Personally, I've never subscribed to the AGW theory, primarily because of the work of Dr. Edward Lorenz, who discovered Chaos Theory while trying to get his computer to model the Atmosphere. He established that modeling cannot achieve an accurate prediction of weather for a given date beyond 3 to 5 days in the future. Because of bifurcation of the extrapolations, in which minuscule variances at the level of data errors can cause huge variations in the model output, it is highly unlikely that any computer model, or several such models combined, can predict weather 50 years into the future, as has been claimed by the IPCC. IF they could predict the weather that accurately that far in advance their models could be modified to predict the stock market tomorrow.
Yesterday I downloaded the files hacked from the IPCC website in England (it's at WkiiLeaks) and began reading them. I read the tree ring data and all the comments in them. The yamal tree-ring data is the basis for the "new" and infamous "Hockey Stick" graph supposedly proving that the globe is heating up and can only get hotter if we don't regulate increases in the atmospheric CO2. The previous Hockey Stick graph, by Dr. Mann, was throughly destroyed when it was showed that he cherry picked the data and then grossly manipulated it. The problem was not in showing the data cooking. It was getting ahold of the data, which was not being released, contrary to the peer review process and two centuries of scientific research tradition. You cannot replicate an experiment if they don't archive the data.
Counting the "read.me" the folder contains 84 files, most dated 5/24/96, then many are randomly dated between then and 2/19/99. Then, on 12/31/2008 are three data yamal data files which have been pre-processed for use as source files to tsplot, or some other graphing utility, and a Word DOC file containing a draft of a paper which was going to be or has been published, concerning the yamal tree rings.
[EDIT: I've discovered that the 12/31/2008 date must be the result of a touch command, because the DOC file shows, in the properties, that it was first created in 2002 as part of a GreenLand study.]
Here is it's Abstract:
However, some are questioning if tree-rings really relate to global temperatures or just local temperature, and if there is a relationship is it linear as the IPCC studies state.
Here is an excerpt from 1256760240.txt
The "readme.txt"'s, the "info.txt"s, and looking at the tsplot.apo function which was used to generate the yamal graphs is a revelation. Reading the emails is a total SHOCK! They led me to an article by Steve McIntyer, which discussed the Yamal data and in which he demonstrates how the data was manipulated to produce the hockey stick but when not manipulated produces the cool down which has actually occurred during the last eight years, thus destorying the yamal data hockey stick.
Here is one of the emails that discuss McIntyre's report and question their own data and conclusions. They top-post at the ICPP, so the start is at the bottom and the end is at the top.
They are asking questions among themselves which clearly indicate their "model" does not explain important questions, and they know it! And this is just a few weeks before they go to Copenhagen to help further the agenda of the IPCC by reporting even "more evidence" of GW.
Michael Mann was worried about the BBC not staying in the choir, but in this thread he is busy trying to keep the troops in line.

I have LOTS of emails to read. I started with those written just a couple weeks ago, on 11/14/09. They go back to 1996.
So far, I have read less than a dozen. There are about 1,070 files, each containing a single email or a thread of several emails.
From what I have seen, and the recent page posted by Steve McIntyre at Climate Audit, I can understand why this debacle is being called CRUdGate. CRU is the Climate Research Unit at the University where CRU director Phil Jones is a professor.
Yesterday I downloaded the files hacked from the IPCC website in England (it's at WkiiLeaks) and began reading them. I read the tree ring data and all the comments in them. The yamal tree-ring data is the basis for the "new" and infamous "Hockey Stick" graph supposedly proving that the globe is heating up and can only get hotter if we don't regulate increases in the atmospheric CO2. The previous Hockey Stick graph, by Dr. Mann, was throughly destroyed when it was showed that he cherry picked the data and then grossly manipulated it. The problem was not in showing the data cooking. It was getting ahold of the data, which was not being released, contrary to the peer review process and two centuries of scientific research tradition. You cannot replicate an experiment if they don't archive the data.

Here is it's Abstract:
Abstract. Remains of subfossil Siberian larch trees in the Holocene deposits of the Yamal Peninsula (Western Siberia) have been collected in order to develop a continuous, multi-millennium tree-ring-width chronology. To date, this work has resulted in the construction of an absolute 4000-year (from 2000 BC to 1996 AD) series. From these data, we are able to estimate summer temperature variability in this region on scales. Radiocarbon dating of selected older material shows that the absolute age of the oldest subfossil wood reaches back 9400 years and the dates of the sampled material are generally distributed more or less evenly through time. This demonstrates that it will be possible to develop a tree-ring chronology more than 9 thousand years long. An initial assessment of long-term fluctuations in northern Yamal summer warmth has been realised through the reconstruction of tree-line dynamics using a combination of dendrochronological (absolute) dated material and less precisely (radiocarbon) dated older subfossils.

