Notice these guys feel free to talk privately about points they ridicule publicly.
Another impression one gets from reading these papers is that these guys are really, really slow. I'm only a layman and I feel like I could run intellectual circles around these idiots. They are only beginning to dabble in the study of the medieval warming period, it appears from this letter. That's appalling incompetence on their part. They're way behind the power curve on subjects like these.
