Climate Change 2021: The Physical Science Basis (IPCC AR6 WG1)
"It is unequivocal that human influence has warmed the atmosphere, ocean and land." Direct attribution statement with full uncertainty quantification.
Every citation behind the score, with its stance, evidence mass mᵢ, recency-decayed mass, and share of the total. The score is reproducible from exactly these rows.
"It is unequivocal that human influence has warmed the atmosphere, ocean and land." Direct attribution statement with full uncertainty quantification.
Found 97.1% endorsement of anthropogenic warming among abstracts taking a position. Heavily replicated; Powell 2015 and others reach similar figures.
Formal fingerprint detection-and-attribution across independent models and observational datasets.
Climate models published since 1970 accurately projected subsequent warming once actual forcings are accounted for.
Argues solar variability contributes more than IPCC estimates suggest, but does not refute anthropogenic dominance. Counted as partial dissent on magnitude, not attribution.
Argues for low climate sensitivity. Subsequent papers (Trenberth et al. 2010, Dessler 2011) found methodological errors; included for completeness with reduced weight.
