Wikipedia is the most popular source of written information in the world. It is the third most popular non-search engine site on the web, bested only by Facebook and YouTube. In other words, it can be a potent ideological force.
And it has been. The site's administrators recently banned 16 users from editing any article related to global climate change. One user, William Connolley - also an active member of the UK Green Party - had been editing misinformation and propaganda into Wikipedia articles since 2003.
Climate alarmists have put enormous pressure on the western media to suppress knowledge of facts inconvenient to their scientific arguments using a variety of methods to supress dissenting opinion.
Besides threatening journalists, promoting the use of Nazi-esque insults like the word "deniers," and bullying scientists who publish research papers critical of their near-religious beliefs, alarmists have taken to the web with aplomb, most famously exposed in the ongoing "ClimateGate" scandal.
Engaging in politicized science via email isn't the only cyber activity that left-enviro activists engage in however. Wikipedia is also a favorite target, particularly for a British global warming activist named William Connolley who seems to have made it his life's mission to censor climate realists in the online encyclopedia.
