I'm done, I don't like debating, I like conversating, which this is not.
well this is a debate forum
"I've just completed Mike's Nature trick of adding in the real temps to each series for the last 20 years (ie from 1981 onwards) and from 1961 for Keith's to hide the decline."
What do the suggestive "tricks" and "hiding the decline" mean? Is this evidence of a nefarious climate conspiracy? "Mike's Nature trick" refers to the paper Global-scale temperature patterns and climate forcing over the past six centuries (Mann 1998), published in Nature by lead author Michael Mann. The "trick" is the technique of plotting recent instrumental data along with the reconstructed data. This places recent global warming trends in the context of temperature changes over longer time scales.
Scientists at the University of East Anglia 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 revised figures were kept, but the originals — stored on paper and magnetic tape — were dumped to save space when the CRU moved to a new building.
The admission follows the leaking of a thousand private emails sent and received by Professor Phil Jones, the CRU’s director. In them he discusses thwarting climate sceptics seeking access to such data.
In a statement on its website, the CRU said: "We do not hold the original raw data but only the value-added (quality controlled and homogenized) data."
The CRU is the world’s leading center 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.
What a fun tactic this is. Instead of finding the scientific explanation needed to debunk the green house theory or debunk the data--skeptics are just going to start saying all AGW scientists are liers and all of the data supporting our claims are 'lies.'
At least I have a scientific explanation for debunking your so called data and charts, instead of just calling them lies. Real mature.
I'm not saying that all of our data is 100% true, but these few cases of 'hiding' or manipulating data, are few and far between; and there is still no explanation as to why the data is wrong. you can't just say something is wrong--it doesn't work.
Let me ask you, how many of the underlying papers have you read?
I've read more than a few going back more than a few years and while I don't have the statistical background to understand everything, but I do have some background in data reduction and analysis and I can understand the citation connections.
The whole reason this really is such a big deal is the amount of academic inbreeding that has gone on in climate science in the last 20 years. Mann cites Hansen who cites Jones who cites Briffa who cites Mann lather rinse repeat amongst about 25 guys. It means that anything that has been done wrong has propagated.
Keith Briffa had a tree ring reconstruction series called the polar urals about 10 years ago. Had data up through about 1990 or so. Showed the now ubiquitous hockey stick shape. Fast forward a few years and the data was updated to about 1999. A funny thing happened, with updated data, the hockey stick disappeared and Briffa stopped using the series in an updated paper.
Analysis based on the data quality criteria Briffa had outlined in both papers showed that the quality of the data had not changed with the update. The only thing that had changed was the result. That in and of itself is a problem because you don't just stop using good data that doesn't fit your hypothesis, its bad science.
What makes it worse is still to this day, nearly 6 years after the update, papers still cite the original Briffa paper with its original data, ignoring the updated data, and nearly every composite reconstruction in the last 10 years has used that Briffa reconstruction as a component. A series with updated data that does no reflect the outcome they're showing.
Thats a huge problem and its not an isolated one.
If we're going to completely rework the entire economy of the world, this is something we need to be damn sure of and make sure that everything is on the up and up...
