Amazon-related messages on Telegram surged after 2019, often outpacing traditional media in volume and intensity, especially during crises like forest fires and international summits.  Polarization and Securitization Shape Amazon Narratives Telegram discourse is highly polarized, with competing narratives from a diversity of actors. Topics such as illegal mining, military operations, and sovereignty dominate, reflecting a securitized framing of the Amazon that often overshadows ecological concerns.  Disinformation Undermines Climate Action The spread of misinformation—especially denialist and conspiratorial content—on Telegram distorts public understanding of Amazon issues. This undermines trust in science, delays policy responses, and reinforces harmful narratives that serve vested interests.  Digital Virality Amplifies Strategic Messaging Coordinated cross-posting and forwarding behaviors allow actors to rapidly disseminate content across large audiences. This infrastructure enables both genuine mobilization and manipulative campaigns, making Telegram a powerful tool for shaping public opinion on environmental governance.  Policy Must Address Both Ecological and Informational Integrity Protecting the Amazon requires not only physical conservation efforts but also strategies to counter digital disinformation. Strengthening climate literacy, public dialogue, and platform governance is essential to prevent negative social tipping points and support evidence-based environmental policies. Carneiro & Tucci The Amazon Biome in Messages 3 1. Introduction The Amazon biome contains the world’s largest and most biodiverse rainforest. The enormous green spread on the world map constitutes a complex living system that sustains planetary life, harboring about one in ten of all known species within its boundaries (Pilcher, 2023). It covers roughly seven million square kilometers, an area similar to Australia (Bryce, 2023), and, spanning nine nations, provides habitat to around thirty million people, including more than 350 Indigenous ethnic groups (Pilcher, 2023). This diverse combination of life highlights both the forest’s ecological value and cultural significance. The Amazon also acts as a planetary engine. Its vast carbon stock – about 150 billion metric tons – is equivalent to more than ten years of global fossil‑fuel emissions (Asner et al., 2010). Roughly half of this carbon is stored in soils (Fauset et al., 2015), and the rest in more than 16 thousand tree species (ter Steege et al., 2013). By locking away about one‑fifth of all carbon captured by vegetation worldwide, the forest regulates atmospheric chemistry, thereby reducing the pace of global warming (Fauset et al., 2015). The rainforest's “hydrological engine” recycles water vapor between five and six times, creating its own rain and influencing rainfall patterns across South America (Lovejoy & Nobre, 2019). These processes sustain agriculture in distant regions, through so‑called “flying rivers” of atmospheric moisture, and stabilize regional temperatures (Ferrante et al., 2023). Despite its importance, the region faces severe threats from human activities and global warming. Deforestation has removed almost a fifth of the forest in the last forty years; more specifically, scientific assessments estimate that about 17% of tree cover has been lost since 1970 (Bryce, 2023; Lovejoy & Nobre, 2019), and by mid‑2025, roughly 18% had been cleared (Watts, 2025). These losses are driven by agribusiness, mining, and land speculation (B. Brito et al., 2019; Lapola et al., 2023), often through fire‑clearing methods that transform stored carbon into carbon dioxide. As trees are felled and burned, parts of the forest have already become net emitters of CO₂ (B. Brito et al., 2019). The cumulative impacts of deforestation and a warming atmosphere threaten to push the Amazon beyond a tipping point (Lovejoy & Nobre, 2019; Watts, 2025). Earth systems scientist Carlos Nobre warns that losing just 20–25 % of pre‑deforestation tree cover could irreversibly transform the rainforest into a degraded savannah (Watts, 2025). The ongoing trend of longer and drier dry seasons is already evident; between the 1970s and the present, the southern Amazon’s dry season has lengthened by several weeks, and the region has experienced four severe droughts in two decades (Watts, 2025). Should deforestation continue unrestrained, local rainfall could decrease by up to 30% and regional temperatures would rise by several degrees (Bryce, 2023). The resulting release of 200–250 billion tonnes of CO₂ would effectively render the Paris Agreement goal of limiting warming to 1.5 °C unattainable (Da Silva Junior et al., 2020; Watts, 2025). Beyond climate, this ecological collapse would jeopardise South American agriculture (Lovejoy & Nobre, 2019; Watts, 2025), intensify fire risk (Da Silva Junior et al., 2020; Le Page et al., 2017), and increase the likelihood of infectious disease spillovers (Ellwanger et al., 2020), while also compromising local water security, since life systems in the Amazon critically and directly depend on water — not only for climate balance, but also for transportation, subsistence, and cultural integrity (Börner; Scholl, 2009). Carneiro & Tucci The Amazon Biome in Messages 4 Recent observations further indicate that the frequency and intensity of extreme precipitation events — both heavy rainfall and prolonged droughts — have significantly increased in the Amazon basin, which further intensifies the ecological and social risks associated with deforestation and forest degradation (Cerón et al., 2024). The risks posed by unchecked deforestation and climate change in the Amazon are compounded by a less visible, but equally profound, threat: the distortion of climate information in digital spaces. Climate misinformation and disinformation hinder the collective response needed to address environmental crises. Research on social media platforms shows that content linking to unreliable sources garners significantly higher engagement than content linking to reliable sources (Edelson et al., 2021; Vosoughi et al., 2018). Social media algorithms encourage users to select information that aligns with their