Lord Monckton wins global warming debate at Oxford Union

I’m waiting for actual photos of the event from the official photographer, but for now I’ll make do with what can be found on the Internet. For those who don’t know, the Oxford Union is the top of the food chain for scholarly debate. This is a significant win.

Founded in 1823 at the University of Oxford, but maintaining a separate charter from the University, The Oxford Union is host to some of the most skillful debates in the world. Many eminent scholars and personalities have come and either debated or delivered speeches in the chamber. Monckton was invited as part of the formal Thursday debate.

It is described as follows:

The Union is the world’s most prestigious debating society, with an unparalleled reputation for bringing international guests and speakers to Oxford. It has been established for 182 years, aiming to promote debate and discussion not just in Oxford University, but across the globe.

Here is a view inside from a previous debate:

Oxford Union Debate on Climate Catastrophe

Source:  SPPI

Army of Light and Truth 135, Forces of Darkness 110

For what is believed to be the first time ever in England, an audience of university undergraduates has decisively rejected the notion that “global warming” is or could become a global crisis. The only previous defeat for climate extremism among an undergraduate audience was at St. Andrew’s University, Scotland, in the spring of 2009, when the climate extremists were defeated by three votes.

Last week, members of the historic Oxford Union Society, the world’s premier debating society, carried the motion “That this House would put economic growth before combating climate change” by 135 votes to 110. The debate was sponsored by the Science and Public Policy Institute, Washington DC.

Serious observers are interpreting this shock result as a sign that students are now impatiently rejecting the relentless extremist propaganda taught under the guise of compulsory environmental-studies classes in British schools, confirming opinion-poll findings that the voters are no longer frightened by “global warming” scare stories, if they ever were.

When the Union’s president, Laura Winwood, announced the result in the Victorian-Gothich Gladstone Room, three peers cheered with the undergraduates, and one peer drowned his sorrows in beer.

Lord Lawson of Blaby, Margaret Thatcher’s former finance minister, opened the case for the proposition by saying that the economic proposals put forward by the UN’s climate panel and its supporters did not add up. It would be better to wait and see whether the scientists had gotten it right. It was not sensible to make expensive spending commitments, particularly at a time of great economic hardship, when the effectiveness of the spending was gravely in doubt and when it might do more harm than good.

At one point, Lord Lawson was interrupted by a US student, who demanded to know what was his connection with the Science and Public Policy Institute, and what were the Institute’s sources of funding. Lord Lawson was cheered when he said he neither knew nor cared who funded the Institute.

Ms. Zara McGlone, Secretary of the Oxford Union, opposed the motion, saying that greenhouse gases had an effect [they do, but it is very small]; that the precautionary principle required immediate action, just in case and regardless of expense [but one must also bear in mind the cost of the precautions themselves, which can and often do easily exceed the cost of inaction]; that Bangladesh was sinking beneath the waves [a recent study by Prof. Niklas Moerner shows that sea level in Bangladesh has actually fallen]; that the majority of scientists believed “global warming” was a problem [she offered no evidence for this]; and that “irreversible natural destruction” would occur if we did nothing [but she did not offer any evidence].

Mr. James Delingpole, a blogger for the leading British conservative national newspaper The Daily Telegraph, seconded the proposition, saying that – politically speaking – the climate extremists had long since lost the argument. The general public simply did not buy the scare stories any more. The endless tales of Biblical disasters peddled by the alarmist faction were an unwelcome and now fortunately failed recrudescence of dull, gray Puritanism. Instead of hand-wringing and bed-wetting, we should celebrate the considerable achievements of the human race and start having fun.

