Maybe I'm misunderstanding your comment, but I think you should look back at some of Heller's videos. He shows both graphs back and forth of the two "temperature records" from NASA (might be NOAA, don't recall which). The graphs showed subtly different temperature records for key "inconvenient" years like 1930's: the significant difference between their "official" graphs being about ten years time elapsed and Climategate was perpetrated.

I was referring to the COP26 Summative Report, Deny, Deceive, Delay which is the subject of the video. I have looked a it, it isn't exactly an enthralling read, but all skeptic claims are dismissed as 'debunked', with no reference cited beyond the odd 'fact checker'. Their argument remains the 'consensus' claim and the appeal to authority, neither of which are valid scientific arguments.

100%. Which of these two types of people would be threatened by factual information: an honest scientist, or a liar?
