William M. Gray said in 2006 that global warming became a political cause because of the lack of any other enemy following the end of the Cold War. He went on to say that its purpose was to exercise political influence, to try to introduce world government, and to control people, adding, "I have a demonic view on this." The TV documentary "The Great Global Warming Swindle" was made by Martin Durkin, who called global warming "a multi-billion-dollar worldwide industry, created by fanatically anti-industrial environmentalists." In the "Washington Times" in 2007 he said that his film would change history, and predicted that "in five years the idea that the greenhouse effect is the main reason behind global warming will be seen as total bunk." Climate change has also been called the "greatest scam in history" by John Coleman, who co-founded the Weather Channel. When questioned by the IPCC regarding his claims, he responded "The polar ice is increasing, not melting away. Polar Bears are increasing in number." In 2012, Donald Trump claimed that "The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive." In 2015, The Spectator published an article by Matt Ridley describing the "climate change agenda" as a "conspiracy against the poor." Climate change conspiracy has resulted in poor action or no action at all to effectively mitigate the damage done by global warming. In some countries like the United States of America, 40% of Americans believe that climate change is a hoax in spite of the fact that most climate scientists agree it is not. President Donald Trump has even pulled the United States out of the Paris Agreement, which was set up in the hopes of reducing global warming. There may be an ideology of climate change denial in some regions of the world, which would lead to disagreements over how to handle climate change and what should be done in the face of it. Steve Connor links the terms "hoax" and "conspiracy," saying, "Reading through the technical summary of this draft (IPCC) report, it is clear that no one could go away with the impression that climate change is some conspiratorial hoax by the science establishment, as some would have us believe." The documentary "The Great Global Warming Swindle" received criticism from several experts. George Monbiot described it as "the same old conspiracy theory that we’ve been hearing from the denial industry for the past ten years". Similarly, in response to James Delingpole, Monbiot stated that his Spectator article was "the usual conspiracy theories [...] working to suppress the truth, which presumably now includes virtually the entire scientific community and everyone from Shell to Greenpeace and The Sun to Science."
