There is one grid box centered on 62.5 N-77.5 E, warming at 2 degrees  ( see Figure 2 on main page) and there are two stations with both Jones 1994,  GHCN  and GISS data.    Tarko Sale a rural site in the north and Aleksandrovsk, a small town on the river Ob in the south, . neither of which  has data before 1935.   Figure  4 shows the temperature data available and the folowing points are relevant.
 

• The Jones 1994 data for Tarko Sale extends only 28 years from  1967 to 1996 and  has 57% gaps.   It is not apparent why the thirty years of data prior to 1967 was not used but the data selected  inserts a warming trend over the last 28 years which would have been negated if the full length of Tarko Sale data were used.
• Tarko Sale  GHCN / GISS is  not homogenous with Aleksandrovsk prior to about 1960, so either Aleksandrovsk is too cool prior to 1960 or Tarko Sale is too warm.
• Data has not been found for Aleksandrovsk post 1989.
• It is a mystery how 2 degrees warming 1901-1996 can be computed for this grid box..
