1975
Having risen about 1.1 degrees C. between 1885 and 1940, according to one estimation, the temperature has already fallen back some 0.6 degrees, and shows no signs of reversal.
SCIENCE NEWS interviewed C. C. Wallen, chief of the Special Environmental Applications Division, World Meteorological Organization, at the wmo headquarters in Geneva. The cooling trend observed since 1940 is real enough, he says ……
the cooling since 1940 has been large enough and consistent enough that it will not soon be reversed, and we are unlikely to quickly regain the “very extraordinary period of warmth” that preceded it. Even this mild diagnosis can have “fantastic implications” for present-day humanity, Wallen says.
Hansen has been steadily cooling the 1930s since he got control of the temperature database, and now shows the 1930s as only slightly warmer than the very cold 1970s.
The graph below shows how Hansen corrupted the pre-1940 Northern Hemisphere temperature record – to eliminate data which contradicts his endless fear mongering.
Newspapers never forget what Hansen wants us to.

NCDC for the US shows no trend(0.02F) from 1918-1997 in annual temps. From 1895-1997 its 0.07 which really isn’t that significant. Add the remaining years you get 0.12F trend. Of course they have adjusted the hell out the dataset, but 80 yrs of no trend is significant.
