So he is not allowed to have any reasonable or sensible deduction that the current man-made global warming fairy-tale is a massive scam. Lets hope Hitler didn't believe two plus two equals four or else mathematics will have to be re-written.

The ice shelf has been a lot thinner and a lot less pervasive than it was, say, during the last ice age.

I'm not sure if you're being ironic or if you're genuinely unaware of what a swindle Comrade 'class warrior' (chuckle) Durkin's 'The Great Global Warming Swindle' piece is.

Misrepresenting and manipulative (that is, "lies" in everyday language), suffice to say it's the equivalent of no-planes 'science' - that is, it's devoid of any. And is no doubt equally attractive to the same demographic.

It's primary purpose was and obviously still is to float the idea that there is 'some doubt' about the cause of climate change; certainly more than enough to not interfere with the activities of Their Ownerships.
At least, that was the plan in directing all-important public opinion.

It's had several comprehensive new ones ripped in it since it was first shown a couple of years ago, but the following is fairly comprehensive while being light reading (sorry - I don't do vids).

"The film presented viewers with an apparently devastating refutation of the "theory of global warming". And these were not picky, esoteric criticisms. Durkin insisted that the world’s climate scientists are guilty of the most fundamental error imaginable: increased atmospheric carbon dioxide (CO2) is not the cause of higher temperature, as the experts claim. Quite the reverse: increasing atmospheric CO2 is itself the result of rising temperature.

As evidence for this contention, Durkin argued that global surface temperature dropped dramatically between 1945-1975, at a time when CO2 emissions were rapidly rising as a result of the postwar economic boom. According to Durkin, if CO2 emissions were responsible for increasing temperature, then temperature should not have fallen between 1945-1975. Clearly, then, some factor other than CO2 emissions must have caused the subsequent global temperature rise.

But Real Climate, an internet site run by climate scientists, such as NASA’s Dr Gavin Schmidt and Dr William Connelley of the British Antarctic Survey, describes Durkin’s discussion of the 1945-75 period as “deeply deceptive”. (Real Climate, March 9, 2007; www.realclimate.org/index.php/archives/2007/03/swindled)

In this section of the film, Durkin focused heavily on a graph depicting temperature changes. The graph, Real Climate comments, “looks rather odd and may have been carefully selected”. It appears to show a dramatic cooling between the 1940s and 1970s. But try flipping between the film’s version of the global temperature record (shown above left) and the temperature plot that normally appears in the scientific literature (shown above right) The supposed cooling looks rather less evident in this second graph.

Without knowing more details of how Durkin may have manipulated the data plotted in his graph, it is difficult to comment on the presentation. What we can say is that Durkin’s "four decades of cooling", implying a relentless temperature drop over 40 years, is not an accurate description of the trend over this period. There was some cooling for +part+ of this time but also some plateauing, with fluctuations up and down.

But why did the temperature not simply rise in line with the post-war increase in greenhouse gas emissions?

In fact, as is well-known, the absence of a global rise in temperature between 1945-75 is explained by the release of large amounts of industrial pollutants, called sulphate aerosols, into the atmosphere. These particles have a braking effect on global warming, known as “global dimming”. By shielding some of the incoming solar energy, sulphate aerosols mask the underlying warming effect generated by rising levels of CO2. By the 1980s, however, stronger warming had exceeded this masking effect and global temperature has since continued to rise. As Real Climate notes, by failing to explain the science behind this phenomenon the programme makers were guilty of “lying to us by omission.”

