Like their fellow fraudsters and NOAA and NASA, CRU has made most of the 1940-1970 Northern Hemisphere decline in temperature disappear. Red is from the 1975 National Academy Of Sciences report.

Normalizing the data to 1970, there has been almost no increase in temperature since 1940. That is why they had to “remove the 1940’s blip.” Without this cheat, the global warming scam is dead.

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