online behavior and pre-existing beliefs (Reviglio & Agosti, 2020; Zollo et al., 2015), thereby fostering echo chambers and ideological segregation (Guo et al., 2020). Bots and trolls further amplify false narratives, undermining public understanding of climate science (Carrington, 2025). Widespread climate misinformation threatens collective responses by eroding trust in scientific evidence, derailing evidence-based policy debate, and polarizing communities (Lewandowsky et al., 2017; Treen et al., 2020). A 2025 study by the International Panel on the Information Environment (IPIE) found that climate action is being obstructed by false and misleading information originating from a range of actors, including fossil‑fuel lobbies, political groups, and certain nation-states (Elbeyi et al., 2025). Such dynamics reflect a broader crisis of information integrity: effective climate policy depends on a well‑informed public, yet disinformation distorts perceptions (Hameleers, 2023), delays action (Lamb et al., 2020), and erodes trust in science (Gundersen et al., 2022; Reed et al., 2021). In response to the growing threat of climate change misinformation, in November 2024, the Brazilian government, the United Nations Secretariat (UN) and the UN Educational, Scientific and Cultural Organization (UNESCO), launched the Global Initiative for Information Integrity on Climate Change (SECOM, 2024; UNESCO, 2024). This international alliance seeks to confront the spread of misleading narratives by fostering rigorous, evidence-based research, advancing transparency in climate communication, and strengthening policy frameworks at both national and transnational levels. In this context, the objective of our research is to characterize and analyze how debates about the Amazon biome are framed and disseminated across Portuguese-language public Telegram channels. As researchers at CGIAR Climate Security, led by the Alliance of Bioversity International and CIAT, we position this study within CGIAR's research-for-development mission to advance science and innovations that enhance the resilience and sustainability of food, land, and water systems. By investigating how climate (dis)information circulates in digital spaces such as Telegram and how frames tied to governance, sovereignty, risk, and enforcement are amplified, our work equips decision-makers with actionable insights to design targeted interventions. This includes strategies Carneiro & Tucci The Amazon Biome in Messages 5 to counter disinformation that undermines climate action and adaptation planning in the Brazilian Amazon and, by extension, in other contexts served by CGIAR. The Alliance of Bioversity International and CIAT also participates in the Brazil Chapter of the Global Initiative for Information Integrity on Climate Change, underscoring our institutional commitment to safeguarding climate information ecosystems. This working paper operationalizes that commitment by relying on digital methods (Rogers, 2013, 2024) and employing a reproducible pipeline to map discourse dynamics, identify influential actors, and surface policy-relevant narratives that impact climate action. Within this global framework, we explore a central research question: What narratives and network structures shape the circulation of Amazon Biome-related messages on public Portuguese- language Telegram channels? This study examines these informational dynamics through the lens of Telegram, a hybrid platform that has gained significant influence in Brazil's digital public sphere (Cavalini et al., 2023; M. Júnior et al., 2022; Tucci, 2023; Tucci & Gouveia, 2025). While the app enables rapid message dissemination and group mobilization, its encrypted architecture and limited content moderation can also enable the proliferation of unverified information and facilitate ideological coordination (Rogers, 2020; Urman & Katz, 2022). Through exploratory analysis, our findings aim to inform institutional responses, platform governance debates, and public policy processes addressing climate-related disinformation. The remainder of the working paper is organized as follows. Section 2 provides background on three interlinked areas: (2.1) how the Amazon biome is represented in Brazilian media and political discourse and (2.2) Telegram’s role within Brazil’s media ecosystem and its use in political communication. Section 3 outlines our data and methods, detailing the creation of our Telegram dataset (3.1), the data processing pipeline (3.2), and the study design and analytical workflow (3.3). Section 4 presents the results and the discussion: we first provide a dataset overview (4.1), then discuss topic modelling results (4.2), and network analysis. Finally, we reflect on the broader implications of our findings for the intersection of public policy, digital communication, and Amazon narratives, before concluding with suggestions for future research. Carneiro & Tucci The Amazon Biome in Messages 6 2. Background 2.1 Representations of the Amazon biome in the Brazilian digital ecosystem and political discourse The Amazon rainforest holds a central place in Brazil’s media and political discourse, often framed in the context of conflicting interests between environmental protection, economic development and national sovereignty (Bidone & Kovacic, 2018; Zhouri, 2010). In the digital sphere, these debates have intensified, with social platforms amplifying both genuine concern and disinformation. While environmental scientists and activists highlight the Amazon biome’s critical role in biodiversity conservation and climate stability, warning of increasing ecological crises (Skill et al., 2021), voices aligned with agribusiness and resource exploitation sometimes dismiss or downplay these issues (Ferrante & Fearnside, 2019) – through forms of denialism, obstruction and greenwashing – and frame international concerns as attacks on Brazilian sovereignty (Salles et al., 2023). During the Bolsonaro administration (2019-2022), official data and scientific evidence concerning the environment were systematically questioned, distorted, and disregarded (Hallal, 2022). His government actively discredited deforestation data provided by the National Institute