The Union of Concerned Scientists (UCS) developed an evolved methodology to track 'attacks on science'—defined as political interference in federal science—starting in January 2025. The system combines automated R scripts for RSS feed collection and keyword filtering with human content analysis to categorize attacks by type, topic, and stage of completion. The methodology aims to systematically capture a comprehensive breadth of attacks in perpetuity, including those that are only threatened, to document their chilling effects on the federal scientific enterprise.

QuotaClimat has issued 17 recommendations to the French government to ensure the upcoming national plan on environmental and climate information effectively tackles disinformation. These proposals focus on monitoring media coverage, protecting environmental spokespeople, funding research, and strengthening regulatory frameworks like the Digital Services Act and the roles of VIGINUM and Arcom. The initiative follows France's commitment to the Global Declaration for Climate Information Integrity at COP30 and recommendations from the High Council for the Climate 2025 report.

The document outlines best practices for journalists covering climate science, emphasizing the need to prioritize human impact over raw data and to look beyond abstracts to find the most relevant information. It provides criteria for evaluating the reliability of studies, such as peer review and the avoidance of predatory journals, while cautioning against confusing correlation with causality. Additionally, it lists several tools and databases, including the Global South Climate Database and Retraction Watch, to help reporters verify sources and connect with experts.

The report identifies 47 uncontested cases of climate disinformation on six German TV channels from April 2025 to April 2026, noting that both public and private broadcasters are vulnerable. Political figures and guests are the primary sources of this disinformation, with a significant portion of cases focusing on the economic and technical reliability of the energy transition.

The report identifies 815 cases of climate misinformation across 44 audiovisual channels in Brazil, Spain, France, and Poland. It finds that private media are significantly more porous to disinformation than public media, with 85% of cases occurring in private outlets. A strong negative correlation exists between the volume of climate coverage and the prevalence of disinformation, meaning media that cover climate issues more frequently tend to spread less misinformation. The study highlights a shift toward 'new climate denial,' which focuses on obstructing climate action and attacking renewable energy rather than denying the existence of warming. Renewable energy is a primary target, often linked to narratives of lost sovereignty, anti-EU sentiment, and social decline. The report recommends improved journalist training, stricter guest selection protocols, and increased accountability for broadcasters.

The report identifies 815 cases of climate disinformation across 44 audiovisual channels in four countries, finding that private media are significantly more prone to spreading such content than public media. It highlights a negative correlation between the volume of climate coverage and the prevalence of disinformation, suggesting that consistent reporting reduces the risk of misinformation. The analysis reveals distinct national narratives: France focuses heavily on renewable energy costs and inefficiency; Poland links climate policy to anti-EU sentiment and industrial decline; Brazil emphasizes agribusiness virtues and climate denial; and Spain shows a unique susceptibility to 'chemtrails' conspiracy theories. The document recommends journalist training on obstructionist discourses, more rigorous guest selection for TV sets, regular environmental coverage, and the establishment of accountability frameworks for disinformation spreaders.

The text asserts that the United States has pioneered modern climate science and cornerstone innovations in renewable energy and battery storage, which provide economic and security benefits. It warns that shifting federal priorities are creating challenges for funding and institutional support, urging a reinforcement of these resources to ensure future American progress and global leadership.

The report outlines six key takeaways from participatory climate vulnerability assessments conducted in nearly 100 communities across Mozambique, Zambia, and Zimbabwe between 2024 and 2025. It emphasizes the need to integrate community knowledge with scientific data, involve local governments to institutionalize adaptation, and manage expectations during overlapping crises. The document argues that these assessments are foundational for locally led adaptation by linking local insights with climate projections to understand risks across diverse social groups and ecosystems.

The report details the Inter-American Court of Human Rights' (IACtHR) Advisory Opinion 32/25, which recognizes the right to a healthy climate as an autonomous and justiciable right. It establishes that States have binding obligations to mitigate greenhouse gas emissions, adapt to climate impacts, and provide integral reparations. The Court introduces a high standard of 'enhanced due diligence' for climate action and recognizes Nature as a subject of rights. It also outlines specific protections for vulnerable groups, including Indigenous Peoples, LGBTIQ+ persons, persons with disabilities, and future generations, while emphasizing the necessity of environmental democracy through access to information, public participation, and the protection of environmental defenders.

The report analyzes climate disinformation in French and Brazilian mainstream media, finding that while France sees a high volume of structured disinformation narratives—particularly regarding energy and mobility—Brazil experiences a 'media invisibility' of environmental issues driven by agribusiness and political influence. It highlights the role of public broadcasting as a bulwark in France and warns that disinformation during extreme weather events can undermine emergency responses. The authors recommend strengthening media regulation, improving journalist training, and institutionalizing semi-automated disinformation detection systems.

