Claim 3: “Mike S. Schäfer et al, Social media and the changing landscape of climate change communication, Nature Climate Change (2026). DOI: 10.1038/s41558-026-02680-3”
DISPUTED
The claim provides a specific citation for 2026. However, the evidence provided in the Wikipedia results for this index is completely irrelevant (referring to a video game 'Broken Age' and Mike Patton), and the date 2026 is in the future relative to standard publication cycles, suggesting a potential hallucination or error in the claim's citation details despite the study itself existing.
