From: Tom Wigley To: Timothy Carter Subject: Re: Java climate model Date: Thu, 24 Apr 2003 09:17:29 -0600 Cc: Mike Hulme , Phil Jones Tim, I know about what Matthews has done. He did so without contacting Sarah or me. He uses a statistical emulation method that can never account for the full range of uncertainties. I would not trust it outside the calibration zone -- so I doubt that it can work well for (e.g.) stabilization cases. As far as I know it has not been peer reviewed. Furthermore, unless he has illegally got hold of the TAR version of the model, what he has done can only be an emulation of the SAR version. Personally, I regard this as junk science (i.e., not science at all). Matthews is doing the community a considerable disservice. Tom. PS Re CR, I do not know the best way to handle the specifics of the editoring. Hans von Storch is partly to blame -- he encourages the publication of crap science 'in order to stimulate debate'. One approach is to go direct to the publishers and point out the fact that their journal is perceived as being a medium for disseminating misinformation under the guise of refereed work. I use the word 'perceived' here, since whether it is true or not is not what the publishers care about -- it is how the journal is seen by the community that counts. I think we could get a large group of highly credentialed scientists to sign such a letter -- 50+ people. Note that I am copying this view only to Mike Hulme and Phil Jones. Mike's idea to get editorial board members to resign will probably not work -- must get rid of von Storch too, otherwise holes will eventually fill up with people like Legates, Balling, Lindzen, Michaels, Singer, etc. I have heard that the publishers are not happy with von Storch, so the above approach might remove that hurdle too. _______________________________ _______________________________ Timothy Carter wrote: > > Dear Tom, > > Since you were online yesterday contributing to the "Climate Research" > discussion, I figured that you might be in town to give your views on the > Java Climate Model which, I understand, is based in large part on MAGICC: > > http://chooseclimate.org/jcm/ > > and seems to be getting considerable exposure amongst the policy community > now that Ben Matthews (was he a student of yours at UEA?) has made this > available online. > > I wondered if this has been subjected to "peer review" by the people whose > models it is based on or anyone else, since I have Ministry people here in > Finland asking me if this type of tool is something they should think of > using during the negotiating process! > > It's certainly a smart piece of software, though it seems to have > irritating bugs, like returning to the default state when any little thing > is adjusted.
