Government Climate Math : The Average Of Negative Numbers Is A Positive Number

It is actually 31 graphs representing all 1,600,692 July daily maximum temperature measurements in the NOAA US temperature record.

The average daily July temperature at all NOAA US HCN stations has dropped since 1895.

NOAA doesn’t adjust daily temperatures, but after they get done hacking the monthly temperatures, they turn a July cooling trend into a warming trend.

They accomplish this feat through an impressive hockey stick of data tampering, which cools the past about 1.5  degrees Fahrenheit and warms the present about 0.5 degrees Fahrenheit . Particularly striking is the spike in tampering after the 1998 El Nino.

Twenty eight out of thirty-one days in July have cooled since 1895, but through the magic of data tampering and junk science, NOAA turns this cooling trend into a warming trend.

The hottest day in US history was July 14, 1936 when afternoon temperatures averaged 96F, and there was a huge swath of 110+ degree weather across the US.