for Space Research (INPE), which monitors Amazon forest loss. In 2019, Bolsonaro publicly dismissed INPE’s satellite data that showed a sharp increase in deforestation, labeling it as false and damaging to Brazil’s image (Deutsch & Fletcher, 2022). This dispute culminated in the forced resignation of INPE’s director (Barrucho, 2019), Ricardo Galvão, following his defense of the agency’s data integrity. The government’s dismissal of scientific evidence was part of a broader pattern of undermining environmental institutions and the scientific community to advance economic interests (Davis et al., 2020; Fuchs et al., 2023). These actions severely weakened environmental governance and compromised Brazil’s credibility in global climate discussions. Despite government attacks, INPE’s monitoring systems continued to reveal alarming deforestation trends during Bolsonaro’s term, with deforestation rates significantly rising (Da Silva Junior et al., 2020). The political attempts to discredit and control environmental data demonstrated the administration’s prioritization of economic expansion and clientelism over conservation and transparency, further complicating efforts to address environmental degradation in the Amazon region. For example, during the 2019 surge in Amazon forest fires, Bolsonaro’s administration rolled back forest protections and cultivated an online narrative blaming non-governmental organizations (NGOs) for the fires (Lyndon et al., 2022; Skill et al., 2021; Watts, 2019). The president formally asserted to the UN that Brazil has been subjected to a “brutal disinformation campaign” concerning the Amazon, insinuating that vested interests and “unpatriotic” actors were engaged in efforts to undermine his administration (United Nations General Assembly, 2020). This rhetoric resonated with a segment of the public (Lyndon et al., 2022), reinforcing longstanding conspiracy theories that foreign powers and their local allies want to internationalize the Amazon for economic gain (Zhouri, Carneiro & Tucci The Amazon Biome in Messages 7 2010). Such claims were widely propagated online despite a lack of evidence, and scientific recognition that land tenure structure and cattle ranching are central drivers of deforestation (Díaz Baca et al., 2024). Observers documented a surge of misleading content in 2019 as global attention turned to the Amazon fires (Barsotti, 2023; Chokshi, 2019; Lyndon et al., 2022; Mooney, 2020). Bolsonaro government allies on social media spread unsubstantiated accusations, such as alleging that environmental NGOs had started the fires to make the government look bad (Uribe, 2019; Watts, 2019) or that the Chico Mendes Institute for Biodiversity Conservation, ICMBio, was responsible for fire ignitions, even when actors spreading these narratives were themselves caught committing environmental crimes (Matias, 2019). These examples illustrate how disinformation has been used as a political tool to mislead facts and shift blame around Amazonian deforestation. Studies of false Amazon-related news have found a consistent pattern: many rumors and fake claims adhere to denialist thinking and seek to downplay the severity of the Amazon biome’s degradation (Fachin et al., 2024; Salles et al., 2023) to serve the interests of those who wish to continue profiting from forest exploitation. Nevertheless, the Brazilian digital information ecosystem also hosts powerful narratives in defense of the Amazon. Viral campaigns and hashtags (e.g., #PrayforAmazonas) have mobilized public opinion domestically and worldwide, especially during high-profile crises like the 2019 fires (Skill et al., 2021). Social media enabled indigenous leaders, environmental NGOs, and concerned citizens to share on-the-ground images of burning forests and to demand action, forcing Amazon issues onto the policy agenda. However, these genuine expressions of concern often encountered a wall of counter-messaging. Researchers note that socio-environmental disinformation in Brazil frequently takes two forms: either it reinforces prejudices and hate speech, for instance, portraying indigenous people and environmentalists as obstacles to progress, or it is deployed strategically as a smokescreen to distract from real problems (Salles et al., 2023). In June 2022, following the assassinations of indigenist Bruno Pereira and journalist Dom Phillips in the Amazon (Bonaldo et al., 2022; Nicas et al., 2022), a disinformation smokescreen strategy was deployed. As public outrage and scrutiny of criminal activities in the rainforest intensified, a fantastical conspiracy theory about a “lost city” called Ratanabá rapidly gained traction on Brazilian social media (Biernath, 2022; R. Júnior & Mesquita, 2022). The Ratanabá hoax – claiming an ancient extraterrestrial city lay hidden under the jungle – was amplified by pro-Bolsonaro influencers and even the government's former culture secretary (Lima, 2022), in an attempt to divert attention from real-world violence and impunity in the region. This incident highlights how easily a sensational falsehood can overshadow urgent issues online, illustrating the volatile mix of emotion, myth, and agenda-driven messaging that characterizes digital discourses. Empirical studies and monitoring projects have begun to map the dynamics of Amazon-related communication. A 2023 report by the Brazilian collective Intervozes (2023) identified dozens of public figures and digital outlets that consistently spread misinformation about the biome. Their analysis of 70 social media profiles (between March and September 2022) revealed that many false Carneiro & Tucci The Amazon Biome in Messages 8 claims about the Amazon originate in conservative activist circles, politicians’ pages, or partisan alternative-media sites. Common themes include promoting stereotypes (e.g., portraying the Amazon as an empty land for the taking), inciting hostility toward environmental defenders, and denying scientific facts about deforestation and climate change. According to Intervozes’ coordinator Viviane Tavares, these talking points either fuel hate and prejudice or are used “strategically as smokescreens in the service of agribusiness interests” (Ferreira, 