puerto Rico) derived from the original 1921 US Weather Bureau monthly reports… the Tables in the Condensed Climatological Summary. Example:
    The average temperature (°F) for each state is given in these official reports. Only the contiguous 48 are used. The second column gives the temperatures from the NCDC-NOAA 1895-2009 US database where, presumably, the same historical information is given for each state, each month. The third column is the amount that the NCDC has lowered each temperature.

    JAN 36.0 33.8 2.2
    FEB 38.5 35.9 2.6
    MAR 49.5 47.5 2.0
    APR 53.7 52.2 1.5
    MAY 61.9 60.5 1.4
    JUN 72.1 70.8 1.3
    JUL 76.1 75.3 0.8
    AUG 73.0 71.6 1.4
    SEP 69.0 67.7 1.3
    OCT 56.4 54.9 1.5
    NOV 44.7 42.9 1.8
    DEC 36.7 34.5 2.2

    YEAR 55.6 53.9 1.6

    Note that the annual average for 1921 has been lowered by 1.6°F. This lowering has the net effect of removing the year 1921 from its position as the warmest year on record in the US… as the Weather Bureau observed in several annual reports I cited earlier. The same pattern of lowering can be found in other years. I’ve checked 1934, 1938, 1940. All of the original Weather Bureau temperatures have been systematically changed and all have been lowered. The winter months have been lowered more the summer months…every time….WHY?

    • April 25, 2014 9:27 pm

      “The winter months have been lowered more the summer months…every time….WHY?” Lowering summer month temperatures creates the impression of recent warming. Lowing historical winter temps supports the alarmist sea-level rise, catastrophic flooding meme by making current winter temps appear unusually warm, supporting predictions of a trend toward unprecedented glacier and polar ice melts. My guess, anyway.

    There is not much actual physical facts being used in climate science.
    They just have been following temperature data for the last 150 years and tweaking in garbage and calling it a model.

    Facts are completely irrelevant.
    Hunting for any pattern to call a trend in a system that is in completely unique every moment and every place. Never to find that exact pattern. All of this is irrelevant to the many processes and material differences in play on a rotating planet that has many different velocities with many different pressure differences on an ORB.
    Any mathematical equation is pure horseshit as they all assume a single point that does not interact or move. PI(3.14159) was never designed for motion and every rotation after the first distorts due to the equation being open ended.
    We have NEVER measured distances of a fantastic amount of planetary data that gives some understanding to how this planet actually mechanically operates. The gas of nitrogen being 80% interacts against water vapor and does so much more to moving water vapor in creating snowflakes and keeping water vapor separated and changes density with the cold.

    In simple terms…

    Our planet is getting colder due to the suns inactivity which gives off great amounts of material that our atmosphere has lost catching in the last decade to insulate the planet with the gases by the thickness. We are in constant loss of material including water vapor over 4.5 billion years.

    There is vast amounts material and questions to understand by pure facts. All the answers ARE here, just our scientists have gone on a different direction and will protect the garbage to the bitter end and keep the citizens ignorant.

    1) thanks for your site which has become my 1st visit on most days, usurping WUWT, mainly due to your UK emphasis.
    2) it may be my workstation today, but I note that comments aren’t available and also you appear to have lost your google ranking from my search protocol in that I do not get your site offered when searching on ” not a lot of..” where previously those four words initiated a direct link being offered. Hmmm – do these indicate some google-filtering? Could be worth a check.
    3) I live in Morayshire, Scotland. The Scottish Government have adopted even more banzai climate madness policies than their UK/English & Welsh counterparts. Should you ever have time, it would be interesting to have a column or posting dealing with Scottish issues – especially as the looming referendum draws near.

    Paul – your post about the EADT article I tipped you yesterday has created a bit of an opportunity. One of my friends has emailed the editor and linked to your article. He particularly challenged the use of “Carbon” pointing out that it was a meaningless term, that they should have used CO2, and how this was only a tiny percentage of the atmosphere.

    He’s just had a response from the editor inviting him to submit a reply or article, and thinks you would be able to produce a far better answer than he could. As I can’t find a direct contact on your site, would you be good enough to email me (at the address on this post) and say if you are prepared to help? If you are, I will put you in touch with my friend and he can pass on the correspondence so far.

As for John Gibbons it is nothing unexpected – I filled in someone else recently that the Irish Times allows columnists such as John Gibbons write pseudo-scientific nonsense and rarely prints corrections or dissenting opinions.

    Dear Paul,

    Your site is fascinating – thank you for all your work, and for my education.

