According to the lads at CA, Hansen's methodology, when applied to the Russian weather stations, actually introduces an artificial cooling to records before 1987. Apparently, warming there is even worse than people thought!
Oh my! They'll be planting palm trees in Moscow. For Steve and co., this must feel like their paradigm is shifting without a clutch.
Just because S. Mosher and some of the climate accountancy boyz have tried to call me on this. The cool bias:
1) causes the warming trend during the first part of the century to be understated.
2) causes the cooling trend mid-century to be overstated.
3) causes the warming trend between 1975 and 1987 or so (when the bias comes to an end) to be understated.
It is only when you look from the beginning of the series to the warming from 1987 or so on that the bias seems to cause the warming to appear overstated.
So Nyah nyah freaking nyah.