Lord Whitty, a Labor peer from the trades union movement and, until recently, Labor’s Environment Minister in the Upper House, said that the world’s oil supplies were rapidly running out [in fact, record new finds have been made in the past five years]; that we needed to change our definition of economic growth to take into account the value lost when we damaged the environment [it is artificial accounting of this kind that has left Britain as bankrupt as Greece after 13 years of Labor government]; that green jobs created by governments would help to end unemployment [but Milton Friedman won his Nobel Prize for economics by demonstrating that every artificial job created at taxpayers’ expense destroys two real jobs in the wealth-producing private sector]; that humans were the cause of most of the past century’s warming [there is no evidence for that: the case is built on speculation by programmers of computer models]; that temperature today was at its highest in at least 40 million years [in fact, it was higher than today by at least 12.5 F° for most of the past 550 million years]; and that 95% of scientists believed our influence on the climate was catastrophic [no one has asked them].

Lord Monckton repeatedly interrupted Lord Whitty to ask him to give a reference in the scientific literature for his suggestion that 95% of scientists believed our influence on the climate was catastrophic. Lord Whitty was unable to provide the source for his figure, but said that everyone knew it was true. Under further pressure from Lord Monckton, Lord Whitty conceded that the figure should perhaps be 92%. Lord Monckton asked: “And your reference is?” Lord Whitty was unable to reply. Hon. Members began to join in, jeering “Your reference? Your reference?” Lord Whitty sat down looking baffled.

Lord Leach of Fairford, whom Margaret Thatcher appointed a Life Peer for his educational work, spoke third for the proposition. He said that we no longer knew whether or not there had been much “global warming” over the 20th century, because the Climategate emails had exposed the terrestrial temperature records as defective. In any event, he said, throwing good money after bad on various alternative-energy boondoggles was unlikely to prove profitable in the long term and would ultimately do harm.

Mr. Rajesh Makwana, executive director of “Share The World’s Resources”, speaking third for the opposition, said that climate change was manmade [but he did not produce any evidence for that assertion]; that CO2 emissions were growing at 3% a year [but it is concentrations, not emissions, that may in theory affect climate, and concentrations are rising at a harmless 0.5% a year]; that the UN’s climate panel had forecast a 7 F° “global warming” for the 21st century [it’s gotten off to a bad start, with a cooling of 0.2 F° so far]; and that the consequences of “global warming” would be dire [yet, in the audience, sat Mr. Klaus-Martin Schulte, whose landmark paper of 2008 had established that not one of 539 scientific papers on “global climate change” provided any evidence whatsoever that “global warming” would be catastrophic].

Lord Monckton, a former science advisor to Margaret Thatcher during her years as Prime Minister of the UK, concluded the case for the proposition. He drew immediate laughter and cheers when he described himself as “Christopher Walter, Third Viscount Monckton of Brenchley, scholar, philanthropist, wit, man about town, and former chairman of the Wines and Spirits Committee of this honourable Society”. At that point his cummerbund came undone. He held it up to the audience and said, “If I asked this House how long this cummerbund is, you might telephone around all the manufacturers and ask them how many cummerbunds they made, and how long each type of cummerbund was, and put the data into a computer model run by a zitty teenager eating too many doughnuts, and the computer would make an expensive guess. Or you could take a tape-measure and” – glaring at the opposition across the despatch-box – “measure it!” [cheers].

Lord Monckton said that real-world measurements, as opposed to models, showed that the warming effect of CO2 was a tiny fraction of the estimates peddled by the UN’s climate panel. He said that he would take his lead from Lord Lawson, however, in concentrating on the economics rather than the science. He glared at the opposition again and demanded whether, since they had declared themselves to be so worried about “global warming”, they would care to tell him – to two places of decimals and one standard deviation – the UN’s central estimate of the “global warming” that might result from a doubling of atmospheric CO2 concentration. The opposition were unable to reply. Lord Monckton told them the answer was 3.26 plus or minus 0.69 Kelvin or Celsius degrees. An Hon. Member interrupted: “And your reference is?” Lord Monckton replied: “IPCC, 2007, chapter 10, box 10.2.” [cheers]. He concluded that shutting down the entire global economy for a whole year, with all the death, destruction, disaster, disease and distress that that would cause, would forestall just 4.7 ln(390/388) = 0.024 Kelvin or Celsius degrees of “global warming”, so that total economic shutdown for 41 years would prevent just 1 K of warming. Adaptation as and if necessary would be orders of magnitude cheaper and more cost-effective.

