McIntyre complains that
Briffa's comment leads off with the accusation that I had implied that the recent data had in this chronology had been "purposely selected" by Briffa "specifically because they exhibited recent growth increases". I want to dispense with this up front. While I expressed surprise that there were so few cores, not only did I not imply that Briffa did any sub-selecting, but I specifically said the opposite.
But here's what he did write, on Sept 26:
Unfortunately, to date, people in the field have not honored this responsibility and, to an outside observer, seem to have done no more than pick the version (Yamal) that suits their bias.
That certainly confirms Briffa's accusation, it seems to me: "pick the version" = sub-selecting, and "bias" = data that would imply an upturned blade. You can put a bow-tie on a snake, but it's still a snake.
