The ability to pick and choose which samples to use is an advantage unique to dendroclimatology.

How do you think early gold miners went about their panning, since antiquity and probably before statistics were invented?

enhancing signal
enhancing desired signal

There’s a difference, and Esper’s choice of words – “enhancing desired signal” – is most questionable. So, yes I do object. What the hell is he playing at?

The errors are evidently (i.e. by eye) serially correlated and the sequence should be differenced before regression is performed. I don’t think it’d make a huge difference to the estimated parameters (the fit looks pretty good), but we’re trying to be methodologically correct, right?

If you can believe Wikipedia, he was born in 1968.

As noted in the update, it seems to me that a stratification by site is a more sensible sort of stratification than the ad hoc split between Yong and Old.

“This seems to be an ongoing and important contribution to the climate modeling field…”

…and will allow those papers to be discounted when formal assessments are made.

(In my dreams, I know, but surely if a series of calculations is not repeatable it is not science?)
