That wasn’t going to scare anyone about the mythical two degrees, so they changed the data to show 1.2C warming from 1880 to 2002
The next graph overlays the 2005 and 2015 versions, normalized to the 1880s. This view shows the massive alterations which NASA has made over the past ten years, which sit on top of all of their earlier massive data tampering.
Here is another view, which normalizes the data to the most recent common decade
Almost half of current global warming is due to the data tampering NASA and NOAA have done, just since 2005.
Gavin understands that he is working with a huge data set that is very difficult for most people to analyze, and that he can basically do whatever he wants to it and…
