Corruption of climate science takes all sorts of forms - one is to fabricate global warming temperatures after the fact, using "correcting" algorithms that NASA / GISS favors, which it now appears to have been outsourced to a Google-funded effort - aka 'Google Warming'
Read here and here. The combined revelations of Climategate and Fakegate have well documented the culture of corruption and conspiracy that IPCC climate science has unleashed on the world over the past few decades. The revelations also unleashed the unbelievable condoning and cheerleading of actual scientific fraud, lies and fabrication by many in academia and journalism - is it any wonder the public's belief in climate science is plummeting.
One especially nefarious means of climate science corruption is to fabricate global warming temperatures from the original dataset of historical temperatures. Unfortunately for the public and policymakers, the fabricating of fake temperatures to boost the political agenda of global warming alarmists has been a preferred technique of major climate "research" agencies, even to the extreme of multiple fabrications within a month's time period.
For example, the adjacent chart reveals the recent 2011 fabrication of regional temperatures in Iceland that even the Icelandic Meteorological Office states is "grossly in error."
"...that GHCN have created a false warming trend in Iceland and Greenland , and GISS have amended every single temperature record on their database for Reykjavik going back to 1901...as the blue line shows, have magically made this warm period disappear, by reducing the real temperatures by up to nearly 2 degrees...Meanwhile the Iceland Met Office say that “The GHCN "corrections" are grossly in error in the case of Reykjavik”."
The adjustments done to historical temperatures during 2011 provides further evidence that climate data corruption is alive and well within the climate science community. But the big surprise is who actually performed the magical global warming of Arctic regions....
"To isolate these “abrupt shifts”, they use an algorithm. And it was changes to this algorithm in July 2011 by a Google Summer Student [add'l info here]...that suddenly produced this swathe of anomalous adjustments in Greenland, Iceland and Siberia. The Icelandic Met have confirmed that there have been no station moves or other non-climatic factors, which would have created the need for the adjustments in Iceland, and of course the algorithms in use previously in GHCN V2 and V3 did not spot anything unusual in the temperature data."
