The five hottest July’s in the US were 1936, 1901, 1934, 1930 and 1931.
During July, 1936 – US afternoon temperatures averaged 33.6C (92F) compared to 30.1C (86F) so far in July, 2013.
The two coolest July’s occurred in 1992 (Pinatubo affected) and 2009.
USHCN hides this trend by cooling the past and warming the present. In order to get rid of that inconvenient hot July of 1901, they subtracted 2.5 degrees.
According to some honest people at NOAA, July, 1901 was the third worst heatwave in US history, with 9.500 casualties.
Had USHCN been able to adjust the temperatures at the time, most of those 9,500 dead people probably would have survived.
