Debunking a Climate-Change Skeptic

DJRumpy writes "The Danish political scientist Bjørn Lomborg won fame and fans by arguing that many of the alarms sounded by environmental activists and scientists — that species are going extinct at a dangerous rate, that forests are disappearing, that climate change could be catastrophic — are bogus. A big reason Lomborg was taken seriously is that both of his books, The Skeptical Environmentalist (in 2001) and Cool It (in 2007), have extensive references, giving a seemingly authoritative source for every one of his controversial assertions. So in a display of altruistic masochism that we should all be grateful for (just as we're grateful that some people are willing to be dairy farmers), author Howard Friel has checked every single citation in Cool It. The result is The Lomborg Deception, which is being published by Yale University Press next month. It reveals that Lomborg's work is 'a mirage,' writes biologist Thomas Lovejoy in the foreword. '[I]t is a house of cards. Friel has used real scholarship to reveal the flimsy nature' of Lomborg's work."

Re:I usually just point out

I've never heard of the Daily Mail, much less read it. Please read Lomborg's (relatively short) rebuttal.

Re:Absence of Evidence

Not at all. Source code shows precisely how calculations were carried out.

When you have an algorithm, for instance, that produces the 'hockey stick' even when fed random numbers, that is positive proof that the numbers have been cooked - manipulated in order to produce the predetermined outcome. That isnt science.

Your example shows Friel is a lying bastard

"Without reading both books, I can't take sides on the merits. But I will say some of the stuff in TFA sets off my alarms--like spending a footnote on a WHO report just to cite the population of Europe."

When doing math, statistical sources matter. But here we have something substantial to discuss. Is Lomborg dishonest in this case? Read along for the answer!

Friel: "But Lomborg's only source for these figures—a chart in the statistical annex of a 2004 World Health Organization report—contains
no data on human mortality due to excess heat or cold. In fact, the words "excess heat" and "excess cold" make no appearance in the WHO document; neither does the word "heat," and the word "cold" appears only once in a reference unrelated to death due to excess cold.

Lomborg's reference to the WHO document, which allegedly supports his claim that two hundred thousand people die each year in Europe from excess heat, reads in its entirety: "207,000, based on a simple average of the available cold and heat deaths per million, cautiously excluding London and using WHO’s estimate for Europe’s population of 878 million (WHO, 2004a:121).”

However, page 121 of the 2004 WHO report—The World Health Report 2004: Changing History— which is what this source references, lists no data on cold- and heatrelated deaths per million, or for cold- and heat-related deaths in any context.

  Likewise, Lomborg's very next reference-to support his claim that 1.5 million Europeans die annually from excess cold - reads in its entirety: "1.48 million, estimated in the same way as total heat deaths."

Thus, Lomborg's references indicate that page 121 of the 2004 WHO report is the source of his estimates of annual heat- and cold-related deaths in Europe; however, this page in the WHO report lists no statistics for either cold- or heat-related deaths. Consequently, there is no apparent basis here or elsewhere in Cool It for Lomborg's claim that 1.5 million Europeans die annually from excess cold. [LD, p. 86, emphasis added]

Lomborg: "In fact, the text and first endnote in this section make it very clear where the figures are sourced from: “Based on the summary of the biggest European heat and cold study (Keatinge, et al., 2000, p. 672).” (p. 170).

In the UK edition of the book, there is even a figure with the numbers, with the further explanation: “estimated in the text, using Keatinge et al., 2000:672.” (p. 233, CIUK) Friel’s claim that I relied on a WHO document that does not support my case is astonishing and profoundly disingenuous.

I clearly used the WHO report solely to provide an estimate of Europe’s population (because WHO uses the standard geographical definition of Europe to the Ural Mountains).This is evident in the text that Friel himself quoted: “and using WHO’s estimate for Europe’s population of 878 million (WHO, 2004a:121).”

Finding this study on Google Scholar took me all of two seconds using the reference provided by Lomborg (in his book).

The quote is confirmed by Google Books:

http://books.google.se/books?q=estimated+in+the+text,+using+Keatinge+et+al.,+2000:672&btnG=S%C3%B6k+i+b%C3%B6cker

In short, from this example, picked by you - not me, it plainly evident that is Friels honesty or literacy that should be in question, not Lomborgs. This is likely to be representative of the "debunking" in its entirety, going from what I have read of the rebuttal so far.

The problem is it was neither Billy nor Jane who was the culprit. The problem with the global warming / climate change people is that all they are doing is arguing for a massive redistribution of wealth. The issue is a human behavior problem not a take the money from the rich and throw it to some despot nation somewhere else. The other problem with the whole climate change thing is that, yes, the climate does change. Oversimplifying, yes, but the earth was really hot, then it got really cold, then it heated up again. Trying to make the climate stop changing would be like trying to stop the magnetic field's progression toward a flip.