2023). In other words, incendiary cultural issues or outright hoaxes are injected into the conversation to distract from illicit logging, land-grabs, and rollbacks of environmental policy. As the current environment minister, Marina Silva, argued in an interview prior to taking office, digital disinformation comes in with full force to maintain a deeply unequal economic model that drives forest destruction (Lazzeri, 2022). Silva – herself a frequent target of online attacks – affirms that fake news and climate denial are wielded to discredit science and to paint environmentalists as threats to national sovereignty (Lazzeri, 2022). One recurring false narrative accuses her of wanting to “internationalize” or even sell the Amazon to foreigners, echoing a trope used against many conservation efforts (Lazzeri, 2022). By spreading such false claims, powerful interests seek to undermine public support for pro-conservation policies. Indeed, Silva noted that a “parallel fictional narrative” had taken hold in some online communities – one in which “Brazil is not suffering from wildfires or deforestation, despite the data indicating the extreme opposite” (Lazzeri, 2022). Discussions of the Amazon on Brazilian digital media are polarized and passionate. The rainforest has become a symbolic battleground in the culture wars: it is a rallying cause for environmental activism and an object of nationalist fervor and misinformation. For public policy, this means any effort to protect the Amazon must engage with physical challenges on the ground and with narrative and information challenges online. In the following section, we examine one of the key digital arenas where these battles play out: Telegram, an increasingly influential platform in Brazil’s digital ecosystem 2.2. Telegram and its role in Brazilian digital ecosystem and political communication Telegram has emerged as a conduit for political communication and media content in Brazil (Benevenuto & Melo, 2024; Cavalini et al., 2023; M. Júnior et al., 2022; Tucci & Gouveia, 2025). Alongside WhatsApp, Telegram stands out as a hybrid social platform with messaging features that are deeply integrated into daily life in Brazil (Benevenuto & Melo, 2024), thanks to affordable mobile data plans and the apps’ versatile group and channel features (Tucci, 2023; Tucci & Gouveia, 2025). By the late 2010s, essentially “everyone with a mobile phone” in Brazil was using WhatsApp (Saboia, 2016) – or increasingly, Telegram (Statista Research Department, 2023) – for everything from family chats to education and community forums, as well as commercial purposes. Telegram distinguished itself by offering public channels and super-groups that can gather massive audiences, far beyond WhatsApp’s group size limits. While WhatsApp capped group chats (initially at 256, currently at 1,024 members) and restricted message forwarding to curb virality (Greenspan, Carneiro & Tucci The Amazon Biome in Messages 9 2019), Telegram allowed groups of up to 200,000 users (Telegram, n.d.), enabling a single message to be broadcast to vast numbers of people. This design made Telegram especially attractive for activists, influencers, and political operatives seeking to amplify their message without the constraints of traditional social media platforms (Rogers, 2020). Telegram’s permissive environment allows the radicalization of some communities. For instance, the Islamic State of Iraq and Sham (ISIS) made use of the app's affordances to catalyze terrorist mobilization (Shehabat et al., 2017), while Telegram also hosts groups and channels that function as incubators for conspiracy theories – from QAnon-style fantasies (Urman & Katz, 2022) to Amazon-related hoaxes (Massarani et al., 2024). The rise of Telegram in Brazil is closely tied to the country’s recent political turbulence. During the 2018 presidential election, campaign strategists were already exploring Telegram as a tool for mass messaging and mobilization (Benevenuto & Melo, 2024), although WhatsApp was the dominant force in that election’s misinformation outbreaks (Benevenuto & Melo, 2024; Santini et al., 2021). In 2021, political events in the U.S. (Fung, 2021), created a temporary rupture in the relationship between mainstream digital platforms and political actors associated with extremist discourses. As mainstream platforms such as Twitter, Facebook, and YouTube intensified content moderation measures, many of these actors began to migrate to less regulated environments, with Telegram emerging as a prominent alternative (Rogers, 2020). Far-right political actors increasingly relied on Telegram as a mass-communication channel, particularly as platforms like Facebook, Twitter, and WhatsApp began complying with Brazilian court orders to remove accounts spreading false information (Brito & Paraguassu, 2022). Numerous conservative public channels and groups flourished, forming an ecosystem of alternative content where members share memes, videos, and calls to action (Tucci, 2023; Tucci & Gouveia, 2025). Researchers mapping these networks found that they functioned as a dense “information disorder” system circulating aligned content across groups (Cavalini et al., 2023). By late 2022, Brazilian Telegram chats called for mass demonstrations to overturn the results of the presidential elections that re-elected Luiz Inácio “Lula” da Silva. This culminated in the January 8, 2023, attacks in Brasília (often likened to the U.S. Capitol attack), when encrypted messaging groups were used to organize the anti-democratic invasion of government buildings (Fonseca, 2023; Nascimento et al., 2022; Prazeres, 2023). In the lead-up, some Telegram channels openly promoted the event, illustrating how the platform can accelerate extremist coordination. Content that might remain fringe on open social networks can rapidly circulate in Telegram loops, where users forward messages across dozens of groups with a few clicks. This virality under encryption poses a challenge: harmful rumors or propaganda can spread widely through the Telegram sphere before authorities or fact-checkers notice it. Telegram’s prominence has not gone unnoticed by institutions. In fact, Brazil became an example of how governments