To promote the global warming scare, Jane Lubchenco's NOAA continuously changes past temperature records to create fake warming - on a monthly basis
When one starts working with temperature data from various climate research agencies, one begins to notice rather bizarre style of science that would likely qualify as fraud in the mind of a normal person. In the case of NOAA / NCDC, this Obama "science" research group is demonstrably fabricating new "global warming" every single month. [Ed: Updates here and here]
Below is a simple example of the historical temperature record changes being done by Obama's NOAA on a monthly basis:
As can be seen, literally, Jane Lubchenco and her team are changing historical temperature records each and every month (note how they have "warmed" May 2008 since the NOAA report of December 2008) - even changing the historical record back to the very beginning, the January 1880 temperature record.
We asked a well known climate expert, Dr. Timothy Ball, if what Obama's NOAA / NCDC climate scientists are doing is common in the general science community: that is, is it common to constantly revise historical empirical evidence? Here is his response:
"Absolutely Not. There are adjustments to the raw data done by each nation when it collects the data. For me there are even questions about this, but it means that what goes to the World Meteorological Organization (WMO) and then to the Global Historical Climate Network (GHCN) and used as “raw data” is already adjusted. Post-collection adjustments are unnecessary and unacceptable."
With that said, it appears Lubchenco's NOAA is conducting a corrupt-like style of science that amounts to an Orwellian revision of history and empirical evidence. Not necessarily a surprise when a left / progressive 'Big Green' political hack is put in charge.
So what has been Jane's impact on temperature history with all these small revisions being done on a monthly basis? Well...one would expect that proponents of global warming alarmism would want to make modern temperatures warmer and earlier temperatures cooler.
Surprise! That exact politically-correct green agenda is robustly being carried out by NOAA's "scientists" as seen below.
The above record of temperature change over the four months since July 2011, by NOAA & NCDC personnel, is definitely not random. There is a significant man-made pattern to the cooling and warming changes.
Soooo...since Obama's "science" team has been in place, how much have they changed the historical temperature records?
Examining the historical record changes since 2008, the same pattern emerges with warming changes dominating after 1951 - "Unequivocal" global warming by humans indeed! Those cooling changes dominate the period prior to 1940. Lubchenco even provides "unequivocal" global cooling on demand - what an amazing goddess of left / liberal / progressive science!
Back to the facts. And when comparing the left axis of both charts, it becomes abundantly clear that all those small changes done on a monthly basis by NOAA starts accumulating to become ever larger changes over a few years. Obviously, Obama's team believes in man-made warming, especially when they can simply accomplish it on their PCs.
Most importantly for policymakers and the public, the above data falsification is good reason not to trust anything the green activist Jane Lubchenco says, nor any of her NOAA / NCDC minions carrying out her political agenda.
Special note: During the month of December 2011, NOAA / NCDC had at least 4 different 6 different versions of their global dataset available for download from its ftp site. Older versions are overwritten by the newer versions as they are uploaded by the agency (NCDC uses the same file name over and over apparently). NASA's GISS uploaded their first major revision of the year (December 2011) that affects all historical temperatures. The HadCRUT series has not had a major (entire historical dataset) revision this year from what we know.
