The graph above shows the full year to date adjustments to US temperature data being performed in the new USHCN v2.5 data set. The upwards adjustments for 2012 blow away the previous record. Note the sharp spike upwards since 2007. The total upwards adjustment relative to 1903 is more than two degrees!
NOAA has apparently been tasked with making 2012 the hottest year ever, regardless of the actual temperatures. Kudos to them for throwing out any need for integrity or honesty in reporting temperature data. The planet must be saved from global warming, even if it isn’t warming.
Their graph shows that there have only been three years when Americans knew how to read thermometers (2005-2007) and that since 2007 we have been getting exponentially more incompetent at recording temperatures.
There are no checks and balances in this system, and NOAA knows that they can get away with anything in the current political environment.
