I fear the author is confused about the difference between accuracy and precision. Feel free to see my response to this post here:

Hey AJ – great post, as always when you discuss “Global Warming”. Just one little gripe: 4.2 cm = 42 mm, not the 420 mm you claimed.

This reminds me of the times you read a news story in the local paper where the style guide requires that all measurements also be given in metric units. So, we may have a story about some event that includes a quote from a witness: “… we were about a mile (1.60934 km) from where it crashed…”

Thus the trusty copy editor has taken a crude guesstimate of distance that may be +/- 25% and because of total ignorance has now given us a number that implies amazing accuracy.

Interesting theory. Great post. This talk about measurement significance and comparing past and present data reminds me of a story my partner on the survey crew told me about when he was a young apprentice chain-man years ago. They had chained themselves quite a long distance through the woods, up and down hills, but were only measuring to the nearest foot, not an attempt at any great accuracy. When they reached their end destination checking into a section corner or something, my partner was manning the head of the chain. He plumb-bobbed down to the corner, but couldn’t decide if it was like 15 hundredths of a foot, or 16 hundredths. He kept yelling out “15, no 16, no 15″. His party chief shot back amusedly — “well which is it, Ed, 15 or 16?? We don’t have all day!”
