As is the case with any Manufactured Doubt campaign, a respected scientist was needed to lead the battle. One such scientist was Dr. Frederick Seitz, a physicist who in the 1960s chaired the organization many feel to be the most prestigious science organization in the world--the National Academy of Sciences. Seitz took a position as a paid consultant for R.J. Reynolds tobacco company beginning in 1978, so was well-versed in the art of Manufactured Doubt. According to the excellent new book, Climate Cover-up, written by desmogblog.com co-founder James Hoggan and Richard Littlemore, over a 10-year period Seitz was responsible for handing out $45 million in tobacco company money to researchers who overwhelmingly failed to link tobacco to anything the least bit negative. Seitz received over $900,000 in compensation for his efforts. He later became a founder of the George C. Marshall Institute, and used his old National Academy of Sciences affiliation to lend credibility to his attacks on global warming science until his death in 2008 at the age of ninety-six. It was Seitz who launched the "Oregon Petition", which contains the signatures of more than 34,000 scientists saying global warming is probably natural and not a crisis. The petition is a regular feature of the Manufactured Doubt campaign against human-caused global warming. The petition lists the "Oregon Institute of Science and Medicine" as its parent organization. According to Climate Cover-up, the Institute is a farm shed situated a couple of miles outside of Cave Junction, OR (population 17,000). The Institute lists seven faculty members, two of whom are dead, and has no ongoing research and no students. It publishes creationist-friendly homeschooler curriculums books on surviving nuclear war. The petition was sent to scientists and was accompanied by a 12-page review printed in exactly the same style used for the prestigious journal, Proceedings of the National Academy of Sciences. A letter from Seitz, who is prominently identified as a former National Academy of Sciences president, accompanied the petition and review. Naturally, many recipients took this to be an official National Academy of Sciences communication, and signed the petition as a result. The National Academy issued a statement in April 2008, clarifying that it had not issued the petition, and that its position on global warming was the opposite. The petition contains no contact information for the signers, making it impossible to verify. In its August 2006 issue, Scientific American presented its attempt to verify the petition. They found that the scientists were almost all people with undergraduate degrees, with no record of research and no expertise in climatology. Scientific American contacted a random sample of 26 of the 1,400 signatories claiming to have a Ph.D. in a climate related science. Eleven said they agreed with the petition, six said they would not sign the petition today, three did not remember the petition, one had died, and five did not respond.
I could say much more about the Manufactured Doubt campaign being waged against the science of climate change and global warming, but it would fill an entire book. In fact, it has, and I recommend reading Climate Cover-up to learn more. The main author, James Hoggan, owns a Canadian public relations firm, and is intimately familiar with how public relations campaigns work. Suffice to say, the Manufactured Doubt campaign against global warming--funded by the richest corporations in world history--is probably the most extensive and expensive such effort ever. We don't really know how much money the fossil fuel industry has pumped into its Manufactured Doubt campaign, since they don't have to tell us. The website exxonsecrets.org estimates that ExxonMobil alone spent $20 million between 1998 - 2007 on the effort. An analysis done by Desmogblog's Kevin Grandia done in January 2009 found that skeptical global warming content on the web had doubled over the past year. Someone is paying for all that content.
Lobbyists, not skeptical scientists
The history of the Manufactured Doubt industry provides clear lessons in evaluating the validity of their attacks on the published peer-reviewed climate change science. One should trust that the think tanks and allied "skeptic" bloggers such as Steve McIntyre of Climate Audit and Anthony Watts of Watts Up With That will give information designed to protect the profits of the fossil fuel industry. Yes, there are respected scientists with impressive credentials that these think tanks use to voice their views, but these scientists have given up their objectivity and are now working as lobbyists. I don't like to call them skeptics, because all good scientists should be skeptics. Rather, the think tanks scientists are contrarians, bent on discrediting an accepted body of published scientific research for the benefit of the richest and most powerful corporations in history. Virtually none of the "sound science" they are pushing would ever get published in a serious peer-reviewed scientific journal, and indeed the contrarians are not scientific researchers. They are lobbyists. Many of them seem to believe their tactics are justified, since they are fighting a righteous war against eco-freaks determined to trash the economy.
I will give a small amount of credit to some of their work, however. I have at times picked up some useful information from the contrarians, and have used it to temper my blogs to make them more balanced. For example, I no longer rely just on the National Climatic Data Center for my monthly climate summaries, but instead look at data from NASA and the UK HADCRU source as well. When the Hurricane Season of 2005 brought unfounded claims that global warming was to blame for Hurricane Katrina, and a rather flawed paper by researchers at Georgia Tech showing a large increase in global Category 4 and 5 hurricanes, I found myself agreeing with the contrarians' analysis of the matter, and my blogs at the time reflected this.
The contrarians and the hacked CRU emails
A hacker broke into an email server at the Climate Research Unit of the UK's University of East Anglia last week and posted ten years worth of private email exchanges between leading scientists who've published research linking humans to climate change. Naturally, the contrarians have seized upon this golden opportunity, and are working hard to discredit several of these scientists. You'll hear claims by some contrarians that the emails discovered invalidate the whole theory of human-caused global warming. Well, all I can say is, consider the source. We can trust the contrarians to say whatever is in the best interests of the fossil fuel industry. What I see when I read the various stolen emails and explanations posted at Realclimate.org is scientists acting as scientists--pursuing the truth. I can see no clear evidence that calls into question the scientific validity of the research done by the scientists victimized by the stolen emails. There is no sign of a conspiracy to alter data to fit a pre-conceived ideological view. Rather, I see dedicated scientists attempting to make the truth known in face of what is probably the world's most pervasive and best-funded disinformation campaign against science in history. Even if every bit of mud slung at these scientists were true, the body of scientific work supporting the theory of human-caused climate change--which spans hundreds of thousands of scientific papers written by tens of thousands of scientists in dozens of different scientific disciplines--is too vast to be budged by the flaws in the works of the three or four scientists being subject to the fiercest attacks.