Mr. Mike Mason, founder and managing director of “Climate Care”, concluded for the opposition. He said that the proposition were peculiar people, and that Lord Monckton was more peculiar than most, in that he was not a real Lord. Lord Monckton, on a point of order, told Mr. Mason that the proposition had avoided personalities and that if Mr. Mason were unable to argue other than ad hominem he should “get out”. [cheers] Mr. Mason then said that we had to prepare for climate risks [yes, in both directions, towards cooler as well as warmer]; and that there was a “scientific consensus” [but he offered no evidence for the existence of any such consensus, still less for the notion that science is done by consensus].

The President thanked the speakers and expressed the Society’s gratitude to the Science and Public Policy Institute for sponsoring the debate. Hon. Members filed out of the Debating Chamber, built to resemble the interior of the House of Commons, and passed either side of the brass division-pole at the main door – Ayes to the right 135, Noes to the left 110. Motion carried.

Mike quotes the the 100% political appointees writing propaganda for the IPCC:

Current global temperatures are warmer than they have ever been during at least the past five centuries, probably even for more than a millennium. If warming continues unabated, the resulting climate change within this century would be extremely unusual in geological terms. Another unusual aspect of recent climate change is its cause: past climate changes were natural in origin (see FAQ 6.1), whereas most of the warming of the past 50 years is attributable to human activities.

Let’s deconstruct:
First, provide testable, empirical evidence showing that the warming of the past 50 years is due to human activity.
And if global temps are warmer than for the past 500 years, then nothing unusual is happening, because it’s all happened before pre-SUV. It’s called natural variability. And the MWP was also warmer than now, as was the Minoan Optimum.
There is also ample evidence that the Earth’s temperature as measured at the equator has remained within +/- 1°C over the past billion years. And equatorial temperatures have not changed over the past 50 years. [source]
But as one approaches the poles, the Earth’s temperature naturally begins to vary more and more from one area to another, and from summer to winter, and from one pole to another. The higher one gets in latitude, the bigger the temperature swings. 
That’s why the current variability in the Arctic is nothing unusual. It is normal, and it has repeatedly happened.  Greenland has very wide temperature swings, as is shown in the Greenland ice core samples, while Egypt is extremely uniform from year to year, from century to century, and from millennium to millennium. Egypt’s temperature is the same today as it was when Ptolemy and Cleopatra ruled.
When the equator starts warming beyond its normal, narrow range, wake me. Until then, what we’re seeing is simply natural climate variability… unless CO2 is steering clear of the equator. That’s always possible, I suppose.

It’s ridiculous that Al Gore is preaching consumers on how to make changes in their lives to reduce global warming, but he does very little to backup his crusade.
He uses a private jet to promote his film, him and his wife Tipper live in 2 houses: a 20 room mansion, eight-bathroom in Nashville, a 4,000 square-foot in Arlington, VA and a 3rd home in Carthage, Tenn.
With that alone he uses more energy than 95% of the American public. For someone encouraging personal sacrifice, he demands very little from himself.

