Hansen has been deleting cooling trends all over the planet. The image above compares current GISS 1950-1998 trends, with those he published in 1999. He has erased historical cooling trends (blue) in North America, South America, Africa, the Arctic, Antarctica, and elsewhere.
He also has created data in the southern hemisphere which didn’t previously exist. Note how the area of grey has shrunk.
The color scales are shifted, but the legends are located below the maps – and you can see that the values have changed. The circle over Africa has changed from a -0.5C to -0.3C cooling trend, into a warming trend.HOW TO UNDO NASA TAMPERING
