From: "Michael E. Mann" To: Tim Osborn Subject: Re: Fwd: Re: Ruherford et al 2005 Date: Wed, 26 Apr 2006 10:49:23 -0400 Reply-to: mann@psu.edu Cc: Scott Rutherford , Keith Briffa , Phil Jones thanks Tim, I'm saddened to hear that this bozo is bothering you too, in addition to NCAR, NSF, NAS, IPCC and everyone else. Rest assured that I won't ever respond to McIntyre should he ever contact me, but I will forward you any email he sends related to this. I assume Scott feels the same way... I hope you're having as nice a spring as we are here. See you in June? mike p.s. we have some interesting new reconstructionbased on RegEM using a greatly expanded multiproxy network (which includes the MXD data). I hope to send you guys shortly. It is our hope that you'll consider being co-authors. This to come soon...
