If anyone can explain to me why I am getting this, and how they have actually produced the solar/temperature link (with a backward sensitivity at that) i’d be very appreciative.

I admit I don’t have access to the actual Science paper

Trouet, V, Esper J, Graham NE, Baker A, Scourse JD, Frank DC (2009) Persistent positive North Atlantic Oscillation mode dominated the Medieval Climate Anomaly. Science 324, 78-80. (pdf)

Found here.

Not sure if this has already been supplied from looking over the thread, but here it is.

Mann is also concerned that the dominance of medieval La Niña conditions now indicated by Trouet’s work might make it more likely that the current man-made warming could also put the El Niño system back into a La Niña mode

Wait a sec. I thought they reconstructed NAO, not ENSO. How did ENSO get in here?

El Niño and the NAO are connected by a process called thermohaline circulation, which drives the “ocean conveyor belt” that shuttles sea water of different density around the world’s oceans.

Oh. No reason to restrict ourselves to discussing NAO when we can extrapolate by looking on down the teleconnective line. Another pea under thimble game.

According to Trouet, a Pacific La Niña mode and a positive NAO mode could have reinforced each other in a positive feedback loop – and this could explain the stability of the medieval climate anomaly.

But did Trouet show this in this paper? Or is she theorizing, extrapolating beyond the data? Or was she misquoted/quoted out of context. Val?

Mann is also concerned that the dominance of medieval La Niña conditions now indicated by Trouet’s work might make it more likely that the current man-made warming could also put the El Niño system back into a La Niña mode, although most climate models so far had predicted the opposite.

The perfect rescue device. Models that are sufficiently vague that anything is consistent with them. Newflash: This is not a proof by lack of contradiction, guys. It’s called a poor hypothesis test. There’s a difference.

It is difficult to find a clear thinking, logical mind who can purely grasp the irony of it all. It is no wonder the AGW train has picked up so much momentum.

Apologies to Mr. McIntyre if I have strayed off topic. I probably never really was On topic. I just appreciate the opportunity to voice my dissenting view as an intelligent, reasonably educated man who’ll never be heard above the voices who would squash it.

I do believe this warming period is real. I also believe that the science behind it has unfortunately been poisoned by politicians (ie Gorites) and others who have emotional and financial motivations to see this hysteria through.

I have serious concerns when I see supposed “unbiased peer-reviewed” talking heads claiming the matter is “settled” and practically mocking those who offer counter debate. If I were a research scientist I should think that I would WANT and DESIRE open dialogue, to have my research scrutinized to further bring us to THE TRUTH. Unfortunately the nature of modern science which depends on funding and financial backing from whoever holds a checkbook has placed integrity on the backburner in favor of publication and notoriety.

I apologize if my sarcasm poisons my POV.

One doesn’t hear the current state of the climate being referred to as “widespread warming”, very often, IMO.
