Esforços de síntese de evidências vêm apontando para o avanço das formas organizadas de desinformação e negação do conhecimento científico sobre a mudança climática global. Em vários países do mundo, há um forte debate sobre a difusão dessas narrativas no ambiente online e seus impactos políticos, sociais e econômicos. Neste trabalho, realizamos uma revisão de escopo aplicada às bases Web of Science e Scopus, a fim de mapear como a literatura acadêmica internacional vem descrevendo as relações entre o negacionismo da ciência sobre mudanças climáticas e o uso de campanhas de desinformação no século XXI, assim como as possíveis lacunas e apontamentos desses estudos para a agenda de pesquisas. Em todos os tipos de mídias estudados nos 31 artigos selecionados, foi identificada uma predominância de discursos contrários ao consenso científico sobre o tema, alavancada por campanhas de desinformação organizadas, inclusive, por atores governamentais. Observamos um crescimento significativo do campo nos últimos anos, assim como transformações estratégicas nas comunicações negacionistas tendendo a uma disputa maior da opinião pública sobre a ciência

The proliferation of conspiracy theories surrounding George Soros and the ‘Globalist invasion’ had been concentrated primarily in Eastern Europe, Russia and the United States. However, since Jair Bolsonaro’s presidential victory in Brazil, Soros has become a target of the far-right in the country. On Soros’ 90th Birthday in August 2020, the right-wing group ‘Movement for Conservative Brazil’ (Movimento Brasil Conservador – MBC) launched a campaign called ‘International Day Against George Soros’, aiming to attack the billionaire’s reputation. The purpose of this paper is to investigate how this campaign worked across online platforms as a strategy to popularize the Globalism conspiracy theory in the biggest Latin American country. We aim (1) to map the dynamics of disinformation dissemination across chat apps using hyperlink analysis; and (2) to interpret conspiratorial narratives about George Soros shared on chat apps during the month of his 90th birthday. We collected messages mentioning the anti-Soros campaign in WhatsApp and Telegram public groups and channels to extract hyperlinks and domains. These websites were manually categorized in an effort to analyze which conspiracy theories about George Soros are being disseminated on chat apps in Brazil. Our results suggest an increasing cross-platform dissemination of narratives attacking Soros. This case study illustrates how the rise of a transnationally networked political right has been accompanied by an emerging alternative digital communication infrastructure through which conspiracy theories circulate.

Social bots are automated agents programmed to act on social media impersonating human behaviour to influence discussions online. This paper aims to contribute to the discussion of how bots can endanger online communication and alter information flows. We resorted to a mixed-method approach based on grounded theory and observational techniques in order to investigate the bots’ activities online during the 2016 municipal elections in Rio de Janeiro. We collected related content on Twitter in this period and detected 3,101 bots. This sample was classified in three categories based on tweeting content: user-generated bot, media spambot, and political bot. Our findings indicate that, although bots work for different political and social purposes, their computational nature claims into service of dominant social groups and economical elites. We conclude that computational propaganda is building a dangerous scenario of widespread automation in which different kinds of algorithms bias social media conversation.