Funny how conversations go astray. In commenting on “whether humans changed the climate”, which is one of those “have you stopped beating your wife questions”; I offered that Heisenberg implied thatmerely by being an observer we change what we are observing:-
“”” And as for human effects; well Heisenberg tells us that simply trying to observe the state; results in changing that state; so what else is new. The more important issue is whether it is possible for the earth temperature system to go into runaway heating that leads to a hot Venus State. “””
So first off, Jbar jumps on that with this:-
“”” Jbar says:
May 26, 2010 at 3:13 am
George E. Smith –
Criminy! Heisenberg’s Uncertainty Principle applies only to atom-sized and sub-atomic particles. It is too small of a phenomenon to apply to macroscopic objects, let alone climatic systems. It does not create any barrier to measuring global temperature. “””
and this:-
“”” Jbar says:
May 26, 2010 at 6:31 pm
George E. Smith –
Roughly speaking, Heisenberg’s Uncertainty Principle is that you cannot precisely measure both the momentum and the position of a particle because the energy of the photon that you use to make the measurement affects the result.
The larger the mass of particle you hit with a photon to measure it, the smaller the relative or percent uncertainty in the measurement.
For macroscopic particles, the percent uncertainty is vanishingly small, essentially zero.
Well of course that is not true; Heisenberg’s principle applies to everything; including the speed trap situation I mentioned later. If you have a very short trap; so you know the car location quite well, the errors in your timing will make the velocity (and momentum) less accurate; and if you lengthen the trap to reduce the effect of timing errors; you know less about where the car was when it had the calculated speed. That is exactly the message of Heisenberg. What he did beyond that was show that there is a fundamental limit to how small you can make the product delta position x delta momentum which must be greater than h/2pi; h being Planck’s constant.
And that limit most certainly applies to an automobile speed trap; well unless someone wants to claim that in the case of the speed trap it is possible to reduce the error product below h/2pi; anybody want to take that position.
These measurment situations are fractal; and no matter the scale of the system there tends to be a relationship between the size of the system, and the amount of disturbance one must make in trying to observe it.
Certainly at the microscopic size of the small particle world; indeed the photon energy used to observe the particle will change the momentum by some un-knowable amount. And that momentum change does NOT depend on the mass of the particle; that is part of the source of the momentum. yes the velocity change will depend on the mass of the particle; but not the momentum.
One look at all the termoil that goes along with climatologers trying to observe the temperature of the earth;shoul indicate to anyone; that they themselves are altering their surroujndings in that endeavour; evn if it is just the Catlin nutcakes boring holes in the ice to measure its thickness; that will accelerate the melting; as will running an ice breaker through there so idiots can kayak in the arctic.
So what about this:- “”” runaway heating that leads to a hot Venus State. “””
Mike interprets that as a question asking for information about the Planet Venus; which he ‘attempted to supply’.
I never said a word about the planet Venus ; simply mentioned “a hot Venus state”. I could have said a “hot pressure cooker state” and evidently Mike would have offered information about pressure cookers.
yes later I did offer that CO2 has a 4.0 micron absorption band that we simply cannot reach via CO2 on planet earth; but it does operate on the Planet Venus; nowhere did I then ask for information on the Planet Venus; the conditions there; and what happens there have no relevence to the climate of earth. Of course the public media do keep trundling out that situation as a future earth environment; and of course the AGW crowd of scientists do nothing to dissuade them from thinking that is even remotely possible; well the way Hansen raves; you would think that is just around the corner.
But I’m quite happy to let anyone believe that Heisenberg’s principle has a cutooff size beyond which it doesn’t apply; that’s why I asked jbar what size that is; because as far as I know there is no system of any size where the product of the uncertainties in position and momentum (simultaneously) ever can be less that h/2pi; so as far as I am concerned it applies to everything from quarks to galaxies.