might respond to an influential but unregulated social platform. In March 2022, amidst concerns about election misinformation, the Brazilian Supreme Court suspended Telegram nationwide after it repeatedly ignored court orders to block certain accounts spreading fake news Carneiro & Tucci The Amazon Biome in Messages 10 (Brito & Paraguassu, 2022). The ban made Telegram’s CEO apologize and comply with Brazilian judiciary demands (Nicas & Spigariol, 2022). Subsequently, the Superior Electoral Court (TSE) implemented a program to protect information integrity during the 2022 elections, establishing partnerships with platforms and civil society (Rubio & Monteiro, 2023). Researchers who monitored public Telegram groups helped expose networks of misleading content, a proactive measure to protect the electoral process and democracy in Brazil (Benevenuto & Melo, 2024). Despite these efforts, tension between Telegram and Brazilian authorities continued. In April 2023, as Brazil’s Congress debated a landmark bill to regulate digital platforms (known as the Fake News bill), Telegram inserted itself into the political fray by sending an unsolicited message to all its Brazilian users, warning that the law would lead to censorship (Tucci, 2023). This provocative move – essentially lobbying its user base against government policy – prompted another Supreme Court order and fines against Telegram for spreading misleading information about the bill (STF, 2023). The incident highlighted how digital platforms can directly leverage their power to influence public opinion and policy. By 2025, estimates suggested that roughly 20–25 million Brazilians actively use Telegram (around 38% of internet users), making Brazil one of the app’s largest markets worldwide (Guan, 2025). Such deep penetration, combined with Telegram’s role in high-stakes political events, firmly establishes it as a critical element of Brazil’s digital ecosystem. Telegram in Brazil is one of the many examples of the double-edged nature of digital media’s impact on society. On one hand, it has enabled communities to form outside the purview of traditional gatekeepers, giving voice to groups that feel excluded by mainstream media. On the other hand, its unmoderated interconnected spaces have incubated hate speech, conspiracy theories, and organized attacks on democratic institutions. Any analysis of Amazon issues on Brazilian Telegram channels must therefore consider this broader context: the platform as a conduit for passionate, unfiltered discourse, but also a breeding ground for informational chaos. The complex discourse surrounding the Amazon rainforest – which intertwines nationalism, environmental urgency, and global scrutiny – integrates seamlessly into Telegram’s dynamic content ecosystem, characterized by highly charged and rapidly evolving narratives. Carneiro & Tucci The Amazon Biome in Messages 11 3. Data and Methods Applying digital methods (Rogers, 2013, 2024) to Telegram means following the medium – treating channels, forwards, mentions, and t.me link ecologies as native research signals – and foregrounding its structural biases. Telegram's broadcast channels with unlimited audiences, low- friction forwarding, and semi-private group dynamics favor rapid recirculation, admin-centric authority, and porous public/private boundaries (Peeters & Willaert, 2022; Tucci & Gouveia, 2025). Our analytical approach operationalizes these platform-specific affordances through topic framings, forwarding patterns, channel-influence metrics, virality indicators, and cross-platform circulation tracing, rather than importing external assumptions. 3.1. Building the dataset Initially, a dataset containing 964 public Portuguese-language Telegram channels was aggregated from the Telemetr.io (n.d.) repository, comprising 567 Politics and 397 News & Media channels (Tucci, 2025a). The channels were collected by querying the repository using combined language and category filters. Telemetr.io provides up to 10 pages of results per query, with 100 channels per page ranked by audience size, allowing retrieval of a maximum of 1,000 channels per language- category combination—specifically those with the largest audiences in each category. The selected collection of channels presents considerable relevance for our study due to its large audience reach, as indicated by its ranking on the Telemetr.io platform. Additionally, it includes categories that systematically address political debates, allowing for comprehensive monitoring of channels that play a significant role in shaping public opinion. Starting from the list of Portuguese-language channels, we uploaded it to TeleCatch (Ruscica et al., 2025) and accessed the content and metadata of all chats. Aiming to capture debates about the Amazon rainforest, we applied a content filter by combining the terms “Amazon” and “Amazonian” in Portuguese (amazonia/amazônia and amazonica/amazônica) and downloaded the resulting messages. No date filter was used. 3.2. Data processing We employed Telegram Analytics (Tucci, 2025b), an R-based pipeline for analyzing Telegram datasets, to process 39,333 Amazon-related messages extracted from 605 channels. The tool was used to run popularity analysis, temporal analysis, network analysis, and topic modeling. We applied Latent Dirichlet Allocation (LDA) topic modeling to explore thematic structures in the Telegram dataset. Messages were pre-processed by removing punctuation, numbers, and tokens shorter than three characters. Stopwords in Portuguese, English, and Spanish were excluded, as well as the filtering terms. A Document–Term Matrix was built at the message level and used as input to the LDA model. The number of topics was set to eight, producing probabilistic clusters of co- occurring terms. For interpretation, we extracted the most representative words for each topic and Carneiro & Tucci The Amazon Biome in Messages 12 generated visualizations such as word clouds. Each message was then assigned to its most likely dominant topic. This approach has limitations: given the long timespan of the dataset, discursive shifts may collapse into single topics, and short Telegram posts often lack enough context for stable modeling. Nevertheless, topic modeling provides a useful exploratory lens to identify recurring themes and map discursive fields across the corpus. To investigate the linkage between channels and topics over time, a network was constructed using Gephi software (Bastian et al., 2009). This bipartite network includes two distinct types of nodes: the monitored Telegram channels and the message topics derived from LDA analysis. Edges connect each channel to its dominant message topics based on the content it broadcasted. By incorporating the date of each message, a dynamic temporal network was created, enabling visualization and analysis of how channel-topic associations evolved from 2015 to 2025. This approach facilitated the examination of shifting discourse patterns and thematic prominence within the Telegram ecosystem over this period. 