Gareth,
It seems to me, from reading your email, that you do not realize that
this is precisely what MAGICC/SCENGEN already does -- i.e., it uses the
scaling method that Ben Santer and I 'invented' in the late 1980s to get
time dependent patterns of future climate change. I am attaching a
description of the method as we employ it.
The current CDROM version uses only a SAR version of the UD-EBM. Of
course, there is a TAR version that Sarah used for the TAR, developed by
me and Sarah -- but mainly Sarah. This has not yet been put into
MAGICC/SCENGEN, although I am in the process of doing so (along with
making a number of other changes to the software). We do not normally
give the code for TAR/MAGICC to others unless it is as part of a
collaborative project. As Mike Hulme noted, what we can do for/with you
will have to be a joint decision with me and Sarah.
The issue of how well scaling works compared with a full AOGCM is both
important and of considerable interest to me (and Ben Santer). It is
something we have looked at in the past, cursorily, and which we were
planning to investigate more fully with the suite of PCM runs that we
have here. There are some tricky issues that need to be addressed.
So, perhaps we should pool our intellectual, modelling and data
resources?
Anyhow, check out the attached and get back to me with your views.
The 'new and improved version' of MAGICC/SCENGEN should be available in
beta-test form in about a month. It will have around 30 models in its
data base, and it does a lot of new things that I can tell you about
later.
Tom.

Tom,
Talked to Tim re the SD field. Can you read the following (J. Climate
10, 2xxx xxxx xxxx)
before you come so you know how Tim infilled the SD field ? HadCM2 data
was used.
This would seem to bias any model validation to this model. Also it would
seem odd to
validate any model in a region where there is no data - in a region that
had to be infilled.
I can see that global fields make things simpler, but they will need
to constructed in
the best possible way. In 1997 we thought the best way was to use a
model, but our aim
then was different from yours.
Cheers

Subject: Re: paleo data
No worries, I can wait till next week!
It would be great to hear from you next week particularly if you
feel I have overlooked something, I am planning to submit a little
GRL paper on the detection results based on paleodata soon, and so a warning
if I am doing something wrong would be great.
Its not surprising that the detection results are stable, since other than volcanic
forcing is mainly driven by the low-f component anyway.
But it looks to me like the volcanic response is not smaller or even a bit larger in the
annual JGR data (except for one real real big peak in
the 1998 data).
Greetings, have a good weekend and good luck for Keith's back
Gabi
Gabi,
I have printed the files, but I do not know the answer. Keith is off today with a
bad back -
seeing a chiropractor. I need to talk to him before we can reply. I will be away
Mon/Tues
next week, so we will not be able to reply until later next week.

Dear Keith and Phil,
I checked and found that we did indeed use the JGR 2001 data (by reloading them
from your JGR data file). I also got the
1998 data from the volcano paper, and did some checking. My detection results
appear quite unimpressed by if I filter the 2001 data to focus on lower
frequencies or not (the estimated amplitudes of solar, volcanic and ghg signals
are virtually identical, volcanism gets a bit tougher to detect if you remove
the high-frequency component).
Then I redid the Epoch analysis comparing the
response of your data old and new to volcanism, and find somewhat bigger volcanic
signals on average (using 50 eruptions between 1400 and 1940) in the
JGR paper record. I high-passed both datasets and get somewhat more variability
in the JGR record, not the 1998 record.
I am wondering is there something I am overlooking?
I append a figure of the high-passed (var > ca 10 yrs removed) records,
and the volcanic response in both datasets (averaging years xxx xxxx xxxxafter the eruption,
and removing the best-estimate solar and ghg signal before the analysis).
The analysis omits years with another volcanic eruption within the 20 yrs.
I also append one version of the figure where the upper 95%ile of the ghg signal (which
appears underestimated in Briffa 98 data) is removed rather than the
best estimate, in that case, the volcanic signals in both data appear nearly
identical.
Greetings, and please let me know if I am doing something wrong with your data!
Also, what is the best reference to a discussion on the difference between both
datasets?
Thanks in advance
Gabi
Dear Tom
after a little detective work we have deduced that the data sent to you constitute a
version of Northern Hemisphere Land temperatures (april- sept) produced by PCA
regression using regional average density chronologies (ie the JGR paper you refereed I
believe). It is true that high frequency component is not in my opinion optimal in
describing the relative magnitude of extreme inter-annual extremes. This is to do with
the unpredictable weighting ascribed to certain areas (tree-density series) in the
averaging of the original raw data ( this is boring and I won't go into it unless you
really want me to). Te relative differences in year-to-year values are likely better
represented in the N.Hemisphere series produced by averaging regional series produced
using a different approach in which the initial data are high-pass filtered and then
merged in a more straight forward way. This is more equivalent to the series on volcanic
signals described in our Nature paper, though the low-frequency component in this series
is definitely not represented. There is another series , that one could consider a good
compromise . That is a composite of the Age-Banding approach (JGR) low-frequency
variance added to the earlier (Nature) high-frequency component. We did this for Figure
6 in the JGR paper , but did not provide the data on our web site I now realize. However
this composite series is VERY highly correlated with the "better" high frequency data -
see the correlations (Table 1 and related text in
[1]http://www.cru.uea.ac.uk/cru/people/briffa/jgr2001/Briffa2001.pdf
There are many possible ways of producing a "Northern Hemisphere" average , involving
different prior regionalisation and secondary weighting (in space and through time) of
the constituent series) . Non can be considered "correct". If you would like us to dig
out the composite series or discuss specific aspects of the logic or uncertainties
associated with the different large averages let me know. Perhaps it would be better to
discuss this on the phone? As for longer series , we can provide the 2000 year
N.Eurasian data (a composite of ring width chronologies in N.Sweden, The Yamal
peninsula, and Taimyr ) . I will soon be able to provide a 4000-year version , that is
now being worked on.
or a similar Northern tree-ring chronology incorporating more data eg see
[2]http://www.cru.uea.ac.uk/cru/people/briffa/qsr1999/
We do not have the bristlecone data - but they are available I presume from the
International Tree-Ring Data bank , part of the NGDC holdings?

