Entertaining, informative Lord Monckton — peerless

This event is over. It was a great success, with as many turned away as were admitted.

the northern club

The Climate Realists network, most ably and energetically led by our good friends Esther and Neil Henderson, have managed the coup of this deepening southern winter by prevailing upon Christopher Monckton to extend his tour Downunder and visit New Zealand when he’s finished stirring up our Aussie cousins. Well done, the Hendersons! Brave of you, m’Lord! Now come on, you lot, hurry up so you don’t miss out!

An occasion with Lord Monckton not to be missed

Global climate change is seen by many as the world’s biggest threat. But is it real, or are we subject to some kind of monstrous “group think”? How has the science behind climate change been formulated and communicated? Is the science reliable? Do the policies now being enacted at (our) great expense stand any chance of stopping the warming? What does the future hold?

Viscount Monckton of Brenchley

Leading climate change skeptic Viscount Christopher Monckton — hereditary British peer, journalist, businessman and entertaining public speaker – says:

  • Global temperature change is well within natural variation
  • The so-called spate of extreme weather is a myth: there were more cyclones in the 1800s than there are today
  • Consensus (of the Intergovernmental Panel on Climate Change (IPCC) scientists) does not make climate change true
  • If you choose your time-frame carefully you can make any trend look as if it is increasing or decreasing
  • Al Gore’s movie An Inconvenient Truth is riddled with inconvenient errors

Lord Monckton will explain why carbon dioxide is beneficial to the Earth and mankind, that it is not a pollutant, that emissions of it, mainly natural, cannot and will not change natural rises and falls in global temperature which have occurred throughout history.

Any attempts by humans to “control” the temperature of the Earth cannot succeed, and the imposition of charges such as our ETS tax cause pain without any possible gain. After his address, Lord Monckton will welcome questions from the audience.

Lord Monckton is a most entertaining speaker — whichever side of the global warming debate you support.

    O/T but Ken Perrot appears to be claiming that this is a right-wing hate site that is tacitly supporting the mass murder in Norway by not explicitly condemning it.

    I guess it’s best to ignore comments like this,

    Here and in the US and the UK the support he gets are from people who already think the same way. Don’t forget his manifesto is basically a cut and past of hate mongering easily found on the internet. It is the sort of stuff previously presented here by people like Treadgold and local conservative Chrsitians and that you yourself are advancing.

    but you can add your tuppence if you want. I’ve got drawn into it but wish I hadn’t

    • Thanks, Andy. Once someone is finally talking to Perrott he never lets them go, they have to tear themselves away. He makes outrageous statements to get people to talk to him because he’s incapable of having an ordinary conversation or asking how you’re getting on. He’s a lightweight and I won’t waste my energy on him. There’s no rational connection between climate scepticism, religious fundamentalism, world government and mass murder, and it’s stupid to suggest one. Perrott is a cretin.

      Ken’s only chance of expanding his readership beyond his 4 regular website visitors is to try to draw people to his site by spouting complete rubbish (in much the same way as I mentioned the NZ Herald does). My advice is not to fall into his trap, he’ll never admit he’s wrong anyway regardless of how obvious it is so it’s a waste of time. Perrott’s just an attention junkie who wants his readership to rise from 4 to 5. Ignore him, he’ll fade into obscurity where he belongs.

    Word has it (via Ken Shock on Facebook) that the Greens have pulled out of the Auckland debate

    “There has been a change of plan for us in relation to Dr Graham’s debate
    with Lord Monckton.

    Earlier today the TV show Q&A approached us about our Co-leader Dr Russel
    Norman debating Lord Monckton on that show this Sunday morning. Dr Norman is
    unable to do the show as he is out of the country, but the invitation
    sparked a conversation within our leadership about would he have appeared
    anyway. We made the decision that he would not have, and for that reason Dr
    Graham has decided it is no longer appropriate for him to debate Lord
    Monckton if our leadership wouldn’t.

