William Connolley

William Michael Connolley (born April 12, 1964) is a software engineer in Cambridge, England. Connolley was, until December 2007, Senior Scientific Officer in the Physical Sciences Division in the Antarctic Climate and the Earth System project at the British Antarctic Survey, where he worked as a climate modeller.


Connolley holds a Bachelor of Arts in mathematics and Doctor of Philosophy from the University of Oxford for his work on numerical analysis. [W.M. Connolley, "Preconditioning of iterative methods for linearised or linear systems" (diss. Oxford, 1989).] Connolley has authored and co-authored many articles in the field of climatological research. It is his view that there is a consensus in the scientific community about climate change topics such as global warming, and that the various reports from the Intergovernmental Panel on Climate Change (IPCC) summarise this consensus. [ [http://www.realclimate.org/index.php?p=86 "Just what is this Consensus anyway?", 22 December 2004 (Real Climate.org)] ]

Connolley served as a parish councillor in the village of Coton (near Cambridge, England) until May 2007. [ [http://web.archive.org/web/20070829055218/http://www.cotonpc.org.uk/ Internet Archive copy of Coton Parish Website] ] He stood as a Green Party candidate for either South Cambridgeshire District Council or Cambridgeshire County Council every year from 2001 to 2005.

cientific work

Connolley has long had an interest in confronting the notion that "all scientists were predicting an ice age in the 1970s" (known as global cooling). [ [http://www.realclimate.org/index.php?p=94 The global cooling myth] ] [cite web|title=Was an imminent Ice Age predicted in the '70's? No|author=William M. Connolley|url=http://www.wmconnolley.org.uk/sci/iceage/|accessdate=2007-12-16|year=2005] Connolley maintains a webpage analysing papers relevant to this issue.

One of Connolley's principal research interests was sea ice, its observations and modelling, in global climate models (GCM), especially the HadCM3 GCM. Around Antarctica, direct observations of sea ice are sparse, and even the most easily observable quantity, ice fraction, is not directly available; satellite Special Sensor Microwave/Imager (SSMI) based observations are used instead. However, different algorithms produce somewhat different results, sufficiently so that verification of GCM output becomes difficult. Hence Connolley has studied the validation of the SSMI products against more direct observations from upward looking sonar observations in the Weddell Sea area. In his investigation, the results indicate the Bootstrap product appears to "fit better" than the NASA Team product, and it is believed by Connolley that the GCM results are more realistic than previous results.

Wikipedia activity

In 2005, the scientific journal "Nature" wrote a comparison of the relative reliability of Wikipedia and the print-based "Encyclopedia Britannica". [cite journal|author=Jim Giles|journal=Nature|title=Special Report: Internet encyclopaedias go head to head|year=2005|volume=438|pages=900–901|doi=10.1038/438900a] In the "Nature" article, Connolley was discussed as an example of an expert who regularly contributes to Wikipedia. [cite journal|author=Jim Giles|journal=Nature|title=Challenges of Being a Wikipedian|year=2005|volume=438|pages=900–901|doi=10.1038/438900a]

A July 2006 "New Yorker" explains that Connolley briefly became "a victim of an edit war over the entry on global warming," in which a skeptic repeatedly watered down the article's explanation of the greenhouse effect. The skeptic later brought the case before Wikipedia's arbitration committee, insisting that Connolley was pushing his own point of view into the article by removing points of view with which he disagreed. The arbitration committee eventually placed Connolley on parole, although this was later revoked and Connolley went on to become an administrator. Jimbo Wales cited the sanctions against Connolley as a failure of the system. The article explains that Connolley believes "that Wikipedia 'gives no privilege to those who know what they’re talking about'".cite news|first=Stacy|last=Schiff|title=Know It All: Can Wikipedia conquer expertise?|url=http://www.newyorker.com/fact/content/articles/060731fa_fact|work=The New Yorker|date=2006-07-31| accessdate=2007-01-05]

An October 2006 "Nature" article on the "rival" Citizendium project quotes Connolley as saying that "some scientists have become frustrated with Wikipedia" but adds that he believes that "conflict can sometimes result in better articles."