Hi Phil,
thanks for all your help on the bams paper
DOE is being exceedingly slow in processing the paperwork for our new round - I will
keep you posted.
I am also wondering whether we can get some data from you:
Gabi is comparing our 2d ebm run with the briffa et al 2001 jgr time series in order to
compare the model prediction of - I think you mentioned at one point something to the
effect that, although this series is good for estimating low resolution temperature
variability, it may dampen high frequency variability. if my memory is correct in this
case, would you please send gabi the record you consider best for comparing with the
model predicted interannual response to volcanic eruptions?
on another matter we are extending our runs back in time - I have now compiled a record
of global volcanism back to 4000 BP for both hemispheres - extended back to 8000 BP for
30-90N. we are therefore trying to compile paleo records older than AD 1000 to at least
get some reconstruction we can compare with.
I seem to recall that Keith or you may have published some longer reconstructionn but
cannot recall where it is? if so, would you be so kind as to send it to me? also I am
trying to find a long record from the eastern California for the bristlecone pine - for
some reason I am having difficulty finding one. if you have a long record - even going
back beyond 2000 BP, it would be very much appreciated.
thanks for any help you can give us on this and best wishes, Tom

Dear Forumites -- Since I am neither a dendrochronologist nor a tree physiologist, I have a
different take on this little brushfire we have going. Ideally, tree phys people should be
producing information (among other things) that dendrochronologists find useful. And
dendrochronologists should use the information within its limits and with enough
understanding to get it right. I don't think either of those things is occurring with as
much frequency as we would all like. I can understand Rod's annoyance at the massaging of
numerical data that dendrochronologists do. I am basically a non-mathematical biologist
mystified by such stuff, and I prefer handling measurements to deriving indices, or
whatever. When I run up against such derived data, I generally turn skeptical, because I
cannot verify the results from my own experience or intuition. On the other hand, when I
read papers by cambial physiologists like Rod I also get annoyed. That's because my biology
wants to integrate upwards, and all I get from cambial labs is biochemistry. So I'm in the
middle, where it gets lonely. I try not to get mad at anybody, though I do wish I didn't
find myself alone on the margins.
I find it frustrating that some dendrochronologists stubbornly see tree ring
characteristics as being affected by climate. They are not. They are affected by cambial
activity. Cambial activity is affected by internalities of tree behavior, mainly hormonal
and nutrient fluxes in the crown. Those things are largely influenced by climatic factors.
So there is quite a bit of slack between the climatic factor and the ring characteristic.
Is this just negligible static? I doubt it. I see this as an oversight by
dendrochronologists that weakens their credibility a tad among those knowledgable about
tree growth. I also have a quarrel with the dogma of dendrochology that the cambium changes
as the tree becomes senescent. I know of no data that trees senesce -- that is, that they
undergo changes due solely to aging. This started as forestry dogma, and was accepted by
tree-ringers, who then corrected for it. I'm practically the only one who has
systematically looked for evidence of senescence (with a Ph.D. student), and we could not
find any in young to ancient bristlecones. But tree physiologists do not generally look at
such issues because they have become progressively more reductionist. Nor do they try to
produce a theory of tree growth based, as it must be, on evolutionary theory. Such a theory
would be simple and general, and it would allow tree-ringers to approach rings with more
sympathy and understanding. That might not get you further, but it would improve your
character, I'm certain. And it would put all that assorted mishmash of tree phys data that
have accumulated since 19th century Germany into a context at last, and maybe liberate the
minds of all those tense physiologists out there with their ever-increasing inventories of
electronic sensors and analyzers. The world would be a better place with more people having
fun in the woods. ---Ronald M. Lanner

Dear Professor Savidge, Hal Fritts's comments were, as always,
to the point and gracious. I
have much less patience with your ignorance and arrogance. The
sampling and statistical procedures involved in the production of a
cross-dated chronology are of course quite different to those used in a
randomised experiment, but they are none-the-less logical,
rigorous, science. We have been through all those arguments so many
times - you are wasting everyone's time.

Dear Keith,
Do not be embarassed. This situation is very humorous and I am very
glad to smile. It happens.
Thank you very much for your time series.
I would like to analyse specta characteristics of summer temperatures ( your
series) and winter temperature series using Dansgaard's time series for
the same period ( since 550s). It seems to me the temperature data of Arctic basin is
the
most pronounced indices illustrating of long term climate oscillations.

I am very embarrassed as I have just realized I sent the data (a couple of weeks ago at

polar Urals data. I now attach the file with the Nature temperature reconstruction.
First number is the number of values , then subsequent lines contain the date in the
first column (years AD) and the anomalies in the second (as described in the paper).
Sorry!!!!!!!!!!!!!!!!!!!

