James Hansen’s Blindness on Big Climatic Events
posted January 23, 2017 – Comments welcome
Massive Data Tampering Uncovered At NASA? The subject was recently discussed at NTZ (and illustrated with multiple graphs). With regard to two events they indicate simultaneously the same: A steep rise in temperature after World War One (WWI), and a large temperature drop when World War Two commenced in late 1939; as shown in the graphic from 1981.
In 1981, James Hansen was the Director of the NASA Goddard Institute for Space Studies. He was also the lead author of a seminal paper published in the prestigious journal Science entitled “Climate Impact of Increasing Atmospheric Carbon Dioxide“. In the paper, Hansen and his colleagues reported a rapid warming in the Northern Hemisphere of between +0.8 and +1.0°C between the 1880s and 1940, which then cooled by ~0.5°C between 1940 and 1970.
Already the length of the first Period 1880 to 1940 Hansen and colleagues interpreted wrong, which should have been divided in two parts:
Phase A) 1880 to WWI indicate a modest cooling by 0.1°C; and
Phase B) From the end of WWI to 1939 showing a steep temperature rise of about 0,9°C.
In addition they should have shown interest in the fact that the temperature turnaround commenced together with World War II around late 1939.
How could NASA scientists miss the clears signs of a strong correlation between the two World Wars and major climatic shifts during the first half of the 20th Century in 1981 (Further Reading ). How could they remain beaten with blindness until today?
