Hansen wrote this in 1981
A remarkable conclusion from Fig. 3 is that the global temperature is almost as high today as it was in 1940.
At the time, he showed 1980 temperatures about 0.15C cooler than 1940.
Now, NASA shows 1980 temperatures about 0.2C warmer than 1940. They made a relative shift of 0.35C, far exceeding Wigley’s hoped for 0.15C
