This article investigates whether climate skeptics\u2019 claims are admitted in Wikipedia, the encyclopedia that anyone can edit. We carried a case study involving 93 global warming\u2013related articles in Portuguese Wikipedia, analyzing their revision history from the perspective of Actor\u2013Network Theory in two moments (2014 and 2017). We found that while \u201cAquecimento global\u201d and other highly accessed articles support thoroughly anthropogenic climate change, it was not the case until 2012, long after the question had been settled by scientists; claims disputing the human influence on the climate remain in some articles. The enforcement of Wikipedia policies was crucial to ensure that anthropogenic climate change would prevail and that the collaborative encyclopedia would become a spokesperson for climate science.<\/jats:p>","DOI":"10.1177\/1461444819838227","type":"journal-article","created":{"date-parts":[[2019,4,3]],"date-time":"2019-04-03T07:02:14Z","timestamp":1554274934000},"page":"2261-2282","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["How anthropogenic climate change prevailed: A case study of controversies around global warming on Portuguese Wikipedia"],"prefix":"10.1177","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2156-0440","authenticated-orcid":false,"given":"Bernardo","family":"Esteves Gon\u00e7alves da Costa","sequence":"first","affiliation":[{"name":"Universidade Federal do Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henrique Luiz","family":"Cukierman","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio de Janeiro, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,4,3]]},"reference":[{"key":"bibr1-1461444819838227","volume-title":"Climate Change 2014.
