From: Jim Salinger To: Kevin Trenberth Subject: Re: ENSO blamed over warming - paper in JGR Date: Wed, 29 Jul 2009 06:22:53 +1200 Cc: Phil Jones , Michael Mann , j.renwick@niwa.co.nz, b.mullan@niwa.co.nz, Gavin Schmidt , James Annan , Grant Foster Good morning all from tomorrowland (Wednesday!) Gosh, you have all been very busy overnight here. Thank you, and Mike & I will start wordsmithing our section. We now have (in IPCC terms) a nice bunch of LA's and CAs for this commentary!
