Or as an alternate title: “Why we find it difficult to trust certain climate scientists.”
This posting by Bishop Hill, telling the tale of the nefarious temperature reconstruction known as the Michael Mann hockey stick, from start to present, is an excellent summation for the layman reader struggling to understand the entire affair and why it is such an amazing pox on the conduct of science and practice of peer review. This sums it up quite well:
That the statistical foundations on which they had built this paleoclimate castle were a swamp of misrepresentation, deceit and malfeasance was, to Wahl and Amman, an irrelevance.
I highly recommend reading it, and Bishop Hill deserves thanks for condensing this affair into a readable story.
