Until about ten years ago, NASA showed the US on an 80 year long cooling trend, with the three hottest years being in the 1920s and 1930s. They have deleted the raw data from their website and blocked archiving, but John Daly captured it. It was originally located at this link :
and can now be seen here :
NASA has since rewritten US history and shows the same period warming – with 1998 as the hottest year.
James Hansen wrote this in 1999, before he decided to alter US history :
Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. The drought of 1999 covered a smaller area than the 1988 drought, when the Mississippi almost dried up. And 1988 was a temporary inconvenience as compared with repeated droughts during the 1930s “Dust Bowl” that caused an exodus from the prairies, as chronicled in Steinbeck’s Grapes of Wrath.
in the U.S. there has been little temperature change in the past 50 years, the time of rapidly increasing greenhouse gases — in fact, there was a slight cooling throughout much of the country
This sort of honest assessment was no use for obtaining funding or achieving radical left wing political goals, so Hansen created a hockey stick of adjustments to cool the past and warm the present.
The current version of the US temperature record from NOAA and NASA is a complete fraud, and fundamentally misrepresents changes to the US climate.
