The main players? Rich oil billionaires David and Charles Koch.
The Koch family of industrialists and businessmen is most notable for their control of Koch Industries, the second largest privately owned company in the United States. The family business was started by Fred C. Koch, who developed a new method for refining heavy oil into gasoline. Fred’s four sons became involved in litigation against each other in the 1980s and 1990s. According to the Koch Family Foundations and Philanthropy website, “the foundations and the individual giving of Koch family members” have financially supported organizations “fostering entrepreneurship, education, human services, at-risk youth, arts and culture, and medical research.” 
David H. Koch and Charles G. Koch—the two brothers still with Koch Industries—are affiliated with the Koch family foundations. Annual revenues for Koch Industries have been “estimated to be a hundred billion dollars.” 
The goal of their conspiracy? To promote Fear Uncertainty & Doubt (FUD) against the science of global warming by funding various political ‘think tanks’, anti-climate workplace groups, retirement village groups, and even church groups.
