I write to report on a debate that defeated the motion “This House Believes Global Warming is a Global Crisis” during a meeting of the St Andrews University Debating Society. It is difficult to arrange a debate of anthropogenic (that is, man-made) global warming (AGW) because few proponents of AGW are willing to face such debate. They know from past experience that they always lose such debates because there is no evidence that AGW exists and much evidence that it does not.

However, on Wednesday 4 March 2009, the St Andrews University Debating Society held their debate of the motion, “This House Believes Global Warming is a Global Crisis” in the Old Parliament Building, St Andrews. The debate was organized and presided over with exemplary efficiency and professionalism by the Speaker of the Society, Ms Jessica Siegel. It was conducted with all the pomp and ceremony that could be expected of an ancient society of so ancient and prestigious a university.

Updated below by Richard Courtney And the debate was lively, informative and entertaining. It got emotional at times. Some of the contributions from the floor were of exceptionally high quality. But, it was somewhat spoiled by the weakness of the proponents of the motion. (I have good reason to suspect this weakness is because stronger speakers could not be obtained to propose the motion. If so, then it is yet another example of leading proponents of AGW fearing to face their critics in open debate).

The proponents of the motion were Ross Finnie MSP, former Scottish Government Minister for Environment and Rural Development; Mike Robinson, Chief Executive of the Royal Scottish Geographical Society and Chair of Stop Climate Chaos Scotland; Gregory Norminton, Novelist ‘Serious Things’, Environmental Activist, Founder of ‘Alliance against Urban 4x4s’

The motion was opposed by myself, and Nils-Axel Morner, Leader of the Maldives International Sea-Level Project who was awarded the ‘Golden Contrite of Merits’ by Algarve University, Viscount Monckton of Brenchley, Former advisor to then UK Prime Minister Margaret Thatcher and now an Investigator of Scientific Frauds.

Each speaker was given a strict maximum of 7 minutes to speak. The speakers would alternate between proponents and opponents of the motion until all 6 had spoken. No speaker was allowed to speak more than once except to raise a point of information, order, or etc.

The proponents had clearly not prepared. They were not co-ordinated in their presentations, they each lacked any significant knowledge of the science of AGW, and they each assumed that AGW is a fact. None of them made a substantial presentati on of arguments supporting the motion, and they all (including the politician!) lacked adequate skills at public speaking. The opponents of the motion were a sharp contrast to that. They each have significant expertise in their subject, and they had agreed the case they were to put and how they were to put it. Also, they are all very competent public speakers and their very different styles made their presentation much better than the sum of its parts.

Finnie spoke first. He argued that AGW is a fact because the United Nations (UN) Intergovernmental Panel on Climate Change (IPCC) has published its Fourth Assessment Report (AR4) that says the IPCC is “90% certain” that AGW exists. From this he claimed there is a “crisis” because governments are failing to give the matter sufficient importance. It is necessary for governments to de cide a treaty that would follow-on from the Kyoto Ptotocol that intends to constrain emissions of greenhouse gases (GHGs) but ends in 2012. The decision needs to be made at a meeting later this year.

I replied by outlining the case for the opposition. My speech is copied here. It asserts that governments do need to have policies on climate change but empirical evidence denies the existence of AGW and so there is no need to constrain fossil fuel emissions. Indeed, the harm caused by the emission constraints would be greater than any harm that AGW could induce if it were to exist.

Robinson’s response was very angry. He seemed to think attacking the opposition speakers would provide a victory for the motion. Almost his entire speech was attempted defamation of the opposition speakers. Within seconds of starting to speak he had accused them of being “like supporters of the Nazis in 1930s Germany” (my family lost everything in the blitz so I did not take kindly to that). The speakers on the opposition side “could not get anything published in peer-reviewed journals” (Morner and I each shouted out that we have and we do). And much of the same. He said people and governments must act to stop global warming (but he did not say how they should act) because - according to him - if a person had an elevated temperature of 2 degrees then he would die so we cannot let the Earth get 2 degrees hotter in case that kills the Earth.

