									Government should re-examine the climate
data

TWO recent, widely publicised reports by the government's scientific advisory agencies
on climate change have sought to raise alarm yet again about global warming.

With the world having warmed slightly during the late 20th century, CSIRO, the Bureau of
Meteorology and the Climate Commission all advocate that this warming was caused mainly
by industrial emissions of carbon dioxide, and that the continuation of emissions unchecked
will cause dangerous warming of 3C-4C by 2100.

However, these and other climate agencies are now encountering a public that is increasingly
aware of the lack of factual evidence for dangerous warming, and of the speculative nature of
the arguments advanced in its favour.

For example, many people now understand that there is no direct evidence that 20th-century
warming was caused mostly by carbon dioxide increase; that the late 20th-century warming
has been followed by a 15-year temperature standstill in the face of continuing increases in
carbon dioxide; and that the models that project alarming future warming are inadequate.

The dangerous warming hypothesis is embodied in the complex climate models that CSIRO
and others use to predict the future climate.

But when the model predictions are tested against the latest high-quality data from our best
instruments, they are seen to have comprehensively failed.

For example, the models predicted increasing global air temperatures (the measured rises
have been much less than predicted), increasing ocean temperatures (there has been no
change since 2003, when we started measuring it properly with Argo ocean-diving buoys)
and the presence of a hot spot caused by humidity and cloud feedback at heights of 8km-
12km in the tropical atmosphere (entirely absent).

The last item is especially important because it shows that the crucial amplification assumed
by the modellers and which is responsible for two-thirds of the predicted warming (yes, only
one-third is directly due to carbon dioxide) simply does not exist.

Finding that the estimated historic increase in carbon dioxide was not enough to cause
dangerous warming on its own, the modellers guessed that atmospheric water vapour would
amplify, by a factor of three, any initial carbon dioxide-forced warming.

That this assumed amplification is present in the models but not in reality explains why the
models consistently overestimate recent warming.
What then should our government be making of all this?

Well, the government appears to take advice on global warming and climate change from a
wide range of sources, which include the UN Intergovernmental Panel on Climate Change,
Australian government agencies (CSIRO, BOM), state-based greenhouse or climate-change
bodies, rent- seekers from many university climate-related research groups, business lobby
groups and consultants and, finally, large environmental lobby organisations (Australian
Conservation Foundation, Greenpeace, WWF). Phew.

The reality is, though, that all of these groups and organisations take their lead from, and
support the views of, the IPCC (a political body that is unaccountable to Australian citizens).

Their starting assumption is therefore that human-caused global warming exists, that it is
dangerous and that the way to avert the danger is to "decarbonise" the planet. The many
agencies and groups giving advice are, in fact, just providing multiple conduits for the same
repetitive, alarmist message, which derives ultimately from the same IPCC source.

Since the government's carbon tax legislative package passed the Senate last October,
Australian press coverage of the global warming issue has been muted, doubtless partly
signifying that there have been few government media releases that address the topic since
the Senate decision.

That situation changed with a jolt during the week starting on March 12, when a wide variety
of news media carried stories about CSIRO's Cape Grim air pollution monitoring station in
Tasmania, followed later in the week by publicity for new reports on global warming by
CSIRO/BOM and the Climate Commission.

In effect, the week revealed a co-ordinated and highly successful public relations campaign
by three of the organisations involved in giving advice on climate change in Australia, with
support and advance knowledge among some media editors and reporters. The aim was to
rekindle the fast-fading fear of global warming alarm among the general public.

Very little scientific balance or analysis was provided during this week-long barrage of tired,
speculative and highly controversial assertions about supposedly dangerous global warming.

Rather than being a new state of affairs, this assault in favour of warming alarmism by
Australian climate agencies follows many similar propaganda blitzes during the past 10
years.

As experienced scientists, we have just completed a detailed assessment of the recent reports,
which has been added to the list of earlier independent audits of IPCC and Australian reports
at Quadrant Online (Google "global warming: an essential reference").

