Keith Briffa has just published a new paper using the Yamal-Urals regional chronology data, something long sought after via FOIA requests. That data was withheld, citing it wasn’t
cooked done with yet, and that releasing it would damage the reputation of CRU scientists.
After Climategate in 2009, I’m not sure how CRU’s reputation could be damaged any further, but that was the reason given for not sharing the data. Maybe it has to do with the lack of definitive hockey stick and the dwarfing of the present by the Medieval Warm period being counter to some of the unsupportable claims that have been made about tree ring data and unprecedented warming.
Steve McIntyre writes:
In resisting the FOI, CRU said that production of the 2006 regional chronology would damage the reputation of CRU scientists. The 2006 version appears to be the “Urals raw” chronology illustrated in SM9 as Greater Urals (shown below), though it is not identified as such in my first reading. Readers can judge for themselves whether their foreboding was justified.
