I feel your pain! If you follow this discourse as much as I do, you should have a very low regard for the likes of say, um ……Michael Mann and his apologists. He used (deliberately?) data in his 2008 paper from a Finnish scientist (Tiljander) that was upside down from what the data actually said. When this is pointed out to them, they categorically refuse to acknowledge the error, even going so far as to say the claim is bizarre! And we have a president that actually listens to him!!!
Interesting times.
