State of Fear is a 2004 techno-thriller novel by Michael Crichton, his fourteenth under his own name and twenty-fourth overall, in which eco-terrorists plot mass murder to publicize the danger of global warming. Despite being a work of fiction, the book contains many graphs and footnotes, two appendices, and a 20-page bibliography in support of Crichton's beliefs about global warming. Many climate scientists, science journalists, environmental groups, and science advocacy organisations dispute Crichton's views on the science as being error-filled and distorted.
