I'm no expert on tree rings- but, I'd be careful about the significance of the data. Many things effect tree ring size other than moisture- and this is an issue much more so here in the east than out west- including competition, diseases, age of the trees, etc. No doubt these factors are well understood by the experts- but I'd suggest that such a project should have to measure a great many trees to have confidence in the data. Maybe they did that, I didn't study that article.
