NASA has completely erased the post-1940 cooling. They turned Tom Karl’s 1921-1979 cooling into 0.5C warming, and have more than doubled 1880 to 1999 warming since their own 2001 temperature graph. Malfeasance like this in most professions would have serious consequences for the perpetrators.
The NASA temperature record is wildly unsupportable garbage. Unfortunate that clueless people like Steven Mosher and Brian Cox believe it is gospel truth.
