Below is an important presentation by Steve McIntyre to the Heartland Conference on the history of the tree ring shenanigans of Jones, Briffa and Mann, as well as the phony efforts to investigate the dispute.

McIntyre does not address the issue of how or whether this behaviour is shaped by the need to acquire grant money. Chuck