The Ice Cores
The film repeatedly gave the impression that mainstream science argues that CO2 is the sole driver of rising temperatures in the Earth's climate system. But this is not the case. Climate scientists are well aware that solar activity plays a role, though a minor one at present, as do long-term periodic changes in the Earth's orbit, known as Milankovitch cycles. (See: http://en.wikipedia.org/ wiki/Milankovitch_cycles)

The point is that there is a vast body of evidence that very strongly supports the hypothesis that greenhouse gas emissions, of which CO2 is the most important, are primarily responsible for recent global warming. The 4th and most recent scientific assessment of the Intergovernmental Panel on Climate Change (IPCC) concludes:

"Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely [.i.e. probability greater than 90%] due to the observed increase in anthropogenic greenhouse gas concentrations." ('Climate Change 2007: The Physical Science Basis,' Summary for Policymakers, IPCC, February 2007, page 10; www.ipcc.ch/SPM2feb07.pdf)

We then come to one of the film's most misleading arguments. Antarctic ice cores show that rises in levels of CO2 have lagged 800 years behind temperature rises at specific times in the geological past. This, argued Durkin, +proves+ that CO2 cannot be responsible for global warming - instead global warming is responsible for increasing levels of CO2. But this was a huge howler.

What Durkin's film failed to explain was that the 800-year lag happened at the end of ice ages which occur about every 100,000 years. (See: www.realclimate.org/index.php/ archives/2004/12/co2-in-ice-cores)

Scientists believe that the end of an ice age is likely triggered when the amount of heat reaching the Earth rises as a result of a periodic change in the Earth's orbit around the sun. Jeff Severinghaus, Professor of Geosciences at Scripps Institution of Oceanography, explains why the rise in CO2 initially lags behind the temperature rise:

"The reason has to do with the fact that the warmings take about 5000 years to be complete. The lag is only 800 years. All that the lag shows is that CO2 did not cause the first 800 years of warming, out of the 5000 year trend." (Real Climate, 'What does the lag of CO2 behind temperature in ice cores tell us about global warming?’, December 3, 2005; www.realclimate.org/index.php /archives/2004/12/co2-in-ice-cores/)

The best current explanation for the lag of 800 years is that this is how long it takes for CO2, absorbed by the ocean in an earlier warm period, to be "flushed out" at the end of an ice age. Once that CO2 has been released into the atmosphere its heat-trapping properties as a greenhouse gas lead to even stronger warming: an example of positive feedback. (See Caillon et al., 'Timing of Atmospheric CO2 and Antarctic Temperature Changes Across Termination III,' Science, 14 March 2003: Vol. 299. no. 5613, pp. 1728 - 1731)

Professor Severinghaus summarises:

"In other words, CO2 does not initiate the warmings, but acts as an amplifier once they are underway."

Durkin’s analysis, then, was way off the mark.

The film’s claim that solar activity might account for recent warming is also without credibility. In September 2006, the Times reported the latest findings from researchers writing in the top journal, Nature:

“Scientists have examined various proxies of solar energy output over the past 1,000 years and have found no evidence that they are correlated with today's rising temperatures. Satellite observations over the past 30 years have also turned up nothing. ‘The solar contribution to warming... is negligible,’ the researchers wrote in the journal Nature.” (Anjana Ahuja, ‘It's hot, but don't blame the Sun,’ The Times, September 25, 2006)

The film's other scientific claims can be similarly dismissed. Carl Wunsch - who, as discussed, appeared in the film - comments:

“What we now have is an out-and-out propaganda piece, in which there is not even a gesture toward balance or explanation of why many of the extended inferences drawn in the film are not widely accepted by the scientific community. There are so many examples, it's hard to know where to begin, so I will cite only one: a speaker asserts, as is true, that carbon dioxide is only a small fraction of the atmospheric mass. The viewer is left to infer that means it couldn't really matter. But even a beginning meteorology student could tell you that the relative masses of gases are irrelevant to their effects on radiative balance. A director not intending to produce pure propaganda would have tried to eliminate that piece of disinformation.” (http://ocean.mit.edu/~cwunsch/ papersonline/channel4response)

