Notes: According to Desmog, Principia Scientific International (PSI) is an organization based in the United Kingdom which promotes fringe views and material to claim that carbon dioxide is not a greenhouse gas. PSI was formed in 2010 around the time they published their first book, titled Slaying the Sky Dragon: Death of the Greenhouse Gas Theory. Our review of the website reveals a climate denial website that promotes climate change as a grand conspiracy with scientists “fudging” data. Overall, this is a pseudoscience website. (D.
