I reported earlier on the Russian claims that the CRU had cherry picked the data from Russian weather stations. Deltoid points out that the analysis concerned actually confirms the recent warming from 1950 onwards:
The red and blue curves agree very well in the period after 1950, thus confirming the CRU temperatures. Well done, IEA!
The red and blue curves do diverge in the 19th century, but the one that provides more support for anthropogenic global warming is the blue hockey stick. The red curve shows warming in the 19th century before there were significant CO2 emissions, so it weakens the case that global warming is man-made. If CRU (not HAdley as claimed in the Russian news story) have “tampered” with the data, it would seem that they must have been trying to make a case against AGW.
The IEA analysis is, in any case, misguided. CRU has not released all the station data they use, so the red curve is not the CRU temperature trend for Russia at all. If you want that, all you have to do is download the gridded data and average all the grid cells in Russia. You have to wonder why the IEA did not do this.
