For the very first time, the Climategate Letters “archived” the deleted portion of the Briffa MXD reconstruction of “Hide the Decline” fame – see here.
Gavin Schmidt claimed that the decline had been “hidden in plain sight” (see here. ). This isn’t true. The post-1960 data was deleted from the archived version of this reconstruction at NOAA here and not shown in the corresponding figure in Briffa et al 2001, though pre-calibration values were archived in a different NCDC file here. While the decline was shown in Briffa et al 1998 and Briffa 2000, it was not shown in the IPCC 2001 graph, one that Mann, Jones, Briffa, Folland and Karl were working in the two weeks prior to the “trick” email (or for that matter in the IPCC 2007 graph, an issue that I’ll return to.) For now, here is a graphic showing the deleted data in red. A retrieval script follows.
Show the Briffa et al reconstruction through to its end; don’t stop in 1960. Then comment and deal with the “divergence problem” if you need to. Don’t cover up the divergence by truncating this graphic. This was done in IPCC TAR; this was misleading (comment ID #: 309-18)

I think that trying to adopt a timeframe of 2K, rather than the usual 1K, addresses a good earlier point that Peck made w/ regard to the memo, that it would be nice to try to “contain” the putative “MWP”, even if we don’t yet have a hemispheric mean reconstruction available that far back…

thanks Phil,
Perhaps we’ll do a simple update to the Yamal post, e.g. linking Keith/s new
page–Gavin t? As to the issues of robustness, particularly w.r.t. inclusion of the Yamal series, we actually emphasized that (including the Osborn and Briffa ‘06 sensitivity test) in our original post! As we all know, this isn’t about truth at all, its about plausibly deniable accusations,

I really wish I could be more positive about the Kyrgyzstan material, but I swear I pulled every trick out of my sleeve trying to milk something out of that. It was pretty funny though – I told Malcolm what you said about my possibly being too Graybill-like in evaluating the response functions – he laughed and said that’s what he thought at first also. The data’s tempting but there’s too much variation even within stands. I don’t think it’d be productive to try and juggle the chronology statistics any more than I already have – they just are what they are (that does sound Graybillian).

Here are some speculations on correcting SSTs to partly
explain the 1940s warming blip.
If you look at the attached plot you will see that the
land also shows the 1940s blip (as I'm sure you know).
So, if we could reduce the ocean blip by, say, 0.15 degC,
then this would be significant for the global mean -- but
we'd still have to explain the land blip.
I've chosen 0.15 here deliberately. This still leaves an
ocean blip, and i think one needs to have some form of
ocean blip to explain the land blip (via either some common
forcing, or ocean forcing land, or vice versa, or all of
these). When you look at other blips, the land blips are
1.5 to 2 times (roughly) the ocean blips -- higher sensitivity
plus thermal inertia effects. My 0.15 adjustment leaves things
consistent with this, so you can see where I am coming from.

And about the data dump, now you're claiming that ALL the dumped data (including paper and tapes) is still at the MET office, all the data kept from around thw world?
www.timesonline.co.uk...
Nice try.
And this goes right into the heart of my arguments elsewhere about the sanctity of adjusted data. They've dumped all their raw data so the world will have to jump through hoops attempting to make the same reconstructions to even see how they arrived at their results. And you call this science.
However, as you have something new here about the CRU - they don't actually collect any temperature data of their own. The data deleted was just mirrored at the original met offices. It's still there at the original source.
SCIENTISTS at the University of East Anglia (UEA) have admitted throwing away much of the raw temperature data on which their predictions of global warming are based.
It means that other academics are not able to check basic calculations said to show a long-term rise in temperature over the past 150 years.
The UEA’s Climatic Research Unit (CRU) was forced to reveal the loss following requests for the data under Freedom of Information legislation.
The data were gathered from weather stations around the world and then adjusted to take account of variables in the way they were collected.
The CRU is the world’s leading centre for reconstructing past climate and temperatures. Climate change sceptics have long been keen to examine exactly how its data were compiled. That is now impossible.

And you're speaking matter-of-fact about what data the Met did/didnt/dont have, in terms of thats the only data 'dumped', without any form of citation whatsoever.

This, people, is blatant data-cooking, with no pretense otherwise. It flattens a period of warm temperatures in the 1940s 1930s — see those negative coefficients? Then, later on, it applies a positive multiplier so you get a nice dramatic hockey stick at the end of the century.
All you apologists weakly protesting that this is research business as usual and there are plausible explanations for everything in the emails? Sackcloth and ashes time for you. This isn’t just a smoking gun, it’s a siege cannon with the barrel still hot.
