In 1999, NASA’s James Hansen was troubled that his global warming theory was failing and the US was cooling.
Whither U.S. Climate?
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

In cooperation with NOAA, NASA simply cooled the past to make the post-1930 cooling go away.
NOAA knows perfectly well that the US is not warming.
