Lying!-----NASA Caught Altering Temp Data To Support Warming Scam - Citizens' Task Force on Wind Power - Maine

We all know that some of our supposed trusted institutions like NASA have been captured and corrupted by the global warming cult. Here's a new study by a Danish scientist explaining the blatant manipulation of temperature data by NASA. - Richard McDonald/Saving Maine

• Danish professor emeritus at the University of Oslo, Ole Humlum, has exposed large ‘alterations’ made to the surface air temperatures by the GISS Surface Temperature Analysis — an estimate of global surface temperature change run by NASA.

GISS has altered its historical warming trend (between Jan 1915 to Jan 2000) from 0.45C to 0.67C, so reveals Humlum. This is a massive increase of 49%, and in turn means that almost half of the documented warming in that period—the majority of the 20th century—is due to administrative ‘adjustments’ made years after the original temperature measurements were logged.
Humlum provides the below graph.
What it shows is administrative alterations made to past temperatures since May 2008.
The blue lines show where historic measurements have been adjusted downwards, the red lines are where they have been adjusted upwards. 

In just the past 16 years, NASA has been altering historic inputs, cooling the past and warming the present.
