Jim has already drafted something on ENSO/temp relationships and I made a few comments, once we have a revised version of that can send on to you for further comment/addition/revision etc. thanks for the update re CA--caught a hint of this latest fuss in a comment that came in at RC (which we deleted from the queue). Sounds like they're moving from person to person, first harassed Ben earlier this year, now you, who knows who is next. I've been trying to no avail to get some journalist to look into their funding, industry connections, etc. they need to be exposed--badly! by the way, are you going to the paleo meeting being hosted by Gabi and crew in Edinburgh next summer (July 12-13 I believe)? If not, perhaps I can schedule a short visit at CRU to see you, Keith, and the gang either before or after, once I know schedule... mike On Jul 29, 2009, at 11:44 AM, Phil Jones wrote: Mike, I replied quickly to Grant to say I'm in. All of CRU is away tomorrow - so we're due for deluge at Keith's house, where we hope to have a barbecue. I've printed if off and will get back to Grant tomorrow or first thing Friday. Looks to have too many diagrams, but we can pick and choose. I recall comments have a limit on diagrams. A bit on history of ENSO would be good to sneak in. The paper I sent earlier has many of the refs but only one of Walker's. Have had a difficult few days this week - with 50 FOIs from an orchestrated climate audit campaign. We have a path through it now. It is just a pure time wasting effort. Cheers Phil At 16:35 29/07/2009, you wrote: thanks Grant, the paper is starting to shape up well now. Jim and I (well, mostly Jim, w/ some input from me) are iterating on a blurb about past studies on ENSO/temperature relationships and should have something for you soon on that, As James has pointed out, its important to stick to the key points and not get sidetracked with nonsense. I would avoid any commentary on their ignorant ramblings about the Hadley Cell, etc. We want to cut straight to the deep flaws in their analysis which are, in order of importance in my view, 1. indefensible use of a differencing filter, which has the effect of selectively damping low-frequency variability and renders any conclusions about factors underlying long-term trends completely spurious. 2. ignoring the fact that the influence of ENSO on global temperature has been known for decades, and much better quantified in past studies than in the current deeply flawed analysis. 3. the selective use of a flawed temperature data and curious splicing in of inappropriate recent data (UAH TMT) to further suppress trends. A bit of overkill given that they already eliminated the trends anyway. Guess they wanted to play it extra cautious just in case some bit of warming trend tried to sneak in. The other stuff is just a distraction. mike On Jul 29, 2009, at 10:51 AM, Grant Foster wrote: Gentlemen, Attached is a zip file with LaTeX and pdf for a first draft. I've included everybody's name (in alphabetical order after mine), but of course it should only include in submission those who give explicit consent. There are a few other issues. One is that MFC have recently removed the pdf version of their paper from the "New Zealand Climate Coalition" website. They've replaced it with this: [1]http://nzclimatescience.net/index.php?option=com_content&task=view&id=502&Itemid=1 which refers to a graph showing only part of figure 7, and suggests that there's not trend in GTTA so "nothing to worry about." Yet the plotted GTTA is from UAH TMT (*not* TLT) so of course it shows no trend, and the MT channel is contaminated by stratospheric cooling. In figure 7 of the paper itself they compare the 50-year record of SOI and GTTA, but their graph of GTTA is made of RATPAC-A data until 1980 grafted onto UAH TMT data afterward -- hence the lack of an obvious trend. I think this too should be mentioned, especially as the entire RATPAC-A record shows a very pronounced trend. One last thing: there's a lot of stuff in the paper about Hadley cells and heat transport and so forth. I suspect this is really a bunch of gobbledygook -- but I don't know. But I'll bet you guys do.
