This was during the same time that the oil giant publicly doubted that warming was real and dismissed climate models’ accuracy. Exxon said its understanding of climate change evolved over the years and that critics are misunderstanding its earlier research.
“We’ve dug into not just to the language, the rhetoric in these documents, but also the data. And I’d say in that sense, our analysis really seals the deal on ‘Exxon knew’,” Supran said. It “gives us airtight evidence that Exxon Mobil accurately predicted global warming years before, then turned around and attacked the science underlying it.”
“This issue has come up several times in recent years and, in each case, our answer is the same: those who talk about how ‘Exxon Knew’ are wrong in their conclusions,” Spitler said in an emailed statement. “Some have sought to misrepresent facts and Exxon Mobil’s position on climate science, and its support for effective policy solutions, by recasting well intended, internal policy debates as an attempted company disinformation campaign.
Oil giants including Exxon and Shell were accused in congressional hearings in 2021 of spreading misinformation about climate, but executives from the companies denied the accusations. There’s a difference between the “hype and spin” that companies do to get you to buy a product or politicians do to get your vote and an “outright lie ... misrepresenting factual information and that’s what Exxon did,” Oreskes said.Advertisement