Our analysis of the "new" reports finds that they provide no evidence that dangerous global
warming is occurring; nor that human carbon dioxide emissions will cause such warming in
future; nor that recent Australian climate-related events lie outside normal climate variability;
nor that reducing carbon dioxide emissions will have any discernible impact on future
climate.
Therefore, Australian public policies regarding dangerous climate change, sea-level rise and
other climatic hazards are based on inadequate scientific advice, which is shackled to the
shortcomings of inadequate computer model projections.

The climate models are incompatible with the measured data. In recent decades the model
predictions have significantly exceeded the measured temperature rise.

In science, data trumps theory. If data and theory disagree, as they do here, scientists go with
the data and revise their hypothesis.

But in politics the opposite is true, for authority figures and political correctness reign
supreme. In which context government climate scientists, Western governments and
numerous influential lobby groups all strongly support the idea of dangerous global warming,
despite the strong contrary evidence.

We conclude that an obvious and urgent need exists for the government to reassess its climate
hazard policies. A good starting point would be to implement an unbiased review of the
evidence.

       Thanks to Bob Carter and his associates for explaining the reasons why Global
       Warming has simply not occurred as the IPCC and CSIRO models say it should. You
       cannot argue with good data and unbiased science. This should reinforce Tony
       Abbott's intention to repeal the carbon tax legislation and other irresponsible
       expenditure justified by carbon alarmism. Ms Gillard will of course take no notice of
       these inconvenient truths.

    The governments, agencies, media, individuals and so on who have been promoting
    this AGW thing have invested too much credibility to ever voluntarily and gracefully
    re-examine their modeling with a scientific eye. They have to carry on now right over
    the cliff - the trick will be not letting them drag the rest of us with them.

    Brave scientists who are prepared to challenge the political LAW on climate change.
    Facts that do not comply with the political LAW are not admissible. These scientists
    will have all government funding cut off for whatever projects they wish to persue.
    They will be driven out of universities like coalition sympathizers driven out of the
    ABC. Money is only ever made available to those who consistently aim to prove the
    political LAW and ignore any findings to the contrary. The political LAW of climate
    change is L-A-W.

    According to Cape Grim measurement, since 1976 CO2 has increased by an average
    of 1.7 Parts Per Million per year. ....so CO2 has increased by around 60 Parts Per
    Million in the Earth's atmosphere since 1976. ....so "other" parts of the Earth's
    atmosphere have decreased by 60 Parts Per Million since 1976. ... and therefore
    999,940 Parts Per Million of the Earth's atmosphere have remained unchanged since
    1976. Can someone explain how the climate is changed by the movement of 60 ppm
    and static 999,940 ppm? I would suggest IPCC is having a lend of us. Y2K all over
    again?

    Unfortunately Bob, this Labor government has its hands over its ears with respect to
    climate change, and solely for political reasons. Having bribed the CSIRO and BOM
    with huge research grants, it intimidates them to stay "on message". No matter that
    even our once CSIRO's very own (Garth) Paltridge et al (2009) recently found
    negative feedbacks in historic radiosonde (weather balloon) data. Instead of positive
    feedback from assumed constant relative humidity, the clear, negative trends in the
    NCEP data implied that "long-term water vapor feedback is negative—that it would
    reduce rather than amplify the response of the climate system to external forcing such
    as that from increasing atmospheric CO2". This government also maintains the myth
    from one dodgy survey that 97% of scientists concur with the IPCC. The reality is that
    most scientists (and inquisitive laypeople) now accept that rising CO2 accounts for
    some of our very modest warming, along with human land-use change, increased
    black carbon, etc. and natural effects, but that the catastrophic forecasts are
    deliberately exaggerated. We badly need an election.