    I want to stress that Dr Graham accepted your offer to debate in good faith,
    and continued to be happy to debate right up until our party position on the
    matter changed.
    On reflection we do not think it is appropriate for our party leader to
    debate with Lord Monckton on the science of climate change as that sends a
    message that there is uncertainty regarding the existence and causes of
    climate change. Our participation in a TV debate on this matter sends a
    message to viewers that the science is uncertain, and that is a position
    that we do not wish to convey. Science has processes to determine accuracy
    (to the best of our knowledge at any given time). We feel that Lord Monckton
    sits outside of these processes and outside the scientific consensus on
    climate change. It is notable that leading scientists around the world
    refuse to debate the fact of human induced climate change with Lord Monckton
    on that basis. We side with these leading scientists and the scientific
    consensus.

    As a political party our interest is in how we address the realities of
    climate change. That climate change is real is the near consensus view of
    parties in parliament too, hence the National Party supporting an ETS. The
    ETS is based on the assumption we need to reduce CO2 in the atmosphere.
    Finding ways to create a sustainable future is our priority, not
    re-litigating the accepted science.

    So because we will not debate Lord Monckton on television is it the
    consistent position for Dr Graham to also withdraw from the event next
    Thursday also. I apologise that this position was not reached sooner, and
    appreciate that some materials or notices may have been distributed that are
    now inaccurate. Please accept our apologies for this.

      I’m more than willing to debate Chris Monckton. He can come down to Dunedin or pay my way to any other venue in NZ before August 10. I guarantee a better workout than like-minded Geoff Austin will provide.

      Mike,
      Maybe you can tag-team with Geoff Austin at PRINZ on Thursday 4th?
      I don’t suppose Monckton’s itinerary will extend to The Mainland, unfortunately.
      I am in Auckland on that night so hope to get along and meet the rest of the “cranks”. How will we recognise each other?. Do we all have facial ticks or wear strange masonic lodge regalia?
      Maybe a secret handshake, or a paper clip attached to the buttonhole (the emblem of the Norwegian resistance during WW2)?

    Re the politically accepted “scientific consensus” in Andy’s Green Party v Monckton comment.

    I’ve just had a response from MftE CC in regard to my 18 page case that 7 key climate metrics are not performing as per AGW this century. The case was referenced to at least 20 peer-reviewed papers (many post 2007) and hot-linked to most of them.

    The case for each metric was accompanied by a challenge repeated from the initial contact e.g.

    “The challenge remains for MfE CC to compile an observed GAT dataset for this century overlaid with prerequisite levels to validate AGW/IPCC projections and to publish it on the CC website.”

    Here’s the response (complete with scanned doc conversion typos and the misspelling of my name – a recent development):-
    —————————————————————————————————————————
    Dear Mr Cummings
    Thank you for your emails of 29 June and 4 July 2011 regarding climate metrics.

    The Ministry for the Environment does not publish data on the climate trends as this information is widely available from other sources and is updated on an appropriate timescale. Our primary source is the |PCC’s assessment reports, in which peer reviewed data and science is presented with due consideration for its policy relevance. This information is availabie to anyone, and is updated around once in every seven years — an appropriate timescale when considering data and trends that will be of concern over the next hundred years.

    in the analysis you have sent, you seem to be focussing only on the short term data, i.e., looking at the last five or the last 10 years. This is not an appropriate timescale with which to be considering climate change. For example, in your quoting from the Solomon (2010) paper you comment on the last period of ‘little change‘ ignoring the previous two and a half decades of increases. Short term periods with little change or even decreases in climate parameters are likely to be expected from natural variability. For example, after analysis of surface temperature records and climate model data, Easterting and Wehner (2009)‘ state: “Claims that global warming is not occurring that are derived from a cooling obsenred over such short time periods ignore this natural variability and are misleading”. Trends in climate parameters over periods longer than a decade still show that the climate is changing in a way that is entirely consistent with the theory of anthropogenic global warming.

    In making my statement that the information ‘is consistent‘ with climate change I have accepted that there will be short term variability and have hence considered the longer timescales. I continue to stand by my statement that the observed climate metrics are consistent with what we would expect from anthropogenic climate change.