Dear Professor Briffa, I am pleased to hear that you appear to have recovered
from your recent illness sufficiently to post a response to the controversy
surrounding the use of the Yamal chronology;
([5]http://www.cru.uea.ac.uk/cru/people/briffa/yamal2009/cautious/cautious.htm)
and the chronology itself;
([6]http://www.cru.uea.ac.uk/cru/people/briffa/yamal2009/)
Unfortunately I find your explanations lacking in scientific rigour and I am
more inclined to believe the analysis of McIntyre
([7]http://www.climateaudit.org/?p=7588)
Can I have a straightforward answer to the following questions
1) Are the reconstructions sensitive to the removal of either the Yamal data
and Strip pine bristlecones, either when present singly or in combination?
2) Why these series, when incorporated with white noise as a background, can
still produce a Hockey-Stick shaped graph if they have, as you suggest, a low
individual weighting?
And once you have done this, please do me the courtesy of answering my
initial email.

Subject: Yamal and paleoclimatology
Dear Professor Briffa, my apologies for contacting you directly, particularly
since I hear that you are unwell.
However the recent release of tree ring data by CRU has prompted much
discussion and indeed disquiet about the methodology and conclusions of a
number of key papers by you and co-workers.
As an environmental plant physiologist, I have followed the long debate
starting with Mann et al (1998) and through to Kaufman et al (2009).
As time has progressed I have found myself more concerned with the whole
scientific basis of dendroclimatology. In particular;
1) The appropriateness of the statistical analyses employed
2) The reliance on the same small datasets in these multiple studies
3) The concept of "teleconnection" by which certain trees respond to the
"Global Temperature Field", rather than local climate
4) The assumption that tree ring width and density are related to temperature
in a linear manner.
Whilst I would not describe myself as an expert statistician, I do use
inferential statistics routinely for both research and teaching and find
difficulty in understanding the statistical rationale in these papers.
As a plant physiologist I can say without hesitation that points 3 and 4 do
not agree with the accepted science.
There is a saying that "extraordinary claims require extraordinary proof".
Given the scientific, political and economic importance of these papers,
further detailed explanation is urgently required.
Yours sincerely,
Dr. Don Keiller.

Dear Professor Briffa, my apologies for contacting you directly, particularly
since I hear that you are unwell.
However the recent release of tree ring data by CRU has prompted much
discussion and indeed disquiet about the methodology and conclusions of a
number of key papers by you and co-workers.
As an environmental plant physiologist, I have followed the long debate
starting with Mann et al (1998) and through to Kaufman et al (2009).
As time has progressed I have found myself more concerned with the whole
scientific basis of dendroclimatology. In particular;
1) The appropriateness of the statistical analyses employed
2) The reliance on the same small datasets in these multiple studies
3) The concept of "teleconnection" by which certain trees respond to the
"Global Temperature Field", rather than local climate
4) The assumption that tree ring width and density are related to temperature
in a linear manner.
Whilst I would not describe myself as an expert statistician, I do use
inferential statistics routinely for both research and teaching and find
difficulty in understanding the statistical rationale in these papers.
As a plant physiologist I can say without hesitation that points 3 and 4 do
not agree with the accepted science.
There is a saying that "extraordinary claims require extraordinary proof".
Given the scientific, political and economic importance of these papers,
further detailed explanation is urgently required.
Yours sincerely,
Dr. Don Keiller.
Here is one of the emails that discuss McIntyre's report and question their own data and conclusions. They top-post at the ICPP, so the start is at the bottom and the end is at the top.
They are asking questions among themselves which clearly indicate their "model" does not explain important questions, and they know it! And this is just a few weeks before they go to Copenhagen to help further the agenda of the IPCC by reporting even "more evidence" of GW.
Michael Mann was worried about the BBC not staying in the choir, but in this thread he is busy trying to keep the troops in line.

I have LOTS of emails to read. I started with those written just a couple weeks ago, on 11/14/09. They go back to 1996.
So far, I have read less than a dozen. There are about 1,070 files, each containing a single email or a thread of several emails.
From what I have seen, and the recent page posted by Steve McIntyre at Climate Audit, I can understand why this debacle is being called CRUdGate. CRU is the Climate Research Unit at the University where CRU director Phil Jones is a professor.