    All very fine, but the reason for the govt. to bring on a carbon tax, was to appease the
    Greens, not to save the planet. The carbon tax is for two different reasons, one as
    stated above, the other is to redistribute wealth. Even if the Greens now
    acknowledged that the climate is more stable than thought, the Govt. would still go
    ahead, it needs the money. We need to throw this govt. out before the damage is done,
    but that is proving not to be easy. I live on the land, the climate is very important to
    our livelihood, has it changed in the last twenty years? Well, NO. Australia will
    continue to go thru El Nina, El Nino, sometimes it is more obvious than other times,
    we simply need to build more dams, more than anything else, that should be our
    priority. The earth will continue to change and revolve as it always has, and anybody
    who thinks they can control it from Canberra are kidding themselves.

    this type of analysis which refers to the observational facts as opposed to the hype that
    to many uninformed governments and media outlets ignore; for example, the ABC
    and BBC. The tide has shifted against the alarmist and other rent seekers and they are
    in a panic. It's a great scene to behold. Their arrogance is finally giving way to despair
    and desperation. I constantly have debates with people regarding their belief system
    and not too many can even point to any empirical facts but simply rely on the IPCC
    models which have shown to be false. It is time to dismantle the IPCC and severely
    cut back on funding for what can only be described as a farce. Good on ya mate!

   lmwd of Qld Posted at 7:01 AM April 18, 2012

    This is exactly what people need to hear. The TRUTH! The public do NOT know that
    all the alarm was built on a scientific assumption (unproven guess). Incredibly, it
    turns out that the assumption was incorrect, going by the recent research of many
    different scientists in this field. This knowledge just hasn't filtered through into
    mainstream consciousness as yet. Our climate has negative feedbacks, not just
    positive as assumed, so can we cancel the crisis and do away with all the
    apocalypticism? Unfortunately the sunk costs with this theory are now to the tune of
    trillions of dollars worldwide. Scientific organisations, which jumped on this
    fashionable and lucrative bandwagon and based all their projections on this
    assumption, are in a corner financially and with their scientific credibility. They need
    the funding the Govt dishes out and in order for the Govt to keep dishing out the
    funding, the Govt needs the alarmism to scare people into paying more taxes. True
    believer zealots of dangerous manmade warming, science bodies and Govt in a
    corner, fight nasty. I expect to see the usual low personal attacks to smear the authors
    instead of engaging intelligently with the argument.

    attributed to long-term warming and cooling cycles throughout the Holocene, for
    which there is clear historical, archaeological and geological evidence

    Congratulations to the Australian for, once again, bringing the voice of moderation to
    the global warming/climate chane issue. This article can definitely NOT be
    characterised as a work of fanatical denialism or sociological deviance as some, like
    Prof Lewandowski at Uni of WA, would have us believe. It is simply a call for a
    review. What could be more moderate in its position than that? What could be more
    scientific in its approach and level- headed? I too have been fascinated in the past
    month at what appears to be a concerted onslaught of media releases and
    announcements about the impending doom. I have been fascinated by the fact that all
    this has been coming out, and yet many prominent scientists agree that any global
    warming trend is at a halt. They also agree CO2 levels are rising. The question is now,
    'Who are the (so-called and emotive word) 'denialists'? Are the sociological 'deviants'
    the people who refuse to go along with the 'herd' who believe the globe is continuing
    to warm? Or are the sociological deviants the people who refuse to take heed of the
    fact that at least some of the scientific observations do not match the warming models.
    We need a moratorium.

   Tony Downes of The Gap, Qld Posted at 7:49 AM April 18, 2012

    The teal crux of the articlemcomes in the the last line 'Unbiased review of the
    evidence'. With the current government lead by Julia Gillard an unbiased review of
    anything would be impossible. Every current review, think tank, or agency is stacked
    with hand picked labor party friendly appointees. If a review was mabel and the
    government didn't like it's findings it wouldn't see the light of day. In the end the
    evidence of little or no warming will win out and the barrow pushers of global
    warming will be proved wrong. Hopefully this will occur before we run out of money
    promoting useless carbon reduction schemes.

