Scientists have gone back and studied the “peer reviewed” climate change studies claiming the earth has warmed since the industrial age and found them to be based on fraud. Oops!
As Andrew Orlowski reports in The Register, the issue is the use of tree rings as a temperature proxy in order to ‘reconstruct’ past temperatures. The papers in question incorporated data from trees at the Yamal Peninsula in Siberia:
This dataset gained favour, curiously superseding a newer and larger data set from nearby. The older Yamal trees indicated pronounced and dramatic uptick in temperatures.
How could this be? Scientists have ensured much of the measurement data used in the reconstructions remains a secret — failing to fulfill procedures to archive the raw data. Without the raw data, other scientists could not reproduce the results. The most prestigious peer reviewed journals, including Nature and Science, were reluctant to demand the data from contributors. Until now, that is.
At the insistence of editors of the Royal Society’s Philosophical Transactions B the data has leaked into the open — and Yamal’s mystery is no more. From this we know that the Yamal data set uses just 12 trees from a larger set to produce its dramatic recent trend. Yet many more were cored, and a larger data set (of 34) from the vicinity shows no dramatic recent warming, and warmer temperatures in the middle ages.
In all there are 252 cores in the CRU Yamal data set, of which ten were alive 1990. All 12 cores selected show strong growth since the mid-19th century. The implication is clear: the dozen were cherry-picked.
Marry that with the fact that the records used to back up these AGW claims by other researchers have mysteriously disappeared and you have the scam of the century.
I’ve been saying since I’ve been blogging (March 2002) that AGW was a scam. A lot of people dissed me then, but it’s becoming clearer by the day that the skeptics (like myself) were right. The scam is falling apart.
And just in time, after Obamacare they want to ram through Cap and Trade. Not gonna happen.[ht: Amritas, Toren]
