I think there's a very strong possibility, DMcG, that Pete has never even heard of The Geological Society or the Royal Institution - let alone read any of their bulletins or journals. I think there's strong evidence, from his posts, that he gets all of his 'information' from 'creationist' sources.
When he makes statements like: "and much of the former evidence used to support the GTE, is now dropped or discredited ...", he means that he's read something to that effect in an article written by a, self-styled, 'creationist scientist' and posted on a creationist website.
