I wish I could say the data below is a joke, but it isn’t.  USHCN temperature adjustments correlate almost perfectly with atmospheric CO2

US temperatures have not warmed over the past century (blue line below) – but NCDC alters the data to create the appearance of warming (red line below)

They accomplish this through a spectacular hockey stick of data tampering, which cools the past and warms the present.

Note the exponential growth of tampering, particularly over the past 15 years, which is very similar to the growth of CO2.

So I tried correlating the magnitude of the tampering with the amount of CO2 in the atmosphere, and found almost perfect correlation – shown below.

CO2 causes all kinds of great evil, but who would have guessed that it directly causes NCDC to release scientifically meaningless global warming propaganda?

Again, this sounds like a joke – but it isn’t. They…