I am Leonid Klyashtorin from Federal Institute for Fisheries and
Oceanography (VNIRO),Moscow,Russia.
The last 6 monthes I was National Research Council Senior
Associate and worked as Visiting Scientist in the
Pacific Fisheries Environmental Laboratory (PFEL),
NOAA, National Marine Fisheries Service,
Monterey , CA on the item "Climate and Fisheries".
My paper "Climate change and long -term fluctuations of commercial
catches:the possibility of forecasting" published recently as a separate
broshure, FAO Fisheries Technical Paper No 410,
pp 86, 2001, and is rather popular among fisheries specialists.
It gives insight of world major fisheries dynamics and contains
forecast to the next xxx xxxx xxxxyears. ( the Abstract is attached, PDF file of
all paper also is available)
I have read of your and T. Osborn very interesting and so useful paper
"Blowing Hot asnd Cold.." in Science, v.295.,2002.
Your results clearly shows that main conception
of IPCC experts about unicity of Global Warming events in
20-century is erroneous and now the additional data appear on the natural
long term cyclic climate change at least for the last 2000 years .
My work on the "Climate - Fisheries" connected with questions of Climate
Change and ,naturely, touches of Global Warming Problem.
Me and my colleague from Institute of Physics of the Earth of Russian
Academie of Science recently submitted our paper "On the coherence
between dynamics of the world fuel consumption and global temperature
anomaly". in the International Journal " Natrural Hazards" .
The paper is now under reviewing. (The Abstract is attached.)
Now me and a few my collegues from US are in process of writiing
book dedicated of Climate- Fisheries problem and we would like use
the data on the tree -rings anlysis showing cyclic character of
long-term climate changes.
I will be very grateful to you for receiving
from you ( if possible) the time series of annual reconstructed
temperature anomaly from Figure (Esper02) and address of website,
where these data are available.
Thank you in

Subject: UK Research Office - FP6 Proposal Writing for Researchers
Date: Tue, 26 Nov 2002 18:34:49 +0000
Cc: j.darch@xxxxxxxxx.xxx
Dear all
I went to this meeting in London yesterday - which was useful. Julie will photocopy my
notes/the overheads for you some time this week (if she doesnt have time, I'll do it when I
get back next week). In the meantime, here are my main impressions/thoughts from the
meeting. (Incidentally, Alex Haxeltine was due to go from UEA, but didnt turn up. Not sure
who the other UEA people were! There was no list of participants.) Maybe we should get
together (next week some time?) once you've had chance to look at some of this.
The Commission (EC) seems to be favouring smaller projects, e.g., typically 10 million
Euro. Though it is up to proposers to define the necessary 'critical mass'.
UKRO seem quite wary of Networks of Excellence (NoE), e.g., warning of potential conflicts
of interest with institutions. As with projects, smaller size seems to be in favour. An
UKRO analysis suggests an NoE of xxx xxxx xxxxresearchers would maximise the amount of money
received per researcher.
Research activities can now be funded in NoE (the EC has changed its mind on this in the
last month), but only if focused on integration.
The EC wont be proposing indicators of integration for NoE - the proposals should explain
how this will be 'measured'.
Consortium quality seems to be an important concern for the EC, i.e., having the right
people for the job and ensuring everyone has a clear role. In our rush to get a 'critical
mass', I'm concerned that the GENIE consortium may appear too much as 'all our friends'.
One possible strategy which UKRO seemed to think quite good for people, would be to put in
a proposal from 6-8 key partners, indicating for which activities additional partners will
be brought in at appropriate points. The EC will be providing formal procedures for these
'internal project' calls.
It is unlikely that the new online proposal preparation tool will be ready for the first
call, but electronic submission (on CD) should be possible. Any paper submissions will be
scanned.
Evaluation will be by electronic means initially, with possibility of proposers (and
evaluators?) being invited to hearings in Brussels prior to panel meetings.
No signatures are required for the proposals (though a password/username will be required
by co-ordinators to access the online system). Some institutions/consortia are apparently
drawing up pre-consortia agreements or letters of intent/memorandum of understanding.
The guide for proposers is currently only in very rough draft.
There will be a second 'EOI' type exercise at the end of 2003/early 2004. This could lead
to changes in the indicative themes for 2004.
UKRO is not keen on UK institutions using consultants for project management - we should be
building our own capacity.
Proposals should be written for the informed lay person. It is best if they are not
obviously written by one person - better to show joint effort/co-ordination at an early
stage.
Redundancy costs (i.e., costs of implementing the new fixed-term regulations) can be
included for research staff.
The EC aims to audit all FP6 projects (because there will be fewer of them).
Recognition of the ERA and policy links will be important for the EC. (The ERA includes
references to developing long-term careers for research staff and increasing the
involvement of women - so maybe we should be thinking of some activities to address these
issues.)
IPR will be an important issue in FP6 - need to get expert advice (e.g., what happens if
consortium changes over course of project).
Consortium agreements will be compulsory.
The proposal forms (for IPs anyway) are relatively simple, e.g., only need to cost four
different types of activity.

Dear friends,
I assume many of you have followed the development of the work
programme for FP6, which have been quite dramatic at times for our
field. The end result is not particularly good, and the whole area of
Global Change has been cut by comparuison with FP5. I talked with
Anver Ghazi last week, and what I know stems from this and from the
Nov. 18 version of the work programme.
The will be no opening for climate dynamics in the first call (Dec. 17).
The second call due in June /July with a deadline in October 2003
will include some paleoclimate openings:
- STREPS for novel paleoreconstructions methods (i.e. a few of the
normal projects of previous FPs) - but remember: 75% of funding goes
to New Instruments: Integrated Projects and NoEs).
- Hot spots in the climate system, including the thermohaline
circulation and the Arctic.
Brussels will not issue anything now about the thrird call, but
according to Ghazi they plan to invite for either an NoE or an IP in
climate dynamics with emphasis on past climate change at that point.
Call will be in 2004. But things can change with this call.
Thus we have quite some time to discuss if we shall go forward with
DOCC or go for IP. The overall size of the IPs have been
substantially reduced, so if we try an IP or an NoE either will need
to be more focussed in terms of science and in terms of partnership
than our Expression of interest.
Ceers,
Eystein

