Want to make it seem as if carbon-dioxide-aggravated warming is on the increase? Then massage the results by ignoring almost half of the available sample:
"They ignored data covering 40% of Russia and chose data that showed a warming trend over statistically preferable alternatives when available. They ignored completeness of data, preferred urban data, strongly preferred data from stations that relocated, ignored length of data set.
"On the final page, there is a chart that shows that CRU’s selective use of 25% of the data created 0.64C more warming than simply using all of the raw data would have done. The complete set of data show 1.4C rise since 1860, the CRU set shows 2.06C rise over the same period."
Good roundup of this latest drop-of-the-other-climate-shoe here, thanks to Russia’s Institute of Economic Analysis.
