Here is a nice explanation of how some hockey sticks are made.
How bad proxy addition to the mix makes the reconstruction better and better !

and here is Gavin Schmidt telling how tiresome it is to have people repeat the same question again and again...Gavin ends up spitting out crow feathers and slightly exposing Mann08's real skilfulness.

As expected, the pathological dynamic worked it's magic again.

But as to if the proxy can even be calibrated, Gavin can only say
Quote
We don’t know, because it depends on whether the modern anthropogenic effects in Tiljander’s data actually erased the temperature signal – something that is very possible, but not certain
The original researcher, Mia Tiljander, declared them unusable for paleo reconstructions. They are a mainstay of hockey sticks. Gavin says they don't even know if they can be calibrated, or if there is any signal, but they will be used !

This in a study that requires all proxies be calibrated to the instrumental period...
