Until a few years ago, nobody believed that the US had warmed since 1920.
In 1999 Hansen showed a strong cooling trend since 1930, and wrote the text below.
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
NASA GISS: Science Briefs: Whither U.S. Climate?
Phil Jones of CRU and NOAA said the same thing. No warming in the US.
February 04, 1989 Last week, scientists from the United States Commerce Department’s National Oceanic and Atmospheric Administration said that a study of temperature readings for the contiguous 48 states over the last century showed there had been no significant change in average temperature over that period. Dr. (Phil) Jones said in a telephone interview today that his own results for the 48 states agreed with those findings.

NOAA and NASA have since disappeared the 1930 to 1999 cooling trend, and turned it into a warming trend.
CONTIGUOUS UNITED STATES Climate Summary
NOAA and NASA have not only corrupted the temperature record, and they now describe every weather event as being extreme and unprecedented. Did Hansen lose his memory since 1999? He seems to have forgotten that the weather was just as bad or worse during the 1930s.
Hansen and NOAA have rewritten the past, in order to obtain money for the future.
