date: Mon, 07 Jan 2002 11:14:02 from: Ian Snowball subject: review chapter to: atte.korhola@helsinki.fi, k.briffa@uea.ac.uk, Nalan.Koc@npolar.no Hi everybody, I submitted our review to Catherine Stickley at the end of last year and it is under the scrutiny of colleagues. I expect criticism for its length and detail. Given the recent appearence of speculative solar forcing papers, the delay meant that I could refer to these as well. Fortunately, the solar forcing/cosmogenic nuclide "bandwagon" is good news for me, as I and Per Sandgren have a detailed paper in press (The Holocene later this year) demonstrating that short term and internally driven variations in Earths geomagnetic field intensity during the Holocene would have had at least the same effect on the production of these cloud condensation nuclei. Fifteen years ago I laughed at the suggestions of a causal relationship between geomagnetic field intensity and climate, but now a mechanism has been proposed! Given the mechanism, it is quite crazy that people ignore (or sweep under the carpet) the possibility of short term variations in global geomagnetic field intensity as a factor influencing records of 14C and 10Be. I'm rambling on... Happy new year.. Ian.
