BBC News reports:
In 1991, the trade body that represents electrical companies in the U.S., the Edison Electric Institute, created a campaign called the Information Council for the Environment which aimed to “Reposition global warming as theory (not fact)”. Some details of the campaign were leaked to the New York Times. “They ran advertising campaigns designed to undermine public support, cherry picking the data to say, ‘Well if the world is warming up, why is Kentucky getting colder?’ They asked rhetorical questions designed to create confusion, to create doubt,” argued Naomi Oreskes, professor of the history of science at Harvard University and co-author of Merchants of Doubt. But back in the 1990 there were many campaigns like this…
Most of the organisations opposing or denying climate change science were right-wing think tanks, who tended to be passionately anti-regulation. These groups made convenient allies for the oil industry, as they would argue against action on climate change on ideological grounds. Jerry Taylor spent 23 years with the Cato Institute — one of those right wing think tanks — latterly as vice president. Before he left in 2014, he would regularly appear on TV and radio, insisting that the science of climate change was uncertain and there was no need to act.
Now, he realises his arguments were based on a misinterpretation of the science, and he regrets the impact he’s had on the debate.
Harvard historian Naomi Oreskes discovered leading climate-change skeptics had also been prominent skeptics on the dangers of cigarette smoking. “That was a Eureka moment,” Oreskes tells BBC News. “We realised this was not a scientific debate.”
Decades before the energy industry tried to undermine the case for climate change, tobacco companies had used the same techniques to challenge the emerging links between smoking and lung cancer in the 1950s… As a later document by tobacco company Brown and Williamson summarised the approach: “Doubt is our product, since it is the best means of competing with the ‘body of fact’ that exists in the minds of the general public.” Naomi Oreskes says this understanding of the power of doubt is vital. “They realise they can’t win this battle by making a false claim that sooner or later would be exposed. But if they can create doubt, that would be sufficient — because if people are confused about the issue, there’s a good chance they’ll just keep smoking….”
Academics like David Michaels, author of The Triumph of Doubt, fear the use of uncertainty in the past to confuse the public and undermine science has contributed to a dangerous erosion of trust in facts and experts across the globe today, far beyond climate science or the dangers of tobacco. He cites public attitudes to modern issues like the safety of 5G, vaccinations — and coronavirus.
“By cynically manipulating and distorting scientific evidence, the manufacturers of doubt have seeded in much of the public a cynicism about science, making it far more difficult to convince people that science provides useful — in some cases, vitally important — information.
