Presentation by Aaron Maisto and John Hall The Novel: State of Fear A science fiction thriller. Involves an eco-terrorist plot to keep the public in a ?state of fear? regarding global warming, which involves both subtle manipulation of data and more diabolical schemes such as creating artificial tsunamis. Although much of the book is clearly fictional, it does include data and observations from real scientists. Critiques and Commentary The novel received strong criticism from leading climate scientists, science journalists, and environmental groups for inaccuracies and misleading information. Sixteen of 18 top U.S. climate scientists interviewed by Knight Ridder said that the Harvard-trained author is bending scientific data and distorting research.

Research the meaning of null hypothesis. Describe how and why it is used in experimental design. Properly cite your reference. In statistical inference of observed data of a scientific experiment, the null hypothesis refers to a general or default position: that there is no relationship between two measured phenomena,[1] or that a potential medical treatment has no effect.[2] Rejecting or disproving the null hypothesis ? and thus concluding that there are grounds for believing that there is a relationship between two phenomena or that a potential treatment has a measurable effect ? is a central task in the modern practice of science, and gives a precise sense in which a claim is capable of being proven false.
