It would be good to remove at least part of the 1940s blip, but we are still left with “why the blip”.
Some of the most prominent cooling was in Iceland, so Tom and Gavin simply made it disappear.
They were also quite successful at making the cooling in the US disappear.
The global warming scam is a complete fraud, which is why a personality like Barack Obama is so attracted to it.
