Fig. 2: Prevalence of claims.
From: Large language model reveals an increase in climate contrarian speech in the United States Congress
Figure a provides the distribution of the top 15 level-2 claims based on the taxonomy in Fig. 1, while b provides the distribution for level-3 claims. Figures c–e plot the proportion of each major, level-1 claim from 1994 to 2024. Note that due to major differences in the prevalence of solutions, energy, and science-based claims, the y-axis for Figures c–e use different scales.
