Recently, Steve McIntyre achieved another 15 minutes of fame by challenging the results of several of dendochronologist Keith Briffa's papers. Briffa rseponded here, and among the points he made was that the origonal data came from
...sub-fossil and living-tree ring-width measurements provided to me by Rashit Hantemirov and Stepan Shiyatov.
Now, Rashit Hatenirov himself has provided an update on his more recent work, 1) justifying original Briffa's selection criteria and 2) arguing that an update to his data using many more trees has essentially corroborated Briffa:
As to reliability of recent increase in tree growth - we have updated our data using many additional subfossil and living trees and using RCS-method. I.e. we used not only long series. Therefore many (120) living trees have been used. Finally, we have got almost the Briffa’s result. These results not published yet. I’m going to prepare paper at the end of this / beginning next year.
A preliminary report can be found (in Russian) here.
We are still waiting for McIntyre's apology.
