Please listen to this interview 15:10 onwards.
Or you could watch it here...
and here...
Richard Bacon shows off his stupidity. The 97% figure as demolished by James Delingpole is as I have blogged previously.
Richard Bacon didn't sound a) impartial or b) knowledgeable...In fact have you ever heard him sound so angry throughout an interview and so triumphant when he thought (usually incorrectly) that he'd made a good point? Are BBC interviewers meant to treat interviewees like this? Can anyone think of another interviewee that Richard Bacon has so taken against?
I wonder if Richard bacon will find the time in his busy schedule to check that 97% statistic that so upset him. In case he or @declanmurray78 need some help here's a link that might help and in case you two cannot follwo a link, here's the meat of the matter:

'How do we know there’s a scientific consensus on climate change? Pundits and the press tell us so. And how do the pundits and the press know? Until recently, they typically pointed to the number 2500 – that’s the number of scientists associated with the United Nations Intergovernmental Panel on Climate Change. Those 2500, the pundits and the press believed, had endorsed the IPCC position. [1]
To their embarrassment, most of the pundits and press discovered that they were mistaken – those 2500 scientists hadn’t endorsed the IPCC’s conclusions, they had merely reviewed some part or other of the IPCC’s mammoth studies. To add to their embarrassment, many of those reviewers from within the IPCC establishment actually disagreed with the IPCC’s conclusions, sometimes vehemently.
The upshot? The punditry looked for and recently found an alternate number to tout — “97% of the world’s climate scientists” accept the consensus, articles in the Washington Post and elsewhere have begun to claim.
This number will prove a new embarrassment to the pundits and press who use it. The number stems from a 2009 online survey of 10,257 earth scientists, conducted by two researchers at the University of Illinois. The survey results must have deeply disappointed the researchers – in the end, they chose to highlight the views of a subgroup of just 77 scientists, 75 of whom thought humans contributed to climate change. The ratio 75/77 produces the 97% figure that pundits now tout.
The two researchers started by altogether excluding from their survey the thousands of scientists most likely to think that the Sun, or planetary movements, might have something to do with climate on Earth – out were the solar scientists, space scientists, cosmologists, physicists, meteorologists and astronomers. That left the 10,257 scientists in disciplines like geology, oceanography, paleontology, and geochemistry that were somehow deemed more worthy of being included in the consensus. The two researchers also decided that scientific accomplishment should not be a factor in who could answer – those surveyed were determined by their place of employment (an academic or a governmental institution). Neither was academic qualification a factor – about 1,000 of those surveyed did not have a PhD, some didn’t even have a master’s diploma.
To encourage a high participation among these remaining disciplines, the two researchers decided on a quickie survey that would take less than two minutes to complete, and would be done online, saving the respondents the hassle of mailing a reply. Nevertheless, most didn’t consider the quickie survey worthy of response –just 3146, or 30.7%, answered the two questions on the survey:
1. When compared with pre-1800s levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant?
2. Do you think human activity is a significant contributing factor in changing mean global temperatures?
The questions were actually non-questions. From my discussions with literally hundreds of skeptical scientists over the past few years, I know of none who claims that the planet hasn’t warmed since the 1700s, and almost none who think that humans haven’t contributed in some way to the recent warming – quite apart from carbon dioxide emissions, few would doubt that the creation of cities and the clearing of forests for agricultural lands have affected the climate. When pressed for a figure, global warming skeptics might say that human are responsible for 10% or 15% of the warming; some skeptics place the upper bound of man’s contribution at 35%. The skeptics only deny that humans played a dominant role in Earth’s warming.
Surprisingly, just 90% of those who responded to the first question believed that temperatures had risen – I would have expected a figure closer to 100%, since Earth was in the Little Ice Age in the centuries immediately preceding 1800. But perhaps some of the responders interpreted the question to include the past 1000 years, when Earth was in the Medieval Warm Period, generally thought to be warmer than today.
As for the second question, 82% of the earth scientists replied that that human activity had significantly contributed to the warming. Here the vagueness of the question comes into play. Since skeptics believe that human activity been a contributing factor, their answer would have turned on whether they consider a 10% or 15% or 35% increase to be a significant contributing factor. Some would, some wouldn’t.
In any case, the two researchers must have feared that an 82% figure would fall short of a convincing consensus – almost one in five wasn’t blaming humans for global warming — so they looked for subsets that would yield a higher percentage. They found it – almost — in those whose recent published peer-reviewed research fell primarily in the climate change field. But the percentage still fell short of the researchers’ ideal. So they made another cut, allowing only the research conducted by those earth scientists who identified themselves as climate scientists.
Once all these cuts were made, 75 out of 77 scientists of unknown qualifications were left endorsing the global warming orthodoxy. The two researchers were then satisfied with their findings [2]. Are you?

