Fact check
Is it true: Climate Change Denial Industry?
Yes — this is confirmed.
Harvard researchers Naomi Oreskes and Geoffrey Supran's analysis of Exxon's internal documents (published Science 2017, Nature 2020) showed Exxon's own scientists accurately predicted climate change from the 1970s onward — while Exxon's public messaging cast doubt on climate science. The 1998 "American Petroleum Institute Global Climate Science Team" memo explicitly outlined a disinformation strategy. Massachusetts v. ExxonMobil (2016), California cities' lawsuits, and NY AG cases have established through legal discovery that Exxon knew of climate risks while funding denial. The pattern (manufacturing doubt via think tanks, recycling of tobacco-industry PR consultants like APCO) is documented by Oreskes & Conway's Merchants of Doubt (2010). This is a confirmed corporate conspiracy.
