There is an anti-science political agenda that is driving governments to fabricate excess global warming that really does not exist.
When one listens carefully, the political agenda becomes obvious. And government-funded scientists certainly listen very carefully to their paymasters.
As a result, faux-science is pervasive.
Case in point: NOAA's bureaucracy "scientists" are seemingly dedicated to squeezing manufacturing new global warming from any and all past empirical measurements, every single month - literally.
Their quasi-religious green jihad against the historical climate records has just been well dissected and documented by Walter Dnes. The adjacent chart is his analysis, with some additions by 'C3' (bold green, red and cyan lines, chart text and title added to his original).
===> The 'C3' horizontal dark green line is placed at zero degree change; vertical red dashed lines represent the beginning of periods with extreme high frequency of warming adjustments; and cyan vertical dashed lines periods represent the beginning of periods with extreme high frequency of cooling adjustments.
As the chart depicts, from the 1880s thru the mid-1920s, the monthly temperature adjustments applied by NOAA appear to be somewhat random in regards to cooling and warming changes.
From approximately 1926 on though, NOAA's warming and cooling adjustments give all appearances of not being the least bit random, but specifically designed to make historically documented warming periods cooler (such as the extreme warming of 1930s) and the more recent warming of the last two decades - made to appear even greater than reported during real-time.
The most recent decades of non-random adjustments are clearly an attempt by agenda scientists to rid the NOAA global dataset of the very inconvenient and embarrassing 21st century 'pause', also called the 'hiatus.'
What many don't realize (i.e., politicians, policymakers and the public alike) is that NOAA adjusts the monthly historical climate records every single month. And within the next few days, NOAA will release a new historical dataset ending at June 2015, which will likely include some 80% of the monthly records back to 1880 being "adjusted" once again. And they will do the same for the July 2015 historical dataset.
The constant manipulation and adjusting of empirical measurements simply never ends - it's ad infinitum, déjà vu.
The global warming political agenda demands a convincing story, and the falsification is necessitated when nature does not cooperate with the global warming narrative.
Walter's article goes into much greater detail with many more charts - a definite read by those interested in faux-science perpetrated by govt types. But he has only dissected NOAA's fabrication adjustments from late 2010 and forward to the present. In reality, the fabrication of all temperature records started much earlier though, which can be seen here, here, here, here and here.
For the record, it's definitely not only the U.S. climate agencies that are knee-deep in the 'sɔıǝuɔǝ' cesspool of data falsification.
Note: For those wondering how 'science' was transformed to 'sɔıǝuɔǝ', it was created here.
