There’s a combined discusison of MM05 (GRL) and MàÆàⵢerg et al  in tomorrow’s Science, together with a new spaghetti diagram that differs from the MàÆàⵢerg rendering of proxy data a few posts ago.

Even as greenhouse skeptics revel in what they presume is the downfall of one of global warming’s most prominent supports, paleoclimatologists have come up with yet another analysis. In a paper published this week in Nature, Swedish and Russian researchers present their first entry in the millennial climate sweepstakes.
It’s interesting to see the spin: I thought that MàÆàⵢerg was a kick in the groin for the Hockey Team, but Phil Jones is still gamely arguing:
"The past couple of decades are still the warmest of the past 1000 years.”
I’ve been looking through MàÆàⵢerg and don’t exactly see how one can draw this conclusion from MàÆàⵢerg other than gross splicing. The $64 question for the splices is surely this: the proxies should be going off the charts in the 1990s. I’ve not tried to look through recent proxy collections systematically and it’s a big job, but I don’t get the sense that they are going off the charts or the Hockey Team would have used them. If the proxies don’t pick up the loud 1990s, how do we know that they didn’t pick up some other loud period in the MWP. I’m probably going to spend some time on this topic.