ReplyDeleteOr you could try the paper "Expert Credibility in climate change", published in 2010 in PNAS (one of the world's top 5 science journals across all disciplines). This paper had a sample size of 1372 climate scientists. Major conclusions of this paper included that not only did 97-98% of climate scientists most actively in publishing in the field agree with the tenets of anthropogenic climate change, but also that the relative climate expertise and scientific prominence of the researchers unconvinced of ACC are substantially below that of the convinced researcher
ReplyDeleteAnon 22:43: Or you could note that PNAS 'used Google Scholar instead of an academic database. They searched only in English, despite the global nature of climate science. They got names wrong. They got job titles wrong. They got incorrect numbers of publications and citations.
ReplyDelete...the highly respected Spencer Weart dismissed the paper as rubbish, saying it should not have been published.'
As to PNAS, are you 100% sure of their impartiality in this area?
Given that your website header boldly states "I AM NOT A SHEEP, I HAVE MY OWN MIND", I couldn't help but be slightly amused that you've simply copy-pasted someone else's ruminations from wattsupwiththat. But anyway, the searching was performed with the authors' names and the word climate. The vast majority of scientific papers are published in English because of the simple fact that this is a language that most of the scientific community speaks and uses for publications. Non-English language journals normally have a very low impact factor. Even if it is in a foreign language however, it is still likely to use the English language word "climate" in its search terms because of the importance of this, and the fact that publishers want to get their publications noticed (its not unusual for foreign language journals to supply entire abstracts in English, even if the article is not).
ReplyDeleteThere are not author names or titles within the article itself, so I'm guessing the mistakes are in the references section. If this is the case, I don't think that typographical errors in entering references into a citation manager will damage the conclusions gained from the data in any way.
The use of Google scholar is discussed in the paper and it noted that this produces similar publication and citation counts to those seen with other peer-review-only citation indices. A reference is also given to a study whose sole goal was to establish the veracity of that statement.
PNAS is a very highly respected scientific journal. Papers in such journals are not published based upon a pre-conceived agenda, and feedback is welcomed, if not encouraged. If you'd looked up the paper you would have found criticisms and rebuttals of the article published in the very same journal. but you didn't look it up did you, you just ran over to wattsupwiththat for an opinion that you could follow unquestioningly... like a sheep.
I listened to this and the underlying Delingpole problem is the same that it ever was. If he has a serious point to make, it is lost in a stomach churning display of arrogance and lack of emotional intelligence. He just did as much for the pro-warming argument on R5 as Al Gore would given any similar forum.
ReplyDeleteYou found Delingpole's arrogance more stomach-churning than Bacon's ignorance?
ReplyDeleteAnon 22:43 - I note that you have not responded to my reply comment. While you ponder that you could also consider the 31,000 scientists, who all co-signed the following statement: 'The proposed limits on greenhouse gases would harm the environment, hinder the advance of science and technology, and damage the health and welfare of mankind.
ReplyDeleteThere is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth.'
Anon: I note that you have not answered my point yet. I suppose that it's easier to work out where I have got my material from than to address the 97% point.
ReplyDeleteI will only post further comments from you if you address this point first. As for me being a sheep, you are entitled to your view, but I'm not the one who just accepts what they are spoon-fed.
You didn't like the study which you knew of, so I gave you an alternative. The alternative was from a highly credible peer-reviewed journal. It used a much larger sample size of climate scientists. The scientist were all qualified in their field, and publication records were well know. Each scientist's position on the issue were clearly understood by their choice to agree with or directly endorse the tenets of the IPCC fourth assessment report, or to sign up to statements strongly dissenting from the views of the IPCC. [That IPCC report said that it is “very likely” that anthropogenic greenhouse gases have been responsible for “most” of the “unequivocal” warming of the Earth's average global temperature in the second half of the 20th century,]. So the study I gave you dealt with the concerns that were raised in the 2009 study that you have referred to and it still arrived at the same 97% figure. In providing you with this study I have answered your stated concerns with the 97% figure.
ReplyDeleteThe qualification of "scientist" for signing that statement that you referred to in the comment above was an undergraduate degree in any scientific discipline. So for a start, what qualifies those 31000 signatories to give an informed opinion on ACC is anybody's guess. But that may as well be by-the-by because the name and degrees on the list cannot be verified as real by anyone outside OISM (who produced the petition). It does not stand up to the most basic tests of scientific credibility. But just for fun let's use the OISM's definition of "scientist" to look at the potential sample size from which the 31000 figure arose. There have been over 10.6 million science graduates in the US since 1970. The 31000 figure therefore represents an agreement rate of less than 0.3% of scientists across any discipline with the 'skeptical' statement.
Anon: You twist and twist but we both know the truth don't we? NCF
