There are 829 US HCN stations which have been continuously active since at least 1920. Fifty percent of their all time record maximums were set during the 1930s. Eighty percent of the records were set before 1960.
This agrees with the EPA graph below.
NOAA’s claims that the US is seeing unprecedented heat, are complete nonsense.
Steve, this needs to be updated by including data all the way to the end of 2012.
It includes all the hcn data up to yesterday. There were only two all time station records set in 2012.
@Steve: Speaking of much hotter, this is way off topic but I had to post it:
