Hi Steve,
I am another lurker who visits daily but who is woefully befuddled by statistics and computer languages. I get the general idea of what you say and have certainly learned a lot about statistics just from reading your posts! You guys are the experts; nevertheless, I must say that I have always been a bit puzzled at the claims of accuracy in “reading” temperature to tenths of a degree from tree rings from 1000 years ago. It just seems like there is a lot of room for error and what I would call fuzziness in the numbers. It is not intuitively obvious that a tree ring or a bore hole can tell us what the temperature was 1000 years ago down to the tenth of a degree.

The “dozens of reconstructions” that agree are mostly by the same crew of scientists using overlapping data, and often with certain key ingredients like Yamal larch or bristlecone pine, and cherry picked data. Furthermore, in this ref:
Dergachev, V.A., Raspopov, O.M. 2010. Reconstruction of the Earth’s surface temperature based on data of deep boreholes, global warming in the last millenium, and long-term solar cyclicity. Part 1. Experimental data. Geomagnetism and Aeronomy 50:383-392.
they show that the various spagetti graph recons do NOT agree with one another at much of any time scale. It is only a see what you want to believe thing. If you include the chopped parts the lack of agreement is even worse.

I’ve had several conversations on this matter that all concluded in a very simple manor. I love this blog! I’ve seen different research that doesn’t seem to be manipulated like these figures. In fact I’ve seen a complete 1 degree C average annual change in amplitude of temperature. for the past few years. As far as 1998 is concerned, I was told that turbulence and large changes in temperature are typical and anything prior to the dates above are speculative. There is no telling the temperature in the beginning of the millennium because there was no impeccable way to tell. Therefore, the sample from which we have this data is not large enough to make a conclusion that accounts for large natural variance….Now that’s one argument..and its pretty solid, but remains ambiguous.

Many of us come here with much sketchier statistical credentials, but nevertheless can glean the essence of the disputed claims. We may well rely on other sources to fill in the knowledge gaps for us, or better explain the nuances of the finer points of respective arguments in layman’s terms. In my case my field is economics with a background in economic statistics, although for 26 years I’ve been in business and have met men who left school at 15 or 16 who have as good a grasp of economics that any Sandstone can elicit. Likewise there is no such animal as a climatologist, anymore than I and a bunch of clever mates, with the right connections, farnarckling ourselves into the corridors of power could claim to be the world’s leading experts in Humanology.

Yes I’ve formed a view about AGW from here and other sources as well as my own experience and no-one sums up my overall view better than a confessed warmist in Prof Richard Butler here-

A refreshing breath of fresh air, after a very tawdry episode for Western academe and the politicisation of science and the scientific method. For that breath of fresh air and no doubt more to come now that the way has been illuminated, I believe we owe a great debt to true men of science like Steve.
