“A recent study, Richey et al 2007, showed a warm MWP in the Pigmy Basin, Gulf of Mexico. Julie Richey made an effective presentation at the AGU Session showing an elevated MWP from her foram studies and, together with Alicia Newton who made a similar presentation. Richey said that they had faced unusual opposition from one reviewer who threw many roadblocks towards publishing their results – something that was unprecedented in their experience in presenting empirical results from a qualified laboratory.”

“But we know that Linah Ababneh updated the Sheep Mountain data in 2002. We also know that Linah Ababneh’s update, aside from finding a difference between strip bark and whole bark chronologies, did not replicate Graybill’s results and had no HS shape whatever. (Figures for Sheep Mountain for strip bark and whole bark from 1600 on are shown separately in the thesis.) So the Sheep Mountain chronology had been updated – why wouldn’t this update have been used, aside from it not having a HS shape?”
