USHCN advertises that they cheat by 0.6F, but it is much worse than it seems.
This is heinous enough, but I started thinking about it and realized that it doesn’t make any sense. We have seen hundreds of examples of them cooling the past, and their graph above doesn’t show that. So I calculated the actual adjustment by averaging all valid daily minimum and maximum temperatures at all USHCN stations (per year) and compared them to what they publish.
Their adjustment is much larger than what they admit, and it accounts for the entire claimed GISS US warming trend.
There has been no US warming. It was all manufactured by climate activists James Hansen and Tom Karl over the last decade.

Last week, scientists from the United States Commerce Department’s National Oceanic and Atmospheric Administration said that a study of temperature readings for the contiguous 48 states over the last century showed there had been no significant change in average temperature over that period. Dr. (Phil) Jones said in a telephone interview today that his own results for the 48 states agreed with those findings.

Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. The drought of 1999 covered a smaller area than the 1988 drought, when the Mississippi almost dried up. And 1988 was a temporary inconvenience as compared with repeated droughts during the 1930s “Dust Bowl” that caused an exodus from the prairies, as chronicled in Steinbeck’s Grapes of Wrath…..
in the U.S. there has been little temperature change in the past 50 years, the time of rapidly increasing greenhouse gases — in fact, there was a slight cooling throughout much of the country