Subject: Climate Change Funding in Scotland
Date: Mon, 2 Dec 2002 15:09:xxx xxxx xxxx
Dear John and Mike
It was over two years ago that we first briefly discussed the opportunity to
develop climate change research funding in Scotland using a grant to HEI's
from the Scottish Higher Education Funding Council (SHEFC). My Centre, CECS,
has been successful with such grants in the past. Last year there were no
such grants but the opportunity has now arisen again. The funding is quite
large (0.xxx xxxx xxxx.5 million over up to 4 years). With support from the three
main agencies in Scotland I am keen to develop such a research proposal and
will be entering the internal competition (within the University) shortly.
I am keen to develop a strong link/cooperation with the Tyndall Centre and I
would like to explore ways in which this might be achieved. Last week I
believe that you were busy with your Advisory Board. I would be very keen to
talk with you on the phone about this as soon as possible. Please let me
know if there is a suitable time when I might phone or feel free to contact
me.
Best wishes

Thanks very much Tim,
Your comments are extremely helpful.
I'm open to eliminating the comparison w/ Esper et al --but lets see if there is a
consensus of the group as to what to do here. We're anxiously awaiting comments from the
others...
thanks again,
mike
p.s. Scott can be reached at either U.Va or U.RI email equally well (I believe the former
is forwarded to the latter)..

Dear Scott and Mike,
Over the Christmas break I (finally!) had time to read the RegEM manuscript in detail.
Phil had already read and annotated a copy - so I've added my annotations to that and
will mail it to you today. Mike asked for comments to go to Scott, so please tell me
which address I should use (Rhode Island or Virginia?).
I spoke to Keith and he has partly read it too, and will provide separate comments soon.
Overall, I think the paper is a very nice piece of work and I'm pleased to be involved
with it. The results regarding robustness with respect to proxy data, method, region
and season are definitely good to publish.
Among the many comments annotated on the manuscript, a few are repeated here so that all
authors may respond if they wish:
(1) Given the overwhelming number of values in the Tables, I suggest halving them by
dropping all the CE values (keeping just RE values). As the paper points out, getting
the verification period mean right is rewarded by RE but not by CE. Since we are
interested in changes in the mean, I don't think that's a problem. CE is fine in
addition, but dropping it would provide benefits of reducing manuscript size - and
especially the size of the tables.
(2) The "mixed-hybrid" approach sounds dubious to me - more justification/explanation of
why it is needed (and hence why it captures more variance than the simpler splitting
into high- and low-frequency components method).
(3) It is not clear to me that the paragraph and figure on the comparison with Esper et
al. are either correct or necessary. They also are problematic because it would appear
that we (Briffa & Osborn) were contradicting our earlier paper when in fact we aren't.
The paper is already long and to remove these parts would therefore be helpful anyway.
The comparison with Esper et al. is important - but much better dealt with in a separate
paper where it could be developed in more detail and with more room to explain the
approach and its implications.
(4) I still hope to write up some more detailed comparisons of the reconstructions using
just the MXD data but different methods and will let Mike/Scott know my plans on this
soon.
Happy new year to you all.

<x-flowed>
Tim,
As promised some comments on the paper.
General: It is very good, just what is needed and puts the last 4 years of
debate into the right context.
General: why consistently 'climate changes' rather than the more usual
'climate change'?
Abstract, line 10: why only quote as high as 0.99 and not the lowest
correlation (which actually is more to the point - it is still very good
after the 2020s, even for precip).
Abstract, lines 12-13: as worded this does not quite follow, although I see
from later that the ellipses used are at 95% confidence. Just because they
fall outside natural variability does not *in itself* prove they are stat. sig.
p.2, lines xxx xxxx xxxx(and also several places on p.4): impacts are mentioned,
but nothing said about adaptation. It is really adaptation
actions/decisions that are crucial, impacts are only one way to get
there. Alter the focus.
p.2, line -10: add 'necessarily' between 'not' and 'be'. AOGCMs may
actually do not so bad a job on occasions about climate change (relative
changes for example), so don't completely dismiss this one.
p.5, section 2: general point: there is no list or table or statement about
exactly what these 17 experiments are. The models are listed, but not the
experiments. e.g. which SRES scenarios did which modelling group and how
many ensembles? For the lay person this is not obvious.
p.7, top line: you should perhaps make the point that simple bias indices
such as these may partly be explained by elevation offsets (model height
vs. real height). It is to my mind a mitigating factor than can work in a
model's favour (not always). It should be mentioned, because the biases
may not be due to just dumb models, but due to simple resolution issues
that can be adjusted easily. A similar point perhaps applies in the next
para. about ocean/land boundaries. OK, you could say this just shows how
bad models are, but it perhaps gives people a poorer view of the model
physics and credibility than is truly needed. Another point to mention in
this para about precip. is the obvious point about decadal natural
variability. It's a tall order to expect the models to get the 1xxx xxxx xxxx
monthly mean precip. exactly right, owing to internal variability. Indeed,
give such variability can be plus/minus 10-20% or more it would be
astonishing if they matched. Be generous to models I say.
p.9, middle - interesting point about ECHAM4 and NCAR masks!!
p.15, para 2: didn't you have A1FI available from Hadley? Surely it could
have been used to test this? Last sentence in this para: why 'evidently
conform'?
p.16, last line: interesting point here: if you claim the pattern-scaling
didn't work for the 2020s because of nat var (S/N ratios) then why actually
should we go with the raw model results anyway - certainly if it is the
signal we are interested in (and not the noise), it suggests the raw 2020s
models results are misleading us! This is a rather circular argument I
realise but the bottom line point again comes back to S/N ratios and the
role of nat decadal variabiliy, esp. for precip. Are we going to recommend
adaptations to noise or to signals - and why?
p.17, middle para: what about mentioning climate sensitivity here? I know
its out of vogue now, but PCM and NIES differences are explained by overall
model sensitivity aren't they.
p.17, para 4: this point about where agreement occurs between models is
important. Some people - I heard Wigley do it recently - write models off
at regional scales re. precip changes because they all disagree. They do
for some regions, but not all and where we think we have physical grounds
to accept agreement as legit. (e.g. UK; cf. UKCIP02 scenario metholody)
then we should be confident to say so.
p.17, line -7: why use 'forecasting' here? Could confuse some people. The
old argument about terms I guess. And again top line on p.18 is dangerous
- we can "predict" nat. variability in a stochastic sense using
ensembles. Change the wording.
p.18, line 9: not only are they difficult to forsee, they are simply
unforseeable to a significant extent because it is we who determine them; I
prefer to make the distinction between different types of prediction
problem more explicit.
p.18, lines 19-20: I don't like the use of 'truth' and 'precise' here. It
implies a strong natural science view prediction and the competence of
science (modellers!) which I think should be softened.
p.18, para 4: the inter-model differences bit being as large as the
inter-scenario differences. Again at least mention the role of nat var
here - some of these inter-model differences *must* be due to nat var, not
simply models not able to agree with each other.
p.19, para 1: I think the stabilisation case should be mentioned
here. What about pattern-scaling stab scenarios? As I hear it from DEFRA
and Hadley here in UK this was a big issue at the TGCIA meeting. Make a
comment at least; I think in principle p-scaling is probably OK (within
some limits) even here. I think you should make reference to some of Tim
Mitchell's work here (and/or elsewhere) since he has looked at some of
these things too. His thesis or his CC paper perhaps.
And finally, w/o sounding as self-serving as Tom Wigley, it would be nice
if you could reference (perhaps in section 3.3) the Hulme/Brown (1998)
paper in CR which was the first time I published scatter plots in this form
for GCMs results - and possible the first time this form of presentation
had been used anywhere (but I stand corrected of course; maybe I simply
picked it up from someone else).
So there it is: a great piece of work and a good write up. I don't know
Kimmo but pass on my congratulations to him. I'll look out for it on the
web site.
Best wishes,
Mike

