Why don't they do their own [temperature] reconstructions? If they want to criticise, they should write their own papers Didn't Jon Graham-Cummings just publish an article about having done just this, and finding an error in the data? Of course, people like JGC couldn't do so before, because Jones and his colleagues kept the raw data secret. Edit: here's JGC's posting about his article: http://news.ycombinator.com/item?id=1128782 http://news.ycombinator.com/item?id=1128782
