Problem: Background: 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.
Context: 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.
Question: why were his views challenged
Answer: 

IN: The Undertones are a punk rock/new wave band formed in Derry, Northern Ireland, in 1974. From 1975 to 1983, the Undertones consisted of Feargal Sharkey (vocals), John O'Neill (rhythm guitar, vocals), Damian O'Neill (lead guitar, vocals), Michael Bradley (bass, vocals) and Billy Doherty (drums). Much of the earlier Undertones material drew influence from punk rock and new wave; the Undertones also incorporated elements of rock, glam rock and post-punk into material released after 1979, before citing soul and Motown as the influence for the material released upon their final album. The Undertones released thirteen singles and four studio albums between 1978 and 1983 before Sharkey announced his intention to leave the band in May 1983, citing musical differences as the reason for the break up.

By 1977 the band were performing their own three-chord pop punk material, which was performed alongside cover versions at concerts, primarily at The Casbah, where the band began to perform in February. The Undertones had occasionally earned money at venues where they had performed throughout 1976, but these gigs at The Casbah were the first performances for which the Undertones were paid on a regular basis, as performing at The Casbah earned the group up to PS40 a week. This inspired the band to write and rehearse further material, as a means of remaining a popular act at this venue. By mid-year, the concerts the Undertones performed would include the song "Teenage Kicks", which had been written by guitarist John O'Neill in mid-1977. The gigs performed at The Casbah gave the Undertones increased confidence in their musical ability, and in June 1977 they performed concerts outside Derry for the first time, supporting a Dublin punk group named The Radiators from Space.  In March 1978, the Undertones recorded a demo tape at Magee University in Derry and sent copies of the tape to various record companies in the hope of securing a record deal, but only received official letters of rejection. The band had also sent a copy of their recordings to influential BBC Radio 1 DJ John Peel, requesting he play the songs on his radio programme. Peel replied to the band, offering to pay for a recording session in Belfast. On 16 June 1978, the band recorded their debut four-song EP "Teenage Kicks" on a budget of only PS200. The EP was engineered by Davy Shannon at Wizard Sound Studios, Belfast - and was released on Belfast's Good Vibrations record label. The title song became a hit with support from John Peel, who considered Teenage Kicks his all-time favourite song, an opinion he held until his death in 2004.  Seymour Stein, the president of Sire Records - in London on business - heard John Peel play "Teenage Kicks" on BBC Radio 1 and became interested in the band. Stein sent a London-based representative named Paul McNally to Derry to discuss a record deal with the band. McNally saw the band play live in what would ultimately prove to be their final performance at The Casbah on 29 September 1978. The following day, McNally convened with the Undertones to discuss a record contract. Three members of the band signed the proposed contract on this date, with the understanding that Feargal Sharkey and Michael Bradley would discuss negotiations to the contract with Seymour Stein in person in London.

OUT: performing at The Casbah earned the group up to PS40 a week.

Background: Michael Andrew McKagan grew up in Seattle's largely working-class University District, the youngest of eight children born to Marie and Elmer "Mac" McKagan. He has been called "Duff" since toddlerhood, to which he once referred as "an Irish thing". Following his parents' divorce, his mother supported the family by taking a job as a medical stenographer. He was taught how to play bass by his brother Bruce, further developing his skills by playing along with the albums 1999 by Prince and Damaged by Black Flag.
Context: In 1979, at the age of 15, McKagan formed the punk band the Vains, in which he played bass; they released the single "School Jerks" in 1980. During this time, he also played guitar in the punk band the Living, which opened shows for Husker Du and D.O.A., which developed a devoted following.  In 1980, McKagan joined the pop-punk band the Fastbacks as their drummer. He appeared on their 1981 debut single "It's Your Birthday", which was issued on guitarist Kurt Bloch's label No Threes Records, and on the song "Someone Else's Room", which was included on the Seattle Syndrome Volume One compilation album, also released in 1981.  In 1982, McKagan became the drummer for the hardcore punk band The Fartz, with whom he recorded several demos, five of which were included on their 1990 album You, We See You Crawling. After several line-up changes, The Fartz evolved into the post-punk band 10 Minute Warning, for which McKagan played guitar.  In 1983, McKagan moved to Los Angeles, California, with one of his brothers where he found work as an appetizer server at a Black Angus restaurant in Northridge. Answering an ad for a bass guitarist in a local newspaper, he met guitarist Slash and drummer Steven Adler, with whom he formed the short-lived band Road Crew. They auditioned a number of singers, including one-time Black Flag vocalist Ron Reyes, and worked on material that included the main riff of what would become the Guns N' Roses song "Rocket Queen". Slash eventually disbanded the group due to them not being able to find a singer, as well as Adler's lack of work ethic compared to himself and McKagan.