Dear Ulrich,
That's fine--you can go ahead and use it. But I have to issue a number of caveats first.
This is a version we gave Tim Osborne when he was visiting here, and since Tim hasn't used
it, and we haven't compared results from that code w/ our published results, I can't vouch
for it--it may or may not be the exact same version we ultimately used, and it may or may
not run properly on platforms other than the one I was using (Sun running ultrix). Scott
Rutherford (whom I've cc'd on this email) has worked with the code more frequently.
The code is not very user friendly unfortunately. For example, the determination of the
optimal subset of PCs to retain is based on application of the criterion described in our
paper, which involves running the code many times w/ different choices. So the "iterative"
process has to be performed by brute force.
The method, as outlined, is quite straightforward and others have implemented it
themselves. SO you might prefer to code it yourself. That would be my suggestion. But you
are, of course, free to use our code.
That having been said, we have essentially abandoned that method now in favor of a
somewhat more sophisticated version of the approach, which makes use of the RegEM method
for imputing missing values of a field described by Schneider (J. Climate, 2000).
Some initial results are described here:
Mann, M.E., Rutherford, S., Climate Reconstruction Using 'Pseudoproxies', Geophysical
Research Letters, 29 (10), 1501, doi: 10.1029/2001GL014554
[1]ftp://holocene.evsc.virginia.edu/pub/mann/Pseudoproxy02.[2]pdf
and in a paper in press in Journal of Climate.
Rutherford, S., Mann, M.E., Delworth, T.L., Stouffer, R., The Performance of
Covariance-Based Methods of Climate Field Reconstruction Under Stationary and Nonstationary
Forcing, J. Climate, in press, 2003.
(I don't have the preprint--Scott Rutherford can provide you with one however).
In our view, this is a preferable approach on a number of levels, though the results
obtained are generally quite similar.
I will be in Nice, and looking forward to seeing you there,
Mike

Dear Irina,
The code we used in Mann/Bradley/Hughes 1998 was not changed or "improved", but there may
be different versions of the code floating around, and in a previous email to Uli Cubasch,
I indicated that I was not sure the version you have (from Tim Osborn), is identifical to
the version we used in our original paper (it would require some work on my part to insure
it gives precisely the same results, and I don't have the time to do that). I suspect,
however, that the code is the same as the one we used in our paper and any differences, if
they exist, should be minor (as long as the code compiles and runs correctly on the
platform you have--the possible platform-dependence of fortran is a potential cause for
concern here).
Numerous people have coded up our method independently, including Ed Zorita, w/ whom I
believe your group has a close collaboration, and my graduate student Zhang has
successfully coded this up independently in Matlab (its a short script, which didn't take
Zhang long to write anyway). I'm copying this message to Zhang, so that he can provide you
with his matlab version of the code if you are interested. Because Zhang's version is in
Matlab, it should run correctly, independently of the particular platform (an advantage
over the fortran code) [As an aside, on a pedagogical note, I would still encourage you to
code this up yourself].
As I indicated in a previous email to Uli, the selection of the optimal subset of EOFS to
retain is not automated in the code, and you need to do that yourself...The methodology we
used is described in detail in our publications.
We have tested this method against the approach our group now uses for climate field
reconstruction (Schneider RegEM approach), and find that the results are similar, but the
cross-validation statistics improve slightly w/ the RegEM approach, which we now favor and
use in place of the old, Mann et al approach.
Details of this latter approach are described in these two manuscripts (as well as the
original paper by Schneider referenced within):
Mann, M.E., Rutherford, S., Climate Reconstruction Using 'Pseudoproxies', Geophysical

At the SOAP's start-up meeting it was proposed to use your multiproxy

simulations and proxydata.
Because your method was essential improved since 1998 I would like to know if
you kann provide us with your program code.
We could try to code your approach ourselves, but we do not know if this kind

I apologise for my mistakes in this letter.

