Fighting Climate Misinformation Ahead of COP30: The High Stakes in the Battle for Truth

As the world prepares for COP30 in Belém, Brazil this November, one of the most urgent challenges facing climate advocates, scientists, and policymakers is no longer just about cutting emissions or securing finance, it’s about fighting raw, undiluted lies. According to the International Panel on Information Environment (IPIE), climate misinformation has emerged as a coordinated, systemic threat, deliberately orchestrated by vested interests, political actors, and digital platforms to distort public understanding and delay urgent climate action.

In a recent IPIE webinar on climate misinformation, Professor Klaus Bruhn Jensen, Chair of IPIE’s Scientific Panel on Information Integrity about Climate Science, revealed that climate-related falsehoods are increasingly sophisticated, algorithmically amplified, and strategically targeted. Drawing from a forthcoming IPIE report reviewing over 300 studies between 2015 and 2025, Jensen argued that addressing misinformation is now essential to preserving the integrity of international climate agreements.

This position is backed by independent research. A 2022 report by Avaaz showed that Facebook failed to flag or remove climate falsehoods in more than 70% of cases, despite the content being demonstrably false and widely viewed. Such misinformation – most often repackaged in emotionally resonant or humorous formats – spreads rapidly through platforms like Youtube, TikTok, and X (formerly Twitter), where algorithms are seen to reward engagement rather than truth.

But social media is only one layer of the disinformation web. The fossil fuel industry has long played a central role in undermining climate science. A 2023 report by Influenza Map, an independent think tank that produces data-driven analysis on how business and finance are impacting the climate crisis https://influencemap.org/briefing/The-Carbon-Majors-Database-2023-Update-31397 revealed that while oil majors like ExxonMobil and Chevron have publicly promoted their commitment to net-zero goals, they at the same time channeled millions of dollars into lobbying against climate regulation and misleading advertising. These tactics, often branded as greenwashing, create a contradictory public narrative that confuses consumers and weakens policy support.

State actors also contribute significantly to climate misinformation. A 2021 investigation by the Oxford Internet Institute OII (https://www.oii.ox.ac.uk/)  detailed how state-linked media in countries like Russia and China spread narratives portraying Western climate policies as neocolonial, hypocritical, or economically destructive. These messages are especially potent and resonate well in developing nations, where fossil fuels are often tied to national development and sovereignty.

Such messages do not always rely on denial. Increasingly, they adopt delayist arguments that claim that while climate change is real, acting now is too costly, uncertain, or unfair. A study by the Center for Countering Digital Hate (CCDH) identified a group of websites dubbed the “Toxic Ten,” responsible for nearly 70% of climate denial content shared on Facebook in 2021.

IPIE’s emphasis on targeting misinformation at its roots—by exposing its funders, understanding its channels, and tracking its evolving strategies—is therefore not just timely, but necessary. Yet this call to action is not without its detractors. Some critics argue that such efforts risk impinging on free speech or creating centralized gatekeepers of “truth.” Indeed, Youtube’s 2021 move to demonetize climate denial content sparked backlash from content creators and libertarian commentators who accused the platform of censorship. https://www.buzz.ie/tech/google-youtube-unveil-new-measures-25171471

Nevertheless, there is growing consensus that combating misinformation requires more than just removing bad content – it requires building societal resilience. Groups like Climate Outreach in the UK have pioneered community-based messaging strategies that leverage trusted messengers – such as farmers, religious leaders, and local educators – to shift perceptions from within. Their work has shown that values-based communication can outperform technical arguments in mobilizing public support for climate solutions.

Similarly, fact-checking initiatives such as Climate Feedback https://climatefeedback.or play a crucial role in maintaining online information integrity. Staffed by climate scientists, the platform analyzes viral claims and rates their scientific credibility, providing much-needed clarity in a landscape clouded by half-truths and pseudoscience.

Journalists and media organizations, too, bear responsibility. Traditional norms of “both-sides” reporting have proven harmful in climate coverage, often giving fringe views undue legitimacy. Outlets like Carbon Brief (https://www.carbonbrief.org) and Inside Climate News https://insideclimatenews.org  have led the way in evidence-led journalism, focusing on solutions, accountability, and clarity rather than controversy or political theatrics.

As COP30 is about to begin in Belém, Brazil, the stakes for fighting climate misinformation have never been higher. Climate misinformation doesn’t just shape opinion, it shapes policy. It erodes trust in science, deepens polarization, and delays urgent action in a rapidly closing window of time. As Professor Jensen, Chair of IPIE’s Scientific Panel on Information Integrity about Climate Science put it, “the climate crisis is also an information crisis.” If left unchecked, false narratives may not only derail international negotiations but also shut down the global push toward decarbonization.

To secure a livable future, stakeholders such as governments, big tech companies, journalists, and activists must treat the fight against misinformation as a climate priority in itself. The battle for a sustainable planet cannot be won without first winning the battle for truth.
