Investigative journalism by Inside Climate News (ICN) into Exxon’s internal documents revealed that the company was at the forefront of climate research, warning of the dangers posed by human-caused global warming from the late-1970s to the late-1980s. As Harvard climate historian Naomi Oreskes noted,
But Exxon was sending a different message, even though its own evidence contradicted its public claim that the science was highly uncertain and no one really knew whether the climate was changing or, if it was changing, what was causing it … Journalists and scientists have identified more than 30 different organizations funded by the company that have worked to undermine the scientific message and prevent policy action to control greenhouse gas emissions.
Exxon has responded to the ICN allegations by pointing out that over the past three decades, the company’s scientists have continued to publish peer-reviewed climate research.
Our scientists have contributed climate research and related policy analysis to more than 50 papers in peer-reviewed publications – all out in the open. They’ve participated in the United Nations Intergovernmental Panel on Climate Change since its inception – in 1988 – and were involved in the National Academy of Sciences review of the third U.S. National Climate Assessment Report.
Finally, I’ll note that we have long – and publicly – supported a revenue-neutral carbon tax as the most effective, transparent, and efficient way for governments to send a signal to consumers and the economy to reduce the use of carbon-based fuels.
While the ICN investigation focused on Exxon’s internal reports, Exxon’s spokesman pointed to the peer-reviewed scientific research published by the company’s scientists between 1983 and 2014 – 53 papers in all.
