We also show that pre-existing political cleavages—anti-internationalist populist sentiments—provide a pathway for this spillover, helping link climate skepticism to COVID-19 vaccine hesitancy. This overlap further entrenches anti-science sentiment across different policy domains.

Quarterly difference in toxicity between tweets containing references to international organizations and those that do not, compared to the baseline quarter (2019 Q4). The lighter confidence intervals are computed from standard errors clustered at the Twitter account level.

By analysing millions of climate change and climate science posts, we found that mentions of COVID-19 or Anthony Fauci derailed climate conversation into incivility and contentiousness. These patterns strengthened during major pandemic events.

Presence of COVID-19 content and incivility of climate posts. Panel A shows coefficient estimates from linear probability model of toxicity in climate posts across three social media systems. Panel B shows coefficient estimates from Cox proportional hazards models of toxicity onset in climate conversations on Twitter. Panel C shows temporal trends in daily climate tweet toxicity by difference in content. Panel C’s inset shows the temporal trends for climate science tweets and Reddit comments