3.3. Study design and analytical workflow To explore our research question, we need to identify discursive frames (narratives) and network structures of Amazon biome-related messages circulating within the sample of the Telegram sphere we observed. Our methodology focuses on two core elements: (i) tracing narratives dissemination by investigating infrastructural dynamics and channel connections that influence political discourse, and (ii) examining how Telegram's technical features and usage patterns interact to shape user perceptions and platform functionality. This approach allows us to understand how the platform's affordances directly influence observed discourse patterns around environmental issues. Our study incorporated a timeline annotation strategy (Basnet et al., 2023; Bruns & Hanusch, 2017; Neumayer & Rossi, 2016), marking significant media-reported events to contextualize discursive shifts and network transformations within the observed period. Identified message topics were systematically analyzed using established methods for topic modeling (Tang et al., 2014) and discourse mapping in digital environments (Venâncio et al., 2024; Willaert, 2022). Furthermore, the relationship between channels and topics was mapped through a bipartite network approach, following best practices in digital network analysis that account for platform-specific affordances and structural properties (Peeters & Willaert, 2022; Rogers, 2024; Venturini & Latour, 2010). This integrated methodology enabled a dynamic, temporal exploration of how influential actors and thematic fields evolved in response to political, media, and platform-based events, yielding insights into the evolving landscape of Amazon Rainforest communication on Telegram. Carneiro & Tucci The Amazon Biome in Messages 13 4. Results and Discussion 4.1. The temporal trajectory of Amazon narratives across Telegram We analyzed 39,333 messages mentioning the Amazon biome shared by 605 channels, posted between December 2015 and May 2025 (when the dataset was created). Messages generated almost 60 million views (59,464,010 total); 23,110 contained media; 2,017 were forwards; 283 were replies. Figure 1 shows the daily message volume evolution. The activity starts near zero, rises steadily from late 2019, and maintains a higher baseline after 2021, with intermittent sharp spikes. Variability increases through 2024–2025, indicating more intense and bursty conversations about the Amazon. The highest message peak was recorded on March 26, 2025 (293 messages), and corresponds to the recirculation of links from previous years that praised the Army for various actions — such as Operation Tucumã, heroic rescues, partnerships to protect Yanomami lands, support for ICMBio, strategic transportation, and the defense of national security in the Amazon. Although originating from different dates, all this content was published on that specific day. Figure 1. Daily Amazon-related message volume on Portuguese-language Telegram channels, 2015 to May 2025. Blue bars on the chart show the number of messages per day across 605 public channels; the orange curve is a smoothed trend line summarizing long-run change. Source: Telegram Analytics (Tucci, 2025b) In 2023, notable surges on August 7, 8, and 9 (132, 199, and 148 messages) correspond to the Amazon Cooperation Treaty Organization Summit in Belém, illustrating the impact of multilateral environmental diplomacy on public discourse (Watson & Christy Cooney, 2023). The May 20, 2022 peak (155 messages) followed Elon Musk's visit to Brazil, when he and Bolsonaro discussed expanding satellite internet coverage for remote areas including the Amazon, positioning technology Carneiro & Tucci The Amazon Biome in Messages 14 as vital for regional development (Stargardter et al., 2022). Peaks in June 2022, especially June 15 (150 messages), reflect intense news coverage and investigation into the murder of Bruno Pereira and Dom Phillips on June 5. In 2019 (Bonaldo et al., 2022; Nicas et al., 2022), concentrated activity occurred in late August amid a period of intense forest fires (Skill et al., 2021), with the highest daily volume (233 messages) on August 23, marking a turning point during Bolsonaro’s first year in office. To guide our analysis, we chose to verify Brazilian media coverage for mentions of 'amazônica' and 'amazonica'. The results of this search, conducted using Media Cloud (Roberts et al., 2021), are presented in Figure 2. An initial analysis reveals that Amazon-related topics apparently generate greater reverberations on Telegram than in traditional media outlets. The timelines in Figures 1 and 2 indicate coupling between major Amazon events in both media ecosystems and suggest Telegram increasingly serves as a high-frequency amplifier with its own internal rhythms. The news media data (Figure 2) reveals a compelling temporal narrative: Amazon- related debates gained significant momentum in 2018 and surged dramatically in 2019. This escalation in traditional media coverage occurred during the peak of international scrutiny over the Amazon fires (reaching a maximum of 1,169 stories on August 23, 2019), when environmental concerns reached unprecedented levels of global attention (Deutsch & Fletcher, 2022; Skill et al., 2021). What makes this timing particularly significant is that it coincided with Telegram's nascent stages