35 Inconvenient Truths: The Errors In Al Gore's Movie

The following article expands on a British Judge's conclusion that Al Gore's film, "An Inconvenient Truth" contains at least 9 major factual errors, and is obvioulsy politically motivated, and thus should only be shown in UK schools with a disclaimer. Basically, the Judge is saying Al Gore's movie is just political opinion, not scientific fact, and it should be viewed as any other piece of political propaganda. I'm going to post each of the 35 "Inconvenient Truths", so each can be examined on its own merit. Read on and let's hear what you think.

35 Inconvenient Truths
The errors in Al Gore’s movie
A spokesman for Al Gore has issued a questionable response to the news that in October 2007 the High Court in London had identified nine “errors” in his movie An Inconvenient Truth. The judge had stated that, if the UK Government had not agreed to send to every secondary school in England a corrected guidance note making clear the mainstream scientific position on these nine “errors”, he would have made a finding that the Government’s distribution of the film and the first draft of the guidance note earlier in 2007 to all English secondary schools had been an unlawful contravention of an Act of Parliament prohibiting the political indoctrination of children.

Al Gore’s spokesman and “environment advisor,” Ms. Kalee Kreider, begins by saying that the film presented “thousands and thousands of facts.” It did not: just 2,000 “facts” in 93 minutes would have been one fact every three seconds. The film contained only a few dozen points, most of which will be seen to have been substantially inaccurate. The judge concentrated only on nine points which even the UK Government, to which Gore is a climate-change advisor, had to admit did not represent mainstream scientific opinion. Ms. Kreider then states, incorrectly, that the judge himself had never used the term “errors.” In fact, the judge used the term “errors,” in inverted commas, throughout his judgment.

Next, Ms. Kreider makes some unjustifiable ad hominem attacks on Mr. Stewart Dimmock, the lorry driver, school governor and father of two school-age children who was the plaintiff in the case. This memorandum, however, will eschew any ad hominem response, and will concentrate exclusively on the 35 scientific inaccuracies and exaggerations in Gore’s movie.Ms. Kreider then says, “The process of creating a 90-minute documentary from the original peer-reviewed science for an audience of moviegoers in the U.S. and around the world is complex.” However, the single web-page entitled “The Science” on the movie’s official website contains only two references to articles in the peer-reviewed scientific journals. There is also a reference to a document of the IPCC, but its documents are not independently peer-reviewed in the usual understanding of the term.Ms. Kreider then says, “The judge stated clearly that he was not attempting to perform an analysis of the scientific questions in his ruling.” He did not need to.

Each of the nine “errors” which he identified had been admitted by the UK Government to be inconsistent with the mainstream of scientific opinion.Ms. Kreider says the IPCC’s results are sometimes “conservative,” and continues: “Vice President Gore tried to convey in good faith those threats that he views as the most serious.” Readers of the long list of errors described in this memorandum will decide for themselves whether Mr. Gore was acting in good faith. However, in this connection it is significant that each of the 35 errors listed below misstates the conclusions of the scientific literature or states that there is a threat where there is none or exaggerates the threat where there may be one. All of the errors point in one direction – towards undue alarmism. Not one of the errors falls in the direction of underestimating the degree of concern in the scientific community. The likelihood that all 35 of the errors listed below could have fallen in one direction purely by inadvertence is less than 1 in 34 billion.

We now itemize 35 of the scientific errors and exaggerations in Al Gore’s movie. The first nine were listed by the judge in the High Court in London in October 2007 as being “errors.” The remaining 26 errors are just as inaccurate or exaggerated as the nine spelt out by the judge, who made it plain during the proceedings that the Court had not had time to consider more than these few errors. The judge found these errors serious enough to require the UK Government to pay substantial costs to the plaintiff.


ERROR 1
Sea level "rising 6 m"

Gore says that a sea-level rise of up to 6 m (20 ft) will be caused by melting of either West Antarctica or Greenland. Though Gore does not say that the sea-level rise will occur in the near future, the judge found that, in the context, it was clear that this is what he had meant, since he showed expensive graphical representations of the effect of his imagined 6 m (20 ft) sea-level rise on existing populations, and he quantified the numbers who would be displaced by the sea-level rise. The IPCC says sea-level increases up to 7 m (23 ft) above today’s levels have happened naturally in the past climate, and would only be likely to happen again after several millennia.

In the next 100 years, according to calculations based on figures in the IPCC’s 2007 report, these two ice sheets between them will add a little over 6 cm (2.5 inches) to sea level, not 6 m (this figure of 6 cm is 15% of the IPCC’s total central estimate of a 43 cm or 1 ft 5 in sea-level rise over the next century). Gore has accordingly exaggerated the official sea-level estimate by approaching 10,000 per cent.

Ms. Kreider says the IPCC estimates a sea-level rise of “59 cm” by 2100. She fails to point out that this amounts to less than 2 ft, not the 20 ft imagined by Gore. She also fails to point out that this is the IPCC’s upper estimate, on its most extreme scenario. And she fails to state that the IPCC, faced with a stream of peer-reviewed articles stating that sea-level rise is not a threat, has reduced this upper estimate from 3 ft in 2001 to less than 2 ft (i.e. half the mean centennial sea-level rise that has occurred since the end of the last Ice Age 10,000 years ago) in 2007.



Ms. Kreider says the IPCC’s 2007 sea-level calculations excluded contributions from Greenland and West Antarctica because they could not be quantified. However, Table SPM1 of the 2007 report quantifies the contributions of these two ice-sheets to sea-level rise as representing about 15% of the total change.

The report also mentions the possibility that there may be an unquantified further contribution in future from these two ice sheets arising from “dynamical ice flow.” However, the Greenland ice sheet rests in a depression in the bedrock created by its own weight, wherefore “dynamical ice flow” is impossible, and the IPCC says that temperature would have to be sustained at more than 5.5 degrees C above its present level for several millennia before half the Greenland ice sheet could melt, causing sea level to rise by some 3 m (10 ft).

Finally, the IPCC’s 2007 report estimates that the likelihood that humankind is having any influence on sea level at all is little better than 50:50. The judge was accordingly correct in finding that Gore’s presentation of the imagined imminent threat of a 6 m (20 ft) sea-level rise, with his account of the supposed impact on the present-day populations of Manhattan, the Netherlands, Bangladesh, etc., etc, was not a correct statement of the mainstream science on this question.