    In formulating policy on climate change we use peer reviewed science as our evidence base. Much of what you present here comes from the climate change science web site which is neither invigilated or peer reviewed. Many of the ‘issues’ raised there have been dealt with in peer reviewed literature.
    Yours sincerely

    A magnificent fob-off from an AGW-contrary-science-blind propaganda outlet stuck in an IPCC AR4 2007 mind-time warp I think you will all agree.

    That the recent radical change in OHC is just short-term (less than a decade in this case) natural variability and of no consequence to climate change is hogwash, she obviously knows nothing about thermal inertial lag and probably subscribes to the “atmosphere heats the ocean” school of thought.

    Ocean heat store makes climate change inevitable

    17 March 2005 by Bob Holmes – NewScientist

    No matter how well the world controls emissions of greenhouse gases, global climate change is inevitable, warn two new studies which take into account the oceans’ slow response to warming.

    Even if greenhouse gases never rise beyond their present level, temperatures and sea levels will continue rising for another century or more because of a time lag in the oceans’ response to atmospheric temperatures, say researchers.

    This time lag means policymakers cannot afford to wait to tackle climate change until its consequences become painful, because by then they will already be committed to further change, they urge. “The feeling is that if things are getting bad, you hit the stop button. But even if you do, the climate continues to change,” says Gerald Meehl, a climatologist at the US National Center for Atmospheric Research (NCAR) in Boulder, Colorado.

    Meehl and his colleagues used two sophisticated computer models of global climate to predict what would happen under various scenarios for greenhouse gas emission controls, taking into account the oceanic time lag. Their most optimistic scenario – in which atmospheric concentrations of greenhouse gases are capped at year 2000 levels – would require severe cuts in CO2 emissions, far beyond those set in the Kyoto protocol.

    But even this optimistic scenario predicts that global temperatures would continue to rise by between 0.4°C and 0.6°C over the next century. That increase is comparable to the increase in global temperature during the 20th century of about 0.6°C. A second, independent study using a simpler climate model by Tom Wigley, another climatologist at NCAR, paints the same bleak picture.

    Thermal inertia

    The time lag occurs because rising air temperatures take time to make themselves felt throughout the immense thermal mass of the oceans. This “thermal inertia” means that Earth has not yet felt the full effect of today’s level of greenhouse gases, explains Meehl.

    And because water expands as it warms, this time lag in temperature will continue to push sea level higher. Meehl’s models predict that thermal expansion alone would make sea levels rise by about 11 centimetres over the next century, even if greenhouse gases were held at 2000 levels.

    The real rise would almost certainly be more, he says, because his models do not include the effect of melting of glaciers and icecaps, which will be more rapid in a warmer world.

    In fact, the climatic time lag may be pushing Earth closer to a catastrophic glacial melting, scientists warn. James Hansen, a climatologist at NASA’s Goddard Institute for Space Studies in New York, US, has estimated that global temperature may need to rise just 1°C more to tip the balance toward abrupt melting. “That’s why the warming already ‘in the pipeline’ is important,” he says. “It takes us closer to the slippery slope.”

    “We have got climate change in store no matter what,” agrees Andrew Weaver, a climatologist at the University of Victoria, Canada. “We have to be prepared to assist those who cannot adapt.”

    And,

    “………a time lag in the oceans’ response to atmospheric temperatures, say researchers.”

    Whaaaaaaaat??????

    We are dealing with freaking nutcases that have all the physics concepts and thermodynamic processes a**** about face. The peak in ocean warming that we have seen this century is the result of solar heating last century (the thermal inertial lag). The lag is over, there’s no more warming unless the sun gets busy again and the atmospheric temperatures have nothing to do with it.

    I haven’t got back to MftE CC yet – I have to wait for my own thermal lag to subside first.

    • Bob D on 28/07/2011 at 2:09 pm said:

      So, apart from their obvious gaffe, how do they explain the fact that in spite of this inevitable, unstoppable inertia pressing forward regardless of future emissions cuts, the oceans are cooling? Whoops.

    • Richard C (NZ) on 28/07/2011 at 4:47 pm said:

      “how do they explain”? – natural variability seems to be the answer.

      I haven’t been pushing an “ocean is cooling” or “planet is cooling” meme with MftE CC, I went with “If the ocean is not warming, there’s no global warming – period.”