“I Was Duped” - Déjà Vu?
Many readers will be aware that Durkin has previous ‘form’. In 1997, Channel 4 broadcast his three-part series, Against Nature, which suggested present-day environmentalists were the true heirs of the Nazis. (See George Monbiot, ‘The Revolution Has Been Televised,’ The Guardian, December 18, 1997; www.monbiot.com/archives/1997/ 12/18/the-revolution-has-been-televised/)

Several interviewees who appeared in the film felt they had been misled about the programme-maker’s agenda. Responding to complaints, the Independent Television Commission (ITC) found that the editing of interviews with four contributors had "distorted or misrepresented their known views". (Geoffrey Lean, ‘Climate change: An inconvenient truth... for C4,’ The Independent, March 11, 2007; http://news.independent.co.uk/ environment/climate_change/article2347526.ece)

In addition, the ITC found: "The interviewees had also been misled as to the content and purpose of the programmes when they agreed to take part." (Paul McCann, ‘Channel 4 told to apologise to Greens,’ The Independent, April 2, 1998)

Ten years on, it appears that history may have repeated itself. In his letter of complaint to the film-makers cited above, Carl Wunsch writes:

“I have some experience in dealing with TV and print reporters and do understand something of the ways in which one can be misquoted, quoted out of context, or otherwise misinterpreted. Some of that is inevitable in the press of time or space or in discussions of complicated issues. Never before, however, have I had an experience like this one. My appearance in the ‘Global Warming Swindle’ is deeply embarrassing, and my professional reputation has been damaged. I was duped---an uncomfortable position in which to be.

“At a minimum, I ask that the film should never be seen again publicly with my participation included. Channel 4 surely owes an apology to its viewers, and perhaps WAGTV owes something to Channel 4. I will be taking advice as to whether I should proceed to make some more formal protest.” (http://ocean.mit.edu/~cwunsch/ papersonline/channel4response)

Eight of the scientists in the film - John Christy, Paul Reiter, Richard Lindzen, Paul Driessen, Roy Spencer, Patrick Michaels, Fred Singer and Tim Ball - are linked to American neo-conservative and right-wing think-tanks, many of which have received tens of millions of dollars from Exxon.

Greenpeace provides a fascinating online ’map’ detailing how Exxon funds these climate sceptics. Go to: http://www.exxonsecrets.org/ index.php?mapid=831 (click ‘Launch’ then click ‘skip intro’)

In his book, Green Backlash, environmental journalist Andrew Rowell noted that Fred Singer has also attacked scientific and environmental stances on other green issues such as ozone, acid rain, automobile emissions and even whaling. Singer has worked for companies such as Exxon, Shell, Arco, Unocal and Sun.

According to the Environmental Research Foundation, a non-governmental organisation:

“For years, Singer was a professor at the University of Virginia where he was funded by energy companies to pump out glossy pamphlets pooh-poohing climate change.” (Quoted, Sharon Beder, Global Spin, Green Books, 1997, p.94)

Rowell wrote that a quarter of Patrick Michaels’ research funding was reportedly received from companies such as Edison Electric Institute, the largest utility trade association in America. Michaels’ magazine, World Climate Review, was funded by the Western Fuel Association and a video produced by him was funded by coal companies and distributed by the Denver Coal Club. (Rowell, Green Backlash, Routledge, 1996, p.143)

Both Singer and Michaels represented the fossil fuel lobby’s Global Climate Coalition and the Competitive Enterprise Institute, a leader in global warming scepticism.

