Wikipedia is supposed to be the on-line encyclopedia for everyone, but what it has become is something entirely different: an early and illustrative warning of the collapse from informed social networking to propaganda. If you just enter “global warming” in google the first result you get points to the Wikipedia entry Connolley controls - and if you just wanted a two minute briefing on the subject you’d never know that the article is utterly and relentlessly dishonest.