Morner then gave a witty, entertaining and informative lecture on sea level change. The major potential threat from AGW is severe sea-level change. He interacted with the audience and selected one individual to ja pe with (his skill at this selection was later demonstrated when that individual stood and gave a speech that won the prize - of a Society neck-tie - for best speech from the floor). Morner presented data that showed sea level is not rising as a result of AGW at a detectable rate anywhere.

Norminton then spoke to conclude the case for the proponents of the motion. Like Finnie he seemed to be extremely nervous: both were shaking during their presentations. Norminton’s hand was shaking so much he put it into his pocket. (I know others interpret this to be nervousness, but I think it was extreme anger: Norminton had not expected any opposition to the motion, and the assertion of clear evidence that AGW does not exist was - to him - an outrage too hard to accept.) Also, like Finnie, he did not address the motion. He said he was not a scientist so he had to accept the word of scientists about global warming and scientists agree that gl obal warming is real and man-made. He said, the speakers on the opposition side were “not scientists”. Lord Monckton interjected that “Courtney and Morner are”. And Norminton replied, “So was Mengele.” Monckton raised a Point of Order demanding withdrawal of the remark. Norminton lacked the wit to withdraw and move on, so he refused to withdraw. Monckton persisted pressing the Point of Order and Norminton continued to refuse to withdraw. Only moments before Morner had made himself the lecturer the students would most like to have, and support for Norminton drained away as he insisted that Morner was akin to a murderer operating in a Nazi concentration camp. Norminton continued by saying the threat of global warming was real, and it was killing polar bears, but it is not clear that anybody was listening to him.

Monckton then summated the case for the opposition. He had not prepared a speech but took notes of the proponents’ speeches with a view to refuting arguments of the proponents that Morner and myself had not covered, and by defending the opposition case against rebuttals of its arguments. This was a deliberate use by our side of Monckton’s debating skills. But he had a problem because the proponents of the motion had not made a case and they had not addressed any of our arguments. Instead, they had made personal attacks on the opposition speakers, and they had asserted - with no evidence or argument - that the IPCC is right. So, Monckton’s summarizing speech consisted of evidence that the proponents of the motion had merely provided errors of logic and fact but they had not a case. He pointed out that polar bears had quadrupled their number in recent decades and this was not a sign that their species is threatened. And he cited and named each of the logical fallacies utilized by the proponents of the motion.

The debate then opened to the floor. Four persons each spoke well. One gave a balanced pr esentation and the other three spoke in favour of the motion. But by then the debate had been settled. Prior to the debate the opponents of the motion had expected to lose the vote because the students have been exposed to a lifetime (i.e. their short lifetime) of pro-AGW propaganda. We consoled ourselves with the certainty that we would win the arguments because opponents of AGW have all the facts on our side. But in the event we won both. The motion was defeated when put to the vote.

However, this result deserves some explanation.

The Members of the debating Society know the Rules of the House say a motion falls (i.e. is not carried) unless the motion obtains a majority of the votes cast. And the Speaker and Secretary of the Society say the Members use this knowledge to vote tactically: people who want a motion defeated but do not want it said they voted against the motion can - and do - register a vote that acts against the motion by abstaining.

On Wednesday the votes cast were
For the motion 57
Against for the motion 42
Abstaining 18

Thus the motion fell bec ause the 57 votes for the motion were less than the total of other votes cast (i.e. 42 against + 18 abstaining = 60 not for the motion).

Additionally, the room holds 197 people and there were very few empty seats, so there must have been at least 180 people present. Assuming an attendance of 180, then 63 people chose not to vote. So, it seems that fewer people were willing to support either side in the debate than were not willing to support either side.

After the debate several people said they changed their view from support of the motion as a result of the debate. It would have been interesting to know how those present would have voted prior to the debate.

Speech opposing the motion

Madam Speaker, Friends:

Climate change is a serious problem. All governments need to address it.

In the Bronze Age Joseph (with the Technicolour Dreamcoat) told Pharaoh that climate has always changed everywhere: it always will. He told Pharaoh to prepare for bad times when in good times, and all sensible governments have adopted that policy throughout the millennia since.

It’s a sensible policy because people merely complain at taxes in good times. They revolt if short of food in bad times. But several governments have abandoned it and, instead, are trying to stabilise the climate of the entire Earth by controlling it.