Journalist Ross Gelbspan noted that in May 1995, Richard Lindzen and Patrick Michaels were hired as expert witnesses to testify on behalf of Western Fuels Association, a $400 million consortium of coal suppliers and coal-fired utilities. Gelbspan said of Lindzen:

“I don't know very many supporters of Mr Lindzen who are not in the pay of the fossil fuel lobby. Dr Lindzen himself, his research is publicly funded, but Dr Lindzen makes, as he told me, $2,500 a day consulting with fossil fuel interests, and that includes his consulting with OPEC, his consulting with the Australian coal industry, his consulting with the US coal industry and so forth. That's not to say Dr Lindzen doesn't believe what he says, but it is to say that he stands in very sharp distinction to really just about virtually all of the climate scientists around the world.” (Tony Jones, ‘Journalist puts global warming sceptics under the spotlight,’ Australian Broadcasting Corporation, March 7, 2005; www.abc.net.au/lateline/ content/2005/s1318067.htm)

Journalist George Monbiot wrote of Philip Stott:

“Professor Stott is a retired biogeographer. Like almost all the prominent sceptics he has never published a peer-reviewed paper on climate change. But he has made himself available to dismiss climatologists' peer-reviewed work as the ‘lies’ of ecofundamentalists.” (Monbiot, ‘Beware the fossil fools,’ The Guardian, April 27, 2004; http://environment.guardian.co.uk/ climatechange/story/0,,1829315,00.html)

Paul Driessen is a fellow at two right-wing think tanks in the US, which are part of the Wise Use movement. One of the think tanks is headed by Ron Arnold, who has spent the last twenty years attacking the environmental movement. His fellow director is a fundraiser for America's gun lobby. The list goes on...

By contrast, Greenpeace spokeswoman Mhairi Dunlop said her organisation had been interviewed by Durkin but none of the material had been included in the film:

"They interviewed us but I guess what we said didn't fit in with the [story] they were peddling." (McCandless, op. cit)

Following the film’s broadcast, Professor Martin Rees, president of the Royal Society - the government-sponsored academy of sciences for the United Kingdom - has said that many factors contribute to global warming but it is clear that emissions of "greenhouse gases," particularly CO2, are to blame for most of the current temperature rise. Rees added:

"Those who promote fringe scientific views but ignore the weight of evidence are playing a dangerous game. They run the risk of diverting attention from what we can do to ensure the world's population has the best possible future." (Ibid)

On March 11 the Observer published a letter from a group of climate scientists responding to Durkin’s film:

“This programme misrepresented the state of scientific knowledge on global warming, claiming climate scientists are presenting lies. This is an outrageous statement...

“We defend the right of people to be sceptical, but for C4 to imply that the thousands of scientists and published peer-reviewed papers, summarised in the recent international science assessment, are misguided or lying lacks scientific credibility and simply beggars belief.” (Alan Thorpe, Natural Environment Research Council, Brian Hoskins, University of Reading, Jo Haigh, Imperial College London, Myles Allen, University of Oxford, Peter Cox, University of Exeter, Colin Prentice, QUEST Programme, letter to the Observer, Sunday March 11, 2007;
http://observer.guardian.co.uk/ letters/story/0,,2031117,00.html)

Viewed from one perspective, Channel 4 has done a huge public disservice in spreading absurd and mendacious arguments guaranteed to generate confusion. This at a time when a fragile momentum is building on the need to take urgent action on the very real threat of catastrophic climate change.

But from another perspective it may well be that this film does for climate scepticism what Tony Blair’s “dodgy dossiers” did for the pro-war movement ahead of the invasion of Iraq. Wildly distorted propaganda often does have a powerful initial impact. But stretched beyond a certain point of unreality, it also has a tendency to turn on, and bite, the propagandists.

Durkin’s grandiose prediction that his film “will go down in history” will surely prove correct, although perhaps not for the reasons he imagined."

No irony there chek, disagreement is constructive.

Both camps seem to have ammo, and a consensus hasn't been reached.

That's all fine, and we should all learn to disagree politely.

There are quite a few gaps in the argumentation against the GWS film, mostly around the causality issue.

What is particularly damning for the climate change agenda for many people is the way it has been embraced by the media and some establishment mouthpieces (e.g. Al Gore et al).

Of course the current model is non-sustainable.

A control tactic used again and again:

The best way to control the outcome of a debate is to control both sides of the debate: thesis vs. antithesis -> synthesis.