Thanks Phil,
(Tom: Congrats again!)
The Soon & Baliunas paper couldn't have cleared a 'legitimate' peer review process
anywhere. That leaves only one possibility--that the peer-review process at Climate
Research has been hijacked by a few skeptics on the editorial board. And it isn't just De
Frietas, unfortunately I think this group also includes a member of my own department...
The skeptics appear to have staged a 'coup' at "Climate Research" (it was a mediocre
journal to begin with, but now its a mediocre journal with a definite 'purpose').
Folks might want to check out the editors and review editors:
[1]http://www.int-res.com/journals/cr/crEditors.html
In fact, Mike McCracken first pointed out this article to me, and he and I have discussed
this a bit. I've cc'd Mike in on this as well, and I've included Peck too. I told Mike that
I believed our only choice was to ignore this paper. They've already achieved what they
wanted--the claim of a peer-reviewed paper. There is nothing we can do about that now, but
the last thing we want to do is bring attention to this paper, which will be ignored by the
community on the whole...
It is pretty clear that thee skeptics here have staged a bit of a coup, even in the
presence of a number of reasonable folks on the editorial board (Whetton, Goodess, ...). My
guess is that Von Storch is actually with them (frankly, he's an odd individual, and I'm
not sure he isn't himself somewhat of a skeptic himself), and without Von Storch on their
side, they would have a very forceful personality promoting their new vision.
There have been several papers by Pat Michaels, as well as the Soon & Baliunas paper, that
couldn't get published in a reputable journal.
This was the danger of always criticising the skeptics for not publishing in the
"peer-reviewed literature". Obviously, they found a solution to that--take over a journal!
So what do we do about this? I think we have to stop considering "Climate Research" as a
legitimate peer-reviewed journal. Perhaps we should encourage our colleagues in the climate
research community to no longer submit to, or cite papers in, this journal. We would also
need to consider what we tell or request of our more reasonable colleagues who currently
sit on the editorial board...
What do others think?

Dear All,
Apologies for sending this again. I was expecting a stack of emails this morning
in
response, but I inadvertently left Mike off (mistake in pasting) and picked up Tom's
old
address. Tom is busy though with another offspring !
I looked briefly at the paper last night and it is appalling - worst word I can
think of today
without the mood pepper appearing on the email ! I'll have time to read more at the
weekend
as I'm coming to the US for the DoE CCPP meeting at Charleston. Added Ed, Peck and
Keith A.
onto this list as well. I would like to have time to rise to the bait, but I have so
much else on at
the moment. As a few of us will be at the EGS/AGU meet in Nice, we should consider what
to do there.
The phrasing of the questions at the start of the paper determine the answer they
get. They
have no idea what multiproxy averaging does. By their logic, I could argue 1998 wasn't
the
warmest year globally, because it wasn't the warmest everywhere. With their LIA being
1300-
1900 and their MWP xxx xxxx xxxx, there appears (at my quick first reading) no discussion of
synchroneity of the cool/warm periods. Even with the instrumental record, the early and
late
20th century warming periods are only significant locally at between 10-20% of grid
boxes.
Writing this I am becoming more convinced we should do something - even if this is
just
to state once and for all what we mean by the LIA and MWP. I think the skeptics will
use
this paper to their own ends and it will set paleo back a number of years if it goes
unchallenged.
I will be emailing the journal to tell them I'm having nothing more to do with it
until they
rid themselves of this troublesome editor. A CRU person is on the editorial board, but
papers
get dealt with by the editor assigned by Hans von Storch.
Cheers

Dear all,
Tim Osborn has just come across this. Best to ignore probably, so don't let it
spoil your
day. I've not looked at it yet. It results from this journal having a number of
editors. The
responsible one for this is a well-known skeptic in NZ. He has let a few papers
through by
Michaels and Gray in the past. I've had words with Hans von Storch about this, but got
nowhere.
Another thing to discuss in Nice !
Cheers

Dear All,
Apologies for sending this again. I was expecting a stack of emails
this morning in
response, but I inadvertently left Mike off (mistake in pasting) and
picked up Tom's old
address. Tom is busy though with another offspring !
I looked briefly at the paper last night and it is appalling - worst
word I can think of today
without the mood pepper appearing on the email ! I'll have time to read
more at the weekend
as I'm coming to the US for the DoE CCPP meeting at Charleston. Added Ed,
Peck and Keith A.
onto this list as well. I would like to have time to rise to the bait,
but I have so much else on at
the moment. As a few of us will be at the EGS/AGU meet in Nice, we should
consider what
to do there.
The phrasing of the questions at the start of the paper determine the
answer they get. They
have no idea what multiproxy averaging does. By their logic, I could
argue 1998 wasn't the
warmest year globally, because it wasn't the warmest everywhere. With
their LIA being 1300-
1900 and their MWP xxx xxxx xxxx, there appears (at my quick first reading) no
discussion of
synchroneity of the cool/warm periods. Even with the instrumental record,
the early and late
20th century warming periods are only significant locally at between
10-20% of grid boxes.
Writing this I am becoming more convinced we should do something -
even if this is just
to state once and for all what we mean by the LIA and MWP. I think the
skeptics will use
this paper to their own ends and it will set paleo back a number of years
if it goes
unchallenged.
I will be emailing the journal to tell them I'm having nothing more
to do with it until they
rid themselves of this troublesome editor. A CRU person is on the
editorial board, but papers
get dealt with by the editor assigned by Hans von Storch.
Cheers
Phil
Dear all,
Tim Osborn has just come across this. Best to ignore probably, so
don't let it spoil your
day. I've not looked at it yet. It results from this journal having a
number of editors. The
responsible one for this is a well-known skeptic in NZ. He has let a few
papers through by
Michaels and Gray in the past. I've had words with Hans von Storch about
this, but got nowhere.
Another thing to discuss in Nice !
Cheers
Phil

