GISS set a new record this month, reporting 0.639ºC above RSS – amplifying the Hansen lower troposphere cold spot (also known as a witches’ teat in November.)
GISS showed all of Russia 4-8C above the 1979-1998 baseline.
Now compare RSS at the same 1979-1998 baseline. Only a small portion of Russia is above 4ºC anomaly.
The next image shows in yellow exactly how much or Russia is above 4ºC anomaly. Maybe one fifth as much area as GISS shows.
When you are unconstrained by actual data, you can do anything you want. I’m guessing that someone decided they need to get above Scenario C. A year ago they did their big November cheat (shown below) and looks like they are back at it again.