    I have a question about the recent UK rainfall articles you’ve written using Met Office data.

    The articles are very clear as always, but can the data tell us anything about rainfall intensity, by which I mean lots of rain falling in a very short time?

    This is always the response to the argument that rainfall totals are not all that exceptional. It’s also where the Met Office seem (to me) to be going (i.e. that the new improved models show increasing and more intense regional weather effects).

    Clearly the effects of a given total of rainfall will be very different if spread over three months rather than one, but presumably a really wet year like 1929/30 must have had rainfall at least as intense as we’re now experiencing?

    Is it just as simple as saying that “rainfall intensity” is directly related to the amount of rainfall in a period, therefore that it cannot really be varying as is incessantly claimed? Flash floods and local geography (Boscastle/Seaton) excepted of course.


    Steve Brown

    • February 14, 2014 10:20 am

      The Met Office do keep rainday data, so you can work out daily averages. However, this only starts in 1961, which coincided with an unusually dry couple of decades. Therefore, any trends are unreliable.

      I did do an exercise that used daily rainfall data on the England & Wales series, that records it since 1931. The exercise showed quite clearly the dry interlude (with fewer heavy rainfall days), and suggested that the last decade was no different to 1931-60.

    Hi Paul
    Had a couple of thoughts that I can’t find the answer – wondered if you might know!
    1. What is the cost to maintain a wind turbine?
    2. I am assuming that wind turbines are subsidized in a similar manner as solar pv and that the subsidy only lasts for 25 years. At the end of that time the wind “farmer” I presume, get the going rate per kwHour at wholesale rates (solar pv get 4.5p per kw). If so what is the actual average output of a turbine and will it be sufficient to cover the maintenance costs?
    3. I just have a vision of lots of broken wind turbines in 25 years time that have become uneconomic to be fixed and that the wind farmers will just abandon them and build another turbine nearby to get the green subsidy again for another 25 years.

    Wouldappreciate your thoughts/figures?

    • April 9, 2014 10:52 am


      The subsidy for wind turbines will be for 15 yrs, under the new strike price contracts.
      I don’t know mtce costs, but such marginal costs would bge fairly low – most of the cost is the upfront capital cost.

      In theory, the planning process should ensure that they are properly decommissioned, but in practice what will happen if the operator just walks away?

    Paul, I know your beat is weather history, so this is “off topic” a bit. I ran across information about a remarkable Englishman, a veteran of World War I. I believe I read he was England’s most decorated solider in that war. Being from the states, perhaps is why I have never heard of William Coltman before. Have you? Its just interesting. Here a couple links to biographical material. I didn’t see any books.

    I do appreciate your work. No conversation about weather or climate is even coherent without a firm grasp of past observations. Its preposterous to model the future without apprehending the past.

    Hi Paul,

    Have been following your blog for some time now and have recommended it to numerous people.

    I wonder whether you might be interested in this article discussing the potential impact of climate change on the medical profession and what their ethical response should be. I came across this in the Student BMJ (my daughter is in her third year) and here is an online link:

    You need to register (for free) to read the full article.

    This is a good example of the way climate change has insinuated itself into every thread of discourse in modern life and is described as fact by someone who clearly has no knowledge of the subject he is pontificating on but is driven by the collective groupthink that pervades this topic.

    Doctors and nurses have enough to worry and should (and probably do already given lack of comments) ignore exhortations to take part in a phoney war on climate change.

    Hi Paul,

    In researching the recent Facebook psychological experiment scandal I came across this article about filter bubbles:

    Nothing really surprising but in combination with the fact that Facebook have been manipulating the bubble to see the effects (without our knowledge or consent) one quickly realises the potential ramifications in terms of its misuse being able to influence what we think, buy and more scarily, vote.

    Clearly none of us can escape from this if we spend any time on the internet and it does help to explain why a dangerous meme like CAGW takes hold so perniciously. A little depressing but I do wonder whether like the butterfly effect, there might sometime soon be a chaotic switch which consigns that meme to the dustbin of failed ideas. One can only hope!

    I continue to share your posts with family, friends and colleagues but with little feedback. It would be interesting to know what influence your other readers have in this respect? I suspect several of my “friends” have already set their Facebook filters to quietly hide my posts!

    I have developed something that could be of interest. It’s a way of doing temperature trend analysis that neatly avoids all the data manipulations so much discussed recently. I have built an Excel workbook for this method, and have done a study of Kansas US in order to prove the concept and the tool.

