You can’t make this stuff up. Not only are they massively cheating, but they are lying about their cheating.

Attention Climate Conspiracists: NOAA Adjustments Show Summer 2012 3rd Hottest on Record
Attention climate conspiracists (lookin’ at you, Tom Nelson-bot): The NOAA/National Climatic Data Center (NCDC) analysis for August 2012 is in, and it shows that Summer 2012 was tied for the 3rd hottest on record in the contiguous 48 states of the U.S. That’s right, analysis of the raw National Weather Service (NWS) data and even the preliminary August adjustments from NCDC showed the summer would be at least tied with 2011 for second place, but the final analysis posted today lowered the August average by 0.1° to a tie with 2006 for 3rd place.

USHCN adjusted data shows 4th warmest, so they actually pushed it up one more notch rather than lowering it. The USHCN raw monthly data showed that the summer was 16th hottest on record.

Even after almost two degrees of upwards adjustments relative to 1901, USHCN was only able to cheat 2012 up to the #4 3 spot.
