Hard to say, since I've not seen the paper (I'm working on it). Could be that they used a statistical model, not a climate model??

Here's the full title from Zorita's web page:

E. Zorita, T. Stocker and H. von Storch. How unusual is the recent series of warm years?

Here's link a I just found for folks with access to the AGU site:

EDIT: Yes, they used statistical analysis, not GCM type climate models. Steve McIntyre will have fun with this one!!

Black Dog, are you up at the AGU in SF this week?

No, although I wish I had the opportunity after looking at the program and reading a few abstracts. I'm on the other side of "flyover land". If you have some direct thoughts, my e-mail address can be found from my profile...