    At this point I need someone with a skeptical mind to critique what I have done. If you are willing I can email you the Kansas workbook and you can see if it stands up to scrutiny.

    I have started building a Canada workbook with this template, but there are many stations, and it will take time. I also want to verify that I am on the right track before making the full effort.

    I can also send a text document explaining the rationale for temperature trend analysis.

    Please let me know what you think..

    Paul – you may like to publicise this…

    Or you may not! However, I thought I’d bring it to your attention

    Classify the terms “denier” , “climate denier” or variants thereof as hate speech.

    Paul. See if you can access Sheffield Weston Park Weather Station records. You might have to make a trip to the museum…..

    130 Years of history

    Its situated at almost exactly the same position for that time.

    It MUST be one of the longest sited class A weather stations in the world.

    There isn’t much development around the site which would change the conditions.

    It would make a cracking blog post.

    I bet you ANY money it doesn’t show dangerous warming.

    Then see how this raw data compares with NASA, GISS and the like. There should be any adjustments really at all on it.

    Hi Paul

    Earlier this week the BBC website carried a piece by David Shukman on ‘the pause’ – as I recall, it was notable insomuch as not entirely discounting natural cycles as playing a role. It was at least questioning which surprised me given the BBC’s biased policy on the subject of anything to do with climate change. Anyway – having only initially skimmed through the article I returned to it the following day to find that it had vanished. Did you see it or did anyone else see it or was I dreaming or is it another example of BBC censorship at its ugliest?

    Hi Paul,

    you may be interested in this link, commentary on the “landmark” deal between the US and China, which I had understood not to be that significant reading between the lines. However, this chap thinks it is a real step towards saving the world:

    Had an interesting real-world demonstration of UHI yesterday. Was driving south from Green Bay, Wisconsin USA in a snow squall, temps just below freezing. Hit Milwaukee, approx. population 1 million, snow turned to light mist – temps just above freezing. Kept going same highway south of Milwaukee, snow squall again. hmm.

    More cobblers from the Conversation:

    Some of your favourites here Paul: steam cooling image, “carbon” emission, comparing their new equation to models, no hint of reality creeping in anywhere as far as I can tell.

    I think I need to cancel my subscription to this idiotic publication before I blow a gasket.

    Thanks, Paul. I (a layperson re climate studies) intend to read carefully and check what I can. I think I followed links to you regarding her Figure 14 “Carbon Dioxide and Temperature: An Unnatural High” (in the glossy sheets tipped in halfway through the book). it gets hammered by critics for minimizing (I guess) both temperature and CO2 highs some seem to know of within the last 6000 years (the span of her Figure). If you can point me to a more accurate historical reconstruction of those, I’d be grateful.

    Paul, I think my comment went to the “spam” folder (probably because it has lots of links):

    Sorry to post this here; I couldn’t find contact info for you. Would you mind sending me an email, so that I can email you privately next time?

    For a long time I’ve been concerned about the scientific method used in climate science (and indeed all endeavours that aim to call themselve sciences but are not.) Rather than comment myself, here are some relevant quotes from probably the greatest philosopher of science in the 20th century, Karl Popper:

    “Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.”

    “True ignorance is not the absence of knowledge, but the refusal to acquire it.”

    “But the secret of intellectual excellence is the spirit of criticism ; it is intellectual independence. And this leads to difficulties which must prove insurmountable for any kind of authoritarianism. The authoritarian will in general select those who obey, who believe, who respond to his influence. But in doing so, he is bound to select mediocrities. For he excludes those who revolt, who doubt, who dare to resist his influence. Never can an authority admit that the intellectually courageous, i.e. those who dare to defy his authority, may be the most valuable type. Of course, the authorities will always remain convinced of their ability to detect initiative. But what they mean by this is only a quick grasp of their intentions, and they will remain for ever incapable of seeing the difference.”
    ― Karl Popper, The Open Society and Its Enemies, Volume 1 : The Spell of Plato

    “The more we learn about the world, and the deeper our learning, the more conscious, specific, and articulate will be our knowledge of what we do not know; our knowledge of our ignorance. For this indeed, is the main source of our ignorance – the fact that our knowledge can be only finite, while our ignorance must necessarily be infinite.”

    “The game of science is, in principle, without end. He who decides one day that scientific statements do not call for any further test, and that they can be regarded as finally verified, retires from the game.”

