[...] worthy than the hockey team's cherry picked tree rings? For their part, the hockey team is a bit lacking in consistency WRT deciding what is and what isn't a suitable temperature proxy. In any event, nothing you've posted shows causation between the weather in Peru and alleged AGW. [...]

re #141,

My position would be to err on the side of caution. The picture has not yet been authoritatively sourced, and if a collage, then CA is open to a charge of misrepresentation. I emailed a friend who works professionally with computer graphics and prior to that for decades as a photo engraver and asked whether it looked genuine from the technical point of view. His reply:

“I would say with absolute certainty, the image of that tree on a desert is fake, in as much as the tree has been cut and pasted onto the background. If you were sitting here in front of the image with me I could point out my reasons for being so certain.”

twq, you are entrely free to post of a picture, or even three pictures of Dulan junipers which you judge to be representative. Now, please, can we move this back to the correct thread?

Whether Shao remove it or not is irrelative to that steve should remove it. If you insist keeping it here, it is your fault. What do you say?

twq, I suspect that you have posted this in the wrong thread … but in any case, since you are upset about the picture being used inappropriately, I’m sure that you have contacted Professor Shao and asked her to remove it from her publication.

What was her reply to you?

Steve, since it is a non-existant thing, why do you still keep this beutiful picture “a tree in the desert ” here? I am fed up with this picture. It gives CA readers wrong visual effect. Almost all the CA readers regard it as a Dulan juniper, although it is definitely wrong. I suggest you delete it as far as Science is concerned.

One and the same proxy can be a proxy for T,P and even more quantities. One example are records for North-East Brasil rainfall strongly related to ENSO and therefore to the typical SST key regions (NINO3 etc.). When you go out of the directly observed intervall you make assumptions about stable teleconnections (e.g. ENSO goes on provoking displacements of the Hadley-Walker cell and therefore producing rainfall anomalies in Brazil in this case. The problem of Soon/Balliunas is that they didnt spend one second (or one line in their article) to think about these kind of climate relations (and it’s therefore it shouldnt have passed ever peer review).
Otherwise I agree with the critic here (point 1 and 2 of the beginning of the post).

Umm…it sucks. Probably about twice as numerous as the Oz study, but still not up to par, given all the possible confounding variables. I would like to see within site variation, though. I’m very interested in that.

Re 133, TCO, I must admit, I find your childish games with my name most revealing about your level of maturity and sophistication … but it’s not a problem, I did the same thing in high school myself, so don’t worry, I suspect you’ll grow out of it.

On the other hand, thank you for your comment on sample size. I agree with you about the small sample size in the Australian study … but I note that you have not made the same objection re the Treydte et. al. paper. Probably just a coincidence …

Treydte used 7 trees from one of four sites, and “4-5 trees” from each of the other three sites.

You have a comment on that?

I started using it. That last one, was just me making fun of myself. Plus I’m sober now. Had a great weekend…
