Al Gore the science guy

The crux of the argument is that the CRU cherry picked data following the same methods that have been done everywhere else. 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. [..] 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. More on this.
