On March 9, 2017, in an interview on CNBC's Squawk Box, Pruitt stated that he "would not agree that" carbon dioxide is "a primary contributor to the global warming that we see" backing up his claim by stating that "measuring with precision human activity on the climate is something very challenging to do and there's tremendous disagreement about the degree of impact." This was in direct contradiction with EPA's public stance that was published on their official website which stated: "Carbon dioxide is the primary greenhouse gas that is contributing to recent climate change". By April 28—the day before the climate change mass protests—EPA announced that the website "would be 'undergoing changes' to better represent the new direction the agency is taking" which included "the removal of several agency websites containing detailed climate data and scientific information" including the site that "had been cited to challenge Pruitt's Squawk Box statements." A March 9 analysis by fact-checking website "Snopes.com" found that "Pruitt's statements to CNBC are misrepresentative of the scientific consensus on carbon dioxide's role as a greenhouse gas—a consensus that has essentially existed for more than a century." "The Atlantic" published an article on the same day, pointing out that in 2007, the United States Supreme Court had acknowledged the link between carbon dioxide and global warming—in 2013 the Intergovernmental Panel on Climate Change stated the probability of carbon dioxide causing global warming was at least 95%.