   Michael Cunningham of West End, Brisbane Posted at 8:03 AM April 18, 2012

    There are so many caveats and uncertainties about alleged catastrophic anthropogenic
    global warming that there are no grounds for taking strong action to reduce emissions.
    Actions to date have been very costly for no benefit. Temperatures have been flat for
    over ten years, we should scrap all anti-emissions measures until there is clearer
    evidence that (1) sustained long-term unusual temperature rises are actually occurring,
    (2) the costs of that rise exceed the benefits, (3) human emissions are the cause and
    (4) cutting CO2 emissions will actually have a significant impact on temperatures.
    None of these points have been proven.

    completely wedged on the carbon tax, and is obviously prepared to die in a ditch for
    it. Trouble is she is taking the country with her. Time for the Coalition to dump its
    "direct action" policy,and accept that nothing should be done until our trading
    partners have acted, and/or the whole AGW hypothesis is accepted as dead. Julias
    carbon tax meanwhile will be out in the economy like a "pacman" vacuuming up
    everything in its path courtesy of our energy dependence. Not a very positive outlook.
    Global Warmists need to accept that the horse is dead, and no ammount of flogging

    warming THEORY is all about protecting the rivers. Rivers of taxpayers money that
    will flow through the troughs of the various bodies mentioned above in Bobs article,
    with large chunks going overseas. Here's a quesiton for JuLiar, manmade global
    warming is true, why so many lies? Why lie about the carbon tax, why lie about
    carbon dioxide being pollution (it isn't), why the lie about the big polluters paying the
    tax, when the reason some of us receive partial compensation is because WE will
    ultimately pay the tax? We live in dangerous times, thankfully we have scientists like

    It is surprising that many tertiary-educated Australians with ready internet access to a
    range of official data, don't have an urge to get past the persuasion on both sides of
    the climate debate, to get to some official data on which they can form their own
    conclusions. Generally, they accept what they are being told by "the specialists".
    Anyone under 40 years of age, has been told continuously since primary school, that
    humans cause pollution, overuse and mis-use of resources, and global warming. They
    accept that as readily as we now accept that the Earth rotates around our sun. And of
    course they mix all these issues up, and see them all as having a common cause. One
    useful official source is the U.S. National Oceanic and Atmospheric Administration
    (NOAA). There are many interesting and relevant data series, such as on historical
    global temperatures, and sea levels for the latter,
    http://tidesandcurrents.noaa.gov/sltrends/sltrends.html . Look at some of these, then
    look at other sites of both sides of the argument, and make up your own mind. Just
    spend a few hours, that's all it takes, to provide better perspective to judge the
    arguments you read and hear.

    made global non-warming and CO2. True, the Coalition will repeal the carbon tax and
    wind back other Labor climate funding. But they still substantially support "the
    science" despite all the real world data that disproves the UN IPCC hypothesis upon
    which all this nonsense is based. I want an opposition to come out strongly, as Tony

    It is to the great credit of The Australian and to "real science" that articles such as the

    aware of the increasing prevalence of carefully orchestrated media disinformation
    campaigns on climate and many other topics. The presence of a clearly articulated

    Us sceptics strongly suspected all along that the climate funding grantees and

    continue their lemming like belief of the modelling. What is unforgivable is our
    "government" joining them without at least an honest look at swimming in the other
    direction. I have no doubt the learned authors of this article have done much more
    than write an opinion piece for the Australian to get the governments attention (and
    we all know the degree of difficulty associated with that). Perhaps publicizing the
    letters, the meetings, the conversations that have no doubt occurred (creating their
    own Climileaks campaign) may sway enough of the climate doolallys to get honest
    science back on the agenda? We can no longer shrug and say "what are we going to
    do" and let this government lead us to laughing stock status!

