The graph below shows the numbers of USHCN stations which set or tied their all-time record for record heat, per year.
Note that NCDC’s fake record hot summer of 2012 didn’t even rank in the top 30. There is no time bias to this graph. If 2012 matched 1936, both years would be counted.
BTW – all-time record temperatures can not be explained away using TOBS – even by the worst climate crooks.
