Global warming science facts can be very disturbing at times - NOAA has been a leader in fabricating temperatures (faux warming), which many view as faux (fake) climate science

'C3' and others have often written about the fabrication of global warming by various climate agencies around the world. NOAA has been at the forefront of "adjusting" historical temperatures to fabricate increased warming for modern decades (1960's and more recent) and increased cooling for the earlier decades (pre-1960's).
The adjacent chart visually depicts the changes to monthly global temperatures that NOAA has made since 2008 (updated through May 2012). Since 2008 they have "adjusted" every single month back to January 1880 (that's 1,548 months of "adjusted" empirical evidence through 2008) except for one solitary month (December 2006).
The chart is a plot of coolest temperature adjustment to the warmest temperature adjustment - from left to right. Summary factoids below:
1. Out of 1,548 monthly temperature records, NOAA "cooled" 754 months
a. 49% of all months had their historical temperatures lowered
b. Total "cooling" applied was -29C degrees
2. Out of 754 "cooled" months, only 17 of those had dates post-1959.
a. That's only 2% - one would naturally expect close to 50% of all cooled months to be post-1959 if adjustments were applied with robust scientific rationale
3. Out of 1,548 monthly temperature records, NOAA "warmed" 793 months
a. 51% of all months had their historical temperatures raised
b. Total "warming" applied was +23C degrees
4. Out of 793 "warmed" months, 570 had dates post-1959
a. That's 72% - not exactly random; more like adjustments due to a non-scientific rationale
5. Extreme "cooling" adjustments - 223 months exceeded -0.5C deg
a. 30% had extreme cooling applied
6. Extreme "warming" adjustments - 70 months exceeded +0.5C deg
a. Only 9% had extreme warming applied
7. One example of wacky (nonsensical) adjacent temperature adjustments
a. December 1881 = +0.10C deg (adjusted up since 2008)
b. January 1882 = -0.02C deg (adjusted down since 2008)
Keep in mind, when reviewing the above factoids and chart that these are NOAA adjustments made to historical temperatures (January 1, 1880 thru December 31, 2008) since 2008. The NOAA adjustments to the historical temperature dataset made prior to 2008 have also been massive, as indicated here by an Oak Ridge National Laboratory analysis.
Clearly, since the Obama election of 2008, NOAA has pursued a frequent policy of temperature adjustments (literally monthly) to meet some non-scientific objective. Their methodology has primarily consisted of lowering the majority of temperature records prior to 1960 and raising those post-1959. The cumulative effect of all these adjustments is to build a better case that modern warming is a result of human CO2 emissions.
No other major climate science agency has pursued such an aggressive (ie, frequent) process of fabricating temperatures.
Finally, some proponents of the NOAA methodology attempt to rationalize all these adjustments as "quality control/management" which is patently absurd. During 2012 alone, NOAA has "quality control" adjusted the entire historical temperature record at least 18 times - for example, they have reported at least 18 different temperatures for January 1880 over the past 5 months. This is not "quality control" in any sense that experts of quality control would understand. Instead, it's ludicrous faux-science for non-scientific reasons, month after month, plain and simple.
