Who is behind climate change deniers?

WHEN the tobacco industry was feeling the heat from scientists who showed that smoking caused cancer, it took decisive action.

It engaged in a decades-long public relations campaign to undermine the medical research and discredit the scientists. The aim was not to prove tobacco harmless but to cast doubt on the science.

In May this year, the multibillion-dollar oil giant Exxon-Mobil acknowledged that it had been doing something similar. It announced that it would cease funding nine groups that had fuelled a global campaign to deny climate change.

Exxon's decision comes after a shareholder revolt by members of the Rockefeller family and big superannuation funds to get the oil giant to take climate change more seriously. Exxon (once Standard Oil) was founded by the legendary John D. Rockefeller. Last year, the chairman of the US House of Representatives oversight committee on science and technology, Brad Miller, said Exxon's support for sceptics "appears to be an effort to distort public discussion".

The funding of an array of think tanks and institutes that house climate sceptics and deniers also worried Britain's premier scientific body, the Royal Society. It found that in 2005 Exxon distributed nearly $3 million to 39 groups that "misrepresented the science of climate change by outright denial of the evidence that greenhouse gases are driving climate change". It asked Exxon to stop the funding and its protests helped force Exxon's recent retreat.

The chief scientist of New Zealand's National Institute of Water and Atmospheric research, Dr Jim Salinger, knows all about misrepresentation. Two months ago, he was named by an Exxon-funded group, the Heartland Institute, as a scientist whose work undermined the theory that burning carbon was a cause of global warming.

The Heartland Institute — essentially a free market lobby — emphasises that "the climate is always changing". Salinger's research studied variation in climate, so his research was enrolled in the denial campaign.

Variations in the climate are normal, Salinger said, but this did not in any way weaken conclusions about the dangers of burning oil and coal. "Global warming is real," he said, and demanded reference to his work be removed. The institute refused. The Heartland Institute received almost $800,000 from Exxon, according to Greenpeace's research based on Exxon's corporate giving disclosures.

Another regular piece of evidence in the denial lobby's PR campaign is the "Oregon Petition". This urges the US Government to reject the Kyoto Protocol and claims there is "no convincing scientific evidence" for global warming. It is said to be signed by 31,000 graduates, most of whom appear to have nothing to do with climate science.

The petition originated in 1998 with a scientist, Dr Frederick Seitz, who had been president of the US National Academy of Science in the 1960s (and a tobacco consultant in the 1970s). The petition was accompanied by a purported review of the science that was co-published by the George C. Marshall Institute. This institute received at least $715,000 from Exxon Mobil since 1998.

Claims about the world cooling, not warming, are common in the world of deniers. Cardinal George Pell referred to this possibility recently.

In his recent book Heat, George Monbiot gives the example of the TV presenter and botanist, David Bellamy, who is also a climate sceptic. He told the New Scientist in 2005 that most glaciers in the world are growing, not shrinking. He said his evidence came from the World Glacier Monitoring Service in Switzerland, a reputable body. When Monbiot checked the service they said that the Bellamy claim was "complete bullshit". Glaciers are retreating.

In Australia, the main group that tries to undermine the science of global warming is the Lavoisier Group. It maintains a website with links to the Competitive Enterprise Institute (over $2 million from Exxon), Science and Environmental Policy Project ($20,000) and the Centre for the Study of Carbon Dioxide (at least $100,000).

The Lavoisier group is certainly influential in the Federal Opposition. A senior figure in the group told Guy Pearse, author of High and Dry, a study of climate policy in Australia, that there "is an understanding in cabinet that all the science is crap".

But perhaps the oil companies' PR campaign is not the main reason for the success of the climate change deniers. There are at least three others. First, the implications of the science are frightening. Shifting to renewable energy will be costly and disruptive. Second, doubt is an easy product to sell. Climate denial tells us what we all secretly want to hear. Third, science is portrayed by the free market right as a political "orthodoxy" rather than objective knowledge.

The tide slowly turned on tobacco denial and the science was accepted in the end. But climate is different. There are no "smoke-free areas" on the planet. Climate denial may turn out to be the world's most deadly PR campaign.