    But Bob, you don't seem to understand that the political left NEEDS everyone to
    believe that global warming exists. Without some overwhelming emergency like
    climate change there simply wouldn't be enough of an excuse for them to control our
    lives to the extent that they want to. Do you think the far left would be listened to by
    anyone if they tried to sell themselves as socialists or communists? Of course not!
    These days they get plenty of attention and support by pretending that our industrial
    wealth needs to be tightly controlled and diminished because of ENVIRONMENTAL
    concerns, and it's worked a treat for quite a while. It doesn't matter to them if global
    warming is actual reality or not. All that matters is that we all BELIEVE in it. We'll
    then be much more open to heavy regulation of most aspects of our lives. After all, it's
    an emergency, right? And we're to blame with our greedy consumption. Sacrifice will
    lead to redemption, for the end of the world is nigh, and all that stuff. Thankfully most
    of us are now on to them, and see through their transparent bid for power over us.
    And that's largely due to your efforts and courage, and of those like you. Thank you.

    Yes, yes, it's all obviously a conspiracy.... btw, what is this "strong contrary evidence"

    evidence that there definitely will NOT be dangerous global warming? As an
    "experienced scientist", you obviously know the difference between lack of
    compelling evidence in support of a theory as against "strong contrary evidence" that
    disproves the theory. You are implying you have the latter. So where is it?

    common sense statements etc. If it could not be proven it was discarded. Applying
    this technique to the global warming theory I have found and accept:- Fact 1. Carbon
    dioxide is a so called greenhouse gas. Fact 2. We have NO knowledge of the degree
    of global warming caused by the increased levels Carbon Dioxide. NONE! Fact 3.
    There is not one person or group of people who understand how our climate works.
    NO ONE!. Like Bob Carter I have spent many hours perusing various publications
    (such as the Critical Decade Report etc.) and find that they are filled with highly
    qualified statements and opinions that appear to me to be with out meaning. On what
    evidence, for example, would one base statements that talk about "Dangerous" global
    warming. Where would one get that knowledge? It is simply an opinion based on no
    evidence. I totally agree with the sentiments expressed in your article Bob. How can I
    help.

    Stand by for the vitriol that will be heaped upon these scientists, who appear to have
    no vested interest in pursuit of the facts

    But the "science is settled" and a carbon tax is the "roit thing to do"

    It would be good if this article could also appear in the "Herald" and the "Age". If
    necessary, a paid advertisement should be utilized.

    Such a review is extremely unlikely, at least by this government. Prime Minister Julia
    Gillard has invested the entirety of her political capital on the Carbon Tax. This term
    of this government would become a superfluous waste of time if it were to accept any
    scientific findings which contradicted the scientific rationalization of it's radical
    Carbon Tax agenda. The Labor Causcus are now joined at the hip to Julia Gillard so
    they must by necessity decry any factual evidence to the contrary. Labor and the
    Greens will if anything ramp up the propaganda machine to rationalize their existence
    and to save face. The political reality transcends actual reality, meaning that we are
    effectively led by people who are lost pretending to know the way.

    Oh Bob, you climate scaptic you, climate modelling are the true indicators of climate
    change and not measured data did you not know this, no one uses thermometers and
    wind gauges anymore to predict the cliamte, you should invest in a computer and a
    climate modelling software, these IT tools can do wounders with any sort of data,and
    the best thing is that you can do it it all in the comfort of your study, not need to
    venture out into nature, you should ask where the IPCC, CSIRO, BOM, Australain
    climate commission got their software from

    A 15 year temperature standstill despite increases in carbon pollution. Sceptics or as
    that Green Earthian and his new party leader Christine would say'The Deniers"have
    now every right to say'told you so". Computer modelling will produce answers that
    you require to support the argument. However as any computer nerd knows, garbage
    in equals garbage out. For this come 1 July we are being saddled with an unnecessary,
    unwanted and apparently unjustifiable carbon tax.This together with dodgy figures
    from Wayne Swan's Treasury are making Julia's government look even more
    irresponsible and inept

    David John Lloyd O'Halloran. Pigs might fly too John, but a paid ad. is a good idea.
    Perhaps one of the mining giants or giantesses might help out with the funds. The
    ABC is, of course a lost cause.