    “In so far as a scientific statement speaks about reality, it must be falsifiable: and in so far as it is not falsifiable, it does not speak about reality.”
    ― Karl Popper, The Logic of Scientific Discovery

    “The discovery of instances which confirm a theory means very little if we have not tried, and failed, to discover refutations. For if we are uncritical we shall always find what we want: we shall look for, and find, confirmation, and we shall look away from, and not see, whatever might be dangerous to our pet theories. In this way it is only too easy to obtain what appears to be overwhelming evidence in favour of a theory which, if approached critically, would have been refuted.”
    ― Karl Popper, The Poverty of Historicism

    “With the idol of certainty (including that of degrees of imperfect certainty or probability) there falls one of the defences of obscurantism which bar the way of scientific advance. For the worship of this idol hampers not only the boldness of our questions, but also the rigour and the integrity of our tests. The wrong view of science betrays itself in the craving to be right; for it is not his possession of knowledge, of irrefutable truth, that makes the man of science, but his persistent and recklessly critical quest for truth.”
    ― Karl Popper, The Logic of Scientific Discovery

    “We all have an unscientific weakness for being always in the right, and this weakness seems to be particularly common among professional and amateur politicians. But the only way to apply something like scientific method in politics is to proceed on the assumption that there can be no political move which has no drawbacks, no undesirable consequences. To look out for these mistakes, to find them, to bring them into the open, to analyse them, and to learn from them, this is what a scientific politician as well as a political scientist must do. Scientific method in politics means that the great art of convincing ourselves that we have not made any mistakes, of ignoring them, of hiding them, and of blaming others from them, is replaced by the greater art of accepting the responsibility for them, of trying to learn from them, and of applying this knowledge so that we may avoid them in future.”
    ― Karl Popper, The Poverty of Historicism

    Linked to the manipulation of the climate change agenda is the need for its supporters (now including all meteorological services and nearly all politicians) to convince the public of its supposed impact. Over the last year or two (at least in the UK) I’ve noticed an escalation in the language used in weather bulletins. Two examples spring to mind: “Weatherbombs” and “Embedded Thunderstorms,” both of which have connotations with terrorism, and lead to the thought: “Who or what is responsible?”

    The answer is easy – climate change of course!!

    Paul, The Canadian Newspaper, the globe and mail, has an informative article re the honest volunteers across Canada who record temperatures from their Stevenson screens daily. Do you know if Canadian temperatures are manipulated like the ones from S. America and Iceland that you recently reported?

    Hi Paul,

    Hot off the press from the BBC web site: . Talking about 128mm rise in sea level north of New York city.

    Hi Paul,

    You may be interested in developments in Australia. A group of us has for some time been concerned about the homogenization of the very good raw temperature record for many parts of Australia. Late last year, after much disquiet, the government finally established a panel to oversee what out Bureau of Meteorology has been up to with all the ‘adjustments’.

    So far this new panel has not asked for our opinions, but we have nevertheless made unsolicited submissions. You can read them here…

    And you will get some idea of the extent of the problem with the official Australian temp. record.

    You might also be inclined to make a submission to this panel, and if you do, please send me a copy so I can upload to this page.

    Indeed it would be good if the panel was given some idea of the extent of the problem internationally.

    Cheers, Jennifer Marohasy

    Have you seen this report?

    It includes this from leading Yale researcher Anthony Leiserowitz: “Indeed, many people were a bit surprised to find that global warming was not, in fact, a myth; and more importantly, that the state of global warming was nearing critical mass and we are now in a place where we must make drastic changes or face equally dire consequences.

    The Yale Project on Climate Change Communication lead researcher continues, “There have been a number of studies that have shown that some people will change their views of climate change based on extreme weather. It’s not enough to simply experience a heat wave — it then needs to be contextualized. It needs to be interpreted by thought leaders and trusted people in a community and by the media and scientists saying, ‘This is an indication of global warming.’”

    So dismiss the fact that it is just a theory, not fact, and use any extreme weather event to support the theory. Dishonest or what?

    When will our academics understand that scepticism, rigour and honesty are the foundations of science?

    I’m not sure if you picked this up:
    Penultimate paragraph:
    There’s much to learn from extremophiles living deep below Earth’s surface or seabed. For one, because these organisms feed on hydrocarbons, they produce methane as a byproduct which is a greenhouse gas thousands of times more potent than CO2 at trapping heat. How many of these organisms are there below the oceans? Billions, trillions, billions of billions? We need to know if we’re to build a solid model that faithfully assess their impact on the climate.

    We can’t even model the global economy and get it right, and that’s a human construct orders of magnitude simpler than the climate system