      On reflection, I’m encouraged by Dr Power’s response because it helps set the respective positions for ongoing debate and opens up new angles of attack (among other things) on their “long-term” only rationale.

      First, for example, Dr Power cites Easterling and Wehner (2009) “ls the climate warming or cooling?”, that gets prominence at blogs like SkepticalScience (no doubt Power is a loyal fan). Paper linked here:-

      http://www.esrl.noaa.gov/psd/csi/images/GRL2009_ClimateWarming.pdf

      It looks at observed linear trends (simplistically) and modeled trends (why I don’t know – includes Meehl et al. 2007).

      Now I’m not denying that there’s been an underlying trend of global warming over the last 300 years as perhaps Power thinks I do, I’m just questioning the attribution of significant anthropogenic influence. So where in that 300 year series is there evidence (apparent or proven) of an anthropogenically forced acceleration? And if its there, why has natural variability overridden it as Easterling and Wehner implicitly concede?

      This ties in nicely with the new Loehle and Scafetta paper “Climate Change Attribution Using Empirical Decomposition of Historical Time Series”

      http://wattsupwiththat.com/2011/07/25/loehle-and-scafetta-calculate-0-66%C2%B0ccentury-for-agw/

      They calculate 0.66°C/century for AGW and the paper obviously has its roots in Scafetta’s “Empirical Evidence for a Celestial Origen of the Climate Oscillations and its Implications” paper. Their residual linear trend 1950 – 2010 (Fig 2 WUWT post) indicates anthropogenic acceleration starting at 1950 but remember that I plotted the underlying HadCRUT3 quadratic from “Celestial Origens” against LD-ML CO2 and found that temperature LEADS CO2 which I pointed out to MftE CC and they’ve studiously ignored. The temperature acceleration starts about 1870 and the CO2 acceleration starts around 1945 i.e. CO2 lags temperature in the 20th century.

      E&W say:-

      “Here we analyze both the observed record and a series of climate model simulations for the occurrence of both positive and negative decadal trends in the globally averaged surface air temperature to show that it is possible, and indeed likely to have a period of as long as a decade or two with no trend in an anthropogenically forced climate.”

      From L&S (assuming the anthro attribution) and E&W, I posit that the climate is both naturally and anthropogenically forced and over the last decade natural forcing has overridden anthro forcing and probably will do to at least 2030 (excluding quiet sun consideration). Dr Power states:-

      “In making my statement that the information ‘is consistent‘ with climate change I have accepted that there will be short term variability and have hence considered the longer timescales.”

      1) Does she concede the possibility of “no trend in an anthropogenically forced climate” due to “short term variability” that may last 30 years (which defines “climate”) rather than the 20 years that E&W state if it is to follow the trends of “longer timescales” that L&S show?

      2) How does she reconcile the inconsistency of CO2 lagging the underlying trend of temperature (1870 vs 1945) in her “longer timescales” with her assertion that “the observed climate metrics are consistent with what we would expect from anthropogenic climate change”?

      Secondly, I will press for the MftE CC understanding of how the ocean is warmed e.g.

      3) Do they subscribe to the notion as per the NewScientist article that the atmosphere and GHGs heat the ocean and if so to please describe the process in physics terms with reference to peer-reviewed science (and please refer to my Hale and Querry reference previously provided that proves the physical impossibility of it and has been cited 1470 times).

      4) If yes to 3), a) do they subscribe to the notion that ocean warming will resume soon as a result of rising AGHG emissions so that anthropogenic forcing overrides natural variability? b) If yes, why hasn’t that happened since 2003/04? c) Or can anthropogenic forcing only happen when natural variability is in abeyance?

      5) If no to 3), what would contribute to resumed ocean warming if rising AGHG emissions (and therefore anthropogenic forcing) will not?

      Stuff like that.

  7. Alistair on 28/07/2011 at 8:54 pm said:

    Came across this site via a UK Daily telegraph blog so I thought I’d leave a few thoughts.