Dear All,
I like Phil's suggestion. I think such a piece would do a lot of good for the field. When
something as full of half-truths/mis-truths as the S&B piece is put forth, it would be
very useful to have a peer-reviewed review like this, which we all have endorsed through
co-authorship, to point to in response. This way, when we get the inevitable "so what do
you have to say about this" from our colleagues, we already have a self-contained, thorough
rejoinder to point to. I'm sure we won't all agree on every detail, but there is enough
commonality in our views on the big issues to make this worthwhile.
Perhaps Phil can go ahead and contact the editorial board at "Reviews of Geophysics" and
see if they're interested. If so, Phil and I (and anyone else interested) could take the
lead with this, and then we can entrain everyone else in as we proceed with a draft, etc.

p.s. Keith: I hope you're feeling well, and that your recovery proceeds quickly!

but how do we go about not letting it get buried somewhere. Can we not address the
misconceptions by finally coming up with definitive dates for the LIA and MWP and
redefining what we think the terms really mean? With all of us and more on the paper,
it should
carry a lot of weight. In a way we will be setting the agenda for what should be being
done
over the next few years.
We do want a reputable journal but is The Holocene the right vehicle. It is
probably the
best of its class of journals out there. Mike and I were asked to write an article for
the EGS
journal of Surveys of Geophysics. You've not heard of this - few have, so we declined.
However,
it got me thinking that we could try for Reviews of Geophysics. Need to contact the
editorial
board to see if this might be possible. Just a thought, but it certainly has a high
profile.
What we want to write is NOT the scholarly review a la Jean Grove (bless her soul)
that
just reviews but doesn't come to anything firm. We want a critical review that enables
agendas to be set. Ray's recent multi-authored piece goes a lot of the way so we need
to build on this.
Cheers

HI Malcolm,
Thanks for the feedback--I largely concur. I do, though, think there is a particular
problem with "Climate Research". This is where my colleague Pat Michaels now publishes
exclusively, and his two closest colleagues are on the editorial board and review editor
board. So I promise you, we'll see more of this there, and I personally think there *is*
a bigger problem with the "messenger" in this case...
But the Soon and Baliunas paper is its own, separate issue too. I too like Tom's latter
idea, of a more hefty multi-authored piece in an appropriate journal (Paleoceanography?
Holocene?) that seeks to correct a number of misconceptions out there, perhaps using
Baliunas and Soon as a case study ('poster child'?), but taking on a slightly greater
territory too.
Question is, who would take the lead role. I *know* we're all very busy,
mike

I'm with Tom on this. In a way it comes back to a rant of mine
to which some of you have already been victim. The general
point is that there are two arms of climatology:
neoclimatology - what you do based on instrumental records
and direct, systematic observations in networks - all set in a
very Late Holocene/Anthropocene time with hourly to decadal
interests.
paleoclimatology - stuff from rocks, etc., where major changes
in the Earth system, including its climate, associated with
major changes in boundary conditions, may be detected by
examination of one or a handful of paleo records.
Between these two is what we do - "mesoclimatology" -
dealing with many of the same phenomena as neoclimatology,
using documentary and natural archives to look at phenomena
on interannual to millennial time scales. Given relatively small
changes in boundary conditions (until the last couple of
centuries), mesoclimatology has to work in a way that is very
similar to neoclimatology. Most notably, it depends on heavily
replicated networks of precisely dated records capable of
being either calibrated, or whose relationship to climate may
be modeled accuarately and precisely.
Because this distinction is not recognized by many (e.g.
Sonnechkin, Broecker, Karlen) we see an accumulation of
misguided attempts at describing the climate of recent
millennia. It would be better to head this off in general, rather
than draw attention to a bad paper. After all, as Tom rightly
says, we could all nominate really bad papers that have been
published in journals of outstanding reputation (although there
could well be differences between our lists).
End of rant, Cheers, Malcolm

Phil et al,
I suggest either BAMS or Eos - the latter would probably be better because it is shorter,
quicker, has a wide distribution, and all the points that need to be made have been made
before.
rather than dwelling on Soon and Baliunas I think the message should be pointedly made
against all of the standard claptrap being dredged up.
I suggest two figures- one on time series and another showing the spatial array of
temperatures at one point in the Middle Ages. I produced a few of those for the Ambio
paper but already have one ready for the Greenland settlement period xxx xxxx xxxxshowing the
regional nature of the warmth in that figure. we could add a few new sites to it, but if
people think otherwise we could of course go in some other direction.
rather than getting into the delicate question of which paleo reconstruction to use I
suggest that we show a time series that is an eof of the different reconstructions - one
that emphasizes the commonality of the message.
Tom

<x-rich>Dear All,
First, I'd be willing to handle the data and the plotting/mapping.
Second, regarding Mike's suggestions, if we use different reference
periods for the reconstructions and the models we need to be extremely
careful about the differences. Not having seen what this will look
like, I suggest that we start with the same instrumental reference
period for both (1xxx xxxx xxxx). If you are willing to send me your series
please send the raw (i.e. unfiltered) series. That way I can treat
them all the same. We can then decide how we want to display the
results.
Finally, Tom's suggestion of Eos struck me as a great way to get a
short, pointed story out to the most people (though I have no feel for
the international distribution). My sense (being relatively new to
this field compared to everyone else) is that within the neo- and
mesoclimate research community there is a (relatively small?) group of
people who don't or won't "get it" and there is nothing we can do
about them aside from continuing to publish quality work in quality
journals (or calling in a Mafia hit). Those (e.g. us) who are
engrossed in the issues and are aware of all the literature should be
able to distinguish between well done and poor work. Should then the
intent of this proposed contribution be to education those who are not
directly involved in MWP/LIA issues including those both on the
perifery of the issue as well as those outside? If so, then the issue
that Phil raised about not letting it get buried is significant and I
think Eos is a great way to get people to see it.

