I had the same thought - really cool that they calibrated it against modern measurements and were then able to find known historic anomalies in the data. On the other hand, it would be nice to get one or two stories where things are going better than expected, wouldn't it? Of course, then the deniers will just use them as evidence that everything is going to be OK, so we don't need to do anything.

Almost seems too-good-to-be-true right? Such a tight margin-of-error...
