Muir Russell reported Briffa’s claim that “Wahl was asked for comment on text as a knowledgeable and objective arbiter”. The indolent Muir Russell did not comment on whether Briffa’s description of Wahl as “objective” was plausible.
In a Climategate letter of July 27, 2006, Wahl wrote to Briffa (733. 1155402164.txt):
I’ve also been a lot involved with helping to get a person from the Pew Center for Global Climate Change ready to testify in front of the House Energy and Environment Committee tomorrow. That is why I couldn’t get this done and sent to you earlier today. Send Mike Mann and Jay Gulledge (Pew Center) all good thoughts for strength and clarity… Peace, Gene
An “objective arbiter” CRU-style.
