It would be good to remove at least part of the 1940s blip, but we are still left with “why the blip”.
So they did just that. They removed the 1940s blip, as well as all that unpleasant post-1940’s cooling. The animation below shows how the data has been changed since 1975.
At the time, there wasn’t any question about global cooling, so our friends at NASA and NCDC simply rewrote history.
