Global warming emails updated

It gets worse.

From the Times -

Astonishingly, what appears, at least at first blush, to have emerged is that (a) the scientists have been manipulating the raw temperature figures to show a relentlessly rising global warming trend; (b) they have consistently refused outsiders access to the raw data; (c) the scientists have been trying to avoid freedom of information requests; and (d) they have been discussing ways to prevent papers by dissenting scientists being published in learned journals.

From the hacked emails are two communications from plant physiologist Dr Don Keiller to Dr Biffra who developed the tree ring "proof" for global warming-

Dr Biffra,

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

Dr Keiller has received no response.

The Biffra tree ring studies are vitally important to the conclusions reached by the U.N.'s IPCC report on global warming. . .

Death Bredon:

In the last ten years, the best temperature readings we have indicate nothing but a global cooling. I wonder many more consecutive years of cooling we need before the Global Warming Alarmists give up? My bet is that nothing short of a new ice age will persuade Al Gore and his lackeys.
