• Denialism is concentrated in the central US and South, with strong links to political affiliation, education level, and rural vs. urban residency.
• Platforms like Twitter, fueled by figures like Trump and conservative media, play a key role in spreading denialism.
• Addressing misinformation through education, policy, and social media platform accountability is crucial to combat denialism and build resilience to climate impacts.

Climate change denialism varies geographically within the U.S., with political ideology, economic dependency on fossil fuels, and mistrust in science being key contributing factors. Social media platforms serve as significant channels for influencers to disseminate misinformation. The study utilized Twitter data from 2017 to 2019 to estimate the prevalence of climate change denialism at state and county levels, identify typical profiles of deniers, understand the spread of denialism via social media, and examine the exploitation of events to foster climate change denial attitudes.

The research analyzed 7.4 million geocoded tweets from 1.3 million users, classifying them into categories of belief or denial regarding climate change. By employing a deep learning text recognition model, the study profiled climate change deniers and mapped influential networks on Twitter, offering insights into the dynamics of climate change discourse on the platform.

The study found that climate change denial is most prevalent in the central U.S. and the South, with significant variances within states. Political affiliation emerged as the strongest predictor of climate change denialism, followed by factors like education level and COVID-19 vaccination rates. The analysis also highlighted how social media networks, spearheaded by figures such as Donald Trump and supported by conservative media, play a critical role in disseminating climate change denialism.

The use of Twitter data to analyze public opinion on climate change reveals significant clusters of denialism, particularly in Republican and rural counties. The correlation between denialism and skepticism towards science indicates a broader challenge in addressing science-based public policies. The study underscores the need for targeted educational campaigns and policy interventions to counter misinformation and enhance community resilience against the impacts of climate change.

While the use of AI provides a novel tool for analyzing vast amounts of social media data, the study acknowledges limitations, including potential biases inherent in AI technologies and the challenges of accurately classifying ambiguous or sarcastic content. The ethical implications of using AI for research, especially in sensitive areas like climate change, are also discussed.
