My previous animation of GISS US temperatures wasn’t quite right. What I had labeled as the 1999 version, was actually the 2000 version. The animation below shows the actual 1999 version.
As of 1999, 1998 was the fifth hottest year after 1934, 1921, 1931 and 1953. By 2000, it had been promoted to third hottest. B 2001, it had been promoted to the second hottest year, and by 2012 it was the hottest year.
An impressive demonstration of continuous and ongoing tampering – to create the impression of a non-existent warming trend.
Note the strong cooling trend which NASA showed in the 1999 version, and has since completely been erased.
