In 2006, NASA knew that Antarctic temperatures had “decreased significantly” in recent decades.

While most of the Earth warmed rapidly during recent decades,surface temperatures decreased significantly over most of Antarctica.
This cooling trend was confirmed by a steady increase in sea ice surrounding the continent.
Satellites also show a cooling trend over the oceans surrounding Antarctica.
But this cooling didn’t suit the global warming agenda, so in 2007 NASA simply made the cooling disappear.
They used this completely implausible excuse for their data tampering
This image was first published on April 27, 2006, and it was based on data from 1981-2004. A more recent version was published on November 21, 2007. The new version extended the data range through 2007, and was based on a revised analysis that included better inter-calibration among all the satellite records that are part of the time series.
In other words, they are criminals committing fraud for political and funding purposes.