    Because of major scientific errors, no climate model can predict climate. In 2004, NASA physicist Ferenc Miskolczi left because they refused him permission to publish his discovery that ‘back radiation’ in the 1922 paper by English Astronomer Sir Arthur Milne was a mathematical mistake; last year I realised the prediction by Carl Sagan of cooling by polluted clouds supposed to hide high feedback CO2-AGW assumes a single optical process when there are two. NASA knew this by 2004 and commissioned work to find out why.

    In 2004, NASA [ http://geo.arc.nasa.gov/sgg/singh/winners4.html ] substituted for Twomey’s correct physics, a ‘surface reflection’ idea which apparently reconciled the new observations with theory. There’s no such physics. It was a con. to deceive from authority the rest of oxymoronic ‘climate science’ and it worked. The only ‘evidence’ for high feedback in AR4, ‘cloud albedo effect’ cooling, Figure 2.4, doesn’t exist but climate science accepted it..

    Yes, that’s right, AR4’s conclusions are fraudulent. Extend the logic and Miskolczi showed a water planet’s atmosphere self controls about constant greenhouse warming [well less than half the claimed 33K because they convolve in it lapse rate], also the real AGW we had in the late 20th Century was probably from aerosol pollution,, as Asia industrialised, increasing light transmission through clouds. Because it’s particularly marked at short wavelengths needed to warm deep seas, this explains palaeo-climate.

    The latter is fascinating: Hansen was convinced of CO2-GW by palaeo-climate and set out to prove it by modelling. However, recent results show the fast heating of the ocean which restarted deep currents was at the edge of the Antarctic ice cap 1300 years before air temperature rose and 2100 years before [CO2] rose. [Warm water to 4°C and it sinks.]

    So, there is no CO2-GW or AGW. The World is cooling fast. as we enter a new Maunder Minimum of solar activity. The UK Met/. Office shows the key signs of changes in official mindset, having moved its head of modelling and officially assuming 50% solar, 50% CO2-AGW as it tries to regain credibility. I suspect this claim is to massage Cameron and his eco-fascist wif’e’s egos that CO2-GW is still in the Hadley model, but in reality I suspect they’re working overdrive to recalibrate for reality, hence they had to shift the boss.

    I wonder if he was a Marxist entryist, perhaps like the guy who fiddled NZ’s very important.temperatures? Interestingly, Marxist Jim Hansen is keeping high the feedback CO2-AGW idea alive by claiming aerosol cooling is double what he had thought. Pat Michaels has commented that experiment disproves this because the Northern hemisphere has warmed recently more than the South, which is what you’d expect if Chinese aerosols acted in the way I describe, and it’s observed experimentally.

    So, 35 years’ ago, Hansen made an honest mistake. Come 2004 and NASA lied to get AR4. The mistake has been identified and the weather organisations are quietly backtracking. The Marxist entryists are getting desperate and the backing down of your guy vs Monckton [a bit of a prat but sound] is yet another symbol of retreat.

    • Bob D on 29/07/2011 at 9:19 am said:

      Hi Alistair,

      Interesting thoughts, but I confess I’m confused by one point. You point out the Twomey effect as:

      The basic premise was simple and a wonderful example of Professor Twomey’s incisive thought: if pollution contributes additional nuclei upon which water can condense, then the condensed mass of water will consist of a larger concentration of smaller drops. The reflectance of the cloud will increase because the total surface area of the condensed water in cloud is greater when spread over more droplets. Although pollution alone may directly affect climate by modifying the absorption and scattering properties of the cloud-free atmosphere, the effect of pollution on clouds is potentially even larger; cloud droplets interact with radiation much more strongly than the nuclei upon which they form because they are typically several orders of magnitude greater in size.

      So reflectance increases with increased aerosol pollution, and seems to make sense. But then you imply this is incorrect physics (or do you?), by saying:

      [NASA] substituted for Twomey’s correct physics, a ‘surface reflection’ idea which apparently reconciled the new observations with theory. There’s no such physics. It was a con.

      What then was the correct original Twomey idea, and how is it different to NASA’s?
      I note you disagree with aerosol-cloud reflectance because you say later:

      …the real AGW we had in the late 20th Century was probably from aerosol pollution,, as Asia industrialised, increasing light transmission through clouds.

      and again:
