I’ve written often how NASA and NOAA have corrupted the US temperature record to rid it of that inconvenient 1930s warmth, but their efforts to wipe out the warm past extend far beyond President Obama’s 57 US states.
They have done even more damage to the Northern Hemisphere temperature record since the 1975 National Academy of Sciences report. The animation below flashes between 1975 National Academy of Sciences temperatures and 2014 GISS temperatures.

It would be good to remove at least part of the 1940s blip, but we are still left with “why the blip”.
