In 1964, forty of the “world’s greatest authorities on climatology” met in Aspen and discussed “extraordinary climate variations in historic times”
They also discussed a reversal of warming after 1940.
There was unanimous agreement of experts in 1961 that the world was getting colder.
Michael Mann erased these extraordinary climate variations with his 100% fraudulent hockey stick, and then Gavin Schmidt erased the post 1940 cooling.
Make no mistake about it. The key players in this scam are committing fraud.
