Spotting Social Media Misinformation On Climate Change
Dear EarthTalk: How can I spot social media misinformation regarding climate change and what can I do to combat it?
—Maurice Maloney, Providence, RI
Climate misinformation is a term that refers to false or deceiving claims about climate change, sustainability, or climate solutions. Disinformation spreads rapidly and creates tension around environmental issues. Misinformation also “fuels political extremism and puts lives at risk,” according to COP30 Special Envoy for Information Integrity Frederico Assis.
Researchers at Texas A&M University and Ripple Research, a non-profit advisory firm, found that misinformation is typically centered around two narratives, claiming either environmental research is invalid or solutions are not viable. “One of the most powerful [types of disinformation] is saying that it’s too late,” says UN Verified Champion Maria Clara Moraes. These false claims are hindering advancements towards climate change solutions and sustainability initiatives, as recognized in November 2025 at COP30, the United Nation’s 30th Climate Change Conference. “There is a broad recognition that disinformation can affect and compromise every part of the COP process,” says Assis, “diplomatic negotiations, the action agenda, or mobilization and summits. All out efforts will be at risk if we fail to tackle disinformation properly, which stems from denialism.”
Communities and organizations around the globe are working together to fight the spread of misinformation. For example, COP30 hosted twelve nations who created a program against misinformation and signed the first Declaration on Information Integrity on Climate Change. Brazil’s Secretary of Digital Policies João Brant says the goal is to “create a wave of truth”. Brazil was one of the many initiators of the Declaration. The initiative’s global fund has generated support from around 100 countries who have submitted about 450 proposals, according to UN News.
In addition to global action, individual decisions can weaken the influence of misinformation. If a post or article lacks a credible source, employs strong emotional appeals, presents logical fallacies, or includes cherry-picked data, conduct more research to determine the statement’s credibility. Readers can use fact-checking websites such as Science Feedback and FactCheck to help assess a source’s reliability. If a reader chooses to respond to or comment directly on the misinformation, they must act diligently to not inadvertently magnify the false claim on a social media algorithm. For example, when responding to misinformation, do not repeat the false claim itself. Experts say anyone commenting on a misinformation post or article should address it with a “truth sandwich”: start by relaying the truth, address the false claim without repeating it, and then end the comment with a truthful statement. Commenters should also include credible sources and scientific studies when responding. Additionally, many social media algorithms allow users to report posts that include false claims. Readers can work together to stop misinformation by staying alert online, acting diligently, and responding to false claims in an effective way.
