Smithsonian: "There is a very well-funded, well-orchestrated climate change-denial movement, one funded by powerful people with very deep pockets. In a new and incredibly thorough study, Drexel University sociologist Robert Brulle took a deep dive into the financial structure of the climate deniers, to see who is holding the purse strings.
"According to Brulle's research, the 91 think tanks and advocacy organizations and trade associations that make up the American climate denial industry pull down just shy of a billion dollars each year, money used to lobby or sway public opinion on climate change and other issues. (The grand total also includes funds used to support initiatives unrelated to climate change denial, as explained in a quote Brulle gave to The Guardian: 'Since the majority of the organizations are multiple focus organizations, not all of this income was devoted to climate change activities.'”