This attempt at global climate control arises from the hypothesis of anthropogenic (that is, man-made) global warming (AGW).

AGW does not pose a global crisis but the policy does, because it threatens constraint of fossil fuels and that constraint would kill millions – probably billions – of people.

There’s no evidence for man-made global warming; none, not any of any kind.

The existence of global warming is not evidence of anthropogenic global warming because warming of the Earth doesn’t prove human’s warmed it. At issue is whether humans are or are not affecting changes to the Earth’s temperature that have always happened naturally.

The AGW-hypothesis says increased greenhouse gases – notably carbon dioxide – in the air raise global temperature, and anthropogenic emissions of carbon dioxide are increasing the carbon dioxide in the air to overwhelm the natural climate system.

But empirical evidence says the hypothesis is wrong.

1. The anthropogenic emissions and global temperature do not correlate.

2. Change to atmospheric carbon dioxide concentration follows change to global temperature at all time scales.

3. Recent rise in global temperature has not been induced by rise in atmospheric carbon dioxide concentrations.
Global temperature fell from 1940 to 1970, rose to 1 998, and has fallen since. That’s 40 years of cooling and 28 years of warming. Global temperature is now similar to that of 1990. But atmospheric carbon dioxide concentration has increased at a near constant rate and by more than 30% since 1940. It has increased by 8% since 1990.

4. Rise in global temperature has not been induced by anthropogenic emissions of carbon dioxide.
Over 80% of the emissions have been since 1940 and the emissions have been increasing at a compound rate. But since 1940 there have been 40 years of cooling with only 28 years of warming. There’s been no significant warming since 1995, and global temperature has fallen since the high it had 10 years ago.

5. The pattern of atmospheric warming predicted by the AGW hypothesis is absent.
The hypothesis predicts most warming of the air at altitude in the tropics. Measurements from weather balloons and from satellites both show cooling at altitude in the tropics.

So, the normal rules of science say the AGW-hypothesis is completely refuted.
Nothing the hypothesis predicts is observed, and the opposite of some of its predictions are observed.

But some people promote the hypothesis. They’ve several reasons (personal financial gain, protection of their career histories and futures, political opportunism, and…). But support of science cannot be one such motive because science denies the hypothesis. So, additional scientific information cannot displace the AGW-hypothesis and cannot silence its advocates. And those advocates are not scientists despite some of them claiming they are.

Advocates promote AGW using three kinds of pseudo-science.

They use ‘argument from ignorance’. This isn’t new. In the Middle Ages experts said, “We don’t know what causes crops to fail: it must be witches: we must eliminate them.” Now, experts say, “We don’t know what causes global climate change: it must be emissions from human activity: we must eliminate them.” Of course, they phrase it differently saying they can’t match historical climate change with known climate mechanisms unless an anthropogenic effect is included. But evidence for this “anthropogenic effect” is no more than the evidence for witches.

Advocates rely on not-validated computer models.
No model’s predictions should be trusted unless the model has demonstrated forecasting skill. But climate models have not existed for 20, 50 or 100 years, so they cannot have demonstrated forecasting skill.

Simply, the climate models’ predictions of the future have the same demonstrated reliability as the casting of chicken bones to predict the future.

Advocates use the Precutionary Principle saying we should stop greenhouse gas emissions in case the AGW hypothesis is right. But that turns the Principle on its head.

Stopping the emissions would reduce fossil fuel usage with resulting economic damage. This would be worse than the ‘oil crisis’ of the 1970s because the reduction would be greater, would be permanent, and energy use has increased since then. The economic disruption would be world-wide. Major effects would be in the developed world because it has the largest economies. Worst effects would be on the world’s poorest peoples: people near starvation are starved by it.

The precautionary principle says we should not accept the risks of certain economic disruption in attempt to control the world’s climate on the basis of assumptions that have no supporting evidence and merely because they’ve been described using computer games.

So, global warming is not a global crisis but the unfounded fear of global warming is. It threatens a constraint of fossil fuel use that would kill millions – probably billions – of people.

Thankyou.

Richard