of adoption in Brazil – the platform had yet to achieve the widespread penetration it would later experience in the 2020s (M. Júnior et al., 2022). Figure 2. Brazilian national news media daily coverage on the Amazon rainforest, attention over time, 2016 to May 2025. The chart shows the number of stories that match “Amazônia” or “Amazônica”. Source: Media Cloud - Brazilian National News Sources (167 news outlets) While news media sites were intensifying their Amazon coverage during Bolsonaro's early presidency, Telegram was simultaneously emerging as an alternative information space where different narratives could flourish with less oversight. The platform's subsequent growth into a major political communication tool (Benevenuto & Melo, 2024; Cavalini et al., 2023; M. Júnior et al., 2022; Tucci & Gouveia, 2025) suggests that the Amazon discourse we observe on Telegram today represents the evolution and transformation of 2018-2019 debates within a medium specifically designed for rapid and unfiltered information sharing. This convergence indicates that Telegram https://search.mediacloud.org/collections/34412257 Carneiro & Tucci The Amazon Biome in Messages 15 became a repository (Tucci & Gouveia, 2025) for Amazon-related discussions in traditional media that could now be amplified, reframed, and circulated through new networked pathways. 4.2. Uncovering Amazon rainforest narratives on Telegram through topic modeling Figure 3 presents the results of the topic modeling analysis, illustrating eight distinct clusters of Amazon-related narratives identified in Telegram messages: Platform Cross-Posting, Bolsonaro Government-centric Environmental Politics, Environmental Risk Monitoring, Diplomatic Agenda, Geopolitics & Sovereignty, Political News Cycle, Mainstream News Relay, and Securitized Amazon. Each topic is accompanied by a word cloud showing its most representative terms, along with a brief thematic description and message count. The matrix plot shows the yearly evolution of dominant discourse topics in Amazon-related messages on Portuguese-language Telegram channels from 2015 to 2025. Each colored square represents the volume of messages classified into one of eight topics. Larger squares indicate higher proportions of messages for a given topic in that year. The 'NA' column on the right captures messages that could not be classified into any thematic topic, frequently due to comprising only emojis or images. The “NA” (Not Assigned) category includes messages that, after data processing and cleaning, lack textual content – such as those containing only emojis, images, or other non-textual elements – which cannot be classified into any specific topic via the method employed. The presence of a substantial “NA” segment may indicate certain channels or actors primarily disseminate non-verbal content, such as memes, visual cues, or reaction emojis, instead of substantive discussion. Despite being unclassified by topic modeling, these “NA” messages still contribute to the overall discourse landscape. They can be analyzed for their frequency, source channels, and co-occurrence with textual posts to understand engagement styles or narrative strategies dominated by visual or symbolic communication. Including these messages in the dataset ensures a more accurate representation of the full range of communicative practices in the Amazon-related Telegram sphere.

Carneiro & Tucci The Amazon Biome in Messages 17 Evolution of the Amazon‑Related Discourse Network Over the past decade, the Amazon-related discourse network on Telegram transformed from a sparse relay system into a densely interconnected and ideologically segmented ecosystem (see Figure 4). In its early phase (2016), mainstream news outlets and URL aggregators were the primary hubs, reflecting Telegram’s limited reach and low editorial diversity. This began to change by 2018, as central nodes like ‘folhadespaulo’ (the channel for one of Brazil’s main traditional news outlets) and emerging political actors (e.g., politician ‘cirogomes’, or the Workers Party ‘PT’) signaled the expansion of participation and the growing politicization of the platform. By 2019, amid Bolsonaro’s presidency and the escalation of Amazon fires, polarization became pronounced. Pro-government and opposition channels proliferated, each amplifying distinct narrative clusters: Bolsonaro Government-centric Environmental Politics (topic 1), Securitized Amazon (topic 6), and Geopolitical Debates (topic 2). Fringe and conspiracy channels found footing in securitization frames, especially around illegal mining and border issues. In the years following, network complexity deepened, with 2021 and 2022 marked by the increased presence of military and influencer channels, and by highly coordinated messaging during key political and environmental events such as the Amazon Summit and electoral periods. The surge in cross-posting (topic 8) enabled local Amazonian agendas to be rapidly linked with national and international debates, evidenced by the rising prominence of regional media and institutional actors in the network. From 2023 onward, as Telegram reached nearly 40% penetration among Brazilian internet users (Kleina, 2025), the platform’s affordances enabled super-groups and coordinated cross-posting to dominate information flows. Regional and cultural outlets seamlessly integrated local developments into national discussions, making topic 8 the primary connective cluster. Despite the rise in rapid news relay (topics 3 & 7) during crises, political polarization endured, with government- aligned, independent, and indigenous channels competing for narrative space—especially around topics of risk monitoring (topic 4) and diplomatic agendas (topic 5). The network structure shows its transformation from a small group of channels that acted as news aggregators into a graph with polarized communities centered around security and political/partisan disputes, especially from 2019 onward. This transformation highlights how Telegram’s features — the ability to track forwarded messages, the perception of anonymity, and the merging of private messaging with discussion groups and broadcast channels — facilitate rapid recirculation and the formation of dense ties. Figure 4 indicates a core of news and media channels gradually surrounded by political and security clusters, with bridge nodes that translate news into calls to action — a pattern expected when we “follow the medium” and treat its native signals (forwards, mentions, t.me) as first-order data (Rogers, 2013, 2024). Recent literature on Telegram in Brazil also points to its role as a high- frequency amplifier and mobilization infrastructure, whose diffusion grew after 2018 (Cavalini et al., 2023; Júnior et al., 2022; Tucci & Gouveia, 2025).