    To Paul of Brisbane (9.04 am today, 18th April). The facts are easy to find, and have
    been published in a range of forums. I had my doubts about global warming some
    years ago, and wondered if there was any at all. I decided to do my own research,
    looking at official data. There are two key types that we can reference easily - ocean
    and land surface temperatures since 1880, and sea level variations (some as far back
    as 120 years). I had to change my view - there is warming. It is at a very steady rate -
    about 0.9 degrees celsius (land and ocean surface measurements) over the last 100
    years. Sea level rises are also there - around 3 mm per annum on average, or about
    one foot per 100 years. Significantly, there has been no acceleration in temperature or
    sea level increases. Temperature has in fact levelled out over the last 10-15 years.
    These statements are based on official data. Meanwhile carbon dioxide levels are
    increasing significantly, I recall at something like 30% over the last ten years (need to
    verify this). You may care to read also my comment above posted at 8.44 am today.
    Happy, enjoyable and easy digging on the internet.

    My major issue with the climate change debate has always been rather hystirical
    utterings of the green movement scientists and their followers. This is the first article
    I've read that seems to lay out the facts. What it clearly shows is that the "debate" is
    politically rather than scientificaly motivated. Having said that I believe that countries
    should look at their pollution output to improve the quality of the air the population
    breathe. It would seem that the majority of countries that attended the Copenhagen
    conference got it right when they decided not to proceed with a global approach.

    Well done Dr. Carter et alia. I have never had any faith in the CAGW religion. Not a
    Geologist, nor a climate scientist. My face has been seen around the ABS however
    and I do know how to read a data set, and people who tamper with data are the very
    worst kind of people. Again, well done. Keep up the pressure in the name of sanity
    and scientific integrity.

    Samuel DiGiovanni of melbourne, I used to have the same attitude until the
    unintended consequences started to appear such as rent seekers like English organic
    farmers trying to limit access to their markets (based on food miles) for Kenyan
    organic farmers who are typically struggling women trying to support their family.
    My other concern (as a scientist) is what will become of the reputation of science in
    general. Another point, if the debate was serious more people would be willing to at
    least discuss the issue of nuclear power (especially thorium based). This has led me to
    believe that this is more about politics than science.

    So global temperatures and sea levels are rising at a steady rate over the last 100+
    years (with temperatures actually flattening over the last 10-15 years). There has been
    an acceleration in the amount of human-produced carbon dioxide over this period.
    Over the last twenty five years, climate models have been predicting much greater
    temperature and sea level rises, together with other effects on ice, ocean currents, and
    atmospheric disturbance. It is clear that the climate models are inadequate, and as yet
    cannot form a sound basis for prediction. Therefore, any policies based on those
    predictions have no substance. Indeed "the king has no clothes!" Because people find
    it hard to change their views, I've taken to drip-feeding little disturbing bits of
    information to those with whom I discuss climate change, to give them time to adjust,
    and to start questioning. It's interesting that of all the 44 comments so far on this
    article, I think only one expresses doubt about its claims. Has the tide started to turn at
    last?

         It is difficult to understand what has motivated politicians to adopt what has always
         been a siginficantly distorted debate. Al Gore still has audience with prime ministers
         despite clear evidence that all of his rhetoric is grossly exagerated. As far as the
         CSIRO and BOm are concerned one would have to question the timing. Budget
         settings are under discussion in Jan Feb and Mar, the budget is under pressure to find
         savings,ha, and the CO2 tax starts in July. There is a more coherent correlation here
         than CO2 and temperature.

         Everyone here seems to be ignoring the true threat - the planet is failing to adhere to
         our climate models. If the Earth continues to go off in its own direction and
         completely fail to pay any attention to what we tell it to do, who knows what can
         happen in the future. To rectify this stiuation, I suggest we implement a "preditcive
         modelling non-compliance tax" which will help to ensure that the Earth remains
         obedient for the sake of future generations.

         That this factual assessment of the AGW situation has appeared in a national
         newspaper is a tribute to the dedication and preference for ethical science of Bob
         Carter et al and ‘The Australian’. It should be available to every thinking
         Australian. We are indebted you.
