Climate misinformation is rife on social media – and poised to get worse

The decision by Meta, the parent company of Facebook and Instagram, to end its fact-checking program and otherwise reduce content moderation raises the question of what content on those social media platforms will look like going forward.

One worrisome possibility is that the change could open the floodgates to more climate misinformation on Meta’s apps, including misleading or out-of-context claims during disasters.

In 2020, Meta rolled out its Climate Science Information Center on Facebook to respond to climate misinformation. Currently, third-party fact-checkers working with Meta flag false and misleading posts. Meta then decides whether to attach a warning label to them and reduce how much the company’s algorithms promote them.

Meta’s policies have fact-checkers prioritizing “viral false information,” hoaxes and “provably false claims that are timely, trending and consequential.” Meta explicitly states that this excludes opinion content that does not include false claims.

The company will end its agreements with U.S.-based third-party fact-checking organizations in March 2025. The planned changes slated to roll out to U.S. users won’t affect fact-checking content viewed by users outside the U.S.. The tech industry faces greater regulations on combating misinformation in other regions, such as the European Union.

Fact-checking curbs climate misinformation

I study climate change communication. Fact-checks can help correct political misinformation, including on climate change. People’s beliefs, ideology and prior knowledge affect how well fact-checks work. Finding messages that align with the target audience’s values, along with using trusted messengers – like climate-friendly conservative groups when speaking to political conservatives – can help. So, too, does appealing to shared social norms, like limiting harm to future generations.

Heat waves, flooding and fire conditions are becoming more common and catastrophic as the world warms. Extreme weather events often lead to a spike in social media attention to climate change. Social media posting peaks during a crisis but drops off quickly.

Low-quality fake images created using generative artificial intelligence software, so-called AI slop, is adding to confusion online during crises. For example, in the aftermath of back-to-back hurricanes Helene and Milton last fall, fake AI-generated images of a young girl, shivering and holding a puppy in a boat, went viral on the social media platform X. The spread of rumors and misinformation hindered the Federal Emergency Management Agency’s disaster response.

What distinguishes misinformation from disinformation is the intent of the person or group doing the sharing. Misinformation is false or misleading content shared without active intention to mislead. On the other hand, disinformation is misleading or false information shared with the intent to deceive.

Disinformation campaigns are already…
