BELÉM, Brazil, Nov 12 2025 (IPS) - Concerned scientists at the UN climate conference in Belém are appealing for collective action to combat climate change-related misinformation and disinformation.

The Union of Concerned Scientists (UCS) sounded the alarm over the widespread dissemination of climate disinformation across multiple fronts, including social media and traditional media platforms, warning that it impacts public health, undermines democracy, and weakens the effectiveness of climate policies.

“Disinformation is everywhere. It’s sophisticated. It’s evolving rapidly,” said J. Timmons Roberts, Professor of Environmental Studies and Sociology at Brown University. “Structural power deploys disinformation to preserve the status quo. The fossil fuel industry spends about 10 times as much as the environmental and renewable energy sectors combined.”

Roberts, the Executive Director of the Climate Social Science Network, emphasized the need to understand the tactics, key actors, and the flow of power, money, and information to tackle climate disinformation.

“There’s a series of tactics that offer effective solutions to this disinformation—for example, appealing to conservative identities, to the identities of the people you’re speaking to, and using debunking and pre-bunking strategies,” he said. “You have to have the right messengers.”

In an open letter, a global coalition of scientists, civil society groups, Indigenous Peoples, and faith leaders called on policymakers to take immediate action to combat climate misinformation and uphold information integrity. They emphasized that both the UN and the World Economic Forum have identified climate change and disinformation as among the greatest threats to humanity.

“Governments need to see this [climate disinformation] as a kind of public safety issue,” said Ben Backwell, CEO of the Global Wind Energy Council. “This is not freedom of speech. This is the control of libraries and communications by very confident people.”

He stressed the importance of democratizing media and increasing independent journalism to counter a media ecosystem dominated by a wealthy few.

At a press conference on Tuesday—designated as the official thematic day on information integrity—experts warned that climate misinformation causes real-time harm and that major platforms, including Meta, X, and TikTok, are actively spreading misinformation, disinformation, or false information.

“Disinformation and misinformation are their business model,” said Pierre Cannet, Global Head of Public Affairs and Policy at ClientEarth. “This is why we are calling on countries to join this effort for information integrity—not just at the conference, but also back home—and to enforce laws that address misinformation and disinformation.”

Experts emphasized that collaboration across all levels of society is essential to overcoming coordinated misinformation campaigns, which are often driven by profit motives, particularly from the fossil fuel industry.

Rayana Burgos, a Brazilian political scientist at the Network of Terreiro Communities for the Environment, stated that without truth, there can be no climate justice or final action.

“The fossil fuel industry has polluted our art, and now it’s polluting our information. So, we clearly say: stop the lies, stop the delay,” she added. “We need to act together. Access to information is a human right.”