George E. Smith
May 27, 2010 4:37 pm

Well both of the heavy duty PhD Physicists in my Department; including my boss; say unequivocally that Heisenberg’s Uncertainty Principle applies to anything and everything no matter the size. Of course we are all in agreement that for most macro scale things the Heisenberg limit of h/2pi is way down in the noise; but all macro systems exhibit the same problem that certain parameters can only be measured with higher precision; at the expense of some other parameter.
The principle has practical everyday application in certain types of LEDs where light emission is generally of very low quantum efficiency; because they are indirect band gap semi-conductors. Materials such as Gallium Phosphide are indirect; whereas Gallium Arsenide is a direct gap semi-conductor; so efficient, (but Infra-red) LEDs can be made in GaAs; as well as alloys of the GaAl As system.
The GaASP alloy system is direct for low fractions of Phosphorous (45% P. Unfortunately you need greater than that for yellow LEDS and for pure GaP you have both an indirect gap and you still don’t get a real green (grellow instead)
For the non- experts, a direct gap semiconductor has the minimum energy gap occur at the same momentum value so a simple photon emission can occur to emit light. For indirect gap materials the minimum energy gap occurs with different momenum values; so you need to get both a photon and a phonon involved in the reaction to conserve energy and momentum; and that is a much lower probability occurrence. The Phonon of course just heats the crystal.
So to get around this problem; these indirect materials can be doped with so-called iso-electronic trap impurities; such as Nitrogen or a complex like Zn-O in pure GaP.
So Nitrogen substitutes in the lattice for Phosphorous; in effect creating a highly localised sample of Gallium Nitride; which has a somewhat larger band gap than GaP or GaAsP.
The N atoms form specific sites where an electron or hole can be captured. Since the location of the capture is now pegged within atomic dimensions; then per Heisenberg’s principle the momentum of the electron becomes more uncertain; so the electron “orbitals” I suppose you would call them, spread out in momentum space; so that the electron may now be found under the band gap minimum; and so make a direct transition to the valence band with the emission of a photon. This process results in high efficiency amber or yellow light emission from what was previously a low probability recombination process.
In pure GaP, the Zn-O complex performs the same function and yieds higher efficiency grellow light. Some of these things are now obsolete since the GaN and GaInN; or GaAlInN alloys are much wider band gaps, and mostly direct band gap materials to make green, blue Violet, and UV LEDs.
So Heisenberg really does manifest itself in everyday mundane things like LEDs; although that is still an atomic scale phenomenon.

Smokey: Every fact stated by Viscount Monckton has been thoroughly discussed right here and repeatedly verified.”
Testimonial evidence, Smokey?
“But after hearing the facts, they came to the proper conclusion: that Lord Monckton was right…”
To come to that conclusion they would have needed independent verification of Monckton’s “facts”.

Brendan H
May 28, 2010 12:27 am

Zane: “Clearly, and definetively, Monckton, had the facts…”
It’s the facts that are in contention. Claiming that Monckton won the debate because he possessed the “facts” begs the question in two ways. First, it assumes he did in fact possess the facts; secondly, it assumes his listeners knew enough about climate to verify his facts.
Neither of these assumptions can be established merely by pointing to the outcome of the debate.
Debates are an opportunity for people to present various viewpoints and for others to hear those viewpoints, so in that sense they have value. But debate per se cannot establish the facts, which are established by observation, experiment etc.

May 28, 2010 3:48 am

Brendan H,
That is so lame. All you have to do is show that any of the facts in the article are wrong. Or man up, and admit that Monckton won fair and square.
Instead, we get rhetoric, complaints and excuses.

“http://stats.org/stories/2008/global_warming_survey_apr23_08.html
Scientists agree that humans cause global warming
Ninety-seven percent of the climate scientists surveyed believe “global average temperatures have increased” during the past century.”
Mike, this is what is called in the trade a “selection effect” in that, if you want a predetermined result in your survey, you select who takes the survey so that you get the effects you desire.
It also suffers from the false proposition fallacy. Assuming that the contrary view is that no warming is caused by humans at all is false. Most everyone agrees that humanity has some contribution to climate change. The debate is over how much humans are responsible for. Those of us on the skeptical side of things tend to expect that at least half of warming of recent years is due to solar influences. Most of the other half is statistical noise and natural cycles like PDO, ENSO, NAO, etc. .. Any significant “human cause” is more likely caused by errors in the temperature record caused by poor surface station siting, as well as faulty statistical methods and other mathematical manipulations and massages that make the results completely useless for anything but selling a fraudulent proposition to gullible politicians and other useful idiots.

