Tip of the hat to Marcel Crok for alerting me to the release of the names of the chapter authors of the IPCC's Fifth Assessment Report.
No Briffa, Jones or Mann, but the paleoclimate chapter includes Tim Osborn. Having someone from CRU onboard might well be seen as somewhat controversial if not downright provocative. Other familiar names are Eystein Jansen, Bette Otto-Bleisner and Juerg Luterbacher.
Marcel advises that many of the authors were also on board for AR4. Perhaps nobody else wants to be involved any more.
