Thirty-five years ago, NASA’s James Hansen predicted 4-6 degrees warming for the US from 1958 to 2020, and that the number of (typo in the article) 90 degree days at Omaha and Washington DC would more than double.
The actual average temperature increase in the US from 1958 to 2020 was less than one degree.
The closest currently operational USHCN station to Omaha is at Logan, Iowa. The number of 90 degree days there peaked in 1894 and 1936 (83) and have been declining sharply ever since.
The closest currently operational USHCN station in Virginia to Washington DC is at Purcellville. The number of 90 degree days there peaked in 1911 (96) and 1930 (89) and have been declining sharply ever since.
