John Michael Crichton (; October 23, 1942 - November 4, 2008) was an American author, screenwriter, film director and producer best known for his work in the science fiction, thriller, and medical fiction genres. His books have sold over 200 million copies worldwide, and over a dozen have been adapted into films. His literary works are usually within the action genre and heavily feature technology. His novels epitomize the techno-thriller genre of literature, often exploring technology and failures of human interaction with it, especially resulting in catastrophes with biotechnology.

Many of Crichton's publicly expressed views, particularly on subjects like the global warming controversy, have been contested by a number of scientists and commentators. An example is meteorologist Jeffrey Masters's review of State of Fear: Flawed or misleading presentations of global warming science exist in the book, including those on Arctic sea ice thinning, correction of land-based temperature measurements for the urban heat island effect, and satellite vs. ground-based measurements of Earth's warming. I will spare the reader additional details. On the positive side, Crichton does emphasize the little-appreciated fact that while most of the world has been warming the past few decades, most of Antarctica has seen a cooling trend. The Antarctic ice sheet is actually expected to increase in mass over the next 100 years due to increased precipitation, according to the IPCC." Peter Doran, author of the paper in the January 2002 issue of Nature, which reported the finding referred to above that some areas of Antarctica had cooled between 1986 and 2000, wrote an opinion piece in the July 27, 2006, The New York Times in which he stated "Our results have been misused as 'evidence' against global warming by Michael Crichton in his novel State of Fear." Al Gore said on March 21, 2007, before a U.S. House committee: "The planet has a fever. If your baby has a fever, you go to the doctor [...] if your doctor tells you you need to intervene here, you don't say 'Well, I read a science fiction novel that tells me it's not a problem'." This has been interpreted by several commentators as a reference to State of Fear.Answer this question using a quote from the following article:
