(CNN) — The mainland United States, which was largely recovering Monday from a near-nationwide heat wave, has experienced the warmest 12 months since record-keeping began in 1895, a top government science and weather agency announced Monday.
The report from the National Climatic Data Center, which is part of the National Oceanic and Atmospheric Administration, does not take into account blistering heat from this month, with 2,116 high temperature marks either broken or tied between July 2 and July 8 in communities nationwide.
We have been hearing that the last 12 months is the warmest in US history. It is not surprising, because USHCN is massively cheating – by adding 2.5 degrees on to 2012 temperatures relative to 100 years ago.

Data is taken from these three files.
Note that it is not TOBS which is the big offender. They have some massive data tampering going on after the year 2000. The US temperature record is corrupted beyond comprehension.