From the SPPI coverage, “Lord Monckton, a former science advisor to Margaret Thatcher during her years as Prime Minister of the UK”.
Monckton was never a science advisor to Margaret Thatcher. He worked in No 10 as an adviser on education policy.
Just a small point.

Crumb,
You have put a lot of hard work into your presentation and still I am saddened by the lack of ability to distinguish between ‘models’ and actual science. You, in your presentation, continually misrepresent Monckton’s claims or say that he is misquoting a scientist. Simply because an author presents data does not necessitate that the conclusion about the data will be the same as anothers interpretation of the data. Nor does the data all interrelate to the conclusion. Thus far in your presentation all I see are scientists saying “antrhopegenic” global warming is occuring but none of them are providing any facts. Rather, their own findings on various issues are being tauted as evidence for man-made global warming when in fact their evidence is derived from the IPCC findings or ‘models’ dealing with future predictions.
I was eager to see something of significance in your presentation but seeing your quotes and emails from the scientists you contacted simply strengthens Monckton’s arguments and once again solidifies the arguments against anthropogenic global warming.
A note to all. Please watch this presentation and make sure to read the whole emails being quoted and also make sure to listen to Moncktons speech that he is referencing with the slides from Monckton. Once you do you will have a much better picture of how Monckton is shown to be more logical.
The issue is ‘model’ vs ‘science’. Many of the people making claims about antrhopogenic global warming base it off of ‘models’ not science.

I might add the following about the famous 1933 (not 1935) ”This House would in no circumstances fight for its King and country” debate.
The proposer of the motion, Kenelm H. Digby said afterwards: “I believe that the motion was representative neither of the majority of the undergraduates of Oxford nor of the youth of this country. I am certain if war broke out tomorrow the students of the university would flock to the recruiting office as their fathers and uncles did.”. And so it proved: when World War Two broke out six-and-a-half years later, a recruiting board was organised at Oxford which invited undergraduates and resident postgraduates under 25 to enlist: nearly 90% of a possible 3,000 volunteered.
Mr Watts, you really shouldn’t get over-excited about this, and your statement that “For those who don’t know, the Oxford Union is the top of the food chain for scholarly debate. This is a significant win.” is frankly a bit silly.
Oxford Union debates have always been more about debating skills – and fun – than about the search for truth; and when the students do discuss something serious, they (a) like to enjoy themselves, and (b) they rather take pride in causing the occasional national furore, both by who they invite (violence-proposing Malcolm X, banned leading IRA man Gerry Adams, post-acquittal OJ Simpson), and by their decisions – as happened in no uncertain measure after the 1933 debate.
But a lot of the time it is just fun – among other past speakers at the Union have been Ron Jeremy the porn star, Michael Jackson (who spoke on child welfare), a Sun Newspaper page 3 girl (that’s a bare-breasted model for American readers)…and, um, Kermit the Frog.
I should listen to the thousands of boring old grown-up scientists in the field, not a small group of clever kids having a good time.

Entertaining article, and I am encouraged by the result, but one thing caught my eye: “CO2 is rising by a harmless 0.5% per year”, or words to that effect. 20 years of such an increase would lead to levels 10% higher than today. I think that’s unlikely to be harmful, but it’s not valid to pretend that such a change is just noise in the signal. If you have a basis for stating that’s harmless, then fine, trot it out. Otherwise, you’re making an argument by assertion, which is exactly what the Goracles do all the time. Best to avoid their tactics.
Remember that the effect of CO2 on temperature is logarithmic. A doubling (sans any forcing) will increase temperatures about one or two degrees (sorry, I can’t remember and I’m too lazy to look it up). Therefore a 10% increase (one tenth of a doubling) will have an insignificant impact.

Monckton quoted the recipe in the debate, 4.7 ln(390/388). It is a temperature rise of 4.7 C for a 2.718 times increase in concentration.