Scott

<excerpt>p.s. The idea of both a representative time-slice spatial
plot emphasizing the spatial variability of e.g. the MWP or LIA, and
an EOF analysis of all the records is a great idea. I'd like to
suggest a small modification of the latter:
I would suggest we show 2 curves, representing the 1st PC of two
different groups, one of empirical reconstructions, the other of model
simulations, rather than just one in the time plot.
Group #1 could include:
1) Crowley & Lowery
2) Mann et al 1999
3) Bradley and Jones 1995
4) Jones et al, 1998
5) Briffa et al 200X? [Keith/Tim to provide their preferred MXD
reconstruction]
6) Esper et al [yes, no?--one series that differs from the others
won't make much of a difference]
I would suggest we scale the resulting PC to the CRU 1xxx xxxx xxxxannual
Northern Hemisphere mean instrumental record, which should overlap w/
all of the series, and which pre-dates the MXD decline issue...
Group #2 would include various model simulations using different
forcings, and with slightly different sensitivities. This could
include 6 or so simulation results:
1) 3 series from Crowley (2000) [based on different solar/volcanic
reconstructions],
2) 2 series from Gerber et al (Bern modeling group result) [based on
different assumed sensitivities]
1) Bauer et al series (Claussen group EMIC result) [includes 19th/20th
century land use changes as a forcing].
I would suggest that the model's 20th century mean is aligned with the
20th century instrumental N.Hem mean for comparison (since this is
when we know the forcings best).
I'd like to nominate Scott R. as the collector of the time series and
the performer of the EOF analyses, scaling, and plotting, since Scott
already has many of the series and many of the appropriate analysis
and plotting tools set up to do this.
We could each send our preferred versions of our respective time
series to Scott as an ascii attachment, etc.

Thanks Tom,
Either would be good, but Eos is an especially good idea. Both Ellen
M-T and Keith Alverson are on the editorial board there, so I think
there would be some receptiveness to such a submission.t
I see this as complementary to other pieces that we have written or
are currently writing (e.g. a review that Ray, Malcolm, and Henry Diaz
are doing for Science on the MWP) and this should proceed entirely
independently of that.
If there is group interest in taking this tack, I'd be happy to
contact Ellen/Keith about the potential interest in Eos, or I'd be
happy to let Tom or Phil to take the lead too...

Dear All,
I agree with all the points being made and the multi-authored
article would be a good idea,
but how do we go about not letting it get buried somewhere. Can we
not address the
misconceptions by finally coming up with definitive dates for the LIA
and MWP and
redefining what we think the terms really mean? With all of us and
more on the paper, it should
carry a lot of weight. In a way we will be setting the agenda for
what should be being done
over the next few years.
We do want a reputable journal but is The Holocene the right
vehicle. It is probably the
best of its class of journals out there. Mike and I were asked to
write an article for the EGS
journal of Surveys of Geophysics. You've not heard of this - few
have, so we declined. However,
it got me thinking that we could try for Reviews of Geophysics. Need
to contact the editorial
board to see if this might be possible. Just a thought, but it
certainly has a high profile.
What we want to write is NOT the scholarly review a la Jean Grove
(bless her soul) that
just reviews but doesn't come to anything firm. We want a critical
review that enables
agendas to be set. Ray's recent multi-authored piece goes a lot of
the way so we need
to build on this.
Cheers
Phil

HI Malcolm,
Thanks for the feedback--I largely concur. I do, though, think there
is a particular problem with "Climate Research". This is where my
colleague Pat Michaels now publishes exclusively, and his two closest
colleagues are on the editorial board and review editor board. So I
promise you, we'll see more of this there, and I personally think
there *is* a bigger problem with the "messenger" in this case...
But the Soon and Baliunas paper is its own, separate issue too. I too
like Tom's latter idea, of a more hefty multi-authored piece in an
appropriate journal (Paleoceanography? Holocene?) that seeks to
correct a number of misconceptions out there, perhaps using Baliunas
and Soon as a case study ('poster child'?), but taking on a slightly
greater territory too.
Question is, who would take the lead role. I *know* we're all very
busy,

I'm with Tom on this. In a way it comes back to a rant of mine
to which some of you have already been victim. The general
point is that there are two arms of climatology:
neoclimatology - what you do based on instrumental records
and direct, systematic observations in networks - all set in a
very Late Holocene/Anthropocene time with hourly to decadal
interests.
paleoclimatology - stuff from rocks, etc., where major changes
in the Earth system, including its climate, associated with
major changes in boundary conditions, may be detected by
examination of one or a handful of paleo records.
Between these two is what we do - "mesoclimatology" -
dealing with many of the same phenomena as neoclimatology,
using documentary and natural archives to look at phenomena
on interannual to millennial time scales. Given relatively small
changes in boundary conditions (until the last couple of
centuries), mesoclimatology has to work in a way that is very
similar to neoclimatology. Most notably, it depends on heavily
replicated networks of precisely dated records capable of
being either calibrated, or whose relationship to climate may
be modeled accuarately and precisely.
Because this distinction is not recognized by many (e.g.
Sonnechkin, Broecker, Karlen) we see an accumulation of
misguided attempts at describing the climate of recent
millennia. It would be better to head this off in general, rather
than draw attention to a bad paper. After all, as Tom rightly
says, we could all nominate really bad papers that have been
published in journals of outstanding reputation (although there
could well be differences between our lists).
