Like everyone else who participated in this review, I agreed not to cite, quote or distribute the draft. The IPCC also made a further request, which reviewers were not required to agree to, that we “not discuss the contents of the FOD in public fora such as blogs.”
Given what I found—systematic fraud—it would not be moral to honor this un-agreed to request....