Source: dynamic graph generated in Gephi (Bastian et al., 2009) using the OpenOrd layout (Martin et al., 2011). More detailed yearly visualizations and data in https://osf.io/7584k/. The tension observed between securitization and diplomacy (topics 5 and 6) reflects shifts in Amazon policies from the Bolsonaro cycle to the Lula cycle — that is, oscillations between operational/combat repertoires (illegal mining, border control, Armed Forces) and cooperation/climate repertoires (COP, summits, Belém), often mediated by bridge actors who translate framings from one field to another. This type of environment fosters disinformation: the https://osf.io/7584k/ Carneiro & Tucci The Amazon Biome in Messages 19 combination of echo chambers (community homophily), cross-platform recirculation, and coordinated “peaks” can sustain inaccurate or denialist narratives, even within an ecosystem of diverse actors. This result aligns with recent mappings of socio-environmental disinformation in Brazil, which describe both the political instrumentalization of the media around the Amazon and the need for platform governance and evidence-based interventions (Ferreira, 2023; Intervozes, 2023; UNESCO, 2023). Regulatory episodes involving Telegram in Brazil — such as the court-ordered blocks in 2022 — reinforce that the platform is now a critical infrastructure of public debate and, therefore, a relevant target for information integrity policies (Nicas & Spigariol, 2022). The network dynamics in Figure 4 capture “who talks to whom” and how security and climate framings compete and reinforce each other in a digital environment that amplifies speed, reach, and recontextualization. 5. Conclusion In addition to the well-publicized ecological risks involving the Amazon— such as savannization, loss of forest cover, and climate extremes — there is growing evidence that the climate crisis can trigger or reinforce negative social tipping points, including polarization, distrust, anomie, displacement, and conflict. According to Spaiser et al. (2024), when extreme environmental events or ongoing degradation exceed certain thresholds, these social dynamics feed back into natural systems, weakening mitigation measures, eroding trust in science and institutions, and fostering narratives of denial or climate skepticism. The discourse about the Amazon on Telegram cannot be separated from the broader contexts of media and public policy. Over the past decade, Brazil has witnessed an informational struggle over the Amazon — a dispute in which WhatsApp group networks, forwarded messages on Telegram, YouTube livestreams, and Twitter/X threads have become as impactful as official reports or newspaper editorials. Topics such as deforestation, Indigenous rights, climate change, and national sovereignty have been refracted through the lens of social media, often generating more conflict than understanding. The digital debate has concrete implications for climate action: it can legitimize harmful policies or drive public demand for environmental protection. Through the analysis of 39,000 Telegram messages, we explored how these trends manifest in the content shared across hundreds of channels. This work evaluates temporal trends, thematic clusters, influential actors, and network structures in conversations about the Amazon on Telegram. By investigating the interaction between facts, influence, and narrative framings in these messages — within the context of Brazilian politics and media — we contribute to understanding how digital communication is shaping the future of the Amazon. Carneiro & Tucci The Amazon Biome in Messages 20 Protecting the Amazon Rainforest is not just a matter of enforcing laws on the ground; it also involves engaging public opinion in support of evidence-based environmental conservation efforts. The challenge for policymakers and civil society is to harness the constructive potential of platforms like Telegram — such as informing and mobilizing — while mitigating the risks of disinformation and polarization. Considering the growing hybridization of online and offline public spheres, the future of the Amazon may, in part, be shaped by the dynamics of the digital debate. Thus, public policies for the Amazon region must go beyond reducing deforestation or emissions. It is equally urgent to strengthen social cohesion, institutional capacity, public dialogue, climate literacy, digital governance mechanisms, and information integrity, in order to prevent negative social tipping points. Digital platforms play a dual role: they can be spaces of contestation and disinformation, but also arenas for building resilient narratives. Understanding how these narratives circulate and influence perceptions and behaviors enables the design of broader interventions that consider not only environmental impacts but also the social thresholds that condition collective action in response to the Amazon crisis. The data and analyses presented in this working paper aim to contribute to a clearer understanding of these patterns and their possible implications. Future research may explore two paths. First, investigating how influencers and key channels on Telegram build or dismantle public trust in science and environmental policies, analyzing the mechanisms through which scientific authority is mobilized or contested in their messages. Additionally, understanding the complex dynamics between digital engagement — encompassing social curiosity, mobilization, and activism — and concrete action, examining whether online campaigns and debates effectively translate into public conservation movements or political pressure.
