In a few days, USHCN will release their temperature data for September.
It appears that NOAA made a decision in March, that 2012 was going to be hottest year ever in the US – regardless of the weather for the rest of the year. This decision has forced USHCN to upwards adjust YTD 2012 temperatures by more than three degrees relative to a century ago.
September was another cool month, and this will force USHCN to upwards adjust by even more. I am thinking that USHCN may ultimately have to upwards adjusted 2012 by as much as five degrees in order to achieve NOAA’s requirement of hottest year ever.
Khrushchev would be proud.
