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.
In 1988, Hansen’s drought forecasts exactly inverted reality.
“Dr. James E. Hansen, director of the Goddard Institute for Space Studies, who presented recent data compiled from computer models, said that predicted regional effects of global warming show that the chances of summer drought in the low and middle latitudes would be 1 in 3 by the year 2030, as against 1 in 20 in the 1950’s.”
During the 1950’s the US was in drought most of the time, but droughts have been much less common over the past 60 years.
