Hiding real information and putting out lies was the norm since 1977.

To understand how corporate funding has contributed to the polarization of climate change in the United States, Farrell looked at 20 years’ worth of data, analyzing articles, texts, and policy papers produced by 164 organizations and more than 4,500 individuals who do not accept the science of climate change (that climate change is either not happening or not a product of human activity). The study also looked at funding from two key contrarian entities: the Koch Family Foundationsand ExxonMobil.

By analyzing both the networks of individuals and organizations that have participated in climate misinformation campaigns and the climate-related texts that those organizations produced between 1993 and 2013, Farrell found what he described to the Washington Post as an “ecosystem of influence” within groups that received corporate funding. Groups that received funding from Koch or Exxon were not only more likely to have written texts aimed at polarizing climate change, but were more likely to change the emphasis of their content over time. Beginning in 2008, groups that received funding were more likely than unfunded groups to produce texts stressing things like the idea that climate change is a long term cycle or that carbon dioxide is in fact good for the planet, key tenets of the climate misinformation campaign aimed at casting doubt on the scientific consensus. Groups that received funding consistently touted these themes, while groups with no funding didn’t show the same level of coordination.