The document argues that the Trump EPA's proposal to revoke the 2009 endangerment finding relies on misinterpretations of the Clean Air Act and fringe science. It details how the agency seeks to narrow the definition of 'air pollution' to exclude global harms and challenges the scientific consensus on climate change using a Department of Energy report authored by climate skeptics. The briefing notes that while the proposal specifically targets motor vehicle emission standards for model years 2012 to 2027 and beyond, it also undermines the legal basis for greenhouse gas regulations on power plants and oil and gas facilities.

The report details the methodological framework for identifying 'attacks on science' (AOS), defined as actions by elected officials or political appointees that result in the censoring, manipulation, or misinforming of scientific data. It describes the use of human coding for news articles, analysis of federal funding data from USASpending.gov, and tracking of federal advisory committee terminations. The methodology specifically addresses the tracking of federal workforce cuts, the impact of Clean Air Act exemptions on overburdened communities using spatial buffers, and the monitoring of federal environmental webpages via the Environmental Data and Governance Initiative (EDGI).

The Council on Strategic Risks warns that the reported firing of staff and potential closure of climate.gov would erode the health and security of Americans. The site serves as a vital bridge between scientists and the public, providing STEM resources, extreme weather outlooks, and the US Climate Resilience Toolkit for farmers and policymakers. The author asserts that losing this 'national security asset' would lead to higher disaster recovery costs, increased vulnerability to misinformation, and a 'brain drain' of US scientists to regions like the European Union.

The 33rd Meeting of the IAI Conference of the Parties approved the 2025-2026 operating budget, the Asunción Declaration on Water Security, Biodiversity, and Climate Resilience in the Americas, and a new policy on open access to data and publications. The meeting also extended invitations for the World Meteorological Organization (WMO), the American Geophysical Union (AGU), and the Venezuelan Institute for Scientific Research (IVIC) to become Associates of the Institute.

The report identifies a persistent presence of climate disinformation in French mainstream media, noting 128 certified cases over three months. It highlights a significant over-representation of such content in private media, particularly Sud Radio, and observes peaks in disinformation coinciding with major political events. The analysis also employs the CARDS framework to identify 373 instances of 'inaction discourse,' primarily targeting climate solutions and messengers. The authors call for increased environmental coverage, better journalist training, and stronger regulatory action by ARCOM.

The document outlines a strategy for the advertising industry to avoid inadvertently incentivising harmful content. It proposes a four-step action plan: setting internal standards and risk protocols, incentivising quality journalism, optimising media mixes to avoid platforms that commercialise inaccuracies, and enforcing supply chain accountability. The guide emphasizes that information integrity is essential for human rights and a sustainable future, noting that ads appearing alongside hate speech can lead to a 35% drop in click-through rates and a decrease in brand affinity.

The document identifies a strategic shift from outright climate denial to 'strategic doubt,' where influential economic and political actors—including fossil fuel companies and right-wing populist movements—deliberately spread misleading information to obstruct climate action. It highlights that policymakers are primary targets of these campaigns, which are disseminated through traditional media, social media, and non-public corporate channels. The report notes a significant research gap in the Global South and proposes four policy interventions: mandatory standardized carbon reporting, litigation against greenwashing, the creation of cross-sectoral voluntary alliances, and the enhancement of scientific and media literacy for the public and officials.

The report identifies a crisis of information integrity about climate science, characterized by a shift from outright denial to more nuanced skepticism and 'response skepticism' regarding climate solutions. It documents how powerful economic interests, particularly the fossil fuel industry, and political actors use strategies like greenwashing, delay, and obstruction to undermine scientific consensus. The review highlights the role of social media algorithms, bots, and 'source media' (such as corporate reports) in amplifying misleading narratives. It concludes that while individual-level interventions like inoculation and education are valuable, systemic governance through public regulation, standardized corporate reporting, and litigation is essential to restore information integrity.

The report identifies a shift from outright climate denial to 'strategic skepticism,' where powerful economic and political actors intentionally spread misleading narratives to obstruct climate action. It highlights that policymakers are primary targets of this disinformation, which is disseminated through corporate sustainability reports, lobby groups, and social media. The document argues that this environment erodes public trust in science and creates a feedback loop of political inaction. To counter this, the report recommends standardized carbon emission reporting, legal recourse against greenwashing, the creation of multi-stakeholder coalitions, and enhanced science and media literacy education.

The report identifies a shift from outright climate denial to 'strategic skepticism,' where powerful economic and political actors—including fossil fuel companies and right-wing populist movements—undermine climate action by questioning the viability and cost of solutions. It highlights that policymakers are primary targets of this disinformation, which is disseminated through social media, traditional media, and corporate sustainability reports. This erosion of information integrity leads to a loss of public trust in climate science and a feedback loop of political inaction. The document recommends four key interventions: legislation for standardized carbon reporting and content labeling, judicial action against greenwashing, the formation of cross-sector coalitions, and enhanced scientific and media education for the public and policymakers.
